1. Cellulose ethercov khoom siv hauv cov nplaum pobzeb
Ua ib yam khoom siv kho kom zoo nkauj, cov vuas ceramic tau siv dav thoob plaws ntiaj teb, thiab yuav ua li cas muab cov khoom siv ruaj khov no los ua kom nws muaj kev nyab xeeb thiab ruaj khov yeej ib txwm yog qhov txhawj xeeb ntawm tib neeg. Kev tshwm sim ntawm cov nplaum vuas ceramic, hauv Ib qho twg, qhov kev ntseeg siab ntawm cov nplaum vuas yog lav.
Cov cwj pwm tsim kho sib txawv thiab cov txheej txheem tsim kho muaj cov kev cai ua haujlwm sib txawv rau cov nplaum pobzeb. Hauv kev tsim kho pobzeb hauv tsev tam sim no, txoj kev nplaum tuab (cov nplaum nplaum ib txwm muaj) tseem yog txoj kev tsim kho tseem ceeb. Thaum siv txoj kev no, cov kev cai rau cov nplaum pobzeb: yooj yim rau do; yooj yim rau kev thov kua nplaum, riam tsis lo; viscosity zoo dua; zoo dua tiv thaiv kev plam.
Nrog rau kev txhim kho cov thev naus laus zis nplaum rau pobzeb thiab kev txhim kho cov thev naus laus zis tsim kho, txoj kev trowel (txheej txheem nplaum nyias) kuj maj mam siv. Siv txoj kev tsim kho no, cov kev cai rau cov nplaum pobzeb: yooj yim rau do; Riam nplaum; kev ua tau zoo dua los tiv thaiv kev plam; kev ntub dej zoo dua rau cov pobzeb, lub sijhawm qhib ntev dua.
Feem ntau, kev xaiv ntau hom cellulose ether tuaj yeem ua rau cov nplais nplaum ua tiav qhov ua haujlwm tau zoo thiab kev tsim kho.
2. Cellulose ether siv rau hauv putty
Hauv qhov kev xav zoo nkauj ntawm cov neeg sab hnub tuaj, qhov chaw du thiab tiaj tus ntawm lub tsev feem ntau suav hais tias yog qhov zoo nkauj tshaj plaws. Yog li ntawd, kev siv putty tau tshwm sim. Putty yog cov khoom siv plastering nyias nyias uas ua lub luag haujlwm tseem ceeb hauv kev kho kom zoo nkauj thiab kev ua haujlwm ntawm cov tsev.
Peb txheej ntawm cov txheej kho kom zoo nkauj: phab ntsa hauv paus, txheej putty leveling, thiab txheej tiav muaj cov haujlwm tseem ceeb sib txawv, thiab lawv cov modulus elastic thiab deformation coefficient kuj sib txawv. Thaum qhov kub thiab txias, av noo, thiab lwm yam hloov pauv, qhov deformation ntawm peb txheej ntawm cov ntaub ntawv Tus nqi ntawm putty kuj sib txawv, uas xav tau cov ntaub ntawv putty thiab txheej tiav kom muaj cov modulus elastic tsim nyog, cia siab rau lawv tus kheej elasticity thiab yooj ywm kom tshem tawm kev ntxhov siab concentrated, yog li tiv thaiv kev tawg ntawm txheej hauv paus thiab tiv thaiv kev tev tawm ntawm txheej tiav.
Ib qho putty uas muaj kev ua tau zoo yuav tsum muaj kev ua tau zoo ntawm cov substrate ntub dej, rov ua dua tshiab, kev ua haujlwm du, lub sijhawm ua haujlwm txaus thiab lwm yam kev ua haujlwm tsim kho, thiab yuav tsum muaj kev ua tau zoo heev ntawm kev sib txuas, kev ywj pheej, thiab kev ruaj khov. Kev sib tsoo thiab kev ruaj khov thiab lwm yam.
3. Cellulose ether siv rau hauv cov mortar ib txwm
Raws li qhov tseem ceeb tshaj plaws ntawm Tuam Tshoj txoj kev lag luam ntawm cov ntaub ntawv tsim kho, Tuam Tshoj txoj kev lag luam mortar npaj txhij tau maj mam hloov pauv los ntawm lub sijhawm qhia txog kev ua lag luam mus rau lub sijhawm loj hlob sai raws li ob qho kev cuam tshuam ntawm kev txhawb nqa kev ua lag luam thiab kev cuam tshuam txoj cai.
Kev siv cov mortar sib xyaw ua ke yog ib txoj hauv kev zoo los txhim kho qhov zoo ntawm qhov project thiab qib kev tsim kho kom zoo; kev txhawb nqa thiab kev siv cov mortar sib xyaw ua ke yog qhov zoo rau kev siv cov peev txheej dav dav, thiab yog ib qho tseem ceeb rau kev txhim kho kom ruaj khov thiab kev txhim kho kev lag luam ncig; kev siv cov mortar sib xyaw ua ke tuaj yeem txo qhov kev ua haujlwm rov ua dua ntawm kev tsim kho tsev, txhim kho qib kev siv tshuab hauv kev tsim kho, txhim kho kev ua haujlwm zoo, txo kev siv zog ua haujlwm, thiab txo tag nrho cov kev siv zog ntawm cov tsev thaum txhim kho qhov xis nyob ntawm ib puag ncig.
Hauv cov txheej txheem ntawm kev lag luam ntawm cov mortar sib xyaw ua ke, cellulose ether ua lub luag haujlwm tseem ceeb.
Kev siv cellulose ether kom zoo ua rau nws muaj peev xwm siv tshuab los tsim cov mortar uas twb sib xyaw lawm; cellulose ether nrog kev ua tau zoo tuaj yeem txhim kho kev ua tau zoo ntawm kev tsim kho, kev nqus thiab kev txau ntawm mortar; nws lub peev xwm ua kom tuab tuaj yeem txhim kho qhov cuam tshuam ntawm mortar ntub rau ntawm phab ntsa hauv qab. Nws tuaj yeem txhim kho lub zog sib txuas ntawm mortar; nws tuaj yeem kho lub sijhawm qhib ntawm mortar; nws lub peev xwm khaws dej tsis muaj qhov sib piv tuaj yeem txo qhov tshwm sim ntawm cov yas tawg ntawm mortar; nws tuaj yeem ua rau cov dej ntawm cov cement tiav dua, yog li txhim kho lub zog ntawm cov qauv.
Piv txwv li, siv cov tshuaj pleev plastering mortar, ua cov tshuaj pleev zoo, cov tshuaj pleev yuav tsum muaj kev ua tau zoo hauv kev tsim kho: yooj yim do, ntub dej zoo rau phab ntsa hauv qab, du thiab tsis lo rau riam, thiab siv sijhawm ua haujlwm txaus (Tsis tshua poob qhov sib xws), yooj yim rau theem; cov tshuaj pleev hardened yuav tsum muaj lub zog zoo heev thiab qhov zoo li ntawm qhov chaw: lub zog compressive tsim nyog, lub zog sib txuas nrog phab ntsa hauv qab, ruaj khov zoo, qhov chaw du, tsis muaj hollowing, tsis tawg, Tsis txhob poob hmoov.
4. Cellulose ether siv rau hauv caulk/decorative mortar
Ua ib feem tseem ceeb ntawm qhov project tso pobzeb, tus neeg sawv cev caulking tsis yog tsuas yog txhim kho qhov cuam tshuam tag nrho thiab qhov sib piv ntawm qhov project pobzeb, tab sis kuj ua lub luag haujlwm tseem ceeb hauv kev txhim kho qhov tsis muaj dej thiab tsis nkag ntawm phab ntsa.
Ib yam khoom nplaum zoo rau pobzeb, ntxiv rau cov xim nplua nuj, sib xws thiab tsis muaj qhov sib txawv ntawm xim, kuj yuav tsum muaj cov haujlwm ntawm kev ua haujlwm yooj yim, lub zog ceev, qis shrinkage, qis porosity, tsis muaj dej thiab tsis permient. Cellulose ether tuaj yeem txo qhov ntub shrinkage thaum muab kev ua haujlwm zoo heev rau cov khoom sib koom ua ke, thiab qhov ntau ntawm huab cua-entraining yog me me, thiab cov nyhuv rau cement hydration yog me me.
Cov tshuaj pleev kom zoo nkauj yog ib hom khoom siv kho kom zoo nkauj phab ntsa tshiab uas muaj kev sib xyaw ua ke ntawm kev kho kom zoo nkauj thiab kev tiv thaiv. Piv nrog cov khoom siv kho kom zoo nkauj phab ntsa ib txwm muaj xws li pob zeb ntuj, vuas ceramic, xim thiab phab ntsa iav, nws muaj cov txiaj ntsig tshwj xeeb.
Piv nrog cov xim pleev: qib siab; lub neej ntev, lub neej ua haujlwm ntawm cov tshuaj pleev kom zoo nkauj yog ntau zaus lossis txawm tias ntau zaus ntawm cov xim pleev, thiab nws muaj lub neej ntev ib yam li cov tsev.
Piv nrog cov vuas ceramic thiab pob zeb ntuj: zoo sib xws kho kom zoo nkauj; lub nra hnyav dua; muaj kev nyab xeeb dua.
Piv nrog iav ntaub thaiv phab ntsa: tsis muaj kev cuam tshuam; muaj kev nyab xeeb dua.
Cov khoom siv mortar kho kom zoo nkauj uas muaj kev ua tau zoo heev yuav tsum muaj: kev ua haujlwm zoo heev; kev sib txuas zoo thiab txhim khu kev qha; kev sib koom ua ke zoo.
5. Cellulose ether siv rau hauv cov mortar self-leveling
Lub luag haujlwm uas cellulose ether yuav tsum ua tiav rau cov mortar self-leveling:
※ Lav qhov fluidity ntawm tus kheej-leveling mortar
※ Txhim kho qhov muaj peev xwm kho tus kheej ntawm cov tshuaj nplaum uas nws tus kheej kho tau
※ Pab kom ua tau ib qho chaw du
※ Txo qhov ntsws thiab txhim kho lub peev xwm ntawm kev nqa khoom
※ Txhim kho qhov kev nplaum thiab kev sib koom ua ke ntawm cov tshuaj mortar uas nws tus kheej sib npaug rau ntawm qhov chaw puag
6. Cellulose ether siv rau hauv gypsum mortar
Hauv cov khoom lag luam gypsum, txawm tias nws yog plaster, caulk, putty, lossis gypsum-based self-leveling, gypsum-based thermal insulation mortar, cellulose ether ua lub luag haujlwm tseem ceeb hauv nws.
Tsim Nyogcellulose etherCov ntau yam tsis rhiab rau alkalinity ntawm gypsum; lawv tuaj yeem nkag mus rau hauv cov khoom gypsum sai sai yam tsis muaj agglomeration; lawv tsis muaj qhov cuam tshuam tsis zoo rau qhov porosity ntawm cov khoom gypsum kho, yog li ua kom muaj kev ua pa ntawm cov khoom gypsum; qeeb qeeb tab sis tsis cuam tshuam rau kev tsim cov gypsum siv lead ua; muab cov khoom ntub dej kom haum rau qhov sib tov kom ntseeg tau tias muaj peev xwm sib txuas ntawm cov khoom siv rau qhov chaw puag ncig; txhim kho kev ua tau zoo ntawm gypsum ntawm cov khoom gypsum, ua rau nws yooj yim kis thiab tsis lo rau cov cuab yeej.
