Gusobanukirwa imiterere y'ibinyabutabire bya ethyl cellulose

Selulose ya ethyl ni polymeri ikoreshwa mu buryo butandukanye mu nganda nka farumasi, ibiribwa, irangi, no kwita ku buzima bw'umuntu ku giti cye. Gusobanukirwa imiterere yayo ya shimi ni ingenzi kugira ngo ikoreshe ubushobozi bwayo mu buryo butandukanye n'imikorere itandukanye.

Imiterere y'ibinyabutabire:

Selulosi ya ethyl ikomoka kuri selulosi, polymer karemano iboneka mu bimera. Binyuze mu guhindura imiti, amatsinda ya ethyl yinjizwa ku mugongo wa selulosi, bigatuma habaho selulosi ya ethyl. Imiterere ya ethyl cellulose ishobora kugaragazwa ku buryo bukurikira:

Amatsinda ya Selulosi + Ethyl → Selulosi ya Ethyl Amatsinda ya Selulosi + Ethyl → Selulosi ya Ethyl

Ubwoba bwo mu mazi:

Imwe mu miterere y'ingenzi ya ethyl cellulose ni imiterere yayo yo kudakoresha amazi. Kwinjizwa kw'amatsinda ya ethyl ku mugongo wa cellulose bigabanya polarity ya polymer, bigatuma amazi agabanuka. Uku kudakoresha amazi bituma ethyl cellulose idashonga mu mazi ariko igashonga mu bintu bishongesha nk'amavuta, toluene, na chloroform.

Ubushyuhe bwa thermoplasticity:

Selulosi ya ethyl igaragaza imiterere ya thermoplastic, bivuze ko yoroha iyo ishyushye kandi igakomera iyo ikonje idakoreshejwe imiti ya shimi. Iyi miterere ituma selulosi ya ethyl iba nziza mu buryo butandukanye bwo gutunganya nko gusohora, gushushanya, no gushushanya. Imiterere ya selulosi ya ethyl thermoplastic ituma habaho firime, irangi, n'ibintu byabumbwe bifite imiterere ikenewe ya mekanike.

Imiterere yo Gutunganya Filimi:

Iyo ishongeshejwe mu bintu by’umwimerere bikwiye, ethyl cellulose ishobora gukora uduce dusobanutse, tworoshye kandi tubonerana iyo umuti uvuye mu kirere. Utu duce dufite ubushobozi bwiza bwo kwirinda ubushuhe, imyuka n’amavuta, bigatuma tuba dukwiye gukoreshwa mu gupfuka, gufunga no gupakira.

Guhuza:

Selulose ya ethyl ijyanye n'izindi polymer nyinshi, plasticizers, n'inyongera, bituma habaho imvange zikozwe mu buryo bwihariye zifite imiterere yihariye. Ishobora guhuzwa n'izindi polymer nka polyvinyl acetate (PVA), resins za acrylic, cyangwa se derivatives za cellulose kugira ngo igere ku mikorere myiza mu gusiga, kole, na matrices kugira ngo imiti itange igenzurwe.

Ubudahangarwa bw'ibinyabutabire:

Selulosi ya ethyl igaragaza ubushobozi bwo kudahinduka mu binyabutabire, ikarinda kwangirika bitewe n'urumuri, ubushyuhe na ogisijeni. Ubu buryo bwo kudahinduka butuma ibicuruzwa birimo selulosi ya ethyl bikomeza gukora neza igihe kirekire, cyane cyane mu gihe biramba kandi bikamara igihe kirekire, nk'ibinini n'amatafari yo mu miti.

Umwanzuro:

Mu gusoza, ethyl cellulose ifite imiterere myinshi y'ingenzi ya shimi ituma iba polymer y'agaciro mu nganda zitandukanye. Kuba ifite ubushobozi bwo kudakoresha amazi, ubushyuhe, ubushobozi bwo gukora filime, ubushobozi bwo guhuza, no kudahindagurika kwa shimi bituma ikoreshwa mu bintu bitandukanye, harimo imiti, ibiryo, irangi, no kwita ku buzima bw'umuntu ku giti cye. Gusobanukirwa iyi miterere y'imiti ni ingenzi mu kunoza imikorere n'ubushobozi bw'imiti irimo ethyl cellulose, biganisha ku iterambere ry'ibicuruzwa bishya bifite imiterere n'imikorere byifuzwa.
