As the most important core part of WPC floor, its production is controlling the lifeline and future of this kind of floor. The biggest difficulty for manufacturers is the uniformity of density and the dimensional stability after heating. At present, the quality of the substrate can be found in the market is uneven, and the most common test we can usually do is to test the stability of the substrate by heating. The test requirements of international multinational enterprises are usually 80 ℃ and the test time is 4 hours. The measured project standards are: deformation ≤ 2mm, longitudinal shrinkage ≤ 2%, transverse shrinkage ≤ 0.3%. However, it is extremely difficult for WPC core production to achieve both standard products and cost control, so most enterprises can only improve the product density to achieve stability. The ideal core density is in the range of 0.85-0.92, but many enterprises increase the density to 1.0-1.1, resulting in high cost of finished products. Some enterprises produce non-conforming core regardless of product stability.
Xinghua Zhengfu Plastic Industry Co., Ltd. is a professional manufacturer engaged in R & D, production and sales of high-tech environmental protection flooring and wallboard products. Its predecessor was Wuxi Zhengshan Industrial Co., Ltd., which was established in 1993. Later, due to the relocation of the government, it moved to Laoxu industrial concentration area in Xinghua City. Zhengshan brand PVC floor developed by the company is a new type of energy-saving environmental protection material.
At present, the company covers an area of 135 mu, with a construction area of 35000 m2 and a total investment of 160 million yuan. It plans to build a large domestic production base of PVC decorative materials.
The company's products include: indoor series, mainly including stone plastic floor, PVC wood plastic wallboard, ceiling, space partition, shutter curtain, door and window profile, simulated marble line, etc.; outdoor series, mainly including floor, billboard, garden landscape, etc. The monthly production capacity of flooring products can reach 150000 m2.
In addition to the nationwide sales, the products are also exported to more than 10 countries and regions, including the United States, Canada, Spain, Belgium, the United Kingdom, Russia, Denmark, the Middle East and Southeast Asia, and are gradually expanding overseas markets.
