1. Cellulose ethercov khoom siv hauv cov nplais nplaum
Raws li cov khoom siv kho kom zoo nkauj, cov vuas luaj ceramic tau dav siv thoob plaws ntiaj teb, thiab yuav ua li cas muab cov khoom siv ruaj khov no kom nws muaj kev nyab xeeb thiab ruaj khov ib txwm muaj kev txhawj xeeb ntawm tib neeg. Qhov tshwm sim ntawm cov nplais pobzeb adhesives, nyob rau hauv ib qho twg, qhov kev ntseeg ntawm cov nplais muab tshuaj txhuam yog lav.
Cov cwj pwm sib txawv ntawm kev tsim kho thiab kev tsim kho muaj qhov sib txawv ntawm kev tsim kho kev ua haujlwm rau cov nplais nplaum. Hauv kev tsim cov pobzeb hauv tsev tam sim no, cov txheej txheem tuab tuab (cov tshuaj nplaum ib txwm siv) tseem yog txoj hauv kev tsim kho. Thaum siv txoj kev no, qhov yuav tsum tau ua rau cov pobzeb nplaum: yooj yim rau do; yooj yim siv kua nplaum, tsis-stick riam; Zoo dua viscosity; zoo dua los tiv thaiv plam.
Nrog rau kev tsim cov pobzeb nplaum thev naus laus zis thiab kev txhim kho ntawm kev tsim kho tshuab, trowel method (nyias paste method) kuj maj mam txais. Siv txoj kev tsim kho no, qhov yuav tsum tau ua rau pobzeb nplaum: yooj yim rau do; nplaum riam; zoo dua los tiv thaiv kev ua haujlwm; zoo dua wettability rau cov vuas, qhib lub sij hawm ntev.
Feem ntau, xaiv ntau hom cellulose ether tuaj yeem ua rau cov pobzeb nplaum ua tiav qhov kev ua haujlwm tau zoo thiab kev tsim kho.
2. Cellulose ether siv hauv putty
Nyob rau hauv qhov pom kev zoo nkauj ntawm Orientals, qhov du thiab tiaj tus ntawm lub tsev feem ntau suav tias yog qhov zoo nkauj tshaj plaws. Daim ntawv thov ntawm putty li tau los ua. Putty yog cov txheej txheem nyias nyias uas ua lub luag haujlwm tseem ceeb hauv kev kho kom zoo nkauj thiab kev ua haujlwm ntawm lub tsev.
Peb txheej txheej txheej zoo nkauj: lub hauv paus phab ntsa, txheej txheej txheej txheej, thiab txheej txheej tiav muaj cov haujlwm tseem ceeb sib txawv, thiab lawv cov qauv elastic thiab deformation coefficient kuj txawv. Thaum lub ambient kub, av noo, thiab lwm yam hloov, lub deformation ntawm peb txheej ntawm cov ntaub ntawv tus nqi ntawm putty kuj txawv, uas yuav tsum tau lub putty thiab xov txheej cov ntaub ntawv kom muaj ib tug haum elastic modulus, cia siab rau lawv tus kheej elasticity thiab yooj kom tshem tawm cov concentrated kev nyuaj siab, thiaj li tiv thaiv tawg ntawm lub hauv paus txheej thiab tiv thaiv tev ntawm txheej txheej.
Lub putty nrog kev ua tau zoo yuav tsum muaj kev ua haujlwm zoo ntawm cov txheej txheem ntub dej, kev rov ua dua, kev ua haujlwm du, lub sijhawm ua haujlwm txaus thiab lwm yam kev tsim kho, thiab yuav tsum muaj kev sib koom ua ke zoo, ua tau zoo, thiab ua haujlwm ntev. Grindability thiab durability thiab lwm yam.
3. Cellulose ether siv hauv mortar zoo tib yam
Raws li qhov tseem ceeb tshaj plaws ntawm Tuam Tshoj txoj kev lag luam kev lag luam ntawm cov khoom siv hauv tsev, Tuam Tshoj txoj kev lag luam npaj sib xyaw mortar tau maj mam hloov los ntawm lub sijhawm qhia kev lag luam mus rau lub sijhawm loj hlob sai nyob rau hauv ob qho kev cuam tshuam ntawm kev lag luam nce qib thiab txoj cai cuam tshuam.
Kev siv cov mortar sib xyaw ua ke yog ib txoj hauv kev zoo los txhim kho qhov project zoo thiab kev tsim kho kom zoo; kev txhawb nqa thiab kev siv cov khoom sib xyaw ua ke yog qhov tsim nyog rau kev siv cov peev txheej, thiab yog ib qho tseem ceeb rau kev txhim kho kom ruaj khov thiab kev loj hlob ntawm kev lag luam ncig; Kev siv cov mortar sib xyaw ua ke tuaj yeem txo qhov kev ua haujlwm thib ob ntawm kev tsim vaj tsev, txhim kho qib ntawm kev tsim kho tshuab, txhim kho kev tsim kho, txo kev siv zog, thiab txo qis tag nrho lub zog siv ntawm cov tsev thaum txuas ntxiv txhim kho kev nplij siab ntawm qhov chaw nyob.
Nyob rau hauv cov txheej txheem ntawm kev lag luam ntawm cov khoom sib xyaw ua ke, cellulose ether plays lub luag haujlwm tseem ceeb.
Kev siv lub ntsiab lus ntawm cellulose ether ua rau nws muaj peev xwm ua kom muaj kev tsim kho ntawm cov khoom sib xyaw npaj txhij; cellulose ether nrog kev ua tau zoo tuaj yeem txhim kho kev tsim kho kev ua tau zoo, siv thiab txau cov tshuaj khib nyiab; nws lub peev xwm thickening tuaj yeem txhim kho cov nyhuv ntawm cov mortar ntub ntawm lub hauv paus phab ntsa. Nws tuaj yeem txhim kho lub zog sib txuas ntawm lub mortar; nws tuaj yeem kho lub sijhawm qhib ntawm lub mortar; nws lub peev xwm tuav dej tsis sib xws tuaj yeem txo qhov tshwm sim ntawm cov yas tawg ntawm cov tshuaj khib nyiab; nws tuaj yeem ua kom cov dej ntawm cov cement ua kom tiav, yog li txhim kho tag nrho cov txheej txheem lub zog.
Siv cov plastering mortar zoo tib yam ua piv txwv, raws li cov mortar zoo, cov mortar sib tov yuav tsum muaj kev tsim kho zoo: yooj yim rau do, zoo wettability rau lub hauv paus phab ntsa, du thiab tsis lo rau riam, thiab txaus lub sij hawm ua hauj lwm (Me ntsis poob ntawm qhov sib xws), yooj yim rau theem; Lub mortar hardened yuav tsum muaj lub zog zoo heev thiab qhov tsos: haum compressive zog, kev sib txuas lub zog nrog lub hauv paus phab ntsa, zoo durability, du nto, tsis hollowing, tsis muaj cracking, tsis txhob poob hmoov.
4. Cellulose ether siv nyob rau hauv caulk / hniav mortar
Raws li ib feem tseem ceeb ntawm cov pobzeb nteg qhov project, tus neeg sawv cev caulking tsis tsuas yog txhim kho tag nrho cov txiaj ntsig thiab qhov sib txawv ntawm cov pobzeb ntsib qhov project, tab sis kuj tseem ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov dej tsis zoo thiab impermeability ntawm phab ntsa.
Cov khoom siv pobzeb nplaum zoo, ntxiv rau cov xim nplua nuj, cov xim tsis sib xws thiab tsis muaj xim sib txawv, yuav tsum muaj cov haujlwm ntawm kev ua haujlwm yooj yim, lub zog ceev, qis shrinkage, tsis tshua muaj porosity, waterproof thiab impervious. Cellulose ether tuaj yeem txo qis qis qis qis thaum muab kev ua haujlwm zoo rau cov khoom sib koom ua ke, thiab cov cua nkag tau me me, thiab cov nyhuv ntawm cov cement hydration me me.
Kho kom zoo nkauj mortar yog ib hom tshiab ntawm cov khoom siv phab ntsa uas ua ke nrog kev kho kom zoo nkauj thiab kev tiv thaiv. Piv nrog cov khoom siv kho kom zoo nkauj ntawm phab ntsa xws li cov pob zeb ntuj, cov nplais pobzeb, xim thiab iav kab hlau rhuav phab ntsa, nws muaj qhov tshwj xeeb zoo.
Piv nrog cov xim: qib siab; Lub neej ntev, kev pabcuam lub neej ntawm cov tshuaj khib nyiab yog ob peb zaug lossis txawm tias ntau lub sijhawm ntawm cov xim, thiab nws muaj tib lub neej ntev li cov tsev.
Piv nrog cov vuas luaj ceramic thiab pob zeb ntuj: zoo li cov nyhuv zoo nkauj; lighter siv load; nyab xeeb dua.
Piv nrog iav ntaub thaiv phab ntsa: tsis muaj kev xav; nyab xeeb dua.
Cov khoom zoo nkauj mortar nrog kev ua haujlwm zoo yuav tsum muaj: kev ua haujlwm zoo heev; kev ruaj ntseg thiab txhim khu kev qha; kev sib raug zoo.
