Njengesixhobo esiqhelekileyo sokupakisha,iingxowa zeplastiki ezilukiweyozisetyenziswa kakhulu kubomi bemihla ngemihla. Nangona kunjalo, abantu abaninzi baye badibana nengxaki yeengxowa zeplastiki ezilukiweyo ezibuthathaka nezibuthathaka. Izizathu eziphambili zengxaki ziza kwaziswa ngezantsi, kwaye ezinye izisombululo ziya kubonelelwa ukusinceda sandise ubomi beengxowa zeplastiki ezilukiweyo.
Ingxowa elukiweyo yeplastiki luhlobo lwengxowa eyenziwe ngemicu yeplastiki efana ne-polypropylene (PP). Nangona inokumelana nokukrala okuphezulu kwaye inamandla okutsalwa, ngamanye amaxesha sifumanisa ukuba iyaqhekeka kwaye yaphuke lula. Oku kwenzeka ngenxa yezizathu ezahlukeneyo, kwaye nazi ezinye zezizathu eziphambili.
1. Ukukhanyisa
Xa ingxowa yeplastiki elukiweyo ivezwa lilanga, ipolymer ekuyo iya kuqhekeka kancinci kancinci, nto leyo ebangela ukuba ingxowa ibe buthathaka. Imitha ye-UV evezwa ngqo kumphezulu wengxowa evela elangeni inokubangela ukuba imixokelelwane yepolymer iqhekeke, nto leyo ebangela ukuba iplastiki ilahlekelwe ngamandla ayo okuqala kunye nokuguquguquka.
Isisombululo: Kuphephe ukubeka ingxowa yeplastiki elukiweyo elangeni ngqo ixesha elide, kwaye zama ukuyigcina okanye ukuyisebenzisa kwindawo epholileyo, enomthunzi.
2. Ukuxuba i-oxidation
Ioksijini ikwayenye yezizathu zokwaluphala kunye nokubuthathaka kweengxowa zeplastiki ezilukiweyo. Iimolekyuli zeoksijini zinokuqhekeza imixokelelwane yepolymer, ngoko ke ulwakhiwo lweemolekyuli zengxowa luyatshintsha kancinci kancinci, nto leyo eyenza ukuba ibe buthathaka.
Isisombululo: Gcina iingxowa zeplastiki ezilukiweyo kwindawo evaliweyo nengenamoya ukuze unciphise ukudibana kwengxowa nomoya kwaye uncede ekunciphiseni isantya apho ingxowa inyibilika khona.
3. Amaqondo obushushu aphantsi
Amaqondo obushushu aphantsi anokwenza iingxowa zeplastiki ezilukiweyo zibe buthathaka kwaye zibe buthathaka. Kumaqondo obushushu aphantsi, intshukumo yeemolekyuli zeplastiki iyacotha, inciphise ukuguquguquka kwengxowa, nto leyo ekhokelela kumngcipheko omkhulu wokuqhekeka nokuqhekeka.
Isisombululo: Kuphephe ukushiya ingxowa yeplastiki elukiweyo kwindawo ebanda kakhulu kwaye uzame ukuyisebenzisa kubushushu begumbi. Kwiindawo ezinobushushu obuphantsi ekufuneka zisetyenziswe, khetha iingxowa zeplastiki elukiweyo ezinokuguquguquka nokusebenza okungcono.
4. Izinyibilikisi zeekhemikhali
Iingxowa zeplastiki ezilukiweyo zihlala zichatshazelwa zizinto ezinyibilikisa iikhemikhali, ezifana notywala, izinto zokucoca ezine-asidi, njl.njl., ezinokutshabalalisa ulwakhiwo lweplastiki, zinciphise amandla ayo oomatshini, kwaye zonyuse umngcipheko wokuqhekeka nokuqhekeka.
Isisombululo: Kuphephe ukubeka iingxowa zeplastiki ezilukiweyo kwizinyibilikisi zeekhemikhali kwaye zama ukukhetha ingxowa efanelekileyo yokugcina izinto ezinokuba yingozi.
Ukuze sandise ubomi benkonzo yeengxowa zeplastiki ezilukiweyo, kufuneka siziqonde ngokupheleleyo izizathu ezibangela ukuba zibe buthathaka kwaye zibe buthathaka, size sithathe izisombululo ezifanelekileyo. Ukusetyenziswa nokugcinwa ngokufanelekileyo, ukuphepha ukuvezwa elangeni ngqo, ukunciphisa ukudibana nomoya, ukuphepha ukudibana neendawo ezinobushushu obuphantsi kunye nezinyibilikisi zeekhemikhali zonke ngamanyathelo abalulekileyo okukhusela iingxowa zeplastiki ezilukiweyo.
Ukongeza, kukho amanyathelo ongezelelweyo anokuthathwa ukwandisa ubomi beengxowa zeplastiki ezilukiweyo:
1. Ukusetyenziswa nokuphathwa ngendlela efanelekileyo: Kuphephe ukufaka izinto ezinzima kakhulu okanye ezibukhali kakhulu kwingxowa yeplastiki elukiweyo, ukuze ungandisi umthwalo ebhegini okanye ubangele ukuba umzimba wengxowa ukrweleke. Kwangaxeshanye, musa ukurhuqa ingxowa yeplastiki elukiweyo emhlabeni ukuze unciphise ukuguguleka kwengxowa zizinto zangaphandle.
2. Ukucoca nokulungisa rhoqo: Coca ingxowa elukiweyo yeplastiki rhoqo, ungasebenzisa amanzi athambileyo anesepha okanye isepha yokuhlamba impahla ukucoca umphezulu wengxowa, kwaye uyihlambe kakuhle. Ukugcina ingxowa icocekile kunokunciphisa ukukhukuliseka kweplastiki bukungcola kunye neekhemikhali ezinamathela kumphezulu.
3. Khetha iingxowa zeplastiki ezilukiweyo ezikumgangatho ophezulu: Xa uthenga iingxowa zeplastiki ezilukiweyo, khetha iimpawu kunye nezinto ezisemgangathweni othembekileyo nohlala ixesha elide. Iingxowa ezisemgangathweni ophezulu ziyakwazi ukumelana nokuguga nokuqhekeka, kwaye zinokugcina umgangatho olungileyo ixesha elide.
4. Cinga ngezinye iindlela ezinokubola: Ukunciphisa impembelelo kwindalo esingqongileyo, cinga ngokusebenzisa iingxowa zeplastiki ezibolileyo ezibolileyo endaweni yeengxowa zeplastiki zemveli. Iingxowa ezibolayo zinokonakala ngokukhawuleza, nto leyo enciphisa imiba yongcoliseko lweplastiki.
Ngokuthatha la manyathelo angasentla, ungandisa ubomi benkonzo yeengxowa zeplastiki ezilukiweyo kwaye unciphise ingxaki yokuqhekeka nokuqhekeka. Kwangaxeshanye, kufuneka sikhuthaze uphuhliso lwezisombululo zokupakisha ezinobuhlobo nokusingqongileyo nezizinzileyo, sinciphise imfuneko yeengxowa zeplastiki ezilukiweyo, kwaye sibe negalelo kwindalo esingqongileyo.
