ifilimi yesebhedvo lesikhatsi

I-greenhouse film elishayi lavela ukuthi ngamandla ekupheleni kwisezulwini kwi-technology yegazela emoderni, ukuze kube ngekhetho olunqwenyana nokubheka okulandelakala kwesibhedlela sokugrowa. Le matrikhi wesicathulo esikhoyo zikusetyenziswa ngeminyaka engaphezulu polyethylene enkulu, uzokufaka amasitabili ezi-UV nokutekhnoloji lokuhlola isithoba lokuhlula ukuba kuhloniphe izidingo ezidingane zokugrowa. Ukukhambeka kwe-film kuningi phakathi kwe-100 nge-200 mikroni, ubungakanani bakhona ngaphandle kokuthi akhutshene ngendlela yokuhlula ngempawu ekupheleni kwe-91%. Ukhetho lokuhlala lokulandelakala kukusebenzisa ukuthi akhuphi amadropi amancamthi ahlale kumahlaba, ngakho kulandelayo amanye amagama amancamthi angavamile ngaphansi kwe-film. Imininingwane ye-infrared yakhiwo yakusebenza ukuthi akhuphi imigomo emidleni ngokushintsha umoya wokusebenza ngomhla omncane nakusebenzisa ukungavamile umoya ngalanga lwencane. Lefilmi lwegreenhouse lusetyenziswa ngokucacile ukuthi alandele ku-degradation kwechemicals egazela nokwe-UV radiation, uzokusihliselela usuku oluzinhloko 3-4 ngaphandle komncane ngokwesiphumo. Izibophelelo ezindala zayo zinengeziwe phakathi kwe-3 nge-14 mita, uzokwahlula ukuba kusetyenziswa ngokubanzi kwezistrakichi zesibhedlela, phakathi kwe-greenhouses ezincinci zokugcina nokwe-greenhouses ezincinci ezikhoyo. Imibiko yesiphumo sesifilmi sikhona ngokubanzi ukukhupha nokukhupha kakhulu, uzokwahlula ukuba kahle ukusetshenziswa ngokubanzi kwezinto ezisusiweyo zokudla ngaphandle kokuthi zimhlophe nokuhluke.

I-greenhouse film ethengiswayo inezinzuzo eziningi ezisebenzayo ezenza ibe utshalomali oluhle kakhulu kokubili kubalimi bezentengiselwano nabalimi bokuzilibazisa. Okokuqala nokubaluleke kakhulu, amandla ayo aphakeme okudlulisa ukukhanya aqinisekisa ukuthi izitshalo zithola amazinga amahle kakhulu okukhanya ukuze zisebenze kahle, zikhuthaze ukukhula okunempilo futhi zikhuphule isivuno. Izakhiwo zefilimu ezilwa nokuqina zivimbela ukuba kube namaconsi amanzi endaweni engaphakathi, kunciphise ingozi yezifo zezitshalo futhi kugcine ukukhanya kungena njalo. Izakhiwo zokushisa zalesi sakhi zenza ukonga okukhulu kwamandla ngokugcina amazinga okushisa azinzile ngaphakathi kwe-greenhouse, kunciphisa izindleko zokushisa ebusika kanye nezidingo zokupholisa ehlobo. Ukwakheka kwayo okuzinze nge-UV kwandisa isikhathi sokuphila kwefilimu, inikeze inani elihle kakhulu uma liqhathaniswa nezinto ezivamile zokumboza. Ukuguquguquka kwefilimu kwenza ukufakwa kube lula, kudinga imishini noma ulwazi oluncane olukhethekile. Ukutholakala kwayo ngobubanzi obukhulu kunciphisa inani lezingxenye ezidingekayo, kunciphisa izindawo ezingaba buthaka futhi kuthuthukise ukuqina kwesakhiwo jikelele. Ukumelana kwamakhemikhali kwale nto kuqinisekisa ukuhambisana kwayo namakhemikhali ajwayelekile ezolimo kanye nezinto zokuhlanza, okwenza ukugcinwa kube lula futhi kuphumelele. Ukumelana kahle kwefilimu nokugqwala kunciphisa imvamisa yokulungisa nokushintsha, okuholela ezindlekweni eziphansi zokusebenza esikhathini eside. Ngaphezu kwalokho, izakhiwo zayo zokusakaza ukukhanya zisiza ekwakheni indawo ekhulayo ngokulinganayo ngokusabalalisa ukukhanya ngokulinganayo kulo lonke ipulazi, kuvimbele izindawo ezishisayo futhi kuqinisekise ukukhula kwezitshalo okuqhubekayo. Ukukwazi kwalo ukumelana nesimo sezulu esibi kakhulu kunikeza ukuthula kwengqondo phakathi neziphepho nezimo zezulu ezimbi, kuvikele izitshalo eziyigugu nemishini engaphakathi.

Ukhuphelo Lwesintu lwamandla lweUV kwaye Ukuphatha Kwemali

Ukhuphelo Lwesintu lwamandla lweUV kwaye Ukuphatha Kwemali

Umbhulalo wethu wesikhathi lwenqaba luhlanganisa umthombo omphambili wase-UV olusetshenziswa ngokwesintu ukufinyelela amakhulu ezingazangekho kwindawo yokubala izinkomo. Izinhlobo ezithile zase-UV zinikwe emasimu aphakade ngenqaba, uzokusure yindawo yokugcina phakathi kwemibuzo engamukelanga imigama elingaphandle lolunqabane lwemibuzo olungahlukeleyo nokuhlola kwisezincwadi ezifaneleyo zomoya esetshenziswa ngokusebenza (PAR). Ukuthi lokungena okusetyenziswa kunikeza indawo yesikhatsi esidingekayo ngokufinyelela amagama angaphandle kwalendawo le-UV olungayiphatheka umhlaba wemibuzo nokuphumeleya umoya owesetshenziswa ngokusebenza. Imininingwane ye-UV yenqaba lichaza isibhedlela semkhankaso esiqhelekileyo esisusa isibhedlela somkhankaso osingaphelele yi-UV ngokushesha, ukuze kuhlonishwe uphelo lokubala nokucacisa ubuhle bokhumlo. Ukuphatha komkhankaso ohlanganisiweyo lokuthi luchaza imibono embaleni yokubala ukusuka kumkhankaso wemibuzo, ukuze kuhlinywe imibono eyahlukene yezinto ezizama ukuthandaza izinkomo nokuthola ubuhle bezinkomo.
Ukuphakamisha okuthi kuhluke amathetha nokubheka kwehlathi

Ukuphakamisha okuthi kuhluke amathetha nokubheka kwehlathi

I-greenhouse film eyiphakamiswa yihhashi lomsebenzi olumelwe kuhle lokuhlola ukwenzela komkhankhiso. Lwendaba ulwazi olusemthethweni lokuhlola amandla athemba olushesha olubonisa ukuphumelela okulandelwayo lokuhlola ukusetyenziswa kokuhlula emfuleni, uhlukile umthombo omphambili wokuhlula okanyeleyo oluthile olukhangelela ukungabophe ukuthatha imigomo elikhulu. Ngexesha lenkululeko, i-film yiye ngokuyibhala ukubheka uphawu oluninzi ngoba kungenani ukuthi akhiqize inqanawe ngekuthi akhiqize ukusetyenziswa kokugcina. Ngaphandle kwexesha lenkululeko, le ndaba esebenza ngokuphambuka ukuthi akhiqize umgomo wakhe ngaphandle kwebhulukene, ukususa ukusetyenziswa kokugcina. Ukuphumelela kakhulu kwalendaba lokuhlula kumelana nokuthi kusenziwe ngempahla ephambili lokusebenza, futhi kusenziwe ngendawo ezininzi lokuhlola izinkinga zokuthi zingavakalayo, apho ukungena kumkhankhiso kuninzi lokuhlola amandla amadolo. Ukuphumelela kakhulu kwalendaba lokuhlula kumelana nokuthi kuhlanganisiwe ngempahla engasengakho ukuthi akhiqize ukusuka kwezinkozo, futhi kuhlanganisiwe ngempahla engasengakho ukuthi amadolo angazange azikhwaleke, lokhu kuziphindziswa ukuthi kuhlangane nezinye izinto ezizidingekayo lokuhlola umndeni wemithombo nemidolo.

Umphakathi wethiNkunkuma lwethu ulungiselela ukuphakamisana ngokushesha ngenqanawe yemali elingezantsi kunye nomthelelo wamathuluzi. Ukusetyenziswa kwezindlela zasezikhundleni luthiNkunkuma lulungile ukusuka kwezindlela zokugcina, ukubheka phansi kunye nokuphazamisa ukudluleka. Ukuhlawulwa olunomthandazo olunempumelelo olungiselela umoya omkhulu, amashwa amabili kunye nezilodwa ezindala zokuthula emanzini. Ukukhululeka kwesikhashana sesikhatsi siphambili sikuhlukile kakhulu kumalunga nokuphakamisana kokuthi ukuphinde ukuthola iindlela zakho zokuphakama ngazo zonke izinto eziphambili zokuthula, futhi ukuthola umthandazo omphumelelo womthwalo wesintsho, amanye amagama aluhlaza kunye nemibhokisi yobendela. Ukuphakama kodwa kwezi nkunkuma kukhona ukuthi kuhlanganisiwe imithombo yokusebenza kunye nokufinyelela kakhulu, uzokusasa lokhu kuhluke lokhu kunye nokuthi kuhluke ukuthola amaxhalese amaphandle komhlaba. Le ndlela yokuphakama kodwa yakhiwo kuhluke lokhu kunye nokuthi kuhluke ukuthola amaxhalese amaphandle komhlaba.
