Putty hmoov tawm hmoov teeb meem

De-powdering thiab whitening ntawm sab hauv phab ntsa putty hmoov yog tam sim no feem ntau cov teeb meem tom qab putty tsim.Yuav kom nkag siab txog cov laj thawj rau sab hauv phab ntsa putty hmoov de-powder, ib qho yuav tsum xub nkag siab txog cov khoom siv raw khoom thiab kev kho cov txheej txheem ntawm sab hauv phab ntsa putty hmoov, thiab tom qab ntawd muab sib xyaw ua ke Thaum lub sij hawm siv putty, dryness ntawm phab ntsa nto, dej nqus tus nqi, kub. , dryness ntawm huab cua, thiab lwm yam., nrhiav kom paub lub ntsiab yog vim li cas rau cov hmoov poob ntawm putty hmoov nyob rau hauv lub puab phab ntsa thiab siv cov coj txoj kev los daws qhov teeb meem ntawm hmoov poob ntawm putty hmoov.

Lub hauv paus raw khoom muaj pes tsawg leeg ntawm sab hauv phab ntsa putty hmoov:

Cov khoom xyaw tseem ceeb tshaj plaws ntawm sab hauv phab ntsa putty hmoov muaj xws li: inorganic bonding material (ash calcium), fillers (hnyav calcium hmoov, talcum hmoov, thiab lwm yam) polymer additives (HPMC, polyvinyl cawv, roj hmab hmoov, thiab lwm yam.)

Ntawm lawv, sab hauv phab ntsa putty hmoov feem ntau tsis ntxiv cov cement dawb lossis tsuas yog ntxiv me me ntawm cov cement dawb.Redispersible latex hmoov tsis tshua muaj txiaj ntsig nyob rau hauv cov ntaub ntawv ntawm cov tshuaj tsawg, yog li nws tsis yog siv rau sab hauv phab ntsa putty hmoov feem ntau vim yog tus nqi, lossis nws tsis tshua siv.

Yog li vim yog qhov teeb meem ntawm sab hauv phab ntsa putty hmoov mis nws tus kheej:

1. Inorganic bonding cov ntaub ntawv, xws li ntxiv cov hmoov tshauv calcium tsawg dhau, thiab cov hmoov tshauv calcium tsis zoo li tus qauv;

2. Yog tias tus nqi ntawm cov khoom sib txuas hauv cov khoom siv polymer tsawg dhau los yog qhov zoo tsis yog raws li tus qauv, nws yuav ua rau cov hmoov putty ntawm cov phab ntsa sab hauv poob.

Muab faib ua cov hauv qab no:

01. Lub zog nplaum ntawm lub putty tsis txaus ua rau cov hmoov tshem tawm.Cov chaw tsim khoom blindly txo tus nqi.Lub zog nplaum ntawm cov hmoov roj hmab tsis zoo thiab qhov sib ntxiv yog me me, tshwj xeeb tshaj yog rau cov phab ntsa sab hauv putty.Qhov zoo ntawm cov roj hmab hmoov thiab cov kua nplaum muaj ntau yam ua nrog cov nyiaj ntxiv.

02. Cov qauv tsim tsis tsim nyog, qhov teeb meem ntawm kev xaiv cov khoom siv thiab cov qauv tseem ceeb heev hauv cov qauv putty.Piv txwv li, hydroxypropyl methylcellulose (HPMC) yog siv los ua cov tshuaj tsis muaj dej tsis zoo rau cov phab ntsa sab hauv.Txawm hais tias HPMC yog kim heev, nws tsis ua hauj lwm rau cov fillers xws li ob npaug ya hmoov hmoov, talcum hmoov, wollastonite hmoov, thiab lwm yam. Yog tias tsuas yog siv HPMC, nws yuav ua rau delamination.Txawm li cas los xij, CMC thiab CMS nrog tus nqi qis tsis tshem cov hmoov, tab sis CMC thiab CMS tsis tuaj yeem siv los ua cov dej tsis zoo, tsis tuaj yeem siv los ua cov phab ntsa sab nrauv, vim CMC thiab CMS hnov ​​​​mob nrog grey calcium hmoov thiab cov cement dawb, uas yuav ua rau. delamination.Kuj tseem muaj cov polyacrylamides ntxiv rau cov txiv qaub calcium hmoov thiab cov cement dawb ua cov txheej txheem dej, uas tseem yuav ua rau cov tshuaj lom neeg ua rau cov hmoov tshem tawm.

03. Kev sib xyaw tsis sib xws thiab nplawm yog qhov laj thawj tseem ceeb rau cov hmoov tshem tawm ntawm cov khoom siv ntawm cov phab ntsa sab hauv thiab sab nrauv.Qee cov tuam txhab lag luam hauv lub tebchaws tsim cov hmoov putty nrog cov khoom siv yooj yim thiab ntau yam.Lawv tsis yog cov khoom sib xyaw tshwj xeeb, thiab kev sib xyaw tsis sib xws ua rau cov hmoov tshem tawm.

04. Qhov kev ua yuam kev hauv cov txheej txheem tsim khoom ua rau cov putty yog hmoov.Yog tias qhov sib tov sib xyaw tsis muaj kev ua haujlwm ntawm kev tu thiab muaj cov khoom seem ntxiv, CMC hauv cov khoom siv zoo tib yam yuav hnov ​​​​mob nrog cov hmoov tshauv calcium hauv cov dej tsis muaj dej.CMC, CMS thiab cov cement dawb ntawm sab nrauv phab ntsa putty reacts thiab ua rau de-powder.Qee lub tuam txhab cov cuab yeej tshwj xeeb yog nruab nrog lub chaw nres nkoj tu, uas tuaj yeem ntxuav cov khoom seem hauv lub tshuab, tsis yog tsuas yog ua kom cov putty zoo, tab sis kuj siv ib lub tshuab rau ntau lub hom phiaj, thiab yuav ib qho khoom siv los tsim ntau yam. putty.

05. Qhov zoo ntawm cov fillers kuj yooj yim ua rau de-powder.Ib tug loj tus naj npawb ntawm fillers yog siv nyob rau hauv sab hauv thiab sab nrauv phab ntsa putty, tab sis cov ntsiab lus ntawm Ca2CO3 nyob rau hauv hnyav calcium hmoov thiab talc hmoov nyob rau hauv ntau qhov chaw yog txawv, thiab qhov sib txawv ntawm pH kuj yuav ua rau de-powder ntawm putty, xws li Chongqing thiab Chengdu lub sab hauv phab ntsa putty hmoov siv tib cov roj hmab hmoov, tab sis talcum hmoov thiab hnyav calcium hmoov sib txawv.Nws tsis de-hmoov hauv Chongqing, tab sis nws de-hmoov hauv Chengdu.Nws tsis de-hmoov hauv Henan thiab Northeast Tuam Tshoj, tab sis nws de-hmoov hauv qee thaj chaw.

06. Qhov laj thawj ntawm huab cua kuj yog vim li cas rau cov hmoov tshem tawm ntawm cov putty rau ntawm phab ntsa sab hauv thiab sab nrauv.Piv txwv li, lub putty rau sab hauv thiab sab nrauv phab ntsa muaj huab cua qhuav thiab qhov cua zoo nyob rau qee qhov chaw qhuav nyob rau sab qaum teb.Qee qhov chaw muaj huab cua los nag, cov av noo mus ntev, putty zaj duab xis-tsim cov khoom tsis zoo, thiab nws tseem yuav plam hmoov, yog li qee qhov chaw tsim nyog rau cov dej tsis zoo nrog cov hmoov tshauv calcium hmoov.

07. Inorganic binders xws li grey calcium hmoov thiab cov cement dawb yog impure thiab muaj ntau ntawm Shuangfei hmoov.Lub thiaj li hu ua multi-functional grey calcium hmoov thiab multi-functional dawb cement nyob rau hauv lub lag luam yog impure, vim hais tias ib tug loj npaum li cas ntawm cov impure inorganic binders yog siv, thiab cov waterproof putty ntawm sab hauv thiab sab nrauv phab ntsa yuav twv yuav raug hu tsis muaj hmoov. thiab tsis waterproof.

08. Nyob rau lub caij ntuj sov, cov dej khaws cia ntawm cov putty rau ntawm phab ntsa sab nrauv tsis txaus, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias qhov chaw xws li cov qhov rooj thiab qhov rais siab.Lub sijhawm pib ntawm cov hmoov tshauv calcium hmoov thiab cement tsis txaus, thiab dej yuav ploj.Yog tias nws tsis tau khaws cia zoo, nws kuj tseem yuav ua hmoov hnyav.
