Hydroxypropylmethylcellulose (HPMC) ni uruganda rukoreshwa cyane mubikorwa byubwubatsi. Igikorwa cyacyo nyamukuru nukuzamura imikorere yibikoresho nka minisiteri na beto. Bumwe mu buryo bwa HPMC ni gypsumu ishingiye ku kwishyira hamwe, yagize ingaruka zikomeye mu bwubatsi.
Kwiyoroshya-plaster ni ibikoresho byo mu rwego rwohejuru byoroshye gushyiramo kandi birashobora gukoreshwa hejuru ya beto cyangwa ishaje. Nihitamo ryamamare ryubucuruzi nuburaro kubera imikorere yaryo ndende kandi iramba. Ikibazo nyamukuru muburyo bwo kwishyiriraho plaster ni ugukomeza ubuziranenge no guhuza ibikoresho mugihe cyo gutegura no kwishyiriraho. Aha niho HPMC ikinira.
Hydroxypropyl methylcellulose ni umubyimba wubukorikori wongewe kuri gypsumu ishingiye ku kwivanga kugirango wizere no gukwirakwiza imvange. Ifasha kandi kugenzura ubwiza no gukomeza ubwiza bwibikoresho. HPMC nikintu cyingenzi muburyo bwo kuringaniza gypsumu yivanga kuko ihindura imvange, ikemeza ko amacakubiri atabaho kandi atezimbere imbaraga zo guhuza imvange.
Igikorwa cyo kwishyiriraho gypsumu kirimo kuvanga gypsumu na HPMC namazi. Amazi akora nk'itwara rya HPMC, yemeza ko ikwirakwizwa no kuvanga. HPMC yongewe kuvanga ku gipimo cya 1-5% yuburemere bwumye bwa gypsumu, bitewe nubushake bwifuzwa no gukoresha amaherezo yibikoresho.
Hariho inyungu nyinshi zo kongeramo HPMC murwego rwo kwishyiriraho plaster. Yongera ibikoresho biramba byongera imbaraga no kurwanya amazi, imiti no gukuramo. Byongeye kandi, HPMC yongerera ubworoherane bwibikoresho, ikabemerera guhuza nimpinduka zubushyuhe nubushuhe. Ibi birinda gucikamo, kugabanya imyanda no kongera ubwiza bwamagorofa yawe.
Hydroxypropyl methylcellulose irashobora kandi gukora nka poroteri ya adhesion yongerera imbaraga imbaraga za gypsum yo kwipimisha kuri substrate. Iyo imvange ikoreshejwe, HPMC yemeza ko imvange yumira kuri substrate, igakora umurunga uhoraho kandi ukomeye. Ibi bivanaho gukenera imashini, kubika umwanya namafaranga mugihe cyo kwishyiriraho.
Iyindi nyungu ya HPMC muri gypsumu ishingiye ku kwishyira hamwe ni uruhare rwayo mu kubungabunga ibidukikije mu nganda zubaka. HPMC yangiza ibidukikije kandi yoroshye kuyijugunya, ikagira ubundi buryo bwizewe kandi burambye kubindi bikoresho byimiti.
Hydroxypropyl methylcellulose (HPMC) yerekanye ko ari ikintu cyingenzi muri gypsumu ishingiye ku kwishyira hamwe. Mugutanga umusanzu muburyo buhoraho, ubwiza nuburinganire bwuruvange, HPMC itezimbere kuramba hamwe nuburanga bwibikoresho. Inyungu zayo zongerewe imbaraga zingirakamaro zifasha kuzigama igihe n'amafaranga. Byongeye kandi, imikoreshereze ya HPMC iteza imbere ibidukikije, bigatuma ihitamo neza mubikorwa byubwubatsi.
