He aha ka Polyvinylpyrrolidone (PVP)?

Polyvinylpyrrolidone, i hoʻopōkole ʻia e like me PVP. Hoʻohana ʻia ia ma ke ʻano he adjuvant, additive, a me excipient ma nā ʻano he nui e like me ka lāʻau lapaʻau, ka lole, ka kemika, ka mea inu, a me nā kemika o kēlā me kēia lā. Wahi a nā koi huahana, hiki ke hoʻokaʻawale ʻia ka PVP i ʻehā ʻano: ka papa ʻoihana, ka papa hoʻonaninani, ka papa meaʻai, a me ka papa lāʻau lapaʻau. Ua hoʻohana nui ʻia nā homopolymers, copolymers, a me nā huahana polymer series cross-linked me nā kaumaha molekala pili mai nā tausani a ʻoi aku ma mua o hoʻokahi miliona ma muli o ko lākou mau waiwai maikaʻi loa a kū hoʻokahi.

Ua māhele ʻia ka PVP i ʻehā pae e pili ana i kona kaumaha molekala awelika, a ua hōʻike pinepine ʻia e nā waiwai K. Hōʻike nā waiwai K like ʻole i ka laulā like o ke kaumaha molekala awelika o PVP. ʻO ka waiwai K he waiwai hiʻohiʻona maoli ia e pili ana i ka viscosity pili o ka wai PVP, a ʻo ka viscosity he nui kino e pili ana i ke kaumaha molekala o nā polymers. No laila, hiki ke hoʻohana ʻia ka waiwai K e wehewehe i ke kaumaha molekala awelika o PVP. ʻO ka maʻamau, ʻo ka nui o ka waiwai K, ʻoi aku ka kiʻekiʻe o kona viscosity a me ka ikaika o kona hoʻopili ʻana. Hiki ke hoʻokaʻawale ʻia nā ʻano huahana nui a me nā kikoʻī o PVP i nā pae viscosity o K-15, K17, K25, K-30, K60, a me K-90 e pili ana i ke kaumaha molekala.

Hiki iā UNILONG INDUSTRY ke hāʻawi i kēia mau meaPVP-Knā huahana moʻo:

PVP, ma ke ʻano he hui polymer wai-soluble synthetic, loaʻa iā ia nā waiwai maʻamau o nā hui polymer wai-soluble, me ka pale colloid, ka hana ʻana i ka kiʻiʻoniʻoni, ka hoʻopili ʻana, ka omo ʻana o ka wai, ka solubilization a i ʻole ka coagulation. Eia nō naʻe, ʻo kona hiʻohiʻona ʻokoʻa loa ʻo ia kona solubility maikaʻi loa a me ka hoʻohālikelike physiological, ka mea i huki i ka manaʻo. I loko o nā polymers synthetic, ʻo PVP, ka mea hiki ke hoʻoheheʻe ʻia i ka wai a me ka hapa nui o nā mea hoʻoheheʻe organik, he haʻahaʻa ka ʻawaʻawa, a me ka hoʻohālikelike physiological maikaʻi, ʻaʻole ʻike pinepine ʻia, ʻoi aku hoʻi i nā kahua e pili kokoke ana i ke olakino kanaka e like me ka lāʻau lapaʻau, ka meaʻai, a me nā mea hoʻonani. Eia kahi hoʻolauna kikoʻī i kāna mau wahi noi:

Ma ke kahua o nā mea hoʻonani o kēlā me kēia lā

I nā mea hoʻonani o kēlā me kēia lā, loaʻa i ka PVP a me ka copolymer ka maikaʻi o ka hoʻokahe ʻana a me ka waiwai hana kiʻiʻoniʻoni. Hiki i ka PVP ke pale i ke colloid i loko o ka lotion, a hiki ke hoʻohana ʻia i loko o nā kirīmi momona a me nā momona ʻole, e like me ka wai hoʻonohonoho, ka mea hoʻohuihui lauoho a me ka mea hoʻonohonoho mousse, ka mea hoʻomaʻemaʻe lauoho sunscreen, ka mea hoʻopaʻa shampoo foam, ka mea hoʻonohonoho nalu, a me ka mea hoʻokahe kala lauoho a me ka mea hoʻohuihui. ʻO ka hoʻohui ʻana i ka PVP i ka kirīmi hau, ka sunscreen, a me nā mea wehe lauoho hiki ke hoʻonui i nā hopena pulu a me ka lubrication.

Kahua holoi

Loaʻa i ka PVP nā waiwai anti-fouling a me repreciation a hiki ke hoʻohana ʻia e hoʻomākaukau i nā wai moakaka a i ʻole nā ​​​​​​mea holoi haumia kaumaha. ʻO ka hoʻohui ʻana i ka PVP i nā detergents he hopena anti-discoloration maikaʻi a hiki ke hoʻonui i ka hiki ke hoʻomaʻemaʻe. I ka holoi ʻana i nā lole, hiki iā ia ke pale i nā detergents synthetic mai ka hoʻonāukiuki ʻana i ka ʻili, ʻoiai nā fibers synthetic. ʻOi aku ka maikaʻi o kēia hana ma mua o nā detergents carboxymethyl cellulose (CMC). Hiki ke hoʻohui ʻia ka PVP me ka borax ma ke ʻano he mea hana kūpono i ka hoʻokumu ʻana o nā mea hoʻomaʻemaʻe phenolic disinfectant. ʻO ka detergent i haku ʻia me PVP a me hydrogen peroxide he mau hana o ka hoʻokeʻokeʻo a me ka pepehi ʻana i nā bacteria.

Ka paʻi ʻana a me ka hoʻoluʻu ʻana i ka lole

He pilina maikaʻi ko PVP me nā dyes organik he nui a hiki ke hui pū me nā fibers synthetic hydrophobic e like me ka polyacrylonitrile, esters, nylon, a me nā mea fibrous e hoʻomaikaʻi i ka mana dyeing a me ka hydrophilicity. Ma hope o ka PVP a me ka nylon grafting copolymerization, ua hoʻomaikaʻi ka lole i hana ʻia i kona kūpaʻa i ka makū a me ke kūpaʻa i ka makū.

Nā uhi a me nā pigments

ʻO nā pena a me nā uhi i uhi ʻia me ka PVP he moakaka me ka ʻole o ka hoʻopilikia ʻana i ko lākou kala kūlohelohe, e hoʻomaikaʻi ana i ka ʻōlinolino a me ka hoʻopuehu ʻana o nā uhi a me nā pigments, e hoʻoikaika ana i ke kūpaʻa wela, a me ka hoʻomaikaʻi ʻana i ka hoʻopuehu ʻana o nā ʻīnika a me nā ʻīnika.

Kahua lapaʻau

Loaʻa i ka PVP ka inertness physiological maikaʻi loa, ʻaʻole ia e komo i ka metabolism kanaka, a he biocompatibility maikaʻi loa, ʻaʻole ia e hoʻonāukiuki i ka ʻili, mucosa, maka, a pēlā aku. ʻO ka PVP papa lapaʻau kekahi o nā mea hoʻohui lāʻau lapaʻau nui ʻekolu i kākoʻo ʻia ma ka honua holoʻokoʻa, hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻopaʻa no nā papa a me nā granules, kahi mea hoʻoheheʻe no nā inikini, a me ke kōkua kahe no nā capsules; Nā mea hoʻomaʻemaʻe, nā mea hoʻonui, nā lubricants a me nā mea hana kiʻiʻoniʻoni no nā kulu maka, nā mea hoʻolaha no nā ʻano wai, nā mea hoʻopaʻa no nā enzymes a me nā lāʻau thermosensitive, a hiki ke hoʻohana ʻia ma ke ʻano he mau mea mālama haʻahaʻa haʻahaʻa. Hoʻohana ʻia no nā aniani hoʻopili e hoʻonui i ko lākou hydrophilicity a me ka lubricity. Eia kekahi, hiki ke hoʻohana ʻia ka PVP ma ke ʻano he mea hoʻoluʻu a me ka mea hoʻohālikelike X-ray; Hiki ke hoʻohana ʻia no nā ʻano dosage like ʻole o nā lāʻau lapaʻau e like me nā papa, granules, a me ka wai. Loaʻa iā ia ka detoxification, hemostasis, hoʻonui i ka hoʻohuihui hoʻoheheʻe ʻana, ka pale ʻana i ka peritoneal adhesion, a me ka hoʻolaha ʻana i ka erythrocyte sedimentation rate. Ua hoʻokuʻu kūhelu ʻia ʻo PVP K30 me ka ʻae ʻia o ka ʻoihana hoʻoponopono lāʻau lapaʻau aupuni.

Ka hana ʻana i ka meaʻai

ʻAʻole carcinogenic ka PVP ponoʻī a he palekana maikaʻi kona no ka meaʻai. Hiki iā ia ke hana i nā hui me nā hui polyphenolic kikoʻī (e like me nā tannins) a hoʻohana nui ʻia ma ke ʻano he mea hoʻomālamalama a hoʻopaʻa i ka hana ʻana i ka meaʻai, e like me ka pia, ka wai huaʻai, a me ka waina. Hiki i ka PVP ke hana i nā hui me nā hui polyphenolic kikoʻī (e like me nā tannins), kahi e pāʻani ai i kahi hana hoʻomālamalama a me ka anticoagulant i nā mea inu wai huaʻai. ʻO ka hoʻohana ʻana o ka cross-linked PVP i loko o ka pia a me nā mea inu kī he mea laha loa ia. Hiki i nā mea polyphenolic i loko o ka pia ke hoʻopaʻa me nā protein i loko o ka pia e hana i nā tannin macromolecular complexes, kahi e hoʻopilikia nui ai i ka ʻono o ka pia a hoʻopōkole i kona ola papa. Hiki i ka crosslinked polyvinylpyrrolidone (PVPP) ke chelate me ka tannic acid a me nā anthocyanins i loko o ka pia, no laila e hoʻomālamalama ana i ka pia, e hoʻomaikaʻi ana i kona kūpaʻa mālama, a e hoʻolōʻihi i kona ola papa. I loko o nā mea inu kī, hiki i ka hoʻohana ʻana o PVPP ke hoʻemi pono i ka nui o nā polyphenols kī, a ʻaʻole noho ka PVPP i loko o nā mea inu kī, e hana hou ana a hoʻemi nui i nā kumukūʻai.

ʻO nā wahi noi nui o PVP i kēia manawa ua kau nui ʻia ma nā ʻoihana kemika a me nā lāʻau lapaʻau o kēlā me kēia lā, a ʻo ka ulu ʻana o kēia mau ʻoihana ʻelua e hoʻomau i ka hoʻokele ʻana i ke koi nui no ka hoʻohana ʻana o PVP i ka wā e hiki mai ana. Ma ke kahua e kū mai ana o PVP, ma ka ʻoihana pākahi lithium, hiki ke hoʻohana ʻia ʻo PVP ma ke ʻano he mea hoʻolaha no nā electrodes pākahi lithium a me ke kōkua hana no nā mea conductive; Ma ka ʻoihana photovoltaic, hiki ke hoʻohana ʻia ʻo PVP ma ke ʻano he mea hoʻolaha e hana i ka pauka kālā spherical kiʻekiʻe no ka hoʻopili kālā electrode maikaʻi, ka pauka kālā e like me ka pepa no ka hoʻopili kālā electrode maikaʻi ʻole, a me nā ʻāpana kālā nano. Me ka hoʻomaikaʻi mau ʻana o ka helu komo ʻana o ka pākahi lithium a me ka hoʻonui ʻana o ka hiki ke hoʻokomo ʻia o ka photovoltaic, e hoʻokele nui kēia mau kahua ʻelua e kū mai ana i ke koi no PVP.

He mea hoʻolako ʻoihana ʻo Unilong, a me kaMoʻo PVPua hoʻomohala ʻia a hana ʻia no nā makahiki he ʻumi. Me nā loli i ka mākeke, ua nele ka lako o nā huahana PVP. I kēia manawa, ua hoʻohui mākou i ʻelua mau laina hana hou, me ka lako lawa a me nā kumukūʻai kūpono. E ʻoluʻolu e nīnau.
