Cov khoom siv hmoov hlau slag muaj kev cia siab zoo hauv kev lag luam. Tam sim no, qhov muaj CaO dawb thiab MgO hauv cov hlau slag txo nws qhov ntim ruaj khov; Cov ntsiab lus siab ntawm hlau oxide ua rau muaj kev nyuaj sib tsoo, kev siv hluav taws xob ntau rau ib tuj ntawm cov hmoov slag, thiab kev ua cov hmoov hlau slag nyuaj. Yog li ntawd, qhov muag khoom ntawm cov hmoov hlau slag yog me me. Kev siv cov hmoov hlau slag los ntawm cov hlau stainless slag sib tsoo tseem yog kev lag luam tshiab uas yuav tsum tau tsim. Cov hauv qab no piav qhia txog lub hauv paus ntsiab lus thiab thev naus laus zis ntawm kev siv cov hlau stainless slag hauv kev ua ntawv:

Nws yog ib qho tsis zam tsis tau los tsim cov hlau stainless slag hauv cov txheej txheem ntawm cov hlau (stainless hlau). Kev siv cov hlau stainless slag rau kev ua ntawv tsis yog tsuas yog daws qhov teeb meem ntawm kev ua qias tuaj ib puag ncig los ntawm cov hlau slag, tab sis kuj tuaj yeem tsim cov txiaj ntsig kev lag luam siab. Yog li, yuav ua li cas ua ntawv nrog cov hlau slag? Cov kws tshawb fawb Suav Liu Fuxing thiab Liu Zhiyong, tau pom los ntawm ntau qhov kev tshawb fawb thiab kev sim tias cov hlau stainless slag tau dhau los ntawm qhov kub siab thiab nws cov tshuaj lom neeg muaj zog ruaj khov. Cov ntsiab lus ntawm CaO yog siab, thiab cov ntsiab lus tsis zoo yog me me, uas tuaj yeem siv rau kev ua ntawv. Lawv muab cov thev naus laus zis ua ntawv nrog kev siv cov hlau stainless slag tag nrho.

Lub hauv paus ntsiab lus ntawm kev siv cov hlau tsis xeb slag hauv kev siv tshuab ua ntawv yog siv cov hlau tsis xeb slag ua cov khoom siv raw rau kev ua ntawv, thiab siv cov thev naus laus zis hmoov zoo heev ntawm hlau slagntsug roller zebthiab siv tshuab sib cais sib nqus siab heev los kho cov hlau stainless slag, kom cov hlau stainless slag ua hmoov zoo heev nrog qhov loj me ntawm 800 ~ 1000 mesh thiab siv tau rau kev ua ntawv, thiab tom qab ntawd siv cov hmoov zoo heev ua cov khoom siv raw tseem ceeb thiab cov khoom siv polymer los sib tov cov khoom hloov kho, thiab tom qab ntawd nias kom ua daim ntawv hauv paus. Tsis tas li ntawd, daim ntawv tsim los ntawm kev siv tshuab ua ntawv ntawm cov hlau stainless slag yuav tawg ua qe qe tom qab rau lub hlis ntawm kev raug tshav ntuj, thiab lub ntiaj teb yuav rov qab mus rau qhov xwm txheej. Faus hauv av rau ib xyoos, nws tuaj yeem raug rhuav tshem ua hmoov (hmoov av inorganic), yam tsis ua rau muaj kuab paug rau ib puag ncig. Tom qab rov ua dua tshiab, lub thawv tuaj yeem xa rov qab mus rau kab ntau lawm rau kev siv (cov txheej txheem ib txwm yuav tsum tau rov ua dua). Txawm tias nws raug hlawv hauv lub cub tawg, tsuas yog cov khoom siv macromolecular xwb thiaj li raug hlawv. Cov hmoov hlau stainless slag tuaj yeem txhawb kev sib cuag ntawm cov khoom siv macromolecular thiab huab cua kom ua kom tiav kev sib xyaw ua ke. Nws yuav tsis tsim cov pa luam yeeb dub vim yog kev tuag tes tuag taw vim tsis muaj oxygen. Tsis muaj cov pa roj lom tom qab hlawv, thiab cov pa roj carbon dioxide tsawg heev.

Cov hlau stainless slag yog siv dav ua cov khoom siv ua ntawv, suav nrog lub tshuab milling qhuav: suav nrog cov sib cais sib nqus thiabhmoov hlau slagntsug roller zebCov hlau stainless slag raug tshem tawm los ntawm kev sib cais sib nqus thiab tom qab ntawd tsim ua hmoov zoo heev nrog qhov loj me ntawm 800 ~ 1000 mesh los ntawmhmoov hlau slagntsug roller zeb; Lub kaw lus ua ntawv calendering, suav nrog cov khoom siv hloov kho polymer thiab calender; Lub kaw lus npaj hmoov qhuav thiab lub kaw lus ua ntawv calender tau teeb tsa ua ntu zus raws li cov txheej txheem kev coj ua. Lub kaw lus ua ntawv calender, cov hmoov ultrafine yog hloov kho los ntawm cov khoom siv hloov kho polymer thiab tom qab ntawd dhau los ntawm calender los tsim cov ntawv hauv paus. Cov txheej txheem thev naus laus zis ntawm kev siv dav dav thiab kev ua ntawv ntawm cov hlau stainless slag yog raws li nram no: cov hlau stainless slag nrog qhov loj me ntawm 0 ~ 200mm yog crushed rau 0 ~ 15mm tom qab dhau los ntawm lub puab tsaig crusher thib ob, thiab cov khoom me me nrog qhov loj me ntawm 0 ~ 15mm raug tshuaj xyuas los ntawm lub vijtsam vibrating, thiab tom qab ntawd crushed rau 0 ~ 8mm los ntawm lub crusher, thiab tom qab ntawd sib cais sib nqus yog nqa tawm tom qab sib cais sib nqus, thiab cov hlau slag tom qab tshem tawm hlau los ntawm kev sib cais sib nqus yog grinded rau 800-1000 mesh los ntawmhmoov hlau slag zoontsug roller zebCov paraffin ntxiv ua cov khoom siv pabcuam nkag mus rau hauv lub tshuab sib tov, thiab tom qab ntawd nkag mus rau hauv lub calender rau calendering thiab papermaking tom qab raug hloov kho los ntawm cov khoom siv polymer hloov kho.

Qhov nyuaj ntawm kev siv cov hlau stainless slag hauv kev ua ntawv yog nyob rau hauv lub tshuab milling qhuav. Vim tias cov ntsiab lus siab ntawm hlau oxide hauv cov hlau slag, qhov nyuaj sib tsoo yog nce, thiab kev siv hluav taws xob siab ib tuj ntawm cov hmoov slag yog siab, thiab kev ua cov hmoov hlau slag yog qhov nyuaj. Raws li qhov no, lubHLMX steel slagntsug roller zeb Lub kaw lus tsim thiab tsim los ntawm HCMilling (Guilin Hongcheng) muab kev txhawb nqa rau kev siv cov hlau stainless slag rau kev ua ntawv. Siv cov hlau slag hmoov ntsug roller mill los tsim ib tuj ntawm 800-1000 mesh hlau slag hmoov tuaj yeem txuag tau 30% ~ 50% ntawm hluav taws xob dua li siv cov pob zeb ib txwm muaj los tsim tib qhov hnyav ntawm hmoov, thiab cov zis txhua teev tau nce ntau heev, ua tau raws li qhov xav tau ntawm kev siv cov hlau stainless slag hauv kev lag luam ua ntawv. Hlau slag yog milled los ntawmhlau slagntsug roller zebCov ntaub ntawv raug zom rau hauv qhov kub siab (100 ℃ ~ 300 ℃) thiab ib puag ncig noo noo. Feem ntau ntawm cov calcium oxide dawb thiab magnesium oxide dawb hauv cov hmoov hlau slag yog hydrated rau hauv cov calcium hydroxide thiab magnesium hydroxide uas muaj zog heev. Thaum lub sijhawm tsim cov hmoov hlau slag, tsuas yog ib feem ntawm cov roj kub xav tau kom qhuav cov dej hauv cov hlau slag thiab tsis muaj pa luam yeeb. Kev npaj cov hmoov hlau slag los ntawm lub tshuab sib tsoo stainless hlau slag kuj yog ib qho project tiv thaiv ib puag ncig ntsuab. Nws tsis tsuas yog tig cov khib nyiab mus rau hauv cov khoom muaj nqis, txhim kho tus nqi ntxiv ntawm kev ua hlau, tsim cov txiaj ntsig kev lag luam loj rau cov lag luam hlau, tab sis kuj tiv thaiv ib puag ncig. Yog tias koj xav paub txog cov ntawv ua hlau slag micro-hmoov thiab cov hlau slag micro-hmoov ntsug roller mill, thov hu rau HCM rau cov ntsiab lus khoom siv.
