Kima Gypsum Hydroxypropyl Methyl Cellulose Khoom Nta

01. Khoom nta ntawm Kima gypsum-based hydroxypropyl methylcellulose:

1. Txhim kho qhov sib kis ntawm gypsum puag: Muab piv nrog cov hydroxypropyl methylcellulose ether zoo sib xws, qhov sib kis tau nce ntau.

2. 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.

3. Kev ua tau zoo los tiv thaiv sag: nws yuav tsis sag thaum nws dai rau hauv ib txheej thaum nws dai rau hauv ib txheej tuab, thiab nws yuav tsis sag thaum nws dai rau hauv ntau tshaj ob txheej (ntau tshaj 3cm), thiab nws muaj plasticity zoo heev.

4. Zoo heev constructability: yooj yim thiab du thaum dai, tuaj yeem molded ib zaug, thiab muaj plasticity.

5. Cov dej tuav tau zoo: 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 txheej txheej, kev ua haujlwm ntub dej zoo heev, thiab txo cov av tshauv.

6. Strong compatibility: Nws yog haum rau txhua yam ntawm gypsum puag, txo lub sij hawm sinking ntawm gypsum, txo qhov qhuav shrinkage tus nqi, thiab phab ntsa nto tsis yooj yim rau hollow thiab tawg.

02. Daim ntawv thov kev sim xeem:

1. Kev ntsuas dej tuav: xa mus rau tus qauv GB / T28627-2012 "Plastering Gypsum", cov dej tuav tus nqi ntawm lub teeb hauv qab plastering gypsum yog ≥ 60%, thaum Kima gypsum-based hydroxypropyl methylcellulose ntxiv 0.2% thiab 0.25%, muaj cov khoom tuav dej zoo heev.

2. Phab ntsa dai kev sim: nws yog lub teeb thiab du thaum dai, thiab tuaj yeem ua pwm rau ib zaug. Qhov saum npoo yog muag heev thiab mos, nrog ci.

3. Anti-sagging test: Nws yuav tsis sag thaum nws dai rau hauv ib txheej thaum nws yog dai rau hauv ib txheej tuab, thiab nws yuav tsis sag thaum nws dai rau hauv ob lossis ntau txheej (ntau tshaj 3cm), thiab nws muaj zoo heev plasticity.

4. Kev ntsuas lub zog: Tom qab kev sim, Kima gypsum-based hydroxypropyl methylcellulose muaj lub zog tensile zoo heev thiab compressive zog.

5. 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 muaj phab ntsa ntawm 10mm tuab. Kev siv Kima gypsum-based hydroxypropyl methylcellulose cov khoom 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.
