HPMC (Hydroxypropyl Methyl Cellulose) na HEMC (Hydroxy Ethyl Methyl Cellulose) ni ether za cellulose zikunze gukoreshwa mu bikoresho by'ubwubatsi bitewe n'imiterere yazo yihariye. Ni polymeri zishobora gushonga mu mazi zikomoka kuri cellulose, polymeri karemano iboneka mu nkuta z'uturemangingo tw'ibimera. HPMC na HEMC bikoreshwa nk'inyongera mu bikoresho bitandukanye by'ubwubatsi kugira ngo byongere imiterere yabyo kandi binoze uburyo bwo kuyitunganya.
Izi zikurikira ni zimwe mu ngero za HPMC na HEMC mu bikoresho by'ubwubatsi:
Udukoresho two gufatanya mu matiles: HPMC na HEMC bikunze kongerwa kuri kole zo gufatanya mu matiles kugira ngo byongere ubushobozi bwo gukora no gukomera. Izi polima zikora nk'izikomeza imbaraga, zigatanga igihe cyiza cyo gufungura (igihe kole iguma ikoreshwa) kandi zikagabanya kugwa kw'amatiles. Binongera kandi uburyo kole ifatana n'ibintu bitandukanye.
Imashini zikoreshwa mu gusimbuza: HPMC na HEMC bikoreshwa mu bikoresho bikoreshwa mu gusimbuza nk'imashini zikoreshwa mu gusimbuza, gusimbuza no mu buryo bwo kurangiza ubushyuhe bwo hanze (EIFS). Izi polymer zinoza ubushobozi bwo gukora bwa sima, bigatuma byoroha kuyikwirakwiza no kuyikoresha. Zinongera kandi guhuza, zigabanya amazi anyurwa kandi zigatuma sima ifatana n'ibintu bitandukanye.
Ibikoresho bishingiye kuri Gypsum: HPMC na HEMC bikoreshwa mu bikoresho bishingiye kuri Gypsum nka plaster za Gypsum, imvange z’ingingo n’ibice byo munsi byigenga. Bikora nk'ibintu bibungabunga amazi, binongera ubushobozi bwo gukora no kongera igihe cyo gushyiraho ibikoresho. Izi polymeri kandi zongerera imbaraga ubudahangarwa bw'imivuniko, zigabanya gucikagurika no kunoza gufatana.
Ibinyabutabire byigenga: HPMC na HEMC byongerwa ku binyabutabire byigenga kugira ngo binoze imiterere y'amazi n'uburyo anyuramo. Izi polima zifasha kugabanya ubukana, kugenzura uburyo amazi yinjira kandi zigatanga imiterere myiza y'ubuso. Binongera kandi uburyo ibinyabutabire byifatanya n'ubutaka.
Guhuza: HPMC na HEMC bishobora gukoreshwa mu guhuza amatafari n'amabuye. Bikora nk'ibikoresho bihindura imiterere y'amaraso, binoza uburyo amazi agenda n'ubushobozi bwo gukora. Izi polima kandi zigabanya kwinjira kw'amazi, zinoza gufatana no kongera ubushobozi bwo kudafatana kw'amazi.
Muri rusange, HPMC na HEMC bikoreshwa cyane mu bikoresho by'ubwubatsi bitewe n'ubushobozi bwabyo bwo kunoza uburyo bwo gutunganya, gufatana, kubika amazi, no gukora neza kw'ibicuruzwa muri rusange. Biteza imbere uburyo bwiza bwo kubaka binyuze mu kunoza kuramba no kugira ireme ry'ibikoresho bitandukanye by'ubwubatsi.
