Izici zokusebenza kwe-wollastonite

I-Wollastonite ingeyohlobo olulodwa lwe-ore ye-silicate, enefomula yama-molecule i-Ca3 [Si3O9], futhi ngokuvamile isesimweni semicu, izinaliti, ama-flakes, noma imisebe. I-Wollastonite imhlophe noma imhlophe ngokugqamile, inokukhanya okuthile. I-Wollastonite inokwakheka kwekristalu okuhlukile, ngakho-ke inokushisa okuhle, izakhiwo ze-dielectric, kanye nokumelana nokushisa okuphezulu nesimo sezulu. Lezi zakhiwo nazo ziyisisekelo sokunquma ukusetshenziswa kwemakethe kwe-wollastonite.

1. Ukwemboza
I-Wollastonite, enenkomba yayo ephezulu yokugqama, amandla okumboza aqinile, kanye nokumuncwa kwamafutha aphansi, iyisigcwalisi esisebenzayo sokufaka izinto zokwakha, ukuvikela ukugqwala, ukuvikela amanzi nokungashi. Ingathuthukisa ngempumelelo amandla omshini wokufaka izinto ezifana nokumelana nokuwasha, ukumelana nokuguquka kwesimo sezulu, ukumelana nokuqhekeka, kanye nokumelana nokugoba, kanye nokumelana nokugqwala, ukumelana nesimo sezulu, kanye nokumelana nokushisa. Ifaneleka kakhulu ekukhiqizeni upende omhlophe wekhwalithi ephezulu kanye nopende onombala ocacile nobonakalayo; Ngaphandle kokuthinta ukumbozwa kanye nokugezwa kopende, i-wollastonite ingathatha indawo ye-titanium dioxide engu-20% -30% ohlelweni lopende lwe-latex lwangaphakathi, ithuthukise inani le-pH lohlelo, futhi inciphise izindleko zokukhiqiza zopende.

2. Izinto zobumba
I-Wollastonite ingasetshenziswa kabanzi emikhiqizweni ye-ceramic efana namathayili acwebezelisiwe, izitsha zobumba zansuku zonke, izitsha zobumba ezihlanzekile, izitsha zobumba zobuciko, izitsha zobumba ezikhethekile zokuhlunga, i-ceramic glaze, i-insulating izitsha zobumba zikagesi ezivame kakhulu, izitsha zobumba ezilula, kanye nezitsha zobumba zikagesi. Ingathuthukisa ubumhlophe, ukumuncwa kwamanzi, ukwanda kwe-hygroscopic, kanye nokumelana nokupholisa okusheshayo nokushisa kwemikhiqizo ye-ceramic, okwenza ukubonakala kwemikhiqizo kube bushelelezi futhi kukhanye, ngamandla akhuphukile kanye nokumelana okuhle kwengcindezi. Ngamafuphi, imisebenzi ye-wollastonite kuzitsha zobumba ifaka: ukunciphisa izinga lokushisa lokudubula kanye nokunciphisa umjikelezo wokudubula; Ukunciphisa ukuncipha kokushiswa kanye nokukhubazeka komkhiqizo; Ukunciphisa ukwanda kwe-hygroscopic komzimba oluhlaza kanye nokwanda kokushisa ngesikhathi senqubo yokudubula; Thuthukisa amandla omshini womkhiqizo.

3. Irabha
I-Wollastonite ingathatha indawo yenani elikhulu le-titanium dioxide, ubumba, kanye ne-lithopone ngerabha enombala okhanyayo, idlala indima ethile yokuqinisa futhi ithuthukise ikhono lokumboza ama-colorants amhlophe, idlala indima yokwenza mhlophe. Ikakhulukazi ngemva kokuguqulwa kwezinto eziphilayo, ubuso be-wollastonite abugcini nje ngokuba ne-lipophilicity, kodwa futhi ngenxa yezibopho eziphindwe kabili zama-molecule e-sodium oleate ejenti yokwelapha, ingabamba iqhaza ekuvuvukeni, ithuthukise ukuxhumanisa, futhi ithuthukise kakhulu umphumela wokuqinisa.

4. Ipulasitiki
Ukumelana okuphezulu, ukungaguquguquki kwe-dielectric okuphansi, kanye nokumuncwa kwamafutha okuphansi kwe-wollastonite kwenza izinzuzo zayo embonini yepulasitiki zibe sobala kakhulu kunezinye izinto zamaminerali ezingezona ezensimbi. Ikakhulukazi ngemva kokuguqulwa, ukuhambisana kwe-wollastonite namapulasitiki kuthuthuka kakhulu, okungathuthukisa ngempumelelo izakhiwo zepulasitiki futhi kuqinisekise ukuzinza kokushisa, i-dielectric ephansi, ukumuncwa kwamafutha okuphansi, kanye namandla aphezulu omshini womkhiqizo. Kunganciphisa nezindleko zomkhiqizo. I-Wollastonite isetshenziswa kakhulu ekukhiqizweni kwe-nylon, engathuthukisa amandla okugoba, amandla okudonsa, inciphise ukumuncwa komswakama, futhi ithuthukise ukuzinza kobukhulu.

5. Ukwenza iphepha
I-Wollastonite inenkomba ephezulu yokugqama kanye nobumhlophe obuphezulu, futhi njenge-filler, ingandisa ukungabonakali kanye nobumhlophe bephepha. I-Wollastonite isetshenziswa ekwenzeni iphepha, futhi inethiwekhi ye-wollastonite plant fiber ephumelayo inesakhiwo esinama-microporous, esithuthukisa ukusebenza kokumuncwa kwe-inki kwephepha. Ngesikhathi esifanayo, ngenxa yokushelela okuthuthukisiwe kanye nokucaca okuncishisiwe, yandisa ukuphrinta kwephepha. I-Wollastonite iphazamisa ukubopha kwemicu yezitshalo, okwenza ingabi nandaba nomswakama, inciphise ukujiya kwayo kanye nokuguquguquka kwayo, futhi ikhulisa ukuzinza kobukhulu bephepha. Ngokwezidingo zephepha, inani lokugcwalisa le-wollastonite liyahlukahluka kusuka ku-5% kuya ku-35%. Ubumhlophe, ukuhlakazeka, kanye nokuhleleka kwempuphu ye-wollastonite echotshoziwe ecoliwe kakhulu kuthuthukiswe kakhulu, okungathatha indawo ye-titanium dioxide njengesigcwalisi sephepha.

6. I-slag yokuvikela yensimbi
I-Wollastonite inezici zokuncibilika okuphansi, i-viscosity yokuncibilika ephansi ekushiseni okuphezulu, kanye nokusebenza kahle kokuvikela, futhi isetshenziswa kabanzi ekubunjweni okuqhubekayo kwe-slag yokuvikela. Uma kuqhathaniswa ne-slag yokuvikela engeyona i-wollastonite, i-slag yokuvikela yensimbi esekelwe ku-wollastonite inezinzuzo ezilandelayo: ukusebenza okuzinzile kanye nokuzivumelanisa nezimo okubanzi; Ayinawo amanzi acwebezelayo futhi inokulahlekelwa okuncane ekushiseni; Inamandla amakhulu okumunca nokuncibilikisa izinto ezifakiwe; Izinzile kahle inqubo; Inemisebenzi emihle kakhulu ye-metallurgical; Ihlanzekile kakhulu, inempilo, futhi inobungani nemvelo; Ingathuthukisa ikhwalithi kanye nokusebenza kahle kokukhiqizwa kokubumba okuqhubekayo.

7. Izinto zokungqubuzana
I-Wollastonite inezakhiwo ezifana nenaliti, izinga eliphansi lokunwebeka, kanye nokumelana okuhle kakhulu nokushisa, okwenza kube yindawo efanelekile yokufaka esikhundleni se-asbestos yefayibha emfushane. Izinto zokungqubuzana ezilungiselelwe ngokufaka i-asbestos esikhundleni sayo nge-wollastonite ene-coefficient ephezulu yokungqubuzana zisetshenziswa kakhulu emikhakheni efana nama-brake pads, ama-valve plugs, kanye nama-clutch ezimoto. Ngemva kokuhlola, konke ukusebenza kuhle, futhi ibanga lokubhuleka kanye nokuphila kwenkonzo kuhlangabezana nezidingo ezifanele. Ngaphezu kwalokho, i-wollastonite ingenziwa futhi ibe yi-felt efana ne-mineral wool kanye nezinye izinto ezithatha indawo ye-asbestos ezifana nokufakwa komsindo, okunganciphisa kakhulu ukusetshenziswa kwe-asbestos futhi kuzuzisa ekuvikeleni imvelo kanye nokuqinisekisa impilo yabantu.

8. I-electrode yokushisela
Ukusebenzisa i-wollastonite njengesithako sokumboza ama-electrode okushisela kungasebenza njengesithako sokuncibilikisa kanye nokwengeza ekwenzeni i-slag, kucindezele ukuphuma ngesikhathi sokushisela, kunciphise ukuchaphaza, kuthuthukise ukugeleza kwe-slag, kwenze umthungo wokushisela uhlanzeke futhi ube muhle, futhi kuthuthukise amandla omshini. I-Wollastonite ingaphinde ihlinzeke nge-calcium oxide yokugeleza kwezinduku zokushisela, kuyilapho iletha i-silicon dioxide ukuze ithole i-slag ephezulu ye-alkaline, enganciphisa izikhala ezivuthayo kanye nezinye izinkinga emalungeni. Inani lokwengeza ngokuvamile liyi-10-20%.
