1. Lub shrinkage tus nqi ntawm cov roj hmab compound yog ib qho nyuaj heev thiab ntau yam teeb meem. Nws kuj yog ib qho teeb meem uas cov neeg tsim pwm yuav tsum tau ua tib zoo xav. Tam sim no, tsis muaj qhov tseeb, ua tiav, thiab cov qauv kev suav nrog. Nws tsuas yog tso siab rau kev kwv yees Empirical lossis tsub zuj zuj ntawm cov ntaub ntawv ntsuas tiag tiag tuaj yeem siv los ua kev siv. Vim hais tias txawm tias nws yog ib yam khoom siv roj hmab, tib lub pwm, thiab nyob rau hauv tib txoj kev mob, lub rooj sab laj peb-dimensional network technology, Yog hais tias qhov kub ntawm vulcanization yog tib yam, lub siab vulcanization yog tib yam, thiab tus nqi ntawm raw khoom. cov khoom ntxiv yog tib yam) vulcanization, tus nqi shrinkage tau tsis zoo ib yam
Yog li ntawd, qhov shrinkage tus nqi ntawm cov khoom ntsuas los ntawm qhov kev ntsuam xyuas kuj yog ib qho kwv yees tus nqi, ntxiv rau nws cuam tshuam los ntawm cov duab, hardness, molding txheej txheem thiab lwm yam ntawm cov khoom. Yog li ntawd, nws yog ib qho tsim nyog yuav tau qhia tus nqi kho ntawm qhov nruab nrab ntawm tus nqi ntsuas shrinkage, raws li hauv qab no:
1. Lub shrinkage tus nqi ntawm cov khoom siv roj hmab O-ring hloov raws li lub eeb-puab nkhaus nrog qhov nce ntawm hardness ntawm cov khoom vulcanized.
2. Lub shrinkage tus nqi ntawm cov khoom siv roj hmab O-ring nce nrog qhov nce ntawm cov khoom siv raw khoom txhaj rau hauv cov khoom vulcanized. Thaum qhov zoo ntawm cov khoom siv raw> cov khoom zoo yog 5% -10%, tus nqi shrinkage yog qhov ruaj khov.
3. Qhov zoo ntawm cov yas ntawm cov roj hmab, qhov me me ntawm qhov shrinkage; qhov siab dua qhov hardness ntawm cov roj hmab, qhov me me qhov shrinkage (tshwj tsis yog rau siab hardness)
4. Rau cov pwm nrog cov kab noj hniav ntxeem tau, qhov shrinkage tus nqi ntawm cov khoom vulcanized nyob rau hauv nruab nrab kab noj hniav yog ntau dua li ntawm cov khoom vulcanized nyob rau hauv lub ntug kab noj hniav.
5. Lub shrinkage tus nqi ntawm cov khoom nyias (section thickness tsawg dua 3 hli) yog 0.2% --- 0.6% loj dua li cov khoom tuab (section thickness saum 10mm)
6. Cov ntaub ntawv sandwich ntau dua, qhov tsawg dua qhov shrinkage tus nqi;
7. Kev nthuav dav thiab kev cog lus ntawm cov roj hmab O-ring hiav txwv cov khoom muaj ntau qhov sib txawv. Roj hmab O-ring hiav txwv khoom feem ntau siv thawj lossis theem nrab vulcanization. Thawj ua npuas ncauj vulcanization (re-qhov) pwm kab noj hniav yog raws li qhov loj ntawm cov khoom. Txo nws li ntawm 60%, thiab nthuav nws los ntawm 7% -10% raws li qhov loj ntawm cov khoom rau zaum ob raws li kev teeb tsa vulcanization.
8. Lub shrinkage tus nqi ntawm cov khoom siv roj hmab O-ring nce nrog kev nce ntawm cov roj hmab cov ntsiab lus ntawm cov khoom vulcanized
9. Lub shrinkage tus nqi ntawm cov khoom siv roj hmab O-ring nce nrog qhov nce ntawm vulcanization kub, thiab tus nqi shrinkage nce los ntawm 0.1% -0.2% rau txhua txhua 10 degrees ntawm kub nce.
10. Lub shrinkage tus nqi nyob rau hauv lub calendering kev taw qhia thiab cov kev taw qhia ntawm ntws nyob rau hauv lub pwm yog ntau tshaj lub shrinkage tus nqi nyob rau hauv txoj kev ntsug.
11. Qhov ntau qhov muab tub lim, qhov me me qhov shrinkage tus nqi; qhov ntau dua cov kua nplaum, qhov ntau dua qhov shrinkage tus nqi
12. Lub shrinkage tus nqi ntawm kev txhaj tshuaj-molded vulcanized khoom yog me ntsis me dua li ntawm molded-press vulcanized khoom.
13. Lub shrinkage tus nqi ntawm lub voj voog thiab square seem ntawm tib specification yog zoo sib xws
14. Roj hmab O-rings lined nrog hlau inlays muaj ib tug me me shrinkage tus nqi thiab shrinkage nyob rau hauv cov kev taw qhia ntawm hlau inlays.
