Monga chosindikizira chachikhalidwe cha rabara, mphete yosindikiza mphira imayenera kukhala ndi kukhazikika bwino, mphamvu, kukana kuvala kwambiri, kulimba kwamphamvu komanso kutalika panthawi yopuma.Zizindikirozi zimakhala ndi zofunikira kwambiri ndipo zimatha kugwiritsidwa ntchito popanga zisindikizo za rabara zomwe zimagwira ntchito m'malo opanda mafuta komanso osawononga mpweya kuyambira -20 ° C mpaka 100 ° C.Pakati pawo, kukana kuvala kumakhudza mwachindunji moyo wautumiki wa mphete yosindikizira ndi zotsatira zosindikiza.Ndiye mungatani kuti muwonjezere kukana kwa mphete yosindikizira ya rabara pakupanga kwenikweni?
1. Moyenera onjezerani kuuma kwa mphira
Mwachidziwitso, kukulitsa kuuma kwa mphira kumatha kukulitsa kukana kwa rabala kuti zisawonongeke.Mphete yosindikiza mphira ndi malo olumikizirana amatha kulumikizidwa mofanana pansi pa kupsinjika, motero kumathandizira kukana kuvala.Nthawi zambiri, opanga mphete zambiri zomata mphira nthawi zambiri amawonjezera zomwe zili ndi sulfure kapena kuwonjezera mphamvu zina kuti muwongolere kuuma kwa mphira.
Tiyenera kukumbukira kuti kuuma kwa mphete yosindikizira mphira sikuyenera kukhala kwakukulu, mwinamwake kungakhudze kusungunuka ndi kutsekemera kwa mphete yosindikizira, ndipo pamapeto pake kumayambitsa kuchepa kwa kukana kuvala.
2. Kusintha mphira elasticity
Pofuna kuchepetsa mtengo wa zinthu za rabara, opanga mphira adzadzaza zodzaza zambiri, koma zodzaza mphira mochulukira zimachepetsa kusungunuka kwa mphira.Ndikofunikira kuwongolera mlingo moyenera, kuonjezera kusungunuka kwa mphira, kuchepetsa mamasukidwe akayendedwe ndi ma hysteresis a mphira, ndikuchepetsa kugundana kwamphamvu kuti muchepetse kukana kwa zisindikizo za rabara.
3. Sinthani kuchuluka kwa vulcanization
Malinga ndi mawonekedwe a mphira vulcanization ntchito, opanga mphira mankhwala moyenerera kusintha vulcanization dongosolo ndi vulcanization magawo a mphira zisindikizo kuonjezera mlingo wa vulcanization ndi kusintha kuvala kukana kwa mphira zisindikizo.
4. Kupititsa patsogolo mphamvu yamagetsi ya rabara
Pamene mphira umagwiritsidwa ntchito popanga mphete zosindikizira mphira, kugwiritsa ntchito mafinya amtundu wa rabara mu kapangidwe kake kumatha kukulitsa mphamvu ya intermolecular popititsa patsogolo kulimba kwamphamvu komanso kupsinjika kwa mphira, ndipo pamlingo wina kumapangitsa kuti mphira asavale.
5. Chepetsani kugundana kwapamwamba kwa mphete yosindikiza mphira
Kuonjezera zinthu monga molybdenum disulfide ndi graphite pang'ono mu ndondomeko ya mphete yosindikiza mphira kungachepetse kugundana kwa mphete yosindikiza ya rabara ndikuwongolera kukana kwa mphete yosindikiza.Opanga mphira akamagwiritsa ntchito mphira kupanga mphete zosindikizira mphira, amatha kugwiritsa ntchito mphira wobwezeretsedwanso kuti achepetse mtengo wazinthu zopangira mphira ndikupewa vuto la mphamvu zamakina ndi kuvala kukana kwa mphira komwe kumachitika chifukwa cha zodzaza kwambiri.Kukonzekera koyenera kwa mphira wosindikiza mphete, kusintha koyenera kwa magawo a ndondomeko ya vulcanization, ndi kusankha kwa zipangizo zoyenera komanso zabwino kwambiri za mphira sikungathe kuchepetsa mtengo wa zipangizo zosindikizira mphete, komanso kupititsa patsogolo kukana kwa mphete zosindikizira mphira.
