He aha ka Polyvinylpyrrolidone (PVP)?

Polyvinylpyrrolidone, i hōʻoki ʻia ʻo PVP. ʻO ka Polyvinylpyrrolidone (PVP) kahi pūhui polymer non-ionic i hana ʻia e ka polymerization o N-vinylpyrrolidone (NVP) ma lalo o kekahi mau kūlana. Hoʻohana ʻia ia ma ke ʻano he adjuvant, additive, a me ka excipient ma nā ʻano he nui e like me ka lāʻau lapaʻau, textile, kemika, ka mea inu, a me nā lāʻau lāʻau. E like me nā koi huahana, hiki ke hoʻokaʻawale ʻia ka PVP i ʻehā mau ʻano: ʻoihana ʻoihana, ʻoihana hoʻonaninani, papa meaʻai, a me ka papa lāʻau lapaʻau. Homopolymers, copolymers, a me nā huahana polymer series cross-linked me nā kaupaona molekala pili mai nā tausani a ʻoi aku i hoʻokahi miliona ua hoʻohana nui ʻia ma muli o ko lākou mau waiwai maikaʻi a kū hoʻokahi.

Ua māhele ʻia ʻo PVP i ʻehā mau pae e pili ana i kona kaumaha molekala awelika, a ua hōʻike pinepine ʻia e nā koina K. Hōʻike nā helu K ʻokoʻa i ka laulā kūpono o ka awelika molekala kaumaha o PVP. ʻO ka waiwai K he waiwai ponoʻī e pili ana i ka viscosity pili o ka solution aqueous PVP, a ʻo ka viscosity ka nui kino pili i ke kaumaha molekala o nā polymers. No laila, hiki ke ho'ohana 'ia ka waiwai K no ka 'ike 'ana i ka 'awelika molecular kaumaha o PVP. ʻO ka maʻamau, ʻoi aku ka nui o ka waiwai K, ʻoi aku ka kiʻekiʻe o kona viscosity a ʻoi aku ka ikaika o kāna adhesion. 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 i ka UNILONG INDUSTRY ke hāʻawi i kēiaPVP-Khuahana moʻo:

PVP, ma ke ano he synthetic water-soluble polymer compound, loaʻa nā waiwai maʻamau o ka wai-soluble polymer compounds, me ka pale colloid, film-forming, bonding, moisture absorption, solubilization or coagulation. Eia nō naʻe, ʻo kāna hiʻohiʻona ʻokoʻa loa ʻo ia kona solubility maikaʻi loa a me ka hoʻohālikelike ʻana i ka physiological, ka mea i huki i ka nānā. I loko o nā polymers synthetic, ʻaʻole ʻike pinepine ʻia ka PVP, ka mea hiki ke hoʻoheheʻe ʻia i loko o ka wai a me ka hapa nui o nā mea hoʻoheheʻe kūlohelohe, ʻaʻole i ʻike pinepine ʻia, ʻoi aku ka maikaʻi ma nā kula pili i ke olakino kanaka e like me ka lāʻau lapaʻau, ka meaʻai, a me nā mea hoʻonaninani. ʻO kēia ka hoʻolauna kikoʻī i kāna mau wahi noi:

Ma ke kahua o nā mea hoʻonaninani i kēlā me kēia lā

I nā mea hoʻonaninani i kēlā me kēia lā, loaʻa i ka PVP a me ka copolymer ka dispersibility maikaʻi a me ka waiwai hana kiʻiʻoniʻoni. Hiki i ka PVP ke pale aku i ka colloid i loko o ka lotion, a hiki ke hoʻohana ʻia i loko o nā momona momona a momona ʻole, e like me ka hoʻonohonoho ʻana i ka wai, ka lauoho lauoho a me ka mea hoʻonohonoho mousse, ka pale pale lauoho lauoho, ka shampoo foam stabilizer, ka mea hoʻonohonoho nalu, a me ka dispersant lauoho lauoho a me ka mea hoʻohui. ʻO ka hoʻohui ʻana i ka PVP i ka ʻaila hau, ka sunscreen, a me nā mea hoʻoneʻe lauoho hiki ke hoʻonui i ka hopena pulu a me ka lubrication.

Kahua holoi

Loaʻa iā PVP nā waiwai anti fouling a re precipitation a hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā wai aniani a i ʻole nā ​​​​mea holoi hoʻoheheʻe kaumaha. ʻO ka hoʻohui ʻana i ka PVP i nā detergent 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 detergent synthetic mai ka hoʻonāukiuki ʻana i ka ʻili, ʻoi aku ka nui o nā fiber synthetic. ʻOi aku ka maikaʻi o kēia hana ma mua o ka carboxymethyl cellulose (CMC) detergents. Hiki ke hoʻohui ʻia ʻo PVP me ka borax ma ke ʻano he mea hana pono i ka hoʻokumu ʻana i nā mea hoʻomaʻemaʻe disinfectant phenolic. ʻO ka mea hoʻomaʻemaʻe i haku ʻia me ka PVP a me ka hydrogen peroxide nā hana o ka bleaching a me ka pepehi ʻana i ka bacteria.

Ka paʻi lole a me ka waihoʻoluʻu

He pilina maikaʻi ko PVP me nā mea kalaola he nui a hiki ke hui pū me nā fiber synthetic hydrophobic e like me polyacrylonitrile, esters, nylon, a me nā mea fibrous e hoʻomaikaʻi ai i ka mana kala 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 ʻana a me ka pale ʻana i ka wai.

Nā uhi a me nā puaʻa

ʻO nā pena a me nā uhi i uhi ʻia me ka PVP he akaka me ka ʻole o ka hoʻopili ʻana i ko lākou kala maoli, hoʻomaikaʻi i ka ʻōlinolino a me ka hoʻopuehu ʻana o nā uhi a me nā puaʻa, hoʻonui i ka paʻa wela, a hoʻomaikaʻi i ka dispersibility o nā inika a me nā inika.

Kahua lapaʻau

ʻO ka PVP ka maikaʻi physiological inertness, ʻaʻole komo i ka metabolism kanaka, a he biocompatibility maikaʻi loa, ʻaʻole ia e hoʻonāukiuki i ka ʻili, mucosa, maka, a me nā mea ʻē aʻe. hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻopaʻa no nā papa a me nā granules, he co solvent no nā injections, a me kahi kōkua kahe no nā capsules; Detoxifiers, extenders, lubricants a me nā mea hana kiʻiʻoniʻoni no ka hāʻule o ka maka, dispersants no ka hoʻoheheʻe wai, stabilizers no nā enzymes a me nā lāʻau thermosensitive, a hiki ke hoʻohana ʻia e like me nā preservatives haʻahaʻa. Hoʻohana ʻia no nā lens contact e hoʻonui i kā lākou hydrophilicity a me ka lubricity. Eia kekahi, hiki ke hoʻohana ʻia ʻo PVP ma ke ʻano he kala a me ka X-ray contrast agent; Hiki ke hoʻohana ʻia no nā ʻano lāʻau like ʻole e like me nā papa, granules, a me ka wai. Loaʻa iā ia ka detoxification, hemostasis, hoʻonui i ka neʻe ʻana o ka dissolution, pale ʻana i ka pili ʻana o peritoneal, a me ka hoʻonui ʻana i ka helu sedimentation erythrocyte. Ua hoʻolaha ʻia ʻo PVP K30 me ka ʻae ʻia o ka ʻoihana hoʻoponopono lāʻau lapaʻau aupuni.

ʻO ka hana meaʻai

ʻO ka PVP ponoʻī ʻaʻole ia he carcinogenic a he palekana ka meaʻai maikaʻi. Hiki iā ia ke hana i nā paʻakikī me nā pūhui polyphenolic kūikawā (e like me nā tannins) a hoʻohana nui ʻia ma ke ʻano he mea hoʻomaʻamaʻa a hoʻopaʻa i ka hana ʻai, e like me ka pia, ka wai huaʻai, a me ka waina. Hiki i ka PVP ke hana i nā paʻakikī me nā pūhui polyphenolic kikoʻī (e like me nā tannins), e pāʻani ana i kahi hana wehewehe a me ka anticoagulant i nā mea inu wai hua. Hoʻolaha nui ʻia ka hoʻohana ʻana i ka PVP pili i ka pia a me nā mea inu kī. 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. Hiki i ka crosslinked polyvinylpyrrolidone (PVPP) ke chelate me ka waikawa tannic a me nā anthocyanins i loko o ka pia, ma laila e hoʻomaʻamaʻa ai i ka pia, hoʻomaikaʻi i kona kūpaʻa mālama ʻana, a hoʻolōʻihi i kona ola paʻa. Ma nā mea inu kī, hiki i ka hoʻohana ʻana i ka PVPP ke hōʻemi pono i ka ʻike o nā polyphenols kī, a ʻaʻole noho ʻo PVPP i nā mea inu kī, hiki ke hoʻohana hou ʻia a hoʻemi nui i nā kumukūʻai.

ʻO nā wahi noi nui o PVP i kēia manawa i ka ʻoihana kemika a me nā lāʻau lapaʻau i kēlā me kēia lā, a e hoʻomau ka ulu ʻana o kēia mau ʻoihana ʻelua i ka koi nui no ka hoʻohana ʻana i ka PVP i ka wā e hiki mai ana. Ma ke kahua e puka mai ana o PVP, ma ka ʻoihana pākaukau lithium, hiki ke hoʻohana ʻia ka PVP ma ke ʻano he dispersant no nā electrodes pākahi lithium a me kahi kōkua hana no nā mea conductive; I loko o ka ʻoihana photovoltaic, hiki ke hoʻohana ʻia ka PVP ma ke ʻano he dispersant no ka hana ʻana i ka pauka kālā spherical kiʻekiʻe no ka paʻi kālā electrode maikaʻi, ka pauka kālā e like me ka pepa no ka paʻi kālā electrode maikaʻi ʻole, a me nā ʻāpana kālā nano. Me ka hoʻomau mau ʻana o ka nui o ke komo ʻana o ka pā lithium a me ka piʻi ʻana o ka hiki ke hoʻokomo ʻia i ka photovoltaic, ʻo kēia mau māla e puka mai nei e hoʻokau nui i ka noi no PVP.

ʻO Unilong kahi mea hoʻolako ʻoihana, a ʻo kaPVP moʻoua kūkulu ʻia a hana ʻia no ʻumi makahiki. Me nā hoʻololi i ka mākeke, ʻo ka hāʻawi ʻana i nā huahana PVP i ka pōkole. I kēia manawa, ua hoʻohui mākou i ʻelua mau laina hana, me ka lako lako a me nā kumukūʻai maikaʻi. E ʻoluʻolu e nīnau.
