HydroxyPropyl MethylcellALese (HPMC) ni selile itari ionic yakoreshejwe cyane mubikoresho byubaka, cyane cyane minisiteri na plaster. Nka kongeramo, HPMC irashobora kunoza uburyo bunyuranye nibi bikoresho, harimo ibikorwa, kugumana amazi, ibihano, nibindi.
1. Imiterere yimiti n'imiterere ya HPMC
HPMC ni polymer-synthemed polymer yabonetse muguhindura amatsinda ya hydroxyl ya selile ya selile binyuze mubururu na hydroxy opropypylepy. Igice cyacyo cyibanze ni glucose, gihujwe na β-1,4-glycosic. Urunigi rurerure rwa selile rutanga imiterere myiza ya firime hamwe nibikorwa bifatika, mugihe intangiriro ya methyl na hydroxyPropyl n'amatsinda ya hydroxyPropyle atezimbere umukecuru no gutuza.
Imiterere yimiti ya HPMC itanga ibiranga bikurikira:
Amazi yoroheje: Irashobora gusesa vuba mumazi akonje kugirango akore neza amazi.
Guhindura visosity: Igisubizo cya HPMC gifite ubushyuhe bworoshye, buterwa nuburemere bwayo no kwibanda.
Guhagarara: Birahamye acide na shingiro kandi birashobora kugumana imikorere yayo hejuru ya ph.
2. Uburyo bwa HPMC bwo kuzamura imikorere ya minisiteri na plaster
(2.1). Gutezimbere
Kugumana amazi bivuga ubushobozi bwa minisiteri cyangwa plaster kugirango bagumane amazi, aribyingenzi muri sima hydetion hamwe nuburyo bukomeye. HPMC itezimbere kugumana amazi binyuze muburyo bukurikira:
Ingaruka ya Filime: HPMC ikora firime yoroheje muri minisiteri cyangwa plaster, igabanye igiciro cyamazi.
MoleCueld Amazi Yinjira: Molekile ya HPMC irashobora gukurura amazi menshi, kugabanya igihombo cyamazi mugihe cyo kubaka.
Harafunzwe n'amazi menshi afasha kwibeshya byimazeyo, bityo bigatuma imbaraga n'ibiranga minisiteri na plaster. Byongeye kandi, bigabanya kandi gushiraho ibice biterwa no gutakaza amazi menshi.
(2.2). Kunoza ibikorwa
Igikorwa bivuga imikorere yimikorere ya minisiteri na plaster mugihe cyubwubatsi, nkamateka nubushobozi. Uburyo bwa HPMC itezimbere ibikorwa birimo:
Kunoza Plastike: HPMC itanga amavuta meza, gutanga imvange nziza ya plastique n'amasuka.
Kwirinda gucika no gutandukanya: Ingaruka zijimye za HPMC zifasha gukomeza no gukwirakwiza ibice, gukumira umutinzi cyangwa gutandukana muri mirtar cyangwa plaster.
Ibi bituma lirtar cyangwa plaster yoroshye gukorana mugihe cyo kubaka, kwemerera byinshi no gushyira mubikorwa no guhinduranya, kugabanya amahirwe yo guta no kugende.
(2.3). Kwiyongera Kurwanya Crack
Mortar na Plaster barashobora gucika kubera umuvuduko mwinshi mugihe gikomeye, kandi HPMC ifasha kugabanya iyi ngingo:
Guhinduka: Imiterere yimiterere yakozwe na HPMC mubikoresho byongera guhinduka kwa minisiteri na plaster, bityo bikurura no kugabanya imihangayiko.
Kumamake kumeneka: Kuberako HPMC itanga ihohoterwa ryiza, amazi arashobora kurekurwa cyane, kugabanya impinduka zubunini mugihe cyumye.
Iyi mitungo igabanya amahirwe yo gucengera no kunoza iherezo ryibikoresho.
3. Ingero za porogaramu ya HPMC muri MISTAR NA POSS
(3.1). Tile
Muri Tile avunika, HPMC itanga imikoreshereze myiza y'amazi no kurwanya kunyerera, kwemerera amabati gukurikiza substrate kandi ukomeze gutangaza neza.
(3.2). Mristar
Kwishyira hamwe kwa minisiteri bisaba amazi menshi nubwitonzi. Ubushobozi bwo kugumana amazi menshi hamwe nubushobozi bwo guhindura visositine bufasha kugera kuri ibi bisabwa, bikavamo ubuso bwiza.
(3.3). Plaster
HPMC yongerera ibirango no gutesha agaciro Plaster, cyane cyane mu rukuta rw'inyuma plastersing, kandi irashobora kunanira gukandagira no kugwa biterwa n'ibintu bitandukanye by'ibidukikije.
4. Ingamba zo gukoresha HPMC
(4.1). Imikoreshereze
Umubare wa HPMC ukoreshwa muri minisiteri na plaster mubisanzwe ni amafaranga make mubijyanye nuburemere bwibiro, nka 0.1% kuri 0.5%. Byinshi Hpmc bizavamo vicosi ikabije kandi bigira ingaruka ku gikorwa; Ntabwo cyane bizagora neza imikorere.
(4.2). Guhuza nabandi banyongera
Iyo ukoresheje HPMC, birakenewe gusuzuma guhuza nibindi binjira imiti (nko kugabanya amazi, abakozi bashinzwe ikirere, nibindi) kugirango barebe ko nta bikoresho byanyuma bibaho cyangwa imikorere yanyuma yibikoresho bigira ingaruka.
Nkibintu byingenzi byimiti, ikoreshwa rya HPMC muri minisiteri kandi itezimbere cyane ko kugumana amazi, gukora ibikorwa no kurwanya. Izi nyungu ntabwo zongeza ingaruka zubwubatsi no gutangaza ibintu, ariko nanone byiteze imbere kuramba no kwiringirwa k'umushinga. Mubyiciro byihariye, nukugira umwambaro kandi ushireho HPMC, imikorere ya minisiteri na plaster irashobora kugorana.
