Kune mhando dzakasiyana dze cellulose, uye ndedzipi musiyano uripo pakushandiswa kwadzo?

Cellulose ipolymer yechisikigo inoshanduka-shanduka uye yakawanda inowanikwa mumadziro emasero emiti, ichipa rutsigiro rwechimiro uye kuomarara. Inoumbwa nemayuniti eglucose akabatana kuburikidza nemabhondi eβ-1,4-glycosidic. Kunyange zvazvo cellulose pachayo iri chinhu chakafanana, nzira yainorongwa uye inogadziriswa nayo inoguma nemhando dzakasiyana dzine hunhu hwakasiyana uye mashandisirwo akasiyana.

1. Microcrystalline Cellulose (MCC):

MCCinogadzirwa nekurapa fibers dze cellulose ne mineral acids, zvichikonzera zvidimbu zvidiki, zvakaita se crystalline.
Mashandisirwo: Inoshandiswa zvakanyanya semushonga wekuwedzera, wekubatanidza, uye wekubvisa mishonga mumishonga yakaita semapiritsi nemakapisi. Nekuda kwekusashanda kwayo uye kudzvanywa kwayo kwakanaka, MCC inoita kuti mishonga iparadzirwe zvakaenzana uye inobatsira kuburitswa kwemishonga.

2. Cellulose Acetate:

Cellulose acetate inowanikwa ne acetylating cellulose ne acetic anhydride kana acetic acid.
Mashandisirwo: Rudzi urwu rwe cellulose runonyanya kushandiswa mukugadzira machira, kusanganisira mbatya nemidziyo yemumba. Runoshandiswawo mukugadzira mafirita efodya, firimu remifananidzo, uye mhando dzakasiyana dzema membrane nekuda kwehunhu hwayo hwekunyorova zvishoma.

3.Ethylcellulose:

Ethylcellulose inotorwa kubva ku cellulose kuburikidza nekuisanganisa ne ethyl chloride kana ethylene oxide.
Mashandisirwo: Hunhu hwayo hwakanaka hwekugadzira firimu uye kuramba kwayo zvinonyungudutsa zvinoita kuti ethylcellulose ive yakakodzera kuputira mapiritsi emishonga, zvichiita kuti mishonga ibude zvakanaka. Uyezve, inoshandiswa mukugadzira inki, manamati, uye machira akakosha.

4.Hydroxypropyl Methylcellulose (HPMC):

HPMCinogadzirwa nekutsiva mapoka ehydroxyl ecellulose nemapoka emethyl nehydroxypropyl.
Mashandisirwo: HPMC inoshanda semushonga wekuomesa, kusimbisa, uye emulsifier mumaindasitiri akasiyana-siyana, anosanganisira chikafu, zvizoro, uye mishonga. Inowanikwa zvakanyanya muzvigadzirwa zvekuchengetedza muviri zvakaita semafuta ekuzora, mafuta ekuzora, uye mafuta ekuzora, pamwe chete nemuzvikafu zvakaita semasosi, madhirezi, uye ice cream.

5. Sodium Carboxymethyl Cellulose (CMC):

CMC inogadzirwa nekurapa cellulose ne chloroacetic acid uye alkali.
Mashandisirwo: Nekuda kwekunyungudika kwayo mumvura yakawanda uye kugona kwayo kukora,CMCInoshandiswa zvakanyanya senzira yekugadzirisa kusimba kweganda uye kusimba kweganda muzvigadzirwa zvekudya, mishonga, uye mashandisirwo emaindasitiri. Inowanzo kuwanikwa muzvinhu zvakabikwa, zvigadzirwa zvemukaka, mushonga wemazino, uye sipo.

6.Nitrocellulose:

Nitrocellulose inogadzirwa ne nitrating cellulose nemusanganiswa we nitric acid ne sulfuric acid.
Mashandisirwo: Inonyanya kushandiswa mukugadzira zvinhu zvinoputika, malacquers, uye mapurasitiki e celluloid. Malacquers akagadzirwa ne nitrocellulose anozivikanwa mukugadzira mapuranga uye machira emotokari nekuda kwekuoma kwawo nekukurumidza uye kupenya kwakanyanya.

7. Cellulose yebhakitiriya:

Maseruyuru ebhakitiriya anogadzirwa nemamwe marudzi emabhakitiriya kuburikidza nekuvirisa.
Mashandisirwo: Hunhu hwayo hwakasiyana, kusanganisira kuchena kwakanyanya, simba rekudhonza, uye kubatana kwezvinhu zvipenyu, zvinoita kuti cellulose yemabhakitiriya ive yakakosha mukushandiswa kwemishonga senge maronda, ma tissue engineering scaffolds, uye masisitimu ekutumira mishonga.

Mhando dzakasiyana-siyana dze cellulose dzinopa mashandisirwo akasiyana-siyana mumaindasitiri akasiyana-siyana, anosanganisira mishonga, machira, chikafu, zvizoro, uye kugadzira. Rudzi rumwe nerumwe rune hunhu hwakasiyana hunoita kuti rukodzere kushandiswa kwarwo, kubva pakupa rutsigiro rwechimiro mumapiritsi emishonga kusvika pakuvandudza magadzirirwo ezvigadzirwa zvekudya kana kushanda seimwe nzira inogara kwenguva refu mu biotechnology. Kunzwisisa misiyano iyi kunoita kuti kusarudzwa kwemhando dze cellulose kuenderane nezvinodiwa zvekushanda kwakasiyana-siyana.
