Nws yog qhov tsim nyog rau kev tsim khoom ntawm ntau yamroj hmab O-ringcov ntaub ntawv. Raws li cov roj tsis kam, cov khoom siv tuaj yeem muab faib ua cov roj hmab polar thiab cov roj hmab tsis-polar. Ntawm lawv, polar roj hmab yog roj-resistant roj hmab, tsis-polar roj hmab belongs rau roj-resistant roj hmab. Koj paub ntau npaum li cas txog cov roj tsis kam ntawm cov ntsaws ruaj ruaj ntawm cov khoom sib txawv? Hauv qab no yog cov lus qhia luv luv.
1. Hluav taws kub tsis kam
Ntawm ntau cov ntaub ntawv,FMVQ fluorosilicone roj hmab thiab FKM fluorosilicone roj hmabmuaj kuj zoo kuj rau roj roj. Ntawm lawv, cov nplaim retardant ntawm chloroprene roj hmab thiab chlorinated polyethylene roj hmab tsis zoo, cov nplaim hluav taws xob ntawm chloroprene roj hmab thiab chlorinated polyethylene roj hmab tsis zoo, thiab nplaim hluav taws kub ntawm chlorinated polyethylene roj hmab tsis zoo. Cov nplaim hluav taws kub nyhiab ntawm NBR tsis raug kho thiab yuav hloov nrog kev hloov pauv ntawm cov ntsiab lus propylene. Feem ntau, raws li tus nqi ntawm propylene nce, nws cov nplaim retardancy nce, thiab nplaim retardancy ntawm chlorol roj hmab feem ntau zoo dua li cov roj hmab butadiene.
2. Kev tiv thaiv kev sib xyaw roj
Nyob rau hauv cov nqe lus ntawm kev sib xyaw roj kuj, FMVQ fluorosilicone roj hmab thiab FKM fluororubber muaj kev sib xyaw roj zoo tshwj xeeb. Acrylic roj hmab tsis kam rau cov roj sib tov. Nrog rau qhov nce ntawm propylene cov ntsiab lus hauv NBR cov khoom, qhov sib xyaw ua haujlwm ntawm cov roj hmab yuav raug txhim kho, thiab cov roj hmab fluorine nrog cov ntsiab lus fluorine muaj zog tuaj yeem muaj kev sib xyaw ua haujlwm ruaj khov.
