Cia thiab ceev faj
3 5-Diaminobenzoic acid yuav tsum tau muab cia rau hauv lub kaw ntom nti, lub teeb - tiv taus lub thawv ntawm 15-25℃, nyob rau hauv ib qho chaw txias, qhuav thiab zoo- ventilated warehouse kom deb ntawm cov tshav ntuj ncaj qha thiab tshav kub. DABA CAS 535-87-5 yog rhiab heev rau cov dej noo thiab oxidation, yog li cia nws cais tawm ntawm dej, qhov chaw ntub dej, muaj zog acids thiab oxidizing cov neeg ua haujlwm kom tiv thaiv kev degradation zoo.
Thaum tuav, hnav cov tshuaj lom neeg-cov hnab looj tes tiv thaiv, tsom iav thiab lub tsho tiv thaiv, thiab ua haujlwm hauv lub hood kom tsis txhob nqus plua plav thiab qhov muag / qhov muag. Tshem lub thawv tam sim tom qab siv. Kev pov tseg pov tseg nruj me ntsis raws li cov cai tswj kev phom sij hauv zos.
Dab tsi yog qhov txiaj ntsig ntawm kev noj 3 5-Diaminobenzoic acid?
3 5-Diaminobenzoic acid ua lub luag haujlwm tseem ceeb ua lub tsev thaiv hauv kev tsim cov khoom xyaw tshuaj, xws li qee yam tshuaj tua kab mob thiab tshuaj tiv thaiv -cov tshuaj tiv thaiv kab mob, pab txhawb kev txhim kho kev kho mob zoo. Tsis tas li ntawd, DABA CAS 535-87-5 yog siv los tsim cov polyamide resins uas muaj zog adhesion thiab tshwj xeeb dyes nrog lub teeb ruaj khov zoo, txhawb kev tsim cov khoom siv ruaj khov.
