Nyob rau hauv cov roj hmab compounding, ntau compression kev ntsuam xyuas kev sib raug zoo sib raug zoo dua li tensile kev sim deformation. Raws li yuav tau sib tham hauv qab no, muaj ntau yam ntawm cov roj hmab cov roj hmab cuam tshuam nws cov khoom deformation. Nws yuav tsum tau sau tseg ntawm no tias compressive excormation thiab tensile kev sib raug zoo yog ob qho sib txawv. Yog li ntawd, dab tsi txhim kho compression excormation tsis tas yuav tsum tau txhim kho tensile kev tawm tsam tsis tu ncua, thiab hloov ua lwm yam. Ib qho ntxiv, rau cov khoom siv roj hmab, compressive excormation tsis yog qhov ua tau zoo ntawm kev ua kom zoo los yog kev ua tau zoo. Feem ntau, cov nyuab zog rau compressive kev ntxhov siab kev sim yog yuav tsum tau ua, qhov zoo dua kev sib khi ua tau ntawm cov khoom yog kwv yees.
Cov kev sim ua hauv qab no yog siv los txhim kho kev deormation kev ua tau zoo tas mus li ntawm cov roj hmab. Lus Cim: Cov kev sim no yuav siv tsis tau rau txhua kis. Tsis tas li ntawd, ib qho sib txawv uas tuaj yeem txo qhov kev tawm tsam kev ruaj khov hauv compression los yog nro tuaj yeem cuam tshuam lwm cov khoom thiab yuav tsis raug hais hauv cov ntawv nyeem.
1. Vulcanization System
Xav txog kev siv cov tshuaj parsoxides uas yog vulcanizing cov neeg sawv cev, uas tuaj yeem ua CC Hla kev sib tsoo thiab txhim kho kev sib txuas ntawm cov roj hmab. Vulcanization ntawm ethylene roj hmab nrog peroxide tuaj yeem txo qhov compression kev sib raug zoo ntawm cov roj hmab. Qhov zoo ntawm peroxide tshaj li tus sulfur yog qhov yooj yim ntawm kev tuav peroxide thiab qhov qis compressive excormation ntawm cov roj hmab.
2. Vulcanization Sijhawm thiab Kub
Ntau dua vulcanization kub thiab ntev siv lub sij hawm volcanization ntev tuaj yeem nce qib ntawm vulcanization thiab yog li txo cov comp ntawm cov roj hmab.
3. Hla kev sib txuas ntom ntom ntom ntom ntom
Nce cov ntoo khaub lig ntom ntom ntom ntom roj hmab yuav ua tau zoo txo cov compression kev sib raug zoo ntawm cov roj hmab.
4. Sulphur vulcanization system
Txhawm rau kom txo tau cov compressive deformation ntawm epdm compound thiab txhim kho qhov no yog 'tsawg deform ' tsis tshua muaj zog '
Hauv W Hom Neoprene, kev siv cov roj av dipherylisea tuaj yeem ua rau cov roj hmab tsis muaj zog, tab sis nws muaj kev puas tsuaj ntau ntxiv rau kev sib raug zoo sib txawv.
Txog cov roj hmab mos, hauv cov qauv vulcanization, tus nqi ntawm cov leej faj yuav tsum tau muab cov leej txiv los sis tsis muaj cov khoom noj los ntawm cov roj hmab sib txuas lus ntawm cov roj hmab. Lub cev tsis huv uas muaj HVA-2 thiab hyposulfurfuramide tuaj yeem ua rau cov roj hmab nrog kev sib txawv ntawm kev sib txawv.
5. Peroxide Vulcanization System
Qhov kev xaiv ntawm Bbpib peroxide yuav muab cov roj hmab zoo dua deformation hauv compression. Nyob rau hauv peroxide vulcanization tshuab, kev siv cov co-crosslinkers nce rau ib tug loj radicals, uas nyob rau hauv lem uas tsis muaj kev sib tw tau tshwm sim ntau dua li kev noj hydrogen los ntawm cov saw hlau dawb. Kev siv ntawm co-crosslinkers hloov cov hom ntawm crosslinking network thiab yog li txhim kho lub zog compression kev sib raug zoo ntawm cov nplaum.
6. Ncua-Vulcanization
Muaj volcanization los ntawm cov khoom lag luam thaum lub sijhawm ua kom tiav cov txheej txheem ntawm cov khoom siv vulcanizer cia cov khoom lag luam no, yog li muab cov roj hmab tso tawm.
7. Fluoroelastomer FKM / BISHENOL AF VULCANANS
Rau cov tshuaj fluoroelastomers, kev siv ntawm Bisphenol vulcanizing tus neeg sawv cev ntawm tus neeg sawv cev ua kom cov roj hmab qis zuj zus los ntawm compression.
8. Cov nyhuv ntawm molecular hnyav
Hauv cov roj hmab yas, kev xaiv roj hmab nrog qhov nruab nrab loj molecular hnyav yuav txo tau zoo txo ntawm cov roj hmab.
Rau cov roj hmab mos, cov roj hmab nrog cov roj hmab siab yuav tsum tau siv, uas tuaj yeem ua rau cov roj hmab nrog cov txheej txheem me me.
9. Neoprene
W hom neoprene muaj qis dua kev sib txuas lus tsis sib xws g hom neoprene.
10. EPDM
Txhawm rau cov roj hmab nrog cov roj av qis dua excormation, sim kom tsis txhob siv EPDM roj hmab nrog siab crystallinity.
11. NBR
NBR, uas yog emulsion polymerized nrog calcium chloride li coagulant, feem ntau muaj qhov tsis muaj txiaj ntsig.
For NBR rubber, if you want to focus on its compression permanent deformation performance, then try to choose varieties with high branching and high chain entanglement or varieties with low acrylonitrile content.
12. Ethylene-acrylate roj hmab
Rau AEM Rubbers, Peroxide Vulcanizing cov neeg sawv cev tuaj yeem muab qhov qis dua kev teeb tsa dua li cov neeg sawv cev sib dhos.
13. Resin-raws homogenizers
Zam kev siv cov resin-raws homogenizers nyob rau hauv cov roj hmab tebchaw, raws li qhov no nce compression teeb ntawm lub compound.
14. Loorers
Txo cov qauv txhaws, cov qauv thiab thaj chaw tshwj xeeb ntawm cov muab tub lim (nce qhov loj me me) feem ntau yuav txo cov teeb pom kev. Nyob rau tib lub sijhawm, nce kev ua si ntawm cov muab cov tub lim saum npoo av tseem tuaj yeem txhim kho cov kev teeb tsa kev siv hluav taws xob ntawm cov compound.
15. Silica
Qis silica muab tub lim hauv qhov sib txuas yuav txo cov txheej txheem kev teeb tsa. Txhawm rau kom muaj cov teeb pom kev yooj yim, nws yog qhov tsim nyog kom tsis txhob muaj qhov chaw sau siab ntawm silica. Yog hais tias sau kom muaj nuj nqis yog siab dua 25 ntu (los ntawm huab hwm coj), lub compressive sib txawv deformation ntawm cov compound ua loj.
16. Txhaws Coupling Tus Neeg Sawv Cev
Xav txog kev siv cov neeg ua haujlwm sib txuas ntawm cov neeg ua haujlwm sib txuas lus hauv qhov siab uas tau ua tiav ntawm Silica, lub compression nrog cov nplaum uas muaj peev xwm txo tau. Cov roj hmab sib txuas lus tuaj yeem txo cov roj teeb sib txawv ntawm silica puv roj hmab, thiab tseem muaj hmoov av, talcum hmoov thiab lwm cov roj hmab tau ua tiav.
17. Yas
Txo qhov txhaws ntawm cov yas roj hmab hauv cov roj hmab feem ntau yuav txo cov compression excormation kev sib raug zoo ntawm cov roj hmab.
