Hauv cov liaj teb xws li txheej, inks, thiab cov tshuaj pleev ib ce, tshem tawm cov txiaj ntsig ntawm cov xim sib xws, kev ua kom muaj cov khoom lag luam, thiab ua kom zoo kawg. Raws li tus tseem ceeb additive,NVP (n - vinylprolidone) Homopolymerstau dhau los ua cov ntaub ntawv tseem ceeb rau kev ua kom zoo ntawm cov kab mob rheological ntawm cov qauv molecular thiab cov khoom siv mileicemical. Ua ke cov kev coj ua ntawm Hangzhou Zaj sawv Ntshuam ntshuam & Export Co., Ltd.
Cov yam ntxwv yooj yim thiab muaj nqi ntawm nvp homopolymers
NVP homopolymers, namely polyvinylprolidrury (pvp), yog linear polymerization formed los ntawm dawb radical polymerization ntawm n} vinylpyrrolidone monomers. Cov Pyrrolidone Rings hauv lub molecular charting zoo heev hydraulic muaj peev xwm muaj peev xwm thiab cov vinyl qauv muab tshuaj zoo thiab cov dej solubility. Qhov tshwj xeeb no qauv molecular muab nvp homopolymers irreplaceable zoo nyob rau hauv ntau daim teb:
Siab polarity thiab dej solubility: Tsis pub lwm tus nrog cov kuab tshuaj polar xws li dej thiab dej cawv, haum rau dej - raws xim cov tshuab.
Muaj peev xwm nyuaj: Pyrrolidone Rings tuaj yeem tsim cov complexes nrog hydroxyl, carboxyl, thiab lwm pab pawg ntawm cov xim xim, txhim kho kev sib cais.
Zaj duab xis - sib sau thiab cov khoom nplaum: Ua ib qho yeeb yaj kiab niaj hnub thaum ziab, txhim kho txheej nplaum thiab ruaj khov.
Raws li ib tug coj pvp chaw tsim tshuaj paus hauv Suav teb, Hangzhou Zaj sawv Ntshuam ntshuam & Export Co., Ltd. YEEM Nws GMP - Daim ntawv pov thawj cov kab ua kom muaj peev xwm siab (ntau dua lossis sib npaug
Cov Cuam Tshuam Cov Txheej Txheem Ntawm NVP homopolymers ntawm pigment muab cov rheology
Viscosity Tshooj:Dynamic teb los ntawm tsawg kawg shear
Lub viscosity ntawm cov pastiscosity yuav tsum tshuav kev sib npaug - sedimentation thaum lub sijhawm khaws cia zoo li qub thiab kua txiv thaum lub sijhawm applicate. Nvp homopolymers tau ua tiav cov kev cai los ntawm cov txheej txheem nram qab no:
Thickening nyhuv: High {{- molecular {{} 90, k020, K90, K90, K90, K9Chessly Ua kom muaj kev sib txhuam sab hauv ntawm cov nqi sib tw tsawg. Piv txwv li, ntxiv 0.5 {- 2% rau cov txheej txheem dej ua kom muaj 200 mpaMau.
Shear -} cov nplaig: Under High Shear tej yam kev mob (piv txwv li, thaum lub sij hawm txheej), pvp molecular chains disitangle, thiab viscosity kom tsawg dua kom ntseeg tau tias zoo heev fluidity thiab cov txheej txheem sib dhos. Qhov no "shear- nkuag" cov cuab yeej ua kom zoo heev daim ntawv thov kev xav tau ntawm cov xim pases.
Molecular qhov kev cia siab hnyav: Hangzhou Zaj sawv lub PvP k series cov khoom (piv txwv, k60 k60) tso cai hloov tau dav dav. Piv txwv li, k30 suits qis - Viscosity inks, thaum K90 yog qhov tsim ntau dua rau kev ua kom zoo.
Thixotropy Optimization: Ntsuas Faj thiab Cov Txheej Txheem Muaj Zog
Thixotropy yog hais txog cov cuab yeej ntawm cov ntaub ntawv txo qis hauv viscosity nyob rau hauv shear thiab rov ua qauv ntawm so. NVP Homopolymers txhim kho lub thixotropic cwj pwm ntawm cov xim pigment pastes los ntawm cov hauv qab no txhais tau tias:
Hydrogen Bill Network Adductation: Hydrogen Bonds tsim ntawm PvP molecular chains thiab cov xim nto nrag sai sai tom qab shear, cia lub zog rov qab lub zog ntawm so thiab tiv thaiv delamination.
Txhim Kho Colloidal ruaj khov: Adsorption txheej ntawm pvp txo cov van der kev nyiam sib xws ntawm cov xim xim, txo cov flocculation thiab ncua kev puas tsuaj ntawm lub qhov kev puas tsuaj ntawm lub qhov kev puas tsuaj thixotropic.
Rooj plaub: Tom qab ib qho kua dej hauv cov kua dej tau txais yuav Hangzhou Zaj Tshos ntawm cov xim xim los ntawm 1.8, uas tsis muaj kev ua yeeb yaj kiab tom qab 3 lub hlis ntawm cia.
Li uaNtawm dispersion stability: inhibiting flocculation thiab sedimentation
Xim Dispersion stability yog lub hauv paus ntawm rheological cov yam ntxwv. Nvp homopolymers tau ua tau ntev-}} lub sij hawm ruaj khov los ntawm ob lub tshuab sib luag:
Storyer cuam tshuam nyhav: PvP Adsorbs ntawm cov xim xim los tsim cov txheej polymer 10-20 nm tuab, thaiv cov ncaj qha particle kev sib cuag thiab tiv thaiv focculation.
Txheeb Xyuas Neutralization: Cov Pyrrolidone Rings ntawm PVP tuaj yeem neutralize ib nrab nqi ntawm cov xim xim, txo cov electrostatic ua kom muaj kev sib cais ntau dua.
Sim cov ntaub ntawv: Ntxiv 1% pvp k30 rau cov xim looj xim looj hluav taws xob qhov nruab nrab ntawm qhov loj me ntawm 2.5 μm, nrog tsawg dua 10% nce ntxiv hauv kev loj hlob ntxiv tom qab 6 lub hlis.
Hangzhou Zaj sawv ntawm NVP homopolymer daws teeb meem
Khoom nta: molecular hnyav grading thiab ua haujlwm tsim
Hangzhou Zaj sawv ntawm NVP homopoler cov kab khoom muaj cov txiaj ntsig hauv qab no:
Txheeb xyuas molecular hnyav tswj: Advanced txheej txheem xws li rraft polymerization pab tau yog qhov kev cai ntawm K tus nqi (molecular hnyav) kom tau ntsib viscosity xav tau rau cov ntawv thov sib txawv. Piv txwv li, K12 suits siab siab- kua hauv qab inkjet inkset inks, thaum K120 yog qhov zoo tagnrho rau high {4} Cov khoom siv tsho loj.
Siab purity thiab qis impurities: Kws Tshuaj Kho Mob: - qib pvp pvp (piv txwv li cov ntsiab lus hauv ion (ion cov ntsiab lus hauv qab 10 ppm, zam kev cuam tshuam nrog kev cuam tshuam nrog cov khoom lag luam kom muaj zog.
Ib puag ncig ua phooj ywg: Cov khoom lag luam ua raws li EU ncav cuag cov cai, nrog biodegradation tus nqi ntawm ntau dua 60%, haum rau eco- Tus phooj ywg nyob hauv cov xim.
Cov Khoom Siv Thov: Qhov ua tau zoo ntawm cov txheej txheem, inks, thiab tshuaj pleev ib ce
Cov dej uas muaj lub tsho tiv no: Ib qho kev tsim kho cov txheej txheem tsim hluav taws xob siv Hangzhou Zaj sawv lub PvP k90 ua cov ntaub softer, tswj cov ntaub qhwv, tswj cov ntaub softion los ntawm 500 txog 1500 lub sijhawm kom qhuav los ntawm 20%.
UV {- Txhab inks: Ntxiv 5% PVP K30 tseem ceeb txo cov kua paug viscosity (los ntawm 800 tus kab mob gloss (los ntawm 8 gu), haum} ceev luam tawm.
Cov xim kom zoo nkauj xim sib txawv: Hauv Lipstick formulations, PVP K15 xyaw nrog cov roj castor txhim kho cov hmoov txawv txav mus rau 12 hli, nrog cov ntawv thov smoother tshaj li ib txwm ua rau tsis sib xws.
Txawj txawj liCov kev sib tw thiab yav tom ntej
Txawm hais tias muaj kev ua tau zoo ntawm nvp homopolymers hauv cov xim sib tw, cov nyom hauv qab no:
High - kub ruaj khov: Hauv cov kab ntawv siab tshaj 80 degree, PVP tej zaum yauv hluav taws xob thermal, ua rau muaj kev phom sij txo. Hangzhou Zaj sawv tau nce cov thermal decomposition kub kom tshaj 250℃los ntawm kev qhia hla kev (piv txwv li, pvpp).
Sib xyaw nrog lwm cov kev sib ntxiv: PvP yuav cuam tshuam nrog cationic surfactants los ntawm kev teeb meem ntawm kev ua kom pom kev sim. Piv txwv li, hauv dej {{{- Ua cov txheej txheem, piv txwv li} {hloov cov roj silicone) tuaj yeem txhim kho dispicone roj) tuaj yeem txhim kho kev ua kom muaj txiaj ntsig los ntawm 30%.
Yav tom ntej, kev txhim kho nvp homopolers yuav tsom rauUa haujlwm hloov khothiabNtsuab Ntau Lawm:
Cov Khoom Txawj Ntse: Tsim cov xim ntse sib txuas nrog qhov kub tau los ntawm kub los ntawm kev qhia cov thermosensitive monomers (piv txwv li} ignropylacrylamide).
Biobased synthesis txoj kev: Hangzhou zaj sawv yog tshawb txog - butyrolactone txoj kev siv beepon hneev taw los ntawm 40% thaum tswj cov khoom lag luam.
Cov Lus Nquag Nug (FAQ)
Q: Puas yog nvp homopolymers haum rau cov kuab tshuaj - Raws li cov xim xim?
A: Yog. Txawm hais tias pvp yog dej - soluble, nws tseem yaj tau zoo hauv cov kuab tshuaj organic zoo li ethanol thiab acetone. Molecular lub cev hloov kho (piv txwv li, K15, K30) tuaj yeem hloov kho kom haum rau kev daws {{}}} raws cov tshuab.
Q: Yuav ua li cas xaiv covtsim nyog pvp k tus nqi?
A: Tsawg K qhov txiaj ntsig (piv txwv li, K12 {{{4 4}} k30) haum (piv txwv li cov tshuaj pleev) Hangzhou Zaj Dab Neeg muab cov khoom lag luam zoo molecular hnyav.
Q: Yuav NVP Homopolers cuam tshuam xim xim lub zog?
A: Tsis tau. Lub pob tshab thiab qhov tsis muaj lub teeb pom kev zoo ntawm PVP ua nws cov kev cuam tshuam ntawm cov xim tsis txaus ntseeg, thiab nws cov kev tawg feem ntau yog txhim kho xim sib xws.
Q: Cov khoom lag luam puas sib ntsib cov qauv kev sib chwv?
A: Hangzhou Zaj sawv lub PvP K30 (USP qib) yog FDA- Tau lees paub thiab tuaj yeem siv rau hauv cov khoom noj ntim khoom noj.
Q: Yuav ua li cas khaws cia nvpHomopolers kom tsis txhob poob ntsej muag?
A: Khaws rau hauv qhov chaw txias, qhuav (tsawg dua los yog sib npaug rau 30 degree), deb ntawm tshav ntuj. Kaw tom qab qhib kom tiv thaiv kom tsis txhob ua kom haum noo.
