Silicon calcium nrog cov yam ntxwv tshwj xeeb

Cacium silicon, tseem hu ua calcium silicon, muaj cov tshuaj muaj tshuaj lom neeg ntawm Casio3 thiab yog ib qho dawb lossis grey ntxhia. Calcium silicon alloy yog ib qho tseem ceeb alloy cov khoom siv, feem ntau muaj 22 ~ 35% calcium thiab 60 ~ 65% silicon. Calcium silicon tuaj yeem faib ua ntau hom sib txawv raws li nws cov qauv siv lead ua thiab tshuaj muaj pes tsawg leeg. Calcium silicon yog insoluble hauv dej, tab sis tuaj yeem yaj nyob hauv cov kua qaub acidic. Lub hardness ntawm calcium silicon yog 3.5 ~ 4 thiab cov kev nqus tshwj xeeb yog 2.6 ~ 2.8.

Calcium silicon thiab nws cov alloys tau siv dav hauv kev tsim kho, metallurgy, thiab cov calcium silicture tau thiab kev tsim hluav taws xob ua haujlwm thiab hluav taws xob tsis zoo thiab tsis tsim nyog ntawm cov pob zeb. Calcium silicon kuj tseem siv tau los npaj cov ntaub ntawv tshiab hauv tsev xws li calcium silicate laug cam. Cov ntaub ntawv no muaj qhov zoo ntawm lub teeb yuag, muaj zog, hluav taws kub ua haujlwm, thiab yog siv dav hauv kev kho kom zoo nkauj thiab txuag hluav taws xob. Calcium silicon alloy yog ib qho khoom tseem ceeb hauv kev lag luam metallurgical. Nws yog tsuas yog siv raws li inoculant rau cam khwb cia hlau, uas tuaj yeem txhim kho cov qauv thiab cov khoom ntawm cov hlau cam khwb cia. Nyob rau tib lub sijhawm, calcium silicon alloy muaj kev txo peev xwm thiab kuj tau siv los ua deoxidizer rau kev ua tau zoo thiab ua tau zoo ntawm cov hlau. Tsis tas li ntawd, calcium silicon kuj tseem siv tau los npaj lwm cov mettallurgical cov ntaub ntawv. Daim ntawv thov ntawm calcium silicon hauv cov tshuaj lom neeg kev lag luam yog mas cuam tshuam rau hauv kev npaj ntawm ntau yam silicon tebchaw. Cov khoom lag luam silicon no tau siv dav hauv ntau cov khoom siv tshuaj lom xws li roj hmab, plastics, cov nplaum, thiab lwm yam khoom siv rau kev txhim kho cov khoom lag luam thiab txo tus nqi.

Cov txheej txheem ntau lawm ntawm cov calcium silicate feem ntau yog cov kauj ruam hauv qab no: Ua ntej, lim lub lim nta yog calcined kom tau nrawm. Kev xam pom qhov tseeb feem ntau yog nruab nrab ntawm 900 thiab 1000 degrees Celsius, thiab lub sijhawm yog li 1 txog 2 teev. Nyob rau tib lub sijhawm, siliabous raw cov ntaub ntawv xws li Quartz tau npaj. Tom qab ntawd cov calcined illmaslime tau sib xyaw nrog quartz hauv qee qhov kev faib ua feem, thiab qhov sib xyaw kom haum los ntawm stirring thiab reacting nyob rau hauv ib qho tshuaj tiv thaiv tank. Thaum lub sij hawm cov tshuaj tiv thaiv, cov tshuaj calcium nyob rau hauv lub quickTlimime reacts nrog silicon kom tsim kom muaj calcium silicate, thaum tso ntau npaum li cas ntawm tshav kub. Lub sijhawm tshuaj tiv thaiv feem ntau yog los ntawm kaum ob feeb txog ob peb teev. Thaum kawg, cov kev daws tom qab cov tshuaj tiv thaiv tau meej, precipitated thiab lim kom tshem tawm impurities nyob rau hauv kev daws teeb meem thiab txhim kho lub purity ntawm cov khoom. Tom qab ntawd, cov tau calcium sillicate yog qhuav thiab ntim rau kev thauj mus los tom qab thiab siv.
