Daim Ntawv Thov Ntau Yam

HP-669 siv tau zoo hauv kev lag luam roj hmab ua tus neeg sawv cev sib txuas ob txoj haujlwm organic poly sulfur silane.
HP-669 siv tau rau hauv lub kaw lus roj hmab vulcanized nrog cov khoom sau xws li silica, fiberglass, hmoov talc, hmoov mica thiab av nplaum ua tus neeg sawv cev txhawb nqa. Nws tuaj yeem txhim kho cov khoom txhawb nqa ntawm cov khoom sau thiab cov khoom tiv thaiv roj hmab abrasive.
Nws yog qhov tsim nyog siv los ua cov roj hmab additive-vulcanizing agent thiab activator hauv polymers xws li NR, IR, SBR, BR, NBR thiab EPDM.
Hauv cov txheej txheem ntawm vulcanization, qhov sib txuas ntawm poly-sulfur alkyl yog tib yam li deoxidizing tus nqi ntawm sulfur, yog li nws ua rau tiv thaiv deoxidization ntawm vulcanization, thiab tom qab ntawd txhim kho cov khoom siv dynamic bending xws li cua sov tsim thiab tawg nthuav dav. Plaub lub sulfur atoms tuaj yeem ua raws li activator rau vulcanization.
Hauv cov xwm txheej dynamic thiab static, nws yog siv los tsim cov khoom siv roj hmab no: log tsheb, hose, roj hmab dov, siv txoj siv sia, cable, khau thiab cov khoom siv kho tshuab. Nws tuaj yeem txhim kho kev tiv thaiv abrasive, txiav tsis kam thiab siab tsis kam, txo hysteresis poob thiab hygroscopicity, txhim kho cov khoom siv kho tshuab thiab nplaum, thiab nce thermal laus kev ua tau zoo, modulus thiab flex lub neej.
Ntxiv cov sulfur-silane coupling agent rau hauv kev lag luam roj hmab log tsheb, nws tsis yog tsuas yog txo qhov kev pheej hmoo ntawm kev tawg vim qhov kub siab dhau thaum khiav ntawm txoj kev ceev ceev lossis ntev, tab sis kuj txo qhov kev tiv thaiv ntawm lub log tsheb, tom qab ntawd txo qhov kev siv roj av, cov pa roj carbon ntau ntxiv kom ua raws li kev tiv thaiv ib puag ncig ntawm kev txo cov pa roj carbon.
