Isopropyl Cawv Muaj Kev Siv Dej
Solvent Applications:
Raws li ib qho qis -toxicity hnyav, 99.9% Isopropyl Cawv yog dav siv rau diluting coatings (xws li nitrocellulose thiab amino xim), inks, thiab adhesives. Nws tuaj yeem yaj sai sai ntawm cov resins, roj, thiab lwm yam khoom thiab tawm tsis muaj qhov seem tom qab evaporation.
Hauv kev lag luam hluav taws xob, IPA yog siv los ntxuav lub rooj tsav xwm hluav taws xob thiab cov semiconductor chips, tshem tawm cov roj saum npoo av thiab cov khoom siv hluav taws xob zoo yam tsis muaj kev puas tsuaj hluav taws xob.
Chemical Intermediate:
99.9% Isopropyl Cawv yog ib qho tseem ceeb raw khoom rau kev tsim acetone (ntawm dehydrogenation), isopropylamine (ib nrab nyob rau hauv organic synthesis), thiab isopropyl esters (xws li isopropyl acetate, siv nyob rau hauv fragrances thiab coatings). Nws kuj tseem siv tau los ua cov roj av ntxiv kom muaj nuj nqis octane, txhim kho kev sib xyaw ua ke, thiab txo qis emissions.
