Cellulose ether yog lub ntsiab additive ntawm lub teeb plastered gypsum, uas plays lub luag hauj lwm tseem ceeb nyob rau hauv lub teeb plastered gypsum. Txoj cai tsis yog rhiab rau plaster lub hauv paus ntawm cellulose ether HPMC cov khoom, tuaj yeem nkag mus rau hauv txhua yam khoom gypsum thiab yuav tsis tsim pawg, porosity ntawm plastering gypsum tom qab kho yam tsis muaj kev cuam tshuam tsis zoo, thiaj li ua kom muaj kev ua pa ntawm plastering gypsum. , retarding kev txiav txim tab sis tsis muaj kev cuam tshuam rau cov gypsum crystals loj hlob tuaj, nrog rau cov ntub dej viscous quab yuam kom cov khoom sib txuas muaj peev xwm, nyob rau hauv lub hauv paus nto zoo heev txhim kho kev tsim kho kev ua tau zoo ntawm cov khoom gypsum, ua rau lawv yooj yim rau kev sib kis tsis ua raws li cov cuab yeej.
Raws li koj paub, nyob rau hauv xyoo tas los no, nrog rau txoj kev loj hlob ntawm lub teb chaws thiab kho cov cai, txoj kev loj hlob ntawm ntsuab ib puag ncig tiv thaiv lub tsev ntaub ntawv tau dhau los ua qhov chaw kub, raws li nyob rau hauv tsev plastering cov ntaub ntawv tshiab, plastering gypsum yog nce highlighted, plastering gypsum yog. los hloov cov cement mortar ntawm cov khoom siv hluav taws xob tshiab, kev tiv thaiv ib puag ncig, kev lag luam, ob qho tib si lub zog ntawm cov cement, thiab piv rau cov cement noj qab haus huv kev tiv thaiv ib puag ncig, ruaj khov, Adhesive quab yuam loj, tsis yooj yim rau hmoov, tsis tawg, tsis khoob. nruas, tsis xau hmoov thiab lwm yam zoo, yooj yim rau siv, txuag nqi, lub teeb plaster gypsum yog tsuas yog raws li lub tsev plaster hmoov raws li cov khoom tseem ceeb, rau lub teeb perlite los yog iav hlaws dai raws li aggregate, ntxiv ntau yam ntaub ntawv plaster tshiab.
Cellulose ether Nws muaj qhov zoo hauv qab no:
Ua ntej, kho cov av noo, thaum sab nraud cov av noo siab dua cov av noo ntawm plaster plaster, vim hais tias sab nraud vapor siab siab dua nws cov saturated vapor siab, txhawb kev ua haujlwm sab hauv ntawm adsorption ntawm dej, thiaj li ncua qhov nce ntawm cov av noo. av noo; Thaum cov av noo sab nraud qis dua qhov sib piv ntawm cov av ntawm plastered gypsum, lub vapor siab sab nraud yog qis dua nws cov saturated vapor siab, ua rau evaporation ntawm sab hauv dej molecules. Yog li ntawd, nws tuaj yeem ua lub luag haujlwm ntawm kev kho thiab tswj cov av noo.
Thib ob, cov nplaim hluav taws xob zoo. Qhov hnyav molecular ntawm dihydrous gypsum yog 172, thiab qhov hnyav molecular ntawm cov dej yog 18. Thaum lub tsev ntawm 100m2 ntsib hluav taws, thaum kub txog 110 ℃ lossis siab dua, dihydrous gypsum yuav sai sai tso cov dej siv lead ua rau hauv semihydrous gypsum thiab tom qab ntawd hloov ntxiv. mus rau hauv anhydrous gypsum, uas tso tau 560kg dej. Dej tuaj yeem nqus tau cua sov ntau hauv cov txheej txheem evaporation. Nws tuaj yeem tiv thaiv qhov kub ntawm chav tsev sai sai thiab txhim kho txoj hauv kev ntawm kev khiav.
Thib peb, ntsuab ib puag ncig tiv thaiv. Gypsum tom qab kev kho mob tsis zoo, tsis muaj cov kuab paug tsis zoo, kev siv cov khoom siv tsis zoo hauv cov gel, cov khoom siv ntxiv yog cov khoom tiv thaiv ib puag ncig, ua los ntawm lub teeb plaster gypsum tsis tso tawm formaldehyde thiab lwm yam teeb meem, ntsuab ib puag ncig tiv thaiv, kev nyab xeeb thiab so assured.
Plaub, rwb thaiv tsev kub, txuag hluav taws xob, suab nqus, cuam tshuam tsis kam. Lub thermal conductivity ntawm plastering plaster yog 0.17W / (MK), yog li cov thermal conductivity ntawm plastering plaster yog 20% ntawm cov tsoos cement plastering mortar, uas muaj ib co thermal rwb thaiv tsev nyhuv thiab yuav txo tau lub zog noj ntawm lub tsev. Plastering gesso yog nyob rau hauv cov txheej txheem condense, sab hauv tsim qhov sib txawv me me, vim hais tias qhov no tuaj yeem ua rau lub suab nrov, tuaj yeem tiv thaiv lub zog ntawm lub zog rau qhov project dua, tuaj yeem hloov suab lub zog rau hauv lub zog hluav taws xob, muaj lub suab rwb thaiv tsev zoo. Vim yog cov qauv ntxeem tau tom qab condensation, nws tuaj yeem nqus tau qhov cuam tshuam lub zog, yog li nws yuav tsis tawg thiab poob thaum raug cuam tshuam.
Plastering gypsum nrog cellulose ether feem ntau muaj cov yam ntxwv hauv qab no:
1, kev tsim kho zoo heev: scraping yooj yim, du, tuaj yeem ua molding, nrog plasticity.
2, txhim kho plaster mortar txheej tus nqi: piv nrog cov cellulose ether zoo sib xws, txheej txheej tau nce ntau.
3, kev ua tau zoo los tiv thaiv kev ua haujlwm: tuab txheej scraping ib qho kev tsim kho tsis ntws dai, ntau tshaj ob zaug (ntau tshaj 3cm) scraping tsis poob, zoo heev plasticity.
4, cov dej tuav tau zoo heev: ncua lub sijhawm ua haujlwm ntawm gypsum puag, txhim kho huab cua tsis kam ntawm gypsum puag, ua kom lub zog sib txuas ntawm gypsum puag thiab hauv paus, kev ua haujlwm ntub dej zoo heev, txo cov av tshauv.
5, muaj zog compatibility: haum rau txhua yam ntawm gypsum puag, txo cov laus lub sij hawm ntawm gypsum, txo lub qhuav shrinkage tus nqi, lub phab ntsa tsis yooj yim rau khoob nruas, tawg.
6, daim ntawv thov teb thiab tus nqi: lub teeb hauv qab plaster gypsum, pom zoo noj 0.18% - 0.25%.
Plastering gypsum nrog cellulose ether yog ua los ntawm high quality refined paj rwb los ntawm etherification cov tshuaj tiv thaiv, non-ionic cellulose ether, ruaj khov lub cev, yuav tsis tsim tshuaj tiv thaiv nrog rau lwm yam raw cov ntaub ntawv thiab tsim ib co teeb meem tshuaj, environmentally friendly, tsis muaj kev cuam tshuam rau tib neeg noj qab haus huv, nyob rau hauv plastering gypsum yog ib hom ntsuab zog txuag additives, KIMA yeej ib txwm yog lub tswv yim ntawm ntsuab ib puag ncig tiv thaiv thiab kev txuag hluav taws xob rau hauv lub tuam txhab cov khoom thiab kev tswj, peb tawm tswv yim kev txhim kho kom ruaj khov, teb rau lub teb chaws hu, ntsuab roob yog kub thiab nyiaj. roob, KIMA yuav siv cov khoom zoo cellulose ether los pab lub ntiaj teb no los tsim ntsuab ib puag ncig tiv thaiv sab hauv phab ntsa plastering cov ntaub ntawv.
