Maitiro ekuongorora kana maitiro ekugadzira eVA bhegi ane hushamwari zvechokwadi?

Maitiro ekuongorora kana maitiro ekugadzira eVA bhegi ane hushamwari zvechokwadi?
Mumamiriro ezvinhu anhasi ekuwedzera kuziva kwezvakatipoteredza, zvave kunyanya kukosha kuongorora kana nzira yekugadzira yeEVA masagainofarira zvakatipoteredza. Izvi zvinotevera nhevedzano yematanho uye zviyero zvinogona kutibatsira kunyatsoongorora hushamwari hwezvakatipoteredza hweEVA bag kugadzira maitiro.

1. Kushamwaridzana kwezvakatipoteredza kwezvinhu zvakasvibiswa
Chekutanga, isu tinofanirwa kufunga nezvekuti zvinhu zveEVA bag zvine hushamwari zvakatipoteredza. EVA zvinhu pachazvo hazvisi-chepfu uye zvisingakuvadze zvakatipoteredza zvine hushamwari zvinhu. Munguva yekugadzira, inofanirwa kuve nechokwadi kuti iyo EVA zvinhu haina zvinhu zvinokuvadza uye inoenderana neakakodzera mamiriro ezvakatipoteredza uye mirau. Pamusoro pezvo, zvekushandisa zveEVA zvinofanirwa kuenderana nezviyero zvepasi rese seRoHS Directive uye REACH Regulation, iyo inorambidza kushandiswa kwezvinhu zvine njodzi uye inoda kushandiswa kwakachengeteka kwemakemikari.

2. Kushamwaridzana kwezvakatipoteredza kwemaitiro ekugadzira
Iyo yekugadzira bhegi yeEVA zvakare ine yakakosha kukanganisa kushamwaridzana kwayo kwezvakatipoteredza. Maitiro ekugadzira anosanganisira matanho akadai sekugadzirira zvinhu zvakasvibirira, kupisa kupisa kuumba, uye kudhinda. Mumaitiro aya, matekinoroji uye nzira dzinoenderana nenharaunda dzinofanirwa kushandiswa kuderedza kushandiswa kwesimba uye kugadzirwa kwemarara. Semuyenzaniso, kudzora tembiricha panguva yekupisa kuumba kuumba kwakakosha pakuchengetedza simba uye kuderedza kuburitswa kwemarara.

3. Kuraswa kwemarara uye kudzokorora
Kuongororwa kwehushamwari hwezvakatipoteredza hweEVA bhegi yekugadzira bhegi inodawo kutariswa kwekurapwa kwemarara uye matanho ekudzokorora. Marara anogadzirwa panguva yekugadzira anofanirwa kudzokororwa zvakanyanya sezvinobvira kuderedza kukanganisa kwezvakatipoteredza. Semuenzaniso, kuburitswa uye kurapwa kwe "marara matatu" eEVA mudziyo, kusanganisira kurapwa kwemvura yakasviba, gasi remarara uye tsvina yakasimba, inofanirwa kusangana nekuchengetedzwa kwezvakatipoteredza.

4. Hupenyu Cycle Assessment (LCA)
Kuita a life cycle assessment (LCA) inzira yakakosha yekuongorora maitiro ezvakatipoteredza emabhegi eEVA. LCA inonyatso ongorora maitiro ehurongwa hwese hwekurongedza pane zvakatipoteredza kubva kuunganidzwa kwezvinhu zvakasvibirira, kugadzira, kushandiswa kutambisa kurapwa. Kuburikidza neLCA, tinogona kunzwisisa kurema kwezvakatipoteredza kwemabhegi eEVA mukati mehupenyu hwavo hwese uye kutsvaga nzira dzekudzikisa nharaunda.

5. Mamiriro ezvakatipoteredza uye chitupa
Kugadzirwa kwemabhegi eEVA kunofanirwa kutevedzera zvimiro zvemumba uye zvepasirese zvakatipoteredza, senge China's yenyika zviyero GB/T 16775-2008 "Polyethylene-vinyl acetate copolymer (EVA) zvigadzirwa"
uye GB/T 29848-2018, iyo inotsanangura zvinodikanwa zvezvinhu zvemuviri, makemikari zvivakwa, kugadzira tekinoroji uye zvimwe zvinhu zveEVA zvigadzirwa. Uye zvakare, kuwana certification yezvakatipoteredza, senge ISO 14001 Environmental Management System certification, irevo yakakosha yekuongorora hushamwari hwezvakatipoteredza hweEVA bhegi kugadzirwa.

6. Kuita kwechigadzirwa uye kugadzirisa kwezvakatipoteredza
EVA mabhegi anofanirwa kuve neakanaka emuviri zvimiro, zvinopisa zvimiro, makemikari zvimiro uye nharaunda inochinja. Izvi zvinodikanwa zvekuita zvinovimbisa kuti bhegi reEVA rinogona kuchengetedza basa rayo panguva yekushandiswa, uku richikwanisa kudzikisira kana kudzokorodza munzvimbo yechisikigo kuderedza kukanganisa kwezvakatipoteredza.

7. Kuziva kwezvakatipoteredza uye mutoro wekambani
Chekupedzisira, kuziva kwezvakatipoteredza uye mutoro wemagariro emabhizinesi zvakare zvinhu zvakakosha mukuongorora hushamwari hwezvakatipoteredza hweEVA bhegi rekugadzira maitiro. Mabhizinesi anofanirwa kushingaira kuvandudza ruzivo rwavo rwekuchengetedzwa kwezvakatipoteredza uye mutoro wemagariro uye kusimudzira budiriro inoenderera. Kuburikidza neyakasvibira EVA nzira, mabhizinesi anogona kuvandudza mashandiro awo achiteerera kuchengetedza kwezvakatipoteredza

Muchidimbu, kuongorora kana kugadzirwa kwebhegi reEVA kunoenderana nemamiriro ekunze kunoda kutariswa kwakadzama kwezvinhu zvakawanda senge zvigadzirwa, maitiro ekugadzira, marapirwo emarara, kuongorora kutenderera kwehupenyu, mwero wezvakatipoteredza, kuita kwechigadzirwa uye mutoro wekambani. Kuburikidza nematanho aya, tinogona kuve nechokwadi chekuti maitiro ekugadzira emabhegi eEVA anosangana nezvinodiwa zvekuchengetedzwa kwezvakatipoteredza uye kubatsira mukuchengetedza nharaunda.
