Iimpawu zokusebenza kwe-wollastonite

I-Wollastonite yeyesilicate yohlobo lwe-single chain, ene-molecular formula Ca3 [Si3O9], kwaye ngokubanzi ikwimo yeefayibha, iinaliti, iiflakes, okanye i-radiation. I-Wollastonite ikakhulu imhlophe okanye ingwevu emhlophe, inokukhanya okuthile. I-Wollastonite ine-crystal morphology eyahlukileyo, ngoko ke ine-insulation elungileyo, iipropati ze-dielectric, kunye nokumelana nobushushu obuphezulu kunye nemozulu. Ezi mpawu zikwasisiseko sokumisela ukusetyenziswa kwe-wollastonite kwimarike.

1. Iingubo zokwaleka
I-Wollastonite, ene-refractive index yayo ephezulu, amandla okugquma aqinileyo, kunye nokufunxwa kweoyile okuphantsi, sisixhobo sokuzalisa esisebenzayo kwi-coatings zokwakha, i-anti-corrosion coatings, i-coatings ezingangeni manzi nezingatshiyo. Ingaphucula ngempumelelo amandla oomatshini e-coatings afana nokumelana nokuhlanjwa, ukumelana nokuguquka kwemozulu, ukumelana nokuqhekeka, kunye nokumelana nokugoba, kunye nokumelana nokugqwala, ukumelana nemozulu, kunye nokumelana nobushushu. Ifanelekile ngokukodwa ukuvelisa ipeyinti emhlophe esemgangathweni ophezulu kunye nepeyinti enemibala ecacileyo necacileyo; Ngaphandle kokuchaphazela ukugqunywa kunye nokuhlanjwa kwe-coatings, i-wollastonite inokuthatha indawo ye-20% -30% titanium dioxide kwinkqubo yepeyinti ye-latex eludongeni lwangaphakathi, iphucule ixabiso le-pH yenkqubo, kwaye inciphise iindleko zemveliso ye-coatings.

2. Iiseramikhi
I-Wollastonite ingasetyenziswa kakhulu kwiimveliso zeseramikhi ezifana neethayile ezifakwe iglasi, iiseramikhi zemihla ngemihla, iiseramikhi zococeko, iiseramikhi zobugcisa, iiseramikhi ezikhethekileyo zokucoca, i-ceramic glaze, i-insulating iiseramikhi zombane ezisebenzisa i-high-frequency, ii-ceramic molds ezilula, kunye neeseramikhi zombane. Ingaphucula ubumhlophe, ukufunxwa kwamanzi, ukwanda kwe-hygroscopic, kunye nokumelana nokuphola ngokukhawuleza kunye nokufudumeza kweemveliso zeseramikhi, okwenza ukubonakala kweemveliso kube lula kwaye kukhanye, ngamandla anyukileyo kunye nokumelana okuhle koxinzelelo. Ngamafutshane, imisebenzi ye-wollastonite kwiiseramikhi ibandakanya: ukunciphisa ubushushu bokudubula kunye nokunciphisa umjikelo wokudubula; Ukunciphisa ukushwabana kwe-sintering kunye neziphene zemveliso; Ukunciphisa ukwanda kwe-hygroscopic yomzimba oluhlaza kunye nokwanda kobushushu ngexesha lenkqubo yokudubula; Ukuphucula amandla oomatshini emveliso.

3. Irabha
I-Wollastonite inokuthatha indawo yesixa esikhulu se-titanium dioxide, udongwe, kunye ne-lithopone ngerabha enemibala ekhanyayo, idlala indima ethile yokuqinisa kunye nokuphucula amandla okugubungela imibala emhlophe, idlala indima yokwenza mhlophe. Ingakumbi emva kokuguqulwa kwezinto eziphilayo, umphezulu we-wollastonite awunayo kuphela i-lipophilicity, kodwa ngenxa yeebhondi eziphindwe kabini zeemolekyuli ze-sodium oleate zearhente yonyango, inokuthatha inxaxheba kwi-vulcanization, iphucule ukudibana, kwaye iphucule kakhulu isiphumo sokuqinisa.

4. Iplastiki
Ukumelana okuphezulu, ukungaguquguquki kwe-dielectric ephantsi, kunye nokufunxwa kweoyile ephantsi kwe-wollastonite kwenza iingenelo zayo kushishino lweplastiki zibonakale ngakumbi kunezinye izinto zeminerali ezingezizo ezesinyithi. Ingakumbi emva kokuguqulwa, ukuhambelana kwe-wollastonite neeplastiki kuphuculwe kakhulu, okunokuphucula ngempumelelo iipropati zeplastiki kwaye kuqinisekise uzinzo lobushushu, i-dielectric ephantsi, ukufunxwa kweoyile ephantsi, kunye namandla aphezulu oomatshini emveliso. Inganciphisa neendleko zemveliso. I-Wollastonite isetyenziswa kakhulu ekuveliseni i-nylon, enokuphucula amandla okugoba, amandla okutsalwa, ukunciphisa ukufunxwa komswakama, kunye nokuphucula uzinzo olunemilinganiselo.

5. Ukwenza iphepha
I-Wollastonite ine-refractive index ephezulu kunye nomhlophe ophezulu, kwaye njenge-filler, inokunyusa ukungabonakali kunye nomhlophe wephepha. I-Wollastonite isetyenziswa ekwenzeni iphepha, kwaye inethiwekhi ye-wollastonite plant fiber ephumayo inesakhiwo esine-microporous ngakumbi, nto leyo ephucula ukusebenza kwe-inki yephepha. Kwangaxeshanye, ngenxa yokuthamba okuphuculweyo kunye nokukhanya okunciphileyo, inyusa ukuprintwa kwephepha. I-Wollastonite iphazamisa ukubopha kweefayibha zezityalo, izenze zingabi namvakalelo kumswakama, inciphisa i-hygroscopicity yazo kunye nokuguquguquka kwazo, kwaye inyusa uzinzo lobukhulu bephepha. Ngokweemfuno zephepha, ubungakanani bokuzalisa be-wollastonite buyahluka ukusuka kwi-5% ukuya kwi-35%. Ubumhlophe, ukusasazeka, kunye nokulinganiswa komgubo we-wollastonite ocoliweyo ocoliweyo ocoliweyo kuphuculwe kakhulu, okunokuthatha indawo ye-titanium dioxide njengesizalisi sephepha.

6. I-slag yokukhusela ye-Metallurgical
I-Wollastonite ineempawu zokuba yindawo yokunyibilika ephantsi, i-viscosity yokunyibilika ephantsi yobushushu obuphezulu, kunye nokusebenza kakuhle kobushushu, kwaye isetyenziswa kakhulu kwi-slag ekhuselayo yokuphosa ngokuqhubekayo. Xa kuthelekiswa ne-slag ekhuselayo engeyiyo i-wollastonite, i-slag ekhuselayo ye-metallurgical esekelwe kwi-wollastonite inezi nzuzo zilandelayo: ukusebenza okuzinzileyo kunye nokuzivumelanisa nokuguquguquka ngokubanzi; Ayinamanzi acwebezelayo kwaye ayinalahleko ingako ekutshiseni; Inamandla okufunxa nokunyibilikisa izinto ezifakiweyo; Izinzile kwinkqubo elungileyo; Inomsebenzi ogqwesileyo we-metallurgical; Icocekile ngakumbi, isempilweni, kwaye inobuhlobo nokusingqongileyo; Ingaphucula umgangatho kunye nokusebenza kakuhle kwemveliso yokuphosa ngokuqhubekayo.

7. Izinto zokungqubana
I-Wollastonite ineempawu ezifana nenaliti, isantya sokwanda esiphantsi, kunye nokumelana okuhle kakhulu nobushushu, okwenza ukuba ibe yindawo efanelekileyo yokuthatha indawo ye-asbestos yefayibha emfutshane. Izinto zokungqubana ezilungiselelwe ngokuthatha indawo ye-asbestos nge-wollastonite ene-coefficient ephezulu yokungqubana zisetyenziswa kakhulu kwiindawo ezifana nee-brake pads, ii-valve plugs, kunye nee-automotive clutches. Emva kovavanyo, yonke imisebenzi ilungile, kwaye umgama wokubhuleka kunye nobomi benkonzo ziyahlangabezana neemfuno ezifanelekileyo. Ukongeza, i-wollastonite inokwenziwa ibe yi-felt efana ne-mineral wool kunye nezinye izinto ezahlukeneyo ze-asbestos ezifana ne-sound insulation, ezinokunciphisa kakhulu ukusetyenziswa kwe-asbestos kwaye ziluncedo ekukhuseleni okusingqongileyo nasekuqinisekiseni impilo yabantu.

8. I-electrode yokuwelda
Ukusebenzisa i-wollastonite njengesithako sokugquma kwii-electrode zokuwelda kunokusebenza njengoncedo lokunyibilika kunye nokongeza ekwenzeni i-slag, kuthintele ukukhupha ngexesha lokuwelda, kunciphise ukutshiza, kuphucule ukugeleza kwe-slag, kwenze umthungo we-weld ucoceke kwaye ube mhle, kwaye kuphucule amandla oomatshini. I-Wollastonite inokubonelela nge-calcium oxide yokujikeleza kweentonga zokuwelda, ngelixa izisa i-silicon dioxide ukuze ifumane i-alkaline slag ephezulu, enokunciphisa ii-pores ezitshayo kunye nezinye iziphene kwiindawo zokujola. Ubungakanani bokongeza ngokubanzi yi-10-20%.
