Selilulose Acetate Butyrate, mu magambo ahinnye nka CAB, ifite formula ya chimique (C6H10O5) n n n n n'uburemere bwa molekile bugera kuri miliyoni. Ni ikintu kimeze nk'ifu ikomeye ishongeshwa mu bintu bimwe na bimwe by'umwimerere, nka aside asetiki na aside asetiki. Gushonga kwayo kuriyongera uko ubushyuhe bwiyongera. Selilulose acetate butyrate ifite ubushyuhe buhamye kandi ntiyoroshye kubora mu bushyuhe bw'icyumba.

Selilulose Acetate Butyrate ifite imiterere myiza nko kurwanya ubushuhe, kurwanya UV, kurwanya ubukonje, koroherana, ubwisanzure, no gukingira amashanyarazi, kandi ihura neza na resins na plasticizers zifite aho zibira cyane. Plastike, substrates, filime, n'amabara atandukanye bishobora gukorwa hakurikijwe ingano zitandukanye za butyryl. Ishobora gukorwa hakoreshejwe extrusion, injection molding, rotary molding, blow molding, nibindi, cyangwa hakoreshejwe guteka. Uretse hydroxyl na acetyl, cellulose acetate butyrate inafite ingano za butyryl, kandi imiterere yayo ifitanye isano n'ingano y'amatsinda atatu akora. Aho ishongera n'imbaraga zayo zo gukurura byiyongera uko ingano ya acetyl yiyongera, kandi guhuza kwayo na plasticizers no koroherana kwa filime byiyongera mu rugero runaka uko ingano ya acetyl igabanuka. Ubwiyongere bw'ingano ya hydroxyl bushobora gutuma ishonga mu byuma bishonga. Ubwiyongere bw'ingano ya butyryl butuma ubucucike bugabanuka kandi ingano yo gushonga ikongera kwiyongera.

Gukoresha Cellulose Acetate Butyrate

Selulosi Acetate Butyrate ikoreshwa nk'ikintu cyo kunganya no gukora filime mu gukora ibintu bibonerana cyane kandi birwanya ikirere, filime, n'ibindi bitwikirizo bitandukanye. Ubwiyongere bw'ibikubiye mu matsinda ya butyryl butuma ubucucike bugabanuka kandi ubwiyongere bw'ibitwikirizo bugakomeza kwiyongera. Irimo 12% kugeza 15% by'amatsinda ya acetyl na 26% kugeza 29% by'amatsinda ya butyryl. Ibikoresho bibonerana cyangwa bitagaragara neza, bifite imiterere ikomeye kandi birwanya ubukonje. CAB ishobora gukoreshwa nk'ibikoresho fatizo byo gutegura ibintu bitwikirizo, ibintu bitwikirizo byo mu kirere, filime nto, nibindi. Ishobora kandi gukoreshwa nk'ibikoresho fatizo byo gutwara imiyoboro, ibikoresho byo gufata, insinga, ibimenyetso byo hanze, udusanduku tw'ibikoresho, nibindi. Byongeye kandi, ishobora kandi gukoreshwa nk'ibikoresho fatizo byo gukora ibintu bitwikirizo bishobora gukurwaho, ibintu bitwikirizo, ibintu bitwikirizo biremereye birwanya ikirere, n'imigozi y'ubukorano.

Ibiranga cellulose acetate butyrate

Selulosi ya acetate butyrate ifite imiterere yihariye ituma imenyekana cyane mu bikorwa byayo. Ubwa mbere, ifite ubushobozi bwo gushonga no guhumeka neza, kandi ishobora kuvangwa neza n'ibindi bikoresho kugira ngo igere ku musaruro mwiza wo gutunganya. Icya kabiri, selulosi ya acetate butyrate ifite ubushobozi bwo gufata amazi no guhumeka neza, bigatuma amazi agumana ubushuhe n'ubudahangarwa bw'ibikoresho. Byongeye kandi, ifite ubushobozi bwo guhuza ibintu neza kandi ntizagira ingaruka mbi ku mubiri w'umuntu cyangwa ibidukikije.

Inama ku ikoreshwa rya cellulose acetate butyrate

Mu gihe ukoresha cellulose acetate butyrate, hari inama n'ingamba zimwe na zimwe zishobora gufasha mu gukoresha neza imikorere yayo. Ubwa mbere, cellulose acetate butyrate igomba kumywa mbere yo kuyikoresha kugira ngo yongere ubushobozi bwo gushonga no kugumana ubusugire. Icya kabiri, mu gihe cyo kuyitunganya, hagomba kwirindwa ubushyuhe bwinshi n'imiterere y'aside kugira ngo hirindwe ko cellulose yangirika cyangwa ikangirika. Byongeye kandi, amabwiriza n'amategeko ajyanye nayo agomba gukurikizwa mu gihe cyo kuyikoresha kugira ngo ibikoresho bihuzwe kandi bigerweho neza.

Uburyo bwo gusuzuma ubwiza bwa cellulose acetate butyrate

Ubwiza bwa cellulose acetate butyrate bushobora gupimwa uhereye kuri ibi bikurikira. Ubwa mbere, bushobora kugaragazwa hagenzurwa niba igaragara neza kandi nta mwanda ugaragara irimo. Ubwa kabiri, ubushobozi bwayo bwo gushonga no kuguma neza bushobora gupimwa, kandi cellulose acetate butyrate nziza igomba gushonga neza no kuguma neza mu bushyuhe. Byongeye kandi, birashoboka kandi kureba izina n'icyitegererezo cy'abatanga ibicuruzwa no guhitamo ababitanga bafite icyubahiro kandi babishoboye kugira ngo harebwe ko ibicuruzwa bifite ubuziranenge kandi byizerwa.

Unilong Industry yiyemeje gukora ubushakashatsi kuri esters za cellulose kandi ni ikigo mpuzamahanga gitanga ibicuruzwa bya CAB na CAP. Ishobora gukora toni 4000 za cellulose acetate propionate (CAP) na cellulose acetate butyrate (CAB) buri mwaka, kandi ikoreshwa cyane mu gutunganya ibicuruzwa byoherezwa mu mahanga nko gupfuka, gupakira ibiribwa, ibikinisho by'abana, ibikoresho by'ubuvuzi, nibindi.
