Ni ibihe bintu bigira ingaruka ku bucucike bwa hydroxypropyl methylcellulose?

Ku bijyanye no gukoresha sima itose,hydroxypropyl methylcelluloseifite ubushobozi bwiza bwo gukuba, ishobora kongera cyane ubushobozi bwo gufatanya hagati y’urukuta rutose n’urwego rw’ibanze, kandi ishobora no kunoza imikorere ya rukuta idacika, bityo ikoreshwa cyane mu gusiga ibumba, uburyo bwo gukingira inkuta zo hanze n’urukuta rwo gufatanya amatafari.

Kugira ngo irusheho gukomera kwa eteri ya selulosi, ishobora kandi kongera ubushobozi bwo kurwanya gukwirakwira kw'ibikoresho bishya bivanzwe na sima, ndetse ikarinda ibibazo byo gutandukanya, gutandukanya no kuva amaraso muri sima na sima. Ishobora gukoreshwa kuri sima ishyigikiwe na Fibre, sima yo munsi y'amazi na sima yishyira hamwe.

Hydroxypropyl methylcellulose ishobora kongera imikorere y’ibikoresho bishingiye kuri sima. Iyi mikorere ikomoka ahanini ku buryo bungana bwa eteri ya selulose. Muri rusange, igipimo cy’imibare cya viscosity gikoreshwa mu gupima ubukana bwa eteri ya selulose, mu gihe selulose. Ubusanzwe viscosity ya eteri yerekeza ahanini ku gipimo runaka cya eteri ya selulose, ubusanzwe 2%, ku bushyuhe runaka, nka dogere 20 n’igipimo cyo kuzunguruka, hakoreshejwe igikoresho gipimisha cyagenwe, nka viscometer izunguruka. Agaciro k’ubukana.

Ubushyuhe ni kimwe mu bipimo by'ingenzi mu gusuzuma imikorere ya eteri ya selulosi. Uko ubushyuhe bw'umuti wa hydroxypropyl methylcellulose burushaho kwiyongera, ni ko ubushyuhe bw'ibikoresho bishingiye kuri sima burushaho kuba bwiza, kandi ni ko ubushobozi bwo gufatana n'ubutaka burushaho kuba bwiza. Muri icyo gihe, ifite ubushobozi bwo kurwanya kugwa no kurwanya gukwirakwira birakomera, ariko niba ubushyuhe bwayo buri hejuru cyane, bizagira ingaruka ku mikorere y'amazi n'imikorere y'ibikoresho bishingiye kuri sima.

Ni ibihe bintu bigira ingaruka ku bucucike bwa hydroxypropyl methylcellulose? Biterwa ahanini n'impamvu zikurikira.

1. Uko urwego rwo hejuru rwa polymerization ya eteri ya selulosi ya hydroxypropyl methylcellulose, niko uburemere bwayo bwa molekile bwiyongera, bigatuma amazi yayo arushaho kuba menshi.

2. Niba ingano cyangwa ingano ya eteri ya selulosi iri hejuru, ubukana bw'amazi yayo buzaba bwinshi. Ariko, hakwiye kwitonderwa guhitamo ingano ikwiye ya eteri ya selulosi mu gihe uyikoresha, cyane cyane kugira ngo wirinde eteri ya selulosi nyinshi cyane. Bizagira ingaruka ku mikorere ya sima na beto.

3. Kimwe n'ibindi bintu byinshi biva mu mazi, ubushyuhe bwa eteri ya selulose buzagabanuka uko ubushyuhe bwiyongera, kandi uko eteri ya selulose ubwinshi bugenda bwiyongera, niko ubushyuhe bugenda bugabanuka. Uko ingaruka ziba nyinshi.

4. Umuti wa eteri ya selulosi ubusanzwe ni pseudoplastic, ufite imiterere yo gukata shear. Uko umuvuduko wo gukata shear uba munini mu gihe cyo kugerageza, niko viscosity iba nto.

Guhuza kwa mortiweri bizagabanuka bitewe n'imbaraga zo hanze, ibyo bikaba ingirakamaro mu kubaka mortiweri mu buryo bwo gukurura, bigatuma mortiweri ihura neza kandi igakora neza icyarimwe. Ariko, nibaeteri ya seluloseUmuti ugira ingano nyinshi Iyo ubushyuhe buri hasi kandi ubushyuhe bukaba buto, uzerekana imiterere y'amazi ya Newtonian. Iyo ubushyuhe bwiyongere, umuti uzerekana buhoro buhoro imiterere y'amazi ya pseudoplastic, kandi niba ubushyuhe buri hejuru, ubushyuhe bwa pseudoplastic buzarushaho kugaragara.
