Although the plastic template over 30 years, but so far there is still no industry in product technology standard, most manufacturers do not have corporate standards. In recent years, with the plastic template in building construction applications more and more, getting better and better market prospects, many plastics production enterprises to enter the ranks of the production of plastic template. Eligible products must have a plastic template specific gravity, absorption rate, tensile strength, bending strength, elastic modulus, impact strength, surface wear, deformation temperature, shrinkage, flame resistance and aging resistance and other technical indicators, and to meet construction template requirements. But now most of the technical performance of the enterprise architecture templates do not understand the requirements, product samples provided no product specifications and test reports, or indicators project, no specific indicator data, this product will undoubtedly bring some users use problems.
Construction template size specifications to meet the construction and building module requirements, currently various plastic template companies are not the same size specifications, different specifications very messy. Many companies offer products not meet the requirements Size construction template, template length dimension if the company offers is "any length", thickness in a range from "1 to 10 cm" and so on.
Therefore, it should be developed as soon as possible industry standard plastic template proposed various technical indicators and sizes of unified standard template in order to promote the healthy development of the plastic template.
Generally not resolved before the performance deficiencies of plastic template
Plastic with water, acid and alkali resistance, plasticity and other characteristics. At the same time, there is less strength and stiffness, heat resistance and poor aging resistance, thermal expansion coefficient and other weaknesses.
