Polyvinylpyrrolidoneinonziwo PVP, nhamba yeCAS i9003-39-8. PVP ndeye yakanyatsogadzirwa mvura-inonyungudika polima mukomboni uyo wakagadzirwa nepolymerized kubvaN-vinylpyrrolidone (NVP)pasi pemamwe mamiriro. Panguva imwecheteyo, PVP ine yakanakisa solubility, kugadzikana kwekemikari, kugona kugadzira firimu, kuderera kwehuturu, physiological inertness, kunyudza mvura uye kugona kunyorova, kugona kwekubatanidza, uye inodzivirira inonamatira maitiro. Inogona kusanganisa neakawanda inorganic uye organic komisheni sezvinowedzera, zvekuwedzera, zvekubatsira zvinhu, nezvimwe.
Polyvinylpyrrolidone (PVP) yagara ichishandiswa munzvimbo dzakasiyana siyana semushonga, zvizorwa, chikafu nechinwiwa, kubika, machira, kupatsanurwa membrane, nezvimwe. Nekuvandudzwa kwezvigadzirwa zvitsva zvesainzi uye tekinoroji, PVP yakashandiswa munzvimbo dzakadai dzepamusoro-soro. sezvo mufananidzo kurapa resin, Optical faibha, Laser discs, achikweva kuderedza zvinhu, etc. PVP pamwe siyana purities inogona kukamurwa giredhi mana: mishonga giredhi, zuva nezuva kemikari giredhi, zvokudya giredhi, uye maindasitiri giredhi.
Chikonzero chikuru neiPVPinogona kushandiswa se co precipitant ndeyekuti ligands muPVP mamorekuru anogona kusangana neanoshanda haidrojeni mumamorekuru asinganyunguriki. Kune rimwe divi, mamorekuru madiki anova amorphous uye anopinda PVP macromolecules. Kune rumwe rutivi, hydrogen bonding haichinje kunyungudika kwemvura kwePVP, saka mhedzisiro ndeyekuti mamorekuru asina kunyungudika anoparadzirwa mupVp macromolecules kuburikidza nehydrogen bonding, zvichiita kuti zvive nyore kunyungudika. Kune akawanda marudzi ePVP, Isu tinosarudza sei iyo modhi pakusarudza. Kana huwandu (hukuru) hwePVP hwakafanana, kuwedzera kwekunyungudika kunoderera mukurongeka kwePVP K15>PVP K30>PVP K90. Izvi zvinodaro nekuti iyo solubilization mhedzisiro yePVP pachayo inoshanduka mukurongeka kwePVP K15>PVP K30>PVP K90. Kazhinji, pVp K 15 inonyanya kushandiswa.
Nezve chizvarwa chePVP: chete NVP, monomer, inotora chikamu mu polymerization, uye chigadzirwa chayo Polyvinylpyrrolidone (PVP). Iyo NVP monomer inopinda self crosslinking reaction kana iyo NVP monomer inopinda muchinjika-inobatanidza copolymerization reaction neiyo crosslinking agent (ine akawanda unsaturated boka makomboni), uye chigadzirwa chayo Polyvinylpyrrolidone (PVPP). Zvinogona kuoneka kuti akasiyana polymerization zvigadzirwa zvinogona kugadzirwa nekudzora akasiyana polymerization process mamiriro.
Isu tinonzwisisa mafambiro ePVP
Kushandiswa kwemaindasitiri giredhi PVP: PVP-K yakatevedzana inogona kushandiswa semumiriri wemufirimu, thickener, lubricant uye anonamira muindasitiri yemakemikari yemazuva ese, uye inogona kushandiswa kuputika, Moss, bvudzi rinogadzirisa gel, bvudzi rinogadzirisa, etc. Kuwedzera PVP kune bvudzi dhayi. uye zvinogadziridza zvekuchengetedza ganda, foam stabilizers ye shampoos, dispersants uye affinity ejenti yeave styling agents, uye kune cream uye sunscreen inogona kuwedzera kunyorova uye kudzosa. Kechipiri, kuwedzera PVP kune detergent kune yakanaka anti color mhedzisiro uye inogona kuwedzera kugona kwekuchenesa.
Kushandiswa kwePVP mumaindasitiri uye epamusoro-tekinoroji minda: PVP inogona kushandiswa seyepamusoro coating agent, dispersant, thickener, uye inonamira mu pigment, inki dzekudhinda, machira, kudhinda uye dhayi, uye mavara emifananidzo machubhu. PVP inogona kuvandudza kushanda kwechisungo chekunamatira kune simbi, girazi, plastiki uye zvimwe zvinhu. Uye zvakare, PVP iri kuwedzera kushandiswa zvakanyanya mukuparadzanisa membranes, ultrafiltration membranes, microfiltration membranes, nanofiltration membranes, mafuta ekuongorora, mafoto ekurapa resin, pendi uye machira, Optical fiber, laser discs uye mamwe ari kubuda epamusoro-tech minda.
Kushandiswa kwegiredhi remishonga PVP: Pakati pePVP-K yakatevedzana, k30 ndeimwe yezvakagadzirwa excipients inoshandiswa, kunyanya kune zvigadzirwa zvekugadzira, zvinonamira maajenti emagranules, anosimudzira-kuburitsa maajenti, adjuvants uye stabilizers emajekiseni, kuyerera aids, dispersants for liquid formulations. uye chromophores, stabilizers for enzymes uye thermosensitive drugs, co precipitants for yakaoma kushivirira zvinodhaka, extender for ophthalmic lubricant, uye coating film-forming agents.
Polyvinylpyrrolidone nemapolymers ayo, semidziyo mitsva yakanaka yemakemikari, anoshandiswa zvakanyanya mumishonga, chikafu, makemikari ezuva nezuva, kudhinda uye dhayi, pigment coatings, biological materials, mvura yekuchenesa mvura nemimwe minda, ine tarisiro yekushandiswa kwemusika wakafara. Mushure memakore ekuenderera mberi kwekuongorora, takagadzira zvigadzirwa zvakasiyana-siyana zvekuunganidza, kusanganisira zvinotevera:
