In terms of acid and alkali resistance, the acid and alkali resistance of PVC sheet is better than that of PP sheet, but the texture is more brittle and hard, resistant to ultraviolet radiation, can withstand climate changes for a long time, is not flammable, and has light toxicity. However, the PP sheet is not UV proof, and it will change color if exposed to sunlight for a long time.
PP sheet is a commonly used sheet in our lives, and many times we need to process it in plastic. Which method to choose depends on the technical conditions of the PP sheet parts and different usage requirements.
Mewn cynhyrchu gwirioneddol, er bod siâp, maint a defnydd achlysuron y ffitiadau pibell yn wahanol, mae ei weithdrefnau prosesu yr un peth ac fe'u rhennir yn sawl cam. Gellir gwireddu pob gweithdrefn brosesu trwy wahanol ddulliau prosesu. O'i gymharu â phrosesu plastig dalen, er bod ganddynt lawer o debygrwydd o ran priodweddau anffurfio, nodweddion anffurfio, ac ati, mae yna lawer o debygrwydd rhyngddynt, ond o ran dulliau proses, anawsterau proses i'w datrys, ac offer Mae gwahaniaethau mawr mewn dyluniad strwythurol, dewis paramedr proses, a mesurau proses a gymerwyd i atal diffygion ansawdd cynnyrch, ac mae yna wahanol resymau.
