PP hollow board refers to the extrusion of polypropylene raw material blended with polyethylene raw material through a hollow board production line. The cross section of the board is a lattice shape, so it is also called lattice hollow board. Chinese name PP hollow board Foreign name polypropylene hollow sheet is also known as lattice hollow board field engineering technology table of Contents
Low foaming rigid PVC door and window hollow profile production process China's plastic door and window technology has matured through more than ten years of hard work, but there has been no breakthrough progress in the research work on the production of low-foam PVC hollow profiles by extrusion. Low-foamed rigid PVC hollow profile must have the performance of non-foamed profile, and the cor
Common problems and solutions in the production of PVC profiles System control is the key to ensure the long-term stability of PVC profile quality. It contains 4 items including "formulation quality, process quality, appearance quality, physical and chemical indicators". The first two items are the premise and foundation of the last two items, and are also quality control and technical manageme
(1) First measure the ground temperature of the construction site, if it is lower than 10 ℃, it should not be constructed; (2) 12 hours before and after construction, take necessary measures to keep the indoor temperature above 10 ℃; (3) If the construction is on cement ground, it is necessary to check whether the ground is dry enough; (4) After the construction of the cement, the strength will
