Tonse timakumana ndi zinthu zina zosintha pa ntchito yathu ya tsiku ndi tsiku, monga zinthu za latex zimasanduka zoyera zikasungidwa kutentha kwa firiji, ndipo waya wa waya wa silicone umasanduka wachikasu pakutentha kwambiri.
Monga ngatiwaya wotentha wa siliconezomwe timagwiritsa ntchito nthawi zambiri m'miyoyo yathu, zidasanduka zachikasu zitayikidwa pa kutentha kwakukulu kwa 200 ℃ kwa maola 4.Chikuchitika ndi chiani?
Vutoli litha kuthetsedwa pogwiritsa ntchito silikoni yapamwamba yotsutsa chikasu vulcanizer C-15.Nthawi zambiri, zinthu zamagulu a zakudya zimakhala ndi izi.
Pofuna kupewa chikasu chifukwa chowonjezera sulfure yachiwiri, anti-yellowing catalyst + anti-yellowing agent iyenera kugwiritsidwa ntchito.Onse awiri ndi ofunika kwambiri.
Komabe, zinthu ziwirizi zimapangitsa kuti zikhale zomata pang'ono panthawi yopanga mafuta, zomwe ndizofunikira kuziganizira.
Onjezani 2-3 zikwi zamafuta a silicone okhala ndi haidrojeni malinga ndi kuchuluka kwa silikoni.Mafuta a silikoni okhala ndi haidrojeni wambiri amatha kuthetsa vuto lachikasu, koma mankhwalawo amatha kukhala olimba komanso omata.
Mutha kupopera mafuta osanjikiza a silikoni pa nkhungu kuti muthane ndi vutoli.Kuphatikiza apo, mlatho wokha wa platinamu ungagwiritsidwe ntchito.
Opanga amasanthula kuti kugwiritsa ntchito anti-yellowing agents ndi anti-yellowing vulcanizers ndi lingaliro labwino, koma muyeneranso kusamala ngati waya wotenthetsera wa silicone womwe mukugwiritsa ntchito ndi wabwino.
Simungathe kuwonjezera chotulutsa chochuluka cha nkhungu, zinc stearate, kotero muyenera kulankhulana ndi wogulitsa kuti mudziwe ngati muli kale mafuta a hydrogen silikoni mmenemo kuti apereke anti-yellowing effect.
Ufa ndi wofunika kwambiri.Ngati chitsulo chili chochuluka, chimasanduka chachikasu.Ngati simukudziwa kuchuluka kwake, mutha kuyerekeza kaye vulcanizer wamba (popanda anti-yellow agent) ndi vulcanizer yokhala ndi anti-yellowing agent.
Samalani kuti musawonjezere zotulutsa zinc stearate mold.Ngati sichikugwirabe ntchito, ndibwino kuti mugwiritse ntchito mphira ina kapena mugwiritse ntchito platinamu vulcanizer.
Ngati m'chilengedwe muli chonyamulira cha sulfure kapena sulufule (monga zinthu zophikidwa ndi sulfure zomwe zaphikidwanso mu uvuni kachiwiri), zipangitsanso kuti waya wotenthetsera wa silicone ukhale wachikasu.
Chonde khalani omasuka kulumikizana nafe kuti mumve zambiri za waya wa waya wa silicone.
