Wollastonite hmoov, ib qho calcium metasilicate mineral uas muaj nyob hauv ntuj tsim uas tau txais kev qhuas rau nws cov qauv acicular (zoo li koob), qhov dawb zoo kawg nkaus, thiab kev ruaj khov ntawm tshuaj lom neeg, tau ua kom nws txoj haujlwm ua ib qho khoom siv ntau yam tseem ceeb hauv ntau yam kev lag luam thoob ntiaj teb. Cov mineral no pheej yig ua rau kev ua haujlwm zoo dua, txo cov nqi, thiab txhawb nqa kev tsim khoom ruaj khov hauv cov khoom siv ceramics, plastics, coatings, kev tsim kho, thiab metallurgy.

Cov Kev Siv Hauv Kev Lag Luam Tseem Ceeb

Hauv kev lag luam ceramics, wollastonite ua tus hloov pauv kev ua si. Nws txo qhov kub ntawm kev hlawv los ntawm 100–200°C, txo kev siv hluav taws xob, thiab ua kom lub voj voog tua hluav taws luv dua. Qhov kev ua haujlwm fluxing no ua rau cov glaze ci ntsa iab, ua kom cov khoom siv ceramic muaj zog, thiab txo cov qhov tsis zoo xws li tawg thiab warping hauv cov vuas, cov khoom siv huv, thiab cov khoom siv porcelain.

Rau cov yas thiab cov polymers, nws qhov sib piv siab (10: 1+) muab kev txhawb nqa zoo kawg nkaus. Nws txhim kho lub zog tensile, flexural modulus, tiv taus cua sov, thiab dimensional stability hauv PP, PE, nylon, thiab PVC. Kev kho qhov chaw (piv txwv li, silane KH-570) ua kom zoo dua qhov sib xws ntawm polymer, ua rau nws zoo tagnrho rau cov khoom siv tsheb thiab cov khoom ua tau zoo.

Hauv cov xim thiab cov txheej txheej, wollastonite ua haujlwm ua cov xim txuas ntxiv. Nws txo cov kev siv titanium dioxide kim thaum txhim kho kev ruaj khov, kev tiv thaiv corrosion, thiab kev tiv thaiv UV. Nws qhov kev nqus roj tsawg thiab qhov ci ntsa iab ua rau cov xim tiav du thiab khaws cov xim zoo heev.

Cov kev lag luam tsim kho thiab metallurgy suav tias wollastonite yog siv los ua cov pob zeb ua kom ruaj khov, tsim cov laug cam uas tiv taus hluav taws, thiab ua cov pwm ua kom huv si. Nws kuj tseem hloov cov asbestos hauv cov ntaub ntawv sib txhuam xws li cov ntaub nres.

Cov Lus Qhia Txog Kev Siv & Kev Ceev Faj

Cov Kev Siv:

Yas: Sib xyaw 5–30% kho wollastonite los ntawm kev rho tawm; ua kom zoo dua rau qhov sib piv.

Cov Khoom Siv Ua Los Ntawm Av nplaum: Sib xyaw 10–40% hmoov zoo (325)–1250 mesh) rau hauv cov khoom nyoos.

Cov txheej txheem: Ntxiv thaum lub sijhawm sib tov rau kev sib kis sib xws.

Kev Nyab Xeeb & Kev Tswj:

Khaws cia rau hauv qhov chaw qhuav, kaw kom tsis txhob muaj dej noo.

Siv cov ntaub npog qhov ncauj thiab hnab looj tes; xyuas kom muaj cua nkag tau zoo.

Tsis txhob kov daim tawv nqaij ntev; ntxuav nrog dej yog tias raug.

Thaum cov lag luam muab qhov tseem ceeb rau kev ruaj khov thiab kev ua haujlwm zoo, qhov kev thov ntawm cov hmoov wollastonite nce siab. Nws qhov kev sib xyaw ua ke ntawm kev txhawb nqa, kev ntws, thiab kev ruaj khov ua rau nws lub luag haujlwm ua cov khoom siv tseem ceeb rau kev tsim khoom niaj hnub, kev xav txog ib puag ncig.
