glass explosion-proof film has become a more and more popular one,today and we talk about the construction glass explosion-proof film of those things.Among them,quality is the top priority.Accordi -ng to the investigation,there are several reasons affecting the quality of building glass.
Explosion proof film:
1.Transmittance and clarity:
This is an important performance of the building glass explosion-proof film.The color of the film
can be light or dark,and the light transmittance can be high or low.If you choose a variety with high li -ght transmittance(close to the color of the glass),it will not affect the light at all.High quality film will -not cause object deformation,affect the line of sight.
2.Insulationg performance:
Thermal insulation performance is not only an important standard to evaluate the quality of a ther -mal insulation film,but also a key to determine the price.Want to understand the adiabatic effect that sticks film,can judge with intuitionistic method,blocked the sun with the glass that stuck film namely or illuminate below lamp of iodine tungsten,go feeling its adiabatic effect with the face or hand.Note that currently there are some testing heat insulation data machine on the market,because almost all of them are infrared fixed band testing,the data is not accurate,some data is very high,but there is no heat insulation effect,consumers till believe their skin feeling.
3. Explosion-prrof performance:
This is another important performance that involves security.The material of general or inferior stic -k film and good differ,its film piece is very thin,feel soft,lack enough tenacity,not be able to bear or e -dure ultraviolet ray irradiation,easy ageing hair is brittle,when encounter accident bump or outside c -ontent to hit,film piece breaks very easily cannot stick glass together.Good building glass explosion- proof film is made of special polyester film as the substrate,thermal insulation and explosion-prrof fil m itself has a strong toughness,enhance the glass instant resistance to hit the strength,and with spec -ial pressure-sensitive adhesive,when the glass encounter accidental collision,the glass is broken by
film bonding will not splash hurt people.
4.Uv barrier performance:
Stick film ultraviolet ray cut off rate to have 95% above commonly,the ultraviolet ray cut off rate
Of high grade film amounts to 99% above.Ultraviolet ray cut off can prevent indoor article
Effectively fade,ageing,prevent indoor,personnel skin to be burned,suntan ,bask in ageing.
5.Feel and wear resistance:
Good stick film feels thick and smooth,the surface has anti-scratch layer,not easy to scratch the
Surface.The low-grade membrane feels thin and brittle,which is easy to be scratched,and the
Membrane surface is not clear.
6.Color:
Construction glass explosion-proof film usually adopts the method of body infiltration dyeing and
Sputtering metal to make the film colorful is called natural color film,and the method of sputtering metal to make the film metallic color to heat insulation,heat insulation effect is poor,not fast light is very easy to fade,fade without heat insulation effect.
