Raws li kev tsim kho kev lag luam txuas ntxiv mus ntxiv rau kev tiv thaiv ib puag ncig thiab kev txhim kho kom ruaj khov, kev tiv thaiv ib puag ncig ntawm cov khoom siv hauv tsev tau dhau los ua qhov tseem ceeb ntawm kev tshawb fawb. Mortar yog ib yam khoom siv hauv kev tsim kho, thiab nws txoj kev txhim kho thiab kev tiv thaiv ib puag ncig tau txais kev saib xyuas ntau dua.Hydroxypropyl methylcellulose (HPMC), raws li kev siv ntau ntxiv, tuaj yeem tsis tsuas yog txhim kho kev tsim kho ntawm mortar, tab sis kuj txhim kho kev tiv thaiv ib puag ncig ntawm mortar rau qee yam.
1. Cov yam ntxwv tseem ceeb ntawm HPMC
HPMC yog cov dej-soluble polymer compound chemically modified los ntawm natural plant fibers (xws li ntoo pulp los yog paj rwb). Nws muaj cov thickening zoo heev, film-forming, dej tuav, gelling thiab lwm yam khoom. Vim nws txoj kev ruaj ntseg zoo, tsis muaj tshuaj lom, tsis muaj ntxhiab thiab degradable, AnxinCel®HPMC tau siv dav hauv kev tsim kho, tshwj xeeb tshaj yog hauv mortar. Raws li cov khoom siv ntsuab thiab ib puag ncig tus phooj ywg, HPMC muaj qhov cuam tshuam loj rau kev tiv thaiv ib puag ncig kev ua haujlwm ntawm mortar.
2. Kev txhim kho ntawm kev siv tshuaj khib nyiab los ntawm HPMC
Ib puag ncig tus phooj ywg mortar tsis tsuas yog yuav tsum tau ua kom tau raws li lub zog thiab ua haujlwm ntawm lub hauv paus, tab sis kuj muaj kev tsim kho zoo. Qhov sib ntxiv ntawm HPMC tuaj yeem txhim kho kev tsim kho ntawm mortar, tshwj xeeb hauv qab no:
Kev tuav dej: HPMC tuaj yeem ua kom cov dej khaws cia ntawm mortar thiab tiv thaiv kom tsis txhob muaj dej evaporation ntxov, yog li txo cov teeb meem xws li tawg thiab voids los ntawm kev poob dej sai. Cov khib nyiab nrog cov dej tuav tau zoo ua rau cov khoom pov tseg tsawg dua thaum lub sij hawm hardening, yog li txo qhov tsim cov khoom pov tseg thiab muaj kev tiv thaiv ib puag ncig zoo dua.
Fluidity: HPMC txhim kho qhov fluidity ntawm mortar, ua rau kev tsim kho smoother. Nws tsis tsuas yog txhim kho kev ua haujlwm ntawm kev ua haujlwm, tab sis kuj txo cov khoom pov tseg hauv kev tuav haujlwm. Los ntawm kev txo cov khoom pov tseg, kev siv peev txheej txo qis, uas yog raws li lub tswv yim ntawm lub tsev ntsuab.
Txuas lub sijhawm qhib: HPMC tuaj yeem txuas ntxiv lub sijhawm qhib ntawm mortar, txo cov khib nyiab tsis tsim nyog thaum lub sijhawm tsim kho, zam kev noj ntau dhau ntawm qee cov khoom siv, thiab yog li txo lub nra ntawm ib puag ncig.
3. Cov nyhuv ntawm HPMC rau lub zog thiab kav ntev ntawm mortar
Lub zog thiab durability ntawm mortar yog ncaj qha ntsig txog kev nyab xeeb thiab kev pabcuam lub neej ntawm lub tsev. HPMC tuaj yeem txhim kho cov khoom siv kho tshuab thiab ua haujlwm ntev ntawm cov tshuaj khib thiab cuam tshuam tsis ncaj rau kev ua haujlwm ib puag ncig:
Txhim kho lub zog compressive thiab kev sib txuas ntawm cov tshuaj khib nyiab: Qhov sib ntxiv ntawm HPMC tuaj yeem txhim kho lub zog compressive thiab kev sib txuas ntawm cov khib nyiab, txo qhov xav tau kev kho thiab hloov pauv vim muaj teeb meem zoo hauv cov khoom siv hauv tsev thaum siv lub tsev. Txo kev kho thiab hloov pauv txhais tau hais tias tsawg dua cov peev txheej thiab muaj txiaj ntsig zoo rau ib puag ncig.
Txhim kho qhov permeability thiab Frost tsis kam ntawm mortar: Tom qab ntxiv HPMC rau hauv mortar, nws permeability thiab Frost kuj tau txhim kho. Qhov no tsis yog tsuas yog txhim kho lub kav ntev ntawm cov mortar, tab sis kuj txo qhov kev puas tsuaj los ntawm ib puag ncig hnyav lossis cov khoom laus. Kev siv peev txheej. mortars nrog zoo durability txo cov kev siv ntawm natural resources, yog li txo lub nra ntawm ib puag ncig.
4. Qhov cuam tshuam ntawm HPMC rau ib puag ncig tus phooj ywg ntawm mortar
Raws li cov kev cai ntawm ib puag ncig cov ntaub ntawv hauv tsev, mortar yog ib qho khoom siv hauv tsev. Nws kev tiv thaiv ib puag ncig yog feem ntau cuam tshuam hauv cov hauv qab no:
Txo qhov tso tawm cov khoom tsis zoo: AnxinCel®HPMC yog tshuaj hloov kho los ntawm cov nroj tsuag ntuj fibers thiab tsis muaj tshuaj lom thiab tsis muaj mob. Kev siv HPMC hauv mortar los hloov qee cov tshuaj ntxiv tuaj yeem txo qis kev tso tawm ntawm qee yam teeb meem, xws li volatile organic compounds (VOCs) thiab lwm yam tshuaj phem. Qhov no tsis tsuas yog pab txhim kho huab cua zoo hauv tsev, tab sis kuj txo cov pa phem ib puag ncig.
Txhawb kev txhim kho kom ruaj khov: HPMC yog cov khoom siv txuas ntxiv tau los ntawm cov nroj tsuag ntuj fibers thiab muaj lub nra hnyav dua li cov khoom siv roj av. Nyob rau hauv cov ntsiab lus ntawm kev tsim kho kev lag luam tawm tswv yim txog kev tiv thaiv ib puag ncig ntsuab, kev siv HPMC tuaj yeem txhawb kev tsim kho kom ruaj khov ntawm cov khoom siv hauv tsev thiab ua raws li kev coj noj coj ua ntawm kev txuag cov peev txheej thiab kev tsim kho ib puag ncig.
Txo cov khoom pov tseg: Vim tias HPMC txhim kho kev tsim kho ntawm mortar, nws txo cov khoom pov tseg thaum lub sij hawm tsim kho. Tsis tas li ntawd, kev txhim kho durability ntawm mortar kuj txhais tau tias lub tsev yuav tsis tsim cov khib nyiab ntau dhau thaum siv. Txo kev tsim cov khoom pov tseg hauv kev tsim kho yuav pab txo qis kev tsim khoom pov tseg emissions.
5. Kev soj ntsuam ib puag ncig ntawm HPMC
Txawm tiasHPMCmuaj kev ua tau zoo ib puag ncig hauv mortar, nws cov txheej txheem tsim khoom tseem muaj qee yam kev cuam tshuam ib puag ncig. Kev tsim tawm ntawm HPMC yuav tsum tau hloov kho ntawm cov nroj tsuag fibers los ntawm cov tshuaj tiv thaiv. Cov txheej txheem no tuaj yeem koom nrog qee yam kev siv hluav taws xob thiab cov pa roj pov tseg. Yog li ntawd, thaum siv HPMC, nws yog ib qho tsim nyog yuav tsum ntsuas qhov kev tiv thaiv ib puag ncig ntawm nws cov txheej txheem tsim khoom thiab siv cov kev ntsuas coj los txo nws cov kev cuam tshuam ib puag ncig. Kev tshawb fawb yav tom ntej tuaj yeem tsom mus rau kev txhim kho ntawm HPMC cov thev naus laus zis ntau lawm ib puag ncig thiab kev tshawb nrhiav kev hloov ntsuab rau HPMC hauv mortar.
Raws li ntsuab thiab ib puag ncig tus phooj ywg kev tsim kho ntxiv, AnxinCel®HPMC muaj qhov cuam tshuam tseem ceeb rau kev ua haujlwm ib puag ncig ntawm mortar. Nws tuaj yeem tsis tsuas yog txhim kho kev tsim kho ntawm mortar, ua kom nws lub zog thiab ua haujlwm ntev, tab sis kuj txo qis kev tso tawm cov khoom tsis zoo, txhawb kev txhim kho kom ruaj khov thiab txo cov emission ntawm kev tsim cov khib nyiab. Txawm li cas los xij, cov txheej txheem tsim khoom ntawm HPMC tseem muaj qee yam kev cuam tshuam ib puag ncig, yog li nws yog qhov yuav tsum tau ua kom zoo dua nws cov txheej txheem tsim khoom thiab txhawb nqa daim ntawv thov ntawm ntsuab ntau lawm technology. Nyob rau hauv lub neej yav tom ntej, nrog rau kev nce qib ntawm kev tiv thaiv ib puag ncig technology, HPMC yuav siv dav hauv cov khoom siv hauv tsev, ua kom muaj txiaj ntsig ntau dua rau kev ua tiav ntawm cov vaj tsev ntsuab thiab cov vaj tsev zoo nkauj.
