Chofunika

Maphunziro a Mankhwala:Uvcb, plastics & mphira -> ma polima
Kumwetulira kwa Canonan:CC (= O) OC = CC = C
Kufotokozera:Ethylene-vinyl acetate copolymer has good impact resistance and stress crack resistance, softness, high elasticity, puncture resistance and chemical stability, good electrical properties, good biocompatibility, and low density, and is compatible with fillers, flame retardants agents have good compatibility.It is mainly?used for plastic products.
Matenda a thupi a vinyl acetate amapezeka ngati sera yoyera mu pellet kapena mawonekedwe a ufa. Makanema amapezeka.
Gwiritsani Ntchito:Kusuta Kusinthika, utoto umazungulira, ma gasketi ndi ziwalo zoumbidwa kwa autos, magalasi apulasitiki ndi mapampi.

Mawu owonjezera

Ethylene-vinyl acetate corolymer, nthawi zambiri zimafupikitsidwa ngati Eva, ndizomwe zimapangidwa kuchokera ku kuphatikiza kwa ethylene ndi vinyl acetate monomers. Ndizinthu zofananira zomwe zimagwiritsidwa ntchito pazogwiritsa ntchito zosiyanasiyana chifukwa cha zinthu zomwe zimachitika.
Eva Curkolimer ali ndi malo ochepa osungunuka, kusinthasintha kosinthika, komanso kukhazikika kwamphamvu komanso kutukuka. Imagwirizana ndi madzi, ma radiation ya UV, ndi mankhwala, omwe amapangitsa kuti ikhale yoyenera kwa mapulogalamu akunja. Ilinso ndi kutsatira bwino magawo ambiri, ndikupanga kukhala yabwino kugwiritsa ntchito ngati binder kapena zomatira.
Chimodzi mwazinthu zazikulu za Eva ali popanga zikopa. Amagwiritsidwa ntchito kwambiri kuti amapanga zida zokutira ndi zodutsa, monga nsapato za nsapato, zida zothamanga, ndi zida zapamalo. Maluwa a Eva amapereka modabwitsa, kugwedeza nkhawa, ndi kutonthozedwa.
Eva Curolmer amagwiritsidwanso ntchito popanga mafilimu ndi ma sheet. Kumveka kwake, kusinthasintha, komanso kutentha kochepa kumapangitsa kukhala koyenera kugwiritsa ntchito ngati malo obiriwira, galasi lamphamvu, ndi mapazi a dzuwa.
Magetsi ndi mafuta osokoneza bongo a Eva amapangitsa kuti ikhale yothandiza mu waya ndi zingwe. Mafuta a Eva ndi zida zotuwa zimagwiritsidwa ntchito kuteteza ndi zingwe zamagetsi ndi zingwe. Ntchito zamagetsi za Eva zimaphatikizapo zigawo zamagalimoto, zida zamankhwala, ndi zida za madola.
Ponseponse, ethylene-vinyl acetate corolymer ndi zinthu zofananira ndi zinthu zabwino zomwe zimapangitsa kuti zikhale zoyenera kwa mapulogalamu osiyanasiyana.

Karata yanchito

Ethylene-vinyl acetate corolymer (Eva) ali ndi ntchito zingapo pamakampani osiyanasiyana chifukwa cha kuphatikiza kwake kwa katundu. Nazi ntchito zodziwika bwino za Eva:
Nsapato:Eva amagwiritsidwa ntchito kwambiri popanga nsapato, makamaka kwa mkati ndi ma smonales. Imapereka kupsinjika, kugwedeza nkhawa, komanso kusinthasintha, kupangitsa kuti ikhale chisankho chotchuka pa nsapato zothamanga, nsapato, ndi oterera.
Kuyika:Eva amagwiritsidwa ntchito popanga mapulogalamu monga momwe amathandizira kuti athe kukana komanso kusinthasintha. Nthawi zambiri amagwiritsidwa ntchito ngati mapangidwe oteteza, mabokosi achiphona, ndi zingwe zamabokosi ndi zotengera kuti zitetezeke ndi zinthu zosakhazikika kapena zofooka.
Asite ndi Zisindikizo:Eva Curolmer amagwiritsidwa ntchito ngati maziko a maziko opanga zomata ndi zimbudzi. Limapereka chotsatsa bwino kwa magawo osiyanasiyana, monga pulasitiki, zitsulo, ndi nkhuni, kupanga kukhala koyenera kugwirira ntchito mogwirizana.
Waya ndi chingwe chinsinsi:Eva amagwiritsidwa ntchito ngati chotchinga cha mawaya amagetsi ndi zingwe chifukwa cha magetsi abwino. Zimapereka chinyezi, mankhwala, komanso kukalamba, kuonetsetsa chitetezo komanso kudalirika kwa makina amagetsi.
Filimu ndi pepala:Eva nthawi zambiri amagwiritsidwa ntchito kupanga mafilimu ndi ma sheet omwe ali ndi makulidwe osiyanasiyana. Makanema awa amapeza mapulogalamu omwe alimi paulimi, zokutira zobiriwira, zomwe zimachitika chakudya, ma solar panels, ndi galasi lonyowa.
Zipangizo Zachipatala:Eva amagwiritsidwa ntchito pazantchito yachipatala kupanga zida zamankhwala, monga catheter, ma cung, ndi maluso opaleshoni. Zimaperekanso zinthu zachilengedwe, kusinthasintha, komanso kutsata kosavuta kwa ntchito zamankhwala.
Zoseweretsa ndi zosangalatsa:Eva amagwiritsidwa ntchito kwambiri popanga zoseweretsa komanso zinthu zosangalatsa, kuphatikizapo zithunzi za thovu, zida zodzipinda, zogama, ndi zida zamasewera. Imapereka kupsinjika, chitetezo, ndi kulimba kwa ntchitozi.
Magawo Opanda:Zida za Eva zojambulajambula zimagwiritsidwa ntchito mu ntchito yamagalimoto pamavuto omveka, kugwedezeka, komanso kukana. Zimathandizira kuchepetsa phokoso, kukulitsa chitonthozo, ndikuteteza mu galimoto.
Izi ndi zitsanzo zochepa chabe za ntchito zambiri za Eva. Kusintha kwake, kusinthasintha, ndi kulimba kumapangitsa kuti zinthu zambiri zamasulire.
