Wollastonite yog calcium inosilicate mineral (CaSiO3) uas yuav muaj me me ntawm cov hlau, magnesium, thiab manganese hloov rau calcium. Wollastonite yog cov ntxhia hauv ntuj nrog ntau yam tshwj xeeb. nws tau dhau los ua ib qho ntawm cov khoom siv dav siv ntau tshaj plaws. Wollastonite tuaj yeem txhim kho kev ua tau zoo ntawm cov khoom, xws li yas, xim thiab txheej, cov khoom siv hauv tsev, kev sib txhuam, ceramics, thiab metallurgical kev lag luam.

Lava pob zeb & Pumice

Lava pob zeb, tseem hu ua pob zeb volcanic, pob zeb pumice, nws qhov ntom ntom yog nyob ib ncig ntawm 0.4-0.85g / cc, lub teeb ntxeem tau ntawm cov kua qaub volcanic pob zeb iav. Nws yog tus cwj pwm los ntawm lub teeb yuag, siab zog, acid tsis kam, corrosion kuj, thiab tsis muaj kuab paug, tsis muaj hluav taws xob thiab lwm yam. Nws yog ib qho zoo tagnrho natural, ntsuab, environmentally khoom.

Pumice yog ib qho hnyav heev, ntxeem tau thiab abrasive khoom thiab nws tau siv nyob rau hauv kev tsim kho thiab kev zoo nkauj kev lag luam. Nws kuj yog siv los ua ib qho abrasive, tshwj xeeb tshaj yog nyob rau hauv polishes thiab pob zeb-ntxuav ris. Muaj kev thov siab rau pumice, tshwj xeeb tshaj yog rau kev lim dej, tshuaj lom neeg pov tseg, cement manufacturing, horticulture thiab kev lag luam tsiaj.

Vermiculite yog hydrous phyllosilicate ntxhia uas ua rau muaj qhov nthuav dav (exfoliation) thaum cua sov. Exfoliation tshwm sim thaum cov ntxhia yog rhuab txaus. Nws yog qhov hnyav heev thiab sib xyaw yooj yim nrog lwm cov nruab nrab. Vermiculite tsim los ntawm huab cua lossis hydrothermal hloov pauv ntawm biotite lossis phlogopite.

Mica yog cov ntxhia hauv ntuj tsim los ntawm potassium, txhuas, hlau, dej thiab magnesium. Mica yog ib txwm tshwm sim thiab tau sau raws li cov zaub mov silicate. Nws yog tsim rau hauv ib lub phaj nyias los yog daim ntawv qauv, nrog cov ntxhia sib txawv thiab cov yam ntxwv zoo sib xws. Mica tuaj yeem tuav nws elasticity thiab toughness txawm nyob rau hauv qhov kub thiab txias, uas yog vim li cas mica yog haum rau siv nyob rau hauv huab cua noo thiab kub tej yam kev mob. Cov ntxhia mica muaj qhov nqus ntawm 2% mus rau 5%.

Calcined kaolin / Kaolin Clay, tseem hu ua Tuam Tshoj Clay, yog cov hmoov dawb uas tsis yog yas. Lub npe "kaolin" yog muab los ntawm "Gaoling" Kaolinite muaj qhov qis qis-swell muaj peev xwm thiab tsis muaj peev xwm sib pauv cation. Nws yog txheej txheej silicate ntxhia. Nws yog mos, hauv av thiab dawb ntxhia, tsim los ntawm cov tshuaj huab cua ntawm aluminium silicateminerals zoo li feldspar.

Calcined China Clay tau siv hauv ceramics, ntawv ua, pleev xim, cov ntaub ntawv refractory thiab roj hmab. Nws yog li no pab tau nyob rau hauv refractory castables thiab rooj tog, thermal rwb thaiv tsev lub cev, tsawg expansion lub cev, permeable ceramic muaj pes tsawg leeg.

Perlite yog amorphous volcanic iav uas muaj cov ntsiab lus dej siab, feem ntau tsim los ntawm hydration ntawm obsidian. Nws tshwm sim ib txwm muaj thiab muaj qhov txawv txav ntawm qhov nthuav dav heev thaum rhuab txaus. Nws yog cov ntxhia hauv kev lag luam thiab cov khoom lag luam muaj txiaj ntsig zoo rau nws qhov ntom ntom tom qab ua tiav.

Perlite pops thaum nws ncav cuag qhov kub ntawm 850-900 ° C (1,560-1,650 ° F). Dej daig nyob rau hauv cov qauv ntawm cov khoom vaporises thiab khiav, thiab qhov no ua rau lub expansion ntawm cov khoom mus rau 7-16 lub sij hawm nws thawj ntim. Cov khoom nthuav dav yog cov ci ntsa iab dawb, vim muaj qhov cuam tshuam ntawm cov npuas npuas. Unexpanded ("raw") perlite muaj qhov ntom ntom ntawm 1100 kg / m3 (1.1 g / cm3), thaum cov perlite nthuav dav muaj qhov ntom ntom ntawm 30-150 kg / m3 (0.03-0.150 g / cm3).

Cenosphere yog ib lub teeb yuag, hollow kheej kheej ua los ntawm silica thiab alumina thiab muaj cov pa los yog inert gas, feem ntau ua raws li cov thee combustion byproduct ntawm thermal fais fab nroj tsuag. Cov xim ntawm cenospheres txawv ntawm grey mus rau yuav luag dawb thiab lawv qhov ceev yog li ntawm 0.4-0.8 g / cm3 (0.014-0.029 lb / cu hauv), uas ua rau lawv muaj kev sib tw zoo.

Cenospheres yog tawv thiab nruj, lub teeb, tsis muaj dej, tsis muaj zog, thiab rwb thaiv tsev. Qhov no ua rau lawv muaj txiaj ntsig zoo nyob rau hauv ntau yam khoom, tshwj xeeb yog fillers.

Cenosphere yam ntxwv: Cov khoom zoo, hollow, lub teeb yuag, siab zog, hnav tsis kam, kub tsis kam, thermal rwb thaiv tsev.
