Polyisobutylene (PIB) yog cov xim tsis muaj xim, tsis muaj ntxhiab, tsis muaj tshuaj lom los yog cov khoom siv ib nrab nrog cov cua kub zoo, oxygen, ozone, huab cua, UV, acid thiab alkali tsis kam thiab lwm yam tshuaj lom neeg. Nws tuaj yeem siv rau hauv cov roj nplua nyeem. Nws muaj kev siv tseem ceeb hauv cov khoom siv ntxiv, tom qab ua tiav ntawm cov ntaub ntawv polymer, tshuaj thiab tshuaj pleev ib ce, khoom noj khoom haus additives, thiab lwm yam ntaub ntawv tshuaj.
PIB fuel additives yog dab tsi?
Polyisobutylene (PIB)feem ntau yog siv rau hauv cov roj additives vim nws zoo heev tsis kam rau thermal thiab oxidative kev nyuaj siab. PIB txhim kho kev ua tau zoo ntawm cov roj los ntawm kev txhim kho cov khoom xws li lubricity thiab stability, tshwj xeeb tshaj yog nyob rau hauv huab cua txias. Cov additives no muaj txiaj ntsig tshwj xeeb hauv cov cav, uas lawv pab tiv thaiv kev tso nyiaj thiab txo kev sib txhuam, thaum kawg txhim kho efficiency thiab lifespan ntawm lub cav qhov chaw. Tsis tas li ntawd, PIB tuaj yeem sib xyaw nrog cov tshuaj hydrophobic, ua rau muaj kev ua tau zoo ntawm cov roj tag nrho hauv cov roj av thiab diesel xyaw.
