Umgangatho omtsha we-ASTM uya kusetyenziselwa ukuvavanya umgangatho we-silica, i-raw material eyenza isiseko samatayara "aluhlaza".Iinkampani zeTire kunye nabavelisi be-silica baya kuba ngabasebenzisi abaphambili bomgangatho omtsha (i-D8016, Indlela yoVavanyo ye-Silica, i-Precipitated, Hydrated - Sears Number).Ngokutsho kwelungu le-ASTM uJorge Lacayo-Pineda, itekhnoloji ye-silica iphucula ukusebenza kokumelana nokuqengqeleka kwamatayara ngaphandle kokuwohloka kokusebenza kwe-braking.Oku kukhokelela ekusebenzeni kakuhle kwamafutha, kunye nokunciphisa ukukhutshwa kwecarbon dioxide kwiimoto.Iinkampani zerabha, abasebenzisi abakhulu be-silica enqabileyo, banokuphucula ukucaciswa kwabo kwaye baqinisekise umgangatho wemveliso ngokuvavanya kumgangatho omtsha, utsho.Ikomitana ye-ASTM edale i-D8016 iceba ukwenza uvavanyo olujikelezayo lwe-robin entwasahlobo ezayo ukuvavanya ukuchaneka komgangatho omtsha.Iilebhu zeenkampani zerabha, abavelisi be-silica kunye namaziko emfundo bayakhuthazwa ukuba bajoyine.Abathathi-nxaxheba kuphononongo baya kunikwa iisampuli zokuhlalutya ngokwemigangatho emitsha.
I-silica enqabileyo
I-Bonding, i-anti adhesion, i-anti caking, i-coagulation, ukukhululwa okulawulwayo, umthwali, uncedo lokuhamba, ukuphucula umphumo wokushicilela, isenzo soomatshini, izongezo ezikhethekileyo ze-thermoplastic, ukuqinisa, ulawulo lwe-rheological kunye nomhlophe.I-Hydrophobic silica ephathwa ngokuguqulwa komphezulu inyibilika lula kwi-oyile.Xa isetyenziswa njenge-filler yokuqinisa kwirabha kunye neeplastiki, amandla omatshini kunye nokumelana nokukrazula kweemveliso zayo kuya kuphuculwa kakhulu.
I-silica ye-precipitated inoluhlu olubanzi lokusetyenziswa, kwaye iimveliso ezahlukeneyo zinosetyenziso olwahlukileyo.Njenge-arhente yokuqinisa irabha eyenziweyo, ukuqinisa ukusebenza kwayo kukwesibini kuphela kwikhabhoni emnyama, kwaye ingcono nangaphezu kwekhabhoni emnyama emva konyango oluphezulu nolufanelekileyo lomphezulu.Ilungele ngokukodwa ukuvelisa iimveliso zerabha ezimhlophe, umbala kunye nombala okhanyayo.Isetyenziswa njenge-thickener okanye i-thickener, i-agent yokudibanisa ye-oyile eyenziweyo kunye nepeyinti yokukhusela, i-agent e-dimming yepeyinti, i-agent ye-thixotropic ye-electronic component packaging materials, i-precipitant ye-phosphor ngexesha lokugquma kwesikrini se-fluorescent, isigcwalisi sepleyiti yoshicilelo lwerabha kunye ne-ejenti yokukhulula ukubunjwa. .Ukongeza kwi-resin kunokuphucula ubungqina bomswakama kunye neempawu zokugquma kwe-resin.Ukuzaliswa kweemveliso zeplastiki kunokunyusa ukuxhathisa i-skid kunye nokumelana neoli.
