Kev siv ntawm BHT
Butylated Hydroxytoluene, tseem hu ua BHT, yog ib qho tshuaj lom neeg uas tau siv dav los ua cov tshuaj tiv thaiv kab mob hauv ntau yam lag luam. Nws lub luag haujlwm tseem ceeb yog tiv thaiv oxidation thiab degradation ntawm cov khoom uas muaj roj thiab roj, uas tuaj yeem ua rau lwj thiab poob ntawm cov khoom zoo. BHT yog cov hmoov dawb los yog daj me ntsis uas yog insoluble hauv dej tab sis soluble hauv cov rog thiab roj. Nws yog dav siv hauv cov khoom noj, tshuaj pleev ib ce, tshuaj, thiab petrochemical kev lag luam, thiab lwm yam.
BHT kuj tuaj yeem siv rau hauv cov roj lubricating, kev ua haujlwm thib ob thiab roj av, paraffin, roj ntxhia, polypropylene, polyethylene, polystyrene, ABS resin, polyester cob, cellulose, yas ua npuas ncauj ua cov tshuaj tiv thaiv antioxidant.
BHT yog cov tsis muaj kuab paug los tiv thaiv oxidant stabilizer rau tej yam ntuj tso roj hmab, butadiene roj hmab, styrene butadiene roj hmab, neoprene, nitrile roj hmab, butyl roj hmab, isoprene roj hmab, ethylene propylene roj hmab, transformer roj, txhua yam khoom latex, tshwj xeeb tshaj yog xim dawb los yog lub teeb xim. cov.
Vim li cas pub zaub mov xav tau BHT antioxidant?
Pub cia xav tau BHT antioxidant los tiv thaiv oxidation ntawm pub, uas tuaj yeem ua rau rancidity thiab spoilage. BHT (butylated hydroxytoluene) yog ib qho tshuaj tua kab mob antioxidant uas feem ntau siv rau hauv cov tsiaj noj thiab cov tsiaj noj tsiaj los tiv thaiv kev tawg ntawm fatty acids thiab tswj cov khoom noj khoom haus zoo ntawm cov khoom noj. Yog tias tsis muaj cov tshuaj tiv thaiv antioxidant zoo li BHT, pub tuaj yeem ua rancid thiab tsim kom muaj qhov tsis hnov tsw thiab tsw, uas tuaj yeem cuam tshuam rau tsiaj palatability thiab noj. Tsis tas li ntawd, oxidation ntawm cov khoom noj tuaj yeem ua rau muaj kev phom sij xws li dawb radicals thiab peroxides, uas tuaj yeem cuam tshuam kev noj qab haus huv ntawm cov tsiaj. Yog li ntawd, BHT yog ntxiv rau pub raws li kev tiv thaiv kev tiv thaiv kom muaj kev nyab xeeb, zoo, thiab palatability ntawm tsiaj pub.
