Polyvinylpyrrolidonekapa ʻia ʻo PVP, ʻo ka helu CAS ʻo 9003-39-8. ʻO ka PVP kahi pūhui polymer hiki ke hoʻoheheʻe ʻia i ka wai i polymerized maiN-vinylpyrrolidone (NVP)malalo o kekahi mau kulana. I ka manawa like, PVP he solubility maikaʻi loa, paʻa kemika, hiki ke hana kiʻiʻoniʻoni, haʻahaʻa toxicity, physiological inertness, wai absorption a me moisturizing hiki, hiki ke hoʻopaʻa ʻia, a me ka hopena adhesive pale. Hiki iā ia ke hui pū me nā mea hoʻohuihui anorganic a me nā mea hoʻohui e like me nā mea hoʻohui, nā mea hoʻohui, nā mea kōkua, etc.

Ua hoʻohana maʻamau ka Polyvinylpyrrolidone (PVP) i nā ʻano like ʻole e like me ka lāʻau lapaʻau, nā mea hoʻonaninani, nā meaʻai a me nā mea inu, brewing, textiles, separation membranes, etc. like photo curing resins, Optical fiber, laser discs, kauo hōʻemi mea, etc. PVP me ka likeʻole maʻemaʻe hiki ke maheleia i eha papa: pharmaceutical grade, kela la i keia kemika papa, meaʻai, a me ka hana hana.

ʻO ke kumu nuiPVPhiki ke hoʻohana ʻia e like me ka co precipitant ʻo ia ka hiki i nā ligands i nā molekala PVP ke hui pū me ka hydrogen hana i nā molekole insoluble. Ma kekahi ʻaoʻao, lilo nā molekele liʻiliʻi i amorphous a komo i nā macromolecules PVP. Ma ka ʻaoʻao ʻē aʻe, ʻaʻole hoʻololi ka hoʻopaʻa ʻana o ka hydrogen i ka hoʻoheheʻe wai o PVP, no laila, ʻo ka hopena, ua hoʻopuehu ʻia nā molekole insoluble i loko o nā macromolecules pVp ma o ka hoʻopaʻa ʻana i ka hydrogen, e maʻalahi ai ka hoʻoheheʻe ʻana. Nui nā ʻano PVP, Pehea mākou e koho ai i kēlā ʻano hoʻohālike i ke koho ʻana. Ke like ka nui (ka nui) o PVP, e emi ana ka hoonui o ka solubility ma ke kauoha o PVP K15>PVP K30>PVP K90. ʻO kēia no ka hoʻololi ʻana o ka hopena solubilization o PVP ponoʻī i ke kauoha o PVP K15>PVP K30>PVP K90. ʻO ka maʻamau, hoʻohana maʻamau ka pVp K 15.

E pili ana i ka hanauna o PVP: NVP wale nō, he monomer, komo i ka polymerization, a ʻo kāna huahana ʻo Polyvinylpyrrolidone (PVP). Hoʻokomo ka monomer NVP i ka hoʻopā ʻana iā ia iho a i ʻole ka NVP monomer e hana i ka hopena copolymerization cross-linking me ka mea hana crosslinking (loaʻa nā pūhui hui unsaturated lehulehu), a ʻo kāna huahana ʻo Polyvinylpyrrolidone (PVPP). Hiki ke ʻike ʻia e hiki ke hana ʻia nā huahana polymerization like ʻole ma ka hoʻomalu ʻana i nā kūlana kaʻina hana polymerization.

Hoʻomaopopo mākou i ke kaʻina hana o PVP

Noi o PVP papa hana: PVP-K moʻo hiki ke hoʻohana 'ia ma ke ano he kiʻiʻoniʻoni, mānoanoa, lubricant a me ka adhesive i kela la i keia oihana kemika, a hiki ke hoʻohana 'ia no ka pele, Moss, lauoho fixative gel, lauoho fixative, etc. a me nā mea hoʻololi no ka mālama ʻana i ka ʻili, nā mea hoʻopaʻapaʻa foam no nā shampoos, nā mea hoʻopuehu a me nā mea hoʻohui no nā mea hoʻonaninani nalu, a me ka ʻaila a me ka pale lā hiki ke hoʻonui i ka hopena pulu a lubricating. ʻO ka lua, ʻo ka hoʻohui ʻana i ka PVP i ka detergent he hopena anti kala maikaʻi a hiki ke hoʻonui i ka hiki ke hoʻomaʻemaʻe.

Ka hoʻohana ʻana i ka PVP ma nā ʻoihana ʻenehana a me nā ʻenehana kiʻekiʻe: Hiki ke hoʻohana ʻia ʻo PVP ma ke ʻano he mea uhi uhi, dispersant, thickener, a hoʻopili i nā puaʻa, paʻi ʻīnika, textiles, paʻi a me ke kala, a me nā paipu kiʻi kala. Hiki i ka PVP ke hoʻomaikaʻi i ka hana hoʻopaʻa ʻana o ka mea hoʻopili i ka metala, aniani, plastik a me nā mea ʻē aʻe. Eia kekahi, hoʻohana nui ʻia ka PVP i nā membrane kaʻawale, nā membrane ultrafiltration, microfiltration membranes, nanofiltration membranes, ʻimi ʻaila, kiʻi curing resins, pena a me nā uhi, Optical fiber, laser discs a me nā ʻano ʻenehana kiʻekiʻe e puka mai ana.

Ka hoʻohana ʻana i ka lāʻau lapaʻau PVP: Ma waena o ka PVP-K series, ʻo k30 kekahi o nā mea hoʻohana synthetic i hoʻohana ʻia, ka mea nui no nā mea hana, nā mea hoʻopili no nā granules, nā mea hoʻokuʻu hoʻomau, nā adjuvants a me nā stabilizers no nā injections, nā mea hoʻoheheʻe, nā dispersants no ka hoʻoheheʻe wai. a me nā chromophores, stabilizers no nā enzymes a me nā lāʻau thermosensitive, co precipitants no ka paʻakikī o ka ʻae ʻana i nā lāʻau lapaʻau, nā mea hoʻonui no nā lubricants ophthalmic, a me nā mea hana kiʻiʻoniʻoni.

Hoʻohana nui ʻia ka Polyvinylpyrrolidone a me kāna mau polymers, e like me nā mea kemika maikaʻi hou i ka lāʻau lapaʻau, ka meaʻai, nā kemika o kēlā me kēia lā, ka paʻi ʻana a me ka waihoʻoluʻu, nā uhi puaʻa, nā mea olaola, nā mea mālama wai a me nā māla ʻē aʻe, me nā manaʻo noiʻi mākeke ākea. Ma hope o nā makahiki o ka ʻimi mau ʻana, ua kūkulu mākou i nā huahana aggregation like ʻole, e like me kēia:

I ka pōkole, ʻoi aku ka maikaʻi o ka hana ʻana o nā huahana PVP a hoʻohana nui ʻia e like me ka polymer additives i ka lāʻau lapaʻau, nā uhi, nā puaʻa, resins, fiber inks, adhesives, detergents, textile printing and dyeing. ʻO PVP, ma ke ʻano he polymer surfactant, hiki ke hoʻohana ʻia ma ke ʻano he dispersant, emulsifier, thickener, leveling agent, viscosity regulator, anti reproduction liquid agent, coagulant, cosolvent, a me ka mea holoi i nā ʻōnaehana dispersion like ʻole.
