Hydroxypropyl Methylcellulose (HPMC) mubikoresho byubwubatsi

Hydroxypropyl Methylcellulose (HPMC)ni ibice byinshi bikoreshwa cyane mubikorwa bitandukanye, bifite uruhare runini mubikorwa byubwubatsi. Iyi polymer ya syntetique ikomoka kuri selile isanga porogaramu zitabarika bitewe nimiterere yihariye, harimo kubika amazi, ubushobozi bwo kubyimba, hamwe nibintu bifatika. Mu rwego rwibikoresho byubwubatsi, HPMC ikora nk'inyongera ikomeye yongerera imikorere n'imikorere y'ibicuruzwa bitandukanye.

Gusobanukirwa HPMC:

HPMC, izwi kandi nka hypromellose, ni kimwe cya kabiri cyogukora, polymer-soluble polymer ikomoka kuri selile ikoresheje guhindura imiti. Synthesis ikubiyemo kuvura selile hamwe na okiside ya propylene na methyl chloride, biganisha ku gusimbuza amatsinda ya hydroxyl hamwe na hydroxypropyl na methyl. Ubu buryo butezimbere amazi yikomatanya kandi bugahindura imiterere yumubiri, bigatuma bukoreshwa muburyo butandukanye.

Ibyiza bya HPMC:

HPMC ifite imitungo myinshi ituma iba inyongera nziza mubikoresho byubwubatsi:

Kubika Amazi: HPMC yerekana ibintu byiza cyane byo gufata amazi, bigatuma iba ingirakamaro mubikoresho byubwubatsi nka minisiteri, imashini, na pompe. Ubushobozi bwayo bwo gukora imiterere isa na gel iyo ivanze namazi bifasha kwirinda gutakaza amazi byihuse mugihe cyo kuyakoresha no kuyakiza, bigatuma amazi meza yibikoresho bya sima.

Kubyimba: HPMC ikora nkibikoresho bikora neza, bitanga ubwiza bwibisubizo no kunoza imikorere. Uyu mutungo ufite akamaro kanini mugufata tile, guswera, hamwe nuruvange, aho byongera ubudahwema, koroshya kubishyira mubikorwa, hamwe nubushobozi bwo kwizirika hejuru yubutaka.

Imiterere ya firime: Iyo imaze gukama, HPMC ikora firime ibonerana kandi yoroheje, ikongerera igihe kirekire hamwe nikirere cyikirere cyimyenda hamwe na kashe. Ubu bushobozi bwo gukora firime ningirakamaro mukurinda ubuso bwinjira mubushuhe, imirasire ya UV, no kwangirika kwa mashini, bityo bikongerera igihe cyibikoresho byubwubatsi.

Kwizirika:HPMCKugira uruhare mu gufatira hamwe ibicuruzwa bitandukanye byubaka, byorohereza guhuza neza hagati yubutaka no kuzamura ubusugire bwimiterere muri rusange. Mu gufatisha amatafari no kuvanga ibintu, biteza imbere gukomera ku bice bitandukanye, birimo beto, ibiti, nubutaka.

Imiti ihamye: HPMC yerekana imiterere ihamye yimiti, igumana imiterere yayo murwego runini rwa pH nubushyuhe. Ikiranga cyemeza imikorere yigihe kirekire nigihe kirekire cyibikoresho byubwubatsi mubihe bitandukanye bidukikije.

Ikoreshwa rya HPMC mubikoresho byubwubatsi:

HPMC isanga ikoreshwa cyane mugutegura ibikoresho bitandukanye byubwubatsi, bigira uruhare mubikorwa byabo, kuramba, no gukora:

Mortars and Renders: HPMC ikunze kwinjizwa muri sima ishingiye kuri sima kandi igahindura kunoza imikorere, gufatira hamwe no gufata amazi. Mugukumira gutakaza amazi byihuse, itanga igihe kinini cyakazi kandi ikagabanya ibyago byo guturika no kugabanuka mugihe cyo gukira. Byongeye kandi, HPMC yongerera ubufatanye no guhora kwa minisiteri, itanga uburyo bumwe kandi ihuza neza na substrate.

Amashanyarazi ya Tile hamwe na Grout: Muri sisitemu yo gushiraho tile, HPMC ikora nkigice cyingenzi cyibikoresho byombi. Mu gufatira hamwe, itanga imitekerereze ya thixotropique, igafasha gukoresha byoroshye no guhindura amabati mugihe byemeza gukomera kubutaka. Muri grout, HPMC yongerera imiterere yimigezi, igabanya amahirwe yubusa kandi igateza imbere ubwiza bwa nyuma bwuburanga.

Amashanyarazi na Stuccos: HPMC igira uruhare runini mukuzamura imikorere yimbere yimbere ninyuma hamwe na stuccos. Mugutezimbere gufata amazi no gukora, byoroshya gukoresha neza, bigabanya gucika, kandi byongera imbaraga zubusabane hagati ya plaster na substrate. Byongeye kandi, HPMC ifasha kugenzura kugabanuka no kugabanuka, bikavamo kurangiza kimwe kandi biramba.

Sisitemu yo Kwirinda no Kurangiza Sisitemu (EIFS): EIFS yishingikiriza kuri HPMC yometse kuri HPMC hamwe na basecoats ku mbaho ​​zo kubika insimburangingo no gutanga umusozo wo kurinda hanze. HPMC ituma habaho ubushuhe bukwiye bw’imiterere, ikongerera imbaraga, kandi ikagira uruhare mu guhinduka no guhangana n’imyenda ya EIFS, bityo igateza imbere ubushyuhe n’imihindagurikire y’ikirere.

Inkongoro hamwe na kashe: HPMC ishingiye kuri kashe hamwe na kashe ikoreshwa cyane mubwubatsi kugirango yuzuze icyuho, ingingo, hamwe nibice muri substrate zitandukanye. Iyi mikorere yunguka kubika amazi ya HPMC, kuyifata, hamwe no gukora firime, bifasha gukora kashe ndende kandi idashobora guhangana nikirere, ikumira ubwinjira bwumwuka numwuka

kumeneka.

Ibicuruzwa bya Gypsumu: Mubikoresho byubwubatsi bishingiye kuri gypsumu nka plaster, ibivanze hamwe, hamwe no kwishyira hejuru, HPMC ikora nkumuhinduzi wa rheologiya hamwe nuwashinzwe gufata amazi. Itezimbere imikorere, igabanya kugabanuka, kandi ikongerera isano hagati ya gypsumu, bikavamo kurangiza neza no kugabanuka.

Hydroxypropyl Methylcellulose (HPMC)igira uruhare runini mubikorwa byubwubatsi, ikora nk'inyongera yibikorwa byinshi mubikoresho bitandukanye. Ihuza ryihariye ryimitungo, harimo kubika amazi, kubyimba, gufatira hamwe, no gukora firime, byongera imikorere, kuramba, hamwe nakazi k’ibikorwa byubwubatsi kuva kuri minisiteri no kubitanga kugeza kubifata hamwe na kashe. Mugihe urwego rwubwubatsi rukomeje gutera imbere, HPMC biteganijwe ko izakomeza kuba ikintu cyibanze, itera udushya no kuzamura ireme ryibidukikije byubatswe ku isi.
