Polyvinylpyrrolidonetseem hu ua PVP, CAS naj npawb yog 9003-39-8. PVP yog cov khoom siv hluavtaws ua dej-soluble polymer uas yog polymerized los ntawmN-vinylpyrrolidone (NVP)nyob rau hauv tej yam kev mob. Nyob rau tib lub sijhawm, PVP muaj qhov zoo heev solubility, tshuaj ruaj khov, muaj peev xwm tsim cov yeeb yaj kiab, tsis muaj tshuaj lom, lub cev tsis muaj zog, nqus dej thiab muaj peev xwm moisturizing, muaj peev xwm sib txuas, thiab tiv thaiv cov nplaum nplaum. Nws tuaj yeem ua ke nrog ntau cov khoom siv tsis zoo thiab cov organic ua cov khoom siv ntxiv, cov khoom siv ntxiv, cov khoom siv pabcuam, thiab lwm yam.

Polyvinylpyrrolidone (PVP) tau ib txwm siv nyob rau hauv ntau yam xws li tshuaj, tshuaj pleev ib ce, khoom noj khoom haus thiab dej haus, brewing, textiles, sib cais daim nyias nyias, thiab lwm yam. Nrog rau txoj kev loj hlob ntawm tshiab scientific thiab technology khoom, PVP tau siv nyob rau hauv xws li high-tech teb. Raws li cov duab kho cov resins, Optical fiber, laser discs, luag cov khoom siv, thiab lwm yam. PVP nrog cov purities sib txawv tuaj yeem muab faib ua plaub qib: qib tshuaj, qib tshuaj txhua hnub, qib zaub mov, thiab qib kev lag luam.

Lub ntsiab yog vim li casPVPtuaj yeem siv ua co precipitant yog tias cov ligands hauv PVP molecules tuaj yeem ua ke nrog cov nquag hydrogen hauv cov molecules insoluble. Ntawm qhov tod tes, cov molecules me me dhau los ua amorphous thiab nkag mus rau PVP macromolecules. Ntawm qhov tod tes, hydrogen bonding tsis hloov cov dej solubility ntawm PVP, yog li qhov tshwm sim yog cov molecules insoluble dispersed nyob rau hauv pVp macromolecules los ntawm hydrogen bonding, ua rau lawv yooj yim rau yaj. Muaj ntau hom PVP, Peb yuav xaiv tus qauv li cas thaum xaiv. Thaum tus nqi (piv txwv li) ntawm PVP yog tib yam, qhov nce hauv solubility txo qis hauv qhov kev txiav txim ntawm PVP K15> PVP K30> PVP K90. Qhov no yog vim tias cov nyhuv solubilization ntawm PVP nws tus kheej hloov pauv hauv qhov kev txiav txim ntawm PVP K15> PVP K30> PVP K90. Feem ntau, pVp K 15 feem ntau siv.

Hais txog tiam ntawm PVP: tsuas yog NVP, ib tug monomer, koom nyob rau hauv lub polymerization, thiab nws cov khoom yog Polyvinylpyrrolidone (PVP). Lub NVP monomer tau txais tus kheej crosslinking cov tshuaj tiv thaiv los yog NVP monomer tau hla kev sib txuas copolymerization cov tshuaj tiv thaiv nrog tus neeg sawv cev crosslinking (muaj ntau cov pab pawg tsis txaus ntseeg), thiab nws cov khoom yog Polyvinylpyrrolidone (PVPP). Nws tuaj yeem pom tias ntau yam khoom siv polymerization tuaj yeem tsim los ntawm kev tswj cov txheej txheem sib txawv ntawm cov txheej txheem polymerization.

Peb nkag siab cov txheej txheem ntws ntawm PVP

Daim ntawv thov kev lag luam qib PVP: PVP-K series tuaj yeem siv los ua tus neeg saib xyuas zaj duab xis, thickener, lubricant thiab nplaum hauv kev lag luam tshuaj txhua hnub, thiab tuaj yeem siv rau kev tawg, Moss, plaub hau fixative gel, plaub hau fixative, thiab lwm yam. Ntxiv PVP rau cov plaub hau dyes thiab cov kev hloov kho rau kev tu tawv nqaij, ua npuas ncauj stabilizers rau cov tshuaj zawv plaub hau, cov tshuaj dispersants thiab cov neeg ua haujlwm sib raug zoo rau cov neeg ua haujlwm yoj styling, thiab cov tshuaj pleev thaiv hnub thiab tshuaj pleev thaiv hnub tuaj yeem txhim kho cov ntub dej thiab lubricating nyhuv. Qhov thib ob, ntxiv PVP rau cov tshuaj ntxuav tes muaj cov nyhuv zoo los tiv thaiv xim thiab tuaj yeem txhim kho lub peev xwm tu.

Daim ntawv thov ntawm PVP hauv kev lag luam thiab kev siv tshuab siab: PVP tuaj yeem siv los ua tus neeg sawv cev txheej txheej, dispersant, thickener, thiab nplaum nyob rau hauv cov xim, luam ntawv inks, textiles, luam ntawv thiab dyeing, thiab xim duab raj. PVP tuaj yeem txhim kho kev sib raug zoo ntawm cov nplaum rau hlau, iav, yas thiab lwm yam ntaub ntawv. Tsis tas li ntawd, PVP tau siv dav hauv kev sib cais membranes, ultrafiltration membranes, microfiltration membranes, nanofiltration membranes, roj kev tshawb fawb, yees duab kho resins, xim thiab txheej, Optical fiber, laser discs thiab lwm yam tshiab high-tech teb.

Daim ntawv thov ntawm cov tshuaj qib PVP: Ntawm cov PVP-K series, k30 yog ib qho ntawm cov khoom siv hluavtaws siv, feem ntau yog rau cov neeg ua haujlwm tsim khoom, cov neeg ua haujlwm nplaum rau cov granules, cov neeg ua haujlwm tso tawm, cov tshuaj tua kab mob thiab cov tshuaj stabilizers rau kev txhaj tshuaj, cov khoom siv ntws, dispersants rau cov kua formulations. thiab chromophores, stabilizers rau enzymes thiab thermosensitive tshuaj, co precipitants rau nyuaj rau zam tshuaj, extenders rau ophthalmic lubricants, thiab txheej film-forming agents.

Polyvinylpyrrolidone thiab nws cov polymers, raws li cov khoom siv tshuaj zoo tshiab, tau siv dav hauv tshuaj, khoom noj, tshuaj txhua hnub, luam ntawv thiab dyeing, xim txheej, cov khoom siv roj ntsha, cov ntaub ntawv kho dej thiab lwm yam, nrog rau kev lag luam dav dav. Tom qab xyoo ntawm kev tshawb nrhiav tas li, peb tau tsim ntau yam khoom sib sau ua ke, suav nrog cov hauv qab no:

Nyob rau hauv luv luv, PVP series ntawm cov khoom muaj kev ua tau zoo heev thiab yog dav siv raws li polymer additives nyob rau hauv cov tshuaj, coatings, pigments, resins, fiber inks, adhesives, detergents, textile printing thiab dyeing. PVP, raws li ib tug polymer surfactant, yuav siv tau raws li ib tug dispersant, emulsifier, thickener, leveling tus neeg saib xyuas, viscosity regulator, anti reproduction kua neeg sawv cev, coagulant, cosolvent, thiab detergent nyob rau hauv txawv dispersion systems.
