Nws yog ib qho tseem ceeb raw khoom rau synthesized fiber, gooey, tshuaj, tshuaj tua kab thiab dyes, thiab kuj yog ib tug zoo organic hnyav.Nws yog dav siv nyob rau hauv xws industries xws li yas, rubbers thiab luam ntawv thiab lwm yam. Manufacturing
ntawm acetic anhydride, vinyl acetate;Cov khoom siv dav siv hauv cov khoom siv hluav taws xob, dyes, celluloseacetate, tshuaj, hauv-socicides, textile printing, yees duab zaj duab xis thiab coagulating roj hmab latec.
uanity> 25 kilograms, nyob rau hauv peb siv ob lub hnab resealable zip thiab sab nraud nrog txhuas ntawv ci hnab LOSSIS loj dua ob lub hnab ntim tsiaj rau 25kgs hauv ntau ces ntim rau hauv nruas rau shipping.
Thov hu rau peb kom paub meej ntxiv yog tias koj muaj lus nug!
Daim ntawv thov: Kev tsim cov yas acetate, acetic anhydride, acetic ester, acetate, ethyl cellulose thiab chloro acetic acid.Nws tseem tuaj yeem siv rau hauv thaj chaw ntawm cov khoom siv hluavtaws, cov neeg sawv cev sib txuas, chaw muag tshuaj, ferilizer thiab dyeing raw khoom, raws li hnyav nyob rau hauv cov yas, roj hmab thiab luam ntawv.
Siv nyob rau hauv dyeing kev lag luam, yas kev lag luam, tshuaj, roj hmab, thiab lwm yam.Resorcinol yog tsuas yog siv rau cov roj hmab adhesives, hluavtaws resins, dyes, preservatives, tshuaj thiab analytical reagent, xws li thawj sab, resorcinol thiab phenol, cresol zoo sib xws, thiab formaldehyde condensation. polymer, tuaj yeem siv ua viscose rayon thiab nylon log tsheb qaum nplaum, kev npaj cov cement, ntoo kua nplaum siv rau cov khoom siv yas thiab hlau, resorcinol yog ntau azo dye, fur dyes intermediates, raw cov ntaub ntawv thiab tshuaj intermediates rau nitrogen base salicylic acid.Phloroglucinol muaj cov kab mob bactericidal thiab tuaj yeem siv los ua cov tshuaj tua kab mob hauv cov tshuaj pleev ib ce thiab tshuaj pleev ib ce thiab tshuaj pleev ib ce. Cov derivative ntawm resorcinol -methyl umbelliferone yog ib qho nruab nrab ntawm cov tshuaj kho qhov muag, trinitroresorcinol yog ib qho detonator detonator, thiab ntau npaum li cas ntawm resorcinol yog siv nyob rau hauv lub Kev tsim cov diphenylketone ultraviolet absorbers.Cov khoom no tuaj yeem ua rau tawv nqaij thiab cov mucous membrane, tuaj yeem nqus tau sai.hla ntawm daim tawv nqaij ua rau cov tsos mob lom.
Nws yog siv nyob rau hauv kev tsim ntawm ntau cov organic tshuaj thiab dyes, thiab yog ib qho nruab nrab ntawm cov plaub hau dyes. Sab nrauv siv tshuaj rau eczema, psoriasis thiab lwm yam kab mob ntawm daim tawv nqaij.In cov tshuaj pleev ib ce kev lag luam, siv nyob rau hauv cov plaub hau zas formulations (raws li ib tug complementary dye). .Phloroglucinol muaj cov kab mob bactericidal thiab tuaj yeem siv ua cov tshuaj tua kab mob.Nws yog ntxiv rau cov tshuaj pleev ib ce thiab tshuaj tawv nqaij pastes thiab tshuaj pleev
Soluble nyob rau hauv dej, ethanol, amyl cawv, yooj yim soluble nyob rau hauv ether, glycerin, me ntsis soluble nyob rau hauv chloroform, carbon disulfide, me ntsis soluble nyob rau hauv benzene.
Siv nyob rau hauv photosensitive zaj duab xis, tshuaj, dyestuff thiab tshuaj fiber kev lag luam
