Guhindura ibinyamisogwe
Yitwa kandi inkomoko ya krahisi, ikorwa nu mubiri, mu buryo bwa shimi cyangwa mu buryo bwo kuvura hamwe na krahisi kavukire kugirango ihindure, ishimangire cyangwa yangize imitungo mishya ikoresheje molekile clavage, guhinduranya cyangwa gutangiza amatsinda mashya asimbuye.Hariho uburyo bwinshi bwo guhindura ibinyamisogwe byibiribwa, nko guteka, hydrolysis, okiside, guhumanya, okiside, esterification, etherification, guhuza hamwe nibindi.
Guhindura kumubiri
1. Mbere ya gelatinisation
2. Kuvura imirasire
3. Kuvura ubushyuheGuhindura imiti
1. Esterification: Acetylated krahisi, igereranywa na anhydride ya acetike cyangwa vinyl acetate.
2. Etherification: Hydroxypropyl krahisi, yatewe na okiside ya propylene.
3. Acide ivura ibinyamisogwe, bivurwa na acide organique.
4. Alkaline ivura ibinyamisogwe, bivurwa na alkaline idasanzwe.
5. Amashanyarazi avanze, yakozwe na hydrogen peroxide.
6. Oxidation: Oxidized krahisi, ivurwa na sodium hypochlorite.
7. Emulisifike: sodium ya sodiyumu Octenylsuccine, igereranywa na octenyl succinic anhydride.
