PPH yeeb nkab yog ib hom tshiab ntawm cov yeeb nkab, feem ntau hu ua random copolymer polypropylene yeeb nkab, nws kuj yog ib qho ntawm cov kav dej loj hauv khw. PPH yeeb nkab belongs rau nruab nrab ntom polyethylene yeeb nkab, nws cov khoom tseem ceeb yog polyethylene, uas muaj cov nram qab no zoo.
Ib qho, acid thiab alkali tsis kam
PPH yeeb nkab muaj zog acid thiab alkali tsis kam, uas yuav tsis cuam tshuam rau qhov zoo ntawm cov yeeb nkab thiab yuav tsis muaj tshuaj tiv thaiv nyob rau hauv tus txheej txheem ntawm kev siv. Yog li ntawd, nws tsis yooj yim rau corroded los yog scaled nyob rau hauv tus txheej txheem ntawm kev siv. Sab hauv ntawm cov yeeb nkab yog du thiab tsis muaj av, xeb, kab mob thiab lwm yam kev cuam tshuam rau dej zoo tshwm sim.
Thib ob, kev ua haujlwm zoo rwb thaiv tsev
PPH yeeb nkab rwb thaiv tsev kev ua tau zoo, feem ntau vim hais tias PPH yeeb nkab rau random copolymer polypropylene yeeb nkab, nws tus kheej muaj thermal conductivity thiab siab thermal conductivity, yog li cov phab ntsa ntawm cov yeeb nkab yog tsis yooj yim los tshwm scaling tshwm sim.
