Qhov tseem ceeb ntawm kev siv coupling tus neeg sawv cev hauvsilicareinforced tsawg hardness butyl roj hmab
Butyl roj hmab muaj huab cua nruj zoo, dej nruj, tiv thaiv tshav kub, kev poob siab thiab tshuaj lom neeg ruaj khov. Nws tuaj yeem siv rau hauv kev tsim thiab kev npaj ntawm ntau lub log tsheb, sealing washers, anti-corrosion linings, tshav kub-resistant conveyor siv, thiab cov ntaub ntawv waterproof. Nws muaj cov txiaj ntsig zoo siv thiab cov khoom siv ntev. Hauv cov khoom siv roj hmab uas tsis muaj zog butyl, cov tuam txhab roj hmab feem ntau siv silica hloov los ntawm kev sib txuas tus neeg sawv cev rau kev txhawb nqa, es tsis txhob siv silica ncaj qha. Vim li cas? Dab tsi yuav tsum tau them sai sai rau thaum siv silica / coupling tus neeg sawv cev rau qhov tsis tshua muaj zog butyl roj hmab?
1. Yog vim li cas rau kev siv coupling tus neeg sawv cev los hloov cov pa roj carbon monoxide dawb rau kev txhawb zog tsawg hardness butyl roj hmab
Raws li peb txhua tus paub, lub luag haujlwm ntawm butyl roj hmab thiab tus neeg sawv cev txhawb zog tsis muaj zog. blindly nce tus nqi ntawm tus neeg sawv cev reinforcing yuav tsis tsuas yog ua rau pov tseg ntawm raw cov ntaub ntawv, tab sis kuj yuav ua rau muaj teeb meem rau butyl roj hmab cov khoom ua yog hais tias tus reinforcing tus neeg saib xyuas tsis tau uniformly dispersed nyob rau hauv cov khoom siv roj hmab. Yog li ntawd, thaum siv tus neeg sawv cev txhawb nqa hauv cov khoom siv roj hmab butyl, tus neeg sawv cev txhawb nqa feem ntau yog cov cua sov kho ua ntej lossis hloov kho nrog tus nqi tsim nyog ntawm cov khoom ntxiv.
Silica yog cov khoom lag luam nrog cov txiaj ntsig zoo tshaj plaws ntawm cov khoom siv roj hmab roj hmab, tab sis kev siv silica ib leeg tsis tuaj yeem ua tiav cov txiaj ntsig zoo tshaj plaws. Yog li ntawd, cov khoom lag luam roj hmab feem ntau siv silane coupling tus neeg sawv cev 2YLYY31 los hloov silica. Thaum cov roj hmab butyl tau siv los npaj cov roj hmab uas tsis tshua muaj zog butyl roj hmab, tus neeg sawv cev sib txuas hauv cov pa roj carbon dub tuaj yeem txhim kho cov nyhuv ntawm cov pa roj carbon dub hauv butyl roj hmab, thiab txhim kho lub zog tensile, elasticity, hnav tsis kam thiab lwm yam ntsuas ntawm butyl roj hmab.
Hauv kev tsim khoom tiag tiag, cov khoom siv roj hmab butyl nrog silica / coupling tus neeg sawv cev muaj kev sib xyaw ntau dua kev nyab xeeb thiab kev kho ceev ceev.
2. Ntxiv kev txawj ntawm silica/coupling tus neeg sawv cev nyob rau hauv tsawg hardness butyl roj hmab
(1) Cov teeb meem tshwm sim: Thaum cov xim dawb carbon dub / silane coupling tus neeg sawv cev yog siv los npaj cov khoom siv roj hmab uas tsis tshua muaj zog, yog tias cov khoom siv roj hmab dub kuj tseem siv rau hauv cov mis, vim tias cov khoom siv sib txawv ntawm cov khoom sib txawv muaj qhov sib txawv ntawm cov roj hmab butyl, cov khoom siv roj hmab. manufacturers yuav tsum paub lub sij hawm ntxiv peb hom raw khoom. Ntxiv cov pa roj carbon dub thiab tom qab ntawd ntxiv cov pa roj carbon dub / tus neeg sawv cev sib txuas lossis ntxiv cov pa roj carbon dub / tus neeg sawv cev sib txuas ceev heev yuav ua rau cov pa roj carbon dub Lub zog txhawb zog ntawm silica hauv butyl compound txo qis heev.
(2) Kev daws teeb meem, Tom qab ntawd cov pa roj carbon dub tau ntxiv me me rau ntau zaus kom ntseeg tau tias cov roj hmab butyl muaj qhov ua tau zoo thiab cov dej ntws zoo, thiab ua kom tsis txhob muaj teeb meem xws li npuas rau ntawm cov khoom uas tsis tshua muaj zog butyl roj hmab thiab cov npoo tawg ntawm cov kab sib cais. .
Thaum twgdawb carbon dubyog siv los txhawb cov khoom siv roj hmab uas tsis tshua muaj zog uas tsim los ntawm cov roj hmab butyl, cov khoom lag luam roj hmab feem ntau siv silane coupling tus neeg sawv cev los hloov cov pa roj carbon dub. Cov ntau yam yog coupling agent Si-69. Kev laus ua haujlwm ntawm kev hloov kho butyl roj hmab cov khoom yuav raug kho kom zoo nrog qhov nce ntawm cov xim dawb carbon dub. Nws yuav tsum raug sau tseg tias feem ntau, thaum silane coupling tus neeg sawv cev Si-69 hnov mob nrog silica, tsuas yog li 50 feem pua ntawm cov nyiaj ntxiv feem ntau koom nrog cov tshuaj tiv thaiv, thiab nws yuav tsum tau nres li 24 teev thaum siv.
