Identification of glass sand blasting and the use of protective film

Protective film is also known as tape. Sandblasting protective film refers to a special kind of sand used in the diamond spray to protect the sculpture art glass tape.

Blast protection film generally divided into two kinds: one is oil-free gel off at the end of paper; the other is a plastic water off at the end of paper. Both are composed of three parts: silicon coated release paper, glue (oil gel or water gel), PVC plastic mask.

Blast protection film is a composite plastic protective film of water, mainly for sandblasting carving art glass, the surface protection of other items. That Amin glue series water glue, this glue non-toxic, harmless to human body, is in line with the state of green environment-friendly glue.

Quality requirements for blast protection film can be grouped into three points:

1) First of all asked not to be unglued. After processing in the glass, torn blast protective film, the surface of the processed glass products can not leave some traces of glue and to keep products clean and beautiful.

2) good strength and toughness. Refers to the mask can withstand injection of 6 --- 8 kg Emery's impact, otherwise it will break the breakdown of protective film to be processed objects. 3) appropriate viscosity. Refers to both mask stick together, securely glued to the vitreous on the protected, but also in the blasting process is completed successfully when the do not, through torn off the protective film Cuibao fracture, tear and unnecessary trouble.

4) can be used for computer carving. Computer carving carved glass can save time and labor, is a high-tech trend. This requires the back blast protective film has a certain thickness of the release paper and easy separation. Blast protection film of the color and size can be made with the customer requirements. Common colors are white, yellow, commonly used specifications are broad 45,60,90,10. 5,120 cm, length in meters, according to the requirement to build.

    The quality of blast protection film, a direct impact on working time and product quality, the following talk about how the quality of the protective film were examined.

First, blast protection film coated on PVC plastic mask with silicon release paper test strip, coated glue the mask on the back side of stiffness kneading, the rubber and plastic bonded together closely, and then pull away, pay attention to plastic and the glue between the plastic wire pulled up no more than 0.2 mm (with a wire saw almost no glue), so that the protective plastic film off the possibility of use is minimal.

Second, testing the thickness of PVC mask is also very important. As it relates to the protective film to withstand blast impact. The general level of 9 wire blasting film is appropriate, do flat spray, paint, light carving (carved into the depth of less than 1mm). If you need deep carving (carved into the depth of 1.5mm and above), the thickness of protective film should be a corresponding increase, such as the 13 wire, 15 wire, marble sculpture tends to be used 17 to 22 wire. If deep-carved with flat spray when the film will be breakdown, damage to the object to be processed. Can mask detection of micrometer thickness. Visual alone, not easy to grasp the hand touch, because the diameter of a human hair is about 7-wire, imagine feeling sensitivity is difficult to achieve. In addition, the protective film manufacturers have regular seasons of the points. Winter softer film toughness, paste and strong. Summer film a little rigid, easy to start paving. Final recommendations in the spring and autumn, do not keep the plot too much because of seasons, temperature and humidity, are able to influence the quality of blast protection film, for example: film summer and winter use, easy to appear degumming; summer and winter film will result with the hard and brittle film paste is not strong. Blast protection film should not be exposure, and it is not damp, place the optional ventilated place. Longhua, Shenzhen Everbright far suggested the production of "Everbright Far card" blasting protective film: its features are: -20 ° C the following in the body does not use rigid film, paste and strong, with high temperatures in the 40 ° C without degumming, and expand without deformation. Hand, computer carving can be used.
