IMITERERE:
Ibisobanuro:
Ni homopolymer ihuza ibyuma bya vinylpyrrolidone. Ni ifu y'umweru cyangwa iy'umweru idakora neza. Ifite impumuro mbi nke. Ntishobora gushonga mu bintu bisanzwe nk'amazi, ethanol na ether. Bityo uburemere bwayo ntibushobora gupimwa. Ariko, PVP ifite ubushobozi bwo gukora ibintu bitandukanye (nk'ibintu bya "Hu" bishobora gutuma ubwoko butandukanye bwa divayi n'ibinyobwa bihinduka ibara). Nanone kandi, ikurwamo byoroshye nyuma yo kuyiyungurura kubera ko idashonga neza.

Imikoreshereze
1. Inganda zikora ubwiza bw'uruhu: PVPK series ishobora gukoreshwa nk'umuti wo gusukamo amavuta, ikora filime, igabanya ubushyuhe, amavuta yo kwisiga n'ubukorikori mu nganda zikora ubwiza bw'uruhu, kandi ishobora gukoreshwa mu bikoresho byo kwita ku musatsi nka spray y'umusatsi, mousse, gel yo gusiga umusatsi, shampoo, fixative y'umusatsi n'irangi ry'umusatsi; Ibikoresho byo kwita ku ruhu nka lipstick, sunscreen, moisturizer n'ibindi bikoresho byo kwisiga nka modifiers, deodorants, toothpaste, nibindi.
2. Inganda zikora imiti: PVPK30 (urwego rw'imiti) ni imwe mu miti mishya ikoreshwa mu gukora imiti, ishobora gukoreshwa nk'ikintu gifunga ibinini n'udukoko, ikintu gishonga n'ikintu gikomeza gutera inshinge, ikintu gifasha mu gutera imiti mu turemangingo, ikintu gikwirakwiza amazi n'ibintu bisiga irangi, ikintu gikomeza imiti mu misemburo n'imiti ikoresha thermosensitive, ikintu gifasha mu gukora imiti idashonga, ikintu gikuraho uburozi n'amavuta yo mu maso, n'ikintu gisiga irangi. Hari imiti amagana ikoresha PVP nk'ikintu gikomeza imiti. PVPK30 y'urwego rw'imiti yemejwe n'Ikigo cy'Igihugu cy'Ubuvuzi cya Repubulika y'Abaturage y'Ubushinwa.
3. Izindi nganda zikoresha: Ikoreshwa nk'ibinyabutabire, ibikoresho bitanga filime, ibinyabutabire bigabanya ubushyuhe, n'ibindi bikoresho byongera mu nganda nka amarangi n'ibirahure, pulasitiki, resins, insinga z'ibirahure, wino, kole, isabune, filime z'amafoto, ibinini, imiyoboro ya televiziyo, imiti ikoreshwa mu gukora, kaseti zifata, imiti yica udukoko, impapuro, gucapa no gusiga amarangi mu myenda.
Gupakira no Kohereza
25kg/ikarito cyangwa indobo ya pulasitiki, ifunze neza kandi ibikwe ku bushyuhe bw'icyumba, yumye, kandi kure y'urumuri.
Ni iy'ibicuruzwa rusange kandi ishobora gutangwa binyuze mu nyanja no mu kirere
Bika kandi ubibike
Igihe cyo kubika: Amezi 24 uhereye igihe byakorewe mu ipaki y’umwimerere idafunguye, bibitswe ahantu hakonje kandi humutse, kure y’izuba ryinshi, amazi.
Ububiko bufite umwuka uhagije, Butuma ibintu bishya bishyuha, butandukanyijwe n'ibikomoka kuri okiside, aside.
