Cov khoom
Dawb hmoov.Tsis muaj ntxhiab tab sis saj iab.Soluble nyob rau hauv acetone, cawv, insoluble nyob rau hauv benzene, roj av thiab dej.
Daim ntawv thov
Ib qho non-staining Secondary antioxidant rau NR, CR, SBR, NBR thiab EPR thiab lwm yam. Tshwj xeeb tshaj yog zoo tiv thaiv tshav kub oxidation ua ke nrog amine.
Pob
25kg kraft ntawv hnab.
Cia
Cov khoom yuav tsum tau muab cia rau hauv qhov chaw qhuav thiab txias nrog qhov cua zoo, tsis txhob raug cov khoom ntim rau hauv tshav ntuj ncaj qha.Lub sijhawm siv tau yog 2 xyoos.
Cov ntaub ntawv txuas ntxiv
1.Ib yam li antioxidant MB, nws yog zinc ntsev uas tuaj yeem siv ncaj qha yam tsis muaj kev laus thiab muaj cov nyhuv decomposing peroxides.Cov khoom no muaj kev tiv thaiv zoo heev thaum tshav kub kub.Thaum sib xyaw nrog imidazole thiab lwm yam tshuaj antioxidants, nws muaj kev tiv thaiv kev puas tsuaj rau tooj liab.Nws tuaj yeem siv los ua ib qho kev pabcuam thermosensitizer ntawm latex foam compound kom tau cov khoom ua npuas ncauj nrog cov npuas dej, thiab kuj yog ib tus neeg sawv cev ntawm latex system.
2.Qhov khoom ua li cas:
(1) Ntxiv cov dej-soluble zinc ntsev tov rau aqueous tov ntawm alkali hlau ntsev ntawm 2-mercaptobenzimidazole rau cov tshuaj tiv thaiv;
(2) Siv o-nitroaniline ua cov khoom siv raw, o-phenylenediamine yog tsim los ntawm kev txo qis, thiab tom qab ntawd ua rau cov pa roj carbon disulfide hauv cov tshuaj sodium hydroxide los tsim 2-mercaptobenzimidazole sodium.Tom qab refining, sodium ntsev yog yaj nyob rau hauv dej, thiab zinc aluminide yog ntxiv rau nws aqueous tov.
3.Qhov decomposition point yog siab tshaj 270 ℃.
