Cov yam ntxwv ntawm kev ua tau zoo ntawm wollastonite

Wollastonite yog ib hom pob zeb silicate uas muaj cov mis molecular Ca3 [Si3O9], thiab feem ntau yog cov fibers, koob, flakes, lossis hluav taws xob. Wollastonite feem ntau yog dawb lossis greyish dawb, nrog rau qee qhov ci ntsa iab. Wollastonite muaj cov qauv siv lead ua tshwj xeeb, yog li nws muaj kev rwb thaiv tsev zoo, cov khoom dielectric, thiab kub thiab huab cua tiv taus. Cov khoom no kuj yog lub hauv paus rau kev txiav txim siab txog kev siv wollastonite hauv kev lag luam.

1. Cov txheej txheem
Wollastonite, nrog nws cov refractive index siab, muaj zog npog, thiab tsis nqus roj, yog ib qho khoom siv rau kev tsim kho tsev, tiv thaiv xeb, tiv thaiv dej thiab tiv thaiv hluav taws. Nws tuaj yeem txhim kho lub zog kho tshuab ntawm cov txheej xws li kev tiv thaiv ntxuav, tiv thaiv huab cua, tiv thaiv tawg, thiab tiv thaiv khoov, nrog rau kev tiv thaiv xeb, tiv thaiv huab cua, thiab tiv thaiv kub. Nws yog qhov tshwj xeeb tshaj yog rau kev tsim cov xim dawb zoo thiab cov xim ntshiab thiab pob tshab; Tsis cuam tshuam rau kev npog thiab kev ntxuav ntawm cov txheej, wollastonite tuaj yeem hloov 20% -30% titanium dioxide hauv cov xim pleev xim latex sab hauv phab ntsa, txhim kho tus nqi pH ntawm lub kaw lus, thiab txo tus nqi tsim khoom ntawm cov txheej.

2. Cov Khoom Siv Ua Los Ntawm Av nplaum
Wollastonite siv tau dav hauv cov khoom siv ceramic xws li cov vuas glazed, cov khoom siv ceramic niaj hnub, cov khoom siv ceramic huv, cov khoom siv ceramic kos duab, cov khoom siv ceramic tshwj xeeb rau kev lim dej, cov khoom siv ceramic glaze, cov khoom siv hluav taws xob siab zaus, cov pwm ceramic sib dua, thiab cov khoom siv hluav taws xob ceramic. Nws tuaj yeem txhim kho qhov dawb, kev nqus dej, kev nthuav dav hygroscopic, thiab kev tiv taus kev txias thiab cua sov sai ntawm cov khoom siv ceramic, ua rau cov khoom zoo nkauj dua thiab ci dua, nrog rau lub zog ntxiv thiab kev tiv taus siab zoo. Hauv kev xaus, cov haujlwm ntawm wollastonite hauv cov khoom siv ceramic suav nrog: txo qhov kub ntawm kev tua hluav taws thiab luv lub voj voog tua hluav taws; Txo qhov sintering shrinkage thiab cov khoom tsis zoo; Txo qhov hygroscopic nthuav dav ntawm lub cev ntsuab thiab qhov nthuav dav thermal thaum lub sijhawm tua hluav taws; Txhim kho lub zog kho tshuab ntawm cov khoom.

3. Roj Hmab
Wollastonite tuaj yeem hloov cov titanium dioxide, av nplaum, thiab lithopone ntau hauv cov roj hmab xim dawb, ua lub luag haujlwm txhawb nqa thiab txhim kho lub peev xwm npog ntawm cov xim dawb, ua lub luag haujlwm ua kom dawb. Tshwj xeeb tshaj yog tom qab kev hloov pauv organic, qhov chaw ntawm wollastonite tsis yog tsuas yog muaj lipophilicity, tab sis kuj vim yog ob qho kev sib txuas ntawm cov neeg sawv cev kho sodium oleate molecules, nws tuaj yeem koom nrog vulcanization, txhim kho kev sib txuas, thiab txhim kho cov nyhuv txhawb nqa.

4. Yas
Qhov kev tiv taus siab, dielectric tsis tu ncua qis, thiab kev nqus roj tsawg ntawm wollastonite ua rau nws cov txiaj ntsig hauv kev lag luam yas pom tseeb dua li lwm cov khoom siv tsis yog hlau. Tshwj xeeb tshaj yog tom qab hloov kho, qhov sib xws ntawm wollastonite nrog cov yas tau txhim kho zoo heev, uas tuaj yeem txhim kho cov khoom yas thiab xyuas kom meej tias muaj kev ruaj khov thermal, dielectric qis, kev nqus roj tsawg, thiab lub zog kho tshuab siab ntawm cov khoom. Nws kuj tseem tuaj yeem txo tus nqi ntawm cov khoom. Wollastonite feem ntau yog siv rau hauv kev tsim cov nylon, uas tuaj yeem txhim kho lub zog khoov, lub zog tensile, txo qhov nqus dej noo, thiab txhim kho qhov ruaj khov ntawm qhov ntev.

5. Kev ua ntawv
Wollastonite muaj cov ntsuas refractive siab thiab dawb siab, thiab ua ib qho khoom sau, nws tuaj yeem ua rau kom daim ntawv opacity thiab dawb. Wollastonite siv rau hauv kev ua ntawv, thiab cov wollastonite cog fiber network muaj cov qauv microporous ntau dua, uas txhim kho kev ua haujlwm nqus number case ntawm daim ntawv. Tib lub sijhawm, vim yog qhov du thiab tsis pom tseeb, nws ua rau daim ntawv luam tawm ntau dua. Wollastonite cuam tshuam rau kev khi ntawm cov nroj tsuag fibers, ua rau lawv tsis hnov ​​​​​​mob rau cov av noo, txo lawv cov hygroscopicity thiab deformation, thiab ua rau kom muaj kev ruaj khov ntawm daim ntawv. Raws li cov ntawv xav tau, qhov ntim ntawm wollastonite sib txawv ntawm 5% txog 35%. Qhov dawb, dispersibility, thiab leveling ntawm ultrafine crushed wollastonite hmoov tau zoo dua, uas tuaj yeem hloov titanium dioxide ua ib daim ntawv sau.

6. Cov hlau nplaum tiv thaiv
Wollastonite muaj cov yam ntxwv ntawm qhov melting qis, viscosity qis kub siab, thiab kev ua haujlwm rwb thaiv tsev zoo, thiab siv dav hauv kev tiv thaiv casting tas mus li. Piv nrog rau cov slag tiv thaiv uas tsis yog wollastonite, cov slag tiv thaiv metallurgical raws li wollastonite muaj cov txiaj ntsig hauv qab no: kev ua haujlwm ruaj khov thiab kev hloov pauv dav; Nws tsis muaj dej crystalline thiab muaj qhov poob qis ntawm kev hluav taws xob; Muaj peev xwm muaj zog los nqus thiab yaj cov khoom suav nrog; Muaj kev ruaj khov ntawm cov txheej txheem; Muaj cov haujlwm metallurgical zoo heev; Huv dua, noj qab haus huv, thiab tus phooj ywg ib puag ncig; Nws tuaj yeem txhim kho qhov zoo thiab kev ua haujlwm ntawm kev tsim khoom tas mus li.

7. Cov khoom siv sib txhuam
Wollastonite muaj cov khoom zoo li koob, qhov nrawm qis, thiab tiv taus cua sov zoo heev, ua rau nws yog qhov hloov pauv zoo tshaj plaws rau cov asbestos luv luv. Cov ntaub ntawv sib txhuam uas tau npaj los ntawm kev hloov asbestos nrog cov coefficient sib txhuam siab wollastonite feem ntau yog siv rau hauv cov teb xws li cov ntaub nres, cov ntsaws valve, thiab cov clutches tsheb. Tom qab sim, txhua qhov kev ua tau zoo yog qhov zoo, thiab qhov deb nres thiab lub neej ua haujlwm tau raws li qhov yuav tsum tau ua. Tsis tas li ntawd, wollastonite kuj tseem tuaj yeem ua rau cov ntaub plaub zoo li cov pob zeb hauv av thiab ntau yam asbestos hloov xws li kev rwb thaiv tsev suab, uas tuaj yeem txo qhov kev siv asbestos thiab muaj txiaj ntsig zoo rau kev tiv thaiv ib puag ncig thiab ua kom tib neeg noj qab haus huv.

8. Vuam electrode
Siv wollastonite ua cov khoom xyaw rau cov electrodes vuam tuaj yeem ua haujlwm ua cov khoom pab yaj thiab cov khoom ntxiv rau kev ua slag, txo qhov tso tawm thaum vuam, txo qhov splashing, txhim kho slag fluidity, ua rau lub weld seam huv si thiab zoo nkauj, thiab txhim kho lub zog kho tshuab. Wollastonite kuj tseem tuaj yeem muab calcium oxide rau cov flux ntawm cov pas nrig vuam, thaum coj silicon dioxide los kom tau txais cov alkaline slag siab, uas tuaj yeem txo cov qhov kub hnyiab thiab lwm yam tsis zoo ntawm cov pob qij txha. Tus nqi ntxiv feem ntau yog 10-20%.
