Putty hmoov yog ib hom khoom siv kho kom zoo nkauj hauv tsev, cov khoom tseem ceeb yog talcum hmoov thiab kua nplaum.Putty yog siv los kho cov phab ntsa ntawm lub substrate rau cov kauj ruam tom ntej los nteg lub hauv paus zoo rau kev kho kom zoo nkauj.Putty muab faib ua ob hom phab ntsa sab hauv thiab sab nrauv phab ntsa, sab nrauv phab ntsa putty tiv taus cua thiab hnub ci yog li kua nplaum, siab zog.Sab hauv phab ntsa putty composite Performance index yog qhov zoo, noj qab nyob zoo, yog li cov phab ntsa sab hauv tsis yog sab nraud, sab nrauv phab ntsa tsis yog sab hauv.Feem ntau cov putty yog gypsum los yog cement-raws li, yog li ntawd lub roughness saum npoo yog yooj yim dua rau lo khov kho.Tab sis nyob rau hauv kev tsim kho los yog pleev xim rau ib txheej ntawm tus neeg saib xyuas interface nyob rau hauv lub hauv paus los kaw lub hauv paus nyob rau tib lub sij hawm lub adhesion ntawm phab ntsa, thiaj li hais tias putty yuav tsum tau bonded rau lub hauv paus.Nws yog ib qho teeb meem tshwm sim tom qab kev tsim kho ntawm putty tias cov hmoov putty yog de-dusted thiab cov hmoov thiab cov dawb huv yog ploj, thiab tom qab ntawd ua ke nrog kev tsim cov putty dryness ntawm phab ntsa, dej nqus, kub, huab cua qhuav thiab lwm yam. .
Ua rau desusting vim li cas ib qho: lub zog sib txuas ntawm putty tsis txaus ua rau desusting, lub zog sib txuas ntawm roj hmab hmoov tsis zoo, qhov sib ntxiv yog me me, tshwj xeeb tshaj yog cov phab ntsa hauv putty, qhov loj ntawm lub zog sib txuas, muaj qhov zoo. kev sib raug zoo ntawm qhov zoo thiab qhov sib ntxiv ntawm cov hmoov thiab kua nplaum.Qhov thib ob yog vim li cas tus qauv tsim tsis tsim nyog.Qhov teeb meem ntawm kev xaiv cov khoom siv thiab cov qauv tseem ceeb heev hauv cov qauv ntawm putty.Piv txwv li, hypromelloseHPMCua tsis-waterproof putty rau sab hauv phab ntsa.Hypromellose HPMC yog kim, tab sis nws tsis ua hauj lwm rau cov fillers xws li shuangfei hmoov, talcum hmoov, wollastonite hmoov, thiab lwm yam, yog hais tias tsuas yog cov hypromellose.HPMCtuaj yeem ua rau carboxymethyl cellulose, thiab tus nqi qis CMC tsis tshem tawm cov hmoov, tab sis carboxymethyl cellulose CMC tsis tuaj yeem ua cov dej tsis muaj dej, thiab tsis tuaj yeem ua rau cov phab ntsa sab nraud, vim tias cov carboxymethyl cellulose CMC ntsib cov txiv qaub-calcium hmoov, cov cement dawb. cov tshuaj tiv thaiv, qhov no yuav ua rau de-hmoov, tab sis kuj ntxiv ntawm Polyacrylamide txiv qaub-calcium hmoov, cov cement dawb ua cov txheej tsis muaj dej, kuj tuaj yeem ua rau cov tshuaj tiv thaiv de-powder.Qhov thib peb ua rau dedusting: qhov sib tov tsis sib xws yog lub ntsiab ua rau desusting ntawm putty rau sab hauv thiab sab nrauv phab ntsa.Qee cov tuam txhab lag luam thoob plaws tebchaws muaj cov cuab yeej siv yooj yim thiab ntau yam los tsim cov hmoov putty, uas tsis yog cov khoom sib xyaw tshwj xeeb, thiab cov khoom sib xyaw tsis sib xws, ua rau cov hmoov putty tawm.
Ua rau dedusting vim li cas plaub: cov txheej txheem ntau lawm yuam kev ua rau putty desusting, yog hais tias tus tov khoom tsis muaj kev ua hauj lwm ntawm tu, residue, zoo tib yam putty nyob rau hauv lub CMC thiab waterproof putty yuav hnov mob nrog grey calcium hmoov, CMC ntawm lub puab phab ntsa putty reacts nrog. cov cement dawb ntawm cov phab ntsa sab nrauv putty ua desusting.Qee lub tuam txhab tau teeb tsa cov cuab yeej tshwj xeeb ntxuav lub qhov ncauj, tuaj yeem ntxuav cov khoom seem hauv lub tshuab, tsis yog tsuas yog ua kom cov putty zoo, tab sis kuj tuaj yeem siv lub tshuab, yuav ib lub cuab yeej los tsim ntau yam putty.Ua rau dedusting tsib yog vim li cas: qhov zoo ntawm fillers kuj yog ib qho yooj yim mus ua desusting, sab hauv thiab sab nrauv phab ntsa putty ib tug loj tus naj npawb ntawm kev siv ntawm fillers, tab sis nyob ib ncig ntawm lub hnyav calcium hmoov, talc nyob rau hauv lub CA2CO3 cov ntsiab lus yog txawv, txawv ph kuj yuav ua rau putty. de-dusting, piv txwv li, Chongqing thiab Chengdu lub sab hauv phab ntsa putty hmoov siv tib cov kua nplaum hmoov, tab sis talc hmoov, hnyav calcium hmoov yog txawv, nyob rau hauv Chongqing tsis de-dusting, nyob rau hauv Chengdu de-dusting, nyob rau hauv Henan, sab qaum teb sab hnub tuaj. tsis txhob tshem cov hmoov, tab sis nyob rau qee qhov chaw kom tshem tawm cov hmoov.Ua rau dedusting laj thawj rau: Huab cua kuj yog ib qho laj thawj rau sab hauv thiab sab nrauv phab ntsa putty dedusting, piv txwv li, sab hauv thiab sab nrauv phab ntsa putty, nyob rau hauv qhuav huab cua ntawm tej thaj chaw nyob rau hauv sab qaum teb, zoo cua, putty finishing zaj duab xis sai sai, tsis dedusting, thiab tsis nyob rau sab qab teb, tshwj xeeb tshaj yog nyob rau hauv ib co cheeb tsam ntawm South Meiyu huab cua, mus sij hawm ntev ntub dej, putty zaj duab xis yog tsis zoo, tab sis kuj off-hmoov, yog li ntawd tej qhov chaw yuav hloov mus rau ntxiv grey calcium hmoov waterproof putty.Ua rau dedusting xya: Grey calcium hmoov, dawb cement thiab lwm yam inorganic binders tsis ntshiab, tov nrog ib tug loj tus naj npawb ntawm yoov-los-hmo ntuj hmoov.Nyob rau hauv kev ua lag luam thiaj li hu ua multi-functional tshauv calcium hmoov, multi-functional dawb cement tsis ntshiab, vim hais tias siv cov impurity inorganic binders, sab hauv thiab sab nrauv phab ntsa waterproof putty yeej tsis waterproof.Ua rau desusting yog vim li cas yim: lub caij ntuj sov sab nrauv phab ntsa putty dej tuav tsis txaus, tshwj xeeb tshaj yog nyob rau hauv high-temperature ventilation lub tsev high-rise qhov rooj, qhov rais thiab lwm qhov chaw, txiv qaub-calcium hmoov thiab cement tsis muaj sij hawm txaus rau thawj txheej dej, thiab tsis tswj kom zoo, nws kuj tuaj yeem ua rau degraded loj heev.
