I-Yellowing yeemveliso ze-silicone: Icala eliqhelekileyo le-silicone yi-silicone ifowuni yeselula.I-yellowing phenomenon yinto ephambili yeemveliso ze-silicone eziqhelekileyo.Ngokuqhelekileyo, imveliso iya kuba tyheli emva kokusetyenziswa ixesha elide emva kotshintsho lwendalo, kodwa i-anti-yellowing yongezwa kuyo.I-ejenti inokufezekisa i-phenomenon ye-non-yellowing, okanye ukusetyenziswa kwezinto eziluhlaza ze-silica gel kunye ne-fumed silica, ukukhanya okuphezulu, ukuqina okuphezulu, kunye nekhwalithi ephezulu ye-silica gel izinto aziyi kujika ziphuzi.Ukuba imveliso oyithengayo i-silicone eqhelekileyo kwaye akukho arhente ye-anti-yellowing eyongeziweyo, iya kubangela ukuba imveliso ibe tyheli.Ke ngoko, xa uthenga imikhono ye-silicone, musa ukunyoluka ngexabiso eliphantsi.Ixabiso lemveliso lixhomekeke kumgangatho wemveliso.
Ukongeza, isenokuba yinkqubo yemveliso.Ukuba ubushushu bomngundo wemveliso buphezulu kakhulu okanye inkqubo ye-vulcanization ithatha ixesha elide ngexesha lokubumba, kunokubangela ukuba umbala wemveliso ye-silicone ujike ube tyheli, nto leyo efuna ukuba silawule ngokungqongqo iziphumo zemveliso.Ukuba iqondo lokushisa lokubumba kunye nexesha lokuphilisa lemveliso alilawulwa kakuhle, iimeko ezininzi ziya kwenzeka.
Nangona kukho izizathu ezininzi ze-yellowing yeemveliso ze-silicone, indlela esinokuziphepha ngayo kukuba kufuneka sikhethe abavelisi abagqwesileyo kwiimveliso ze-silicone yesiko, kwaye asiyi kusebenzisa izinto eziphantsi kunye neenkqubo zokuvelisa ezivuthiweyo.Ayiyi kubangela umgangatho ophantsi wemveliso yokugqibela.
Izixhobo ze-silicone ezisetyenziswa yi-Weishun Silicone Products Technology Co., Ltd. zonke ziyi-silicone yezinga eliphezulu lokutya, eliye ladlula uvavanyo lwe-FDA kunye ne-LFGB.Ngelo xesha, sineminyaka engaphezu kwe-15 yamava okuvelisa kwaye siqhelene kakhulu neempawu kunye neentsilelo zeemveliso ze-silicone.Siya kucebisa iinkqubo ezifanelekileyo kubathengi ngokusetyenziswa kwemveliso kunye neempawu, ukwenzela ukuba benze iimveliso ezifanelekileyo kakhulu.
