Chaw tsim tshuaj paus cov nqe lag luam zoo nkauj oxalic acid CAS: 144-62-7
Oxalic acid yog ib qho muaj zog dicarboxylic kua qaub tshwm sim nyob rau hauv ntau cov nroj tsuag thiab zaub, feem ntau yog nws cov calcium lossis cov ntsev potassium. Oxalic acid yog qhov tsuas ua tau compound nyob rau hauv uas ob pawg carboxyl tau koom ncaj qha; Vim li no oxalic acid yog ib qho ntawm cov organic muaj zog tshaj plaws. Tsis zoo li lwm cov roj carboxylic acids (tsuas yog formic acid), nws yog qhov yooj yim oxidized; Qhov no ua rau nws muaj txiaj ntsig zoo li tus neeg sawv cev txo tus neeg sawv cev rau kev thaij duab, tshuaj dawb, thiab tus cwj mem raug tshem tawm. Oxalic acid feem ntau yog npaj los ntawm cov cua sov sodium decate ua cov sodium oxaleate thiab kho nrog cov sulfuric acid kom tau txais oxalic acid kom tau dawb oxalic acid.
Kev ua tau zoo ntawm oxalic acid tau zoo nkauj qis nyob rau hauv feem ntau cov nroj tsuag thiab nroj tsuag thiab beet zaub ntsuab los cuam tshuam nrog kev nqus cov calcium cov nroj tsuag kuj muaj.
Nws yog tsim nyob rau hauv lub cev los ntawm metabolism ntawm glyoxylic acid los yog ascorbic acid. Nws tsis yog metabolized tab sis tawm hauv cov zis. Nws yog siv los ua kev tshuaj ntsuam thiab dav dav txo cov neeg saib xyuas tus neeg saib xyuas.Oxalic acid yog ib lub ntuj mites nyob rau hauv cov kob nrog tsis muaj / tus brood, pob, lossis cov pob zeb. Vaporized oxalic acid yog siv los ntawm qee cov beekeepers raws li ib tug kab tshuaj tua kab rau ntawm parasitic varroa mite. -
Chaw tsim tshuaj paus tus nqi Xanthan ntawm cov Gub yog: 11138-66-2
Xanthan ntawm cov pos hniav, tseem hu ua Hanseonggum, yog ib hom microbial exopolysacysacysacysacysacchariver uas yog cov khoom siv carboysa nrog cov khoom siv pob kws ua lag luam (xws li fermentation engineering. Nws muaj qhov txawv txawv, cov dej solubility zoo, ruaj khov rau cua sov thiab cov kua qaub, thiab muaj cov ntsev zoo nrog ntau cov ntsev. Raws li tus neeg saib xyuas tuab, raug tshem tawm tus neeg sawv cev, cov tshuaj khov, tuaj yeem siv tau dav hauv cov zaub mov, yog tam sim no dav dav siv microbial polysaccharide.
Xanthan ntawm cov pos hniav yog lub teeb daj kom dawb hmoov kom dawb hmoov, me ntsis tsw. Soluble hauv dej txias thiab dej kub, nruab nrab kev daws teeb meem, tiv taus khov thiab yaj, insoluble hauv ethanol. Dej txawv, emulsification rau hauv hydrophilic ruaj khov viscous colloid.

Chaw tsim tshuaj paus kom zoo nqe durp muaj qeb cas: 28553-12-0
Dijinionyl phthalate (decp):Cov khoom no yog pob tshab oily kua nrog kev tsw me. Nws yog ib qho khoom siv tseem ceeb heev nrog cov khoom zoo. Cov khoom no yog soluble hauv PVC, thiab yuav tsis precipitate txawm tias siv nyob rau hauv ntau ntau. Volatilization, tsiv teb tsaws chaw thiab tsis muaj tshuaj lom tau zoo dua li DOP (Diocty rwb thaiv tsev, thiab cov khoom siv hluav taws xob zoo, thiab kev ua tau zoo dua li dop. Vim tias cov khoom lag luam tsim los ntawm cov khoom no muaj cov dej tsis kam, cov hluav taws xob tsis tshua muaj txiaj ntsig, yog li siv tau dav hauv qhov khoom ua si ua si, xaim, cable.
Piv nrog dep, lub cev molecular loj dua thiab ntev dua, tsis kam mus tsiv teb siab, anticair zoo, thiab siab dua qhov kub siab kuj. Sib raug zoo, nyob rau hauv tib qho kev mob, cov hliav cov nyhuv ntawm dinp yog me ntsis tsis zoo li dop. Nws yog feem ntau ntseeg hais tias Diav yog ntau lub sijhawm ib puag ncig ua phooj ywg.
DINP has superiority in improving extrusion benefits. Nyob rau hauv cov extrusion ua tej yam, dinop tuaj yeem txo cov qauv viscosity ntawm cov sib xyaw ua ke, txo cov khoom siv tshuab hluav taws xob lossis nce ntxiv cov khoom lag luam (txog 21%). Tsis tas yuav hloov cov qauv tshuaj thiab cov txheej txheem ntau lawm, tsis muaj peev txheej ntxiv, tsis muaj kev noj haus ntxiv, thiab tswj cov khoom zoo.
Dinop yog ib txwm oily kua, insoluble hauv dej. Feem ntau thauj los ntawm cov tankers, me me pob ntawm cov hlau hlau lossis cov ntoo yas tshwj xeeb.
Ib qho ntawm cov ntaub ntawv nyoos raw ntawm dmp -ina (ina nyob hauv lub ntiaj teb tuaj yeem tsim tau, xws li lub tuam txhab kev yeej, Nyiv tus neeg tuam txhab sib tw, thiab South Asian tuam txhab hauv Taiwan. Tam sim no, tsis muaj lub tuam txhab hauv tsev ua rau ina. Txhua tus tuam ntxhab uas ua Dino nyob hauv Suav teb yog txhua yam yuav tsum tau los ntawm kev txawv teb.
