Kev ceev faj txog kev thauj mus los: Cov khoom no yog kua, nws yog nruj me ntsis txwv tsis pub sib xyaw nrog oxidant, edible chemicals, alkali, acid anhydride, thiab lwm yam. Thaum lub sij hawm kev thauj mus los, nws yuav tsum tau tiv thaiv los ntawm tshav ntuj, los nag thiab kub.Lub caij ntuj sov kom deb li deb tau thaum sawv ntxov thiab yav tsaus ntuj kev thauj mus los, txhawm rau tiv thaiv tshav ntuj, kev thauj mus los raws li txoj kab uas tau teev tseg, kev nres tsheb yuav tsum nyob deb ntawm qhov hluav taws kub, qhov chaw kub, qhov kub thiab txias.Nws yog nruj me ntsis txwv tsis pub thauj cov khoom nyob rau hauv tib lub tsheb raws li cov edible tshuaj.Thaum thauj los ntawm txoj kev, nws yuav tsum ua raws li txoj kev tau teev tseg thiab tsis txhob nyob hauv thaj chaw nyob thiab cov neeg nyob ze.Nws yog txwv tsis pub plam lawv nyob rau hauv railway tsheb thauj mus los.Cov nkoj ntoo thiab cov cement ships raug txwv nruj rau kev thauj mus los ntau.
P-tert-butylphenol muaj cov khoom siv antioxidant thiab tuaj yeem siv los ua kom ruaj khov rau roj hmab, xab npum, chlorinated hydrocarbons thiab digestive fibers.UV absorbent, tshuaj tua kab, roj hmab, xim thiab lwm yam tshuaj tiv thaiv tawg.Piv txwv li, siv rau polycarbon resin, tert-butyl phenolic resin, epoxy resin, polyvinyl chloride, styrene stabilizer.Tsis tas li ntawd, nws tseem yog cov khoom siv raw ntawm cov tshuaj tua kab, tshuaj tua kab thiab acaricide, tshuaj tsw qab thiab cov nroj tsuag tiv thaiv tus neeg sawv cev.Nws kuj tseem siv tau ua softener, hnyav, additive ntawm dyes thiab xim, antioxidant ntawm lubricating roj, roj demulsifier thiab additive ntawm tsheb roj.
Lwm yam kev siv:
(1) Rau cov roj soluble phenolic resin, cov khoom thiab formaldehyde condensation tuaj yeem tau txais rau ntau lub hom phiaj.Nyob rau hauv chloroprene nplaum sib tov 10-15% ntawm cov khoom, kom tau soluble resin, hom nplaum no tsuas yog siv rau hauv kev thauj mus los, kev tsim kho, pej xeem, khau-ua, thiab lwm yam hauv kev luam ntawv number case, tuaj yeem siv rau kev hloov kho rosin, offset. printing, advanced photogravure thiab hais txog.Nyob rau hauv lub rwb thaiv tsev varnish, yuav siv tau nyob rau hauv coil dip varnish thiab laminate varnish.
(2) Rau polycarbonate ntau lawm, raws li phosgene polycarbonate cov tshuaj tiv thaiv txiav tawm tus neeg sawv cev, ntxiv cov tshuaj 1-3% ntawm cov resin.
(3) Siv rau epoxy resin, xylene resin hloov kho;Raws li polyvinyl chloride stabilizer, surfactant, UV absorber.
(4) Nrog rau cov khoom antioxidant, tuaj yeem siv los ua roj hmab, xab npum, chlorinated hydrocarbons thiab nitrocelluloose stabilizer.Nws tseem yog cov khoom siv raw ntawm cov tshuaj tua kab (tshuaj), acaricide acaride (tshuaj tua kab) thiab cov nroj tsuag tiv thaiv, tshuaj tsw qab, hluavtaws cob, thiab tseem tuaj yeem siv ua softener, hnyav, dye thiab xim additive.Nws kuj tseem siv tau los ua cov khoom xyaw ntawm demulsifier rau roj teb thiab ntxiv rau cov roj tsheb.
