HPMC thermal insulation mortar yog hais txog cov khoom siv hauv tsev uas tau hloov kho uasHydroxypropyl methylcellulose (HPMC)yog ntxiv rau ua ib qho khoom ntxiv rau cov tshuaj pleev thaiv cua sov. HPMC yog cov cellulose ether uas tsis yog ionic nrog kev khaws dej zoo, ua kom tuab, ua haujlwm tau zoo thiab sib txuas lus zoo. Nws tau siv dav hauv cov tshuaj pleev thaiv tsev, hmoov putty, nplaum pobzeb, tshuaj pleev thaiv cua sov thiab lwm yam teb.
1. Lub luag haujlwm ntawm HPMC hauv cov tshuaj rwb thaiv tsev thermal
Lub hom phiaj tseem ceeb ntawm kev ntxiv HPMC rau hauv cov tshuaj rwb thaiv tsev thermal yog los txhim kho nws txoj kev ua haujlwm, kev khaws dej, kev sib txuas thiab kev tiv thaiv kev sagging, xyuas kom meej tias nws yooj yim tsim, thiab muaj cov khoom siv kho tshuab zoo thiab ruaj khov tom qab hardening. Cov haujlwm tshwj xeeb yog raws li nram no:
1.1. Khaws dej tau zoo
HPMC tuaj yeem txhim kho qhov kev khaws cia dej ntawm cov mortar, zam kev poob dej sai thaum lub sijhawm tsim kho, xyuas kom muaj dej txaus ntawm cov cement, thiab yog li txhim kho lub zog sib txuas thiab lub zog tag nrho ntawm cov mortar.
1.2. Txhim kho kev ua haujlwm ntawm kev tsim kho
Vim yog qhov zoo ntawm lubricity thiab thickening effect ntawm HPMC, cov mortar yog mos dua, du, yooj yim rau kev thov thiab tsim, txo qhov tshwm sim ntawm splashing thiab poob tshauv, thiab txhim kho kev tsim kho kom zoo.
1.3. Kev nplaum zoo dua
HPMC tuaj yeem txhim kho qhov kev sib txuas ntawm cov mortar thiab txheej hauv paus, zam kev shedding thiab hollowing, thiab txhim kho kev ruaj khov ntawm tag nrho cov txheej rwb thaiv tsev.
1.4. Tiv thaiv kom tsis txhob poob qis
Thaum lub sijhawm tsim phab ntsa ntsug, HPMC tuaj yeem txhim kho qhov kev ua tau zoo tiv thaiv kev sagging ntawm cov mortar, yog li nws tseem ruaj khov thaum lub sijhawm tsim cov txheej tuab thiab tsis yooj yim rau swb.
2. Cov yam ntxwv ua tau zoo ntawm HPMC rwb thaiv tsev mortar
Lub teeb yuag thiab muaj zog heev: Cov pob zeb sib xyaw ua ke uas tsis muaj zog xws li cov perlite nthuav dav thiab cov iav ua npuas ncauj feem ntau yog ntxiv rau hauv cov mortar. Thaum siv nrog HPMC, ib txheej rwb thaiv tsev uas tsis hnyav thiab muaj zog heev tuaj yeem tsim tau.
Kev ua kom sov tsawg: Nws cov kev ua kom sov feem ntau yog nruab nrab ntawm 0.045 thiab 0.065 W / m · K, uas ua rau thaiv kev ua kom sov thiab txhim kho kev siv hluav taws xob ntawm cov tsev.
Kev tiv thaiv huab cua zoo: Nyob rau hauv qhov kev ua ntawm HPMC, qhov ruaj khov thiab tawg tsis kam ntawm cov thermal rwb thaiv tsev mortar tau zoo dua, thiab nws tuaj yeem hloov kho rau ntau yam kev hloov pauv huab cua.
Kev tiv thaiv ib puag ncig thiab tsis muaj tshuaj lom: HPMC yog cov khoom siv ntsuab thiab zoo rau ib puag ncig, uas sib xws nrog cov ntaub ntawv inorganic xws li cement thiab xuab zeb, thiab tsis tso tawm cov tshuaj lom.
3. Daim ntawv thov teb
Cov tshuaj txhuam rwb thaiv tsev HPMC siv dav hauv kev tsim kho phab ntsa sab nraud, kev rwb thaiv tsev phab ntsa sab hauv, kev rwb thaiv tsev ru tsev, thiab lwm yam ntawm ntau lub tsev. Nws yog qhov tshwj xeeb tshaj yog rau cov haujlwm kho dua tshiab uas txuag hluav taws xob, cov tsev nyob rau thaj chaw txias, cov tsev pej xeem, thiab lwm yam, uas muaj txiaj ntsig zoo rau kev txuag hluav taws xob thiab kev nplij siab hauv tsev.
4. Kev ceev faj txog kev tsim kho
Qhov piv tsim nyog: HPMC thermal insulation mortar yuav tsum tau npaj kom raug raws li qhov yuav tsum tau tsim thiab cov xwm txheej ntawm kev tsim kho, thiab qhov ntau ntawm HPMC yuav tsum tau tswj hwm feem ntau ntawm 0.2% thiab 0.5% (los ntawm cov hmoov qhuav).
Do kom sib npaug: Thaum do, cov khoom qhuav yuav tsum tau sib tov kom sib npaug ua ntej, tom qab ntawd yuav tsum ntxiv dej thiab do kom sib npaug, thiab tom qab ntawd do dua tom qab sawv rau ob peb feeb.
Kev tswj hwm ib puag ncig kev tsim kho: Tsis txhob tsim kho rau qhov kub thiab txias lossis cua hlob kom tiv thaiv cov dej noo ntawm cov mortar kom tsis txhob evaporate sai dhau thiab cuam tshuam rau cov nyhuv.
Kev kho lub hauv paus: Lub hauv paus yuav tsum huv, tsis muaj roj thiab plua plav, thiab ntub thaum tsim nyog kom ntseeg tau tias muaj kev sib txuas zoo.
Kev tswj qhov tuab ntawm kev tsim kho: Qhov tuab ntawm txhua daim plastering yuav tsum tsis txhob tuab dhau, feem ntau tswj tau hauv 1.5cm, thiab kev tsim cov txheej tuab yuav tsum tau ua tiav hauv cov pawg kom tiv thaiv kev tawg thiab hollowing.
HPMC thermal rwb thaiv tsev mortar, ua cov khoom siv hauv tsev txuag hluav taws xob nrog kev ua tau zoo heev, sib xyaw ua ke rwb thaiv tsev thermal, rwb thaiv tsev kub, kev tsim kho yooj yim, kev lag luam thiab kev tiv thaiv ib puag ncig, thiab siv dav hauv cov tsev ntsuab niaj hnub. Kev ntxiv ntawm HPMC tsis yog tsuas yog txhim kho kev ua tau zoo ntawm cov mortar, tab sis kuj lav qhov zoo ntawm kev tsim kho thiab kev ua haujlwm ntev. Nws yog ib txoj hauv kev tseem ceeb los txhawb kev txuag hluav taws xob hauv tsev thiab kev tsim kho zoo. Yav tom ntej, nrog rau kev txhim kho sai ntawm cov tsev ntsuab, HPMC thermal insulation mortar yuav ua lub luag haujlwm tseem ceeb hauv lub tsev txuag hluav taws xob.
