MHEC Hydroxyethyl Methyl Cellulose

Mawu Oyamba

CAS: 9032-42-2Hydroxyethyl Methyl Cellulose (MHEC) ndi madzi osungunuka a nonionic cellulose ethers, omwe amaperekedwa ngati ufa wopanda madzi kapena granular form cellulose. pansi pamikhalidwe yamchere popanda ziwalo za nyama, mafuta ndi zina za bioactive constituents.MHEC ikuwoneka ngati ufa woyera ndipo imakhala yopanda fungo komanso yosakoma.Amawonetsedwa ndi hygroscopicity ndipo samasungunuka m'madzi otentha, acetone, ethanol ndi toluene.M'madzi ozizira MHEC idzaphulika mu njira ya colloidal ndipo kusungunuka kwake sikukhudzidwa ndi mtengo wa PH. Zofanana ndi methyl cellulose pamene zikuwonjezeredwa ku magulu a Hdroxyethyl.MHEC imagonjetsedwa ndi saline, imasungunuka mosavuta m'madzi ndipo imakhala ndi kutentha kwa gel okwera.MHEC imadziwikanso kuti HEMC, Methyl Hydroxyethyl Cellulose, yomwe ingagwiritsidwe ntchito ngati wothandizira kwambiri posungira madzi, stabilizer, zomatira ndi kupanga mafilimu pomanga, zomatira matailosi, simenti ndi gypsum zochokera plasters, zotsukira madzi, ndi ntchito zina zambiri.

3.Munda wa Ntchito

1) Zomatira za matailosi

· Yambitsani zomatira matailosi nthawi yayitali yotsegula.

· Sinthani magwiridwe antchito popanda kumata trowel.

· Onjezani kusamvana ndi kunyowa.

2) pulasitala wopangidwa ndi simenti/gypsum

·Kuchuluka kwa kasungidwe ka madzi.

· Kuchita bwino kwambiri komanso kuchuluka kwa zokutira

· Kupititsa patsogolo anti-slip ndi anti-sagging

· Kutha kupirira kutentha

3)Kudzilimbitsa nokha

• Pewani kuti thonje lisakhazikike ndikutuluka magazi

·Kukonza malo osungira madzi

· Chepetsani kuchepa kwamatope

Pewani ming'alu

4) Wall Putty / Skim Coat

· Limbikitsani kasungidwe ka madzi a ufa wa putty, onjezani nthawi yogwira ntchito panja ndikuwongolera magwiridwe antchito.

· Kupititsa patsogolo kutsekereza madzi ndi permeability wa putty ufa.

· Sinthani zomatira ndi makina a ufa wa putty.

5) utoto wa latex

· Kukhuthala kwabwino, kumapereka magwiridwe antchito abwino kwambiri komanso kuwongolera kukana kwa zopakapaka.

· Kugwirizana kwabwino ndi ma emulsion a polima, zowonjezera zosiyanasiyana, ma pigment, ndi zodzaza, ndi zina zambiri.

· Kugwira ntchito bwino kwambiri komanso kukana kutayikira.

· Kusungidwa bwino kwa madzi, kubisala mphamvu ndi filimu kupanga zinthu zokutira kumakulitsidwa.

·Good rheological properties, kubalalitsidwa ndi kusungunuka.

6) Chotsukira zovala

·Kutumiza kwamphamvu kwambiri

· Kuchedwa kusungunuka kwa kuwongolera mamasukidwe akayendedwe

·Kumwazika madzi ozizira mwachangu

· Emulsification yabwino

· Kukhuthala kwakukulu

·Chitetezo ndi kukhazikika
