Polyvinylpyrrolidone K90 (PVP K90), tseem hu ua Povidone K90, yog ib qho tseem ceeb ntawm cov khoom siv polymer uas ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ua haujlwm thiab kev ruaj ntseg ntawm cov nplaum nplaum. Nrog nws qhov hnyav molecular thiab cov khoom zoo sib xws, PVP K90 ua haujlwm ntau yam ntxiv uas ua rau muaj txiaj ntsig zoo thiab siv tau ntawm cov nplaum nplaum.
Cov yam ntxwv tseem ceeb ntawm PVP K90
PVP K90 yog xim dawb rau tawm -dawb, tsis muaj ntxhiab lossis ze li tsis muaj ntxhiab hygroscopic zoo flake lossis hmoov. Nws nthuav tawm zoo solubility, biocompatibility, physiological inertness, thiab zaj duab xis - tsim muaj peev xwm. Cov khoom no ua rau PVP K90 tsim cov qauv colloidal ruaj khov hauv cov nplaum nplaum thaum tswj cov khoom ruaj khov thiab kav ntev.Tsim los ntawm ULKM raws li ISO nruj - ntawv pov thawj kev tswj hwm zoo, peb PVP K90 ua kom muaj kev ua tau zoo thiab txhim khu kev qha hauv ntau daim ntawv thov nplaum.
Kev ua haujlwm ntawm PVP K90 hauv Cov Khoom Siv Kua nplaum
1. Adhesive Properties
PVP K90 qhia cov yam ntxwv tshwj xeeb nplaum rau iav, hlau, thiab yas, ua kom muaj kev sib raug zoo ntawm ntau yam ntaub ntawv hauv cov kua nplaum nplaum. Nyob rau tib lub sijhawm, nws ua raws li cov khoom tawg thiab khi rau slurries, pigments, thiab lwm yam khoom, txhim kho cov nplaum nplaum thiab muaj peev xwm txuas tau ntawm cov nplaum nplaum.
2. Muaj peev xwm Thickening
PVP K90 muaj cov khoom tuab zoo heev uas ua rau cov viscosity ntawm cov nplaum nplaum, ua rau lawv ruaj khov dua thiab tiv thaiv kev ntws los yog poob thaum siv.
3. Zaj duab xis-Kev ua haujlwm
PVP K90 tuaj yeem tsim cov yeeb yaj kiab tiv thaiv ntawm cov nplaum nplaum, tiv thaiv kom tsis txhob ya raws ntawm cov nplaum nplaum thiab yog li txuas ntxiv cov khoom txee lub neej.
4. Dispersion thiab Affinity
PVP K90 ua kom muaj kev sib cais ntawm tag nrho cov khoom nyob rau hauv cov kua nplaum, tiv thaiv particle agglomeration. Tsis tas li ntawd, nws khi zoo nrog lwm cov khoom siv hauv cov nplaum nplaum, txhim kho kev ua haujlwm tag nrho ntawm cov khoom kawg.
Qhov zoo ntawm kev siv PVP K90 hauv cov nplaum nplaum
1. Txhim kho cov khoom zoo
Qhov sib ntxiv ntawm PVP K90 ho txhim kho cov nplaum lub zog, adhesion zog, thiab ruaj khov ntawm cov nplaum nplaum, ua rau cov khoom ruaj khov thiab txhim khu kev qha.
2. Txhim kho cov neeg siv kev paub
PVP K90's thickening thiab zaj duab xis- tsim cov yam ntxwv txhim kho cov neeg siv kev paub los ntawm kev ua kom du thiab txawm tias daim ntawv thov, tiv thaiv dej los yog tsis xav tau thaum siv.
3. Kev siv dav dua
PVP K90's wide compatibility tso cai rau nws siv rau kev sib txuas ntau yam ntaub ntawv xws li ntawv, yas, thiab hlau, yog li nthuav daim ntawv thov teb rau cov khoom nplaum.
Raws li tus kws tshaj lij hauv PVP kev tsim khoom, ULKM muab PVP K90 nrog cov ntaub ntawv ua tiav kev tswj hwm thiab kev txhawb nqa thoob ntiaj teb,pab peb cov neeg muas zaub ua tau raws li cov qauv zoo thoob ntiaj teb thiab kev ua lag luam.
Kev txiav txim siab tseem ceeb rau kev siv PVP K90:
Thaum siv PVP K90 raws li cov kua nplaum ntxiv, nws qhov muaj zog hygroscopic yuav tsum tau saib xyuas. Cov khoom yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav kom tsis txhob ya raws thiab degradation. Tsis tas li ntawd, qhov ntau npaum li cas thiab qhov sib piv ntawm PVP K90 yuav tsum tau kho kom raug raws li cov kev thov tshwj xeeb thiab cov txheej txheem yuav tsum ua kom tau txais txiaj ntsig zoo.
Xaiv ULKM raws li koj qhov kev ntseeg siab PVP K90 tus neeg muab khoom
Nrog rau peb qhov chaw tsim khoom muaj peev xwm tsim tau 3,000 tons ntawm PVP ib xyoos ib zaug, ULKM ua kom zoo ib yam thiab ruaj khov rau koj cov khoom siv kua nplaum uas xav tau. Peb cov kev tswj hwm zoo, txhawb nqa los ntawm ISO 9001 daim ntawv pov thawj thiab REACH ua raws, lav tias peb PVP K90 ua tau raws li cov qauv kev lag luam siab tshaj plaws.
Txawm hais tias koj tab tom tsim cov kua nplaum tshiab los yog ua kom zoo dua cov khoom uas twb muaj lawm,ULKM's PVP K90muab cov kev ua tau zoo thiab kev lees paub zoo uas koj xav tau. Tiv tauj peb hnub no kom thov cov qauv thiab cov ntaub ntawv qhia txog kev ua haujlwm rau koj qhov kev thov tshwj xeeb.
