Chii chinonzi Polyvinylpyrrolidone (PVP)?
Polyvinylpyrrolidone, yakapfupikiswa sePVP. Inoshandiswa sechinhu chinobatsira, chinowedzera, uye chinobatsira muminda yakawanda yakadai semushonga, machira, makemikari, zvinwiwa, uye makemikari ezuva nezuva. Zvichienderana nezvinodiwa nechigadzirwa, PVP inogona kukamurwa kuita mhando ina: giredhi reindasitiri, giredhi rezvizoro, giredhi rechikafu, uye giredhi remishonga. Homopolymers, copolymers, uye cross-linked polymer series zvigadzirwa zvine huremu hwemamorekuru hunotangira pazviuru kusvika pamiriyoni imwe zvave zvichishandiswa zvakanyanya nekuda kwehunhu hwazvo hwakanaka uye hwakasiyana.
PVP yakakamurwa kuita mazinga mana zvichienderana nehuremu hwayo hwemamorekuru, uye inowanzomiririrwa neK values. K values dzakasiyana dzinomiririra huwandu hunoenderana hwehuremu hwemamorekuru hwePVP. K value chaizvoizvo hunhu hunoenderana nehuremu hwePVP, uye viscosity huwandu hunoenderana nehuremu hwemamorekuru emapolymers. Nokudaro, K value inogona kushandiswa kuratidza huremu hwemamorekuru hwePVP. Kazhinji, K value yakakura, viscosity yayo inowedzera uye inonamira yakasimba. Mhando huru dzezvigadzirwa uye zvirevo zvePVP zvinogona kupatsanurwa mumazinga eviscosity eK-15, K17, K25, K-30, K60, uye K-90 zvichienderana nehuremu hwemamorekuru.

PVP, semusanganiswa wepolymer unonyungudika mumvura, une hunhu hwezvinhu zvepolymer zvinonyungudika mumvura, zvinosanganisira kudzivirira colloid, kugadzira firimu, kubatana, kunyungudika kwehunyoro, kunyungudika kana kuonda. Zvisinei, chinhu chayo chinonyanya kusiyanisa kunyungudika kwayo kwakanaka uye kuenderana kwemuviri, izvo zvakakwezva kutariswa. Mumapolymer ekugadzira, PVP, inonyungudika mumvura uye mune zvakawanda zvinonyungudika zve organic, ine chepfu shoma, uye inoenderana zvakanaka nemuviri, haiwanzoonekwa, kunyanya munzvimbo dzine chekuita nehutano hwevanhu dzakadai semishonga, chikafu, uye zvizoro. Izvi zvinotevera sumo chaiyo yenzvimbo dzayo dzekushandiswa:
Mumunda wezvizoro zvezuva nezuva
Muzvizoro zvezuva nezuva, PVP ne copolymer zvine simba rekupararira zvakanaka uye kugadzira firimu. PVP inogona kuchengetedza colloid mu lotion, uye inogona kushandiswa mumakirimu ane mafuta neasiri mafuta, se setting liquid, hair spray ne mousse setting agent, hair conditioner ne sunscreen, shampoo foam stabilizer, wave setting agent, uye hair dye dispersant uye affinity agent. Kuwedzera PVP mu snow cream, sunscreen, uye hair removal agents kunogona kuwedzera mhedzisiro yekunyorovesa nemafuta.
Munda wekuwachisa

Kudhinda nekudhaya machira
PVP ine hukama hwakanaka nemadhayi akawanda eorganic uye inogona kusanganiswa nemafiber ekugadzira asina kunyungudika akadai sepolyacrylonitrile, esters, nylon, uye zvinhu zve fibrous kuti ivandudze simba rekudhaya uye hydrophilicity. Mushure mePVP ne nylon grafting copolymerization, jira rakagadzirwa rakavandudza kusimba kwaro kwehunyoro uye kusimba kwehunyoro.
Kupfeka uye pigments
Pendi nependi dzakaputirwa nePVP zvinoonekera pasina kukanganisa ruvara rwazvo rwechisikigo, zvichivandudza kupenya nekupararira kwependi nepigment, zvichiwedzera kugadzikana kwekupisa, uye zvichivandudza kupararira kweinki neinki.
Munda wezvekurapa
PVP ine kusagadzikana kwakanaka kwemuviri, haibatanidzi mukugadzirwa kwemuviri kwevanhu, uye inoenderana zvakanyanya nehupenyu, iyo isingakonzere kushatirwa paganda, mucosa, maziso, nezvimwewo. PVP yemhando yekurapa ndeimwe yezvinhu zvitatu zvikuru zvinoshandiswa mumishonga zvinokurudzirwa pasi rese, iyo inogona kushandiswa sechinobatanidza mapiritsi nemagranules, chinhu chinonyungudutsa chejekiseni, uye chinhu chinobatsira pakuyerera kwemakapisi; Zvinobvisa chepfu, zvinowedzera, mafuta uye zvinogadzira mafirimu emadonhwe emaziso, zvinoparadzanisa maformula emvura, zvinosimbisa maenzyme nemishonga inodziya, uye zvinogona kushandiswawo sezvinodzivirira zvinopisa zvishoma. Inoshandiswa kumalenzi ekuona kuti awedzere hydrophilicity uye lubricity. Pamusoro pezvo, PVP inogona zvakare kushandiswa semushonga wekupenda uye X-ray contrast; Inogona kushandiswa pamhando dzakasiyana dzemishonga dzakadai semapiritsi, magranules, nemvura. Ine detoxification, hemostasis, kuwedzera kuwanda kwekunyungudika, kudzivirira kunamatira kweperitoneal, uye kukurudzira erythrocyte sedimentation rate. PVP K30 yakatangwa zviri pamutemo nekubvumidzwa nedhipatimendi renyika rezvemishonga.
Kugadzira chikafu
PVP pachayo haina kukonzera kenza uye ine kuchengetedzeka kwakanaka kwechikafu. Inogona kugadzira macomplexes ane mapolyphenolic compounds chaiwo (akadai se tannins) uye inonyanya kushandiswa sechinhu chinojekesa uye chinodzikamisa mukugadzira chikafu, senge doro, muto wemichero, newaini. PVP inogona kugadzira macomplexes ane mapolyphenolic compounds chaiwo (akadai se tannins), ayo anoita basa rekujekesa uye rekudzivirira ropa muzvinwiwa zvemuchero. Kushandiswa kwe cross-linked PVP muzvinwiwa zvedoro netii kwakanyanya kupararira. Zvinhu zvepolyphenolic mudoro zvinogona kubatana nemapuroteni mudoro kuti zvigadzire tannin macromolecular complexes, izvo zvinokanganisa zvakanyanya kunaka kwedoro uye kupfupisa hupenyu hwaro hwesherufu. Crosslinked polyvinylpyrrolidone (PVPP) inogona chelate ne tannic acid uye anthocyanins mudoro, nokudaro ichijekesa doro, ichivandudza kugadzikana kwaro mukuchengetedza, uye kuwedzera hupenyu hwaro hwesherufu. Muzvinwiwa zvetii, kushandiswa kwePVPP kunogona kuderedza zviri mukati metii polyphenols, uye PVPP haigari muzvinwiwa zvetii, zvichiita kuti ishandiswezve uye inoderedza mari yakawanda.
Nzvimbo huru dzekushandisa PVP parizvino dzakanyanya kuunganidzwa mumaindasitiri emishonga nemakemikari ezuva nezuva, uye kukura kwemaindasitiri maviri aya kucharamba kuchikurudzira kudiwa kukuru kwekushandiswa kwePVP mune ramangwana. Mundima iri kubuda yePVP, muindasitiri yemabheteri e lithium, PVP inogona kushandiswa semuchina wekuparadzanisa maerekitironi ebhatiri re lithium uye mubatsiri wekugadzirisa zvinhu zvinofambisa magetsi; Muindasitiri ye photovoltaic, PVP inogona kushandiswa semuchina wekuparadzanisa kugadzira hupfu hwesirivha hwemhando yepamusoro hwe positive electrode silver paste, hupfu hwesirivha hwakaita sepepa re negative electrode silver paste, uye nano silver particles. Nekuvandudzika kuri kuramba kuchienderera mberi kwehuwandu hwekupinda kwebhatiri re lithium uye kuwedzera kwesimba re photovoltaic rakaiswa, minda miviri iyi iri kubuda ichasimudzira zvakanyanya kudiwa kwePVP.
Unilong mutengesi ane hunyanzvi, uyePVP nhevedzanoyave ichigadzirwa kwemakore gumi. Nekuchinja kuri kuita musika, kuwanikwa kwezvigadzirwa zvePVP kuri kushomeka. Parizvino, tawedzera mimwe migwagwa miviri yekugadzira, ine kuwanikwa kwakakwana uye mitengo yakanaka. Ndapota inzwa wakasununguka kubvunza.
