Kev ua tau zoo ntawm wollastonite

Wollastonite belongs rau ib leeg saw silicate hom ore, nrog cov mis molecular Ca3 [Si3O9], thiab feem ntau yog nyob rau hauv daim ntawv ntawm fibers, koob, flakes, los yog hluav taws xob.Wollastonite feem ntau yog dawb lossis greyish dawb, nrog rau qee yam luster.Wollastonite muaj ib qho tshwj xeeb siv lead ua morphology, yog li nws muaj kev rwb thaiv tsev zoo, dielectric zog, thiab kub kub thiab huab cua tsis kam.Cov khoom no kuj yog lub hauv paus rau kev txiav txim siab ua lag luam daim ntawv thov ntawm wollastonite.

1. Txheej txheej
Wollastonite, nrog rau nws qhov siab refractive Performance index, muaj zog npog lub zog, thiab cov roj tsawg nqus, yog cov khoom siv ua haujlwm rau lub tsev txheej txheej, tiv thaiv corrosion txheej, waterproof thiab fireproof txheej.Nws tuaj yeem txhim kho lub zog txhua yam ntawm cov txheej txheej xws li ntxuav tsis kam, huab cua tsis kam, tawg tsis kam, thiab khoov tsis kam, nrog rau kev tiv thaiv corrosion, huab cua tsis kam, thiab kub ua haujlwm.Nws yog qhov tshwj xeeb tshaj yog tsim los ua cov xim zoo nkauj dawb thiab cov xim ntshiab thiab pob tshab;Tsis muaj kev cuam tshuam rau kev tiv thaiv thiab kev ntxuav ntawm cov txheej txheem, wollastonite tuaj yeem hloov 20% -30% titanium dioxide nyob rau hauv cov phab ntsa sab hauv phab ntsa latex xim, txhim kho pH tus nqi ntawm cov txheej txheem, thiab txo cov nqi ntawm cov txheej.

2. Ceramics
Wollastonite tuaj yeem siv dav hauv cov khoom siv ceramic xws li cov vuas glazed, niaj hnub ceramics, huv si ceramics, artistic ceramics, tshwj xeeb ceramics rau pom, ceramics glaze, insulating high-frequency electric ceramics, lightweight ceramics, thiab hluav taws xob ceramics.Nws tuaj yeem txhim kho cov xim dawb, dej nqus, hygroscopic nthuav dav, thiab tsis kam ua kom txias thiab cua sov ntawm cov khoom siv ceramic, ua rau cov khoom zoo nkauj smoother thiab ci dua, nrog rau lub zog thiab kev ua haujlwm siab.Hauv cov ntsiab lus, cov haujlwm ntawm wollastonite hauv ceramics suav nrog: txo qhov kub thiab txias thiab ua kom lub voj voog hluav taws xob luv;Txo sintering shrinkage thiab cov khoom tsis xws luag;Txo cov hygroscopic expansion ntawm lub cev ntsuab thiab thermal expansion thaum lub sij hawm tua;Txhim kho lub zog txhua yam ntawm cov khoom.

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

4. Yas
Kev ua haujlwm siab, tsis tshua muaj hluav taws xob tsis tu ncua, thiab cov roj tsawg nqus ntawm wollastonite ua rau nws qhov zoo hauv kev lag luam yas ntau pom tseeb dua li lwm cov khoom siv hlau tsis yog hlau.Tshwj xeeb tshaj yog tom qab kev hloov kho, kev sib raug zoo ntawm wollastonite nrog plastics tau zoo heev, uas tuaj yeem txhim kho cov khoom yas zoo thiab ua kom cov thermal stability, tsis tshua muaj dielectric, tsis muaj roj nqus, thiab lub zog txhua yam ntawm cov khoom.Nws kuj tuaj yeem txo tus nqi ntawm cov khoom.Wollastonite feem ntau yog siv rau hauv kev tsim cov nylon, uas tuaj yeem txhim kho khoov lub zog, tensile lub zog, txo qhov nqus dej, thiab txhim kho qhov ruaj khov.

5. Ntawv ua
Wollastonite muaj siab refractive Performance index thiab siab whiteness, thiab raws li ib tug muab tub lim, nws yuav ua rau kom cov opacity thiab whiteness ntawm daim ntawv.Wollastonite yog siv hauv papermaking, thiab cov txiaj ntsig wollastonite cog fiber ntau network muaj cov qauv microporous ntau dua, uas txhim kho cov cwj mem nqus ntawm daim ntawv.Nyob rau tib lub sijhawm, vim kev txhim kho smoothness thiab txo cov pob tshab, nws ua rau kom cov ntawv luam tawm ntau dua.Wollastonite cuam tshuam nrog kev sib txuas ntawm cov nroj tsuag fibers, ua rau lawv tsis hnov ​​​​tsw rau cov av noo, txo lawv cov hygroscopicity thiab deformation, thiab ua rau kom qhov seem stability ntawm daim ntawv.Raws li daim ntawv xav tau, qhov ntim ntawm wollastonite txawv ntawm 5% mus rau 35%.Lub whiteness, dispersibility, thiab leveling ntawm ultrafine crushed wollastonite hmoov tau zoo heev, uas tuaj yeem hloov titanium dioxide ua daim ntawv muab tub lim.

6. Metallurgical tiv thaiv slag
Wollastonite muaj cov yam ntxwv ntawm qhov qis melting point, tsis tshua muaj kub melting viscosity, thiab zoo rwb thaiv tsev kev ua tau zoo, thiab yog dav siv nyob rau hauv nruam casting tiv thaiv slag.Piv nrog rau cov uas tsis yog wollastonite tiv thaiv slag, metallurgical tiv thaiv slag raws li wollastonite muaj qhov zoo hauv qab no: kev ua haujlwm ruaj khov thiab dav adaptability;Nws tsis muaj cov dej crystalline thiab muaj qhov poob qis ntawm ignition;Nws muaj peev xwm adsorb thiab yaj inclusions;Muaj kev ruaj ntseg zoo;Nws muaj kev ua haujlwm zoo heev ntawm metallurgy;Ntau yam huv si, noj qab nyob zoo, thiab ib puag ncig tus phooj ywg;Nws tuaj yeem txhim kho qhov zoo thiab ua haujlwm ntawm kev nruam casting ntau lawm.

7. Cov khoom sib txhuam
Wollastonite muaj rab koob zoo li lub zog, qis qis qis, thiab zoo heev thermal shock resistance, ua rau nws zoo tagnrho hloov rau luv fiber ntau asbestos.Cov ntaub ntawv sib txhuam uas tau npaj los ntawm kev hloov cov asbestos nrog kev sib txhuam coefficient wollastonite yog siv rau hauv thaj chaw xws li nres, valve plugs, thiab tsheb clutches.Tom qab kev sim, tag nrho cov kev ua tau zoo yog zoo, thiab lub braking nrug thiab kev pab cuam lub neej raws li qhov yuav tsum tau muaj.Tsis tas li ntawd, wollastonite tseem tuaj yeem ua rau muaj kev xav zoo li cov ntaub plaub ntxhia pob zeb thiab ntau yam khoom siv asbestos xws li suab rwb thaiv tsev, uas tuaj yeem txo qis 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 los ua cov txheej txheem rau vuam electrodes tuaj yeem ua cov khoom siv yaj thiab cov slag ua cov khoom ntxiv, tshem tawm tawm thaum lub sij hawm vuam, txo cov txaws, txhim kho slag fluidity, ua kom lub vuam seam huv si thiab zoo nkauj, thiab txhim kho cov neeg kho tshuab lub zog.Wollastonite kuj tseem tuaj yeem muab cov calcium oxide rau cov dej ntws ntawm cov welding rods, thaum nqa hauv silicon dioxide kom tau cov alkaline slag siab, uas tuaj yeem txo qhov kub hnyiab thiab lwm yam tsis xws luag ntawm cov pob qij txha.Qhov nyiaj ntxiv yog feem ntau 10-20%.
