1. Cellulose Enther cov khoom siv siv hauv cov nplais nplaum
Raws li cov khoom siv zoo nkauj ua kom zoo nkauj tau siv dav thoob ntiaj teb, thiab yuav ua li cas muab cov khoom siv ua kom zoo nkauj no kom nws muaj kev txhawj xeeb ntawm cov neeg. Qhov tshwm sim ntawm ceramic pobzeb cov nplaum, nyob rau hauv rau ib qho xwm txheej, kev ntseeg tau ntawm cov pobzeb paste yog lav.
Kev siv kev kho sib txawv thiab cov qauv kev tsim kho muaj cov kev tsim kho kom sib txawv cov khoom ua paug. Nyob rau hauv cov vuas tam sim no ua kev tsim kho, cov tuab txhuam cov txheej txheem (cov khoom siv tsoos nplaum ib txwm) tseem yog txoj kev tsim qauv kev tsim kho. Thaum cov qauv no siv, qhov yuav tsum tau rau cov nplais nplaum nplaum: yooj yim mus do; yooj yim mus thov kua nplaum, tsis-tus riam; Zoo dua viscosity; Zoo dua los tiv thaiv plam.
Nrog rau kev txhim kho ntawm cov nplais nplaum thev naus laus zis thiab kev txhim kho ntawm kev tsim kho thev naus laus zis, cov txheej txheem trowel (nyias muab coj los siv. Siv txoj kev tsim qauv no, cov cai rau cov nplaum nplaum: yooj yim mus do; Cov riam nplaum nplaum; zoo dua kev ua yeeb yam plam; Zoo dua Wettability rau cov vuas, lub sijhawm qhib ntev dua.
Feem ntau, xaiv sib txawv ntawm cov cellulose ether tuaj yeem ua rau cov nplais nplaum ua tiav qhov ua haujlwm sib xws ua tiav thiab kev tsim kho.
2. Cellulose ether siv nyob rau hauv putty
Hauv kev pom zoo ntawm cov ntsiab lus ntawm cov tim khawv, du thiab tiaj tiaj ntawm lub tsev yog feem ntau suav tias yog qhov zoo nkauj tshaj plaws. Daim ntawv thov putty li los ua. Putty yog cov khoom siv plaster sib xyaw uas ua lub luag haujlwm tseem ceeb hauv kev kho kom zoo nkauj thiab ua haujlwm ntawm cov tuam tsev.
Qhov peb txheej ntawm kev ua kom zoo nkauj txheej: puag txog phab ntsa, pufty leveling, thiab lawv txoj kev sib txawv me me thiab deformation coefficient kuj tseem txawv. Thaum lub ambient kub, av noo, etc. Kev hloov pauv ntawm cov zaub mov kom muaj kev ntxhov siab, kom tsis txhob muaj cov txheej txheem ntawm cov txheej txheem ntawm cov txheej txheem ntawm cov txheej thiab kev sib tw ua kom pom tseeb.
Tus putty nrog kev ua tau zoo yuav tsum muaj kev ua kom zoo plias, thiab lwm yam kev tsim kho, thiab kuj yuav tsum tau ua haujlwm zoo, hloov tau zoo, thiab kav ntev. Kev zomability thiab durability thiab lwm yam.
3. Cellulose ether siv nyob rau hauv colling dog dig
Raws li qhov tseem ceeb tshaj plaws ntawm Tuam Tshoj kev ua lag luam ntawm cov ntaub ntawv tsim tsev, Tuam Tshoj npaj txhij hloov ntawm lub sijhawm kev loj hlob hauv khw thiab kev cuam tshuam kev lag luam.
Kev siv npaj txhij cov tshuaj khib yog txhais tau tias zoo los txhim kho theem kev ua tau zoo thiab qib tsim kho; Kev nce qib thiab cov ntawv thov npaj kom txhij-sib xyaw ua kom muaj kev sib xyaw ua ke, thiab yog qhov tseem ceeb rau kev txhim kho kom ruaj khov thiab kev txhim kho ntawm kev lag luam raws li kev lag luam; Kev siv npaj txhij cov tshuaj khib yuav cuam tshuam ntau dua qhov kev tsim kho tshiab, txo cov kev siv zog ntawm kev tsim kho lub zog thaum lub zog ua kom muaj zog ntawm cov chaw nyob.
Nyob rau hauv cov txheej txheem ntawm kev ua lag luam ntawm npaj-sib nphu cellulose, cellulose ua lub luag haujlwm.
Lub meej mom kev siv ntawm cellulose ether ua kom nws muaj peev xwm los siv lub tsev tsim kev tsim kho ntawm cug-mixeded-mixed. cellulose ether nrog kev ua tau zoo tuaj yeem txhim kho kev tsim kho kev tsim kho, nqus dej ntawm cug; Nws lub peev xwm thickening tuaj yeem txhim kho cov nyhuv ntawm cov tshuaj khib ntub ntawm lub hauv paus phab ntsa. Nws tuaj yeem txhim kho txoj kev sib raug zoo ntawm lub tshuaj khib; Nws tuaj yeem kho lub sijhawm qhib ntawm lub tshuaj khib; nws cov khoom siv tsis sib haum hluav taws xob muaj peev xwm txo qhov tshwm sim ntawm cov kab tsuag yas ntawm cov tshuaj khib; Nws tuaj yeem ua rau cov hydration ntawm cov ntseeg mas ua tiav, yog li kev txhim kho lub zog txheej txheem txheej txheem.
Noj cov tshuaj khib dog ua piv txwv ua ib qho piv txwv, ua haujlwm zoo nkauj, kom yooj yim lub sijhawm, thiab tsis muaj sijhawm zoo (thiab theem me me), rau theem yooj yim; Lub zog chlued yuav tsum muaj cov khoom zoo heev thiab lub zog compressive compressive compressive lub zog, zoo durability, tsis muaj hollowing, tsis muaj kev tawg, tsis txhob poob hmoov.
4. Cellulose ether siv nyob rau hauv caulk / zoo nkauj cug
Raws li ib qho tseem ceeb ntawm lub pobzeb thawj tes hauj lwm, tab sis ua tau lub luag haujlwm ntawm cov hluav taws xob tag nrho hauv kev txhim kho cov dej tsis muaj zog thiab tsis tsim nyog ntawm phab ntsa.
Cov khoom lag luam zoo nkauj nplaum zoo nkauj, ntxiv rau cov xim nplua nuj, hnav khaub ncaws yooj yim, yuav tsum muaj cov kev ua haujlwm yooj yim, tsis muaj xim, dej tsis txaus, dej tsis zoo. Cellulose ether tuaj yeem txo cov dej ntub dej thaum muab cov khoom ua haujlwm zoo heev rau cov khoom siv cua ua ke yog me me.
Hniav cov tshuaj khib yog ib hom tshiab ntawm phab ntsa tiav cov khoom siv uas tau sib txuas kom zoo nkauj thiab kev tiv thaiv. Piv nrog tsoos phab ntsa kho kom zoo nkauj xws li pob zeb ntuj, ceramic pobzeb, xim kab hlau thiab iav kab hlau, nws muaj qhov zoo sib txawv.
Piv nrog cov xim: qib siab; Lub neej ntev, kev pabcuam lub neej ntawm cortarative cug yog ob peb zaug lossis txawm tias kaum ob zaug ntawm cov xim, thiab nws muaj tib lub neej ntev li cov tsev.
Piv nrog cov vuas luaj ceramic thiab pob zeb ntuj: cov nyuab zoo nkauj; Lumble kev siv lub nra; Muaj kev nyab xeeb dua.
Piv nrog iav ntaub thaiv phab ntsa: Tsis muaj kev xav; Muaj kev nyab xeeb dua.
Cov khoom siv kho kom zoo nkauj nrog kev ua tau zoo heev yuav tsum muaj: kev ua haujlwm zoo; Kev sib raug zoo thiab txhim khu kev qha; cohesion zoo.
5. Cellulose ether tau siv nyob rau hauv kev sib txig ntawm tus kheej
Lub luag haujlwm uas cellulose ether yuav tsum ua rau tus kheej cug vorting:
※ lav lub fluidity ntawm tus kheej txoj kev npug
※ Txhim kho txoj kev kho tus kheej kho tus kheej
※ pab ua kom muaj qhov chaw du
Cov Roj Txo Kom Yooj Yim thiab Txhim Kho cov kabmob muaj peev xwm
※ Txhim kho cov nplaum thiab cohesion ntawm tus kheej-leveling colling rau lub hauv paus nto
6. Cellulose ether siv nyob rau hauv gypsum tshuaj
Hauv gypsum-based khoom, seb nws yog nws yog yas, pupsum-based tus kheej cug, cellulose ua lub luag haujlwm tseem ceeb hauv nws.
Tsim nyog cellulose ether ntau yam tsis rhiab rau lub alkalinity ntawm gypsum; Lawv tuaj yeem sai infiltrate hauv gypsum cov khoom tsis muaj agglomeration; Lawv tsis muaj qhov cuam tshuam tsis zoo rau lub porosity ntawm kho gypsum, yog li ntseeg tau cov khoom ua pa ntawm gypsum; Retarding nyhuv tab sis tsis cuam tshuam rau kev tsim ntawm gypsum muaju; Muab cov nplaum uas tsis muaj dej ntub rau cov sib tov los kom ntseeg tau tias muaj peev xwm sib raug zoo ntawm cov khoom rau hauv paus; Kev txhim kho Gypsum zoo tshaj plaws ntawm Gypsum cov khoom lag luam, ua rau nws yooj yim sib kis thiab tsis lo rau cov cuab yeej.
