Raws li kev lag luam kev tsim kho tseem niaj hnub them sai sai rau kev tiv thaiv ib puag ncig thiab kev txhim kho kom ruaj khov, kev tiv thaiv ib puag ncig ntawm cov ntaub ntawv tsim kho tau dhau los ua qhov tseem ceeb ntawm kev tshawb fawb. Mortar yog ib yam khoom siv hauv kev tsim kho, thiab nws cov kev txhim kho kev ua tau zoo thiab kev tiv thaiv ib puag ncig tau txais kev saib xyuas ntau dua.Hydroxypropyl methylcellulose (HPMC), raws li cov khoom siv tsim kho feem ntau, tsis yog tsuas yog txhim kho kev ua tau zoo ntawm cov mortar, tab sis kuj txhim kho kev tiv thaiv ib puag ncig ntawm cov mortar rau qee qhov twg.
1. Cov yam ntxwv tseem ceeb ntawm HPMC
HPMC yog ib qho polymer uas yaj tau hauv dej uas tau hloov kho los ntawm cov nroj tsuag ntuj (xws li ntoo pulp lossis paj rwb). Nws muaj cov khoom zoo heev uas ua rau tuab, ua zaj duab xis, khaws dej, gelling thiab lwm yam. Vim nws ruaj khov zoo, tsis muaj tshuaj lom, tsis muaj ntxhiab thiab lwj tau, AnxinCel®HPMC yog siv dav hauv kev tsim kho, tshwj xeeb tshaj yog hauv cov mortar. Ua ib yam khoom ntsuab thiab zoo rau ib puag ncig, HPMC muaj feem cuam tshuam loj heev rau kev ua haujlwm tiv thaiv ib puag ncig ntawm mortar.
2. Kev txhim kho kev ua haujlwm ntawm cov mortar los ntawm HPMC
Cov tshuaj mortar uas zoo rau ib puag ncig tsis yog tsuas yog xav tau kom ua tau raws li lub zog thiab kev ruaj khov ntawm lub hauv paus xwb, tab sis kuj muaj kev ua tau zoo ntawm kev tsim kho. Kev ntxiv HPMC tuaj yeem txhim kho kev ua tau zoo ntawm cov tshuaj mortar, tshwj xeeb tshaj yog raws li hauv qab no:
Kev khaws dej: HPMC tuaj yeem ua rau kom cov dej khaws cia ntawm cov pob zeb mortar thiab tiv thaiv kom tsis txhob muaj dej evaporation ua ntej lub sijhawm, yog li txo cov teeb meem xws li cov kab nrib pleb thiab qhov khoob uas tshwm sim los ntawm kev poob dej sai. Cov pob zeb mortar uas khaws dej zoo tsim cov khib nyiab tsawg dua thaum lub sijhawm ua kom tawv, yog li txo cov khib nyiab tsim kho thiab muaj cov txiaj ntsig zoo dua rau kev tiv thaiv ib puag ncig.
Kev Ua Tau Yooj Yim: HPMC txhim kho kev ua tau yooj yim ntawm cov mortar, ua rau cov txheej txheem tsim kho du thiab zoo dua. Nws tsis tsuas yog txhim kho kev ua haujlwm zoo xwb, tab sis kuj txo cov khib nyiab hauv kev ua haujlwm tes. Los ntawm kev txo cov khib nyiab ntawm cov ntaub ntawv, kev siv cov peev txheej raug txo qis, uas yog raws li lub tswv yim ntawm kev tsim kho ntsuab.
Ntev lub sijhawm qhib: HPMC tuaj yeem ntev lub sijhawm qhib ntawm cov tshuaj khib, txo cov khib nyiab tsis tsim nyog thaum lub sijhawm tsim kho, zam kev siv ntau dhau ntawm qee cov ntaub ntawv tsim kho, thiab yog li txo qhov hnyav rau ib puag ncig.
3. Cov nyhuv ntawm HPMC rau lub zog thiab kev ruaj khov ntawm cov mortar
Lub zog thiab kev ruaj khov ntawm cov mortar muaj feem cuam tshuam ncaj qha rau kev nyab xeeb thiab lub neej ua haujlwm ntawm lub tsev. HPMC tuaj yeem txhim kho cov khoom siv kho tshuab thiab kev ruaj khov ntawm cov mortar thiab cuam tshuam tsis ncaj qha rau kev ua haujlwm ib puag ncig:
Txhim kho lub zog compressive thiab lub zog sib txuas ntawm cov mortar: Kev ntxiv HPMC tuaj yeem txhim kho lub zog compressive thiab lub zog sib txuas ntawm cov mortar, txo qhov xav tau kev kho thiab hloov pauv vim muaj teeb meem zoo hauv cov ntaub ntawv tsim kho thaum siv lub tsev. Kev txo qis kev kho thiab hloov pauv txhais tau tias pov tseg cov peev txheej tsawg dua thiab muaj txiaj ntsig zoo rau ib puag ncig.
Txhim kho qhov permeability thiab te tsis kam ntawm mortar: Tom qab ntxiv HPMC rau hauv mortar, nws qhov permeability thiab te tsis kam tau zoo dua. Qhov no tsis yog tsuas yog txhim kho qhov ruaj khov ntawm mortar, tab sis kuj txo qhov puas tsuaj los ntawm ib puag ncig hnyav lossis cov khoom siv laus. Kev siv cov peev txheej. Cov mortars nrog kev ruaj khov zoo dua txo qhov kev siv cov peev txheej ntuj, yog li txo qhov hnyav ntawm ib puag ncig.
4. Qhov cuam tshuam ntawm HPMC rau kev phooj ywg ib puag ncig ntawm cov tshuaj khib
Raws li qhov yuav tsum tau ua ntawm cov khoom siv hauv tsev uas zoo rau ib puag ncig, cov pob zeb mortar yog cov khoom siv hauv tsev uas siv ntau. Nws txoj kev tiv thaiv ib puag ncig feem ntau yog pom tseeb hauv cov hauv qab no:
Txo qhov tso tawm cov tshuaj lom neeg: AnxinCel®HPMC yog hloov kho los ntawm cov nroj tsuag ntuj thiab tsis muaj tshuaj lom thiab tsis muaj teeb meem. Kev siv HPMC hauv cov tshuaj mortar los hloov qee cov tshuaj ntxiv ib txwm muaj tuaj yeem txo qhov tso tawm ntawm qee cov tshuaj lom neeg, xws li cov organic sib xyaw ua ke (VOCs) thiab lwm yam tshuaj lom neeg. Qhov no tsis yog tsuas yog pab txhim kho huab cua hauv tsev xwb, tab sis kuj txo cov pa phem ib puag ncig.
Txhawb kev txhim kho kom ruaj khov: HPMC yog cov khoom siv rov ua dua tshiab los ntawm cov nroj tsuag ntuj thiab muaj lub nra hnyav me dua li cov khoom lag luam petrochemical. Hauv cov ntsiab lus ntawm kev lag luam kev tsim kho uas tawm tswv yim rau kev tiv thaiv ib puag ncig ntsuab, kev siv HPMC tuaj yeem txhawb kev txhim kho kom ruaj khov ntawm cov ntaub ntawv tsim kho thiab ua raws li kev coj ua ntawm kev txuag cov peev txheej thiab kev txhim kho ib puag ncig zoo.
Txo cov khib nyiab hauv kev tsim kho: Vim tias HPMC txhim kho kev ua haujlwm ntawm cov pob zeb mortar, nws txo cov khib nyiab thaum lub sijhawm tsim kho. Tsis tas li ntawd, qhov kev txhim kho ntawm cov pob zeb mortar kuj txhais tau tias lub tsev yuav tsis tsim cov pob zeb mortar pov tseg ntau dhau thaum siv. Kev txo cov khib nyiab hauv kev tsim kho pab txo cov pa phem ntawm kev tsim kho.
5. Kev Ntsuam Xyuas Kev Cuam Tshuam Ib Puag Ncig ntawm HPMC
Txawm hais tiasHPMCmuaj kev ua tau zoo rau ib puag ncig hauv cov mortar, nws cov txheej txheem tsim khoom tseem muaj qee qhov cuam tshuam rau ib puag ncig. Kev tsim khoom ntawm HPMC xav tau kev hloov kho ntawm cov nroj tsuag ntuj los ntawm kev tshuaj lom neeg. Cov txheej txheem no yuav cuam tshuam nrog qee qhov kev siv hluav taws xob thiab cov pa roj pov tseg. Yog li ntawd, thaum siv HPMC, nws yog qhov tsim nyog los soj ntsuam kev tiv thaiv ib puag ncig ntawm nws cov txheej txheem tsim khoom thiab ua cov kev ntsuas kom txo nws cov kev cuam tshuam rau ib puag ncig. Kev tshawb fawb yav tom ntej tuaj yeem tsom mus rau kev tsim cov thev naus laus zis tsim khoom HPMC uas zoo rau ib puag ncig thiab kev tshawb nrhiav cov kev xaiv ntsuab rau HPMC hauv mortar.
Ua ib yam khoom siv ntxiv rau kev tsim kho uas ntsuab thiab zoo rau ib puag ncig, AnxinCel®HPMC muaj feem cuam tshuam tseem ceeb rau kev ua haujlwm ib puag ncig ntawm cov mortar. Nws tsis tsuas yog txhim kho kev ua haujlwm ntawm cov mortar, ua rau nws lub zog thiab kev ruaj khov, tab sis kuj txo qhov tso tawm ntawm cov tshuaj lom neeg, txhawb kev txhim kho kom ruaj khov thiab txo qhov tso tawm ntawm cov khib nyiab tsim kho. Txawm li cas los xij, cov txheej txheem tsim khoom ntawm HPMC tseem muaj qee qhov cuam tshuam rau ib puag ncig, yog li nws yog qhov tsim nyog los txhim kho nws cov txheej txheem tsim khoom thiab txhawb kev siv cov thev naus laus zis tsim khoom ntsuab. Yav tom ntej, nrog kev nce qib ntawm cov thev naus laus zis tiv thaiv ib puag ncig, HPMC yuav siv dav dua hauv cov ntaub ntawv tsim kho, ua rau muaj kev pab ntau dua rau kev ua tiav ntawm cov tsev ntsuab thiab cov tsev zoo rau ib puag ncig.
