Ikoreshwa ryingenzi rya hydroxypropyl methylcellulose HPMC mubikoresho byubaka:
1. plaque ishingiye kuri sima
⑴ Kunoza uburinganire, koroshya guhomesha byoroshye gukurura, kunoza imishahara, kongera amazi no kuvoma, no kunoza imikorere.
Gufata amazi menshi, kongera igihe cyo kubika minisiteri, kunoza imikorere, no korohereza hydrata no gukomera kwa minisiteri kugirango bitange imbaraga nyinshi zubukanishi.
⑶ Kugenzura itangizwa ryumwuka kugirango ukureho ibice hejuru yubuso kandi bigire ubuso bwiza.
2. Gypsumu ishingiye kuri plaster nibicuruzwa bya gypsumu
⑴ Kunoza uburinganire, koroshya guhomesha byoroshye gukurura, kunoza imishahara, kongera amazi no kuvoma, no kunoza imikorere.
Gufata amazi menshi, kongera igihe cyo kubika minisiteri, kunoza imikorere, no korohereza hydrata no gukomera kwa minisiteri kugirango bitange imbaraga nyinshi zubukanishi.
⑶ Kugenzura uburinganire bwa minisiteri kugirango ubeho neza.
3. Masonry Mortar
⑴ Kongera imbaraga hamwe nubuso bwububiko, kongera amazi, no kunoza imbaraga za minisiteri.
Kunoza amavuta na plastike, no kunoza ubwubatsi;minisiteri yatunganijwe na selulose ether iroroshye kubaka, ikiza igihe cyo kubaka kandi igabanya ibiciro byubwubatsi.
⑶ Amazi maremare agumana selile ya selile, ikwiranye n'amatafari akurura amazi menshi.
4. Umwanya wuzuye wuzuza
Kubika amazi meza, ongera igihe cyo gufungura no kunoza imikorere.Amavuta menshi, byoroshye kuvanga.⑵ Kunoza kugabanuka kugabanuka no guhangana, kunoza ubwiza bwubutaka.Kunoza gufatana hejuru yubusabane no gutanga neza kandi neza.
5. Amatafari ya Tile ⑴Byoroshye kumisha ibikoresho bivanze, nta bisebe, kongera umuvuduko wo gusaba, kunoza imikorere yubwubatsi, kuzigama igihe cyakazi no kugabanya amafaranga yakazi.⑵ Mugukomeza igihe cyo gufungura, imikorere ya tiling irashobora kunozwa kandi ingaruka nziza yo gufatira hamwe irashobora gutangwa.
6. Kwiyoroshya ibikoresho byo hasi ⑴ bitanga ubwiza kandi birashobora gukoreshwa nkinyongeramusaruro.Kuzamura ubushobozi bwamazi no kunoza imikorere yo gutunganya ubutaka.⑶ Kugenzura gufata amazi no kugabanuka, kugabanya ibice no kugabanuka kwubutaka.
7. Irangi rishingiye kumazi ⑴Kwirinda imvura igwa kandi wongere ubuzima bwibicuruzwa.Ihindagurika ryibinyabuzima ryinshi, guhuza neza nibindi bice.Gutezimbere amazi, gutanga ibyiza birwanya anti-flash, anti-sagging hamwe no kuringaniza ibintu, kandi urebe neza ko birangiye neza.
8. Ifu ya Wallpaper ⑴ Gushonga vuba nta kubyimba, nibyiza kuvanga.⑵ gutanga imbaraga zingana.
9. Ikibaho cya sima cyakuweho (1) gifite ubwuzuzanye nubwinshi, kandi byongera ubushobozi bwibicuruzwa biva hanze.Kunoza imbaraga zicyatsi, guteza imbere hydrated ningaruka zo gukiza, no kongera umusaruro.
10 , na Crack zatewe no gukama kugabanuka.HPMC nayo ifite ingaruka zimwe zo kwinjiza ikirere.Igicuruzwa cya HPMC gikoreshwa cyane cyane kuri minisiteri yiteguye kuvangwa gifite urugero rwinshi rwumuyaga uhumeka, umwe kandi muto wo mu kirere, bishobora kuzamura imbaraga no koroshya imyanda ivanze.Igicuruzwa cya HPMC gikoreshwa cyane cyane kubutaka buvanze na minisiteri bifite ingaruka zimwe zo kudindiza, bishobora kongera igihe cyo gufungura minisiteri ivanze kandi bikagabanya ingorane zo kubaka.
