- Iimpawu zokusebenza
- Ulawulo lokhula Ukusebenza
- Ilaphu lokulawula ukhula lwePolyethylene linokuthintela ngempumelelo ukukhula kokhula. Lithintela ukukhanya kwelanga kwaye lithintele ukhula ekubeni luqhube i-photosynthesis, ukuze ukhula lungakwazi ukufumana amandla afunekayo ukuze lukhule luze lufe. Izinga lalo lokukhusela ukukhanya liphezulu, ngokubanzi lifikelela ngaphezulu kwama-90%, nto leyo enokubonelela ngendawo efanelekileyo yokulawula ukhula kwizityalo okanye kwizityalo zasegadini.
- Olu hlobo lwelaphu lokulawula ukhula lunokuthintela imbewu yokhula ekukhuleni komhlaba. Ngenxa yokuba igubungela umhlaba kwaye yenza umqobo, ithintela imbewu ekufikeleleni ngokupheleleyo emhlabeni kwaye ibe neemeko ezifanelekileyo zokukhanya, nto leyo enciphisa amathuba okukhula kokhula.
- Ukuqina
- Ngokuphathelele ukumelana nemozulu, ilaphu lokulawula ukhula lwe-polyethylene lisebenza kakuhle. Linokumelana neemeko ezahlukeneyo zemozulu, kubandakanya ukuvezwa lilanga, ukukhukuliseka kwemvula namanzi, utshintsho lobushushu, njl. Ngenxa yokongezwa kwezifunxi ze-ultraviolet, linokumelana ngempumelelo nempembelelo yokuwohloka kwemitha ye-ultraviolet ngexesha lokusetyenziswa ixesha elide ngaphandle kwaye landise ubomi benkonzo, ngokubanzi iminyaka emi-5 ukuya kweli-10.
- Ikwanayo nokumelana okuhle nokukrazuka nokukrweleka. Ngexesha lenkqubo yokubeka nokusetyenziswa kwayo, nokuba ichaphazeleka kukungqubana nokutsalwa kwayo ngaphandle, njengokuhamba kwabantu kunye nokusebenza kwezixhobo zasefama, akulula ukuba yonakale kwaye inokugcina imeko yokugquma iphelele kwaye iqhubeke nokusebenza njengolawulo lokhula.
- Ukuvunyelwa kwamanzi kunye nomoya
- Ilaphu lokulawula ukhula lwe-polyethylene linomngxuma othile wamanzi. Iimbobo okanye izakhiwo ezincinci ezenziwe ngexesha lenkqubo yokuvelisa zinokuvumela ukuba amanzi angene, nto leyo enokuqinisekisa ukuba umoya uyangena kunye nokulinganisela kwamanzi emhlabeni. Umzekelo, ngexesha lemvula, amanzi anokungena ngelaphu lokulawula ukhula aye emhlabeni, enika amanzi afunekayo kwiingcambu zezityalo, kwaye kwangaxeshanye, ayizukubangela ukuba amanzi angene emhlabeni, nto leyo eluncedo ekukhuleni kwezityalo.
- Ukungena komoya kukwanegalelo kwimisebenzi yeentsholongwane zomhlaba. Ukujikeleza komoya ngokufanelekileyo kunokwenza iintsholongwane eziluncedo emhlabeni zikwazi ukucola ngendlela eqhelekileyo, zibole izinto eziphilayo, zinike izondlo kwizityalo kwaye zigcine ulungelelwaniso lwendalo lomhlaba.
- Uzinzo lweeKhemikhali
- I-Polyethylene ngokwayo yinto ehlala izinzile ngokweekhemikhali. Iyakwazi ukumelana neekhemikhali ezininzi kwaye ayizukuchasana nezichumisi kunye nezibulali zinambuzane emhlabeni. Oku kwenza ukuba isetyenziswe ngokukhuselekileyo kwiindawo ezahlukeneyo zezolimo nezezityalo ngaphandle kokonakala okanye ukukhupha izinto eziyingozi ngenxa yempembelelo yeekhemikhali.
- Ulawulo lokhula Ukusebenza
