Hydroxypropyl methylcellulose (HPMC) ni selile yahinduwe ya selile ikoreshwa cyane mubikorwa byubwubatsi kubintu byiza byayo.
1. Incamake yimikorere yibanze
HPMC ni uburozi butagira ubumara, butagira impumuro nziza, selile nonionic selulose ether ifite amazi meza kandi akomera. Ibintu nyamukuru byingenzi birimo:
Kubyimba: Irashobora kongera cyane ubwiza bwigisubizo kandi igatezimbere imiterere yimiterere yibikoresho byubaka.
Kubika amazi: Ifite ubushobozi bwiza bwo gufata amazi kandi irashobora kugabanya gutakaza amazi.
Adhesion: Kongera imbaraga hagati yibikoresho byubaka na substrate.
Amavuta: Kunoza neza no koroshya imikorere mugihe cyo kubaka.
Kurwanya ikirere: imikorere ihamye mugihe cy'ubushyuhe bwo hejuru cyangwa buke.
2. Porogaramu zihariye mubikorwa byubwubatsi
2.1. Isima ya sima
Muri sima ya sima, HPMC ikoreshwa cyane nkigikoresho cyo kubika amazi no kubyimba. Irashobora gukumira neza minisiteri kumeneka no gutakaza imbaraga kubera guhumeka vuba kwamazi, kandi mugihe kimwe no kunoza imikorere yubwubatsi nubushobozi bwo kurwanya kugabanuka. Mortar hamwe no gufata amazi akomeye birakwiriye cyane cyane kubakwa mubushyuhe bwinshi nubushuhe buke.
2.2. Amatafari
Gufata amatafari bisaba imbaraga zihuza kandi byoroshye kubaka, kandi HPMC igira uruhare runini muribi. Ku ruhande rumwe, itezimbere ingaruka zifatika binyuze mubyimbye no kubika amazi; kurundi ruhande, byongerera igihe cyo gufungura kugirango byorohereze abakozi guhindura cile cile cile kumwanya muremure.
2.3. Ifu yuzuye
Nkibikoresho byo kuringaniza urukuta, imikorere yubwubatsi nibicuruzwa byarangiye byifu ya putty bifitanye isano rya bugufi nuruhare rwa HPMC. HPMC irashobora kunoza ubworoherane no kugumana amazi yifu ya putty, ikarinda urukuta no kumenagura ifu, kandi igateza imbere kuramba hamwe nuburanga bwibicuruzwa byarangiye.
2.4. Ibicuruzwa bishingiye kuri gypsumu
Muri gypsumu ishingiye ku kuringaniza no kuringaniza gypsumu, HPMC itanga uburyo bwiza bwo kubyimba no gufata amazi, igateza imbere kugabanuka no gukora neza kubicuruzwa bya gypsumu, kandi ikirinda kumeneka n'imbaraga zidahagije ziterwa no gutakaza amazi menshi.
2.5. Amashanyarazi
HPMC irashobora gukoreshwa nkibyimbye hamwe na stabilisateur kubitwikiriye amazi, bigatanga igifuniko cyiza cya rheologiya hamwe nuburyo bwo gukora firime kugirango harebwe uburinganire no gufatana.
2.6. Shira plaster hanyuma utere minisiteri
Mu gutera imashini, HPMC itanga amazi meza no kuvoma neza, mugihe igabanya ibintu bya sag na delamination, bizamura imikorere nubwiza bwubwubatsi.
2.7. Sisitemu yo gukingira hanze
Muri sisitemu yo kubika urukuta hanze, kubika amazi hamwe no kurwanya kunyerera bya HPMC bigira uruhare runini muguhuza no guhomeka minisiteri. Irashobora kunoza imikorere yubwubatsi bwa minisiteri kandi ikemeza ko ihamye kandi irambye ya sisitemu yo kubika.
3. Ibyiza bya HPMC mubikorwa byubwubatsi
Kunoza imikorere yubwubatsi: Kwiyongera kwa HPMC bituma ibikoresho byubwubatsi bikora neza, inzira yubwubatsi iroroshye, kandi imyanda yibikoresho ningorane zo kubaka ziragabanuka.
Mugabanye ibibazo byubuziranenge: Nyuma yo gufata amazi no kuyifata neza, ibikoresho bizagira ibibazo bike nko guturika no gusiba, kuzamura ubwiza bwibicuruzwa byarangiye.
Kuzigama ingufu no kurengera ibidukikije: Ubushobozi buhanitse bwa HPMC butunganya imikorere yibintu, bugabanya imyanda iterwa nubwubatsi bwongeye, kandi bigira ingaruka nziza mukuzigama ingufu no kurengera ibidukikije.
Kugenzura ibiciro: Mugutezimbere imikorere yibikoresho, ikiguzi cyo kubungabunga no gusimburwa nyuma kiragabanuka, bigatuma ubukungu bwiyongera cyane.
4. Iterambere ry'ejo hazaza
Mugihe inganda zubwubatsi zikeneye ibikoresho byangiza kandi byangiza ibidukikije byiyongera, ubushobozi bwa HPMC muguhindura no kubishyira hamwe buracyashakishwa. Kurugero, guhuza HPMC nubundi buryo bwo guhindura imiti kugirango utezimbere uburyo bwihariye bwo gukoresha ibintu bitandukanye ni icyerekezo cyingenzi cyiterambere. Byongeye kandi, kurushaho kunoza imikorere ihamye no gukora neza binyuze muburyo bwo gukora neza nabyo byibandwaho mubushakashatsi bwinganda.
Hydroxypropyl methylcellulose igira uruhare runini mubikorwa byubwubatsi kubera ibyiza byayo. Kuva kuri sima ya sima kugeza kumatafari, kuva ifu yuzuye kugeza kumazi adafite amazi, ikoreshwa rya HPMC rikubiyemo ibintu byose byubaka. Mu bihe biri imbere, hamwe n’iterambere ry’ikoranabuhanga no gushyira mu bikorwa byimbitse, HPMC izagira uruhare runini mu gufasha inganda z’ubwubatsi kugera ku bikorwa byiza, gukoresha ingufu nke ndetse n’intego zo kurengera ibidukikije.
