Polyvinylpyrrolidoneua ta'ua foi PVP, numera CAS o le 9003-39-8. O le PVP ose fa'apipi'i fa'apolopolo e mafai ona solu vai e fa'aputuina maiN-vinylpyrrolidone (NVP)i lalo o nisi tulaga. I le taimi lava e tasi, o le PVP e sili ona lelei le solubility, mautu vailaʻau, gaioiga faʻapipiʻi ata, maualalo oona, le faʻaogaina o le tino, faʻaogaina o le vai ma le faʻaleleia o le malosi, mafai faʻapipiʻi, ma le faʻaogaina o le puipuiga. E mafai ona tuʻufaʻatasia ma le tele o mea faʻapipiʻi ma mea faʻapitoa e pei o faʻaopoopoga, faʻaopoopoga, mea faʻapipiʻi, ma isi.

Polyvinylpyrrolidone (PVP) ua masani ona faaaogaina i vaega eseese e pei o vailaau, cosmetics, meaai ma meainu, brewing, textiles, separation membranes, ma isi. Faatasi ai ma le atinae o oloa fou faasaienisi ma faatekinolosi, ua faaaogaina PVP i ia fanua maualuga-tech e pei o resins curing ata, Optical fibre, tisiki leisa, toso faaititia mea e mafai ona vaevaeina PVP, ma isi. vasega, vasega kemikolo i aso uma, vasega mea'ai, ma tulaga tau alamanuia.

O le mafuaaga autuPVPe mafai ona faʻaaogaina e avea o se faʻalavelave faʻatasi o le ligands i molelaʻau PVP e mafai ona tuʻufaʻatasia ma le hydrogen malosi i mole mole e le mafai ona faʻaaogaina. I le tasi itu, o molelaʻau laiti e avea ma amorphous ma ulufale i le PVP macromolecules. I le isi itu, o le faʻapipiʻiina o le hydrogen e le suia ai le solubility o le vai o le PVP, o le mea lea o le iʻuga o molelaʻau e le mafai ona faʻasalalau e faʻasalalau i le pVp macromolecules e ala i le faʻaogaina o le hydrogen, e faigofie ai ona faʻamavae. E tele ituaiga o PVP, E faʻafefea ona tatou filifilia lena faʻataʻitaʻiga pe a filifilia. A tutusa le aofaʻi (mass) o le PVP, o le faʻateleina o le solubility e faʻaitiitia i le faasologa o le PVP K15>PVP K30>PVP K90. E mafua ona o le solubilization aafiaga o le PVP lava ia suia i le faasologa o PVP K15>PVP K30>PVP K90. E masani lava, pVp K 15 e masani ona fa'aaogaina.

E uiga i le gaosiga o le PVP: naʻo le NVP, o se monomer, e auai i le polymerization, ma o lona oloa o le Polyvinylpyrrolidone (PVP). O le NVP monomer e o'o i le fa'afeso'ota'i o le tagata lava ia po'o le NVP monomer o lo'o feagai ma le fa'aogaina o le copolymerization fa'afeso'ota'i fa'atasi ma le so'o fa'afeso'ota'i (o lo'o i ai le tele o fa'alapotopotoga e le'i tumu), ma o lona oloa o le Polyvinylpyrrolidone (PVPP). E mafai ona iloa e mafai ona gaosia oloa polymerization eseese e ala i le pulea o tulaga faiga polymerization eseese.

Matou te malamalama i le faagasologa o le PVP

Fa'aaogāga PVP vasega alamanuia: PVP-K fa'asologa e mafai ona fa'aaogaina e fai ma sui ata tifaga, mafiafia, lubricant ma fa'apipi'i i aso uma pisinisi kemikolo, ma e mafai ona fa'aaogaina mo eruption, Moss, hair fixative gel, hair fixative, ma isi. Fa'aopoopoina le PVP i lauulu lauulu ma modifiers mo le tausiga o le pa'u, foam stabilizers mo shampoos, dispersants ma affinity agents e mafai ona faʻaleleia ai le la ma sui o le la. lubricating aafiaga. Lona lua, o le faʻaopoopoina o le PVP i le vailaʻau o loʻo i ai se aafiaga lelei o le lanu ma e mafai ona faʻaleleia ai le faʻamamaina.

Faʻaaogaina o le PVP i fale gaosi oloa ma tekonolosi: E mafai ona faʻaaogaina le PVP e fai ma sui faʻapipiʻi luga, faʻasalalau, mafiafia, ma faʻapipiʻi i pigments, inks lomitusi, textiles, lomitusi ma vali, ma faʻamalama ata lanu. E mafai e le PVP ona faʻaleleia le faʻaogaina o le faʻapipiʻi i uʻamea, tioata, palasitika ma isi mea. E le gata i lea, o le PVP o loʻo faʻateleina faʻaaogaina i le vavae ese, ultrafiltration membranes, microfiltration membranes, nanofiltration membranes, suʻesuʻega suauʻu, faʻamalo ata resins, vali ma coatings, Optical fiber, laser discs ma isi fanua faʻatekonolosi maualuga.

Faʻaaogaina o vailaʻau PVP: I totonu o le PVP-K faʻasologa, k30 o se tasi o mea faʻapipiʻi faʻaaogaina, aemaise lava mo gaosiga gaosiga, vailaʻau faʻapipiʻi mo granules, faʻamautu-faʻasaʻo sooupu, adjuvants ma stabilizers mo tui, fesoasoani tafe, dispersants mo vai formulations ma chromophores, presensitive mo fualaau faʻamaʻi, faʻamaʻi faʻamaʻi mo vailaʻau faʻamaʻi, faʻamaʻi faʻamaʻi mo vailaʻau faʻamaʻi, faʻamaʻi faʻamalosi mo vailaʻau faʻamaʻi, faʻamaʻi faʻamaʻi mo vailaʻau faʻamaʻi, faʻamaʻi faʻamaʻi mo vailaʻau faʻamaʻi, faʻamaʻi faʻamalosi mo vailaʻau. fa'alautele mo lubricants ophthalmic, ma mea e fa'apipi'i ai ata.

Polyvinylpyrrolidone ma ona polymers, e pei o mea fou kemikolo lelei, e masani ona faʻaaogaina i vailaʻau, meaʻai, vailaʻau i aso uma, lomitusi ma vali, faʻaofuofu pigmenti, mea olaola, mea e togafitia ai vai ma isi fanua, faʻatasi ai ma faʻamoemoega maketi lautele. I le maeʻa ai o tausaga o suʻesuʻega faʻaauau, ua matou atinaʻeina oloa faʻapipiʻi eseese, e aofia ai mea nei:

I se faapuupuuga, o le PVP faʻasologa o oloa e sili ona lelei le faʻatinoga ma e faʻaaogaina lautele e avea ma mea faʻapipiʻi polymer i vailaʻau, paʻu, pigments, resins, fiber inks, adhesives, detergents, textile lomitusi ma vali. PVP, e pei o se polymer surfactant, e mafai ona faʻaaogaina e avea o se dispersant, emulsifier, mafiafia, sui tulaga, viscosity regulator, anti reproduction suavai sui, coagulant, cosolvent, ma detergent i faiga taape eseese.
