Nkag siab txog Cov Khoom Siv Tshuaj ntawm Tetrachlorophthalic Anhydride
Tetrachlorophthalic anhydride (Tetrachlorophthalic anhydride luv luv) yog cov hmoov dawb crystalline feem ntau siv rau hauv kev sib txuas ntawm dyes thiab resins. Nws yog hygroscopic heev thiab maj mam hydrolyzes thaum sib cuag nrog dej, yog li yuav tsum tau saib xyuas tshwj xeeb kom tsis txhob ya raws kev puas tsuaj thaum thauj. Hom tshuaj no feem ntau muab faib ua cov tshuaj corrosive thiab ua rau khaus rau cov hlau thiab tawv nqaij.
Cov ntsiab lus tseem ceeb ntawm Thauj Ntim
Ntim Qeb: Raws li nws cov corrosiveness thiab toxicity, tetrachlorophthalic anhydride feem ntau siv Class III ntim.
Kev xaiv lub thawv: Muab ob npaug -polyethylene hnab ntim nrog fiberboard nruas yog pom zoo, los yog galvanized hlau nruas lined nrog cov hnab yas.
Sealing Requirements: Tag nrho cov ntim yuav tsum yog airtight kom tsis txhob nkag ntawm huab cua ntub.
UN Code thiab Transport Marking
UN code rau cov khoom no yog UN3261, belongs rau Class 8 corrosive tshuaj. Cov tsheb thauj mus los yuav tsum tau muab cov ntawv cim corrosive (dawb tom qab nrog cov ntawv dub, ib nrab dub, qis ib nrab dawb), thiab nws yuav tsum tau muab cais tawm ntawm cov zaub mov, oxidizers, thiab lwm yam. Thaum lub caij ntuj sov tsheb thauj mus los, nws raug nquahu kom tswj qhov kub hauv lub tsheb qis dua 30℃thiab zam kom tsis txhob raug tshav ntuj ntev.
