Amabuye ya minisiteri yo hanze no kurangiza (EIFS) afite uruhare runini mugutanga ubwishingizi, kwirinda ikirere hamwe nuburanga bwiza. Hydroxypropyl methylcellulose (HPMC) ninyongera ikoreshwa muri minisiteri ya EIFS bitewe nuburyo bwinshi, kubika amazi nubushobozi bwo kunoza imikorere.
1. Intangiriro kuri EIFS mortar:
EIFS mortar ni ibikoresho byinshi bikoreshwa mugukingira no kurangiza sisitemu yo hanze.
Ubusanzwe igizwe na sima ihuza, igiteranyo, fibre, inyongeramusaruro namazi.
EIFS mortar irashobora gukoreshwa nka primer muguhuza panneur insulasiyo nkikoti yo hejuru kugirango yongere ubwiza bwikirere ndetse n’ikirere.
2.Hydroxypropylmethylcellulose (HPMC):
HPMC ni selile ya selile ikomoka kuri polymer naturel selile.
Ikoreshwa cyane mubikoresho byo kubaka amazi yo kubika amazi, kubyimba no kongera imbaraga.
Muri minisiteri ya EIFS, HPMC ikora nka moderi ihindura imvugo, itezimbere, guhuza hamwe no kurwanya sag.
3. Ibikoresho bya formula:
a. Bima ishingiye kuri sima:
Portland Cement: Itanga imbaraga no gukomera.
Isima ivanze (urugero: Portland limestone cement): Yongera igihe kirekire kandi igabanya ikirenge cya karubone.
b. Igiterane:
Umusenyi: Ingano nuburyo bwiza.
Igiteranyo cyoroheje (urugero rwagutse perlite): Kunoza imiterere yumuriro.
C. fibre:
Fiberglass irwanya Alkali: Yongera imbaraga zingana no guhangana.
d. Inyongera:
HPMC: kubika amazi, gukora, no kurwanya sag.
Umukozi winjiza ikirere: Kunoza ubukonje bukabije.
Retarder: Igenzura gushiraho igihe mubihe bishyushye.
Guhindura Polymer: Kongera guhinduka no kuramba.
e. Amazi: Ibyingenzi mumazi no gukora.
4. Ibiranga HPMC muri minisiteri ya EIFS:
a. Kubika Amazi: HPMC ikurura kandi ikagumana amazi, igatanga amazi maremare kandi igateza imbere imikorere.
b. Imikorere: HPMC itanga minisiteri yoroheje kandi ihamye, byoroshye kubaka.
C. Kurwanya-sag: HPMC ifasha kurinda minisiteri kugabanuka cyangwa gutembera hejuru yubutumburuke, byemeza ubunini bumwe.
d. Adhesion: HPMC yongerera imbaraga hagati ya minisiteri na substrate, igateza imbere igihe kirekire kandi ikaramba.
e. Kurwanya Crack: HPMC itezimbere guhinduka no guhuza imbaraga za minisiteri kandi bigabanya ibyago byo guturika.
5. Uburyo bwo kuvanga:
a. Uburyo mbere yo gutose:
Banza utose HPMC mubikoresho bisukuye hamwe hafi 70-80% y'amazi yose avanze.
Kuvanga neza ibikoresho byumye (sima, igiteranyo, fibre) mukuvanga.
Buhoro buhoro ongeraho igisubizo cya HPMC cyateganijwe mugihe ukurura kugeza igihe ibyifuzo bigeze.
Hindura ibirimo amazi nkuko bikenewe kugirango ugere kubikorwa byifuzwa.
b. Uburyo bwo kuvanga bwumye:
Kuma kuvanga HPMC nibikoresho byumye (sima, igiteranyo, fibre) mukuvanga.
Buhoro buhoro ongeramo amazi mugihe ukurura kugeza igihe ibyifuzo bigeze.
Kuvanga neza kugirango urebe no gukwirakwiza HPMC nibindi bikoresho.
C. Kwipimisha guhuza: Kwipimisha guhuza hamwe na HPMC nibindi byongeweho kugirango habeho imikoranire myiza nibikorwa.
6. Ikoreshwa rya tekinoroji:
a. Gutegura Substrate: Menya neza ko substrate isukuye, yumye kandi idafite umwanda.
b. Porogaramu y'ibanze:
Koresha EIFS Mortar Primer kuri substrate ukoresheje trowel cyangwa ibikoresho bya spray.
Menya neza ko ubunini buringaniye kandi ubwishingizi ni bwiza, cyane cyane hafi yimpande.
Shyiramo ikibaho cyiziritse muri minisiteri itose kandi utange umwanya uhagije wo gukira.
C. Ikoti risaba:
Koresha ikoti rya EIFS minisiteri hejuru ya primer yakize ukoresheje trowel cyangwa ibikoresho byo gutera.
Imyambarire cyangwa kurangiza hejuru nkuko ubyifuza, witondera kugera kuburinganire n'ubwiza.
Kiza ikoti hejuru ukurikije ibyifuzo byabayikoze kugirango uyirinde ikirere kibi.
7. Kugenzura ubuziranenge no kugerageza:
a. Guhuzagurika: Kurikirana ubudahangarwa bwa minisiteri mugihe cyose cyo kuvanga no gusaba kugirango ubone uburinganire.
b. Adhesion: Igeragezwa rya Adhesion rikorwa kugirango harebwe imbaraga zubusabane hagati ya minisiteri na substrate.
C. Imikorere: Suzuma imikorere ikoresheje ibizamini bidahwitse no kwitegereza mugihe cyo kubaka.
d. Kuramba: Kora ibizamini biramba, harimo kuzenguruka-gukonjesha no kwirinda amazi, kugirango usuzume imikorere yigihe kirekire.
Gukoresha HPMC mugutegura EIFS minisiteri itanga ibyiza byinshi mubijyanye no gukora, gufatana, kurwanya sag no kuramba. Mugusobanukirwa imiterere ya HPMC no gukurikiza uburyo bukwiye bwo kuvanga no gukoresha tekiniki, abashoramari barashobora kugera kubikorwa byiza bya EIFS byujuje ubuziranenge kandi byongera ubwubatsi bwiza no kuramba.
