Abstract
Description
technical field
[0001] The invention relates to the technical field of building materials, in particular to a low-foaming PVC crust board. Background technique
[0002] PVC crust foam board has excellent corrosion resistance, insulation, and certain mechanical strength; after secondary processing, it can be made into sulfuric acid (hydrochloric acid) tank (barrel box); medical empty needle frame, chemical process frame ; public toilet water tank; various special-shaped products and containers such as templates, decorative panels, exhaust pipes, and equipment linings for processed products. It is an ideal material for chemical industry, building materials, decoration and other industries. PVC crust foam board is also called PVC crust board. Its chemical composition is polyvinyl chloride. It is widely used in passenger cars, train car ceilings, box core layers, interior decoration panels, building exterior wall panels, and interior decoration. Panels, offices, residences, bu...
