Detergent Thickener Hydroxypropyl Methyl Cellulose Ether HPMC
Kukhuthala kwakukuluMtengo wa HPMChydroxypropyl methyl celluloseThickenerKwa putty powder:
1) Mawonekedwe:Mtengo wa HPMCndi nonionic cellulose etha, woyera imvi-woyera ufa kapena granule, fungo ndi kukoma, sungunuka m'madzi ozizira, glacial acetic acid, Mowa, methanol ndi propylene glycol, sungunuka pang'ono mu acetone kutengera mlingo wa m'malo, pafupifupi sungunuka m'madzi otentha. , ethylene glycol ndi toluene.HPMC ndi kusungunuka mu osakaniza 10% methanol ndi 90% methylene kolorayidi kupanga colloidal njira.
2) Yankho la HPMC lili ndi zochitika zapamtunda, zowonekera kwambiri, komanso magwiridwe antchito okhazikika.Ukatenthedwa pa kutentha kwina, yankho limakhala lamitambo kapena limapanga gel osakaniza.Komabe, yankho limawonekeranso pambuyo pozizira.Mitundu yosiyanasiyana ya HPMC imakhala ndi kutentha kosiyana kwa gelation.Kusungunuka kumasiyanasiyana ndi mamasukidwe akayendedwe.Kutsika kwa viscosity, kusungunuka kwapamwamba komwe kumakhala nako.Mitundu yosiyanasiyana ya HPMC ndi yosiyana muzinthu zina ndipo kusungunuka kwawo m'madzi sikukhudzidwa ndi pH.
3) Kukula kwa tinthu: 100% kuchuluka kwa ma mesh 80.
4) Kachulukidwe kowoneka: 0.25-0.70 g/mL (nthawi zambiri pafupifupi 0.5 g/mL), kachulukidwe kake 1.26-1.31mL.
5) Kusintha kwamtundu kutentha: 190-200 ° C;Kutentha kwa carbonation: 280-300 ° C.
6) Kuvuta kwa pamwamba: 42-56 dyn / masentimita (2% yankho lamadzi).
7) Zomwe zili pamwamba pa methoxy mu HPMC, kutentha kwapansi kwa gelation, ndi kusungunuka kwapamwamba m'madzi ndi pamwamba.
8) HPMC ali ndi makhalidwe ena, mwachitsanzo, thickening katundu, pH bata, posungira madzi, kwambiri filimu kupanga katundu, bwino kumwazikana ndi adhesion luso.

Zogulitsa za Youngcel zimaphatikizapo mitundu yonse yazinthu zamadzimadzi monga zotsukira pansi, zotsukira ndi zotsukira mbale zokhala ndi pH pakati.6- 8
Achinyamatacelangagwiritsidwe ntchito ngati thickener kusintha rheology zotsukira madzi, kusintha maonekedwe ankafuna ndi kugwirizana kwabwino.
Achinyamatacel imathandizira mawonekedwe a viscous ndi zotsukira ma gel kukhala zothandiza komanso zabwino, chifukwaAchinyamatacelamalola zotsukira gel osakaniza kutsala pamwamba ndi kugwira ntchito kwa nthawi yaitali, kotero bwino kuyeretsa zotsatira.
- Kukhuthala zotsatira
- Kusintha kwa kusasinthasintha
- Kugwirizana ndi ma ionic surfactants
- Zothetsera zowonekera kwambiri
