Yuav ua li cas txhawm rau txhim kho cov kub tsis kam ntawm roj hmab?

Kuj muaj huab cua kub laus lossis kev laus kub yog qhov tseem ceeb ntxiv, tshwj xeeb hauv cov chaw roj hmab feem ntau siv nrog cov huab cua zoo. Automotive cov tuam ntxhab tau hnov ​​ntau dua los cog lus siv sijhawm ntev rau lawv cov roj hmab ntu. Anaerobic kub ntxhov siab cov khoom thiab cua sov thiab cua laus sib txawv yog qhov sib txawv. Cov roj hmab muaj cov kub ua kom zoo dua, tab sis kuj tseem yuav tiv taus oxygen nres.

NCO TSEG: Cov kev ntsuam xyuas cov kev ntsuam xyuas dav dav no yuav siv tsis tau rau txhua rooj plaub tshwj xeeb. Ib qho ntawm cov hloov pauv uas tuaj yeem txhim kho cov cua-aging tsis kam lossis tshav kub-laus yuav muaj kev cuam tshuam rau lwm lub zog, los ua kom zoo dua qub.

1. Perfluoroelomer

Yog tias cov khoom siv roj hmab yog qhov yuav tsum muaj kom muaj lub kub ua hluav taws kub zoo, koj yuav tsum xaiv cov roj hmab perfluorinated roj hmab. Nws tau tshaj tawm tias kev siv kub ntawm perfluoroelomer yog txog 316 ℃.

2, roj hmab fluorine

Fluorine Roj Hmab FKM muaj cov kub ua kom zoo, thiab nws tuaj yeem siv nyob rau ntawm qhov kub txog rau 260 ℃. Txhawm rau ntxiv dag zog rau cov pa roj fluorine, calcium oxide, cov tshuaj tsw qab, thiab siv cov fluoroelastic, thiab cov roj ntsha Los ntawm kev xaiv Bisphenol AF li lub cev vulcanization, cov kev laus tshav kub tiv thaiv cov roj hmab yuav zoo dua. Siv nyob rau hauv kev siv roj hnyav cav huab ib puag ncig, cov kev ua cua sov ua kom tsis muaj tshuaj lom thiab ua kom zoo dua qub thiab cov tsiaj fluoroelastomer. Qhov no yog vim kev hloov ntawm Hexafluoropropene los ntawm kev ua kom muaj mob rau cov txheej txheem polymerization.

3, hnbr

Lub siab dua qib ntawm hydrogenation, qhov zoo dua cov cua sov tsis kam ntawm HNBR, vim tias muaj yuav luag tsis muaj kev lag luam tseem ceeb ntawm lub ntsiab uas tsis ruaj khov. Ib co HNBRS tseem tuaj yeem yog cov neeg yaj phom nrog leej faj vim tias lawv tseem muaj qee cov nyiaj txhov ob npaug. Txawm li cas los xij, yog tias vulcanized nrog peroxide nrog peroxide, cov cua sov tsis kam ntawm cov compound yuav txhim kho. Rau cov roj hmab Hnbr, Topm tuaj yeem muab cov kub kub ua tau zoo dua li DOP vim yog qhov tsis tshua muaj neeg muaj zog thiab hnyav molecty ntawm cov cab hlau no.

4. Neoprene

W-hom neoprene muaj cov kev tiv thaiv tshav kub zoo dua li G-hom neoprene. Diphenylamine Octanoate yog ib qho antioxidant zoo dua rau neoprene, uas tuaj yeem txhim kho cov cua sov ua kom tsis kam.

5, epdm

EPDM tseem muaj kub kub tiv thaiv thaum 125 ℃ tom qab haum haum. Kev siv cov tshuaj Peroxide Vulcanized EPDM, tuaj yeem ua rau cov roj hmab muaj cov cua sov zoo dua.

6, qis viscosity vapor theem qauv EPDM

Cov khoom siv hluav taws xob siab thiab ultra-qis viscosity, tuaj yeem tsim cov khoom siv hluav taws xob, yog li cov khoom siv ua kom zoo, yog li cov roj hmab zoo dua ntawm cov roj hmab tau txhim kho.

7, zam kev siv cov resin high styrene

Zam kev ntxiv cov khoom dua tshiab rau cov roj hmab siv hauv qhov kub kub.

8, talcum hmoov

Nyob rau hauv EPDM Hose roj hmab, hloov 40% ntawm cov pa roj hmab dub nrog Talcum hmoov, uas tuaj yeem txhim kho cov roj hmab kev kub ntxhov tsis kam ntawm cov roj hmab. Qee qib ntawm Talcum hmoov muaj ntau dua zoo dua li kho cov av nplaum lossis tsis kho av nplaum hauv qhov no.

9, siab viscosity yas

Ntawm cov tshuab yas, cov viscosity siab viscosity tuaj yeem muab cov cua sov uas zoo dua li cov viscosity tsawg. Vim tias lub siab viscosity castikas feem ntau muaj cov molecular hnyav, tsis yooj yim rau kev loj hlob, yog li zoo ruaj khov thiab muaj cua sov tsis kam.

10, cov neeg siv roj rau neoprene

Txhawm rau ua kom neoprene muaj cov roj roj zoo dua, cov roj av canola vim tias nws muaj cov roj hmab muaj tsawg, uas tuaj yeem ua rau cov roj hmab muaj kev laus tsis kam.

11, Siv tau tau Evi-semi muaj txiaj ntsig zoo li teev ntawm Sev Vulcanization System

Nyob rau hauv cov txheej txheem volcanization zoo, qhov sib piv ntawm cov roj av uas muaj kev sib raug zoo, yog tias nws muaj kev ruaj khov ntawm cov roj hmab kom siab dua, Recio ntawm ib leeg Sulphur daim ntawv cog lus thiab ob npaug rau cov kab lus sab nrauv yog siab dua li ntawm cov roj hmab muaj zog ntawm cov roj hmab tau txhim kho thiab cov kev laus tshav kub kuj yog txhim kho.

12, Zinc Oxide

Vulcanization / Sub-Sulfuramide System of Cov roj hmab, tau muab cov roj hmab ntau dua zoo dua li cov khoom kub thiab zoo dua rau tom qab-Sulphur.

13, Peroxide vulcanized EPDM roj hmab

Nyob rau hauv peroxide vulcanized epdm compet, ZMTI yog xaiv los ua antioxidant, uas tuaj yeem muab cov compound ntau modulus thiab kev laus tiv thaiv ntau dua.
