Ukuthintela njani isibane seplastiki ukuba sijike sibe tyheli kwaye sibe brittle

Ngaba udiniwe isibane sakho seplastiki sijika sibe tyheli kwaye sibe brittle ekuhambeni kwexesha? Lo mcimbi wepaki uhlala ubangelwa kukwandisa ixesha elide kubushushu obuphezulu, ukukhanya kwelanga, kunye nemitha ye-ultraviolet, ekhokelela ekuvuthweni kwezinto zeplastiki. Ukujongana nale ngxaki, uvavanyo lwe-ultraviolet ngumlinganiselo obalulekileyo wokuqinisekisa ukuhlala kunye nokuphila ixesha elide kweemveliso zeplastiki.

uvavanyo lwe-ultraviolet luxelisa imiphumo ye-ultraviolet beam kwizinto zeplastiki, vumela umenzi alinganise amandla okuvuthwa, ukuqhekeka, ukugqwetheka, kunye nebala. Ngokuxhomekeka kwintengiso ekukhanyeni kwe-ultraviolet ixesha elide, ulingo lunokulinganisa ngokuchanekileyo impembelelo yokuvezwa ngaphandle. Umzekelo, iveki enye yovavanyo lwe-ultraviolet ilingana nonyaka omnye wokuvezwa kukukhanya kwelanga, ukubonelela ngokungena okubalulekileyo ekusebenzeni kwentengiso ekuhambeni kwexesha.

Ukuqhuba uvavanyo lwe-ultraviolet kubandakanya ukubeka ukuthengisa kwisixhobo sovavanyo olukhethekileyo kwaye sibonakalise ukukhulisa ukukhanya kwe-ultraviolet.. Ngokunyusa amandla e-ultraviolet ngamaxesha angama-50 kwidigri yokuqala, umenzi unokukhawulezisa inkqubo yokuvuthwa kunye nokulinganisa ukomelela kwentengiso phantsi kweemeko ezinzima. Emva kovavanyo olungqongqo lweeveki ezintathu ze-ultraviolet, olulingana nobudala obuthathu bokukhanya kwelanga imihla ngemihla, uhlolo olucokisekileyo lwentengiso luqhutywa ukulinganisa naluphi na utshintsho ku-elasticity kunye nenkangeleko. Ngokuphumeza umlinganiselo ongqongqo wolawulo lomgangatho, njengovavanyo olungenamkhethe lwe-20 % yebhetshi ye-odolo nganye, umenzi unokuqinisekisa umgangatho ongaguqukiyo weemveliso zabo zeplastiki.

ukuqondaiindaba zoshishino:

iindaba zoshishino zidlala indima ebalulekileyo ekugcineni umntu enolwazi malunga nophuhliso lwamva nje, umkhwa, kunye nomngeni kwindalo yonke. Ngokuhlala unolwazi ngohlaziyo lwemarike, ingxelo yezemali, kunye nohlalutyo lweshishini, umfundi unokwazisa ngesigqibo malunga notyalo-mali, iskimu soshishino, kunye notyekelo lwezoqoqosho. Nokuba ungusomashishini wexesha okanye ungumtyali-mali osakhasayo, hlala unolwazi malunga neendaba zeshishini yimfuneko kuhambo olunzima kunye nokuziphatha okunamandla kurhwebo lwehlabathi.
