Kushandiswa

Ethylene-vinyl acetate copolymer CAS 24937-78-8 (EVA) ine mashandisirwo akasiyana-siyana, anotevera ndiwo mashandisirwo ayo makuru:

Munda wefirimu wakatetepa

Firimu rekurima: EVA ine chiedza chakanaka, inochengetedza kupisa uye inodzivirira mamiriro ekunze, uye inowanzoshandiswa mukugadzira firimu rekurima. Inogona kuchengetedza tembiricha nehunyoro mugreenhouse, kukurudzira kukura kwezvirimwa, uye kuwedzera hupenyu hwebasa refirimu.

Firimu rekurongedza: Firimu reEVA rine kuchinjika kwakanaka, kujeka uye kuramba kubhoorwa, rakakodzera kurongedza zvigadzirwa zvakasiyana-siyana, zvakaita sechikafu, zvinodiwa zuva nezuva, nezvimwewo. Rinogona kupa dziviriro yakanaka uku richiratidza chitarisiko chechigadzirwa.

Munda wezvishongedzo zveshangu

Sole: EVA ine hunhu hwekupfava, kupfava kwakanaka, huremu hwakareruka, kuramba kupfeka, nezvimwewo, ndiyo chinhu chakanakira kugadzira sole. Sole yakagadzirwa neEVA inopfava kupfeka, ine simba rakanaka rekunyudza shock, uye inogona kuderedza kuneta kwetsoka.

Kumusoro: EVA inogona kushandiswawo kugadzira zvinhu zvepamusoro, zvichiita kuti bhutsu dzinyatsobata zvakanaka uye dzikwanise kufema zvakanaka, zvichiita kuti shangu dzive dzakanaka uye dzigadzikane.

Munda wechinamatidza unopisa unonyunguduka

Chinonamira chinonyunguduka cheEVA: chine zvakanakira zvekusimba kwakasimba, kupora nekukurumidza, kusapisa zvakanyanya, nezvimwewo, chinoshandiswa zvakanyanya mukurongedza, kusunga, kugadzira fenicha nedzimwe nzvimbo. Chinogona kushandiswa kubatanidza mapepa, huni, mapurasitiki nezvimwe zvinhu, chiri nyore kushandisa, uye chinogona kuvandudza mashandiro ekugadzira.

Waya netambo yemagetsi

Chidziviriro chekudzivirira: EVA ine simba rakanaka rekudzivirira kupisa, inodzivirira mvura uye inodzivirira ngura yemakemikari, inogona kushandiswa sechinhu chinodzivirira kupisa kwewaya netambo, inogona kudzivirira waya netambo zvinobudirira kubva mukukanganiswa nekunze, kuve nechokwadi chekuti kufambiswa kwesimba remagetsi kwakachengeteka uye kwakavimbika.

Chifukidziro: EVA inogona kushandiswawo kugadzira chifukidziro chewaya netambo, ichipa dziviriro yemakanika uye simba rekudzivirira kukwegura, zvichiita kuti waya netambo zvirambe zvichishanda kwenguva refu.

Mimwe minda

Matoyi: EVA yakapfava, haina chepfu, haina hwema uye ine zvimwe zvinhu, inowanzoshandiswa kugadzira matoyi, akadai semabhora ematoyi evana, mapuzzle, nezvimwewo, kuitira kuti vana vagare vakachengeteka uye vakasununguka kushandisa.

Zvishandiso zvemitambo: Inoshandiswawo zvakanyanya muzvishandiso zvemitambo, zvakaita seMATS emitambo, yoga MATS, nezvimwewo, izvo kupfava uye kutwasuka kwazvo zvinogona kupa rutsigiro rwakanaka uye mhedzisiro yekutsvedza.

Zvigadzirwa zvefuro: Furo reEVA rine huremu hushoma, rakapfava, rinochengetedza kupisa, rinodzivirira ruzha nezvimwe zvinhu, rinogona kushandiswa kugadzira zvigadzirwa zvakasiyana-siyana zvefuro.
