Izici zokusebenza ze-wollastonite

I-Wollastonite iyingxenye yensimbi yohlobo olulodwa lwe-silicate, enefomula ye-molecular Ca3 [Si3O9], futhi ngokuvamile isesimweni semicu, izinaliti, ama-flakes, noma imisebe.I-Wollastonite ngokuyinhloko imhlophe noma impunga emhlophe, inokucwebezela okuthile.I-Wollastonite ine-crystal morphology eyingqayizivele, ngakho-ke ine-insulation enhle, izakhiwo ze-dielectric, nokushisa okuphezulu kanye nokumelana nesimo sezulu.Lezi zakhiwo futhi ziyisisekelo sokunquma ukusetshenziswa kwemakethe kwe-wollastonite.

1. Izembatho
I-Wollastonite, enenkomba yayo ephezulu ye-refractive, amandla okumboza aqinile, nokumunca uwoyela ophansi, iyisigcwalisi esisebenzayo sezingubo zokwakha, okokulwa nokugqwala, okokuvikela amanzi nokungenamlilo.Ingathuthukisa ngokuphumelelayo amandla emishini yezingubo ezifana nokumelana nokugeza, ukumelana nesimo sezulu, ukumelana nokuqhekeka, nokumelana nokugoba, kanye nokumelana nokugqwala, ukumelana nesimo sezulu, nokumelana nokushisa.Ifaneleka ngokukhethekile ukukhiqiza upende omhlophe wekhwalithi ephezulu kanye nopende onemibala ecacile futhi esobala;Ngaphandle kokuthikameze ukumbozwa nokuwasha kwento enamathelayo, i-wollastonite ingashintsha i-20% -30% ye-titanium dioxide ohlelweni lwangaphakathi lodonga lwe-latex lokupenda, ithuthukise inani le-pH yesistimu, futhi yehlise izindleko zokukhiqiza zokumboza.

2. I-Ceramics
I-Wollastonite ingasetshenziswa kakhulu emikhiqizweni ye-ceramic efana namathayela acwebezelisiwe, izitsha zobumba zansuku zonke, izitsha zobumba ezihlanzekile, izitsha zobumba zobuciko, izitsha zobumba ezikhethekile zokuhlunga, i-ceramic glaze, insulating i-high-frequency ceramics ceramics, isikhunta se-ceramic engasindi, nezitsha zikagesi.Ingakwazi ukuthuthukisa ubumhlophe, ukumuncwa kwamanzi, ukunwetshwa kwe-hygroscopic, kanye nokumelana nokupholisa okusheshayo nokushisa kwemikhiqizo ye-ceramic, okwenza ukubukeka kwemikhiqizo kube bushelelezi futhi kukhanye, ngamandla andayo kanye nokumelana nokucindezela okuhle.Kafushane, imisebenzi ye-wollastonite ku-ceramics ihlanganisa: ukunciphisa izinga lokushisa lokudubula nokunciphisa umjikelezo wokudubula;Yehlisa ukuncipha kwe-sintering kanye nokukhubazeka kwemikhiqizo;Yehlisa ukunwetshwa kwe-hygroscopic yomzimba oluhlaza kanye nokwanda okushisayo phakathi nenqubo yokudubula;Thuthukisa amandla omshini womkhiqizo.

3. Irabha
I-Wollastonite ingangena esikhundleni senani elikhulu le-titanium dioxide, ubumba, ne-lithopone erabha enombala okhanyayo, idlala indima ethile yokuqinisa futhi ithuthukise ikhono lokumboza lombala omhlophe, idlala indima yokuba mhlophe.Ikakhulukazi ngemva kokuguqulwa kwezinto eziphilayo, i-surface ye-wollastonite ayinayo i-lipophilicity kuphela, kodwa futhi ngenxa yezibopho ezimbili ze-ejenti yokwelapha i-sodium oleate molecule, ingabamba iqhaza ekuvuthweni, ithuthukise ukuxhumanisa, futhi ithuthukise kakhulu umphumela wokuqinisa.

4. Ipulasitiki
Ukumelana okuphezulu, ukungaguquki kwe-dielectric ephansi, kanye nokumuncwa kwamafutha aphansi we-wollastonite kwenza izinzuzo zayo embonini yepulasitiki zibe sobala kunezinye izinto zamaminerali ezingezona ezensimbi.Ikakhulukazi ngemva kokuguqulwa, ukuhambisana kwe-wollastonite namapulasitiki kuthuthukiswa kakhulu, okungathuthukisa ngokuphumelelayo izakhiwo zepulasitiki nokuqinisekisa ukuzinza okushisayo, i-dielectric ephansi, ukumuncwa kwamafutha aphansi, namandla aphezulu omshini womkhiqizo.Kungase futhi kunciphise izindleko zomkhiqizo.I-Wollastonite isetshenziswa kakhulu ekukhiqizeni inayiloni, engathuthukisa amandla okugoba, amandla aqinile, inciphise ukumuncwa komswakama, futhi ithuthukise ukuzinza kwe-dimensional.

5. Ukwenza amaphepha
I-Wollastonite inenkomba ephezulu ye-refractive kanye nomhlophe okuphezulu, futhi njengesigcwalisi, ingakhuphula ukukhanya nokumhlophe kwephepha.I-Wollastonite isetshenziswa ekwenzeni iphepha, futhi inethiwekhi yefayibha yesitshalo se-wollastonite ewumphumela inesakhiwo esincane kakhulu, esithuthukisa ukusebenza kwephepha lokumuncwa kwe-inki.Ngesikhathi esifanayo, ngenxa yokushelela okuthuthukisiwe nokunciphisa ukukhanya, kwandisa ukuphrinta kwephepha.I-Wollastonite iphazamisa ukuboshwa kwemicu yezitshalo, iyenze ingazweli kumswakama, inciphise i-hygroscopicity nokuguqulwa kwayo, futhi ikhulise ukuqina kwephepha.Ngokwezidingo zephepha, inani lokugcwalisa le-wollastonite liyahlukahluka kusuka ku-5% kuya ku-35%.Ubumhlophe, ukuhlakazeka, kanye nokulingana kwempushana ye-wollastonite echotshoziwe ye-ultrafine kuthuthukiswe kakhulu, engangena esikhundleni se-titanium dioxide njengesigcwalisi sephepha.

6. I-Metallurgical protective slag
I-Wollastonite inezici zephuzu elincibilikayo eliphansi, i-viscosity encibilikayo ephansi yezinga eliphezulu lokushisa, kanye nokusebenza okuhle kokufakwa kwe-insulation, futhi isetshenziswa kabanzi ekuqhutshweni kwe-slag evikelayo eqhubekayo.Uma kuqhathaniswa ne-nonwollastonite protective slag, i-metallurgical protective slag esekelwe ku-wollastonite inezinzuzo ezilandelayo: ukusebenza okuzinzile nokuguquguquka okubanzi;Ayinawo amanzi ayikristalu futhi inokulahlekelwa okuphansi ekushiseni;Inamandla aqinile okukhangisa nokuncibilikisa okufakiwe;Inokuqina okuhle kwenqubo;Inemisebenzi emihle kakhulu ye-metallurgical;Inhlanzeko eyengeziwe, enempilo, futhi enobungani nemvelo;Ingathuthukisa ikhwalithi nokusebenza kahle kokukhiqizwa kokusakazwa okuqhubekayo.

7. Izinto zokungqubuzana
I-Wollastonite inezakhiwo ezifana nenaliti, izinga eliphansi lokunwetshwa, nokumelana nokushaqeka okuhle kakhulu okushisayo, okuyenza ibe indawo ekahle yefiber asbestos emfushane.Izinto zokungqubuzana ezilungiselelwe ngokufaka esikhundleni se-asbestos nge-high friction coefficient wollastonite zisetshenziswa kakhulu emikhakheni enjengama-brake pads, ama-valve plug, nama-clutches ezimoto.Ngemuva kokuhlolwa, konke ukusebenza kuhle, futhi ibanga lokubhuleka nempilo yesevisi ihlangabezana nezidingo ezifanele.Ngaphezu kwalokho, i-wollastonite ingenziwa futhi ibe sengathi uboya bamaminerali kanye nezindawo ezihlukahlukene ze-asbestos ezifana nokuvala umsindo, okunganciphisa kakhulu ukusetshenziswa kwe-asbestos futhi kunenzuzo ekuvikelweni kwemvelo nokuqinisekisa impilo yabantu.

8. I-electrode yokushisela
Ukusebenzisa i-wollastonite njengesithako sokuhlanganisa ama-electrode wokushisela kungaba usizo lokuncibilika kanye nesengezo sokwenza i-slag, cindezela ukukhishwa ngesikhathi sokushisela, unciphise ukuqhuma, uthuthukise uketshezi lwe-slag, wenze umphetho we-weld uhlanzeke futhi ube muhle, futhi uthuthukise amandla omshini.I-Wollastonite ingaphinde inikeze i-calcium oxide yokugeleza kwezinduku zokushisela, kuyilapho iletha i-silicon dioxide ukuze ithole i-alkaline slag ephezulu, enganciphisa ama-pores avuthayo nezinye iziphambeko emalungeni.Inani elingeziwe ngokuvamile liyi-10-20%.
