Kev tso ntawm tus neeg tsim khoom Kaolin: tuaj yeem hloov kho cov cua sov thiab tsis muaj lej, lub thawj yeeb nkab uas siv nyiaj ntau qhov chaw.

Kev Tso Khoom Kaolin Los ntawm Chaw Tsim Khoom: yog tuaj yeem tso koj li cas xeeb thiab tsis muaj cuag, khoom loj ntawm ntau qhov chaw ua haujlwm

Kaolin, ib qhov khoob uas tsis yog neeg ua los ntawm lub tsev kaw, muaj feem ntau thiab siv ntau yam, muaj cheeb tsam los ntawm Xyuj Teb thiab tau nqes mus rau ntau qhov chaw nyob ntawm lub ntiaj teb.

Qhov kev sau no yuav xav pab pom zoo tag nrho txog kaolin, nrhiav xyuas nws qhov chaw los, cov khoom siv hluav taws xob, yam ntxwv phem, qhia nws hom thiab kev siv ntau yam.

Qhov Chaw Los Thiab Lub Sijhawm Ntawm Lub Zejzoo

Kaolin tau txhawb tshwm nyob rau Jingdezhen, Jiangxi Pov, Tsev Ntuj, ib qhov chaw muaj danh pov. Lub npe ntawm kho lus no los ntawm "Gao Ling," lub tzeeg uas nws tau pom ua ntej. Nyob rau xyoo 18, lub nejxlaab tais French d'Entrecolles tau pom daim ntaj no nyob rau lub tzeeg Gao Ling thiab ntxig tsoom mus rau France, pab ntxig rau leej twg uas tsis paub nws zoo li "kaolin." Tam sim no, kaolin tau muaj nuj nqis rau hauv cheeb kam thiab siv tau ntau yam.

Kev Sib Pauv Kim Ho Thaum Thiab Thaum Siv

Kaolin feem ntau muaj kaolinite, yog ib qhov khoob uas sib cuag rau phyllosilicate. Lub ntsiab lus keem ntawm nws feem ntau muaj silicon dioxide (SiO₂), aluminum oxide (Al₂O₃), iron oxide (Fe₂O₃), thiab titanium dioxide (TiO₂). Kaolin meej kub npaum li cas yuav muaj liab thiab muaj feem ntau ntawm powder me me. Lub khoob no tuaj yeem tshwm sim raws li cov thawj ntawv sov lossis cov ntawv sov ruaj khov, muaj kev tso cai zoo, kev nyiaj txiag, kev tiv thaiv xwm fab, thiab kev tiv thaiv tshav kub. Cov yam ntxwv no ua rau kaolin tsim nyog rau ntau yam kev siv, los ntawm ceramics pheej zeb mus rau cov khoom siv tshiab tshaj tawm.

Qhia hom thiab kev tsim

Kaolin tuaj yeem qhia tau tias ib qho tseem ceeb txaug hli ntawm kev tsim thiab yam ntxwv: calcined kaolin, washed kaolin, thiab metakaolin. Ib qho tseem ceeb txaug hli txhua qhov muaj kev processing sib txawv, tshwm sim yam ntxwv thiab kev siv sib txawv.

Washed Kaolin

Kaolin xaum tau tsim los ntawm kev tshem tsov tej ntxaij uas tsis zoo nyob rau hauv kaolinite txwv tsis pub thiab los ntawm kev xaum. Txoj kev no pab tso caij dej nkhaus rau hauv crystal structure ntawm kaolinite, tiam sis tsim tau ib qhov khoom siv muaj kev plasticity thiab cohesiveness zoo.

Txawm tias nws li cas li cas tuaj yeem me me tsawg dua li lwm yam, kaolin xaum muaj kev dispersibility zoo, ua rau nws yog ib qhov zoo tshaj rau siv hauv ceramics, kev tsim duv thiab coating industries.

Nws tus poj ntaub ntawm kev tsim kev sib sau nrog lwm yam khoom pab txhim kho lub zog thiab kev nyob dav ntawm cov khoom tiav.

Calcined Kaolin

Kaolin calcined tau los ntawm kaolin xaum los ntawm kev calcination nyob rau hauv teb nthuav pa thiab siab. Txoj kev no pab hloov pauv cov hom ntawm tej khoom siv, tsim tau ib qho chaw ruaj ruaj thiab looj hnau.

Txhawm rau sawv dhau kaolin xaum, kaolin calcined muaj li cas li cas thiab hardness zoo dua, nyob cuag nrog kev pab kom meej meej.

Txawm li cas los, qhov tshua tshuaj ntawm cov khoom siv yuam tsis pom tau thaum ua qab nyob rau hauv qhov chaw ntxuav. Kaolin tau txuas ntxiv siv rau hauv kev tsim daim duab, kho, roj hmab, kev saib xyuas, thiab cheeb tsam ntau yam uas muaj qhov zoo dua.

Metakaolin

Metakaolin tsim los ntawm kev ntxuav kaolin nyob rau hauv teb nthuav kub tsood, feem ntau nyob ib puag ncig ntawm 600-900°C. Qhov kev tsim no puv siab dhau tus cwj mem tseem ceeb ntawm kaolinite thiab tsim tso cov aluminum silicate uas tsis muaj rau tiam thiab muaj kev cuam tshais ntau.

Txawv npaug ntawm kaolin tau ntxuav, metakaolin tsis txuas ntxiv nrog kev sintering ntau, txwv kom muaj qhov nruab nray ntau. Qhov no ua rau metakaolin zoo los siv rau hauv kev tsim tsev, geopolymers, thiab cov khoom siv los nres tiv. Qhov kev cuam tshais ntau ntawm nws ua rau nws sib cuam thiab nrog lwm yam khoom siv, txhim kho qhov txheej txheem ntawm cov khoom tiag tiag.

Daim ntawv thov thoob plaws kev lag luam

Nyiaj hla tshaj tseem ceeb ntawm kaolin yog ua rau nws tsis tuaj yuam sij nyob hauv ntau qhov chaw lag luam. Nyob hauv qhov chaw lag luam uas tsim cov phuab, kaolin txhawj xeej ua raw material siv los tsim porcelain, stoneware, thiab earthenware. Qhov plasticity thiab cohesiveness ntawm nws pab tswj xyuas kom muaj rau keeb kwm thiab daim duab tseem ceeb, thaum li cas los xwb qhov tso zis tawm ntawm nws txo nqis kev nyiam xeeb ntawm cov khoom tiav. Nyob hauv kev tsim daim ntawv, kaolin ua haujlwm zoo li ib qhov chaw nres thiab chaw sau, pab txo nqis qhov looj, qhov smoothness, thiab qhov yooj yim ntawm kev sau ntawv. Kev siv kaolin nyob hauv cov chaw nres pab txo nqis qhov opaque, qhov gloss, thiab qhov nyiam xeeb ntawm cov chaw nres, ua rau lawv raug siv tau rau ob qhov chaw nres hauv thiab hauv qab.

Nyob hauv qhov chaw tsim kho rau tshuab, kaolin ua zauv ib qhov khoom siv los txhim kho tshuab, pab txhim kho cov nyhuv tshaj plaws ntawm tshuab tshuab xws li kheub, kab ntsug, thiab seals. Nws tus cwj pwm los pab txhim kho qhov ceev thiab kev txaus siab tshaj plaws ntawm tshuab yog li nws yog ib qhov khoom zoo siv. Hauv kev siv khoom siv hlwb, kaolin siv los ua ib qhov khoom pab ntxuav thiab nrhiav nyiaj hauv cov khoom xws li foundations, powders, thiab facial masks. Nws lub neej sov tseg thiab tus cwj pwm los nrhiav nyiaj tshaj plaws yog pab ntau rau pem teb uas muaj peev xwm tshaj plaws.

Ntawd tseem, kaolin muaj feem ntau hauv kev siv tshwj xeeb. Nws cov nyhuv tshaj plaws los nrhiav nyiaj tau zoo tig rau kev tshem tshaiv neeg tshaiv dej thiab av. Cov khoom siv kaolin tau siv hauv kev tshem tshaiv dej tuaj kom zoo los tshem tshaiv cov dej ntoo, dyes, thiab lwm yam khoom tshaiv. Hauv cheeb tsam noj mov, kaolin pab tso kom zoo tagnrho dej noj mov thiab kom tsawg dua qhov kev tshaiv tshaiv.

Cov Tswv Yim Txwv Txwm Thiab Nyob Tag Lub Ntiaj Teb

Nyob rau Hebei Hezhen Industrial Co., Ltd., peb siv nyiaj lo lis tsheb ntxig los tsim kho tshuaj tshaj tseem ceeb uas muaj txuj ci ntawm kev tsim kho cov khoom ua los ntawm kaolin, uas raug tsim los rau kev tswaj tseem ntawm cov neeg siv khoom hauv plhaus ntuj. Peb lub ce siab tias yuav pab kom txhua chav tsim kho kaolin tau txais qhov tseem ceeb tshaj hauv txoj kev tsim kho thiab kev sau nrog. Peb muab cov kev daws teeb meem sib txawv, kev hloov pauv qhov siab npaum li cas thiab qhov caij noj jum ntawm kaolin rau kev siv tshwj tsis. Puas yog cov neeg siv khoom xav tau kaolin rau kev tsim kho hauv cheeb tsam tshaib lossis kev tsim kho tshiab tshaj, peb muab khoom tsoom pub tias yuav tsoom tau.

Xaus

Kaolin, ib qho khoob mineral tsis yog kim tuam, tau dhau los ua ib qhov tseem ceeb hauv ntau cheeb tsam.

Qhov chaw ntawm nws nyob hauv Xybias thiab tom qab los siv hauv txhua qhov chaw ntawm lub ntiaj teb tso nws qhov kev nyob zoo thiab tseem ceeb. Qhov sau nrog kaolin rau hauv cov ntaub ntawv sau, calcined, thiab metakaolin txoj hauv keeb koom nrog rau kev siv tshwj xeeb hauv txhua qhov chaw. Los ntawm cov ntaub ntawv tsuag thiab kev tsim duv mus rau cov khoom siv tshiab thiab kev saib xyuas dej thiab daim ntawv, kaolin tseem tab tom cuam tshuam rau kev tshiab thiab kev ua haujlwm zoo dua. Thaum kev xaum thiab kev tshawb fawb ntev, cov kev siv kaolin yuav tseem nce ntau dua, thim siab nws tus kheej tias yog ib qhov khoom tseem ceeb hauv kev lag luaj.

Nws qhov kev pab kom khoom zoo dua, pab kom ua haujlwm sai dua, thiab pab tiv thaiv dej thiab daim ntawv yog ib qhov tseem ceeb rau kev nrhiav lub neej zoo dua.
