Wollastonite - pob

Introduction

Duab ntawv Wollastonite, thawj duab ntawv muaj hauv daim ntawv keem tseem ceeb CaSiO3, tau pom tseem ceeb hauv qhov chaw tsim khoom ntau yam los ntawm nws qhov kev ua zauv thiab kev sib thooj siab. Muab npe hu ua William Hyde Wollaston, tus khaub ncaws nyob saum toj no, duab ntawv no muaj txoj hlab zoo li kab roj thiab duab ntawv kab roj, uas pab nws ua haujlwm zoo hauv qhov chaw siv ntau yam. Qhov keeb kwm no muab kev paub meej meej txog duab ntawv Wollastonite, suav nrog nws qhov kev ua zauv, kev siv, thiab kev mob keeb kwm.

Nkws thiab noj kawg

Qhov tshuab Wollastonite feem ntau yooj yim los ntawm dub thiab kab keeb, muaj duab ntxoog lossis duab kab roj. Qhov chaw ntxoog triclinic thiab kab ruaj, nyob rau hauv kab ruaj hlub thiab kab ruaj sib txig sib xig, ua rau nws muaj duab tshwj xeeb. Qhov kev cai tseem ceeb ntawm wollastonite tas li yog 48.25% calcium oxide (CaO) thiab 51.75% silicon dioxide (SiO2). Tab sis, qhov kev pom zoo ntawm wollastonite tsis meej, vim tias calcium feem ntau raug hloov kho los ntawm lwm yam khoom sib thooj ib leeg zoo li iron (Fe), manganese (Mn), titanium (Ti), thiab strontium (Sr), uas pab tau kev sib xyaw. Lawv cov khaub ncaws no, thaum twg tshwm sim hauv qhov chaw tsawg, tuaj yeem muaj kev pab lub zog thiab kev sib thooj ntawm khoob.

Yam ntxwv tshaj plaws hauv qhov chaw ntawm wollastonite powder yog nws lub teb ntau, uas ua rau nws zoo li ib qhov kho thiab ib qhov kho nyiaj ruaj khov rau ntau yam kev siv. Tom qab ntawd, nws tus kheej zoo li kab thiab duv duv muaj feem tshwm sim rau kev txhim kho, pab txhim kho cov zis sib txawv ntawm cov khoom siv nws tau sib thooj. Hauv cheeb koom kim hauv kim, wollastonite tsim nyog hauv qhov loj ntawm pH thiab muaj kev txaus siab tshaj plaws rau kev tso tseg thiab kev puav tswj kim, uas ua rau nws tsim nyog rau kev siv hauv cove.

Kev siv nyob rau hauv ntau hom chaw tsim khoom

• Tsoom Fab Plastics : Wollastonite powder siv ntau yam li ib qhov chaw sau thiab qhov chaw txhim kho rau hauv tso thaiv. Nws tsim cov duab kab rov tav tuaj yeem pab txhim kho kev nyhib thiab kev txhim kho hluv hluv ntawm tso thaiv, thaum kuj txo nqi ntau los ntawm kev pab kho tau ib qhov chaw siv cov roj ntau tshaj. Nws muaj kev siv hauv ntau hom tso thaiv, xws li epoxy, phenolic, thermosetting polyester, thiab polyolefin. Kev ntxig wollastonite tuaj yeem pab txhim kho kev nyob deb zoo, kev txaus siab rau kub, thiab kev nyhib siab dua ntawm tso thaiv, uas ua rau nws raug siv rau hauv cov khoom siv hauv zwm, cov khoom siv hauv dej thiab cov khoom siv hauv neeg.
• Tso thaiv : Nyob hauv qhov chaw tsim kho tshuab rubber, wollastonite powder txhawj xeeb yam li siv los ua filler, zoo tshaj yam ntau lawm, zoo tshaj hluv tshuab. Tom qab muab sau ua ke kom me me thiab hloov kho lub surface, nws tuaj yeem rhuav tus carbon black thiab silica, kom khoom tsim nyog tau nce thiab ceev dua. Rubber uas muaj wollastonite yog tshuab meej ntau dua, tshuab huv siab dua, thiab tshuab ruaj khov dua, zoo tshaj rau kev siv rau feem ntawm rooj xaum, conveyor belts, thiab gaskets.
• Huv Tsim : Xaum li hom siv hauv cov dej nkhaus thiab cov huv, cim wollastonite pab txhim khu qhov kev nyob ib si thiab kev tshwm sim ntawm cov khoom tiav. Nws pab txhim khu kev nyob ib si, kev tiv thaiv kom tsis pub cuam tshuam los ntawm dej thiab av, thiab kev tiv thaiv kom tsis pub ruaj, thaum kheej txo qhov saub thiab pab txhim khu kev kawm ntawm huv. Qhov ob npe tshiab thiab qhov tseem ceeb tshaj plaws ntawm wollastonite ua rau nws tsim nyog rau cov dej nkhaus thiab huv tshiab tshiab. Txij li cas los, qhov chaw nruj tsis ntev ntawm nws pab tiv thaiv kom tsis pub ntxa, nyob ntev dua rau cov khoom uas muaj huv.
• Tus Tshuab Tsau Ntawv : Wollastonite powder pom kev siv nyob rau hauv tus tshuab tsau ntawv ua filler thiab composite fiber. Los yog los substitute ib qhov sib txawv ntawm tus plant fiber, nws txo qhov wood pulp siv, ceev ntau nqi, thiab pab txhim kho cov ntawv. Ntawv uas muaj wollastonite filler muaj kev pab hloov kom zoo dua hauv kev huv, opacity, thiab hom, thaum kuj txo static electricity thiab shrinkage. Cov kev pab hloov no pab kom ntawv zoo dua rau kev sau thiab sau ntawv, thiab rau cov ntawv sib txawv zoo li thermal thiab photographic paper.
• Tus Tshuab Ceramic : Nyob rau hauv tus tshuab ceramic, wollastonite powder raug siv ua flux thiab opacifier, pab txhim kho cov kev sintering thiab huv ntawm cov khoom ceramic. Nws rho qis qhov ua pa, txo kev siv zog, thiab pab txhim kho kev nyob siab meej thiab kev txaus siab ntawm ceramics. Wollastonite feem ntau raug siv nyob rau hauv kev tsau porcelain, sanitary ware, thiab technical ceramics.

Kev Nyob Zeem Zeem

Qhov chaw tsim khoom wollastonite powder hauv lub ntiaj teb muaj kev tshwm sim los ntawm ntau yam cuab yeej, xws li kev cex kom muaj nyiaj los ntawm qhov siv ntau, kev pom zoo ntawm khoom siv, thiab nqi siv los tsim khoom. Qhov chaw tsim kho thiab chaw tsim yeeb yaj yog qhov tseem ceeb tiam sis muaj kev cex kom muaj nyiaj, vim lawv xav tau khoom siv zoo kom ua rau ntau yam kev siv. Qhov kev xav kom muaj kev nyab xeeb thiab khoom siv phem tsis tuaj yeem muaj feem cuam tau pib tso siab dua, vim tias wollastonite yog ib qhov khoob uas nyob ze tib neeg thiab tsis muaj feem cuam ntau rau hauv cheeb kawm.

Txwv tsis pub, qhov chaw tsim khoom muaj kev txwv ceev xws li kev hloov pauv ntawm nqi khoom siv thiab kev sib thauj nrog ntawm cov khoom siv tsim los. Kom nyob deb ntawm kev sib thauj, cov neeg tsim khoom tab tom xav kom tsim khoom wollastonite uas muaj zog siab thiab ntau dua. Tom qab ntawd, kev pib hauv kev kho thiab kev tsim khoom yuav pib tso siab kom muaj khoom zoo dua thiab kom tsawg nqi siv los tsim khoom.

Yav tom ntej

Qhov xeev ntawm qhov chaw tsim kho tshuab wollastonite muaj feem ntau, nrog rau ib co yam ntxwv uas tsim qhov teeb meem. Qhov loj siab txaus siab rau cov khoom siv zoo tshaj plaws hauv kev tsim kho thiab kev siv tshuab ua haujlwm yuav tsum cuam txej kev pib hlo li. Tom qab ntawv, kev kawm paub ntxiv txog kev siv tshuab tshiab, tshpecially hauv kev lag luam aerospace thiab electronics, yuav tsim tau lub sijhawm tshiab rau cov neeg tsim kho wollastonite.

Kev nyob ruaj khov yuav mus ntxiv rau lub npej ntseeg tseem ceeb, nrog rau cov neeg tsim kho kawm siv cov kev ua lag lag khov dav hlau thiab tsim cov khoom zoo rau ntiaj teb. Kev siv wollastonite hauv kev pab kho dej thiab pa, zoo li kev ruaj ntseg hluv thiab kev saj ntsuaj dej, kuj tab tom cuam txej, txhim kho qhov feem ntau ntawm qhov chaw tsim kho.

Nyuv, wollastonite powder yog ib qhov khoob uas muaj ntau yam kev siv nyob rau hauv ntau cheeb tsam. Nws tsim nyog tshwj xeeb hauv kev tshuaj lom neeg thiab kev tshuaj ntiag tug, thiab nrog rau nws tus cwj pwm zoo rau ntiaj teb, ua rau nws yog ib qhov khoom zoo hauv cheeb tsam no. Thaum koj xav tau cov khoom siv zoo thiab khoom siv nyob rau tib neeg rov cuar, lub sijhawm txheej txheem ntawm wollastonite powder yuav tseem ceev.
