SBR roj hmab sealing nplhaibyog siv dav hauv tsheb, khoom siv kho mob, thiab ntau yam khoom siv roj hmab, thiab cov khoom siv rau cov log tsheb SBR roj hmab sealing rings yog qhov loj tshaj plaws-hom hluavtaws roj hmab ntau yam, thiab nws kuj yog ib qho ntawm cov roj hmab ntxov tshaj plaws kom ua tiav cov khoom lag luam. Nws lub cev qauv kev ua tau zoo, kev ua haujlwm, thiab cov khoom ua tau zoo yog ze rau cov roj hmab ntuj.

Dab tsi yog styrene-butadiene roj hmab?
Styrene-butadiene roj hmab (SBR) yog suav hais tias yog cov roj hmab siv dav tshaj plaws uas ua rau niaj hnub no. Lub hom phiaj tseem ceeb ntawm cov roj hmab hluavtaws no yog tsim los ntawm cov copolymer ntawm butadiene thiab styrene, suav nrog 75% butadiene thiab 25% styrene. Cov monomers no tau txuas ua ib feem ntawm cov txheej txheem hu ua copolymerization los ua kom ntev, ntau chav tsev molecules uas rov randomly raws cov saw hlau polymer. Cov no yog tom qab sib txuas thaum lub sij hawm vulcanization txheej txheem.
Styrene-butadiene roj hmab muaj nyob rau hauv ntau yam ntawm ntug dej hardnesses ntawm 40 txog 95 IHRD thiab tuaj yeem ua haujlwm nyob rau hauv qhov kub thiab txias ntawm -25 degree thiab +90 degree rau static sealing.
Qhov zoo ntawm styrene-butadiene roj hmab
Styrene-butadiene roj hmab muaj ntau yam zoo. Nws yog feem ntau siv los hloov ncaj qha rau cov roj hmab ntuj, vim nws cov yam ntxwv zoo sib xws tab sis cov nqi pheej yig dua. Styrene-butadiene roj hmab muaj kev puas tsuaj zoo heev thiab kev ua kom tawg. Nws tseem muaj hnub nyoog zoo thiab xa cov compression zoo thiab dej tsis kam.
Nws yog qhov sib ntxiv ntawm cov organic compound styrene (ib qho derivative ntawm benzene) uas ua rau SBR lub zog muaj txiaj ntsig zoo, puas, hnav, thiab cov khoom sib txuas, tsis hais txog nws cov nqi pheej yig. Styrene-butadiene roj hmab feem ntau muaj cov khoom siv hluav taws xob zoo tshaj plaws thiab kev puas tsuaj ntau dua li cov roj hmab ntuj.
Disadvantages ntawm styrene-butadiene roj hmab
Ib qho tsis zoo ntawm styrene-butadiene roj hmab yog nws lub hnub ci tsis zoo thiab ozone tsis kam. Qhov no ua rau nws tsis tshua muaj txiaj ntsig hauv kev siv sab nraum zoov. Nws kuj tseem muaj qhov tsis zoo rau cov roj thiab cov nkev, ob qho tib si uas yuam SBR roj hmab kom o thiab tsis muaj zog thaum lub sijhawm.
Styrene-butadiene roj hmab lub tensile thiab abrasion lub zog tsuas yog ua tau los ntawm kev txhawb zog, xws li los ntawm cov muab tub lim zoo li carbon dub. SBR roj hmab tsis haum rau kev siv tshuaj, ozone, muaj zog acids, roj, rog, thiab feem ntau hydrocarbons.
daim ntawv thov
Styrene-butadiene roj hmab yog lub siab tshaj plaws ntim cov khoom siv hluavtaws roj hmab hauv kev tsim khoom niaj hnub no. Nws yog feem ntau siv nyob rau hauv kev tsim cov tsheb log tsheb thiab yog dav ua hauj lwm raws li ib tug puas-resistant, economical lwm yam rau tej yam ntuj tso roj hmab.
