Hydroxypropyl MethylCellulose (HPMC)
CAS: 9004-65-3
Hydroxypropyl MethylCellulose (HPMC) ankagwiritsa ntchito yomanga, mankhwala, chakudya, zodzikongoletsera, detergent, utoto, monga thickener, emulsifier, filimu-kale, binder, zimasweka wothandizira, colloids.We zoteteza angapereke kalasi zonse HPMC, nafenso tikhoza kupereka kusinthidwa HPMC malingana ndi zofuna za makasitomala. Pambuyo kusinthidwa ndi mankhwala pamwamba, ife tikhoza kutenga katundu amene anabalalitsidwa mu madzi msanga, kutalikitsa nthawi lotseguka, odana ndi sagging, etc.

Chitsanzo Mapulogalamu a HPMC:
matailosi Mwaluso
● Good madzi posungira: yaitali kutsegula nthawi kupanga chindwi zosavuta.
● Kukweza guluu wolimba ndi kutsetsereka kukana: makamaka matailosi lolemera.
● Bwino workability: lubricity ndi plasticity a pulasitala anaonetsetsa, matope ingagwiritsidwe ntchito mosavuta ndi nsanga.
Simenti pulasitala / kuuma mix matope
● Easy youma mix chilinganizo chifukwa madzi ozizira solubility: chotupa mapangidwe zikhoza kupewedwa, abwino kwa matailosi lolemera.
● Good madzi posungira: kupewa imfa madzimadzi kuti magawo a, yoyenera zili madzi akukhala osakaniza limene linapatsa concreting nthawi yaitali.
● kuwonjezeka madzi: kuchuluka nthawi lotseguka, kukodzedwa spry m'dera ndi chiphunzitso kwambiri ndalama.
● Zosavutirako kufalitsa ndi bwino sagging kukana chifukwa bwino kugwirizana.
Wall putty
● Water posungira: maximized madzi zili mu slurry.
● Anti-sagging: pamene kufalitsa thicker odula corrugation zikhoza kupewedwa.
● Kuchuluka matope zokolola: malingana ndi kulemera kwa osakaniza youma ndi chiphunzitso yoyenera, HPMC angadwale matope buku.
Kunja zotetezera kutentha ndi kutsiriza System (EIFS)
● Kukweza guluu wolimba kwambiri.
● Good wetting mphamvu kwa EPS bolodi ndi gawo lapansi.
● achepetsedwa mpweya entrancement ndi madzi kutengedwa.
Self-kukhazikika
● Chitetezo exudation madzi ndi zinthu sedimentation.
● No zotsatira pa slurry fluidity ndi kukhuthala otsika
HPMC, pamene tingachidziwe madzi posungira bwino kumaliza ntchito padziko.
mng'alu filler
● Bwino workability: yoyenera makulidwe ndi plasticity.
● Water posungira zipangitsa yaitali ntchito nthawi.
● sag kukana: bwino matope kulumikiza mphamvu.
