Kev sib koom ua ke ntawm cov khoom siv cov duab kos tau hloov kho cov kev coj ua, tab sis ua kom pom cov nruab nrab ntawm polymers thiab cov kuab tshuaj nruab nrab tseem ceeb heev.Hangzhou Zaj sawv ntshuam & Export Co., Ltd.,Ib qho khoom siv rau cov khoom lag luam ntawm cov kev daws teeb meem zoo, tau tsim khoNvp homopolymers(polyvinylprolidone, pvp) uas hais txog qhov teeb meem no. NVP homopolers, muaj tshuaj lom neeg tshwj xeeb, muaj cov kws ua yeeb yam zoo rau kev txhim kho kev ruaj khov, thiab kev ua tau zoo hauv cov txheej txheem txheej txheem nruab nrab. Kab lus no tshawb txog nvp homopalymers nrog cov tshuaj kos duab, txhawb los ntawm kev tso duab txuj ci thiab cov khoom tshiab ntawm zaj sawv ntawm cov khoom lag luam tshiab.
To taub cov nvp homopolymers
Cov qauv tshuaj thiab cov khoom
Nvp homopolers, xws lipolyvinylprolidone (pvp), yog cov hluavtaws polymers tsim los ntawm cov polymerization ntawm n-vinylpyrrolidone monomers. Lawv cov qauv nta apyrrolidone nplhaibthiab kab nraub qaum, muab rau lawvsiab polaritythiabZoo heev hydrogen-bonding muaj peev xwmCov. Cov khoom no pab tau nvp homopolers kom yaj nyob rau hauv ntau cov organic cov kuab tshuaj, tshuaj muaj dej, thaum tswjfab ruaj khov hauv cov khoom tsis muaj zog hauv nruab nrab.
Zaj sawv lubSunlydone® K Series(piv txwv li, K15, K30, K90) muaj cov hnyav txiav molecular kom ua tau raws li cov kos duab sib txawv. Piv txwv li,K30(MW ~ 40, {{000}) muab cov solubility thiab viscosity tswj, ua rau nws zoo tagnrho rau cov xim tsev thiab inks.
Mechanism ntawm kev ua nyob rau hauv cov tshuab xyaum-raws li
Hauv cov kuab tshuaj-raws cov qauv nruab nrab, nvp homopolers ua los ntawmStaper Ruaj Khovthiabkev sib xyaw ua ke:
Staper Ruaj Khov: Polymer chains tsim ib txheej tiv thaiv ib ncig ntawm cov xim xim, tiv thaiv kev sib sau ua ke thiab ua kom muaj kev sib cais sib txawv.
Kev sib xyaw ua ke: Cov pyrrolidone rings nyob rau hauv nvp homopolymers tsim muaj zog hydrogen sib khi nrog cov kuab tshuaj me thiab substrate chaw, txhim kho cov khoom zoo nkauj thiab ua yeeb yaj kiab.
Zaj sawv lubSunlydone® VA series(PVP \/ VA copolymers) txuas ntxiv ua kom zoo sib xws hauv cov tshuab ntsuas hydrophilic thiab cov ntu khov kho txawm tias muaj cov qauv sib luag.
Qhov tseem ceeb cuam tshuam compatibility
Kaus hom thiab polarity
Qhov sib raug zoo ntawm nvp homopolers nrog cov kuab tshuaj yog nyob ntawm lawvthaj yeebthiabHnyav zog:
Cov lus qhia loj polar(piv txwv li, dej cawv, ketones): nv hompolymers yaj tau yooj yim, ua cov kev daws teeb meem. Piv txwv li,Sunlydone® K15(Tsis muaj MW) yaj tau sai sai nyob rau hauv ethanol, ua rau nws haum rau kev ziab cov inks-.
Tsis-Qib Polvents(xws li, ntxhia ntsuj plig, turpentine): qib siab pololecular qib zoo liK90yog qhov zoo tshaj plaws, raws li lawv cov kev sib tw ntev ntev ua solubility thiab zaj duab xis nyob rau hauv tsis-ncej puab ib cheeb tsam.
Zaj sawv cov ntaub ntawv cov ntaub ntawv muab cov ncauj lus kom ntxaws solubility solubility solubility solvents solubents dolvents, kom cov neeg siv kom tau xaiv cov khoom zoo rau lawv qhov nruab nrab.
Concentration thiab viscosity tswj
Qhov zoo tshaj plaws concentration ntawm nvp homopolers sib txawv raws li cov khoom xav ua haujlwm:
Tsawg ntau (< 1% w/w): Suitable for low-viscosity applications like inkjet inks, where minimal thickening is required.
Nruab nrab Ntau(1-3% w \/ w \/ w): Qhov zoo tagnrho rau cov txheej txheem thiab xim pleev xim, ntsuas kev faib khoom ruaj khov thiab ua haujlwm.
High aus (>3% w \/ w \/ w): Siv cov qauv tsim muaj txiaj ntsig los tiv thaiv kom tsis txhob muaj kev ua kom pom tseeb, txawm tias qhov no yuav ua pa viscosity thiab yuav tsum tau xaws-thinning ntxiv.
Zaj sawv lubSunlydone® K30ntawm 1.5% w \/ w tau pom tias yuav muaj viscosity los ntawm30%Hauv kev ncua ntawv ti₂ thaum tswj lub sijhawm ntev ruaj khov.
Kev cuam tshuam nrog cov xim thiab ntxiv
Nvp homopolymers cuam tshuam nrog cov pigments thiab ntxiv ntxiv:
Xim Xim: Nvp homopolers adsorb mus rau cov xim xim, txo cov npoo nro thiab txhim kho kev ntub dej. Piv txwv li,Sunlydone® K90txhim kho kev faib tawm ntawm phthalocyanine xiav xiav hauv cov inks, ua tiav98% xim sib xwshla kev.
Additive Compatibility: Nvp homopolymers tau sib haum nrog cov txheej txheem nruab nrab hauv nruab nrab, xws li cov tsav tsheb hauv nruab nrab, UV Stabilizers, thiab cov yas, tsis muaj kev ua tau zoo.
