Ufa wa Wollastonite, mchere wachilengedwe wa calcium metasilicate womwe umadziwika chifukwa cha kapangidwe kake kapadera konga singano (kofanana ndi singano), kuyera kwake kwapadera, komanso kukhazikika kwa mankhwala, walimbitsa malo ake ngati chodzaza chofunikira kwambiri m'mafakitale osiyanasiyana padziko lonse lapansi. Mchere wotsika mtengo uwu umathandizira magwiridwe antchito, umachepetsa ndalama, komanso umathandizira kupanga zinthu zokhazikika mu zoumbaumba, mapulasitiki, zokutira, zomangamanga, ndi zitsulo.

Mapulogalamu Ofunika Kwambiri a Mafakitale

Mu gawo la zoumbaumba, wollastonite imasintha zinthu. Imachepetsa kutentha kwa moto ndi 100–200°C, imachepetsa kugwiritsa ntchito mphamvu, ndipo imachepetsa nthawi yozimitsira moto. Kuchita izi kumawonjezera kuwala kwa glaze, kumalimbitsa matupi a ceramic, komanso kumachepetsa kwambiri zolakwika monga ming'alu ndi kupindika kwa matailosi, ziwiya zaukhondo, ndi porcelain.

Pa mapulasitiki ndi ma polima, chiŵerengero chake chapamwamba (10:1+) chimapereka mphamvu yodabwitsa. Chimawongolera kwambiri mphamvu yokoka, kusinthasintha kwa flexural modulus, kukana kutentha, komanso kukhazikika kwa PP, PE, nayiloni, ndi PVC. Kukonza pamwamba (monga silane KH-570) kumawongolera kuyanjana kwa polima, ndikupangitsa kuti ikhale yoyenera kwambiri pazida zamagalimoto ndi zida zogwirira ntchito bwino.

Mu utoto ndi zokutira, wollastonite imagwira ntchito ngati utoto wowonjezera. Imachepetsa kugwiritsa ntchito titanium dioxide yokwera mtengo pomwe imalimbitsa kulimba, kukana dzimbiri, komanso kuteteza UV. Kuchepa kwa mafuta ake komanso kuwala kwake kwakukulu kumatsimikizira kuti utoto wake ndi wosalala komanso kuti mitundu yake ikhale yosalala.

Magawo a zomangamanga ndi zitsulo amaona kuti wollastonite ndi yofunika kwambiri polimbitsa konkriti, kupanga mabolodi osapsa ndi moto, komanso ngati njira yopangira nkhungu yoyera kwambiri. Imagwiranso ntchito m'malo mwa asbestos m'zinthu zokangana monga ma brake pads.

Malangizo Ogwiritsira Ntchito ndi Zotetezera

Njira Zogwiritsira Ntchito:

Mapulasitiki: Blend 5–Wollastonite yokonzedwa ndi 30% kudzera mu extrusion; konzani kuti igwirizane ndi chiŵerengero cha mbali.

Zoumbaumba: Sakanizani 10–Ufa wabwino kwambiri wa 40% (325)–1250 mesh) m'magulu osaphika.

Zophimba: Onjezani mukamasakaniza kuti mufalikire mofanana.

Chitetezo ndi Kusamalira:

Sungani pamalo ouma komanso otsekedwa bwino kuti mupewe kuipitsidwa ndi chinyezi.

Gwiritsani ntchito zophimba fumbi ndi magolovesi; onetsetsani kuti mpweya ukuyenda bwino.

Pewani kukhudzana ndi khungu kwa nthawi yayitali; sambani ndi madzi ngati mwaiona.

Pamene mafakitale akuika patsogolo kukhazikika ndi kugwira ntchito bwino, kufunikira kwa ufa wa wollastonite kukuwonjezeka. Kuphatikiza kwake kwapadera kwa mphamvu zolimbitsa, kusintha, ndi kukhazikika kumalimbitsa ntchito yake ngati maziko opangira zinthu zamakono komanso zosamalira chilengedwe.
