Ntchito Zosiyanasiyana za Poly(1-vinylpyrrolidone-co-vinyl acetate) Copolymer: Njira Yopangira Mafilimu Olonjeza

Poly(1-vinylpyrrolidone-co-vinyl acetate)copolymer, yomwe imadziwikanso kuti PPVVA, ndi polima yosunthika yomwe imapereka ntchito zosiyanasiyana chifukwa cha luso lake lopanga mafilimu.PVPVA imakhala ndi kusungunuka kwabwino kwambiri m'madzi ndi zosungunulira za organic ndipo imatha kuphatikizidwa mosavuta mumitundu yosiyanasiyana.Kuphatikiza pa kukhazikika kwa kutentha komanso kusagwirizana ndi kuwonongeka, copolymer imawonetsanso kuwongolera kwamagetsi, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pamagetsi ndi makina opangira zokutira.Mu blog iyi, tiwona mikhalidwe yapadera komanso momwe tingagwiritsire ntchito PPVVA.

1. Kuchita bwino kwambiri popanga mafilimu:

Choyamba, ma copolymers a PVVA amawonekera kwambiri chifukwa cha luso lawo lopanga mafilimu.Akagwiritsidwa ntchito ngati chophatikizira pakupanga monga zokutira, zomatira ndi zinthu zosamalira anthu, zimapereka mafilimu osalala, ofananirako omwe amawonjezera mawonekedwe ndi kulimba kwa mankhwalawa.Mphamvu zopanga filimu za PVPVA zimatsimikizira kuphimba koyenera ndi kumamatira, kupititsa patsogolo ntchito zosiyanasiyana.

2. Kusungunuka m'madzi ndi zosungunulira organic:

PVPVA copolymers amawonetsa kusungunuka kwabwino m'madzi ndi zosungunulira zosiyanasiyana.Katunduyu amalola kuti azitha kuphatikizidwa mosavuta m'mapangidwe osiyanasiyana ndi machitidwe, ndikupangitsa kuti ikhale yogwiritsidwa ntchito mosiyanasiyana m'mafakitale osiyanasiyana.Kuchokera pamankhwala kupita ku zopopera tsitsi, PVVA imagwirizana komanso yokhazikika muzosungunulira zosiyanasiyana, zomwe zimapatsa opanga ma formula kusinthasintha pakukula kwazinthu.

3. Kusintha kwa conductivity kwa zokutira zamagetsi ndi conductive:

Kuthekera kwapadera kosintha ma conductivity a PPVVA kumapangitsa kuti ikhale yabwino pazogwiritsa ntchito zamagetsi zamagetsi komanso zamagetsi.Ndi kusintha kwachizolowezi, copolymer imatha kukwaniritsa zofunikira zamagetsi, ndikupangitsa kuti ikhale chinthu choyenera kugwiritsa ntchito monga masensa, ma board ozungulira osindikizidwa ndi zokutira antistatic.Kutha kwa PVPVA popereka ma conductivity popanda kukhudza mapangidwe opanga mafilimu kumapangitsa kukhala chisankho chabwino kwambiri pamapulogalamu apaderawa.

4. Kukhazikika kwamafuta ndi kukana kutentha:

Chinthu chinanso chodziwika bwino cha PVPVA copolymer ndikukhazikika kwake kwamafuta komanso kukana kuwonongeka.Izi zimapangitsa kuti ikhale yabwino kwa mapulogalamu omwe amafunikira kutentha kwambiri kapena malo ovuta.Kaya ndi zomatira zomangirira magalimoto kapena zokutira zodzitchinjiriza pazida zamafakitale, PVVA imawonetsetsa kuti moyo wautali komanso wokhazikika muzovuta kwambiri.

Poly(1-vinylpyrrolidone-co-vinyl acetate)copolymer ndi zinthu zambirimbiri zokhala ndi zida zabwino kwambiri zopangira mafilimu, kusungunuka m'madzi ndi zosungunulira za organic, ma conductivity amagetsi osinthika, komanso kukhazikika kwamafuta.Makhalidwewa amachititsa kuti ikhale yofunika kwambiri m'mafakitale osiyanasiyana, kuphatikizapo zomatira, zokutira, mankhwala ndi zamagetsi.PVPVA imathandizira opanga kupanga zinthu zatsopano zokhala ndi magwiridwe antchito komanso olimba.Pamene kafukufuku wa sayansi ya polima akupita patsogolo, tikuyembekeza kuwona mapulogalamu osangalatsa a PPVVA mtsogolomo.
