Enwere ọtụtụ ihe na-emetụta ntinye nke hydroxypropyl methylcellulose HPMC n'ime ihe owuwu ụlọ, karịsịa plasta nke dabeere na gypsum, dị ka ndị a:
1 njide mmiri
Hydroxypropyl methylcellulose maka owuwu na-egbochi mmịnye oke mmiri site na mkpụrụ, na mgbe edobere gypsum kpamkpam, a ga-edobe mmiri na plasta dị ka o kwere mee. A na-akpọ njirimara a njide mmiri na ọ dabara kpọmkwem na viscosity nke ngwọta hydroxypropyl methylcellulose na-ewu na stucco. Ihe dị elu nke viscosity nke ngwọta, otú ahụ ka ikike njigide mmiri ya dị elu. Ozugbo ọdịnaya mmiri na-abawanye, ikike ijide mmiri ga-ebelata. Nke a bụ n'ihi na ụbara mmiri na-eme ka ihe ngwọta nke hydroxypropyl methylcellulose na-arụ ọrụ, na-ebute mbelata nke viscosity.
2 mgbochi sagging
Ihe nkedo nwere ihe mgbochi sag na-enye ndị na-achọ ihe ohere itinye akwa mkpuchi buru ibu na-enweghị sagging, ma pụtakwara na plasta n'onwe ya abụghị thixotropic, nke ga-adaba ala n'oge ngwa.
3 Belata viscosity, ihe owuwu dị mfe
Enwere ike nweta plasta gypsum dị ala na nke dị mfe ịrụ site na ịgbakwunye ngwaahịa hydroxypropyl methylcellulose dị iche iche nke ụlọ. Mgbe ị na-eji akara ngosi viscosity dị ala nke hydroxypropyl methylcellulose nke ụlọ, ọkwa nke viscosity dị ntakịrị belata Ihe owuwu ahụ na-adị mfe, mana ikike njigide mmiri nke obere viscosity hydroxypropyl methylcellulose na-adịghị ike, na mgbakwunye ego kwesịrị ịbawanye.
4 Ndakọrịta nke stucco
Maka ọnụ ọgụgụ a na-akwụ ụgwọ nke ụrọ akọrọ, ọ na-akawanye mma iji mepụta ụda mmiri mmiri dị elu, nke a ga-enweta site n'ịgbakwunye mmiri na ikuku ikuku. Mana oke mmiri na afụ ikuku dị oke
