iindaba

Polyvinylpyrrolidoneikwabizwa ngokuba yiPVP, inombolo yeCAS yi-9003-39-8. I-PVP yikhompawundi yokwenziwa kwepolymer enyibilikayo ngokupheleleyo yamanzi eyenziwe ipholima ukusukaI-N-vinylpyrrolidone (NVP)phantsi kweemeko ezithile. Ngelo xesha, i-PVP ine-solubility egqwesileyo, ukuzinza kweekhemikhali, amandla okwenza ifilimu, i-toxicity ephantsi, i-inertness ye-physiological, i-absorption yamanzi kunye nokukwazi ukuthambisa, ukukwazi ukubopha, kunye nefuthe elikhuselayo lokunamathela. Inokudibanisa kunye neekhompawundi ezininzi ze-inorganic kunye ne-organic njengezongezo, izongezo, izinto ezincedisayo, njl.

I-Polyvinylpyrrolidone (PVP) isetyenziswe ngokwesiko kwiinkalo ezahlukeneyo ezifana neyeza, izithambiso, ukutya kunye nesiselo, ukutywala, iingubo, iimbumba zokuhlukana, njl. Ngokuphuhliswa kweemveliso ezintsha zenzululwazi kunye nezobuchwepheshe, i-PVP isetyenziswe kwiinkalo zobuchwepheshe obuphezulu. njenge-resin yokunyanga i-photo, i-fiber ye-Optical, i-laser discs, i-drag yokunciphisa izinto, njl. njl. I-PVP enezinto ezihlambulukileyo ezihlukeneyo zinokwahlulwa zibe ngamabakala amane: ibakala lamachiza, ibakala lemichiza yemihla ngemihla, ibakala lokutya, kunye nebakala lezoshishino.

Esona sizathu siphambiliI-PVPinokusetyenziswa njenge-co precipitant kukuba i-ligands kwii-molecule ze-PVP zinokudibanisa kunye ne-hydrogen esebenzayo kwiimolekyuli ezinganyibilikiyo. Kwelinye icala, iimolekyuli ezincinci ziba yi-amorphous kwaye zingena kwi-PVP macromolecules. Ngakolunye uhlangothi, i-hydrogen bonding ayitshintshi i-solubility yamanzi ye-PVP, ngoko ke umphumo kukuba iamolekyu ezingenakunyibilika zichithwa kwii-macromolecules ze-pVp ngokusebenzisa i-hydrogen bonding, okwenza kube lula ukunyibilika. Kukho iintlobo ezininzi zePVP, Sikhetha njani loo modeli xa ukhetha. Xa isixa (ubunzima) bePVP bufana, ukunyuka kwe-solubility kuncipha ngokomyalelo wePVP K15>PVP K30>PVP K90. Oku kungenxa yokuba umphumo we-solubilization we-PVP ngokwayo utshintsha ngokulandelelana kwe-PVP K15>PVP K30>PVP K90. Ngokubanzi, i-pVp K 15 isetyenziswa ngokuqhelekileyo.

Malunga nesizukulwana se-PVP: kuphela i-NVP, i-monomer, ithatha inxaxheba kwi-polymerization, kunye nemveliso yayo yi-Polyvinylpyrrolidone (PVP). I-monomer ye-NVP ifumana i-self crosslinking reaction okanye i-monomer ye-NVP ingena kwi-cross-linking copolymerization reaction kunye ne-agent ye-crosslinking (equlethe iikhompawundi zeqela ezininzi ezingaxutywanga), kwaye imveliso yayo yiPolyvinylpyrrolidone (PVPP). Ingabonwa ukuba iimveliso ezahlukeneyo zepolymerization zinokuveliswa ngokulawula iimeko ezahlukeneyo zenkqubo yepolymerization.

Siyayiqonda inkqubo yokuhamba kwePVP

Ukusetyenziswa kwe-PVP ye-industrial grade: i-PVP-K series ingasetyenziswa njenge-agent yefilimu, i-thickener, i-lubricant kunye ne-adhesive kumashishini ekhemikhali yemihla ngemihla, kwaye ingasetyenziselwa ukuqhuma, i-Moss, i-gel yokulungisa iinwele, i-hair fixative, njl. Ukongeza i-PVP kwiidayi zeenwele. kunye nezilungisi zokhathalelo lwesikhumba, izizinzisi zogwebu zeeshampu, ii-dispersants kunye ne-affinity agents for wave styling agents, kunye ne-cream kunye ne-sunscreen inokuphucula ukumanzisa kunye nefuthe lokuthambisa. Okwesibini, ukongeza i-PVP kwi-detergent kunesiphumo esihle sombala ochasene nombala kwaye kunokwandisa amandla okucoca.

Ukusetyenziswa kwe-PVP kwiinkalo zoshishino kunye nobuchwepheshe obuphezulu: I-PVP ingasetyenziselwa njenge-agent edibeneyo yokugqoka, i-dispersant, i-thickener, kunye ne-adhesive kwi-pigments, i-inki yokuprinta, i-textiles, ukuprinta kunye nokudaya, kunye neetyhubhu zemifanekiso yombala. I-PVP inokuphucula ukusebenza kwe-adhesive kwintsimbi, iglasi, iplastiki kunye nezinye izinto. Ukongezelela, i-PVP isetyenziswa ngokubanzi kwiimbumba zokwahlula, iimbumba ze-ultrafiltration, i-microfiltration membranes, i-nanofiltration membranes, i-oyile yokuhlola, i-resin yokunyanga ifoto, iipeyinti kunye neengubo, i-Optical fiber, i-laser discs kunye nezinye iindawo zobugcisa obuphezulu.

Ukusetyenziswa kwePVP yodidi lwamayeza: Phakathi koluhlu lwe-PVP-K, i-k30 yenye yezinto zokwenziwa ezisetyenziswayo, ngokukodwa kwii-arhente zemveliso, i-adhesive agents for granules, i-agent-release-release agents, i-adjuvants kunye ne-stabilizers yezitofu, i-flow aids, i-dispersants for formulations kunye nechromophores, izinzisi for enzymes kunye neziyobisi thermosensitive, co precipitants kuba nzima ukunyamezela iziyobisi, extender for ophthalmic lubricants, kunye nokugquma ii-agent ezenza ifilimu.

I-Polyvinylpyrrolidone kunye neepolymers zayo, njengezinto ezintsha zeekhemikhali ezintle, zisetyenziswa kakhulu kumayeza, ukutya, iikhemikhali zemihla ngemihla, ukuprinta kunye nokudaya, iingubo ze-pigment, izinto zebhayoloji, izinto zokucocwa kwamanzi kunye nezinye iindawo, kunye nethemba lokusetyenziswa kweemarike ngokubanzi. Emva kweminyaka yophononongo oluqhubekayo, siye savelisa iimveliso ezahlukeneyo zokudibanisa, kuquka nezi zilandelayo:

Ngamafutshane, uluhlu lweemveliso zePVP zisebenza kakuhle kwaye zisetyenziswa ngokubanzi njengezongezo zepolymer kumayeza, iingubo, ii-pigments, iiresini, i-fiber inki, i-adhesives, i-detergents, i-textile printing kunye nokudaya. I-PVP, njenge-polymer surfactant, inokusetyenziswa njenge-dispersant, i-emulsifier, i-thickener, i-agent yokulinganisa, i-viscosity regulator, i-anti reproduction agent engamanzi, i-coagulant, i-cosolvent, kunye ne-detergent kwiinkqubo ezahlukeneyo zokusasazeka.
