Cov khoom siv
1.Nws yog tsuas yog siv los ua zaub mov preservative, thiab kuj siv los ua tshuaj, dyes, thiab lwm yam.
2.Siv nyob rau hauv kev lag luam kws tshuaj thiab cog noob caj noob ces kev tshawb fawb, kuj siv raws li dye intermediate, fungicide thiab preservative Antiseptic; antimicrobial tus neeg sawv cev.
3.Sodium benzoate kuj yog ib qho tseem ceeb acid-hom zaub mov preservative. Thaum siv, nws tau hloov mus rau hauv daim ntawv zoo ntawm benzoic acid. Thov xa mus rau benzoic acid rau thaj tsam thiab kev siv ntau npaum li cas. Tsis tas li ntawd, nws tseem tuaj yeem siv los ua cov khoom noj khoom haus.
4.Cov khoom no yog siv los ua zaub mov additive (preservative), fungicide nyob rau hauv kev lag luam kws tshuaj, ib tug mordant nyob rau hauv kev lag luam dyeing, ib tug plasticizer nyob rau hauv kev lag luam yas, thiab ib tug intermediate nyob rau hauv organic synthesis xws li naj hoom.
5.Siv raws li ib tug solubilizer rau ntshav bilirubin kuaj, khoom noj khoom haus additive (preservative), bactericide nyob rau hauv kev lag luam kws, mordant nyob rau hauv lub lag luam dyeing, plasticizer nyob rau hauv cov yas kev lag luam, thiab kuj siv raws li ib tug intermediate nyob rau hauv organic synthesis xws li asperfume lub cev.
Ntim Thiab Cia
Pob:packed nyob rau hauv dej-pov thawj yas woven hnab, 25kg ib lub hnab los yog raws li koj xav tau.
Lus Cim: Cov tshuaj muaj pes tsawg leeg thiab qhov loj tuaj yeem ua kom zoo los ntawm cov neeg siv khoom xav tau
Cia:
Khaws lub thawv kaw kom nruj rau hauv qhov chaw qhuav, txias thiab zoo-ventilated. Cia sib nrug ntawm cov khoom ntim khoom noj lossis cov khoom siv tsis sib xws.
Kev Tiv Thaiv Kev Nyab Xeeb
Kev ceev faj rau kev nyab xeeb
TSIS qhib nplaim taws. Kaw qhov system, plua plav tawg-pov thawj cov khoom siv hluav taws xob thiab teeb pom kev zoo. Tiv thaiv kom tsis txhob muaj plua plav. Tuav nyob rau hauv qhov chaw zoo ventilated. Hnav khaub ncaws tiv thaiv kom haum. Tsis txhob kov ntawm daim tawv nqaij thiab qhov muag. Tsis txhob tsim cov hmoov av thiab aerosols. Siv cov cuab yeej tsis muaj teeb meem. Tiv thaiv hluav taws los ntawm electrostatic tawm chav.
