Eminyakeni yamuva nje, ukusetshenziswa kocingo lwepulasitiki olusetshenzisiwe kuye kwanda, kuvame ukudayiswa njengendlela eqhubekayo esikhundleni socingo lwezinkuni lwendabuko. Uma uqala ukubheka, kubonakala sengathi kuyisisombululo esiphelele - ukuguqula imfucuza ibe yinto ewusizo, ukunciphisa ukucindezeleka kwemithombo yemvelo, kanye nokunikeza inketho eqinile, engadingi ukunakekelwa okuningi kwemingcele yezindawo kanye nokusetshenziswa komgwaqo. Kodwa ingabe ucingo lwepulasitiki olusetshenzisiwe luyakwazi ukuhlolisiswa uma luqhathaniswa nokhuni maqondana nomthelela wemvelo?
Ake singene emininingwaneni ukuze sihlole ukuthi uthango lwepulasitiki olusetshenziswe kabusha lungcono ngempela yini endaweni ezungezile kunokhuni, noma ukuthi ukhuni luseyindlela enobungani nemvelo.
Izinkuni bezisetshenziswa njengezinto zokubiyela amakhulu eminyaka, futhi ngesizathu esihle. Uma zitholakala emahlathini aphethwe ngendlela eqhubekayo, izinkuni zingenye yezinto ezinakekela kakhulu imvelo ezitholakalayo. Izihlahla zimunca i-carbon dioxide emoyeni njengoba zikhula, zigcina i-carbon ngaphakathi kwemicu yazo. Lapho izinkuni zivunwa futhi zisetshenziselwa imikhiqizo efana nokubiyela, lelo khabhoni lihlala livalekile, lisiza ekunciphiseni amagesi okushisa ukushisa.
Ngaphezu kwalokho, izinkuni ziwumthombo ovuselelekayo. Uma nje izinkuni zivela emahlathini aphethwe ngendlela efanele asebenzisa amasu okutshala kabusha kanye nokugawula imithi ngendlela eqhubekayo, zingagcwaliswa njalo ngaphandle kokuqeda amahlathi. Imikhiqizo eminingi yezinkuni namuhla iza nezitifiketi eziqinisekisa ukuthi izinto zitholakale ngendlela enakekela imvelo kanye nezenhlalo.
Enye yezinzuzo ezinkulu ukhuni olunazo ngaphezu kwepulasitiki ephinde yasetshenziswa ukuthi lubola kalula ngokwemvelo. Ukhuni luzobola ngokuhamba kwesikhathi, lubuyisele izakhamzimba enhlabathini futhi lungashiyi mthelela omkhulu noma ohlala njalo emvelweni.
Ngokuphambene nalokho, ucingo lwepulasitiki olusetshenziswe kabusha lwenziwa ngezinto ezingaphuki ngokwemvelo. Nakuba kuyiqiniso ukuthi la mapulasitiki anikezwa impilo yesibili ngokusetshenziswa kabusha, ucingo ngokwalo lungagcina lusendaweni yokulahla udoti, lapho kungathatha amakhulu eminyaka ukubola. Kwezinye izimo, ucingo lwepulasitiki lungase lungaphinde lusetshenziswe futhi ekupheleni kokuphila kwalo, okwenza inkinga yemfucuza yepulasitiki ibe nzima kunokuba ixazululwe.
Ukubiyelwa ngokhuni kudinga ukucutshungulwa okuncane. Izihlahla ziyanqunywa, ziphathwe, futhi zibunjwe zibe yizinsika namaphaneli, konke kufakwa amandla aphansi uma kuqhathaniswa nokukhiqizwa kwepulasitiki.
Ngakolunye uhlangothi, inqubo yokwakha ucingo lwepulasitiki olusetshenziswe kabusha ihilela ukuqoqa, ukuhlunga, ukuhlanza, ukuncibilikisa, nokulungisa imfucuza yepulasitiki - inqubo edinga amandla amaningi. Nakuba lokhu kuguqula ipulasitiki ezindaweni zokulahla udoti, amandla adingekayo ukukhiqiza ucingo lwepulasitiki adlula kakhulu amandla adingekayo ukucubungula izinkuni.
Ngaphezu kwalokho, izinhlobo eziningi zocingo lwepulasitiki zidinga ukungezwa kweziqinisi zamakhemikhali, izivikelo ze-UV, kanye nemibala ukuze kuthuthukiswe ukuqina nokubukeka kwazo. La makhemikhali, kanye nezidingo zamandla zokukhiqizwa kwepulasitiki, anganciphisa ezinye zezinzuzo zemvelo zokusebenzisa izinto eziphinde zasetshenziswa.
Uma sibheka yonke imjikelezo yokuphila kwezinto zokubiyela, kusukela ekutholeni izinto kuya ekukhiqizeni kuya ekulahleni, ukhuni luhlala lubonakala luhlala isikhathi eside kunepulasitiki.
Ukubukeka nomuzwa wemvelo wokhuni kwenza kube ukukhetha okuhle kocingo ezindaweni zasemakhaya nasemadolobheni. Kodwa ngale kokubukeka kwalo, ucingo lokhuni luphinde lunikeze izinzuzo zemvelo. Njengezinto zemvelo, ukhuni aluphazamisi imvelo yendawo ngendlela efanayo nepulasitiki engase iphazamise ngayo. Eqinisweni, ucingo lokhuni lungasekela ngisho nokuhlukahluka kwezinto eziphilayo ngokunikeza izindawo zokuhlala zezinambuzane, izinyoni, nezilwane ezincane ezincelisayo.
Ngokuphambene nalokho, ucingo lwepulasitiki - nakuba luhlala isikhathi eside - lungangenisa amakhemikhali okwenziwa emvelweni, ikakhulukazi uma luqala ukuwohloka ngokuhamba kwesikhathi ngenxa yesimo sezulu esibi. Ipulasitiki nayo cishe ayinakusekela izilwane zasendle ngendlela efanayo nokhuni olungenza ngayo.
Abagqugquzeli bocingo lwepulasitiki olusetshenziswe kabusha bavame ukugqamisa ukuqina kwalo kanye nokunakekelwa okuphansi. Kuyiqiniso ukuthi ipulasitiki ayiboli, ayigobi, noma ayidonsi izinambuzane ngendlela ukhuni olungaphathwa ngayo. Kodwa-ke, ngokwelashwa okufanele, ucingo lwezinkuni lungahlala amashumi eminyaka ngokunakekelwa okuncane kuphela. Ukhuni oluphathwe ngokucindezela luvikelwe ezimweni zezulu futhi lungahlala lusesimweni esihle. Ukwengezwa kwesivikelo se- Postsaver +PLUS ground-line total barrier sleeve kuzoqinisekisa ukuthi lesi sivikelo sihlala iminyaka engama-40, isikhathi sokuphila esingatholakali ngezinye izindlela zepulasitiki.
Ipulasitiki, nakuba inganakekelwa kahle, ayivikeleki ngokuphelele ekushiseni. Ngokuhamba kwesikhathi, ukuchayeka emisebeni ye-UV kungabangela ukushintsha kombala, futhi ukwanda kokushisa emazingeni okushisa ahlukahlukene kungaholela ekugobekeni. Nakuba lezi zinkinga zingavami kakhulu kunezokhuni, zisekhona - futhi ucingo lwepulasitiki alukwazi ukulungiswa kalula njengokhuni. Ngokuvamile, ucingo lwepulasitiki olulimele ludinga ukuthi kushintshwe izingxenye eziphelele, okuholela ekufuthweni okwengeziwe kwezinto.
Kukhona futhi impikiswano engokomzwelo neyezomnotho esekela uthango lwezinkuni.
Izinkuni ziyinto yemvelo ehlangana kahle nezindawo zasemaphandleni kanye nezingadi zesimanje. Ziyinto eye yathenjwa amakhulu eminyaka futhi iyaqhubeka nokubaluleka ngenxa yokusimama kwayo nobuhle bayo.
Ngaphezu kwalokho, ukhuni luvame ukuba yindlela engabizi kakhulu. Nakuba ucingo lwepulasitiki olusetshenzisiwe lungaba nezindleko eziphezulu kusengaphambili, ukhuni luvame ukubiza kancane futhi lutholakala kalula, ikakhulukazi uma lutholakala endaweni.
Nakuba uthango lwepulasitiki olusetshenziswe kabusha lunikeza izinzuzo ezithile, ikakhulukazi maqondana nokuqina kanye nokusetshenziswa kabusha kwezinto ezilahliwe, ukhuni luhlala luyisinqumo esingcono kakhulu semvelo uma lutholakala ngendlela eqhubekayo. Uhlobo lwalo oluvuselelekayo, ukubola kwezinto eziphilayo, kanye nokusetshenziswa kwamandla aphansi ekukhiqizeni kwenza kube inketho enobungani kakhulu nemvelo yothango, ikakhulukazi uma kucatshangelwa umthelela wesikhathi eside wemvelo.
Kulabo abafuna ukunciphisa ukushaqeka kwekhabhoni yabo, ukusekela imvelo yendawo, kanye nokutshala imali emthonjeni ovuselelekayo, ukhuni luwumnqobi ocacile. Uma lutholakala ngendlela efanele, luphathwa isikhathi eside, futhi lugcinwa kahle, ucingo lokhuni alunikezi nje kuphela ikhambi elihlala isikhathi eside neliqhubekayo kodwa futhi lunikeza nobuhle obuthuthukisa ubuhle bemvelo bemvelo.
Empikiswaneni yokuthi ucingo lwepulasitiki olusetshenziswe kabusha lungaba ngcono yini emvelweni kunokhuni, impendulo icacile: ukhuni luhlala luyisinqumo esinomthwalo wemfanelo kakhulu emvelweni kulabo ababeka phambili ukusimama, ubuhle, kanye nenhlalakahle yeplanethi yethu.
Njengoba kunemikhiqizo engaphezu kwezigidi eziyi-10 ethengiswa kumakhasimende emhlabeni jikelele, i-Postsaver ingumkhiqizi ohamba phambili wemikhiqizo efakazelwe ukwandisa impilo yocingo lwezinkuni kanye nezinsika zesango.
