Specification

DBD

Cov nyhuv ntawm DBD tus nqi ntawm cov khoom ntawm lub looj roj hmab tau tshawb xyuas. Cov kev tshwm sim qhia tias qhov sib ntxiv ntawm peptizer DBD rau lub looj tsuam roj hmab txo lub Mooney viscosity ntawm lub hnab roj hmab, thiab ua rau Mooney lub sij hawm qhuab qhia thiab lub sij hawm 90. Nrog rau kev nce ntawm DBD nyob rau hauv cov yas yas, qhov ruaj ntseg yas ntawm cov chaw rubber nce. Loj, carbon black dispersion khees me ntsis lawm, kev hnav tsis taus thiab pheej quab yuam kev ntawm vulcanizate tsis hloov ntau ntau; Thaum tus nqi ntawm DBD ntawm lub peptizer yog 0.05 ~ 0.11 qhov chaw, lub cev nqaij daim tawv ntawm vulcanizate zoo dua.

Cov nyhuv ntawm tartaric acid, stearic acid thiab molten stearic acid ntawm cov khoom ntawm cov roj hmab rov qab thaum tus neeg sawv cev DBD siv los ua ib tus activator tshiab. Cov ntsiab lus pom tau hais tias qhov nce ntawm tartaric acid, stearic acid thiab molten stearic acid, cov ntsiab lus ntawm cov roj hmab txeem rov qab, qhov sib dhos ntawm kev sib tshuam tsis tshua sib zog, Mooney viscosity thiab Mooney viscosity ntau zog, thiab lub zog tensile thawj Thaum tus nqi ntawm tartaric acid thiab stearic acid yog 0.6 feem, qhov kev ua tau zoo dua yog qhov zoo dua; Thaum tus nqi ntawm molten stearic acid yog 0.9 qhov chaw, qhov kev ua tau zoo tshaj yog qhov siab. Nrog lub caij nyoog ntawm lub sij hawm rov tsim dua, cov ntsiab lus ntawm cov roj rub rov qab tuaj yeem pom kev nce ntxiv, thiab qhov sib npaug ntawm Crosslink thiab Mooney viscosity tsis yeem. Lub zog tensile thiab elongation ntawm so poob nrog lub prolongation ntawm regeneration lub sij hawm. Thaum lub sij hawm rov tsim kua hlau mercury stearic acid yog 20 feeb, qhov Mooney viscosity tsawg dua, kev ua haujlwm zoo dua, lub zog tensile thiab elongation ntawm so yog tsawg, qhov hardness yog tsawg dua, thiab cov kev ua tau zoo dua qub.
