Inetha lothango lwenkundla yebhola lezinyawo linezici zokunqanda ukugqwala, ukulwa nokuguga, ukumelana nelanga, ukumelana nesimo sezulu, umbala ogqamile, indawo enezikhala ezibushelelezi, ukungezwani okuqinile, okungathinteki ekuthintekeni nasekuguqukeni kwamandla angaphandle, ukwakhiwa nokufakwa endaweni, kanye nokuguquguquka okuqinile. Ngakho-ke lapho wenza inetha lokubiya enkundleni yebhola Yini okufanele uyinake lapho ufutha?
1. Lapho sifafaza uthango lwenkundla yebhola lezinyawo epulasitiki, sidinga ukuluphatha ngokucophelela futhi siyipakishe ukuze sigweme ukungqubuzana.
2. Uma sifutha inetha lothango lwenkundla yebhola, kufanele sigweme ukuvuza nokuconsa ngokulinganayo nangokucophelela.
3. Ngaphambi kokufafaza inetha lothango lwenkundla yebhola lezinyawo, ukuqhunyiswa kwesibhamu nokususwa kokugqwala kuyadingeka ukuze kuthuthukiswe ubuhwaqane obungaphezulu futhi kwandiswe ukunamathela phezulu kwempushana yepulasitiki.
Ngaphansi kwezimo ezijwayelekile, amanetha othango lwenkundla yebhola ikakhulukazi asebenzisa izindlela zokwelapha ezimbili: ukugoqa ipulasitiki ye-PVC noma i-PE. Uyini umehluko phakathi kwalezi zindlela ezimbili zokwelapha?
1. Izindlela ezihlukene zokwelapha ezingaphezulu zingasetshenziswa ukuhlangabezana nezidingo zamakhasimende ezihlukene. Ngokuvamile, impilo yesevisi yazo zombili izindlela zokwelapha ezingaphezulu ingafinyelela eminyakeni engu-5-10.
2. Ipulasitiki yokupakisha ye-polyethylene isetshenziswa kabanzi futhi inezindleko eziphansi, futhi ingahlangabezana nezidingo zocingo olujwayelekile lwenkundla yebhola. Kodwa-ke, i-PE plastic powder inokumelana okubuthakathaka kwe-UV futhi kulula ukufiphala noma ukuqhekeka.
3. Uthango lwenkundla yebhola olwenziwe ngepulasitiki yokupakisha ye-PVC lunamandla okumelana ne-UV futhi ungqimba lwepulasitiki luqine kakhulu. Ngokuvamile, ngeke kuqhekeke phakathi neminyaka eyishumi nanhlanu. Kodwa-ke, izindleko ze-PVC plastic powder ziphakeme kakhulu, eziphakeme kunaleyo ye-PE eshibhile. Intengo yezinto zokusetshenziswa eziyimpuphu yepulasitiki iphindwe kabili noma kathathu ngaphezulu, futhi ayisetshenziswa kakhulu kubanikazi abaningi abaqaphela izindleko.
