Hauv daim ntawv thov cov xim pigment, kev xaiv ntawm cov siab - molecular polymers ncaj qha cuam tshuam rau cov teebmeem xim, kev ruaj khov, thiab cov txheej txheem hloov tau. Raws li kev lag luam muag khoom, Hangzhou Zaj sawv Ntshuam & Export Co., Ltd. Tau tsom rau R & D thiab ntau lawmN - vinylprolidone (NVP)Cov khoom lag luam, npog ob pawg tseem ceeb:Homopolers (NVP Homopolymers)thiabpolyvinylprolidone (pvp)Cov. Cov kab lus no ntsuas qhov sib txawv tseem ceeb ntawm ob los ntawm qhov ntev xws li tshuaj lom neeg, ua haujlwm rau cov kws tshaj lij kev lag luam rau cov kws kho mob ua lag luam.
Qhov sib txawv hauv cov qauv tshuaj thiab khoom siv hluavtaws
Nvp homopolymers
NVP homopolymers tau tsim los ntawm free {{0} radical polymerization ntawm ib lub nplhaib pyrrolidone (nrog tsuas yog pyrrolidone ntiv nplhaib hauv cov molecular. Lawv cov synthesis siv cov tshuaj polymerization, tswj cov roj molecular, kub thiab pib ua kom cov txheej txheem nqaim thiab cov txheej txheem siab.
PVP (polyvinylprolidone)
PVP kuj siv NVP los ua cov monomer tab sis cov ntaub ntawv ib qho ntxiv cov molecular network los ntawm copolymerization lossis hla}}}}}}}}}}}}}}}}}} ntawv txuas. Muab faib ua ke los ntawm kev ua haujlwm hnyav, PVP tau muab faib ua hom K15, K60, K60, K90, thiab lwm yam. Cov siab dua cov molecular hnyav, thiab cov nplaum. Hauv kev lag luam ntau lawm, PVP feem ntau cov haujlwm feem ntau cov kev ua haujlwm polymerization lossis thooj polymerization nruj, uas xav tau kev tswj nruj ua haujlwm kom tsis txhob muaj kev tswj nruj thiab tsis muaj kev tswj hwm.
Qhov tseem ceeb sib txawv: Nvp homopolers muaj cov qauv kab, thaum PvP tej zaum yuav muaj cov kab lossis hla kev sib txawv hauv cov qauv sib txuam thiab cov khoom siv lub cev.
Kev sib piv ntawm cov khoom siv lub cev
Solubility thiab viscosity
NVP cov homopolymers nthuav tawm solubility nyob rau hauv cov kuab tshuaj polar, ua rau lawv tsim nyog ua cov tshuaj tsis huv. Lub solubility ntawm pvp tsawg zuj zus nrog nce k nqi; Siab - k hom (piv txwv li, k90) daim ntawv siab- voscosos yuav tsum muaj cov xwm txheej muaj zog.
Thermal ruaj khov
NVP homopolymers muaj cov tsis muaj zog thermal stability, nquag {{{0} {{0} -} kub txheej txheem. Lub thermal stability ntawm pvp txhim kho nrog phaus molecular; Hom K90 tuaj yeem tiv taus kub siab dua 200 degree, haum rau high- kub kho txheej tshuab.
Hygroscopicity
NVP homopolymers muaj kev hygroscopicity muaj zog, uas tuaj yeem cuam tshuam xim cov chaw tso cai ruaj khov hauv ib puag ncig vaum. PVP tau qis dua hygroscopicity, tshwj xeeb tshaj yog nyob rau hauv high- hom ntawv siv sab nraum zoov lossis siab}} noo noo ib puag ncig.
Xim Dispersion thiab Kev Ruaj Ntseg Ua Haujlwm
Txau Zog
PvP, nrog nws amphipilic qauv (pyrrolidone nplhaib thiab vinyl chanment, ua rau muaj kev sib txuas lus saum npoo av ntawm cov khoom sib txuas thiab tiv thaiv flocculation thiab kev ua yeeb yaj kiab. Piv txwv li, ntxiv pvp - k30 rau inks tuaj yeem txhim kho cov xim tsis muaj peev xwm tshaj 6 lub hlis, nrog tsawg li nozzle thaiv.
NVP homopolymers muaj lub peev xwm tsis muaj zog, ntau dua siv ua cov dispersants hauv kev sib xyaw ua ke nrog lwm cov surfactants lossis hauv cov txheej txheem yooj yim nrog qis dua kev tshaj tawm.
Anti -} sedimentation
PVP sau cov txheej txheem colloidal ruaj khov hauv dej - Raws li cov xim xim, muaj ntau lub qe xim sedimentation. Piv txwv li, ntxiv pvp - k60 k60 rau cov xim tsev zoo tuaj yeem ua kom muaj kev nyab xeeb xim tshaj 30%.
Vim tias tsis muaj cov pab pawg ua kom muaj zog tshaj tawm, NVP homopolymers muaj cov tshuaj tiv thaiv tsis muaj zog thiab yuav tsum tau siv nrog cov kev ruaj khov.
Zaj duab xis - sib sau cov khoom thiab cov adhesion
Film -} Ua cov yam ntxwv
PVP cov qauv pob tshab, cov yeeb yaj kiab niaj hnub thaum ua kom qhuav, txhim kho cov ci ci thiab hnav tsis kam ntawm cov xim pleev xim. Piv txwv li, ntxiv pvp - k90 rau txheej ci tuaj yeem ua kom zaj duab xis nyuaj los ntawm 20% thaum ua kom muaj kev tswj tau zoo.
NVP Homopolymers muaj cov yeeb yaj kiab tsis muaj zog {0} Nyeem cov khoom viscosity, feem ntau siv los ua kev sib xyaw nrog lwm cov nyiaj los txhim kho zaj duab xis kom txhim kho zaj duab xis kom txhim kho zaj duab xis.
Kua nplaum
Cov pyrrolidone rings nyob rau hauv nvp homopolymer molecular charts tuaj yeem tsim cov khoom siv hydrogen nrog cov txheej txheej av, txhim kho txheej adhesion. Piv txwv li, ntxiv nvp homopolers rau hlau cov txheej txheem tuaj yeem txhim kho adhesion mus rau qib 0 (ISO 2409 txuj ci).
PVP Adhesion nyob ntawm molecular phaus thiab hla -} kev sib txuas; high - k}} K-} K-} K-} K-} K-} Ko} Substrates (piv txwv li, iav, yas) tab sis qhia cov chaw tsis muaj zog ntawm qhov chaw.
Tus nqi thiab kev txiav txim siab ib puag ncig
Cov nqi ntau lawm
Cov txheej txheem synthesis ntawm nvp homopolymers yog qhov yooj yim nrog cov khoom siv raw qis, haum rau loj {{0} teev ntau lawm. PVP muaj cov nqi tsim ntau dua vim tias yuav tsum tau tswj cov nqi hluav taws xob molecular, tshwj xeeb nrog cov nqi them rov qab rau cov qib thiab qib hluav taws xob.
Hangzhou Zaj sawv txoj kev ua haujlwm zoo dua: Lub tuam txhab siv cov txheej txheem catalytic hydrogenic tshiab los ntawm 20%, thiab cov khoom siv tau los ntawm 15%, thiab txhim kho kev ua lag luam kev sib tw.
Ib puag ncig ua phooj ywg
NVP Homopolymers yog biodegradable, ua raws li EU cuag cov kev cai rau ib puag ncig cov ntaub ntawv ua phooj ywg. PVP muaj cov tsis muaj txiaj ntsig, tab sis ua kom zoo rau cov txheej txheem polymerization (piv txwv li, siv dej}
Tuam txhab coj: Hangzhou Zaj sawv lub PVP cov kab ntau lawm yog GMP {{} Daim ntawv pov thawj ua tiav, tau txais kev lees paub rau FDA thiab EU Tshuaj pleev ib ce cov cai.
