ʻO ka Cellulose, ka mea hoʻohuihui mea ola nui loa ma ka Honua, e hōʻike ana i nā waiwai kupaianaha, ʻo ia ka hiki ke komo i ka wai. Loaʻa kēia ʻano hygroscopic o cellulose i nā noi ākea i nā ʻoihana like ʻole, mai ka textiles a hiki i nā lāʻau lapaʻau. He mea koʻikoʻi ka hoʻomaopopo ʻana i nā hana ma hope o ka hoʻoheheʻe ʻana o ka wai o cellulose no ka hoʻohana ʻana i nā noi like ʻole.
Hoʻolauna:
ʻO Cellulose, he polysaccharide i haku ʻia me nā ʻāpana glucose i hoʻopili ʻia e nā paʻa β(1→4) glycosidic, ʻo ia ka mea hana mua o nā paia o nā mea kanu. ʻO kona nui i ke ʻano, ka hoʻohou, a me ka biodegradability e lilo ia i mea makemake nui no nā noi ʻoihana he nui. ʻO kekahi o nā mea hoihoi o ka cellulose ʻo ia ka hiki ke hoʻopaʻa pono i ka wai. He hopena koʻikoʻi kēia ʻano ma nā ʻano like ʻole e like me ka textiles, ka hana pepa, ka meaʻai, ka lāʻau lapaʻau, a me nā biomaterials. He mea nui ka hoʻomaopopo ʻana i nā ʻano hana e pili ana i ke ʻano hoʻoheheʻe wai o cellulose no ka hoʻohana ʻana i kona hiki piha i kēia mau noi.
Nā mea e hoʻopiʻi ai i ka lawe ʻana i ka wai e ka cellulose:
ʻO kekahi mau mea e hoʻopili i ka hiki ke komo wai o cellulose:
Crystallinity: ʻO ke ʻano crystalline o cellulose e hoʻopilikia nui i kāna mau waiwai hoʻoheheʻe wai. Hōʻike nā ʻāina Crystalline i ka haʻahaʻa haʻahaʻa o ka wai i hoʻohālikelike ʻia me nā ʻāina amorphous ma muli o ke kaohi ʻana i nā molekole wai.
ʻĀpana ʻili: He kuleana koʻikoʻi ka ʻili o nā fiber cellulose i ka lawe ʻana i ka wai. ʻO ka cellulose i hoʻokaʻawale maikaʻi ʻia me kahi ʻāpana ʻoi aku ka nui o ka wai e hoʻohālikelike i nā hale cellulose bulkier.
Hydrophilicity: ʻO nā pūʻulu Hydroxyl (-OH) i loko o nā molekole cellulose e hoʻolilo iā lākou i hydrophilic, e hoʻomaʻamaʻa i ka lawe ʻana i ka wai ma o ka hoʻopili hydrogen.
Degere o ka Polymerization: ʻO ka Cellulose me kahi kiʻekiʻe kiʻekiʻe o ka polymerization e ʻoi aku ka kiʻekiʻe o ka hiki ke komo i ka wai ma muli o ka nui o nā pūʻulu hydroxyl i kēlā me kēia ʻāpana.
Ka Mahana a me ka Haʻahaʻa Pili: ʻO nā kūlana kaiapuni e like me ka mahana a me ka haʻahaʻa pili e hoʻoikaika nui i ke ʻano o ka lawe ʻana i ka wai o cellulose. ʻO nā kiʻekiʻe kiʻekiʻe a me nā pae haʻahaʻa e hoʻonui i ka lawe ʻana i ka wai ma muli o ka piʻi ʻana o ka neʻe ʻana o nā molekole wai.
Nā ʻano o ka hōʻike ʻana:
Hoʻohana ʻia nā ʻano hana like ʻole e hōʻike i ka waiwai o ka wai o ka cellulose:
ʻIkepili Gravimetric: ʻO nā ʻano hana Gravimetric e ana i ka loaʻa ʻana o ke kaumaha o nā laʻana cellulose ma ka ʻike ʻana i ka wai i ka manawa. Hāʻawi kēia i ka ʻikepili quantitative e pili ana i nā kinetics absorption wai a me ka maʻamau equilibrium.
ʻO Fourier Transform Infrared Spectroscopy (FTIR): Hoʻohana ʻia ka FTIR spectroscopy no ka nānā ʻana i nā loli i nā pūʻulu hana o cellulose ma ka lawe ʻana i ka wai. ʻO nā hoʻololi i nā kūlana kiʻekiʻe a me ka ikaika e hōʻike i ka pilina ma waena o cellulose a me nā molekole wai.
X-ray Diffraction (XRD): Hoʻohana ʻia ʻo XRD no ka loiloi ʻana i nā loli o ka crystallinity cellulose ma hope o ka lawe ʻana i ka wai. Hōʻike ka emi ʻana o ka helu crystallinity i ka pehu ʻana o nā fiber cellulose ma muli o ka lawe ʻana i ka wai.
ʻO ka Scanning Electron Microscopy (SEM): E ʻae ʻo SEM i ka ʻike ʻana i nā loli morphological i nā fiber cellulose ma mua a ma hope o ka lawe ʻana i ka wai. Hāʻawi ia i nā ʻike e pili ana i ka kūpaʻa a me ka porosity o nā mea cellulose.
Nā noi o Cellulose ma ke ʻano he Hygroscopic Material:
ʻIke ʻia ke ʻano hygroscopic o cellulose i nā noi like ʻole i nā ʻoihana like ʻole:
Textiles: Hoʻohana nui ʻia nā fiber-based cellulose e like me ka pulupulu a me ka rayon i ka hana lole lole ma muli o ko lākou hiki ke komo i ka makū, hāʻawi i ka hōʻoluʻolu a me ka hanu i nā lole.
ʻO ka hana pepa: ʻO nā fiber cellulose ka mea mua i ka hana pepa. Hoʻopili ko lākou waiwai hoʻoheheʻe wai i ka maikaʻi o ka pepa, hiki ke paʻi, a me ka ikaika.
ʻOihana Meaʻai: Hoʻohana ʻia nā derivatives cellulose e like me ka methylcellulose a me ka carboxymethylcellulose ma ke ʻano he mea mānoanoa, stabilizer, a me nā emulsifiers i nā huahana meaʻai. ʻO kā lākou hiki ke hoʻoheheʻe wai e hoʻonui i ke ʻano a me ka paʻa o ke ola.
ʻO nā lāʻau lapaʻau: Hoʻohana maʻamau ʻia nā mea hoʻohui i ka cellulose i loko o nā ʻano lāʻau lapaʻau no ko lākou hiki ke kāohi i ka hoʻokuʻu ʻana i ka lāʻau, hoʻomaikaʻi i ke kūpaʻa, a hoʻonui i ka bioavailability. Kōkua pū lākou i ka wehe ʻana a me ka hoʻopau ʻana o nā papa a me nā capsules.
Biomaterials: Ke puka mai nei nā cellulose hydrogels a me nā kiʻiʻoniʻoni e like me nā biomaterial hoʻohiki no nā noi biomedical like ʻole, me ka lawe ʻana i ka lāʻau lapaʻau, ka ʻenekinia kiko, a me ka ho'ōla ʻana i ka ʻeha. ʻO kā lākou hiki ke hoʻoheheʻe wai kiʻekiʻe e hiki ai i ka hydration kūpono a me ka hoʻonui cell.
ʻO ka mana kupaianaha o Cellulose e hoʻomoʻa i ka wai mai kona ʻano hana kūikawā a me nā mea kemika. ʻO ka hoʻomaopopo ʻana i nā mea e hoʻopiʻi ai i ka lawe ʻana i ka wai, nā ʻano o ke ʻano, a me ka hoʻohana ʻana o cellulose ma ke ʻano he mea hygroscopic he mea nui ia no ka hoʻonui ʻana i kona hoʻohana ʻana i nā ʻoihana like ʻole. ʻO ka hoʻomau ʻia ʻana o ka noiʻi ʻana ma kēia kahua e hoʻonui i ka laulā o nā noi a kōkua i ka hoʻomohala ʻana i nā mea hoʻomau me nā waiwai hana i hoʻonui ʻia.
