Aia kekahi mau ʻano cellulose, a he aha nā ʻokoʻa o kā lākou hoʻohana ʻana?

He polymer kūlohelohe maʻalahi a nui ka Cellulose i loaʻa i loko o nā paia cell o nā mea kanu, e hāʻawi ana i ke kākoʻo kūkulu a me ka paʻa. Hana ʻia ia me nā ʻāpana glucose i hoʻopili ʻia ma o nā pilina β-1,4-glycosidic. ʻOiai he mea like ka cellulose ponoʻī, ʻo ke ʻano o ka hoʻonohonoho ʻana a me ka hana ʻana i nā hopena i nā ʻano like ʻole me nā waiwai a me nā noi like ʻole.

1.Kelulose Microcrystalline (MCC):

MCCHana ʻia ma ka mālama ʻana i nā olonā cellulose me nā waikawa mineral, e hopena ana i nā ʻāpana liʻiliʻi crystalline.
Nā Hoʻohana: Hoʻohana nui ʻia ia ma ke ʻano he mea hoʻonui, mea hoʻopaʻa, a me ka disintegrant i nā ʻano lāʻau lapaʻau e like me nā papa a me nā capsules. Ma muli o kona ʻano inert a me ka compressibility maikaʻi loa, hōʻoia ka MCC i ka hoʻolaha like ʻana o ka lāʻau a hoʻomaʻalahi i ka hoʻokuʻu ʻana i ka lāʻau.

2.Cellulose Acetate:

Loaʻa ka cellulose acetate ma ka acetylating cellulose me ka acetic anhydride a i ʻole ka acetic acid.
Nā Hoʻohana: Hoʻohana pinepine ʻia kēia ʻano cellulose i ka hana ʻana i nā olonā no nā lole, me nā lole a me nā upholstery. Hoʻohana ʻia nō hoʻi ia i ka hana ʻana i nā kānana cigarette, nā kiʻiʻoniʻoni kiʻi, a me nā ʻano membrane like ʻole ma muli o kona ʻano semi-permeable.

3.Ethylcellulose:

Loaʻa ka Ethylcellulose mai ka cellulose ma ka hoʻopili ʻana me ka ethyl chloride a i ʻole ethylene oxide.
Nā Hoʻohana: ʻO kona mau waiwai hana kiʻiʻoniʻoni maikaʻi loa a me ke kūʻē ʻana i nā mea hoʻoheheʻe organik e kūpono ai ka ethylcellulose no ka uhi ʻana i nā papa lāʻau lapaʻau, e hāʻawi ana i ka hoʻokuʻu ʻana i nā lāʻau lapaʻau. Eia kekahi, hoʻohana ʻia ia i ka hana ʻana i nā ʻīnika, nā mea hoʻopili, a me nā uhi kūikawā.

4.Hydroxypropyl Methylcellulose (HPMC):

HPMCUa synthesized ʻia ma ke pani ʻana i nā hui hydroxyl o ka cellulose me nā hui methyl a me hydroxypropyl.
Nā Hoʻohana: Hana ʻo HPMC ma ke ʻano he mea hoʻomānoanoa, mea hoʻopaʻa, a me ka emulsifier ma nā ʻoihana like ʻole, me ka meaʻai, nā mea hoʻonani, a me nā lāʻau lapaʻau. Loaʻa pinepine ia i nā huahana mālama pilikino e like me nā lotions, creams, a me nā poni, a me nā noi meaʻai e like me nā sauces, dressings, a me ka ice cream.

5.Sodium Carboxymethyl Cellulose (CMC):

Hoʻokumu ʻia ʻo CMC ma ka mālama ʻana i ka cellulose me ka waikawa chloroacetic a me ka alkali.
Nā Hoʻohana: Ma muli o kona hiki ke hoʻoheheʻe ʻia i ka wai a me nā waiwai mānoanoa,CMChoʻohana nui ʻia ma ke ʻano he mea hoʻopaʻa a me ka mea hoʻololi viscosity i nā huahana meaʻai, nā lāʻau lapaʻau, a me nā noi ʻoihana. Loaʻa pinepine ia i nā mea i hoʻomoʻa ʻia, nā huahana waiū, ka toothpaste, a me nā detergents.

6. Nitrocellulose:

Hoʻokumu ʻia ka Nitrocellulose ma ka nitrating cellulose me ka hui ʻana o ka waikawa nitric a me ka waikawa sulfuric.
Nā Hoʻohana: Hoʻohana nui ʻia ia i ka hana ʻana i nā mea pahū, nā lacquers, a me nā plastics celluloid. He mea kaulana nā lacquers Nitrocellulose i ka hoʻopau ʻana i ka lāʻau a me nā uhi kaʻa ma muli o ko lākou maloʻo wikiwiki a me nā waiwai ʻālohilohi kiʻekiʻe.

7. Cellulose Bacterial:

Hoʻopili ʻia ka cellulose bacteria e kekahi mau ʻano bacteria ma o ka fermentation.
Nā Hoʻohana: ʻO kona mau waiwai kūikawā, me ka maʻemaʻe kiʻekiʻe, ka ikaika tensile, a me ka biocompatibility, e hoʻolilo i ka cellulose bacteria i mea waiwai nui i nā noi biomedical e like me nā ʻaʻahu ʻeha, nā scaffolds ʻenekinia kiko, a me nā ʻōnaehana lawe lāʻau.

Hāʻawi nā ʻano cellulose like ʻole i nā noi like ʻole ma nā ʻoihana like ʻole, me nā lāʻau lapaʻau, nā lole, ka meaʻai, nā mea hoʻonani, a me ka hana ʻana. Loaʻa i kēlā me kēia ʻano nā waiwai kū hoʻokahi e kūpono ai no nā hoʻohana kikoʻī, mai ka hāʻawi ʻana i ke kākoʻo kūkulu i nā papa lāʻau lapaʻau a hiki i ka hoʻomaikaʻi ʻana i ke ʻano o nā huahana meaʻai a i ʻole ke lawelawe ʻana ma ke ʻano he koho hoʻomau i ka biotechnology. ʻO ka hoʻomaopopo ʻana i kēia mau ʻokoʻa e hiki ai ke koho pono ʻia o nā ʻano cellulose e hoʻokō i nā koi hana kikoʻī i nā noi like ʻole.
