 Sand problem 
 Layman see the technical staff posted insulation film, all thought is very simple, as long as ripped from the film, spray some water, Nianshang Qu cut several times to scrape the water to come out and completed, in fact, film technology, esoteric is rarely The people would go to the detailed study. 
 Sand sources:

 Second, dust 
 Many film places no closed room, some people at the roadside or arcade sticker size car zips stirred up a lot of dust, and sometimes when the wind speed the larger the dust, so if there is no film of the closed room must be closed all doors to posted. 
 Third, work clothes 
 When you open the transparent part of the insulation film to produce a large number of static electricity, if the film when you empty the clothes is wool, or stick to cotton dust, wear clothes not suitable for film, because, of cotton or wool clothes impurities electrostatic adsorption to the membrane above.

 Five, coverings or object 
 The same electrostatic reasons, some coverings with rabbit fur, fox fur or cotton as raw materials, film dashboard and seat application cortical or non-woven towel cover, open the paper not too close to objects, so as to avoid objects dust are absorbed by static electricity. 
 Six, open the paper door switch 
 Glass after washing or open the paper not to allow the vehicle to the door switch, sometimes slamming the door will cause the air quickly flows into a lot of dust or sand. 
 7, air-conditioning wind speed over 
 Summer posted insulation film season, and very high temperatures inside the car in the sun, the film is inevitable in the car air conditioners, air-conditioned wind speed should open the paper to the minimum until the Chai Wan paper, paste glass open wind speed, to avoid the car dust flying everywhere. 
 Eight, not clean the bottom of the sprinkler 
 The construction of most of the sprinkler on the floor mat or chair cover, the bottom is often not clean, when you open the paper sprinkler shaking on the paper side, the bottom of the sand, or other impurities will fall paper, so when we use the sprinkler should be scrubbed at the bottom of. 
 Nine, hand-pinched part 
 Must be after the open transparent paper with two fingers to pinch the insulation film, pinching part will fingerprint and sand, the key is pinching the part should be minimal, some. 
 Ten, the wiper is incorrect

Used cars or triangular windows should be noted that the flushing, but can not flush at the top, so as to avoid the debris with the water fell. 
 XII pay attention to the items inside the car 
 Chai Wan paper, spray water who are heading to the sticker on the glass, and sometimes the film touches the dashboard, steering wheel, mirrors, seat cover, bezel or top seam, audio, etc., will be stained with debris. Therefore before in the foil interior items should be carefully cleaned. 
 13, not a large number of Mobile Location 
 Chai Wan paper, sprayed water want to paste the glass, as accurately as possible, if the paste up malposition, and then move touches the glass all around the object or plasticine tank sand. 
 Fourth, to catch water 
 Just posted up an action to catch the water, the water from top to bottom to catch, from right to left or from left to right, but not to catch a lot of water from bottom to top, non-disposable water completely out of order to avoid water backflow driven sand off. 
 Fifth, to forgo the opened 
 The paper has been affixed to the glass, try not to set off, set off the more the number, the more sand, particles and other impurities. 
 16, glass cleaning is not clean 
 Some cars demolition of the old ones, the residual adhesive should be thoroughly clean any label, the debris should really clean up, or the technology no matter how useless. 
 Seventeen, the water did not push the dry 
 Wiper is the final action of the stickers, and more than 80% of the general industry unable to scrape out most of the water, is often the case of winter volatile slow month, not dry, rapid evaporation of large amounts of water in the summer would leave the bubble, must be more hard scraping gum force in order to catch the water, note that any omission. 
 18., Air with water being pumped into the sand 
 The old car the mud trough around the rubber inside the hidden invisible sand dust, paper co-up some glass curvature of large, water gap formed between the glass and film, if rapid water out of the sand will continue to be pumped into the paper. 
 Ninth, windows 
 Used cars rarely will be affixed to perfect, especially the adhesive agent is loose, the sand will be more, then use newspaper or wallpaper cover audio, pasted at the round about, shave, clean water will prevent the majority of sand, The Wiper way should be correct.
