PIB material?
Polyisobutylene pibyog lub polymer ntawm isobutene, cov khoom tseem ceeb ntawm butyl roj hmab. Ib qho ntawm cov khoom tseem ceeb tshaj plaws yog nws cov solubility hauv dej. Cov cuab yeej no ua rau cov khoom lag luam tuaj yeem siv tau thoob ntiaj teb polymer, rau ntau yam kev lag luam sib txawv.
PIB fuel additives yog dab tsi?
PIB (polyisobutylene) fuel additivesyog cov tshuaj polymerized uas pab txhim kho kev ua haujlwm ntawm cov roj xws li roj av. Lub luag haujlwm tseem ceeb ntawm cov additives no yog ua raws li kev tswj hwm cov neeg ua haujlwm tso nyiaj, tiv thaiv kev tsim cov deposits hauv lub cav, uas tuaj yeem txhaws cov khoom tseem ceeb xws li roj injectors thiab intake valves. Los ntawm kev txhim kho cov roj ntws thiab kev sib xyaw kom zoo, PIB additives pab tswj lub cav ua haujlwm thiab ua haujlwm ntev.
PIB additives feem ntau yog siv nyob rau hauv cov pa thiab kev ua tau zoo fuels los xyuas kom meej lub cav ua haujlwm du thiab txo qis kev tu lub cav.
