Kune akati wandei marudzi e cellulose, uye ndeipi misiyano mukushandiswa kwawo?

Cellulose inogoneka uye yakawanda yakasikwa polymer inowanikwa musero madziro ezvirimwa, ichipa tsigiro yechimiro uye kusimba. Inoumbwa nemayuniti eglucose akabatanidzwa pamwechete kuburikidza ne-β-1,4-glycosidic bond. Nepo cellulose pachayo iri homogeneous substance, marongerwo ayo uye magadzirirwo ayo anoguma mumhando dzakasiyana dzine hunhu hwakasiyana uye mashandisirwo.

1.Microcrystalline Cellulose (MCC):

MCCinogadzirwa nekurapa cellulose fiber nemamineral acids, zvichikonzera diki, crystalline particles.
Zvishandiso: Inoshandiswa zvakanyanya seyakakura mumiriri, binder, uye disintegrant mukugadzirwa kwemishonga senge mahwendefa uye capsules. Nekuda kwehunhu hwayo husina kusimba uye nekudzvanya kwakanyanya, MCC inova nechokwadi chekugovera zvinodhaka zvakafanana uye inofambisa kuburitswa kwezvinodhaka.

2.Cellulose Acetate:

Cellulose acetate inowanikwa neacetylating cellulose ine acetic anhydride kana acetic acid.
Zvishandiso: Rudzi urwu rweselulosi runowanzo shandiswa mukugadzirwa kwefiber dzemachira, kusanganisira zvipfeko uye upholstery. Inoshandiswawo mukugadzira mafirita efodya, firimu remifananidzo, uye mhando dzakasiyana dzemembrane nekuda kwechimiro chayo chinogoneka.

3.Ethylcellulose:

Ethylcellulose inotorwa kubva ku cellulose nekuigadzirisa ne ethyl chloride kana ethylene oxide.
Zvishandiso: Yayo yakanaka kwazvo yekugadzira firimu uye kushorwa kune organic solvents inoita ethylcellulose yakakodzera kupfekedza mahwendefa emishonga, ichipa inodzorwa kuburitswa kwezvinodhaka. Pamusoro pezvo, inoshandiswa mukugadzira ingi, zvinonamira, uye machira ehunyanzvi.

4.Hydroxypropyl Methylcellulose (HPMC):

HPMCinogadzirwa nekutsiva hydroxyl mapoka e cellulose ne methyl uye hydroxypropyl mapoka.
Zvishandiso: HPMC inoshanda seyakakora, stabilizer, uye emulsifier mumaindasitiri akasiyana, kusanganisira chikafu, zvizorwa, uye mishonga. Inowanzo kuwanikwa mune zvigadzirwa zvekuchengeta zvemunhu senge lotions, makirimu, uye mafuta ekuzora, uye mune zvekudya zvinoshandiswa senge sosi, madhirezi, uye ice cream.

5.Sodium Carboxymethyl Cellulose (CMC):

CMC inogadzirwa nekurapa cellulose ne chloroacetic acid uye alkali.
Zvishandiso: Nekuda kwekunyungudika kwayo kwemvura uye kukora zvivakwa,CMCinoshandiswa zvakanyanya seyakagadzikana uye viscosity modifier muzvigadzirwa zvekudya, mishonga, uye maindasitiri ekushandisa. Inowanzo kuwanikwa mune zvakabikwa, zvigadzirwa zvemukaka, mazino, uye detergents.

6.Nitrocellulose:

Nitrocellulose inogadzirwa nenitrate cellulose nemusanganiswa wenitric acid uye sulfuric acid.
Zvishandiso: Inonyanya kushandiswa mukugadzira zvinoputika, lacquers, uye celluloid mapurasitiki. Nitrocellulose-based lacquers yakakurumbira muhuni kupedzisa uye machira emotokari nekuda kwekukurumidza kuoma uye yakakwirira gloss zvivakwa.

7.Bacterial cellulose:

Bacterial cellulose inogadzirwa nemamwe marudzi ebhakitiriya kuburikidza nekuvirisa.
Zvishandiso: Hunhu hwayo hwakasiyana, zvinosanganisira kuchena kwepamusoro, kusimba kwesimba, uye biocompatibility, inoita kuti bhakitiriya cellulose ive yakakosha mukushandisa kwebiomedical sekupfeka maronda, masisitimu engineering scaffolds, uye masisitimu ekutumira zvinodhaka.

Mhando dzakasiyana dze cellulose dzinopa huwandu hwakasiyana hwekushandisa mumaindasitiri akasiyana siyana, anosanganisira emishonga, machira, chikafu, zvekuzora, uye kugadzira. Rudzi rwega rwega rune zvimiro zvakasarudzika zvinoita kuti ive yakakodzera kushandiswa kwakasiyana, kubva pakupa rutsigiro rwechimiro mumapiritsi emishonga kusvika pakunatsiridza magadzirirwo ezvigadzirwa zvekudya kana kushanda seimwe nzira inogoneka mubiotechnology. Kunzwisisa misiyano iyi inogonesa kusarudzwa kwakagadzirirwa kwemhando dze cellulose kuti isangane nezvinodiwa zvekuita mumashandisirwo akasiyana.
