I-Silicon Dioxide (i-SiO₂) yeyona minerali yesibini efumaneka kakhulu kwi-inorganic crust yoMhlaba. Emva kokucocwa nokuhlanganiswa kwayo, isetyenziswa kakhulu kwizixhobo zokwakha, irabha, izixhobo ze-elektroniki, izinto zokuthambisa kunye nezinye iindawo, isebenza njengezinto eziphambili kwimveliso esisiseko neyeyona iphezulu.

1. Iinkqubo zemveliso (iindlela ezimbini)

(IsiNgesi)1）Indlela yendalo yokucoca izimbiwa

Isebenzisa i-quartzite, isanti ye-quartz, i-diatomite njengezinto eziluhlaza; isusa ukungcola kwe-Fe/Al ngokuyityumza, ukuyigaya kunye nokuyifaka emanzini. Ubumsulwa be-SiO₂ ≥98.5%, busebenza kakuhle, bufanelekile kwizixhobo zokwakha, kwiingubo nakwezinye izinto ezisetyenziswa ngokubanzi.

(2)Indlela yokwenziwa kweekhemikhali

Isebenzisa ii-silanes kunye nee-silicates njengezinto eziluhlaza; iveliswa yinkqubo yokufutha/yokuna kwemvula enolawulo lobushushu be-AI kunye ne-vacuum reaction. Ubumsulwa obufikelela kwi-99.9%+, ubungakanani besuntswana buyalawuleka ukusuka kwi-nano ukuya kwi-micron. Ilungele izixhobo ze-elektroniki, ii-semiconductors, izinto zokuthambisa eziphezulu; ithatha ngaphezulu kwe-60% yemarike ephezulu..

2. Iimpawu eziphambili

(IsiNgesi)1）Ukumelana nobushushu obuphezulu kunye nemozulu, iqondo lokunyibilika ~1800℃, ayimelani ne-UV, ayigugi okanye ayiboli emva kokusetyenziswa ixesha elide ngaphandle

(IsiNgesi)2）Inobuhlobo nokusingqongileyo kwaye ayinatyhefu, ayinasinyithi esinzima, ithobela i-EU REACH kunye ne-RoHS; ikhuselekile ekunxibelelaneni nokutya, iimveliso zabantwana, izinto zokuthambisa

(IsiNgesi)3）Ukuqinisa nokuqinisa, indawo ephezulu yomphezulu; kuphucula amandla okutsalwa nge-30%–50% kwirabha/iiplastiki

(IsiNgesi)4） Ukufunxwa kunye nokusasazeka kwe-embobo; isetyenziswa njenge-matting agent, i-desiccant, ithintela ukuqhekeka kunye nokungcola

3. Amashishini okusetyenziswa

(IsiNgesi)1）Izixhobo zokwakha

Yomeleza ukumelana nokuguguleka kwikhonkrithi/i-mortar; isebenza njenge-filler/matting agent kwi-coating/inhibition ukuze iqinise ukunamathela kunye nokumelana nemozulu.

(IsiNgesi)2）Irabha kunye neplastiki

Iqinisa amatayara, izitywino, iishelufu zekhebula; iphucula ukuqina kunye nokumelana nobushushu kwiipayipi, ii-cableholdings, kunye nokupakishwa kokutya. Ithengwe ngaphezulu kwama-40% amashishini aphambili erabha.

(IsiNgesi)3）Izinto zokuthambisa kunye nezinto ezivuselela imvakalelo

Udidi oluncinci olusetyenziselwa ukulawula ioyile kunye nokuseta izimonyo; udidi oluphezulu lokunyibilika kwizitena ezirhabaxa kunye nezinto zokuqhobosha kwisinyithi nakwimishini.

4. Imigangatho yoThengo

Iimfaneleko: thobela i-GB/T 30916-2014, isiqinisekiso se-ISO; i-REACH/FDA yokuthumela ngaphandle. Iinkcukacha: ubunyulu, ubungakanani bamasuntswana/indawo ethile yomphezulu, ukufuma ≤1%, intsalela ≤0.1%. Yenza uvavanyo lokuhambelana kweqela elincinci kuqala; beka phambili ababoneleli abaphicothiweyo ngokulungiselela kunye nenkxaso yobugcisa emva kokuthengisa.
