Izakhiwo

Impushana emhlophe.Akukho phunga kodwa kunambitheka okubabayo.Incibilika ku-acetone, utshwala, ayincibiliki ku-benzene, uphethiloli namanzi.

Isicelo

I-antioxidant yesibili engangcolisi ye-NR, CR, SBR, NBR ne-EPR njll. Isebenza kahle kakhulu ngokumelene ne-oxidation yokushisa ihlanganiswe ne-amine.

Iphakheji

25kg kraft paper bag.

Isitoreji

Umkhiqizo kufanele ugcinwe endaweni eyomile futhi epholile enomoya omuhle, ukugwema ukuchayeka komkhiqizo opakishiwe elangeni eliqondile.Ukufaneleka kweminyaka emi-2.

Isandiso solwazi oluhlobene

1.Ngokufana ne-antioxidant MB, ingusawoti we-zinc ongasetshenziswa ngokuqondile ngaphandle kokuguga futhi unomphumela wokubola kwe-peroxides.Lo mkhiqizo unokumelana nokushisa okuhle kakhulu.Uma ixubene ne-imidazole namanye ama-antioxidants, inomphumela wokuvikela emonakalweni wethusi.Ingasetshenziswa njenge-thermosensitizer eyisizayo ye-latex foam compound ukuze uthole imikhiqizo yegwebu enegwebu elilinganayo, futhi njenge-ejenti ye-gelling yesistimu ye-latex.

2. Wenziwa kanjani umkhiqizo:

(1) Ukwengeza isixazululo sikasawoti we-zinc oncibilika emanzini esixukwini esinamanzi sikasawoti wensimbi ye-alkali ye-2-mercaptobenzimidazole ukuze siphendule;

(2) Ngokusebenzisa i-o-nitroaniline njengento eluhlaza, i-o-phenylenediamine ikhiqizwa ngokuncishiswa, bese isabela nge-carbon disulfide kusixazululo se-sodium hydroxide ukuze kukhiqizwe i-2-mercaptobenzimidazole sodium.Ngemva kokucwenga, usawoti we-sodium uyancibilika emanzini, futhi i-zinc aluminide yengezwe esixazululweni sayo esinamanzi.

3.Iphuzu lokubola lingaphezulu kuka-270 ℃.

    • Bhala umyalezo wakho lapha futhi usithumelele wona
