Polyvinyl pyrrolidone, cov ntsiab lus xyaw hauv qab no 1%?
Raws li cov khoom siv muaj peev xwm, koj yuav tsum tsis txhob nkag siab cov khoom xyaw, tab sis kuj twv cov kev pom zoo
Polyvinyl pyrrolidone (PVP) feem ntau yog dawb lossis ze li ntawm cov hmoov dawb
Nws yog tsuas yog siv los ua cov tuab dua lossis yeeb yaj kiab - Txoj kev sib sau tus neeg sawv cev hauv cov tshuaj pleev ib ce hauv tshuaj pleev ib ce
Cov lus qhia tshwj xeeb yog qhov txawv los ntawm K tus nqi. Qhov siab dua tus nqi k, siab dua cov molecular hnyav thiab viscosity. Feem ntau siv yog K-15, K-15, K-60, thiab K90
Vim li no, cov ntsiab lus ntawm polyvinyl pyrrolidone hauv cov tshuaj pleev ib ce yuav tsum tau txheeb xyuas raws li cov khoom lag luam tshwj xeeb, thiab tsis tuaj yeem siv raws li 1% sib faib cov kab
Piv txwv li, cov qhab nia ntxiv rau hauv cov ntsiab lus tsawg dua 1%, thaum lub dav dav ntxiv rau hauv cov plaub hau gel ntau dua 1%
Hais Txog Cov Khoom:
【Tsom ntsoov rau cov kev cai ua hluavtaws ntawm cov organic me me molecules thiab polymers】
Polyvinylprolidone - vinyl acetate copolymer npaj txhij los ntawm cov vinylrolidone (v pp) thiab va) raws li monomers. Nws yog dav siv nyob rau hauv cov tshuaj pleev ib ce, tshuaj, cov nplaum, nplaum thiab lwm liaj teb vim nws cov yeeb yaj kiab zoo heev} Txoj kev ua yeeb yam, thiab biocompatibility. Ua raws li qhov sib piv ntawm VP rau VA, nws Hydrophilicity, Hydrothness thiab solubility tuaj yeem hloov kho kom tau raws li cov cai thov sib txawv.
【Lub cev muaj zog】
Lub cev lub cev lub cev
(1) tsos: feem ntau yog dawb lossis me ntsis hmoov daj, nws kuj tuaj yeem npaj rau hauv daim ntawv ntawm cov kua aqueous.

Molecular hnyav thiab muaj pes tsawg leeg
(1) Qhov hnyav hnyav: nyob ntawm daim ntawv thov, qhov hnyav molecular tuaj yeem hloov kho hauv thaj tsam ntawm 10,000 rau 1,000,000.
(2) cov piv txwv tivthaiv: Qhov sib piv ntawm VP rau VP rau V P rau VA feem ntau ntawm 30:70 thiab 70 thiab kev ua tau zoo tuaj yeem hloov kho los ntawm kev sib piv.
Cov Khoom Tshwj Xeeb
(1) Zaj duab xis {{1} Taug kev cov cuab yeej: nws tuaj yeem tsim lub pob tshab thiab du ua zaj duab xis nyob rau saum npoo ntawm ntau substrates.
(2) hloov pauv tau thiab cov nplaum: nws muaj cov nplaum zoo rau saum npoo ntawm daim tawv nqaij thiab lwm yam ntaub ntawv thiab hloov kho tau zoo.
(3) Dej vapor permeability: tus tsim zaj duab xis tau muaj huab cua tsim nyog, uas yuav pab tswj kom muaj kev nqus tau ntawm daim tawv nqaij lossis sab nraud.
【Daim Ntawv Thov Thaj Av】
Tshuaj pleev ib ce thiab cov khoom siv saib xyuas tus kheej
(1) Cov khoom lag luam styling: ua yeeb yaj kiab - Txoj kev sib sau tus neeg sawv cev, mousse, thiab gel, nws muab ib tug ntev- kav ntev rau cov plaub hau.
(2) Cov khoom tu tawv nqaij: nws yog siv los ua cov moisturizer thiab cas voos thiab qhov ncauj qhov ntswg los pab ua zaj duab plaub tiv thaiv.
(3) Cov Khoom Kho Hniav: Siv hauv daim di ncauj thiab qhov muag duab ntxoov ntxoo txhawm rau txhim kho kev ductility thiab adhesion ntawm cov khoom.
Kho tsev kho mob
(1) Cov neeg nqa tshuaj: vim nws biocompatibility, nws tuaj yeem siv los ua tus tswj hwm kev tswj hwm thiab cov khoom siv tau los txhim kho cov tshuaj.
(2) Zaj duab xis {{1} Txoj kev sib sau khoom: Ua zaj duab xis tiv thaiv hauv cov ntaub qhwv hauv kev kho kom zoo.
(3) Cov nplaum: Siv nyob rau hauv cov ntsiav tshuaj tsim los txhim kho cov tshuab ua kom muaj zog thiab solubility ntawm cov ntsiav tshuaj.
Kev Siv Siv
