Hydroxypropyl methylcellulose (HPMC) ni polymer ivanze ikoreshwa mubikoresho byubwubatsi, cyane cyane muri gypsumu ireba plaster, aho igira uruhare runini. Nka nyongera, HPMC irashobora kunoza neza imikorere yakazi, gufata amazi no gufatira gypsumu ireba plaster, bityo ikoreshwa cyane mubwubatsi no gushushanya.
1. Ibiranga shingiro bya HPMC
HPMC ni selile itari ionic selulose ether ifite amazi meza yo gukomera no kubyimba. Irashobora gushonga vuba mumazi kugirango ikore amazi amwe ya colloidal, kandi ifatanye neza, amavuta, gukora firime no kubika amazi. Ibiranga bituma HPMC ikoreshwa cyane mubikoresho byubwubatsi, cyane cyane ikwiriye gukoreshwa mubikoresho bishingiye kuri gypsumu.
Ibintu nyamukuru biranga HPMC harimo ibintu bikurikira:
Kubika amazi: HPMC irashobora kugumana neza ubuhehere muri gypsumu ireba plaster, bityo ikongerera igihe cyo gufungura nigihe cyo gukora cyibikoresho.
Kubyimba: Nkibyimbye, HPMC irashobora kongera ububobere bwa plasta, ikarinda kugabanuka, kandi ikanonosora ububobere.
Amavuta yo kwisiga: Amavuta yo kwisiga ya HPMC atezimbere uburyo bwo gufata neza plaster kandi byoroshe kubaka.
Umutungo ukora firime: Irashobora gukora firime ikingira hejuru ya plaster, igateza imbere guhangana na plaster.
2. Uburyo bwibikorwa bya HPMC muri gypsumu ireba plaster
Nyuma yo kongeramo HPMC kuri gypsum ireba plaster, ibintu bifatika byanozwa cyane cyane mubice bikurikira:
Kunoza gufata neza amazi: Mugihe cyubwubatsi bwa gypsumu ireba plaster, niba gutakaza amazi byihuse, bizatera gukomera kutaringaniye, kumeneka no kugabanya imbaraga. HPMC irashobora gukora firime nziza ya hydrata muri plaster, igabanya umuvuduko wamazi wamazi, kugirango plaster ibashe gukomeza amazi ahagije mugihe cyumye, ikemeza ko ikomera, bityo ikirinda kubyara.
Kunoza gufatira hamwe: HPMC irashobora gukora firime yoroheje hejuru ya plaster, ishobora kongera imbaraga mugihe ihuye nubuso bwa substrate, kugirango ifatizo rya plaster kurukuta ryiyongere. Cyane cyane kubutaka bworoshye kandi bwumye, ingaruka zo gufata amazi ya HPMC zirashobora kandi kubuza insimburangingo gufata amazi vuba, bityo bikagira ingaruka nziza.
Kongera imbaraga zo guhangana: Gypsumu ireba plaster irashobora kugabanuka kugabanuka kubera ihinduka ryubushyuhe nubushuhe.HPMC bidindiza igipimo cyo kugabanuka kwumye muguhindura igipimo cyamazi cyamazi, bityo bikagabanya neza ibyago byo guturika mumashanyarazi. Muri icyo gihe, firime ya colloid yakozwe na HPMC irashobora kandi gutanga uburinzi bumwe na bumwe bwo kwirinda kumena plaster.
Kunoza imikorere: HPMC irashobora kongera ubwiza bwa plastike na plastike, bikoroha gukora mugihe cyoza no kuringaniza. HPMC itezimbere imikorere ya plaster, kandi abubatsi barashobora kugenzura neza ubunini nuburinganire, bifasha kubona ingaruka nziza yo kurangiza.
3. HPMC itezimbere imikorere ya gypsumu ireba plaster
Kwiyongera kwa HPMC bifite byinshi byahinduye kumikorere ya gypsumu ireba plaster, harimo:
Gutezimbere kw'imiterere: HPMC irashobora kongera cyane ubwiza bwa pompe, kugenzura amazi ya plasta, gukumira ibibazo byo kugabanuka, no kunoza imikorere yo koza plaster.
Kongera ubukonje bukabije: firime ya colloid yakozwe na HPMC igira ingaruka zo gukingira plaster ku rugero runaka, ikabuza plaster gukonja no guturika ahantu hafite ubushyuhe buke, no kunoza ubukonje bwibikoresho.
Kunoza kugabanuka kugabanuka:HPMC byongera ubuhehere buri muri pompe, bikagabanya ikibazo cyo kugabanuka guterwa no guhumeka kwamazi, kandi bigatuma igipande cya plasta gihagarara neza kandi ntigikunze gucika.
Kunonosora neza: Imiterere yo guhuza HPMC irashobora kunoza ifatira rya plaster hejuru yubutaka, bigatuma igifuniko kidashobora kugwa.
4. Kwirinda gukoresha HPMC
Nubwo HPMC ifite ibyiza byinshi bya gypsumu ihura na plaster, ingingo zikurikira nazo zigomba kwitonderwa mugukoresha:
Kugenzura umubare winyongera: Kwiyongera cyane kwa HPMC bizatera plaster gukomera, bigatuma bigorana neza, bigira ingaruka kubikorwa byubwubatsi. Muri rusange, umubare wiyongereye wa HPMC ugomba kugenzurwa murwego rwa 0.1% -0.5%, kandi ugahinduka ukurikije ibikenewe.
Ndetse no kuvanga:HPMC bigomba gukangurwa byuzuye mugihe bivanze nibikoresho nka gypsumu kugirango bitandukane kandi bikore neza. HPMC irashobora gushonga mumazi mbere, hanyuma ikongerwamo gypsumu yo kuvanga, cyangwa irashobora kuvangwa neza murwego rwifu yumye.
Guhuza nibindi byongeweho: Muri gypsumu ireba plaster, HPMC ikoreshwa kenshi nibindi byongeweho, nko kugabanya amazi, kubika amazi, nibindi. Mugihe wongeyeho inyongeramusaruro nyinshi, witondere guhuza kwabo kugirango wirinde imikoranire igira ingaruka kumikorere.
5. Akamaro ka HPMC mu nganda
Muri gypsumu ihura na plaster nibindi bikoresho byubaka, HPMC, nkinyongera yingenzi, igira uruhare runini mugutezimbere imikorere yibikorwa bitewe no gufata neza amazi, gufatana, kubyimba no kurwanya. Mu myaka yashize, hamwe n’ibikenerwa n’ibikoresho byubaka icyatsi, ibiranga kurengera ibidukikije bya HPMC nabyo byatumye isoko ryoroha buhoro buhoro. Mu nyubako zigezweho, HPMC ntabwo itezimbere gusa imikoreshereze ya gypsumu ireba plaster, ahubwo inatezimbere ubwubatsi nubwiza, kandi iteza imbere ivugurura ryikoranabuhanga ryubwubatsi.
Gukoresha HPMC muri gypsumu ireba plaster ntabwo byongera gusa gufata amazi, gufatira hamwe no guhangana n’ibikoresho, ahubwo binatezimbere imikorere yubwubatsi, bigatuma iba inyongera yingirakamaro mubwubatsi. Ibiranga HPMC bidasanzwe hamwe no kunoza imikorere yibice byinshi byatumye irushaho kuba ingirakamaro mubikoresho byubwubatsi, itanga ubufasha bukomeye bwa tekiniki kubwinyubako nziza, iramba cyane. Mugihe kizaza, hamwe niterambere rihoraho ryikoranabuhanga ryubwubatsi, ibyifuzo bya HPMC mubikoresho bishingiye kuri gypsumu bizaba binini.
