Hloov kho cov tshuaj ntxiv xws li npaj txhij cov tshuaj sib xyaw ua ke, cov neeg sawv cev ntawm cov dej, uas muaj huab cua ua ke, uas tau ntxiv raws li qhov kev xav tau ntawm txoj kev ua tau zoo ntawm kev npaj-sib xyaw mortars. Lub cev nqaij daim tawv thiab cov kws kho tshuab.
1. Npaj-mixed Cais Ntxiv
Lub anionic surfactant muaj nyob rau hauv lub npaj-mixed discapsulated los ntawm Megas aggrate, thiab ua kom tiav nws kom ua tiav cov qauv dej sib cav thiab nce lub tshuaj khib ntom ntom. Lub zog, txhim kho impermability, tawg tsis kam thiab kav ntev. Cov tshuaj khib sib xyaw nrog npaj cov tshuaj sib xyaw muaj zog muaj zog, cov dej sib zog ua kom muaj zog, tsis muaj kuab lom, muaj kev tsis muaj teeb meem, muaj kev nyab xeeb thaum lub sijhawm ua haujlwm. Nws yog qhov tsim nyog rau kev tsim cov khoom zoo ib yam li qub masonry, plastering, av, thiab waterproof cug aged-mixed-mixed-mixed-mixed-mixed-mixeded. Nws yog siv rau cov masonry thiab kev tsim kho cov av nplaum cib, ceramsite cib, pob zeb ua pob zeb hauv ntau lub tsev. Kev tsim kho sab hauv thiab phab ntsa sab nraud thiab phab ntsa plastering, pem teb thiab ru tsev vam, thiab lwm yam.
2. Cellulose ether
Hauv kev npaj-sib nphu cellulose ether yog ib qho kev ua tau zoo ntawm cov tshuaj khib ntub thiab cuam tshuam rau kev ua haujlwm ntawm cug. Cov kev xaiv tsim nyog ntawm cellulose tsim muaj ntau yam, txawv cov viscetle, sib txawv yuav muaj kev sib txawv ntawm kev txhim kho ntawm kev ua kom qhuav.
Kev tsim cov cellulose ether yog feem ntau yog ua los ntawm ntuj fibers los ntawm alkali dissolution, kev sib tsoo), ntxuav tes), ua kom qhuav thiab lwm yam kev ua. Hauv kev tsim cov ntaub ntawv hauv tsev, tshwj xeeb tshaj yog cov hmoov av, cellulose ua lub luag haujlwm (cug cug Cellulose lub luag haujlwm ua lub luag haujlwm ntawm kev ua haujlwm ntawm dej, thickening, ncua kev txhim kho lub zog, thiab txhim kho kev tsim kho kev ua haujlwm. Cov dej ua kom zoo ua rau muaj kev nthuav dav ua tiav, tuaj yeem txhim kho viscosity ntawm lub zog ntub dej ntawm cug, thiab kho lub sijhawm. Ntxiv cov cellulose ether rau cov tshuab txau muab tshuaj yuav txhim kho cov txau lossis nqus ntawm lub cug. Yog li ntawd, cellulose ether tau raug siv dav ua qhov tseem ceeb ntxiv nyob rau hauv npaj-mixed. Lub cellulose cov neeg muaj cai siv hauv kev npaj-sib tov metyl hydrothethyl cellulose ether thiab methyl hydroxypropal ether. , lawv nyob ntau dua 90% ntawm kev lag luam sib koom.
3. Redispersible looj hmoov
Redispersible looj cov hmoov yog ib tug hmoov nplej thermoplastic cob tau los ntawm kev tshuaj tsuag qhuav thiab ua tiav ntawm polsymer emulsion. Nws yog tsuas yog siv hauv kev tsim kho, tshwj xeeb tshaj yog cov tshuaj pleev ib ce qhuav dej kom ua kom cohesion, cohesion thiab yooj.
Lub luag haujlwm ntawm redispersible looj roj cug: redispersible looj ib tug yeeb yaj kiab tom qab dispersion thiab ua raws li cov nplaum thib ob los txhim kho adhesion; Cov tiv thaiv kev tiv thaiv yog nqus los ntawm cov kab tshuaj khib thiab yuav tsis raug pov tseg los ntawm dej tom qab zaj duab xis tsim lossis ob qho kev faib tawm; Zaj duab xis-tsim polymer resin tau faib thoob plaws lub culture system ua cov khoom siv ntxiv, yog li nce cov cohesion ntawm lub cug.
Redispersible looj xas tau txhim kho kev ua haujlwm zoo, txhim kho cov kev ua haujlwm zoo, nce cov dej sib xyaw, nws tuaj yeem txhim kho lub zog tensile. Lub zog tensile, txhim kho cov khoom siv hluav taws xob, txhim kho cov khoom siv tsis kam, txhim kho cov khoom siv hluav taws xob, txhim kho cov khoom siv dej ua kom zoo heev thiab lwm yam cuam tshuam.
4. Cua-Entraining Tus Neeg Sawv Cev
Huab Cua-Entraining Tus Neeg Sawv Cev, tseem hu ua huab cua-Entraining tus neeg sawv cev, uas tuaj yeem txo cov dej sib xyaw ua ke ntawm cov tshuaj khib nyiab hauv cov tshuaj khib nyiab, ua rau muaj kev sib cais zoo dua thiab txo cov tshuaj txhuam sib xyaw. Los ntshav, cais cov quav ntxiv. Ib qho ntxiv, kev qhia ntawm kev nplua thiab cov pa npuas nruab nrab kuj tseem txhim kho kev tsim kho kev ua haujlwm. Tus nqi ntawm cov huab cua kev qhia nyob ntawm seb hom tshuaj khib thiab cov khoom siv siv.
Txawm hais tias tus nqi ntawm huab cua-Entraining tus neeg sawv cev yog qhov collectively cug, txhim kho qhov tsis zoo-sib xyaw ua ke thiab khov rau ntawm cug , thiab txo cov tshuaj cug, txuag cov ntaub ntawv thiab nce thaj chaw tsim kho, tab sis txuas ntxiv ntawm huab cua ntawm lub tshuaj khib, tshwj xeeb tshaj yog cov cug cort. Kev daws teeb meem los txiav txim siab qhov kev pom zoo.
5. Thaum Ntxov Tus Neeg Sawv Cev Thaum Ntxov
Lub zog thaum ntxov yog ib qho kev ntxiv uas tuaj yeem nrawm nrawm ntawm lub zog ntawm lub tshuaj tua hluav taws xob, feem ntau yog cov organic compounds.
Tus tsuj roj kom npaj txhij cov tshuaj khib yog qhov yuav tsum tau ua hmoov thiab qhuav. Calcium tsim yog qhov feem ntau dav siv nyob rau hauv npaj-mixeded cug. Calcium tsim kho tuaj yeem txhim kho thaum ntxov lub zog ntawm cug, thiab ua kom nrawm ntawm cov dej ua haujlwm ntawm trycium silicate, uas tuaj yeem txo cov dej rau ib qho. Ntxiv mus, cov khoom siv lub cev ntawm calcium tsim yog ruaj khov nyob rau hauv chav tsev kub. Nws tsis yooj yim rau agglomerate thiab yog qhov tsim nyog rau cov ntawv thov hauv cov hmoov huv.
6. Dej Reducer
Dej txo tus neeg saib xyuas yog hais txog cov kev ntxiv uas tuaj yeem txo cov dej sib xyaw hauv qab cov xwm txheej ntawm kev ua kom sib xyaw ntawm lub cug cia zoo ib yam. Dej reducer feem ntau yog surfactant, uas tuaj yeem faib ua dej reducers, retarded high effectived dej reducers thiab cov dej reducers raws li lawv cov haujlwm. Cov.
Cov Reducer siv rau npaj txhij cov tshuaj khib yog qhov yuav tsum tau ua hmoov thiab qhuav. Xws li lub taub dej reducer tuaj yeem yog tusyees tawg rau hauv cov hmoov av qhuav tsis muaj kev txo lub neej kom tiav ntawm lub zog-sib nphu. Tam sim no, daim ntawv thov txo tus neeg sawv cev hauv kev npaj tus kheej, gypsum nws tus kheej, thiab lwm yam ntawm cov dej ntws yog nyob ntawm cov khoom siv raw thiab txawv Tshuaj khib cov khoom. Xaiv.
