1. In terms of heat insulation performance, metal films significantly outperform ceramic films. Metal films are made from various precious metals using advanced processes like magnetron sputtering, allowing for selective passage of light. Conversely, ceramic films, composed of ceramic materials, may produce secondary heat radiation when the ceramic layer reaches thermal saturation. Consequently, metal films provide superior heat insulation compared to ceramic films.

2. From the perspective of light transmission, metal films tend to have darker colors, resulting in reduced transparency but offering better privacy. Ceramic films, on the other hand, feature lighter colors, allowing for more light transmission but providing somewhat weaker privacy. For car owners who frequently drive at night, opting for ceramic films can be a practical choice, as it aids in better visibility during nighttime road conditions.

VLT=light transmittance, UVR=ultraviolet rejection rate, IRR=infrared rejection rate. To put it simply, the primary focus should be on maximizing the values of the two dash lines, which are UVR and IRR, while Visible Light Transmittance can be adjusted according to individual preferences.

When selecting a front windshield film for your car, it's important to consider the following factors:

A. Avoid Excessive Heat-Reflective Films:

Highly heat-reflective front windshield films are typically made from multiple layers of metallic materials that use metal components to reflect solar heat. The higher the heat-reflectivity, the more metal content is usually present. While this enhances heat insulation, it often comes with various negative issues. For instance, it can interfere with mobile phone signals or disrupt the normal use of GPS systems. Additionally, films with high metal content tend to be thicker, making installation more challenging.

B. Darker Tint Doesn't Mean Better Heat Insulation:

Front windshield films must allow over 70% light transmission to ensure safe driving. If the film tint is too dark or too deep, it can lead to prolonged visual fatigue for the driver and increase the risk of traffic accidents, especially during nighttime driving.

C. Avoid Excessive Reflectivity:

If the front windshield film has high reflectivity, it can cause mirror-like reflections on the windshield when there is light inside the vehicle (such as reading lights or dashboard illumination) during nighttime driving. This directly affects the driver's ability to see the road and can lead to traffic accidents.

D. Ensure High Clarity:

Front windshield films vary in material quality, and lower-quality materials may exhibit varying degrees of wave-like patterns or an orange peel texture. This can create a sensation of waviness in the scenery while driving. Prolonged exposure to such conditions can lead to visual blurring, dizziness, reduced vision, nausea, and discomfort. Therefore, high clarity is a primary criterion when selecting a front windshield film.

1. In order to ensure that the car film and the glass are completely adhered after the film is applied, the car film cannot be cleaned and the defogging line switch cannot be turned on within a week. Try not to let the sun directly expose the glass, which will cause blistering. You should turn on the air conditioner in the car to allow air to circulate inside and outside. The breathability of the car film itself will form a natural solidification to ensure that the glue and the glass are completely combined after the car film is installed. , in order to form a safe and explosion-proof effect.
2. After applying the film, a little moisture will inevitably remain between the car film and the glass, which may cause small bubbles or slight ripples, resulting in blurred vision. This is normal. After being exposed to the sun, it will disappear naturally after 4 to 10 weeks. If the obvious phenomenon still exists after a period of time, be careful not to handle it without authorization. You should find a professional technician to handle it.
3. When cleaning the glass, it is forbidden to use solvents with high acidity and alkalinity for cleaning, and try not to let oily liquids such as leather oil get on the car film. You can use clean water or non-acidity and alkalinity cleaning fluids on the market. Most glass cleaners work well for cleaning car film. A more suitable cleaning solution for car films is a 10:1 dilution of water and household detergent.
4. The surface hardening of the car film is limited. To avoid scratching the car film, do not use any cleaning supplies with hard particles such as brushes and sandpaper. It is correct to use a soft cloth or sponge to clean the surface of the car film. Clean the cloth outside the car body, and do not use it to wipe the car film, because the cloth used outside the car body is easy to contain fine sand, which is also one of the factors that cause scratches on the car film.

Is féidir le wrinkles ar dhromchla an scannáin a bheith ann le linn an scannáin a thriomú agus a leigheas. Tá trí chineál wrinkles ann go ginearálta: wrinkles a tharlaíonn le linn an iarratais tosaigh ar an scannán, wrinkles coirníní a tharlaíonn le linn iarratais arís agus arís eile scannáin, agus wrinkles de bharr gníomh na ngás aigéadach taobh istigh den oigheann.

After a film is applied to flat glass, the overall light transmittance of the film plus glass will be lower than that of the original pure glass. All quality inspection standards should be based on the absence of defects in the glass itself.
Since solvents are used during installation, it will take a certain amount of time for the film to be fully attached after it is applied. Although some water cannot be seen, it still remains between the film and the glass. The complete adhesion of the film is also commonly referred to as the "film drying time". As the film dries, the viscosity of the glue will gradually increase. The speed of the film drying has a certain relationship with the thickness of the film and the metal content. Weather factors also have an impact on how quickly the film dries.
Before the film is completely dry, inspection of optical quality can be performed. It should be noted that some phenomena before the film is completely dry, such as blisters, image deformation of objects due to water, and water mist, are all normal phenomena.
The naked eye inspection of filmed glass should be from indoors to outdoors and from the correct angle, and the distance should be within 2 meters. The inspection should be conducted under normal natural light during the day and should not be directly exposed to the sun. The inspection area should be within 5 cm from the glass frame.
The installation will be considered qualified if there are no following conditions (except for normal phenomena that occur during the film drying process): debris, hair and fibers, glue agglomeration, fingerprints, bubbles, scratches and cracks in the film, and film body deformation , oil stains in the film, warped edges of the film, and knife marks. The above detection should be done within 24 hours after installation.

Is gá roinnt bearta cosanta a ghlacadh le linn scannán fuinneoige gluaisteán a thógáil chun sábháilteacht an phróisis tógála a chinntiú agus cuma agus trealamh inmheánach an ghluaisteáin a chosaint. Seo roinnt príomhbhearta cosanta:

1. Suiteáil pillíní cosanta ar na cochaill tosaigh agus ar chúl agus ar dhromchlaí eile chun dromchla péint an ghluaisteáin a chosc ó bheith scríobtha le linn an phróisis tógála.

2. Bain úsáid as clúdach cosanta plaisteach indiúscartha ar an taobh istigh den doras chun an sreabhach suiteála a spraeáil a chosc nuair a bhíonn an scannán fuinneoige á chur i bhfeidhm as an doras, an t-urlár agus na suíocháin a stainniú.

3. Cosain asraon aer an oiriúntóra aer le linn na tógála chun sreabhach suiteála a chosc ó sileadh isteach sa asraon, rud a sheachaint teip ciorcad gearr ar fhearais leictreacha agus cainteoirí sa charr mar gheall ar thaise.


Ina theannta sin, tá roinnt ceanglais ann a bhaineann leis an scannán fuinneoige féin:

1. Níor cheart go mbeadh an iomarca lochtanna sa scannán fuinneoige, agus níor cheart go mbeadh aon creases, boilgeoga nó scratches ar dhromchla an scannáin.

2. Le haghaidh barr na fuinneoige rollta síos, ba cheart bearna beag 1-2mm a chur in áirithe chun breathnóireacht garbh a éascú agus gan a bheith faoi deara go héasca.

3. Ba chóir go gclúdódh an scannán fuinneoige an limistéar glaze dubh den fhráma gloine chun a chinntiú nach sceitheadh ​​​​aon solas amach. Ag an am céanna, níor cheart go mbeadh aon chumhdach imeall ann chun cuma álainn agus comhordaithe a choinneáil.

De réir modh aicmithe scannáin ghloine ag an gCumann Idirnáisiúnta Scannán Gloine (IWFA), is féidir scannáin ghloine gluaisteán a roinnt ina thrí chineál bunúsacha:

​

1. Tagraíonn scannán dathaithe (neamh-fhrithchaiteach, le frithchaitheamh ghathanna infridhearg). Níl ciseal miotail ag an gcineál seo scannán agus níl aon fheidhm aige ghathanna infridhearg a léiriú. Tá rialú glare agus feidhmeanna inslithe teasa áirithe aige. Imríonn sé ról inslithe teasa go príomha trí fhuinneamh na gréine a ionsú agus ansin é a scaoileadh amach. Tá an éifeachtúlacht inslithe theirmigh i bhfad níos ísle ná an scannán machnamhach.

​

2. Tugtar scannán ardfheidhmíochta ar an scannán ilchodach de scannán ruaimniú agus scannán miotalaithe bhfolús (machnamh) sa tionscal. Is gnách go bhfuil an scannán ardfheidhmíochta seo comhdhéanta de shraith de scannán ruaimniú mórchóir agus sraith de scannán alúmanaithe i bhfolús. I gcomparáid le scannáin daite neamh-fhrithchaiteacha, tá tarchur solais infheicthe níos airde aige agus ráta inslithe teasa níos airde. Mar sin féin, scaipfidh an ciseal daite solas, rud a fhágann saobhadh amhairc, agus mar sin tá an soiléireacht níos ísle. Difríocht.

​

3. Scannán miotail sputtering Magnetron (machnamh), ar a dtugtar scannán miotail íon freisin. Is scannán é seo leis an leibhéal is airde de theicneolaíocht déantúsaíochta scannán gloine. Úsáideann an scannán seo próiseas sputtering magnetron chun an tsubstráit scannáin a chóta le sraith de chótaí ian miotail éagsúla a bhfuil frithchaiteacht infridhearg an-ard acu. Is iad na miotail a úsáidtear de ghnáth copar, cruach dhosmálta, cóimhiotal nicil-cróimiam, etc. Déantar dath an scannáin a chinneadh go hiomlán ag an miotail plátáilte.

Thug athfhorbairt feidhmeanna scannán fuinneoige gluaisteán an chéad ghlúin de theicneolaíocht sciath agus ilchodach sna 1960í, ar a dtugtar scannán páipéir tae go coitianta. Is é príomhfheidhm scannán den chineál seo ná solas a bhlocáil agus go bunúsach níl sé inslithe. Díreach cosúil le sunglasses, ní féidir leis ach dearcadh an tsolais amhairc a athrú. Thairis sin, tá soiléireacht an scannáin páipéir tae an-íseal, agus tá an boladh formaildéad an-tromchúiseach. Níl sé oiriúnach ach do ghluaisteáin phaisinéirí, tochailteoirí, etc., a úsáidtear chun earraí a shuiteáil.



Is é an dara glúin scannán daite ag baint úsáide as próiseas ruaimniú. Táirgeadh an cineál seo membrane sna 1970í. Is próisis ruaimnithe domhain iad an chuid is mó de na seicní atá ar an margadh faoi láthair. Úsáidtear an modh ruaimniú domhain chun ionsúirí teasa a chur leis chun na gathanna infridhearg a ionsú sa ghrian chun éifeacht inslithe teasa a bhaint amach. Toisc go n-ionsúnn sé solas infheicthe freisin, ní leor an tarchur solais infheicthe. In éineacht le teorainneacha an phróisis ruaimnithe féin, tá an soiléireacht sách bocht. Míbhuntáiste mór eile a bhaineann le scannán daite ná go laghdaítear a fheidhm inslithe theirmigh go tapa, agus go bhfuil sé éasca le céimnithe. Ní hamháin go mbeidh go leor scannán daite céimnithe tar éis bliain go leith, ach ní bheidh siad inslithe a thuilleadh agus féadfaidh siad blister fiú, rud a chuireann isteach go mór ar an gcuma amhairc. Tá an cineál scannáin seo oiriúnach go háirithe le haghaidh tástálacha inslithe teasa an toirt. Is minic a úsáideann siopaí 4S tréith scannáin daite chun teas a ionsú meandarach do chustaiméirí, mar sin ní gá scannáin ruaimnithe níos lú a sheolann siopaí 4S a thabhairt.

Tá roinnt príomhghnéithe teicniúla agus eolas a bhaineann le scannán gloine sábháilteachta agus scannán cruthúnas pléascadh:



1. Cóireáil Friotaíocht Aimsire: Is féidir le scannáin PET-bhunaithe a mhaolú agus a dhífhoirmiú ag teochtaí arda (thart ar +50°C) agus féadfaidh sé reoite agus crack ag teocht íseal (thart ar -10°C). Mar sin féin, le cóireáil friotaíochta aimsire chun cinn, is féidir le scannáin PET-bhunaithe a n-airíonna fisiceacha agus ceimiceacha a choinneáil i raon teochta leathan, ó -70°C go +150°C. Déanann sé seo oiriúnach iad le húsáid i gcoinníollacha comhshaoil ​​éagsúla.



2. Teicneolaíocht Scannán Comhlacht Dath Bunaidh: Úsáideann na scannáin seo foshraitheanna PET déanta as roisín comhlacht dath bunaidh, ag cinntiú nach bhfuil siad céimnithe le himeacht ama. Cuireann dáileadh cothrom na móilíní roisín seo le hinfheictheacht den scoth tríd an scannán.



3. Teicneolaíocht Brataithe Miotail Magnetron Sputtering: Is próiseas é sputtering Magnetron a tharlaíonn i seomra mór bhfolús le brú íseal agus gás támh. Is éard atá i gceist leis ná spriocanna éagsúla miotail nó cóimhiotail a thuar le hiain luchtaithe, rud a fhágann go gcruinníonn adaimh miotail ar dhromchla substráit PET. Cruthaíonn an próiseas seo scannáin le dathanna uathúla agus cobhsaí, ardleibhéil roghnaíochta tarchurtha solais, agus airíonna rialaithe solas na gréine den scoth.



4. Teicneolaíocht Chiseal Cóireála Leictreamaighnéadacha Ghreamaitheacha Bhrú-íogair: Déantar cóireáil leictreamaighnéadach ar an gciseal greamaitheach brú-íogair. Freagraíonn an ciseal seo brú fiú sula gcuirtear i bhfeidhm ar an ghloine é, rud a ligeann do na móilíní greamaitheacha a atheagrú agus ciseal cosanta a fhoirmiú. Nuair a chuirtear brú i bhfeidhm, déanann an greamachán athbhrú, ag méadú go suntasach ar neart na gloine. Soláthraíonn an ghné seo friotaíocht tionchair agus cuidíonn sé le cosc ​​a chur ar ghloine ó bhriseadh ar thionchar.

There are four main types of window films:

Dyed Films: These films originated in the 1930s and were primarily designed to block intense sunlight. Dyed films do not provide significant heat reduction and are mainly used for glare reduction.

Dyed Hybrid Films: Introduced in the 1960s, these films use deep-dyeing techniques and incorporate heat-absorbing agents to reduce heat. While they do provide some heat rejection, they also absorb visible light, leading to lower visible light transmission and reduced clarity. These films can deteriorate over time and tend to fade, but they are relatively affordable.

Vacuum Coated Films: Emerging in the early 1990s, vacuum-coated films use advanced technology to evaporate layers of metals onto a substrate to achieve heat rejection. While these films offer better and longer-lasting heat reduction compared to dyed films, they may compromise clarity and can have higher reflectivity, which can affect visibility.

Sputtered or Metalized Films: The most advanced type of window film, sputtered or metalized films, emerged in the late 1990s and have seen continuous technological improvements. These films utilize a process called sputtering, which evenly deposits metal particles like nickel, silver, titanium, or gold onto a high-tension PET substrate using a sophisticated multi-chamber, high-speed rotating system. Sputtered films provide excellent heat rejection, low reflectivity, and long-lasting color stability. They also maintain high clarity, making them the top choice for high-quality window films.

Misunderstanding 1: Choose dark film
When people choose solar film, in order to obtain better thermal insulation effect and good privacy, they often choose dark-colored solar film. In fact, ordinary "black paper membrane" and "tea paper" are not insulated at all. The thermal insulation effect of the membrane is determined by whether the membrane contains an insulation layer. Although the professional film is light in color, it can block 700 watts of heat under the scorching sun (solar radiation is 900 watts/square meter), while the low-end dark film can only block 300 watts of heat. At present, the films produced in Southeast Asia are basically glue-dyed films. Compared with the metallized films produced in the United States, just like black and white TVs compared to color TVs, the thermal insulation performance is very different.


Misunderstanding 2: Apply two layers of film
Applying two layers of film usually causes the following two problems. First of all, the adhesive design of the film is for sticking on glass, which cannot guarantee the perfect bond between the two layers of film. Secondly, the second film may immediately stick to the first film, leaving no time to squeeze out the moisture. Usually, applying two layers of film is easy to produce bubbles and water pockets, and these will become larger and more numerous over time. In fact, if you need to apply film to make your home darker, you can choose a film with low light transmittance instead of applying two layers.


Misunderstanding 3: Look for the infrared blocking rate
95% infrared blocking rate means 95% heat insulation? This is a wrong concept. Only 53% of the sun's radiant heat comes from infrared rays, another 3% comes from ultraviolet rays, and 44% comes from visible light. So even if a film can block 100% of infrared radiant heat, there is still 47% of solar radiant heat to deal with.
