Wollastonite hmoov rau cov ntaub ntawv siv hauv tsev cov khoom siv ceramic txheej kev lag luam metallurgy manufacturing

Kev Piav Qhia Luv:

Hmoov Wollastonite, yog ib yam khoom siv uas muaj ntau yam calcium metasilicate, siv tau ntau yam lag luam vim nws cov khoom siv lub cev thiab tshuaj lom neeg tshwj xeeb. Hauv kev lag luam ceramics, nws ua haujlwm hloov pauv qhov kev ua si. Piv txwv li, cov tuam txhab tsim vuas feem ntau ntxiv 10-15% hmoov wollastonite rau hauv lawv cov qauv. Qhov kev ntxiv no txo qhov nrawm ntawm kev hlawv thaum hlawv txog li 30%, txo qhov tshwm sim ntawm cov kab nrib pleb thiab kev hloov pauv. Yog li ntawd, cov khoom tsim tau nce ntxiv, thiab cov vuas qhia txog kev tawv thiab kev tiv thaiv khawb, ua rau lawv zoo tagnrho rau thaj chaw muaj neeg coob xws li cov khw loj thiab tshav dav hlau.

Hauv kev tsim cov yas, hmoov wollastonite ua haujlwm ua cov khoom siv txhim kho zoo heev. Ib lub tuam txhab muab khoom siv hauv tsheb tau ntxiv 25% hmoov wollastonite rau polypropylene los tsim cov qhov rooj sib txuas uas sib dua. Cov khoom siv hloov kho tsis tsuas yog txhim kho lub zog cuam tshuam los ntawm 40% tab sis kuj txo qhov warpage, ua kom ntseeg tau tias haum zoo thaum sib dhos. Qhov kev tsim kho tshiab no tau pab lub tuam txhab txiav cov nqi tsim khoom los ntawm 18% thaum ua tau raws li cov qauv kev nyab xeeb hauv tsheb nruj.

Cov xim thiab txheej txheej kuj tau txais txiaj ntsig zoo los ntawm cov hmoov wollastonite. Thaum tsim cov xim sab nraud, nws cov qauv siv lead ua ib qho thaiv tiv thaiv dej thiab UV hluav taws xob. Ib qho kev tshawb fawb qhia tau hais tias cov tsev uas muaj cov xim uas muaj 12% hmoov wollastonite tseem khaws tau 80% ntawm lawv cov xim qub tom qab peb xyoos, piv rau tsuas yog 60% rau cov xim ib txwm muaj.

Cov Khoom Qhia Txog Khoom

Cov Cim Npe Khoom

Wollastonite

Cov ntsiab lus:

Wollastonite yog ib qho silicate mineral ib txoj saw hlau, lub ntsiab tivthaiv yog Ca₃Si₃O₉. Triclinic crystal system, feem ntau yog nyob rau hauv daim ntawv ntawm flakes, radial lossis fibrous aggregates. Dawb nrog me ntsis grey. Iav ci, pearl ci ntawm qhov chaw cleavage. Hardness 4.5-5.0 nrog qhov ceev ntawm 2.78-2.91g / cm³Feem ntau tsim tawm hauv thaj chaw metamorphic ntawm cov pob zeb acidic intrusive thiab limestone, nws yog cov khoom siv tseem ceeb ntawm skarn.

Qhov Zoo ntawm Khoom Muag:

Kev lag luam yas:

Hauv kev lag luam yas, hmoov wollastonite tsis yog tsuas yog ua lub luag haujlwm sau xwb, tab sis kuj hloov ib feem ntawm asbestos thiab iav fiber rau cov ntaub ntawv txhawb nqa. Feem ntau yog siv los txhim kho lub zog tensile thiab lub zog flexural thiab txo cov nqi.

Kev lag luam roj hmab:

Hauv kev lag luam roj hmab, wollastonite hmoov yog qhov zoo tagnrho rau roj hmab, tsis yog tsuas yog tuaj yeem txo cov nqi tsim khoom ntawm cov khoom roj hmab, tab sis kuj tuaj yeem txhim kho cov khoom siv roj hmab muab cov haujlwm tshwj xeeb uas roj hmab tsis muaj.

Kev lag luam xim thiab txheej:

Hauv kev lag luam txheej, wollastonite hmoov yog siv los ua cov khoom siv rau cov xim thiab cov txheej, uas tuaj yeem txhim kho cov khoom siv lub cev thiab tshuaj ntawm cov khoom, kev ruaj khov thiab kev tiv thaiv huab cua, txo qhov ci ntawm cov xim, txhim kho lub peev xwm nthuav dav ntawm cov txheej, txo cov kab nrib pleb, thiab tseem tuaj yeem txo cov roj nqus thiab txhim kho kev tiv thaiv corrosion.
