Kodi mungawunikire bwanji ngati kupanga chikwama cha EVA ndikogwirizana ndi chilengedwe?
Masiku ano pakuwonjezeka kwa chidziwitso cha chilengedwe, zakhala zofunikira kwambiri kuwunika ngati njira yopangiraEVA matumbandi wokonda zachilengedwe. Zotsatirazi ndi mndandanda wa masitepe ndi miyezo yomwe ingatithandize kuunika bwino momwe chilengedwe chimagwirira ntchito popanga thumba la EVA.
1. Environmental ubwenzi wa zipangizo
Choyamba, tiyenera kulingalira ngati zopangira za thumba la EVA ndizogwirizana ndi chilengedwe. Zida za EVA zokha ndizopanda poizoni komanso zosavulaza zachilengedwe. Panthawi yopanga, ziyenera kuwonetseredwa kuti zinthu za EVA zilibe zinthu zovulaza ndipo zimagwirizana ndi miyezo ndi malamulo oyendetsera chilengedwe. Kuphatikiza apo, zida za EVA ziyenera kutsata miyezo yapadziko lonse lapansi monga RoHS Directive ndi REACH Regulation, yomwe imaletsa kugwiritsa ntchito zinthu zowopsa ndipo imafuna kugwiritsa ntchito mankhwala mosamala.
2. Kugwirizana kwa chilengedwe pakupanga
Kapangidwe ka thumba la EVA kumakhalanso ndi chiwopsezo chachikulu paubwenzi wake wachilengedwe. Njira yopangirayi imaphatikizapo masitepe monga kukonzekera zopangira, kuumba kotentha kotentha, ndi kusindikiza. M'njirazi, umisiri ndi njira zoteteza chilengedwe ziyenera kugwiritsidwa ntchito kuchepetsa kugwiritsa ntchito mphamvu komanso kuwononga zinyalala. Mwachitsanzo, kuwongolera kutentha pakuwumba kotentha ndikofunikira pakupulumutsa mphamvu ndikuchepetsa kutulutsa zinyalala.
3. Kuchotsa zinyalala ndikubwezeretsanso
Kuwunika kwa chilengedwe cha njira yopangira thumba la EVA kumafunanso kuganizira zochotsa zinyalala ndi njira zobwezeretsanso. Zinyalala zomwe zimapangidwa panthawi yopanga zimayenera kubwezeretsedwanso momwe zingathere kuti zichepetse kuwonongeka kwa chilengedwe. Mwachitsanzo, kutulutsa ndi kuchiritsa "zinyalala zitatu" za chipangizo cha EVA, kuphatikizapo kuyeretsa madzi onyansa, mpweya wonyansa ndi zinyalala zolimba, ziyenera kukwaniritsa zofunikira zachitetezo cha chilengedwe.
4. Life Cycle Assessment (LCA)
Kuchita kafukufuku wa moyo (LCA) ndi njira yofunikira yowunika momwe matumba a EVA amagwirira ntchito. LCA imayang'ana mozama momwe njira yonse yopakira chilengedwe ikuyendera kuchokera kuzinthu zopangira, kupanga, kugwiritsa ntchito kuwononga mankhwala. Kudzera mu LCA, titha kumvetsetsa kuchuluka kwa matumba a EVA m'moyo wawo wonse ndikupeza njira zochepetsera chilengedwe.
5. Miyezo ya chilengedwe ndi chiphaso
Kupanga matumba a EVA kuyenera kutsata miyezo yapakhomo komanso yapadziko lonse lapansi, monga zinthu zaku China GB/T 16775-2008 "Polyethylene-vinyl acetate copolymer (EVA)"
ndi GB/T 29848-2018, zomwe zimafotokoza zofunikira pazakuthupi, katundu wamankhwala, ukadaulo wopanga ndi zina zazinthu za EVA. Kuphatikiza apo, kupeza chiphaso chachilengedwe, monga chiphaso cha ISO 14001 Environmental Management System, ndichinthu chofunikiranso pakuwunika kuyanjana kwachilengedwe pakupanga matumba a EVA.
6. Kuchita kwazinthu ndi kusinthasintha kwa chilengedwe
Matumba a EVA ayenera kukhala ndi mawonekedwe abwino, matenthedwe, katundu wamankhwala komanso kusinthika kwachilengedwe. Zofunikira zogwirira ntchitozi zimatsimikizira kuti thumba la EVA limatha kukhalabe ndi ntchito yake panthawi yogwiritsidwa ntchito, pomwe limatha kusokoneza kapena kukonzanso chilengedwe kuti lichepetse kukhudzidwa kwa chilengedwe.
7. Kudziwitsa za chilengedwe ndi udindo wa kampani
Pomaliza, kuzindikira kwachilengedwe komanso udindo wamabizinesi ndizofunikiranso pakuwunika momwe chilengedwe chimagwirira ntchito popanga zikwama za EVA. Mabizinesi akuyenera kupititsa patsogolo kuzindikira kwawo zachitetezo cha chilengedwe ndi udindo wa anthu ndikulimbikitsa chitukuko chokhazikika. Kupyolera mu njira yobiriwira ya EVA, mabizinesi amatha kuwongolera magwiridwe antchito ndikusamalira chitetezo cha chilengedwe
Mwachidule, kuwunika ngati kapangidwe ka thumba la EVA ndi kogwirizana ndi chilengedwe kumafuna kulingalira mozama za zinthu zingapo monga zopangira, njira zopangira, kukonza zinyalala, kuwunika kwa moyo, miyezo ya chilengedwe, magwiridwe antchito ndi udindo wamakampani. Kudzera munjira izi, titha kuwonetsetsa kuti kupanga matumba a EVA kumakwaniritsa zofunikira zachitetezo cha chilengedwe ndikuthandizira kuteteza chilengedwe.
