Iingxowa zeplastiki esizisebenzisa ngokungaqhelekanga yonke imihla zibangele iingxaki ezinzulu kunye nomthwalo kwindalo.
Ukuba ufuna ukutshintsha iingxowa zeplastiki ngokubanzi ngokukhetha ezinye "ezinokonakala" iingxowa zeplastiki, ezi ngcamango zilandelayo malunga neengxowa zeplastiki ezinokonakala ziya kukunceda wenze ukhetho olufanelekileyo lokusingqongileyo!
Mhlawumbi ufumanise ukuba kukho "iingxowa zeplastiki ezonakeleyo" kwimarike.Unokucinga ukuba iingxowa zeplastiki ezinegama elithi "degradable" kufuneka zihlanjululwe kwaye zihambelane nokusingqongileyo.Nangona kunjalo, oku akunjalo.Okokuqala, kuphela xa iingxowa zeplastiki zinokuthi ekugqibeleni zibe zizinto ezingangcolisi ezifana namanzi kunye nekharbon diokside, zinokuthi zibe ziingxowa ezinobume bendalo.Kukho ubukhulu becala iintlobo ezininzi zeengxowa zeplastiki “ezinobuhlobo ngokusingqongileyo” kwimarike: iingxowa zeplastiki ezonakeleyo, ingxowa enokubola, kunye nengxowa evundisiweyo.
Ipolymer ekwingxowa yeplastiki yonakele ngokuyinxenye okanye ngokupheleleyo ngenxa yemitha ye-ultraviolet, i-oxidation corrosion, kunye ne-biological corrosion.Oku kuthetha utshintsho kwiipropathi ezifana nokuncipha, ukuqhekeka komphezulu, kunye nokuqhekeka.Inkqubo ye-biochemical apho i-organic matter kwiingxowa zeplastiki iguqulwa ngokupheleleyo okanye iyingxenye emanzini, i-carbon dioxide / methane, amandla kunye ne-biomass entsha phantsi kwesenzo se-microorganisms (iibhaktheriya kunye nefungi).Izingxobo zeplastiki zinokonakaliswa phantsi kweemeko ezikhethekileyo kunye nesikali sexesha lemihlaba yobushushu obuphezulu, kwaye ngokuqhelekileyo zifuna ukuvundisa kwimizi-mveliso ukuze kuphunyezwe ukusebenza kakuhle kokuthotywa komgangatho.
Ngokwale mbono mithathu ingentla, kuphela ziingxowa ezinokubola okanye ezivundisiweyo “ezilukhuseleko lokusingqongileyo” ngokwenene!
Uhlobo lokuqala lweengxowa zeplastiki "ezinokonakala" ngokukodwa zibandakanya "i-photodegradation" okanye "i-oxygen degradation ye-thermal. Ekugqibeleni, banokujika kuphela iingxowa zeplastiki zibe ngamaqhekeza amancinci, angenakulungele ukuphinda kusetyenziswe kunye nokucocwa kweeplastiki, kodwa kunye nokuhlukana. iiplastiki Ukungena kwimo engqongileyo kuya kubangela iingxaki ezingakumbi zongcoliseko.Ngoko ke, le ngxowa yeplastiki “eyonakaliswayo” ayinabungozi kokusingqongileyo, kwaye ikwabangele inkcaso enkulu kolu shishino.
Iiplastiki ezifotweyo: iiplastiki ezonakaliswe kukukhanya kwendalo;ukukhanya kungokwasemitha ye-ultraviolet, enokubangela kuphela umonakalo ongaphelelanga okanye opheleleyo kwipolymer.
Iiplastiki ze-Thermal oxidative degradation: iiplastiki ezonakaliswa bubushushu kunye / okanye i-oxidation;ukuthotywa kwe-thermal-oxidative yeye-corrosion ye-oxidative, enokubangela kuphela umonakalo opheleleyo okanye opheleleyo kwi-polymer.Ke ngoko, funda ukwahlula iingxowa zeplastiki ezonakeleyo ezahlukeneyo kwimeko kaxakeka!
Izingxobo zeplastiki eziveliswe ngokusesikweni kufuneka ziphawulwe ngokungqinelana nemigangatho kunye nezinto ezisetyenzisiweyo.Phakathi kwazo: uphawu lokuphinda lusetyenziswe lubonisa ukuba isikhwama seplastiki sinokuphinda sisetyenziswe kwaye siphinde sisetyenziswe;I-04 kuphawu lokuphinda isetyenziswe luphawu olukhethekileyo lwedijithali lokuphinda lisetyenziswe kwi-polyethylene ephantsi (LDPE);phantsi kophawu lokurisayikilishwa> PE-LD< ibonisa imathiriyeli yokuvelisa iingxowa zeplastiki;"I-GB / T 21661-2008" kwicala lasekunene legama elithi "isikhwama sokuthenga iplastiki" ngumgangatho wokuvelisa othotyelwa yizikhwama zeplastiki.
Ngoko ke, xa uthengela isikhwama se-biodegradable okanye i-compostable bag, kufuneka uqale ukhangele ukuba kukho i-logo yeplastiki efunwa lilizwe phantsi kwesikhwama.Emva koko, gweba ngokwezixhobo zokuvelisa ingxowa yeplastiki phantsi kweleyibhile yokukhusela indalo.Izinto ezisetyenziswa ngokuqhelekileyo i-biodegradable okanye i-compostable bag materials yi-PLA, i-PBAT, njl.
Sebenzisa iplastiki esetyenzisiweyo kangangoko kwaye uzame ukuyisebenzisa kangangoko phambi kokuba uyilahle!
