Kev piav qhia:
Phosphorus trichloride, PCl3, yog ib yam kua ntshiab, tsis muaj xim, ua pa taws, thiab ua rau xeb. Nws lwj sai sai hauv huab cua noo thiab muaj qhov kub npau li ntawm 168°F (75°C). PCl3 lwj rau daim tawv nqaij thiab cov ntaub so ntswg thiab ua rau dej ua rau hydrochloric acid. TLV yog 0.2 ppm, thiab IDLH yog 50 ppm hauv huab cua. Tus lej UN plaub tus lej yog 1809. Lub npe NFPA 704 yog kev noj qab haus huv 4, kev kub hnyiab 0, thiab kev ua haujlwm 2. Ntu dawb ntawm qab ntawm lub pob zeb diamond muaj W nrog ib kab txiav hla nws, qhia txog kev ua haujlwm ntawm dej. Kev siv tseem ceeb yog siv rau kev tsim cov tshuaj tua kab organophosphate, cov roj av ntxiv, thiab cov xim zas; ua tus neeg sawv cev chlorinating; ua tus catalyst; thiab hauv kev ua tiav cov ntaub. Cov tshuaj xeb uas sib cuag nrog tshuaj lom yuav tsim cov pa tshuaj lom thaum cov tshuaj lom lwj. Thaum teb rau qhov xwm txheej uas muaj cov tshuaj lom, qhov lom ntawm cov pa roj yuav ua rau cov neeg ua haujlwm txhawj xeeb ntau dua li qhov xeb. Thaum cov kua qaub cyanide kov cyanide, cov pa hydrogen cyanide, uas muaj tshuaj lom heev, nrog TLV ntawm 10 ppm hauv huab cua, raug tsim tawm.

Kev Siv
Phosphorus trichloride yog siv los npaj phosphine thiab lwm yam phosphorus compounds; siv thaum lub sijhawm electrodeposition ntawm hlau ntawm roj hmab thiab rau kev ua cov tshuaj tua kab, surfactants, roj av additives, plasticizers, dyestuffs, textile finishing agents, germicides, tshuaj kho mob, thiab lwm yam tshuaj.
Phosphorus trichloride yog siv los ua tus neeg sawv cev chlorinating; ua ib qho nruab nrab hauv kev ua cov roj av additives, dyes, surfactants, thiab tshuaj tua kab; hauv kev tsim cov phosphorus pentachloride thiab phosphorus oxychloride; thiab ua ib qho catalyst.
Phosphorus trichloride yog ib qho tseem ceeb hauv kev tsim cov tshuaj tua kab, tshuaj tua nroj, thiab cov tshuaj tua kab organophosphorus nrog rau lwm yam tshuaj xws li phosphoryl chloride, phosphorus pentachloride, thiophosphoryl chloride, thiab phosphonic acid. Nws kuj tseem siv rau hauv kev tsim cov tshuaj surfactants hluavtaws, phosphites, roj av additives, flame retardants, silver polish, thiab tsim cov hlau iridescent deposits.
Ntim thiab Xa Khoom
300KG / Nruas los yog raws li cov neeg siv khoom xav tau.
Nws tuaj yeem xa los ntawm dej hiav txwv thiab huab cua
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
