Attapulgite av nplaum yog ib hom av nplaum magnesium txhuas silicate uas muaj dej ntau nrog cov qauv siv lead ua fibrous tshwj xeeb, uas feem ntau yog tsim los ntawm attapulgite. Nws yog ib qho tseem ceeb tsis tshua muaj cov khoom siv tsis yog hlau. Vim nws muaj kev nqus zoo, tshem tawm xim, thermal stability, tsis kam ntsev, pulping thiab lwm yam khoom, nws yog siv dav hauv kev khawb av nkos, petrochemical, kev lag luam tub rog, cov ntaub ntawv tsim kho, kev ua ntawv, tshuaj, kev ua liaj ua teb, kev tiv thaiv ib puag ncig thiab ntau lwm yam teb.HCMilling (Guilin Hongcheng)yog ib lub chaw tsim khoom ntawmattapulgitelub tshuab sib tsooNov yog qee cov lus qhia rau kev txhim kho thiab kev siv cov peev txheej attapulgitenyob rau hauv Anhui xeev, Suav teb:

HLMattapulgite sib tsoo zeb

Cov pob zeb loj ntawm thaj chaw khawb av hauv xeev Anhui, Suav teb, tshwm sim hauv Cenozoic Tertiary basalt interlayer. Nws muaj 3 txog 4 txheej ntawm cov hlau, uas tau faib kab rov tav hauv cov txheej. Lub thickness ntawm lub cev hlau yog 1.05 meters txog 15.9 meters. Lub thickness ntawm txheej yog ruaj khov, nrog kev sib txuas zoo. Lub qhov tob faus feem ntau yog 10 txog 94 meters. Qee qhov chaw raug nthuav tawm ntawm qhov chaw. Cov ntsiab lus ntawm attapulgite hauv cov khoom siv hauv cov ntxhia yog 43.2%, txog li 96%, qib siab thiab zoo. Qhov thib ob, quartz, dolomite thiab montmorillonite muaj crystallinity siab thiab cov noob loj; Lub chaw tsim khoom ntawmattapulgite sib tsoo zebkawm tau tias cov chaw tso nyiaj (cov chaw) hauv thaj tsam Longshan ntawm Feidong County yog tsim los ntawm basalt, andesitic fused tuff thiab volcanic agglomerate interlayers,attapulgitemuaj nyob rau hauv thaj tsam tawg, thiabattapulgiteCov ntsiab lus hauv cov khoom xyaw hauv cov pob zeb yog ntau dua 90%. Qhov thib ob yog quartz thiab albite. Qhov loj me ntawm cov pob zeb feem ntau yog nanometer submicron. Attapulgite fibers tau teeb tsa hauv cov pob thiab cov lus qhia, nrog rau qhov du, ncaj nto thiab daim phiaj faib.

Nyob rau hauv xyoo tas los no, Tuam Tshoj tau txhawb nqa kev txhim kho thiab kev siv cov peev txheej av nplaum attapulgite thiab tau tshaj tawm ntau cov phiaj xwm tseem ceeb. Lub chaw tsim khoom ntawmattapulgite sib tsoo zebtau kawm tias nyob rau hauv Kev Npaj Cov Khoom Siv Hauv Av ntawm Anhui Xeev (2016-2020), nws tau npaj siab los txhawb kev ua cov av nplaum attapulgite thiab lwm yam minerals tob, thiab txhawb kev tsim kho thiab kev siv cov khoom siv hmoov zoo heev, cov khoom hloov kho, cov khoom siv tshwj xeeb thiab lwm yam khoom siv hauv av. Hauv kev npaj cov khoom siv hauv av ntawm Mingguang City, Jianxi attapulgite av nplaum tseem ceeb hauv thaj chaw khawb av thiab Guanshan Jianxi attapulgite av nplaum tseem ceeb hauv thaj chaw tsim kho tau raug xaiv, npog thaj tsam ntawm 196.21 square kilometers. Kev cia siab rau lub tiaj ua si attapulgite av nplaum, cov chaw ua haujlwm attapulgite av nplaum uas nyob ib puag ncig tau raug koom ua ke, cov chaw ua haujlwm tseem ceeb rau kev nthuav dav thiab kev hloov pauv tau raug tswj hwm, thiab kev tsim cov khoom siv adsorption zoo, cov ntaub ntawv colloidal, cov ntaub ntawv polymer organic composite thiab lwm yam khoom siv carbon tsawg, kev tiv thaiv ib puag ncig Cov khoom muaj nqis ntxiv.

Cov av nplaum Attapulgite tam sim no feem ntau yog siv rau cov ntaub ntawv adsorption, cov ntaub ntawv ua haujlwm colloidal, cov ntaub ntawv nano ua haujlwm, thiab lwm yam. Kev ntxuav kua thiab kev tshem tawm roj yog cov lag luam loj tshaj plaws rau cov av nplaum attapulgite siv los ua adsorbent. Siv tus nqi 0.8% ~ 6.0%; Tom qab raug sib tsoo los ntawm attapulgite sib tsoo zeb, qhov ntau siv rau hauv txheej yog 0.3% ~ 3.0%. Tsis tas li ntawd, nws kuj tseem siv tau rau ntau qhov chaw ua lag luam xws li desiccant, cov khoom siv lim cua, cov khoom noj khoom haus ntxiv, kev hloov kho cov khoom siv polymer, thiab lwm yam.

Tuam Tshoj txhawb nqa kev txhim kho tag nrho cov saw hlau kev lag luam ntawm attapulgite av nplaum, taw qhia tias cov khoom siv av nplaum attapulgite feem ntau yog siv rau hauv kev lag luam tshuaj lom neeg tshiab (xim ntsuab) thiab kev lag luam khoom siv tshiab. Ntawm lawv, kev lag luam tshuaj lom neeg tshiab yog tsom mus rau kev sib raug zoo ntawm cov khoom tshwj xeeb ntawm colloidal attapulgite av nplaum thiab cov txheej ntsuab, tsim "Lub Nroog ntawm Cov Txheej Txheem Dej hauv Suav Teb" hauv Mingguang City, ua thawj pawg ntawm "Green Coatings Park" hauv Suav Teb, thiab txhua lub tuam txhab loj tau nyob hauv. Lub peev xwm tsim khoom txhua xyoo ntawm cov txheej ntsuab yuav ncav cuag ze li ntawm lab tons. Kev siv cov av nplaum attapulgite hauv cov txheej yuav yog 0.3% ~ 3.0%. Nws tau kwv yees tias qhov kev thov rau attapulgite mineral hmoov yuav ncav cuag ntau pua txhiab tons; Kev lag luam khoom siv tshiab yog los tshawb fawb, tsim kho thiab tsim cov khoom siv tshiab raws li attapulgite xws li attapulgite filler, adsorbent, cov ntaub ntawv tsim kho tshiab, cov hmoov tshiab sau, desiccant, decolorant attapulgite, thiab lwm yam.

Kev tsim kho thiab siv cov peev txheej attapulgite tsis tuaj yeem ua yam tsis muaj kev txhawb nqa ntawmattapulgite sib tsoo zeb cov khoom siv. Lubattapulgitelub tshuab sib tsootsim los ntawmHCMilling (Guilin Hongcheng)tau siv dav thiab lees paub hauv kev lag luam thoob ntiaj teb. Nws tuaj yeem ua tiav 80-2500 mesh attapulgite hmoov, nrog cov qauv khoom tiav thiab cov pawg nplua nuj. Yog tias koj xav tau kev tsim kho thiab siv attapulgite, thov hu rau peb kom paub meej ntxiv.
