Nrog rau kev txhim kho ntawm ib puag ncig kev paub thiab kev xav tau ntawm cov khoom siv hauv tsev ua lag luam rau kev ua haujlwm thiab kev tiv thaiv ib puag ncig, cov khoom siv hauv tsev ib puag ncig tau maj mam dhau los ua cov khoom tseem ceeb hauv kev tsim kho. Cellulose ether, raws li cov khoom siv ntau yam polymer, ua lub luag haujlwm tseem ceeb hauv cov khoom siv hauv tsev nrog nws cov kev ua tau zoo. Muaj ntau ntau hom cellulose ethers, feem ntau yog hydroxypropyl methylcellulose (HPMC), methyl cellulose (MC), hydroxyethyl cellulose (HEC), thiab lwm yam. Lawv yog siv nyob rau hauv ib puag ncig tus phooj ywg lub tsev cov ntaub ntawv xws li lub tsev adhesives, putty hmoov. , qhuav-siv mortar thiab coatings los ntawm regulating hydration, txhim kho rheology thiab txhim kho cov khoom siv.
1. Cov yam ntxwv ntawm cellulose ethers
Cellulose ether yog ib qho polymer compound muab rho tawm los ntawm cov nroj tsuag ntuj fibers. Nws yog ua soluble, thickening, dej-retaining thiab film-forming los ntawm etherification cov tshuaj tiv thaiv. Nws cov yam ntxwv tseem ceeb muaj xws li:
Kev tuav dej: Cellulose ether muaj peev xwm tuav tau dej zoo, uas tuaj yeem tswj tau cov dej tso rau hauv cov khoom siv hauv tsev, tsis txhob muaj dej ntau dhau, thiab yog li txhim kho kev tsim kho.
Thickening: Cellulose ether feem ntau yog siv los ua cov thickener hauv cov khoom siv hauv tsev, uas tuaj yeem txhim kho cov viscosity ntawm cov khoom thiab txhim kho nws cov kev ua haujlwm thaum siv.
Adhesion: Nyob rau hauv qhuav-mixed mortar thiab adhesives, cellulose ether yuav siv tau raws li ib tug binder los txhim khu lub adhesion ntawm cov khoom thiab lub hauv paus.
Kev hloov kho Rheological: Cellulose ether tuaj yeem txhim kho rheological thaj chaw ntawm cov khoom siv hauv tsev, kom lawv muaj peev xwm tuav tau zoo fluidity thiab thixotropy nyob rau hauv ntau yam kev tsim kho, uas yooj yim rau kev tsim kho thiab molding.
Anti-sagging: Cellulose ether tuaj yeem txhim kho cov khoom tiv thaiv sagging ntawm cov khoom, tshwj xeeb tshaj yog thaum tsim cov phab ntsa ntsug, uas tuaj yeem tiv thaiv cov tshuaj khib nyiab lossis cov xim los ntawm sagging.
2. Kev siv cov cellulose ether hauv ib puag ncig cov ntaub ntawv hauv tsev
Qhuav-tso mortar
Qhuav-siv mortar yog ib qho khoom siv hauv tsev, feem ntau yog siv rau hauv phab ntsa plastering, pem teb theem, pobzeb nteg thiab lwm yam scenes. Cellulose ether yog dav siv nyob rau hauv qhuav sib tov mortar, feem ntau ua si lub luag hauj lwm ntawm dej tuav, thickening thiab bonding. Cellulose ether tuaj yeem ua rau cov mortar tso dej sib npaug thaum lub sijhawm ziab, tiv thaiv cov kab nrib pleb los ntawm cov dej ntau dhau, thiab txhim kho lub zog sib txuas ntawm cov mortar kom ntseeg tau tias nws lub zog thiab kav ntev tom qab kev tsim kho.
Architectural txheej
Cellulose ether yog siv los ua cov thickener thiab dej-txuas tus neeg sawv cev hauv cov dej-raws li vaj tse txheej txheej los txhim kho kev tsim kho kev ua haujlwm thiab cov txheej txheem kawg ntawm cov txheej txheem. Nws muaj cov yeeb yaj kiab zoo tshaj plaws thiab kev hloov kho rheological, uas tuaj yeem xyuas kom meej tias cov txheej txheem muaj kev sib kis tau zoo nyob rau hauv cov cuab yeej siv sib txawv. Tsis tas li ntawd, cellulose ether tuaj yeem txhim kho cov khoom tiv thaiv sagging ntawm cov txheej txheem, ua rau nws tsis tshua muaj sag thaum siv rau ntawm qhov chaw ntsug, yog li tau txais cov txheej txheem sib xws.
Cov nplaum nplaum
Pobzeb adhesives yog ib qho tseem ceeb daim ntawv thov nyob rau hauv lub tshav pob ntawm ib puag ncig tus phooj ywg lub tsev cov ntaub ntawv. Cellulose ethers tuaj yeem txhim kho cov dej tuav tau zoo thiab cov khoom tiv thaiv plam ntawm cov nplaum thiab txhim kho lub zog sib txuas ntawm cov vuas thiab cov txheej txheem. Thaum lub sij hawm tsim kho, qhov sib ntxiv ntawm cellulose ethers ho txhim kho kev ua haujlwm ntawm cov nplais nplaum, thaum tseem ua kom lub sijhawm qhib ntev dua, uas yooj yim rau cov neeg ua haujlwm kho.
Putty hmoov
Putty hmoov yog siv rau phab ntsa theem thiab kho. Cov dej tuav ntawm cellulose ether tuaj yeem tiv thaiv qhov tawg lossis poob tawm los ntawm putty qhuav sai sai tom qab kev tsim kho. Nyob rau tib lub sijhawm, nws cov cuab yeej thickening pab txhim kho cov txheej thiab smoothness ntawm putty, ua rau kev tsim kho smoother.
Self-leveling cov ntaub ntawv hauv pem teb
Daim ntawv thov ntawm cellulose ether nyob rau hauv nws tus kheej-leveling cov ntaub ntawv hauv pem teb yog tsuas yog los txhim kho nws cov fluidity thiab dej tuav, xyuas kom meej tias cov ntaub ntawv yuav tsum tau sai sai leveled thiab sib npaug zos rau hauv av tsim, thiab tiv thaiv lub hauv pem teb los ntawm cracking los yog sanding los ntawm dej poob.
3. Ib puag ncig zoo ntawm cellulose ether
Natural source, environmentally friendly ntau lawm
Cellulose ether yog tsim los ntawm ntuj cellulose thiab yog txuas ntxiv mus. Tsis muaj cov pa phem pov tseg thiab cov kua khib nyiab yog tsim los ntawm cov txheej txheem tsim khoom, thiab qhov cuam tshuam rau ib puag ncig me me. Tsis tas li ntawd, piv nrog cov tshuaj siv tshuaj ntxiv, cellulose ether tsis muaj teeb meem rau tib neeg lub cev thiab tuaj yeem ua rau tsis zoo. Nws yog ib yam khoom ntsuab tiag tiag thiab ib puag ncig tus phooj ywg.
Txo cov khoom siv zog siv thiab txhim kho kev tsim kho kom zoo
Cellulose ether tuaj yeem txhim kho kev tsim kho ntawm cov khoom siv hauv tsev, ua kom lawv cov kev tsim kho yooj yim dua thiab nrawm dua, thiab txo cov khoom pov tseg thiab siv zog. Tsis tas li ntawd, vim nws cov dej tuav tau zoo, cellulose ether tuaj yeem txo qhov kev thov ntawm cov dej hauv kev tsim kho thiab txuag cov peev txheej ntxiv.
Txhim kho qhov kav ntev ntawm cov khoom siv hauv tsev
Cellulose ether tuaj yeem txhim kho lub zog ntawm cov khoom siv hauv tsev, ua rau lub neej kev pab cuam ntawm lub tsev ntev dua, txo qhov xav tau kev kho lossis hloov pauv vim kev laus lossis kev puas tsuaj ntawm cov khoom siv hauv tsev, yog li txo cov peev txheej pov tseg thiab tsim cov khoom pov tseg.
Raws li ib puag ncig tus phooj ywg, muaj kev nyab xeeb thiab muaj txiaj ntsig cov khoom siv hauv tsev ntxiv, cellulose ether tau siv dav hauv ntau cov khoom siv hauv tsev xws li qhuav-siv mortar, pobzeb nplaum, thiab cov txheej txheem vaj tsev. Nws tuaj yeem tsis tsuas yog txhim kho kev tsim kho ntawm cov khoom siv hauv tsev thiab txhim kho cov ntaub ntawv zoo, tab sis kuj tseem muaj qhov zoo ntawm ib puag ncig zoo. Nyob rau yav tom ntej ntawm cov khoom siv hauv tsev, nrog kev txhim kho txuas ntxiv ntawm kev tiv thaiv ib puag ncig, daim ntawv thov kev cia siab ntawm cellulose ether yuav dav dua.
