Hydroxypropyl methylcellulose(HPMC) bụ ngwakọta nke a na-ejikarị eme ihe na ụlọ ọrụ dị iche iche, gụnyere ụlọ ọrụ ihe owuwu. Ngwongwo ya pụrụ iche na-eme ka ọ bụrụ ihe dị mkpa n'ọtụtụ ihe owuwu ihe owuwu. N'isiokwu a, anyị ga-enyocha ngwa nke hydroxypropyl methylcellulose na-arụ ọrụ na ụlọ ọrụ mmepụta ihe, na-akọwapụta mkpa na uru ya.
HPMC bụ apolymer soluble mmirisitere na cellulose. A na-enwetakarị ya dị ka ihe ngwọta hydroxypropyl methylcellulose, nke a na-ejikọta ya na mmiri ngwa ngwa iji mepụta ihe dị ka gel. Ihe ngwọta a na-arụ ọrụ dị ka ihe nkedo, thickener, na ihe nkiri bụbu na ngwa ihe owuwu.
Otu n'ime ihe ndị bụ isi eji hydroxypropyl methylcellulose eme ihe n'ụlọ ọrụ ihe owuwu bụ ka ngwa agha na plasta modifier. Mgbe agbakwunyere na ihe ndị sitere na ciment, HPMC na-eme ka ọrụ ha dịkwuo mma, ike nrapado, na ike ijide mmiri. Ọ na-arụ ọrụ dị ka ihe na-eme ka ọ dị arọ, na-ebelata ohere nke ịda mbà n'obi ma na-emeziwanye nkwekọ nke ngwakọta ahụ. Nke a na-eme ka ọ dịrị ndị na-arụ ọrụ ụlọ mfe itinye ngwa ngwa ma ọ bụ plasta nke ọma na nke ọma.
Ngwa ọzọ dị mkpa nkeHPMCna-ewu dị ka ihe mgbakwunye taịlị. Mgbe agbakwunyere na adhesives tile, HPMC na-eme ka ike nkekọ ha dịkwuo mma ma na-enye oge mepere emepe nke ọma, na-enye ohere maka mgbanwe dị mfe nke ntinye tile. Ọ na-emeziwanye ihe na-agbasa na wet nke nrapado, na-eme ka adhesion kwesịrị ekwesị na elu ala. Ọzọkwa, HPMC na-eme dị ka colloid na-echebe, na-egbochi ihicha nke nrapado na-akaghị aka ma na-ebelata nhazi nke cracks.
Na mgbakwunye na ngwa ngwa modifiers na tile adhesives, hydroxypropyl methylcellulose na-ejikwa n'ọtụtụ ebe dị ka ihe mgbakwunye onyinye na-eme ka onwe ya. A na-eji ogige ndị na-edozi onwe ha eme ihe iji nweta ihe dị mma na ọbụna n'elu tupu ntinye nke mkpuchi ala. A na-agbakwunye HPMC na ogige na-ebuli onwe ya ka ọ dịkwuo mma na-asọpụta na nhazi ọkwa ha. Ọ na-eme ka mmiri dị n'ime ahụ dịkwuo mma, na-enye ya ohere ịgbasa ngwa ngwa na ọkwa onwe ya, na-eme ka ọ dị mma, dị larịị.
Ọzọkwa,hydroxypropyl methylcellulosena-arụ ọrụ dị mkpa na nhazi nke mpụta mkpuchi na imecha sistemu (EIFS) na ụlọ ọrụ ihe owuwu. EIFS bụ sistemu nwere ọtụtụ ihe eji eme ihe mkpuchi ọkụ na ebumnuche ịchọ mma. A na-eji HPMC na akwa mkpuchi na imecha nke EIFS iji melite arụmọrụ ha, mgbape mgbawa, na nrapanye na mkpụrụ. Ọ na-eme ka mgbanwe na ịdịte aka nke mkpuchi ahụ dịkwuo mma, na-eme ka arụmọrụ dị ogologo.
N'ikpeazụ, hydroxypropyl methylcellulose nwere ọtụtụ ngwa na ụlọ ọrụ ihe owuwu. Ikike ya imegharị ngwa agha na plasta, kwalite nrapado tile, melite ogige na-edozi onwe ya, na iwusi EIFS ike na-eme ka ọ bụrụ ihe bara uru na ihe owuwu. Iji HPMC n'ime ngwa ndị a na-atụnye ụtụ n'ịrụ ọrụ ka mma, ịbawanye ike nkekọ, njirimara ọgwụgwọ ka mma, yana nkwalite ịdịte aka nke ọrụ owuwu. Ka ụlọ ọrụ ihe owuwu na-aga n'ihu na-etolite, ọrụ nke hydroxypropyl methylcellulose ga-anọgide na-adị mkpa, na-enye ngwọta maka nsogbu dị iche iche chere ihu na ọrụ owuwu.
