Eteri za selulosi zo gukoresha mu kubaka no gusimbuza sima

Gukoresha ether za cellulose mu byuma by'ubwubatsi no gusigwa ni iterambere ry'ingenzi mu ikoranabuhanga rigezweho ry'ibikoresho by'ubwubatsi. Ntabwo bishobora kunoza imikorere y'ubwubatsi no guhuza imikorere ya sima gusa, ahubwo binanoza imikorere yayo yo kubika amazi, gukora neza no kwirinda kugwa, bityo bikanoza cyane imikorere myiza y'ubwubatsi n'ubwiza bw'inyubako.

1. Ibisobanuro n'ubwoko bwa ether za selulose

Etha za selulosi ni ubwoko bw'ibinyabutabire bya polimeri bitari ioni cyangwa ioni bigizwe no guhindura selulosi karemano mu buryo bwa shimi. Bifite ubushobozi bwo gushonga neza mu mazi no gukora filime kandi bikunze gukoreshwa mu bwubatsi, mu buvuzi, mu biribwa, mu binyabutabire bya buri munsi no mu bindi bikorwa. Mu bwubatsi, etha za selulosi zikunze gukoreshwa cyane ni izi:

Hydroxypropyl methylcellulose (HPMC)

Methyl hydroxyethyl cellulose (MHEC)

Hydroxyethyl cellulose (HEC)

HPMC ikoreshwa cyane mu kubaka no gusimbuza ibumba bitewe nuko ifata amazi neza, ihora ihindagurika cyane mu bushyuhe ndetse n'imikorere yayo myiza mu bwubatsi.

2. Uruhare rwa eteri ya selulosi mu ruganda rw'amabuye

Uduce tw’amabuye dukoreshwa mu guhuza ibikoresho by’amabuye nk’amatafari n’amabuye. Bisaba ko utwo duce tuba dufite uburyo bwo gufatana neza no kubika amazi kugira ngo hirindwe ko ubushuhe bushobora kwinjirwa vuba n’amatafari mu gihe cyo kubaka, bityo bigatera ingaruka ku buryo dufatana.

Kunoza uburyo amazi abikwa

Cellulose ether ifite ubushobozi bwo kubika amazi neza kandi ishobora gukora agahu gato muri mortiwo kugira ngo ifunge ubushuhe no gukumira ubushuhe kwinjirwa vuba cyane mu gihe cyo kubaka. Ibi bifasha sima kuzura amazi, bityo bikanongera imbaraga n'ubufatanye bwa mortiwo.

Kunoza imikorere y'ubwubatsi

Nyuma yo kongeramo eteri ya cellulose, sima y'amabuye irushaho gusigwa neza kandi ikoroha, ifite imiterere myiza, kandi ikagabanya ibibazo by'ubwiza nko gupfuka no kwangirika.

Ongera imikorere y'ubufatanye

Kubika neza amazi no kuyagwiza bituma sima yoroshye gufata ku butaka bw'amatafari n'amabuye, ntibikorohe kugwa, kandi bikongera imikorere myiza y'ubukorikori.

3. Uruhare rwa eteri ya selulosi mu gikoresho cya plaster

Sima ikoreshwa cyane cyane mu gupima no gushariza inkuta z'inyubako, kandi ifite ibisabwa byinshi ku mikorere y'inyubako n'ubwiza bw'ubuso.

Genzura igipimo cy'amazi ya sima

Muri plaster mortier, cellulose ether ishobora gutinza amazi no gutuma amazi arushaho kuba meza, bityo ikongera imbaraga no kugabanya imiyoboro yo gucika.

Irinde kugwa no kunoza imikorere y'inyubako zo ku rukuta

Bitewe n'uko eteri ya selulose igira ubunini bwiza, ishobora kubuza ko sima ya plaster igwa iyo yubatswe ku buso buhagaze, bigatuma ikora neza.

Kunoza ubushobozi bwo gukora

Cellulose ether ituma sima yoroshye kuyitunganya no kuyirangiza, ikongera imikorere myiza y'inyubako n'ubwiza bw'ubuso, kandi irushaho koroshya ubuso no koroshya.

Ubudahangarwa bw'imyanya burushaho kwiyongera

Kunoza uburyo amazi abikwamo no koroherwa bifasha kongera ubushobozi bwo kudacika kw'urukuta rwa plaster no kugabanya ibyago byo kwangirika no kugwa.

4. Ibintu bigira ingaruka ku mikorere ya eteri ya selulose

Imikorere ya eteri ya selulosi ifitanye isano rya hafi n'imiterere yayo ya shimi, urugero rwo gusimbuza (DS), ubunini bw'uturemangingo, ingano y'uduce n'ibindi bintu. By'umwihariko:

Ingano yo gusimbuza:bigira ingaruka ku gushonga kw'amazi no ku gipimo cyo gushonga. Muri rusange, urugero rwo gusimbuza hagati ya 1.4 na 1.9 ni rwo rukwiriye cyane mu bwubatsi.

Ubucucike:Igena ingaruka zayo zo gukomera muri morti, kandi ingano ya viscosity ikoreshwa cyane ni 400 ~ 100.000 mPa·s.

Ingano y'uduce:bigira ingaruka ku buryo ikwirakwira no gushonga kwayo. Uko ingano y'uduce duto, niko ishonga vuba.

5. Igipimo n'uburyo bwo kwirinda

Mu byuma by'amabuye n'ibisimwa, ingano y'inyongera ya eteri ya selulosi muri rusange igenzurwa kuri 0.1% ~ 0.4% (hashingiwe ku bunini bwa sima cyangwa ibikoresho bikoreshwa muri sima). Mu gihe ukoresha, ugomba kwitondera:

Vanga neza neza kugira ngo wirinde kwivangavanga;

Witondere ubushyuhe bwo gushonga n'igihe cya eteri ya selulose;

Imikorere ya ether za cellulose z’ibicuruzwa bitandukanye n’ingano ya viscosity biratandukanye cyane, kandi igipimo cyiza kigomba kugaragazwa binyuze mu igerageza.

Nk'inyongera ifite imikorere myiza cyane,eteri ya selulosebyazamuye cyane imikorere y’ubwubatsi n’ubwubatsi, bituma ubwubatsi burushaho kuba bwiza kandi bufite ireme. Hamwe n’iterambere ry’ibikoresho by’ubwubatsi by’icyatsi kibisi, icyifuzo cya ether za cellulose zitangiza ibidukikije kandi zifite imikorere myiza kizakomeza kwiyongera. Mu bikorwa bifatika, guhitamo ubwoko n’icyitegererezo gikwiye cya ether ya cellulose no kugenzura ingano yayo mu buryo bwa siyansi ni ingenzi mu kwemeza ko imikorere y’imashini y’ubwubatsi yujuje ibisabwa.
