Product Description:
(1) Ordinary sodium nitrite: dawb zoo crystals, los yog lub teeb daj.
(2) Cov hmoov qhuav sodium nitrite: dawb siv lead ua, tsis muaj pob, xoob.Lub ntiajteb txawj nqus tshwj xeeb 2.168, tsis muaj ntxhiab tsw, me ntsis ntsev, yooj yim deliquescent, yooj yim soluble hauv dej, melting point ntawm 271 ° C, decomposition kub ntawm 320 ° C, oxidative thiab reductive.Maj mam oxygenated rau hauv sodium nitrate hauv huab cua, yooj yim tsim cov nitrogen tebchaw nrog cov amino pawg ntawm qhov kub thiab txias.
(3) Khoom noj khoom haus qib Sodium nitrite yog dawb los yog daj me ntsis rhombohedral siv lead ua los yog hmoov, molecular mis NaNo2, melting point 271 ° C, me ntsis ntsev, yooj yim rau deliquesce, soluble nyob rau hauv dej, aqueous tov yog alkaline, nyob rau hauv cov huab cua yuav maj mam. oxidized rau hauv sodium nitrate.
Daim ntawv thov:
(1) Feem ntau yog siv los ua raw khoom rau kev tsim nitro tebchaw, azo dyes, thiab lwm yam., mordant rau ntaub dyeing, bleaching tus neeg saib xyuas, raws li zoo raws li rau hlau tshav kub tus neeg saib xyuas, cement thaum ntxov lub zog tus neeg saib xyuas thiab anti-icing neeg sawv cev.
(2) Khoom noj khoom haus qib Sodium Nitrit feem ntau yog siv los ua xim xim hauv kev ua cov nqaij.Nws tau ntxiv rau hauv cov zaub mov raws li kev cai, tab sis kev noj ntau dhau yuav ua rau tib neeg lub cev raug mob.
Pob: 25 kgs / hnab los yog raws li koj thov.
Cia: Khaws ntawm qhov chaw muaj cua, qhuav.
Executive Standard: International Standard.
