Ntxiv mus, lub tuam txhab tseem tshwj xeeb ntawm nws cov neeg sib tw vim nws cov qauv zoo tshaj plaws hauv kev tsim khoom, thiab nws txoj kev ua haujlwm zoo thiab kev ywj pheej hauv kev txhawb nqa kev lag luam.
Pyrogallol CAS 87-66-1yog siv lead ua dawb tsis muaj ntxhiab. Nws saj iab. Kev raug cua thiab lub teeb hloov mus ua xim grey. Kub qeeb qeeb thiab pib sublimate. Melting point 133-134 ℃, boiling point 309 ℃, qhov ceev txheeb ze 1.453, refractive index 1.561. Yaj hauv dej, ethanol, ether, me ntsis yaj hauv benzene, chloroform, carbon disulfide. Thaum raug cua, xim ntawm cov kua dej tsaus ntuj, thaum xim ntawm nws cov kua caustic hloov pauv sai dua.

1. Pyrogallolsiv rau kev npaj cov hlau colloidal kua, xim tawv, dyeing thiab etching plaub, plaub hau, thiab lwm yam;Pyrogallolkuj tseem siv tau ua tus tsim zaj duab xis, tus duab infrared thermosensitive, tus polymerization inhibitor ntawm styrene thiab polystyrene, tus neeg sawv cev nruab nrab ntawm tshuaj thiab dyes, thiab tus neeg sawv cev analytical.
2. Pyrogallol feem ntau yog siv rau hauv kev tsim cov tshuaj developer, polymerization inhibitor thiab infrared photographic thermosensitive. Pyrogallol kuj tseem siv ua cov tshuaj nruab nrab ntawm cov tshuaj thiab cov xim zas.
3. Pyrogallol siv ua cov tshuaj reagent, reductant thiab developer
4. Pyrogallol siv rau kev tsom xam thiab kev txiav txim siab ntawm cov pa oxygen, antimony, bismuth, cerium, hlau, molybdenum, tantalum thiab niobium; Siv los nqus cov pa oxygen hauv kev tsom xam roj; Siv rau kev ua xim ntawm nitrite, molybdenum, niobium, titanium, cerium, bismuth, tooj liab, vanadium, hlau, iodate, thiab lwm yam
5. Tus neeg sawv cev ua kom cov hlau sib xyaw. Kev txiav txim siab ntawm bismuth thiab antimony los ntawm kev siv gravimetric. Cov tshuaj reductants ntawm kub, nyiaj, ntsev mercury, phosphomolybdic acid thiab phosphotungstic acid, uas yog siv los nqus cov pa oxygen hauv kev tshuaj xyuas roj.
20kgs/hnab, 25kgs/nruas, 200kg/nruas los yog raws li cov neeg siv khoom xav tau. Khaws cia kom deb ntawm lub teeb ntawm qhov kub hauv qab 25 ℃.
