Product Description:
Muaj sodium metabisulfite yog siv rau hauv kev luam ntawv thiab dyeing, organic synthesis, luam ntawv, tawv tanning, tshuaj thiab lwm yam sectors.
Daim ntawv thov:
1. Siv raws li chromatographic reagent, preservative thiab txo tus neeg sawv cev nyob rau hauv dyestuff thiab tshuaj industries;
2. Siv los ua bleaching agent, preservative, thinning agent, antioxidant, xim tiv thaiv thiab preservative hauv kev lag luam khoom noj khoom haus.
3. Kev lag luam tshuaj rau kev tsim cov tshuaj chloroform, benzyl cawv thiab benzaldehyde. Roj hmab kev lag luam yog siv los ua coagulant. Kev lag luam luam ntawv thiab dyeing yog siv los ua paj rwb bleaching thiab dechlorinating tus neeg saib xyuas thiab paj rwb refining pab. Kev lag luam tawv tawv rau kev kho tawv nqaij, tuaj yeem ua rau tawv nqaij mos, tag nrho, tawv, tsis muaj dej, folding, hnav-tiv taus thiab lwm yam. Nws yog siv hauv kev lag luam tshuaj rau kev tsim cov hydroxyvanillin thiab hydroxylamine hydrochloride. Kev lag luam yees duab ua tus tsim tawm, thiab lwm yam.
4. Kev kho dej: Sodium metabisulfite yog ib qho kev txo qis, uas yog siv los kho cov chromium-muaj cov dej khib nyiab hauv cov dej phwj tuaj.
Pob:25 kgs / hnab los yog raws li koj thov.
Cia:Khaws ntawm qhov chaw ventilated, qhuav.
