PP, tseem hu ua polypropylene, yog ib qho polymer ua los ntawm polypropylene ntxiv rau alkene cov tshuaj tiv thaiv, yog cov khoom siv dawb, pob tshab thiab lub teeb pom kev zoo.Cov tshuaj formula yog (C3H6) x, ntom yog 0.89-0.91g / cm3, flammable, melting point 165 ℃, softening ntawm 155 ℃, siv kub ntau yog -30 ~ 140 ℃.Nyob rau hauv 80 ℃ tuaj yeem tiv thaiv corrosion ntawm acid, alkali, ntsev kua thiab ntau yam organic solvents, tuaj yeem decomposed nyob rau hauv cov nyhuv ntawm kub thiab oxidation.Cov pp bristles yog ua los ntawm polypropylene, uas tsis tshua muaj kev hloov pauv, hnav-tiv taus thiab tsis tshua muaj siab dua pbt, thiab yog li siv ntau qhov txhuam txhuam qis.

Txawm hais tias pp bristles pheej yig heev, lawv tuaj yeem siv los tshem tawm cov kab hluav taws xob, vim li cas?Vim tias pp nws tus kheej yog hluav taws xob, yog tias ua ke nrog cov khoom siv hluav taws xob zoo, nws yuav yog ib qho zoo rau kev thaiv qhov tam sim no.
