Hydroxypropyl methylcellulose (HPMC)he non-ionic, semi-synthetic polymer i hoʻohana nui ʻia i nā mea kūkulu hale, lāʻau lapaʻau, meaʻai, nā mea hoʻonaninani a me nā ʻoihana ʻoihana ʻē aʻe.
1. Ka waiwai kino a me ke kemika
ʻO ka HPMC he polymer i hana ʻia mai ka cellulose mea kanu maoli ma o ka hoʻololi kemika. He pauda keʻokeʻo keʻokeʻo keʻokeʻo maʻamau, ʻono ʻole, ʻala ʻole a ʻona ʻole. Hiki ke hoʻoheheʻe ʻia i loko o ka wai anuanu a i ʻole ka wai wela e hana ai i kahi hopena colloidal ʻālohilohi a liʻiliʻi paha. Hoʻopili ʻia kona ʻano solubility e ke degere o ka hoʻololi ʻana, ke kaumaha molekala a me ka mahana.
2. Mānoanoa
Loaʻa i ka HPMC nā waiwai mānoanoa maikaʻi loa a hiki ke hoʻonui nui i ka viscosity o ka hoʻonā, e hoʻohana ʻia ia ma ke ʻano he mānoanoa i nā ʻoihana e like me nā mea kūkulu hale, nā uhi, a me nā lāʻau lapaʻau. No ka laʻana, i loko o ka momi sima, hiki iā ia ke hoʻonui i kāna hana hana a me ka hana hana.
3. Paʻa wai
Hiki i ka HPMC ke hoʻemi pono i ka hoʻoheheʻe ʻana o ka wai a hoʻomaikaʻi i ka mana paʻa wai o ka mea. He mea koʻikoʻi kēia waiwai i ka ʻoihana kūkulu hale. No ka laʻana, hiki i ka hoʻohui ʻana i ka HPMC i ka pahu sima a me nā mea gypsum-based hiki ke hoʻolōʻihi i ko lākou manawa wehe, hoʻomaikaʻi i ka maikaʻi o ke kūkulu ʻana, a hōʻemi i ka haki ʻana.
4. Hoʻopili
Ma muli o kāna mau waiwai adhesion maikaʻi, hoʻohana nui ʻia ka HPMC i nā tile adhesives, coatings, adhesives a me nā māla ʻē aʻe. I nā tile adhesives, hiki iā ia ke hoʻonui i ka ikaika paʻa a hoʻomaikaʻi i ka maʻalahi o nā hana kūkulu.
5. Lubricity
Hōʻike ka HPMC i ka lubricity maikaʻi i loko o ka wai wai, kahi e lilo ai ia i mea lubricant maikaʻi i ka hana ʻana i ke kūkulu ʻana, nā uhi, nā mea hoʻonaninani a me nā papa lāʻau lapaʻau, hoʻomaikaʻi i ka hana o ka huahana.
6. Hana ʻili
Loaʻa i ka molecular structure o HPMC nā pūʻulu hydrophilic a me ka hydrophobic, kahi e loaʻa ai kahi hana o ka ʻili a hiki ke pāʻani i ke ʻano o ka emulsification, ka hoʻokuʻu ʻana, ka dispersion a pēlā aku. No laila, hoʻohana ʻia ia i nā uhi, emulsion polymerization, detergents a me nā huahana ʻē aʻe.
7. Paʻakai paʻakai a me ka pH paʻa
ʻO ka HPMC kahi mea polymer non-ionic, no laila ua paʻa ia i nā electrolytes a ʻaʻole maʻalahi e hoʻoheheʻe me nā paʻakai inorganic. Eia kekahi, paʻa ka paʻa i ka pae pH o 3 a 11 a kūpono i nā ʻano like ʻole.
8. Waiwai hana kiʻiʻoniʻoni
Hiki i ka HPMC ke hana i nā kiʻi ʻoniʻoni ma luna o ka ʻili o nā mea like ʻole me ka ikaika mechanical a me ka maʻalahi, no laila ua hoʻohana nui ʻia i ka lāʻau lapaʻau (papa papa), meaʻai (kiʻi pale), uhi (kiʻi kiʻi kōkua), etc.
9. Kūleʻa wela
Loaʻa i ka HPMC ke kūpaʻa wela maikaʻi a hiki ke hoʻomau i kekahi kūlana paʻa i nā wela kiʻekiʻe. E loaʻa iā ia ka gelation thermal i loko o ka wai wai ma lalo o ka mana o ka mahana, ʻo ia hoʻi, e hana ia i ka gel i kahi mahana a hoʻoheheʻe hou ʻia ma hope o ka hoʻoilo. Hoʻohana nui ʻia kēia waiwai i ke kūkulu ʻana, nā meaʻai a me nā ʻoihana lāʻau.
10. Biocompatibility a me ka palekana
ʻO ka HPMC he meaʻawaʻawaʻole,ʻaʻohe mea hoʻonāukiuki polymer me ka biocompatibility maikaʻi, no laila ua hoʻohana nuiʻia i ka lāʻau lapaʻau a me nāʻoihana meaʻai. No ka laʻana, hiki ke hoʻohana ʻia i loko o nā ʻōnaehana hoʻokuʻu i ka lāʻau lapaʻau, nā kulu maka mānoanoa, a me nā mea mānoanoa meaʻai a me nā emulsifiers.
Nā kahua noi
Ma muli o kāna mau waiwai kino a me nā kemika maikaʻi loa, hoʻohana nui ʻia ka HPMC i nā kahua aʻe:
ʻOihana hana: hoʻohana ʻia ma ke ʻano he mānoanoa a me ka mea mālama wai no ka mortar sima, tile adhesive, putty pauka, a me nā huahana gypsum e hoʻomaikaʻi i ka hana hana a me ka hoʻopili.
ʻOihana lāʻau lapaʻau: hoʻohana ʻia ma ke ʻano he lāʻau lapaʻau no nā mea hoʻopili papa, nā mea hoʻokuʻu paʻa, emulsifiers a me stabilizers, etc.
ʻOihana meaʻai: hoʻohana ʻia e like me ka meaʻai mānoanoa, emulsifier, a me ka stabilizer no ka ice cream, ka wai, nā ʻuala a me nā huahana ʻē aʻe.
ʻoihana hoʻonaninani: hoʻohana ʻia i nā huahana mālama ʻili, shampoo, toothpaste, etc., e hāʻawi i ka mānoanoa, emulsification a me nā hopena moisturizing.
ʻoihana hoʻopili: hoʻohana ʻia ma ke ʻano he mea mānoanoa a me ke kōkua kiʻiʻoniʻoni no ka uhi ʻana i ka wai e hoʻomaikaʻi ai i ka kūlike a me ke kūpaʻa o ka uhi.
HPMChe mea polymer maikaʻi loa me nā hiʻohiʻona o ka mānoanoa, ka paʻa ʻana o ka wai, ka hoʻokumu ʻana i ke kiʻiʻoniʻoni, ka lubrication, a me ka hoʻopili ʻana, a ʻaʻohe mea ʻawaʻawa a maikaʻi ʻole, kūpono no nā ʻoihana lehulehu. Hoʻohana nui ʻia ia i ke kūkulu ʻana, ka lāʻau lapaʻau, ka meaʻai, nā mea hoʻonaninani, nā uhi a me nā māla ʻē aʻe e hoʻomaikaʻi i ka maikaʻi o ka huahana a me ka hana. I ka wā e hiki mai ana, me ka holomua o ka ʻenehana a me ka ulu ʻana o ka noi mākeke, hiki ke hoʻonui ʻia ka laulā noi o HPMC a pāʻani i kahi hana koʻikoʻi.
