Taw qhia rau cov khoom siv polymer uas siv hauv cov roj av

Hauv kev lag luam roj av, feem ntau siv cov ntaub ntawv polymer muaj xws li hauv qab no:

1. Polyethylene (PE): Polyethylene yog cov khoom siv thermoplastic uas muaj cov tshuaj tiv thaiv zoo heev thiab cov khoom siv hluav taws xob zoo, thiab yog siv dav hauv cov roj av cia tank, roj kav dej, cov khoom siv tshuaj lom neeg thiab lwm yam kev lag luam.

2. Polyvinyl chloride (PVC): PVC yog cov khoom siv yas dav siv rau kev ua kua thiab kev thauj mus los. Hauv kev lag luam roj av, PVC yog siv los tsim cov khoom siv xws li cov kav dej, li qub thiab twj tso kua mis.

3. Polytetrafluoroethylene (PTFE): PTFE yog cov khoom siv polymer nrog cov tshuaj tiv thaiv zoo heev thiab tsis tshua muaj coefficient ntawm kev sib txhuam, thiab feem ntau yog siv rau hauv kev lag luam roj av rau txheej txheej sab hauv ntawm cov kav dej, tso tsheb hlau luam thiab lwm yam khoom siv.

4. Polystyrene (PS): Polystyrene yog ib hom yas uas muaj zog txhua yam thiab muaj kev cuam tshuam thiab siv rau hauv kev lag luam roj av rau kev tsim cov kav dej, li qub, cov khoom siv tshuaj, thiab lwm yam.

5. Polyamide (PA): Polyamide yog ib qho tseem ceeb engineering yas nrog zoo heev kub tsis kam, corrosion kuj thiab tsis tshua muaj coefficient ntawm kev sib txhuam, thiab feem ntau yog siv nyob rau hauv cov roj av kev lag luam los tsim gaskets, ceev, washers, thiab lwm yam.

6. Styrene-butadiene-styrene copolymer (SBS): SBS yog ib qho elastomer uas muaj zog tensile zoo heev thiab tsis kub-kub dabtsi yog khoov zog, thiab yog dav siv nyob rau hauv cov roj av sector rau waterproofing txheej ntawm txoj kev thiab txuas hniav thiab lub hauv paus nres coatings, thiab lwm yam.
