Kugwiritsa ntchito thovu la EVA

EVA ndiye polima wachinayi pakukula kwa ethylene pambuyo pa HDPE, LDPE ndi LLDPE.Poyerekeza ndi zipangizo zachikhalidwe, mtengo wake ndi wotsika kwambiri.Anthu ambiri amaganiza kuti thovu la EVA ndilophatikizira bwino chipolopolo cholimba ndi chipolopolo chofewa, kusunga ubwino wa thovu lofewa komanso lolimba ndikusiya kuipa.Komanso, kusinthasintha kwachilengedwe pamapangidwe azinthu ndi kuthekera kopanga ndichinthu chofunikira kwambiri m'makampani ena otsogola padziko lonse lapansi kutembenukira ku thovu la EVA pakafunika zida zapamwamba komanso zotsika mtengo.

Chithunzi chochokera: foamty

Kupitilira kusinthika, zinthu za thovu za EVA zimasamalira moyo wathu watsiku ndi tsiku ndi zochitika zabizinesi, ndipo zadzetsa chidwi kwa ogwiritsa ntchito.Nsapato, mankhwala, mapanelo a photovoltaic, masewera ndi zosangalatsa, zoseweretsa, matimu apansi/yoga, zonyamula, zida zamankhwala, zida zodzitetezera, zopangira masewera am'madzi zikufunika kwambiri pakupanga zinthu zapulasitiki zolimba, ndipo gawo la msika wa thovu la EVA likupitilizabe. kukula kwatsopano kwa.

EVA thupi ndi makina katundu

Makhalidwe a EVA copolymers amatsimikiziridwa makamaka ndi vinyl acetate zomwe zili ndi kuchuluka kwa fluidity.Kuwonjezeka kwa zinthu za VA kumawonjezera kachulukidwe, kuwonekera komanso kusinthasintha kwa zinthuzo ndikuchepetsa kusungunuka ndi kuuma.Ethylene-vinyl acetate copolymer (EVA) ndi zinthu zotanuka kwambiri zomwe zimatha kusungunulidwa kuti zipange thovu lofanana ndi labala, koma mwamphamvu kwambiri.Imasinthasintha kuwirikiza katatu kuposa low density polyethylene (LDPE), imakhala ndi kutalika kwa 750%, ndipo imakhala ndi kutentha kokwanira 96 ​​° C.

Kutengera zosakaniza zomwe zikupanga, magawo osiyanasiyana a kuuma kwa EVA atha kukwaniritsidwa.Ndikofunikira kukhalabe ndi kuuma kwapakati chifukwa EVA sabwereranso mawonekedwe ake pambuyo pa kukanikiza kosalekeza.Poyerekeza ndi EVA yolimba, EVA yofewa imakhala yosagonjetsedwa ndi abrasion ndipo imakhala ndi moyo wautali payekha, koma imakhala yabwino.

Foam ya anti-static EVA sikuti imakhala ndi anti-static buffering effect, komanso imakhala ndi kukana kwamphamvu kwamphamvu.
Kutengera thovu la ESD EVA, pali mitundu yambiri: mabokosi ojambulidwa a thovu, zoyika thovu, zingwe zamabokosi a PP, zoyika zowongolera, ndi zina zambiri,

Kwa mafoni am'manja, ma terminals a 3G, makompyuta, zida za optoelectronic, mabokosi obweza.Ikani zigawo za kompyuta yolembera mu kagawo kakhadi kopangidwa ndi thonje la thonje, ndipo sonkhanitsani mzerewu pamodzi kuti ntchitoyo ikhale yabwino.Amagwiritsidwa ntchito mu mavabodi ndi PCB zokambirana kupewa kudula zida zamagetsi ndi manja pa ntchito;Chiwonetsero chachitetezo cha LCD ndi mabwalo owongolera amizere yopangira ma LCD.
