Daim ntawv thov kev sim ntsuas ntawm hydroxypropyl methylcellulose:
1. Kev kuaj lub zog: Tom qab kev sim, gypsum-based hydroxypropyl methylcellulose muaj lub zog tensile zoo thiab compressive zog.
2. Anti-sagging test: Tsis muaj sag thaum ib qho kev tsim kho yog siv rau hauv cov khaubncaws sab nraud povtseg, thiab tsis muaj sag thaum thov rau ntau tshaj ob qhov kev hla (txog 3cm), thiab cov yas zoo.
3. Phab ntsa dai kev sim: nws yog lub teeb thiab du thaum dai, thiab tuaj yeem molded ib zaug. Qhov saum npoo yog muag heev thiab mos, nrog ci.
4. Kev sib kis tus nqi: Kev sib kis tus nqi ntawm gypsum puag yog hais txog cov txiaj ntsig tau los ntawm kev ntsuas qhov ntub dej ntom ntom ntawm gypsum puag. Ib tuj ntawm gypsum-based khoom rau kev tsim kho ntawm 10 hli tuab phab ntsa.
5. Kev ntsuas dej tuav: dej tuav tus nqi siv tus qauv GB / T28627-2012 "Plastering Gypsum", cov dej tuav tus nqi ntawm lub teeb hauv qab plastering gypsum yog ntau dua lossis sib npaug li 60%, thiab 0.2% thiab 0.25% ntawm gypsum-based hydroxypropyl methylcellulose ntxiv Nws muaj cov dej tuav tau zoo.
Cov yam ntxwv ntawmHydroxypropyl methylcellulose nyob rau hauv gypsum mortar:
1. Kev tsim kho zoo: nws yooj yim thiab du rau dai, tuaj yeem molded ib zaug, thiab muaj plasticity tib lub sijhawm.
2. Strong compatibility: Nws yog haum rau txhua yam ntawm gypsum bases, thiab yuav txo tau lub sij hawm sinking ntawm gypsum, txo qhov qhuav shrinkage tus nqi, thiab cov phab ntsa tsis yooj yim rau hollow thiab tawg.
3. Cov dej tuav tau zoo: nws tuaj yeem ua kom ntev lub sijhawm ua haujlwm ntawm gypsum puag, txhim kho lub thickness tiv thaiv ntawm gypsum puag, nce lub zog sib txuas ntawm gypsum puag thiab txheej txheej, zoo ntub kev sib txuas ua haujlwm, thiab txo cov av tshauv thiab lwm yam teeb meem.
4. Txhim kho qhov sib kis ntawm gypsum puag: Muab piv nrog cov hydroxypropyl methylcellulose ether zoo sib xws, tus nqi sib kis yuav nce ntxiv. Cov khoom siv Hydroxypropyl methylcellulose tuaj yeem ua rau cov txheej txheem ntau ntxiv, tuaj yeem npog ntau thaj chaw, tuaj yeem txo kev siv zog, txuag cov ntaub ntawv, thiab txhim kho cov txiaj ntsig kev lag luam.
5. Kev ua haujlwm zoo los tiv thaiv sagging: thaum dai cov khaubncaws sab nraud povtseg, ib leeg dhau kev tsim kho yuav tsis sag, thiab ntau tshaj ob kis, siab dua 3cm, yuav tsis sag thaum dai, thiab cov yas zoo.
6. Daim ntawv thov teb thiab ntau npaum li cas: Lub teeb hauv qab plastering gypsum, qhov pom zoo npaum li cas yog 2.5-3.5 kg / tuj.
