Kev ua haujlwm ntawm qhov ntsuas ntawm qhov chaw nres nkoj valve ntim hnab hauv daim ntawv thov
1. Cov cheeb tsam tshwj xeeb
Qhov loj ntawm kev txhawb zog ntawm cov xim dawb ntawm cov xim dub feem ntau yog nyob ntawm nws qhov tshwj xeeb ntawm thaj chaw feem ntau nce nrog thaj chaw tshwj xeeb, qhov ntsuas lub zog ntawm cov khoom siv roj hmab tau nce, tab sis qhov resilience yog txo, lub zog tearing yog txo, thiab nws tsis yog. hnav-resistant, nws yog ib qho nyuaj rau disperse thaum sib tov, lub tshav kub yog siab, lub viscosity ntawm cov khoom siv roj hmab yog loj, thiab cov cheeb tsam tshwj xeeb yog ib qho yooj yim mus hlawv, yog li ntawd, txawv formulations, sib txawv siv, qhov tshwj xeeb deg cheeb tsam yog tsis. tib yam. Kev cuam tshuam ntawm thaj chaw tshwj xeeb ntawm lub cev thiab lub zog ntawm cov roj hmab vulcanized tsis zoo ib yam.
2. Roj nqus tus nqi
Qhov loj ntawm cov roj nqus tus nqi qhia txog qib ntawm cov qauv, cov nqi nqus roj yog loj, cov qauv me me, lub zog elongation ntawm cov roj hmab vulcanized feem ntau loj, lub zog tensile thiab hardness yog loj, tshwj xeeb tshaj yog cov hnav tsis kam yog me me. , tab sis lub elongation yog tsawg.
3, 900 degree kub txo
Nws qhia tau hais tias thaum pawg hydroxyl deg ntau dhau lawm, nws yooj yim ua rau cov qauv ntawm cov khoom siv roj hmab sib xyaw, kom cov khoom ua nkig. Cov khoom ua haujlwm raug cuam tshuam, thiab cov roj hmab vulcanized yog ib qho yooj yim kom poob tawm, thiab cov pawg hydroxyl nto muaj cov nyhuv adsorption ntawm cov vulcanization accelerator, ncua lub sij hawm vulcanization.
4, 105 degree cua sov txo
Xav txog cov dej dawb hauv qhov sib txawv ntawm qhov sib txawv, tsawg dhau, qhov ntsuas ntawm cov qauv ntawm cov roj hmab sib xyaw ua haujlwm nyuaj, yog tias qhov txo qis cua sov yog xoom, cov xim dawb carbon dub tsis muaj txiaj ntsig, feem ntau tswj tau ntawm li 6% yog qhov tsim nyog dua.
5. PH tus nqi
Feem ntau nyob ib ncig ntawm 7, tus nqi PH nce (lub acidity txo), thiab vulcanization ceev ntawm cov khoom siv roj hmab yog nrawm. ,
6. Soluble ntsev
Qhov tsawg dua qhov zoo, tab sis qhov tsawg dua, tus nqi siab dua.
