Cov hmoov no nqus roj tsawg thiab txo cov khoom siv sib txuas, txo cov nqi tsim khoom thaum tseem tswj tau kev ua haujlwm ntawm cov txheej pleev xim. Nws kuj ua rau kev lo rau ntau yam khoom siv, ua rau lub neej ntawm cov txheej pleev xim ntev dua.Kev siv hauv kev lag luam ntawv suav nrog kev txhim kho qhov du thiab yooj yim luam tawm ntawm cov ntawv coated. Nws qhov xwm txheej inert ua kom sib xws nrog lwm cov khoom ntxiv, thaum cov khoom me me ua rau muaj kev sib kis sib xws.Hmoov wollastonite qib kev lag luam ua tau raws li cov qauv kev huv huv nruj, nrog rau qib tsis muaj kuab paug tsawg uas ua kom muaj kev ua haujlwm zoo tas li. Nws cov tshuaj lom neeg tsis muaj zog ua rau nws tsim nyog rau cov ntawv thov uas xav tau kev tiv taus cov kua qaub thiab alkalis, ntxiv kev ua tau zoo rau cov txheej txheem tsim khoom. -
Wollastonite hmoov rau cov ntaub ntawv siv hauv tsev cov khoom siv ceramic txheej kev lag luam metallurgy manufacturing
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 hmoov wollastonite dawb zoo rau cov khoom siv hauv kev lag luam pleev xim
Hmoov Wollastonite, yog ib hom calcium-inosilicate mineral, muaj cov qauv siv lead ua zoo li koob lossis fibrous. Cov qauv tshwj xeeb no ua rau nws muaj cov khoom siv kho tshuab thiab lub cev zoo heev, ua rau nws muaj nqis heev rau ntau yam lag luam.Hauv kev lag luam yas, hmoov wollastonite ua haujlwm ua cov khoom siv txhawb zog. Thaum ntxiv rau cov yas, nws ua rau lawv lub zog tensile, flexural modulus, thiab dimensional stability zoo dua. Qhov no ua rau cov khoom yas ruaj khov dua, tiv taus cua sov, thiab haum rau cov ntawv thov xws li cov khoom siv tsheb, cov khoom siv hluav taws xob, thiab cov khoom siv hauv tsev.
Hauv kev lag luam xim thiab txheej, hmoov wollastonite txhim kho lub zog zais, tiv taus huab cua, thiab tiv taus khawb ntawm cov xim. Nws kuj pab tiv thaiv cov xim kom tsis txhob lo rau, ua kom cov xim thiab cov qauv sib xws. Yog li ntawd, nws siv rau hauv ntau hom txheej, los ntawm cov xim tsev sab nraud mus rau cov txheej txheem kev lag luam zoo.
