Mububiko bwa reberi, ibizamini byinshi byo guhindagura bihoraho bikorwa kuruta ibizamini bihoraho. Nkuko tuzabiganiraho hepfo, ibintu byinshi bigize reberi bigira ingaruka kumiterere yabyo. Twabibutsa ko guhindagurika guhoraho no guhindagurika guhoraho ni ibintu bibiri bitandukanye. Kubwibyo, icyateza imbere compression ihoraho ntabwo byanze bikunze itezimbere ihindagurika rihoraho, naho ubundi. Byongeye kandi, kubikoresho byo gufunga reberi, guhinduranya ibintu bidahoraho ntabwo ari byiza guhanura igitutu cyangwa imikorere ya kashe. Mubisanzwe, uko igeragezwa ryoguhagarika umutima rigomba gukorwa, niko imikorere myiza yo gufunga ibicuruzwa iteganijwe.

Porotokole yubushakashatsi ikurikira ikoreshwa mugutezimbere imikorere ihoraho ya reberi. Icyitonderwa: Porotokole yubushakashatsi ntishobora gukoreshwa mubihe byose. Mubyongeyeho, impinduka zose zishobora kugabanya ihinduka rihoraho mugusenyuka cyangwa guhagarika umutima birashobora kugira ingaruka kubindi bintu kandi ntibizakemurwa mumyandiko.

1. Sisitemu yo kurunga

Tekereza ikoreshwa rya peroxide nkibikoresho byangiza, bishobora gukora CC ihuza imiyoboro bityo bigateza imbere guhoraho kwa reberi. Vulcanisation ya etylene propylene reberi hamwe na peroxide irashobora kugabanya ihindagurika rihoraho rya rubber. Ibyiza bya peroxide kurenza sulfure nuburyo bworoshye bwo gukoresha peroxide hamwe no guhindagurika gukabije guhoraho kwa reberi.

2. Igihe cya Vulcanisation hamwe nubushyuhe

Ubushyuhe bwo hejuru bwikirunga hamwe nigihe kinini cyibirunga birashobora kongera urwego rwibirunga bityo bikagabanya compression ya reberi.

3. Guhuza ubucucike

Kongera ubwuzuzanye bwa reberi birashobora kugabanya neza ihindagurika rihoraho rya reberi.

4. Sisitemu yo gutunga amashanyarazi

Kugirango tugabanye ihindagurika rihoraho ryimiterere ya EPDM no kunoza ubushyuhe, dushobora gutekereza kuri sisitemu ya '' deformasiyo yo hasi 'ya volcanisation (misa): sulfure 0.5PHR, ZDBC 3PHR, ZMDC 3PHR, DTDM 2PHR, TMTD3PHR.

Muri W ubwoko bwa neoprene, gukoresha umuvuduko wa diphenylthiourea birashobora gutuma reberi hamwe na compression nkeya ihindagurika, ariko ukirinda gukoresha CTP nka anti-coke, nubwo ishobora kongera igihe cyo gutwika, ariko ifite byinshi byangiza kuri compression ihoraho.

Kuri reberi ya NBR, muri sisitemu yatoranijwe y’ibirunga, ingano ya sulferi igomba kugabanuka, gerageza gukoresha sulfure kugirango utange umubiri nka TMTD cyangwa DTDM kugirango usimbuze igice cya sulfure, ibintu bitari bike bya sulferi bizamura imikorere yo guhindagura burundu imikorere ya reberi. Sisitemu yo kurunga hamwe na HVA-2 na hyposulfuramide irashobora gukora reberi hamwe na compression yo hasi ihindagurika.

5. Sisitemu ya peroxide

Guhitamo BBPIB peroxide bizaha reberi ihindagurika ryiza rihoraho muri compression. Muri sisitemu ya peroxide vulcanisation, ikoreshwa rya co-crosslinkers ryongera kutuzura muri sisitemu, ari nako biganisha ku bucucike bukabije, kubera ko guhuza radicals yubusa hamwe n’imigozi idahagije bibaho byoroshye kuruta gufata hydrogene muminyururu yuzuye. Imikoreshereze ya co-crosslinkers ihindura ubwoko bwurusobekerane bityo bigahindura compression ihoraho yimiterere yimiterere.

6. Nyuma y’ibirunga

Hariho ibirunga-by-ibicuruzwa mugihe cyibikorwa byo kuruka, kandi inzira ya nyuma yibirunga kumuvuduko wikirere ituma ibyo bicuruzwa bisohoka, bityo bigaha reberi yo kwikuramo hasi.

7. Fluoroelastomer FKM / Bisphenol AF Vulcanisation

Kuri fluoroelastomers, ikoreshwa rya bisphenol volcanizing agent aho gukoresha peroxide vulcanizing agent irashobora guha reberi ihinduka ridahoraho muri compression.

8. Ingaruka yuburemere bwa molekile

Muburyo bwa reberi, guhitamo reberi ifite uburemere buringaniye bwa molekile irashobora kugabanya neza ihindagurika rihoraho rya reberi.

Kuri reberi ya NBR, reberi ifite ubukonje bwinshi bwa Mooney igomba gukoreshwa, ishobora gukora reberi hamwe na compression ntoya ihindagurika.

9. Neoprene

W ubwoko bwa neoprene bufite compression yo hasi ihindagurika kuruta G ubwoko bwa neoprene.

10. EPDM

Kugirango ukore reberi hamwe na compression nkeya ihindagurika, gerageza wirinde gukoresha reberi ya EPDM hamwe na kristu nyinshi.

11. NBR

NBR, ni emulsion polymerized hamwe na calcium chloride ya calcium nka coagulant, mubisanzwe ifite compression nkeya.

Kuri reberi ya NBR, niba ushaka kwibanda kubikorwa byayo byo guhindagurika burundu, noneho gerageza uhitemo ubwoko bufite amashami maremare hamwe nuruhererekane runini cyangwa ubwoko butandukanye bwa acrylonitrile.

12. Rubber ya Ethylene-acrylate

Kuri AEM reberi, imiti ya peroxide irashobora gutanga compression yo hasi kuruta diamine vulcanizing agent.

13. Resin-ishingiye kuri homogenizers

Irinde gukoresha resin ishingiye kuri homogenizers munganda ya reberi, kuko ibi byongera compression yashizwemo.

14. Abuzuza

Kugabanya ibyuzuye, imiterere nubuso bwihariye bwuzuza (kongera ingano yubunini) bizagabanya guhagarika compression. Mugihe kimwe, kongera ibikorwa byubuso bwuzuye birashobora kandi kunoza compression yashizeho irwanya uruganda.

15. Silika

Silica yo hasi yuzuza ibice bizagabanya compression yashizweho. Kugirango ugire compression yo hasi, birakenewe kwirinda kuzuza silika nyinshi. Niba ubwuzure burenze ibice 25 (kubwinshi), compression ihoraho ihindagurika yikigo iba nini.

16. Umukozi wo guhuza Silane

Urebye ikoreshwa rya silane ihuza ibintu byinshi byuzuye bya silika yaguye, compression ihoraho ihindagurika irashobora kugabanuka. Ibikoresho byo guhuza Silane birashobora kugabanya ihindagurika rihoraho rya silika yuzuye reberi, kandi ikanagabanya ihindagurika rihoraho ryimiterere yubwoko bwa silikatike nkibumba, ifu ya talcum nibindi byuma byuzuye.

17. Amashanyarazi

Kugabanya umubare wuzuye wa plasitiki muri reberi mubisanzwe bizagabanya ihindagurika rihoraho rya reberi.
