4,4′-Diaminodiphenylsulfone/DDS/CAS 80-08-0
4 4 '- diaminodiphenyl sulfone yog ib qho tseem ceeb aromatic sulfone compound refined los ntawm qhov kub siab thiab siab siab ammonification reaction. Nws yog siv rau hauv kev tsim cov polysulfone amide resins thiab lwm yam polymer synthetic materials, nrog rau kev tsim ntau yam acidic azo dyes thiab disperse dyes.
4 4 '- Diaminodiphenylsulfone siv tau ua tus neeg sawv cev rau epoxy resin thiab cov khoom siv rwb thaiv tsev hauv kev lag luam hluav taws xob, cov khoom siv textile, thiab ua tus catalyst. Nws kuj tseem siv tau hauv kev lag luam tshuaj kho mob ruas, herpes zoo li dermatitis, AIDS, thiab lwm yam mob.
Ntim rau hauv 25 kg ib lub nruas los yog raws li cov neeg siv khoom xav tau.
4,4'-Diaminodiphenylsulfone yuav tsum tau kaw thiab khaws cia kom deb ntawm lub teeb. Nws yuav tsum tau khaws cia rau hauv qhov chaw txias thiab qhuav. Khaws cia kom kaw thaum tsis siv.
Kev ntsuas kev pab thawj zaug
Yog koj kov qhov muag: Nqa koj ob lub qhov muag thiab yaug nrog dej ntws los yog kua ntsev. Nrhiav kev kho mob. Yaug kom huv si nrog dej. Nrhiav kev kho mob.
Kev Ua Pa: Sai sai tawm ntawm qhov chaw thiab tsiv mus rau qhov chaw uas muaj cua ntshiab. Tsis txhob ua kom txoj hlab pa tsis txhob raug thaiv. Yog tias ua pa nyuaj, muab oxygen rau. Yog tias ua pa tsis tau, ua pa cuav tam sim ntawd. Nrhiav kev kho mob.
Kev Noj: Haus dej sov ntau thiab ua kom ntuav. Nrhiav kev kho mob.
