Cib yog lub pob zeb tsim los ntawm cov av nplaum thiab dej. Cov ntaub ntawv no tsuas yog siv tshwj xeeb rau kev tsim kho ntawm ntau yam khoom. Cib txawv hauv hom, xim thiab lub zog. Rau kev tsim txhua hom, cov thev naus laus zis tshwj xeeb thiab ntau hom av nplaum siv tau.
Cov hom cib
Tag nrho cov av cib muaj qhov siab ntawm cov dej tsis kam, huab cua tsis kam thiab tiv taus. Raws li kev cai, cov ntaub ntawv no tau muab faib ua ob pawg - dawb thiab liab. Qhov tseeb, muaj ntau ntau hom cib. Feem ntau ntawm lawv yog cov ceramic, silicate, hyper-pressed thiab adobe cib.
Lub ntsiab sib txawv ntawm cov thwv cib tsis yog lawv qhov, tab sis nyob hauv lawv qhov muaj pes tsawg leeg. Cov khoom siv hauv tsev yog tsim los ntawm av nplaum los yog kev sib xyaw ntawm cov xuab zeb thiab kua qaub. Hauv thawj kis, liab liab tau txais, thiab hauv ob, dawb bricks.
Cib tsim ntau lawm
Txog rau thaum xyoo pua puv 19, thoov cib raug siv siv tshuab sib txawv. Txhua lub cib yog tsim los ntawm txhais tes thiab tom qab ntawd hlawv rau hauv qhov cub me me. Cov txheej txheem niaj hnub ua av ci muaj peb theem tseem ceeb. Ua ntej, txhua yam ntaub ntawv tsim nyog tau npaj - cov kua qaub yog tsim, xuab zeb thiab av nplaum yog mined. Cov ntaub ntawv tau ua tiav kom zoo thiab sib xyaw rau hauv cov tebchaw tshwj xeeb.
Cov av nplaum yog tsoo nrog siv cov txheej txheem tshwj xeeb, ua rau hmoov txhuam. Nws yuav tsum raug sau tseg tias tsuas yog qee qhov kev tso nyiaj tau siv rau kev rho tawm ntawm cov khoom no. Tsis yog txhua hom av ntawm av nplaum yog qhov tsim nyog rau ua rau cib.
Cov theem ob hauv kev tsim cov cib yog kev tsim cov khoom tsim tsev thiab nws ua ntej ziab. Lub ntsiab tseem ceeb ntawm cov txheej txheem no yog qhov tshwj xeeb ntawm kev tshem tawm huab cua. Cib yog tsim nyob hauv qab kev kub siab. Ua ntej, lub workpiece yog qhov loj loj, thiab tom qab ntawd nws raug txiav rau hauv cov ntawv me me - cov cib uas paub. Cov khoom ua haujlwm qhuav nyob hauv cov chav loj lossis lub tshuab ziab khaub ncaws.
Qhov kawg theem hauv kev tsim cov cib yog tua hluav taws. Txoj kev no yog nqa tawm hauv qhov cub tshwj xeeb hauv qab ntawm qhov kub ntawm qhov kub tshaj 1000 degrees. Nws yuav tsum raug sau tseg tias cov ntaub ntawv yuav tsum tau qhuav rau ob peb hnub ua ntej xa mus rau qhov cub. Yog tias koj ua qhov no ua ntej, tom qab ntawd lub zog ntawm cov khoom yuav txo qis.
Qhov zoo ntawm txhua pawg ntawm cov cib tsim yog sim siv xovxwm. Ntau qhov qauv yog raug rau qhov siab ntawm ntau dua 50 tons. Cov khoom yuav tsum tsis tsuas yog tiv taus xws li lub nra, tab sis kuj tseem nyob yam tsis muaj kev puas tsuaj hauv daim ntawv ntawm cov chips lossis tawg. Nws ntseeg tias theem tseem ceeb tshaj plaws hauv kev tsim cov cib yog tua hluav taws. Lub waterproofness thiab lub zog ntawm cov khoom nyob ntawm txoj kev no.
