Ethylene-vinyl acetate copolymer CAS 24937-78-8 (EVA) ine huwandu hwakawanda hwekushandisa, dzinotevera ndidzo nzvimbo dzayo dzekushandisa:
Munda wefirimu wakaonda
Firimu rekurima: EVA ine yakanaka kutapurirana mwenje, kuchengetedza kupisa uye kuramba mamiriro ekunze, uye inowanzoshandiswa mukugadzira firimu rekurima. Inogona kunyatso kuchengetedza tembiricha uye hunyoro mugreenhouse, kukurudzira kukura kwezvirimwa, uye kuwedzera hupenyu hwebasa remufirimu.
Packaging firimu: EVA firimu ine yakanaka kuchinjika, pachena uye puncture kuramba, yakakodzera kurongedza zvigadzirwa zvakasiyana-siyana, sekudya, zvinodiwa zvezuva nezuva, etc. Inogona kupa kuchengetedzwa kwakanaka kwekuita apo ichiratidza kutaridzika kwechigadzirwa.
Shangu zvinhu munda
Sole: EVA ine hunhu hwekupfava, hunyoro hwakanaka, huremu huremu, kupfeka kuramba, nezvimwe, ndicho chinhu chakanakira kugadzira chete. Iyo yega yakagadzirwa neEVA yakagadzika kupfeka, ine yakanaka kunyura kuita, uye inogona kuderedza kuneta kwetsoka.
Kumusoro: EVA inogonawo kushandiswa kugadzira zvigadzirwa zvepamusoro, zvichipa kubata kwakapfava uye kufema kwakanaka, zvichiita kuti shangu dzive dzakasununguka uye dzakanaka.
Kupisa kunyunguduka kunama munda
EVA hot melt adhesive: ine zvakanakira viscosity yakasimba, kukurumidza kurapa, yakaderera tembiricha kuramba, nezvimwewo, inoshandiswa zvakanyanya mukurongedza, kusunga, kugadzira fenicha uye mamwe maindasitiri. Inogona kushandiswa kubatanidza mapepa, huni, mapurasitiki uye zvimwe zvinhu, zviri nyore kushanda, zvinogona kuvandudza kugadzirwa kwakanaka.
Waya netambo yemunda
Insulation layer: EVA ine yakanaka insulation performance, kudzivirira kwemvura uye makemikari ekudzivirira kupisa, inogona kushandiswa seyekudzivirira layer zvinhu zvewaya uye tambo, inogona kunyatso chengetedza waya netambo kubva kusimba rekunze kwezvakatipoteredza, kuve nechokwadi chekuchengetedza uye kuvimbika kwekufambisa kwesimba.
Sheath: EVA inogona zvakare kushandiswa kugadzira sheath yewaya uye tambo, ichipa mechanical kuchengetedza uye anti-kuchembera kuita, kuwedzera hupenyu hwebasa rewaya netambo.
Mimwe minda
Matoyi: EVA yakapfava, haina chepfu, haina hwema uye humwe hunhu, hunowanzo shandiswa kugadzira matoyi, senge matoyi evana mabhora, mapuzzle, nezvimwewo, kuve nechokwadi chekuchengetedza uye kunyaradza kwekushandiswa kwevana.
Zvigadzirwa zvemitambo: Inoshandiswawo zvakanyanya mumidziyo yemitambo, senge mitambo MATS, yoga MATS, nezvimwewo, iyo kupfava uye elasticity inogona kupa rutsigiro rwakanaka uye cushioning mhedzisiro.
Zvigadzirwa zvefuro: EVA foam ine huremu huremu, yakapfava, inochengetedza kupisa, inovhara ruzha uye zvimwe zvivakwa, inogona kushandiswa kugadzira akasiyana emhando yezvigadzirwa zvefuro.
