Kaolin, tseem hu ua china clay, yog cov pob zeb dawb mos mos aluminosilicate uas tsim los ntawm kev hloov pauv ntawm cov pob zeb feldspar uas muaj ntau. Nws muaj nqis heev rau nws cov yam ntxwv tshwj xeeb: dawb thiab ci ntsa iab, me me, plasticity zoo heev, shrinkage tsawg, tshuaj inertness, dispersion zoo, opacity siab, thiab viscosity ruaj khov. Cov yam ntxwv tshwj xeeb no ua rau kaolin yog cov khoom siv thiab cov khoom siv raw uas tsis tuaj yeem hloov pauv tau hauv ntau yam lag luam.

Kev tsim ntawv tseem yog qhov kev siv ntau tshaj plaws, suav txog li 29% ntawm kev siv thoob ntiaj teb. Kaolin ua rau daim ntawv ci ntsa iab, opacity, smoothness, thiab printability, ua haujlwm ua tus neeg sawv cev tseem ceeb thiab tus neeg sawv cev sau. Ceramics ua raws li ze li ntawm 38% ntawm qhov kev thov; kaolin txhim kho molding, lub zog, thiab dawb hauv porcelain, chav dej, vuas, thiab cov khoom siv ceramics siab heev. Nws kuj tseem siv dav hauv cov xim thiab coatings los txhim kho lub zog zais, tiv taus huab cua, thiab ruaj khov.

Lwm yam kev siv tseem ceeb suav nrog fiberglass, roj hmab, yas, nplaum, refractories, tshuaj pleev ib ce, tshuaj, thiab kev kho dej khib nyiab. Cov qib calcined, ntxuav dej, thiab hloov kho qhov chaw ua tau raws li qhov yuav tsum tau ua ntawm kev lag luam rau kev ua tau zoo thiab kev sib xws.

Kev lag luam kaolin thoob ntiaj teb tab tom nthuav dav zuj zus hauv xyoo 2026. Cov ntaub ntawv lag luam qhia tau tias kev lag luam yuav ncav cuagUSD 4.61 billion hauv xyoo 2026nrog ib tug5.3% CAGRtxog xyoo 2034. Qhov ntim kwv yees tias yuav muaj 49.46 lab tons hauv xyoo 2026, loj hlob ntawm 4.24% CAGR mus rau 60.87 lab tons los ntawm xyoo 2031. Cov tsav tsheb tseem ceeb suav nrog kev nqis peev hauv kev tsim kho vaj tse, kev thov ntawv thiab ntim khoom ntau ntxiv, kev tsim kho av nplaum siab heev, thiab kev hloov mus rau cov ntaub ntawv lag luam uas zoo rau ib puag ncig.

Hauv cheeb tsam, Tebchaws Europe tuav lub lag luam ua tus thawj coj, thaumAsia-Pacificyog thaj chaw loj hlob sai tshaj plaws, coj los ntawm Tuam Tshoj, Is Nrias teb, thiab Sab Qab Teb Asia, tsav los ntawm kev lag luam thiab kev loj hlob hauv nroog. Cov neeg tsim khoom tab tom tsom mus rau cov kaolin uas muaj kev ntshiab siab thiab hloov kho kom ntes tau cov ntu muaj nqis siab.

Ua ib qho mineral uas ruaj khov thiab siv tau ntau yam, kaolin lub zeem muag mus sij hawm ntev tseem muaj zog. Kev txhim kho thev naus laus zis thiab kev siv tshiab hauv kev tsim khoom ntsuab, lub zog tshiab, thiab kev tiv thaiv ib puag ncig yuav txuas ntxiv tsav nws qhov kev thov thoob ntiaj teb thiab tus nqi lag luam.
