Kutheni le nto i-ETFE ihlala isetyenziselwa ukwakha iiNdawo zokuHlala?

I-Aarhus Botanical Garden eDenmark isebenzisa i-ETFE emoyeni umqamelo inwebu isakhiwo ukwakha greenhouse, nto leyo Denmark kaThixo isimboli greenhouse. Ubume bendlu yokukhulisela ubushushu buphuculwa ngokubala okuphambili ukuze kufumaneke eyona angle yokukhanya kwelanga ebusika kwaye ngokuphendululekileyo ehlotyeni. Iintlobo ngeentlobo zezityalo zetropikhi, imithi kunye neentyatyambo zigcwalisa i-oval greenhouse ngedome ebonakalayo.

I-Eden Greenhouse yase-UK yakhiwe kwi-2001 kwaye yayiyisakhiwo esikhulu se-ETFE isakhiwo se-membrane esakhiwe ngokusebenzisa izinto ze-ETFE kwihlabathi ngelo xesha. Ukuqokelela phantse zonke izityalo ezisehlabathini, ngaphezu kwe-4,500 iintlobo kunye ne-134,000 yeentyatyambo kunye nemithi, i-greenhouse iqulethwe ngezakhiwo ezine ezidibeneyo ezine-dome, ezigutyungelwe nge-membrane yesakhiwo esicacileyo esenziwe nge-ETFE.

Njengoko iimbono zokukhuselwa kwendalo kunye nophuhliso oluzinzileyo ziqhubeka zimiliselwe ngokunzulu ezintliziyweni zabantu, ingqwalasela engakumbi ihlawulwa ekukhuselweni kwezityalo ezinqabileyo. Ukuvela kwe-ETFE i-membrane ye-botanical gardens ikhusele kakuhle ukusinda kwezityalo ezinqabileyo.

Ngokubhekiselele kwi-greenhouses yezolimo, iifilimu ze-ETFE zibonelela ngendawo yokuhlala kwindawo yokutyala kwezolimo. Ngenxa yokuba ine-full-band optical fiber permeability, iluncedo ngakumbi kwizityalo ekufunxeni nge-infrared, isusa imitha ephantsi ebusuku, kwaye ikhuthaza ukukhula kwesityalo. EJapan, phantse zonke izindlu zokugcina izityalo ziyayisebenzisa.

Kutheni i-ETFE ihlala isetyenziselwa ukwakha izindlu zokugcina izityalo?

Ikakhulu ngenxa yokuhambisa ukukhanya kwayo okulungileyo. Ukuhanjiswa kokukhanya kwefilimu ye-ETFE kunokufikelela ngaphezu kwe-94%, eqaqambileyo ngaphakathi ngaphakathi nje ngaphandle, ukubonelela ngeemeko ezilungileyo zokukhanyisa izityalo. Ukukhanya okugcweleyo kwendalo kubalulekile kwimpilo yezityalo, ngaloo ndlela kugcina izityalo zikhuselekile kwaye zisempilweni, ukwandisa isivuno kunye nomgangatho wemifuno kunye neziqhamo, kunye nokunciphisa ukusetyenziswa kwamanzi, ukunciphisa iindleko kunye nokuphucula ukusebenza kakuhle.

Plus inobomi benkonzo obude kakhulu. Ukuxhatshazwa kwexesha elide lemozulu yezinto ze-ETFE (i-25-30 iminyaka) kusindisa iindleko zezinto eziphathekayo kunye nokunciphisa iindleko zabasebenzi ngenxa yokuba ukuphinda kusetyenziswe kwakhona akufuneki, ukwandisa kakhulu isivuno se-horticultural greenhouses ngokulungisa indawo yangaphakathi.

Ulimo sisiseko selizwe kunye nesiseko sokuphila kwabantu. Njengenxalenye ebalulekileyo yezolimo zanamhlanje, ii-greenhouses zinokukhusela ngokufanelekileyo izityalo ngaphakathi ngelixa zibonelela ngokukhanya kwelanga kunye nobushushu obufunekayo ekukhuleni. Izinto ze-ETFE zineenzuzo ezingenakuthelekiswa nezinye izinto.
