menyekanisha:
Eteri za selulosi zikoreshwa cyane mu nganda z'ubwubatsi bitewe n'ubushobozi bwazo bwiza bwo kubika amazi, kuyakomeza no kuyahuza. Zinoza uburyo ibikoresho bishingiye kuri sima bigenda neza kandi zigatunganywa neza, kandi zikongera imiterere y'ibikoresho bya nyuma. Puti zikunze gukoreshwa mu nganda z'ubwubatsi mu kuzuza imyenge, imyobo n'ibindi bintu bidafite ishingiro ku nkuta no ku gisenge. Gukoresha eteri za selulosi mu ifu ya puti bishobora kunoza ubushobozi bwo gukora, gushyiraho igihe n'ubwiza bw'umusaruro muri rusange. Iyi nkuru izavuga ku ngaruka z'ubushyuhe butandukanye bwa eteri za selulosi ku ifu ya puti.
Ubwoko bwa ether za selulosi:
Hari ubwoko butandukanye bwa ether za selulosi harimo methylcellulose (MC), hydroxypropylmethylcellulose (HPMC), ethylcellulose (EC) na carboxymethylcellulose (CMC). HPMC ni ether ya selulosi ikunzwe cyane mu nganda z'ubwubatsi bitewe n'ubushobozi bwayo bwiza bwo kubika amazi, kuyakomera no kuyafata. HPMC iza mu buryo butandukanye, kuva ku buke kugeza ku burebure.
Ingaruka za eteri ya selulosi ku ifu ya putty:
Ifu ya putty ikoreshwa mu kuzuza imiyoboro, imyobo n'ibindi bintu bidafite ishingiro ku nkuta no ku gisenge. Gukoresha ether za cellulose mu ifu ya putty bishobora kunoza imikorere n'igihe cy'umusaruro. Ether ya cellulose ishobora kandi kunoza imikorere n'uburyo ifu ya putty ifatana. Ibi bikurikira ni ingaruka z'ubushyuhe butandukanye bwa ether za cellulose ku ifu ya putty:
1. Uburemere buke bwa HPMC:
HPMC ifite ubushyuhe buke kandi ikora neza ishobora kongera ubushyuhe n'ubushobozi bwo gukora bw'ifu ya putty. Inanoza igihe cyo gushyiraho ibicuruzwa. HPMC ifite ubushyuhe buke bwo gukaraba, ibi bikaba bishobora kubuza ifu ya putty gukomera vuba cyane. Ishobora kandi kunoza uburyo ifatana n'uburyo ifatana. HPMC ifite ubushyuhe buke kandi ikwiriye ifu ya putty isaba ubushobozi bwo gukora no koroha.
2. Uburemere buri hagati ya HPMC:
HPMC ifite ubukana buringaniye ishobora kongera imiterere ya thixotropic y'ifu ya putty. Ishobora kandi kunoza imikorere y'amazi no gufatanya kw'ibicuruzwa. HPMC ifite ubukana buringaniye ishobora kunoza imiterere y'imikorere y'ibicuruzwa, nko gukomera no kuramba. Ikwiriye ifu ya putty isaba kubika amazi neza no guhuza neza.
3. HPMC ifite ubukana bwinshi:
HPMC ifite ubukana bwinshi ishobora kunoza imikorere y'ifu ya putty mu kubyimba no kurwanya kugwa. Ishobora kandi kunoza imikorere y'amazi no gufatanya kw'ibicuruzwa. HPMC ifite ubukana bwinshi ishobora kunoza imiterere y'imikorere y'ibicuruzwa, nko gukomera no kuramba. Ikwiriye ifu ya putty isaba ubukana bwinshi no kurwanya kugwa.
mu gusoza:
Eteri za selulosi zikoreshwa cyane mu nganda z'ubwubatsi bitewe n'ubushobozi bwazo bwiza bwo kubika amazi, kuyakomeza no kuyahuza. HPMC yabaye eteri ya selulosi ikunzwe cyane mu nganda z'ubwubatsi kubera imiterere yayo myiza. HPMC iza mu buryo butandukanye, kuva ku buke kugeza ku burebure. Gukoresha eteri za selulosi zifite ubukana butandukanye bishobora kunoza imikorere, igihe cyo gushyiraho, imikorere ya thixotropic, kubika amazi, imikorere yo guhuza n'imiterere ya mekanike y'ifu ya putty. Gukoresha eteri za selulosi bishobora kunoza ubwiza n'imikorere y'ifu ya putty, bigatuma ikoreshwa mu buryo butandukanye mu nganda z'ubwubatsi.
