I. Keeb Kwm Ntawm Qhov Project: Cov Kev Xav Tau Tseem Ceeb Ntawm Kev Lim Dej Sodium Silicate Uas Kub Heev
Sodium silicate yog ib yam khoom siv tshuaj lom neeg tseem ceeb uas siv dav hauv kev lag luam xws li cov tshuaj ntxuav tes, kev tsim kho, thiab cov ntaub. Tus neeg siv khoom hauv kev koom tes no yog lub tuam txhab tshuaj lom neeg paub zoo hauv Sri Lanka, feem ntau koom nrog kev tsim khoom thiab muag cov khoom sodium silicate series. Nrog rau kev nthuav dav ntawm kev thov ua lag luam, cov khoom siv lim dej qub ntawm tus neeg siv khoom tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev tsim khoom, ntsib ntau yam teeb meem kev siv tshuab.
Qhov kev thov tseem ceeb ntawm tus neeg siv khoom yog qhov tseeb: kom ua tiav kev lim dej ruaj khov ntawm 8 tons ntawm sodium silicate ib hnub, nrog rau qhov kub lim dej tswj hwm ntawm 80 ℃. Sodium silicate muaj cov yam ntxwv ntawm viscosity siab thiab yooj yim crystallization ntawm qhov kub siab, thiab cov slurry thawj muaj cov insoluble silicate impurities xws li hlau, txhuas, calcium, thiab magnesium. Yog tias qhov tseeb ntawm kev lim dej tsis txaus, nws yuav cuam tshuam loj heev rau qhov huv ntawm cov khoom, yog li cuam tshuam rau kev siv cov neeg siv khoom downstream. Tib lub sijhawm, tus neeg siv khoom xav tau tias lub kaw lus lim dej ua haujlwm zoo thiab ruaj khov, tuaj yeem txo tus nqi ntawm kev saib xyuas tes, thiab ua raws li kev tiv thaiv ib puag ncig hauv zos thiab cov qauv kev nyab xeeb ntawm kev tsim khoom.
II. Kev daws teeb meem:Kev lim dej siab tshwj xeeb + lub twj tso kua mis ntsia hlau
Ua raws li qhov xav tau ntawm cov neeg siv khoom rau kev lim dej kub thiab viscosity siab, ua ke nrog cov yam ntxwv ntawm cov khoom siv sodium silicate, peb tau kho kom haum rau kev lim dej sib xyaw nrog lub lim dej siab ua lub hauv paus thiab lub twj tso kua mis tshwj xeeb ua ib qho ntxiv. Txij li kev xaiv cov khoom siv, kev ua kom zoo dua qub mus rau kev sib koom ua ke ntawm lub kaw lus, peb ua kom ntseeg tau tias cov txiaj ntsig lim dej thiab kev ua haujlwm zoo.
1. Kev xaiv cov khoom siv tseem ceeb: Lub lim dej siab uas haum rau cov xwm txheej kub siab
Xav txog qhov kub thiab txias 80 ℃, cov phaj lim polypropylene ib txwm muaj feem yuav deformation. Peb xaiv cov khoom siv lim siab stainless hlau 316L. Cov khoom siv no muaj kev tiv thaiv corrosion zoo thiab kev ua haujlwm kub siab zoo heev, uas tuaj yeem tiv thaiv cov phaj lim deformation thiab teeb meem xau hauv qab qhov kub thiab txias. Tib lub sijhawm, raws li qhov ntim ua tiav txhua hnub 8-tuj, thaj chaw lim tau raug suav kom raug, thiab cov khoom siv lim chav sib xws thiab cov ntaub lim ntaub tau teeb tsa - daim ntaub lim siv cov khoom siv polypropylene tiv taus kub siab, nrog qhov loj me me dua li tus nqi D90 ntawm lub hom phiaj impurities, uas tuaj yeem ntes cov impurities zoo thaum ua kom ntseeg tau tias qhov ntws ntawm kev lim thiab zam qhov tshwm sim "khiav tawm".
Yuav kom txhim kho qhov kev lim dej kom zoo dua, lub tshuab lim siab siv cov thev naus laus zis tswj qhov sib txawv ntawm qhov siab. Thaum qhov sib txawv ntawm qhov siab sab hauv thiab sab nraud ntawm lub tshuab lim dej ntau dua 0.2MPa, lub tshuab yuav kho qhov siab ntawm qhov tawm ntawm cov kua lim kom tswj tau qhov sib txawv ntawm qhov siab kom nyob hauv qhov chaw nyab xeeb, ua kom lub voj voog lim dej ntev dua thiab ua kom lub ntim thiab ceev ntawm kev lim dej ntau dua. Tsis tas li ntawd, cov khoom siv no muaj lub tshuab tswj semi-automatic, uas tuaj yeem ua tiav kev nias, tso tawm, thiab txo qhov siv zog ntawm kev ua haujlwm tes.
2. Kev sib phim ntawm lub tshuab nqa khoom: Lub twj tso kua mis ntsia hlau tshwj xeeb ua kom muaj kev pub mov ruaj khov
Cov sodium silicate slurry muaj viscosity siab thiab muaj cov khoom tsis huv. Cov twj tso kua mis conveying ib txwm muaj feem yuav txhaws thiab hnav. Peb tau muab rau tus neeg siv khoom nrog lub twj tso kua mis ntsia hlau uas tsis yooj yim hnav, uas muaj kev ntws ruaj khov thiab lub zog me me, thiab tuaj yeem ua tau raws li qhov xav tau ntawm cov khoom siv viscosity siab thiab cov khoom muaj cov khoom me me. Qhov ceev ntawm lub twj tso kua mis ntsia hlau tuaj yeem hloov kho los ntawm kev hloov pauv zaus kom phim qhov ceev ntawm lub lim dej siab, zam kev thaiv lub phaj lim vim qhov ceev ntawm kev pub mis lossis cuam tshuam rau kev ua haujlwm ntau lawm vim qhov ceev ntawm kev pub mis tsis txaus. Tib lub sijhawm, lub cev twj tso kua mis thiab cov kav dej conveying tau nruab nrog cov ntaub ntawv ceramic uas tsis yooj yim hnav kom txhim kho kev tiv thaiv kev hnav thiab txuas ntxiv lub neej ua haujlwm ntawm cov khoom siv.
