Chii chinonzi Cellulose Yakagadzirwa?
Cellulose inonzi polysaccharide, zvinoreva kuti icarbohydrates yakaoma inogadzirwa nemaketani marefu emamorekuru eshuga. Kunyanya, cellulose inoumbwa nekudzokorora zvikamu zveglucose mamorekuru akabatanidzwa pamwechete ne β (1 → 4) glycosidic bonds. Iyi gadziriro inopa cellulose hunhu hwayo hwefibrous chimiro.
Cellulose ndiyo inonyanya kuumbwa chikamu chesero madziro muzvirimwa, ichipa kuomarara, simba, uye tsigiro kumaseru ekudyara nematishu. Iyo yakawanda muzvirimwa-based zvinhu zvakaita sehuni, donje, hemp, flax, uye huswa.
Iyo kemikari formula ye cellulose ndeye (C6H10O5) n, apo n inomiririra nhamba yezvikamu zveglucose mucheni yepolymer. Mamiriro chaiwo uye zvimiro zve cellulose zvinogona kusiyana zvichienderana nezvinhu zvakaita sekwakabva cellulose uye dhigirii repolymerization (kureva, nhamba yemayuniti eglucose mucheni yepolymer).
Cellulose haina kunyungudika mumvura uye yakawanda organic solvents, iyo inobatsira kugadzikana kwayo uye kusimba. Nekudaro, inogona kupunzika kuita mamorekuru ayo eglucose kuburikidza ne enzymatic kana kemikari hydrolysis maitiro, ayo anoshandiswa mune akasiyana maindasitiri ekushandisa, sekugadzira mapepa, kugadzira machira, kugadzirwa kwebiofuel, uye kugadzira chikafu.
