Zipangizo zapulasitiki: Ndi chiyani chabwino, EVA kapena PVC?

EVA ZINAWATHERA ndi PVC Zonsezi ndi mtundu wa pulasitiki, zinthu zomwe timapanga m'miyoyo yathu ndizofala kwambiri, ndipo nthawi zambiri, zinthu ziwirizi zimatha kusinthana, kotero anthu ambiri sadziwa kusiyana pakati pawo, kotero lero kuti tiyambe mwachidule EVA, PVC ndiye chinthu chabwino, EVA ndi PVC.

Katundu wa EVA

Dzina la mankhwala a EVA ndi ethylene – vinyl acetate copolymer, ndi polima, mawonekedwe ake a molekyulu ndi (C2H4)x. (C4H6O2)y, amatha kuyaka, akayaka amapanga carbon monoxide ndi carbon dioxide. Amatha kukalamba bwino, amakana madzi, amakana ozoni komanso amakhazikika pa mankhwala. EVA ili ndi makhalidwe awa.

1、Anti-vibration: Ili ndi rebound komanso yolimba kwambiri kupsinjika, kulimba bwino, kotero ndi chinthu chabwino kwambiri choletsa kugwedezeka komanso choteteza.

2, choteteza mawu chosalowa madzi: ndi kapangidwe ka thovu lotsekedwa, silingatenge madzi, silinganyowe chinyezi, ndipo choteteza mawu ndi chabwino kwambiri.

3, kutchinjiriza kutentha: kapangidwe ka thovu kotero kuti EVA ilinso ndi kutchinjiriza kutentha kwabwino kwambiri komanso kutchinjiriza kutentha.

4, zosavuta kukonza: EVA palibe malo olumikizirana, kukanikiza kotentha, kudula, ndi kukonza laminating ndikosavuta.

5, kukana dzimbiri: EVA yokha ndi yotsutsana ndi mabakiteriya, yopanda poizoni komanso yopanda kukoma, palibe kuipitsidwa kwa chilengedwe, pali kukana bwino kwa asidi ndi alkali.

Kugwiritsa Ntchito: Zipangizo za EVA zitha kupangidwa kukhala nsapato, filimu, waya ndi chingwe, zoseweretsa, zomatira zotentha zosungunuka, emulsion ya EVA ndi zinthu zina.

Zithunzi za PVC

Dzina la mankhwala aPVCNdi polyvinyl chloride, ndi ufa woyera wokhala ndi kapangidwe kake kosakhala ndi mawonekedwe ndipo sungakhazikike bwino ku kuwala ndi kutentha. Ngati nthawi zambiri imawola padzuwa, kapena ngati ili pa 100°C, imawola ndikupanga hydrogen chloride, zomwe zimapangitsanso kuti mtundu wake usinthe ndipo mphamvu zake zamakaniko zichepa chifukwa cha izi. Kutentha komwe kumagwiritsidwa ntchito nthawi zambiri kumakhala pakati pa -15 digiri ndi 55 digiri. Pogwiritsa ntchito zipangizo za PVC, zinthu zina zokhazikika ziyenera kuwonjezeredwa.

Kugwiritsa Ntchito: PVC imagwiritsidwa ntchito m'njira zosiyanasiyana, monga mu zipangizo zomangira, zinthu zamafakitale, zofunikira za tsiku ndi tsiku, matailosi apansi, chikopa chochita kupanga, chikopa cha pansi, mawaya ndi zingwe, mafilimu opaka, mabotolo apulasitiki, zinthu zotulutsa thovu, ulusi, ndi zina zotero.

Zithunzi za PVC

1、Ili ndi mpweya wabwino komanso kulimba, ndipo mphamvu zake zimakhala zapamwamba kwambiri.

2、Wopepuka: PVC imapanga zinthu monga mapaipi, omwe ndi opepuka komanso osavuta kunyamula ndi kutsitsa.

3, mphamvu zabwino zotetezera kutentha, PVC nthawi zambiri imagwiritsidwa ntchito popanga waya ndi chivundikiro cha pulasitiki cha chingwe.

4, sichikhudza ubwino wa madzi: kutsimikizira mayeso, chitoliro cha PVC ndi zolumikizira, sizikhudza ubwino wa madzi, ndiye chitoliro chabwino kwambiri chogwiritsira ntchito mapaipi amadzi.

5, utoto wabwino, sikuti umangowonetsa mtundu wachilengedwe wokha, komanso umatha kupanga utoto wokongola komanso wodabwitsa, komanso mawonekedwe abwino azinthu.

Mwachitsanzo, EVA ndi PVC zitha kupangidwa ngati nsapato zophimba pansi kuti zione kusiyana pakati pa nsapato zomwe zimapanga.

1, nsapato za EVA ndi zopepuka, zofewa komanso zomasuka, zopanda poizoni komanso zachilengedwe, sizimawonongeka, sizimanyowa komanso sizimanunkha, komanso zimayamwa kutentha komanso zimateteza kutentha, zomwe nthawi zambiri zimagwiritsidwa ntchito popanga nsapato zapakati. Koma EVA yokha ndi yoterera kwambiri, chifukwa chake kupanga nsapato kumafunika kuti zisamaterereke.

2, PVC sole anti-slip effect ndi yabwino, nsapato zabwino nazonso ndi zofewa kwambiri, sizivuta kupeza fumbi, komanso zosavuta kuyeretsa. Ndi zotsika mtengo, zimatha kufewa ndipo zimakhala ndi utoto wabwino, ndipo zimatha kupangidwa mumitundu yosiyanasiyana.

Kuphatikiza apo, PHYLON ndi chinthu chodziwika bwino m'zidendene za nsapato, ndi chidendene chachiwiri cha thovu, pamwamba pake ndi poyera komanso pali makwinya, chinthu chake chachikulu ndi chopepuka, chotanuka bwino, komanso magwiridwe antchito abwino otetezera, kotero nthawi zambiri imagwiritsidwa ntchito popanga nsapato zamasewera. PHYLON ili ndi zabwino zambiri, komanso ili ndi vuto loti sikophweka kuiwononga.
