Njengesisetshenziswa esibalulekile esiwusizo sezolimo zesimanje nokuphathwa kwemvelo kwangaphandle, amanetha anomthunzi abonisa izici ezihlukile ekulawuleni ukukhanya nokushisa, ukuvikelwa kwemvelo, kanye nokusetshenziswa kwezinsiza ngenxa yomklamo wawo ohlukile wesakhiwo kanye nezinzuzo zokusebenza kwawo. Lezi zici zisukela ekuthuthukisweni kwesayensi yezinto futhi zibonisa ukuphishekela okuphelele kokusebenza okuningi nomnotho ezinhlelweni zobunjiniyela.
Okokuqala, ukukhanya okunembile nokuguquguqukayo nokulawula ukushisa. Ngokulungisa ukuminyana kwemeshi nombala, amanetha anomthunzi angafinyelela ukugreda okunembile kwamazinga omthunzi phakathi kuka-30% no-90%, ahlangabezane nezidingo zamandla okukhanya ezihlukanisiwe zezitshalo noma izimo ezihlukahlukene. Inetha-enombala omnyama inezinga eliphezulu lokufiphaza kanye nokumunca ukushisa okuphawulekayo, kulungele{5}}izinkathi zokushisa eziphezulu ezidinga ukupholisa ngokushesha; ukukhanya-okunombala noma okusiliva{7}}okumpunga okukhanyayo kungabonisa imisebe ye-infrared ne-ultraviolet, enciphisa ingcuphe yokushiswa yilanga ngenkathi ipholisa. Ifomu layo lokumboza eliguquguqukayo livumela ukulungiswa ngokuya kwesikhathi sonyaka kanye nesigaba sokukhula kwezitshalo, okuvumela ukuphathwa kwemvelo okunamandla.
Okwesibili, ukuguquguquka okuqinile kwemvelo. Impahla eyinhloko ngokuvamile iphezulu-i-polyethylene (i-HDPE) ephezulu noma i-linear low-i-polyethylene e-density (LLDPE), ekwazi ukumelana nesimo sezulu esihle kakhulu kanye nezindawo zokulwa-nezindawo zokuguga, ezivumela{4}}ukusetshenziswa ngaphandle{4}}isikhathi eside ngaphandle kokuba brittle noma ukuphuka kalula. Eminye imikhiqizo ibhekana ne-UV-ukumelana, umswakama{7}}ukumelana nokushisa, kanye nokulungiswa okungasheshi ukuvutha{8}}, igcina ukuqina kwesakhiwo ngaphansi kwezimo zezulu eziyinkimbinkimbi njengesifutho sikasawoti wasogwini,{9}}imisebe enamandla ephezulu, noma izimo zemvula nezinomswakama, nempilo yesevisi ngokuvamile efinyelela iminyaka engu-2-4.
Okwesithathu, izakhiwo ezithembekile zemishini. Isakhiwo esilukiweyo sinikeza inetha lomthunzi amandla amahle kakhulu okubamba nokudabula; Ukucaciswa okujwayelekile kungafinyelela amandla okudonsa amakhulu amaningana ama-Newtons ngamasentimitha angu-5, akwazi ukumelana nemimoya enamandla, imvula enkulu, nemithwalo yeqhwa, egcina ukumbozwa okuphelele. Imiphetho ivamise ukusebenzisa izinqubo zokusonta ezisontekile noma ezishisayo-ezincibilikayo, ezivimbela ngempumelelo ukugqashuka kwentambo kanye nokwenza ngcono ukuqina kukonke.
Okwesine, ayisindi, iyaphatheka, futhi iyavumelana nezimo ekufakweni. Inetha ayisindi futhi iyagoqeka, isiza ezokuthutha kanye{1}}nokufakwa kusayithi, isekela ukumbozwa ngokushesha kwama-span amakhulu noma izindawo ezinomumo ongajwayelekile. Ukufakwa kungaqedwa kusetshenziswa isikafula, amakholomu, noma izigxobo zesikhashana ngaphandle kwezakhiwo eziyinkimbinkimbi zokusekela, ukunciphisa ubunzima bokwakha kanye nezindleko zesikhathi. Iphinde isetshenziswe futhi, inciphisa ukumoshwa kwezinsiza.
Okwesihlanu, iyahambisana nezimo eziningi futhi iyasebenza ngokwezomnotho. Ngaphandle kokutshalwa kwezolimo, amanetha anomthunzi asetshenziswa kakhulu ekutshalweni kwezithombo zezimbali, emashedi okufuywa kwezilwane zasemanzini,{1}}indawo yokugcina umoya evulekile, ukuvikela indawo yokwakha, nezindawo zokungcebeleka zomphakathi, ehlinzeka ngemisebenzi efana nokupholisa, ukugcinwa komswakama, ukuvikela isichotho, nokuhlelwa kwezwe. Izindleko zayo zokukhiqiza ziphansi uma kuqhathaniswa, nenzuzo ephezulu ekutshalweni kwezimali, ehambisana nezidingo zokuthuthukiswa kokukhiqizwa okuluhlaza nokongiwa kwamandla.
Kafushane, amanetha anomthunzi, anezici zawo eziyinhloko zokulawula ukukhanya okunembile, ukumelana nesimo sezulu esiphezulu, amandla nokuqina, ukuguquguquka okungasindi, nokusebenziseka okubanzi, akha umgoqo oguquguqukayo ongenziwa ngokwezifiso futhi osebenziseka kabusha, ahlinzeke ngosekelo oluthembekile lobuchwepheshe lokuthuthukisa ikhwalithi nokusebenza kahle kwezolimo zesimanje kanye nokuphathwa okuzinzile kwendawo yangaphandle.
