Application and detection method of ASA film covering degree
When ASA film is applied, in addition to requiring aging resistance, in order to take into account the economic production and processing of commodities, ASA film also tries to take into account accuracy, cover, tensile strength, folding resistance, etc. The following points, that is, the relevant details of ASA film coverage:First, the efficacy of covering degree(1) In the whole process of laminating, it is often necessary to ensure that the ASA film has sufficient coverage, which is to ensure the consistency of the color of the finished product when the background color of the composite plate is slightly fluctuating.(2) If the ASA film coverage is poor, it is easy to cause the color of the goods to be biased due to the fluctuation of the background color, which hurts the appearance of the finished product.Second, covering degree test(1) Check the coverage of the film, according to the flashlight on the back of the ASA film, the film with poor coverage, the light sense is clear and visible, and the film with good coverage can only have a slight sense of light.(2) In addition, it can also be viewed against the outdoor sun, the film with weak coverage can clearly see the halo, and the film with good coverage can not be seen.

The application of ASA material in PVC resin tile
In the production process of synthetic resin tile, there is a very important process - co-extrusion. In this production process, the fluidity of ASA co-extrusion material is matched with the fluidity of PVC base material, as well as the addition amount of water inlet material in PVC base material, the quality of the mold, and the control of temperature. The technical level of the operator and the sense of responsibility have a direct and indirect impact on the uniformity of the PVC tile surface, exposure, scratches, impact resistance, weather resistance and other quality problems.ASA weather-resistant functional film and PVC shingle composite technology and co-extrusion technology, has a great change, completely solve the above factors on the quality of the product, and through the modification technology, in the ASA film and PVC shingle composite does not occur delamination, cracking phenomenon, high temperature resistance, low temperature test peel strength to meet the quality requirements, no film layer separation phenomenon.Our company ASA weathering film, toughness is higher than the market co-extruded ASA material, tensile strength, impact strength is good, therefore, the same PVC tile strength, can greatly reduce the cost of PVC base material, ASA weathering film toughness increased by one percentage point, PVC tile co-extruded cost can be reduced by 20-30 percentage points. The use of high toughness ASA weathering film is one of the effective ways to save costs.

Advantages of ASA weather resistance and UV resistance
ASA is a graft copolymer of acrylic ester, acrylonitrile and styrene, the outer layer of which is the graft polystyrene-acrylonitrile copolymer, referred to as SAN, and the core part of the copolymer is butyl acrylate rubber, referred to as PBA.ASA has super anti-ultraviolet function, used for outdoor injection molding products and direct contact with sunlight, anti-ultraviolet does not fade or yellow.Four advantages of ASA1. ASA has good mechanical and physical properties.2. ASA has strong weather resistance.3. ASA has good high temperature resistance.4, ASA is an anti-static material, can make the surface less dust.If the polymer contains double bonds, the double bonds are easy to be opened by the ultraviolet rays in the sunlight with greater energy intensity, resulting in the deterioration of the aging resistance of the polymer.ASA is the use of acrylic rubber without unsaturated double bonds to replace the butadiene rubber containing unsaturated double bonds in ABS, so not only can resist the degradation, aging, fading caused by ultraviolet irradiation, but also the decomposition or discoloring caused by high temperature in the oxidation process of the atmosphere has a strong guarantee, which greatly improves the anti-aging and weather resistance of the material.According to the test results, the anti-aging performance of ASA is more than 10 times that of ABS.
