PVA
Inzoga nyinshi PVA Polyvinyl
Incamake y'ibicuruzwa
Inzoga ya polyvinyl (PVA) ni polymer-eregiteri ya polymer isanzwe yera muri flake, flocculent, cyangwa ifu.
Icya kabiri, ibiranga ibicuruzwa
Amazi meza cyane: arashobora gushonga mumazi mubushyuhe butandukanye kugirango bibe igisubizo kiboneye.
Gufata neza: bifite ingaruka zikomeye zo guhuza ibikoresho bitandukanye.
Gukora firime nziza: Filime yashizweho ifite imbaraga nyinshi kandi zihinduka.
Kurwanya ibishishwa: Ku rugero runaka, birashobora kurwanya isuri yumuti usanzwe.
Biocompatibilité: Ugereranije ntabwo ari uburozi kandi bwinshuti kumubiri wumuntu nibidukikije.
gukoresha ibicuruzwa
Inganda
Ikoreshwa nkibikoresho byintambara kugirango utezimbere imbaraga no kwambara birwanya ubudodo.
Gucapa no gusiga abafasha, fasha gusiga irangi no kugabana kimwe.
Inganda
Impapuro zingana zingana kugirango wongere imbaraga namazi yo guhangana nimpapuro.
Pigment coating yifata kugirango itezimbere imiterere yimpapuro.
Umwanya ufatika
Gufata ibiti, impapuro, fibre nibindi bikoresho.
Inganda zubaka
Inyongera ya sima kugirango itezimbere imitungo ya sima.
Urwego rwubuvuzi
Ibikoresho fatizo bya capsule yibiyobyabwenge, ibikoresho byubuvuzi bwamaso.
Inzira yumusaruro
Mubisanzwe byateguwe na alcoolise ya polyvinyl acetate.
Amahirwe y'isoko
Hamwe no kwiyongera kubikoresho bikora neza mubikorwa bitandukanye, ibyifuzo byisoko rya PVA ni binini. Bitewe no kuzamura inganda gakondo nk'imyenda no gukora impapuro, ndetse no guteza imbere imirima igaragara nka biomedicine n'ibikoresho bya elegitoroniki, biteganijwe ko isoko ryayo rizakomeza kwiyongera.
koresha ingamba
Irinde ubushuhe n'ubushyuhe bwinshi mugihe ubitse.
Iyo ushonga, ubushyuhe n'umuvuduko ukabije bigomba kugenzurwa kugirango habeho guseswa bihagije kandi imikorere ntigire ingaruka.
Hitamo icyitegererezo gikwiye hamwe nibisobanuro ukurikije ibisabwa bitandukanye.
Kurugero, mu nganda z’imyenda, PVA ifite impamyabumenyi yihariye na alcoolise ikeneye gutoranywa ukurikije ibikoresho nibikorwa bisabwa byintambara; Mugukoresha ibifatika, gushiraho no gukoresha PVA bigomba guhinduka ukurikije imiterere yifatizo.
Muri make, inzoga za Polyvinyl zigira uruhare runini mubice byinshi hamwe nimiterere yihariye, zitanga inkunga ikomeye mugutezimbere inganda zijyanye.
