Indlela yokuqinisekisa ukuba izinto zeplastiki aziyi kujika zityheli okanye ziphuke?
Isibane seplastiki sasimhlophe kakhulu kwaye sikhazimle ekuqaleni, kodwa sathi chu sajika sajika sajika sajika rhabaxa, nto leyo eyayisenza ukuba singabonakali kakuhle!
Usenokuba nale meko ekhaya. Isibane sesibane seplastiki phantsi kokukhanya sijika ngokulula sibe tyheli kwaye sibe brittle.
Ingxaki yezibane zeplastiki ezijika zibe tyheli kwaye zibe brittle zinokubangelwa kukuvezwa kwexesha elide kumaqondo obushushu aphezulu kunye nokukhanya kwelanga, okanye ukuvezwa kwimitha ye-ultraviolet, ebangela ukuba iplastiki iguge.
Uvavanyo lwe-UV lulinganisa ukuvezwa kwemitha ye-ultraviolet kwiplastiki ukuvavanya ukuba iindawo zeplastiki zemveliso ziya kuguga, ziqhekeke, zigqwethe, okanye zijike zibe tyheli.
Uluqhuba njani uvavanyo lwe-UV?
Okokuqala, kufuneka sibeke imveliso kwisixhobo sovavanyo kwaye emva koko sikhanyise ukukhanya kwethu kwe-UV.
Okwesibini, ukukhulisa amandla okukhanya malunga namaxesha angama-50 ubukhulu bayo bokuqala. Iveki enye yokuvavanywa ngaphakathi kwesixhobo ilingana nonyaka omnye wokuvezwa kwimitha ye-UV ngaphandle. Kodwa ityala lethu lathatha iiveki ezintathu, nto leyo ephantse yalingana neminyaka emithathu yokuba sesichengeni selanga elithe ngqo.
Ekugqibeleni, yenza uhlolo lwemveliso ukuqinisekisa ukuba kukho naluphi na utshintsho kwi-elasticity kunye nokubonakala kwamalungu eplastiki. Siya kukhetha ngokungakhethiyo i-20% yebhetshi nganye yee-odolo zokuvavanya ukuqinisekisa umgangatho wemveliso.
