Chlorinated Polyethylene Has A High Adhesion And Closability

Edit:Weifang Yaxing Chemical Co.,Ltd   Date:Sep 04, 2017

Chlorinated Polyethylene has a high adhesion and closability
        Chlorinated Polyethylene roller coating varieties used in the spray construction, which can easily lead to slow drying and sagging phenomenon. It is caused by improper handling of wood from the surface of the wood. The wood is made up of a lot of cellulose, gum, resin, pigment and fatty acid. These substances cause defects such as falling clouds, shrinkage and floral. In the case of most of the cases, a complete coating consists of a matching primer, intermediate paint and topcoat coating. The primer requires a high adhesion and closability to the substrate, with excellent adhesion to the intermediate paint or finish. The intermediate paint is the transition layer, mainly to increase the coating thickness, strengthen the hiding power, increase the coating on the harmful substances of the anti-penetration ability and strengthen the decorative role of the coating to form a variety of patterns. Topcoat is a direct contact with the outside world, so it is necessary to further beautify the decorative function, but also against the various anti-function.
        Chlorinated Polyethylene is the thickness of the coating. Due to the uneven surface of the concrete deck after the shot blasting, the working principle of the ultrasonic thickness measurement can produce errors. The construction site should be tested with the bond strength. The thickness of the drawn polyurea waterproof coating is measured by the vernier caliper , As the actual thickness of the sprayed polyurea waterproof coating. Vernier caliper measurement pull out the spindle surface polyurea waterproof layer thickness of the number of pass rate of 100%, if not reached, you need to fill the required thickness of the spray.
 Chlorinated Polyethylene has a very good anti-aging, oxidation resistance and temperature resistance and some other properties, but in the process of curing the pores will produce, which is why? Today, Chlorinated Polyethylene manufacturers to answer your questions.
According to reports, taking into account the compatibility of Chlorinated Polyethylene and EPDM rubber, resulting in a large extent due to the vulcanization rate and the impact of the complex, EPDM rubber structure contains a higher saturation Structural units, in the reaction process need to meet the conditions of similar polarity in order to ensure that Chlorinated Polyethylene blends vulcanization time to maintain good diffusion. And Chlorinated Polyethylene is also a high degree of saturation of the polymer, so the process of curing the pores, is the effect of many reasons superimposed.
As the curing agent usually contains acidic substances, in the high temperature state will form hydrochloric acid, and free radicals react, so the formation of pores is inevitable, Chlorinated Polyethylene manufacturers have many years of production and sales experience, look forward to your call consultation.
 Chlorinated Polyethylene processing aids and PVC processing aids the physical properties of different, so the use of different methods, Chlorinated Polyethylene processing additives products are divided into processing modifier and impact modifier. The product used for the purpose of improving the impact properties of plastics is called an impact modifier
Processing Chlorinated Polyethylene processing aids to improve the processing performance of PVC as the main purpose, it is usually methyl methacrylate and methacrylic acid esters and acrylic ester copolymer copolymerization generated. PVC in the processing need to be heated and shear dispersed into a uniform molten state to shape, but the PVC resin itself on the heat and shear force transmission is not strong, plasticization time is longer, the formation of the melt is not uniform, affecting the appearance of products And mechanical properties, when added ACR processing aids, can significantly improve the melt flow of PVC resin, thermal deformation and product surface gloss and other characteristics.
Chlorinated Polyethylene processing aids are usually made from methyl methacrylate in polymerization of alkyl acrylate elastomers and have a "core-shell" structure. The "core" is a class of low cross-linked acrylic rubber polymer, "shell" is good compatibility with PVC methyl methacrylate graft polymer.
