pvp k30 yog dab tsi?
PVP-K30yog ib qho non-ionic polymer compound, uas yog ib qho kev kawm zoo thiab dav siv tshuaj zoo ntawm N-vinylamide polymers. Ntawm lawv, tus nqi K yog qhov ua tau zoo ntawm cov txheeb ze viscosity ntawm PVP aqueous tov. tus nqi.
PVP muab faib ua plaub qib raws li nws qhov nruab nrab qhov hnyav molecular, uas feem ntau yog sawv cev los ntawm tus nqi K, thiab qhov sib txawv K qhov tseem ceeb sawv cev rau qhov nruab nrab qhov hnyav molecular ntau ntawm PVP. Tus nqi K yog qhov tseeb tus yam ntxwv muaj feem cuam tshuam nrog cov txheeb ze viscosity ntawm PVP aqueous tov, thiab viscosity yog lub cev muaj nuj nqis ntsig txog qhov hnyav molecular ntawm cov polymer. Yog li ntawd, tus nqi K tuaj yeem siv los qhia qhov nruab nrab molecular hnyav ntawm PVP. Feem ntau, qhov loj dua tus nqi K, qhov viscosity ntau dua thiab muaj zog dua cov nplaum. K tus nqi ntawm polyvinylpyrrolidone yog 30, thiab nws cov tsos yog dawb los yog mis nyuj dawb hmoov los yog granule.

Kev siv PVP
1. Kev siv tshuaj thiab kev noj qab haus huv
Siv qhov zoo solubility, solubilization, physiological compatibility, thiab bonding peev xwm ntawm PVP, nws yuav siv tau raws li ib tug binder, excipient, txheej tshuab, solubilizer, zaj duab xis-forming tus neeg saib xyuas, thiab lwm yam. Feem ntau yog PVPK30 (Covidone K30), thiab nws qhov ntau npaum li cas nyob ntawm qhov yuav tsum tau muaj ntawm cov neeg kho tshuab lub zog ntawm cov tshuaj ntsiav tshuaj thiab cov khoom ntawm cov tshuaj nws tus kheej, feem ntau 0.5%-5%.
2. Daim ntawv thov hauv kev lag luam tshuaj txhua hnub
Ua kom zoo dua ntawm PVP (PVPK30 / PVPK90) qhov zoo tshaj plaws ntawm cov dej num, cov khoom ua yeeb yaj kiab thiab tsis muaj qhov khaus ntawm daim tawv nqaij, nws yog dav siv hauv kev lag luam tshuaj txhua hnub, tshwj xeeb tshaj yog cov tshuaj pleev ib ce, cov khoom tu tawv nqaij, tshuaj pleev ib ce thiab cov khoom siv tu. PVP yog tsuas yog siv rau emulsion Stabilization ntawm dispersion systems xws li, ncua kev kawm ntawv, thiab lwm yam., moisturizing thiab film-forming teebmeem nyob rau hauv cov khoom tu tawv nqaij. Kev ua haujlwm ntawm PVP hauv tshuaj txhua hnubCov khoom yog manifested nyob rau hauv cov nram qab no yam: 1. Dispersion thiab stability muaj nuj nqi, 2. Decontamination thiab ntxuav muaj nuj nqi, 3. film-forming thiab moisturizing muaj nuj nqi, 4. Sterilization thiab tshuaj tua kab mob muaj nuj nqi.
3. Kev siv hauv cov khoom siv hauv chaw ua haujlwm
(1) Kev siv PVP hauv tus cwj mem thiab tus cwj mem
PVP yog siv los ua tus cwj mem thiab tus cwj mem los ua kom cov ntawv sau thiab luam ntawv ruaj khov rau hauv daim ntawv tsis poob thiab ploj. Ntxiv mus, PVP muaj qhov cuam tshuam zoo thiab ruaj khov ntawm cov xim tsis muaj zog thiab cov xim organic dispersions. Nws tuaj yeem siv rau hauv inks thiab inks. Tau txais cov txheej txheem tsis sib xws, tsis yooj yim rau nag lossis daus, tsis clogging cwjmem thiab ntau lub nozzles, thiab cov ntawv sau tau zoo sib xws hauv qhov tob.
(2) Kev tsim cov ntaub ntawv
Kev tsim cov ntawv pov thawj yog pom tau los ntawm cov ntawv tshwj xeeb sib nqus. Qhov sib ntxiv ntawm PVP rau tus cwj mem tuaj yeem ua rau kom muaj kev ruaj ntseg ntawm cov barcode, thiab tsim ib qho yeeb yaj kiab barcode rau ntawm lub substrate, kom cov npoo ntawm barcode zoo huv si thiab ruaj khov thiab tsis yooj yim rau kev puas tsuaj.
(3) Kev siv PVP hauv ntawv
Hauv kev lag luam ntawv, PVP yog siv los txhim kho lub zog ntawm daim ntawv, solubilize roj thiab disperse pigments. Nws yog ib qho tseem ceeb pab tus neeg sawv cev hauv deinking ntawm cov ntawv pov tseg, decomposition ntawm rags, ntaus thiab xim. Thaum siv los ua cov txheej txheem, nws tuaj yeem txhim kho cov ntawv zoo. Zoo heev gloss, printability thiab roj kuj.
4. Daim ntawv thov hauv kev lag luam luam ntawv thiab dyeing
PVPK30 muaj kev sib raug zoo nrog cov organic dyes, thiab kev siv cov cuab yeej no ntawm PVP tuaj yeem ua rau muaj kev sib raug zoo ntawm qee cov hydrophobic fibers thiab dyes, yog li txhim kho cov dyeability ntawm cov fibers. Tsis tas li ntawd, nws tuaj yeem txhim kho nws cov hygroscopicity thiab kev tiv thaiv lub hnub, thiab txhim kho qhov zoo thiab qib ntawm cov hluavtaws fibers.
5. Lwm yam kev siv
PVP cov tshuaj coated rau ntawm cov noob tuaj yeem txo qhov kev puas tsuaj thaum lub sij hawm soaking thiab muaj peev xwm tiv thaiv kab mob lom.
PVP muaj qhov zoo adhesion rau iav, yas thiab hlau, thiab yog lub ntsiab tseem ceeb ntawm cov nplaum nplaum kub rau lub hom phiaj tshwj xeeb.
