O le a le Polyvinylpyrrolidone (PVP)

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 faʻaaogaina i vaega eseese e pei o vailaʻau, mea teuteu, meaʻai ma meainu, faʻavaʻa, ie, vavalaʻau vavae, ma isi. Faatasi ai ma le atinaʻeina o mea faʻasaienisi ma tekinolosi fou, ua faʻaaogaina le PVP i ia matata tekonolosi maualuga. e pei o resins curing ata, fibre Optical, tisiki leisa, toso faaitiitia mea, ma isi PVP ma mama eseese e mafai ona vaevaeina i ni togi se fa: vasega vailaau, vasega kemikolo i aso taitasi, vasega meaai, ma vasega 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 faʻaopoopoga o le solubility e faʻaititia 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 tulaga polymerization faagasologa eseese.

Matou te malamalama i le faagasologa o le PVP

Fa'agasologa-Tafe-ata

Fa'aaogāina ole PVP vasega tau alamanuia: PVP-K fa'asologa e mafai ona fa'aaogaina e fai ma sui o ata tifaga, mafiafia, lubricant ma fa'apipi'i i aso ta'itasi pisinisi fa'amalama, ma e mafai ona fa'aoga mo le pa, Moss, hair fixative gel, hair fixative, etc. ma suiga mo le tausiga o le pa'u, foam stabilizers mo shampoos, dispersants ma affinity agents mo galu styling agents, ma le kulimi ma le sunscreen e mafai ona faʻaleleia le susu ma le lubricating aafiaga. Lona lua, faʻaopoopo le PVP i le vailaʻau e iai se aafiaga lelei o le lanu 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.

pvp-fa'aoga

Faʻaaogaina o vailaʻau PVP: I totonu o le PVP-K faʻasologa, k30 o se tasi o mea faʻapipiʻi faʻaoga faʻaaogaina, aemaise lava mo le gaosiga o mea gaosi, mea faʻapipiʻi mo granules, faʻapipiʻi faʻamalolo, faʻapipiʻi ma faʻamautu mo tui, fesoasoani faʻafefe, faʻasalalau mo le faʻaogaina o vai. ma chromophores, faʻamautu mo enzymes ma vailaʻau faʻamaʻi vevela, mea faʻapipiʻi mo le faigata ona talia vailaʻau, faʻalautele mo lubricants ophthalmic, ma mea e faʻapipiʻi ata tifaga.

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:
