Drive the outfit love a car that gens can be him normally sticks sun film. However present car sticks velar breed various, the good and bad are intermingled, as a result of average car advocate insufficient to intellectual understanding of film, the blind place before sticking film brings about an interest to be damaged to also happen constantly. To this, the concerned expert of film of dragon of member of association of international window film, to how choosing correct car film made following introductions:
When people is choosing sun film, better to obtain adiabatic effect and good illicit close sex, often can choose brunet sun film. Little imagine, general black paper " film " , tea paper is essential not adiabatic. Velar heat insolation was mixed whether is thermal insulation contained to concern in film. Although professional velar color is very shallow, can issue burning sun however the sun radiate quantity of heat of 900 tile holds back every square metre 700 tile, the cheap brunet film that does not have professional block secondary floor can cut off only at most the quantity of heat of 300 tile. So car film heat insolation reached the size of adiabatic ability, whether should have advanced thermal insulation to make a technology with the manufacturer closely related.
At present car film distributes film of the coloring that it is glue and metallization film basically, both as colour television machine of PK of monochrome television machine, difference of heat proof quality is very big. Still the businessman alleges his film can cut off the infrared ray of 90% , what the infrared ray in radiate of little imagine sun carries quantity of heat is left and right sides of half of sun total caloric only, this kind of view is the method of heat insolation of a kind of arrogation only. Professional adiabatic index should be total solar energy cut off rate. Prevent ultraviolet ray same also, professional film is in velar layer mix into entered UV absorbefacient, can cut off the ultraviolet ray of 99% , common car film does not have this function.
Car advocate to ultraviolet illuminate defend cannot ignore absolutely. Drive below burning sun, the skin suffers ultraviolet enroach on for a long time, can quicken skin ageing, serious can cause skin cancer and eye ministry disease. In the meantime, dragon film expert reminds broad car even advocate, film is blocked to want special discretion before the choice. Because, it is the biggest that the windshield before passing enters the sun radiate quantity of heat inside the car, if can choose high grade sun film, can cut off the quantity of heat of 50% enters a car inside, but before the requirement that blocks film is more slashing, technical content is higher also, what stick film to answer with clarity of line of sight, glass blocks before increasing glance and do not affect drive safety is principal premise. The beard after glass is being blocked to stick film before national the Ministry of Public Security sets achieves the light transmittance of 70% , at present on the market before block film mostly VLT light transmittance is 60% , cut off to what sun radiate heats up only 30% the left and right sides, glance be as high as 20% .
