Imikoreshereze
Ubufasha mu kuyungurura: Uburyo bwo kurwanya gufunga, ikintu gifunga; Uburyo bwo gukurura ibintu; Uburyo bwo gutandukanya ibintu; Uburyo bwo gukwirakwiza ibintu; Uburyo bwo kunoza imiterere; Uburyo bwo gukurura amazi. Bigenwa na EEC mu gutunganya inzoga. Nk'uko bivugwa muri GB 2760-96, bifatwa nk'uburyo bwo gutunganya. Dukurikije amabwiriza ya EEC-HACSG, ntibigomba gukoreshwa mu biryo by'abana. Nk'uburyo bwo kurwanya gushonga, mu Bushinwa, byemewe gukoreshwa mu buryohe bw'ifu ikoreshwa ntarengwa ya 50g/kg; ishobora no gukoreshwa muri ice cream ikoreshwa ntarengwa ya 40g/kg; ishobora no gukoreshwa mu mavuta yoroheje n'ifu y'ibinure by'imboga ikoreshwa ntarengwa ya 20.0g/kg. Iyo amatsinda ya hydroxyl muri macromolecule ya cellulose anyura mu buryo bwo gupima cyangwa gupima, ibintu byinshi by'ingirakamaro bishobora guturukamo. Esters za cellulose zikoreshwa mu by'ukuri zirimo: nitrati ya cellulose, acetate ya cellulose, acetate ya cellulose butyrate na xanthate ya cellulose. Eteri za selulosi zirimo: selulosi ya methyl, selulosi ya karboksimeti, selulosi ya ethyl, selulosi ya hydroxyethyl, selulosi ya cyanoethyl, selulosi ya hydroxypropyl na selulosi ya hydroxypropyl methyl, nibindi. Byongeye kandi, hari ibikomoka kuri ester-ether bivanze. Selulosi ya microcrystalline ishobora gukoreshwa mu nganda nk'imyenda, imyenda, inzoga, ibiryo, n'impapuro.
Selulosi ya microcrystalline muri rusange ifite ubucucike buke ku bicuruzwa byumye bikonjeshejwe n'ubucucike bwinshi ku bicuruzwa byumye bipfapfaizwa. Ubushuhe bungana na 5%. Selulosi ya microcrystalline irashongeshwa ariko ntishongeshwa mu mazi, ntishongeshwa mu binyabutabire bivanze, mu binyabutabire by’umwimerere n’amavuta, irabyimba kandi igashonga igice mu bisubizo bya alkaline bivanze. Gusuka ifu ya microcrystalline mu mazi bitanga gel cyangwa paste yera ibonerana. Uretse iyo ivanze cyane, igumaho imyaka myinshi.
Gupakira no Kohereza
nk'ibisabwa n'abakiriya.
Ni iy'ibicuruzwa rusange kandi ishobora gutangwa binyuze mu nyanja no mu kirere
Bika kandi ubibike
Igihe cyo kubika: Amezi 24 uhereye igihe byakorewe mu ipaki y’umwimerere idafunguye, bibitswe ahantu hakonje kandi humutse, kure y’izuba ryinshi, amazi.
Ububiko bufite umwuka uhagije, Butuma ibintu bishya bishyuha, butandukanyijwe n'ibikomoka kuri okiside, aside.
