Indima yeGlasi kwiiNkqubo zoDonga zamakhethini

Kuyilo lwamakhethini anamhlanje, iglasi yeyona nto iphambili yomda phakathi kwangaphakathi nangaphandle komkhusane. Ngamanye amazwi, iglasi inika ithuba lokubona into engaphandle, kwaye inika ukukhanya kwendalo, kunye nokwahlula kwizinto zemozulu. Ngaphandle koko, ikwasinika intuthuzelo yobushushu okanye imfihlo xa ifuneka. Ixesha elide, iglasi ngokungathandabuzekiyo yenye yezona zinto ziphambili zodonga lwamakhethini. Ithwala phantse yonke imiba ephambili ekuqhubeni kwayo: ukhuseleko, ubuhle, kunye ne-thermal. Kwizakhiwo zorhwebo zanamhlanje, inkqubo yodonga lwamakhethini e-aluminium isetyenziswa ngokubanzi njengendlela yokubonisa injongo yezakhiwo, ingcamango, okanye imeko yezoqoqosho. Ngobuhle, umgangatho wokwenziwa kweglasi unika isakhiwo fa?ade eyona nto iphambili. Nangona kunjalo, njengesithintelo, iglasi ayifanelekanga kuba ayihambelani neempawu zodonga lwekhethini eyilwe kakuhle. Cinga ukuba inexabiso eliphezulu le-thermal transmittance value (thelekisa nodonga oluqinileyo), i-brittle, ayiphefumli, kwaye ayikhuselekanga xa iphuka! Abavelisi beglasi kwiminyaka emashumi edlulileyo baye banikezela uluhlu olukhulu lwezisombululo zeglazing ezinokudibanisa ukusebenza kunye nobuhle ngendlela yokuba amathuba aphantse angenasiphelo kwiinkqubo ezahlukeneyo. Elinye igalelo elifanelekileyo leglasi ligalelo layo ekuzinzeni. Kwiimeko ezininzi, iglasi inokunceda ukunciphisa ukusetyenziswa kwamandla kunye nokuvelisa amandla ngokwayo. Kulwakhiwo olusebenzayo lwamakhethini, iindleko zodonga lwamakhethini ziqhutywa ikakhulu luhlobo lweglasi kunye nokusebenza kwayo okufunekayo. Iindidi zeGlasi zeNtsebenzo eNgcono Kwiminyaka yakutshanje, i-glazings esebenza ngamandla isetyenziswa ngokubanzi kwizakhiwo ukufezekisa iindleko ezizinzileyo zokusebenza. Kukho iintlobo ezintathu ezidumileyo zeeglasi zokusebenza eziphezulu: 1) Iglasi ye-E ephantsi ivumela ukukhanya ukuba kudlule ngelixa ugcina ubushushu kude. Ezi zikwanceda ekukhuseleni izinto zangaphakathi kwimitha ye-UV kunye ne-IR. Iglasi ye-E ephantsi inika intuthuzelo yobushushu ngokugcina umoya ofudumeleyo ngaphakathi ebusika kwaye ingavumeli umoya opholileyo ukuba uphume ehlotyeni. I-2) Iglasi yokulawula i-Solar yiglasi ekhethekileyo efakwe nge-oxide ehambisa ukushisa okuncinci kunye ne-glare ngaphakathi ngelixa ivumela ukukhanya kwelanga okwaneleyo. Ezi zikhusela ngaphakathi kwimitha ye-IR ngelixa zinciphisa imfuno yokukhanyisa okwenziweyo. I-3) Ulawulo lwe-solar ephantsi kwe-E yeglasi ibhloka i-radiation yelanga ngelixa ibonelela nge-insulation ye-thermal ephezulu ngaphandle kokufudumeza okanye ukupholisa. Iglasi ye-E ephantsi ithande ukutshisa kakhulu phantsi kwemitha yelanga ethe ngqo, kanye apho ulawulo lwelanga ephantsi-E yeglasi lunceda khona. Ezi ziqhele ukusetyenziswa kwiindonga zeglasi zekhethini ukunciphisa iindleko zokupholisa umoya kwizakhiwo, okukhokelela ekusebenzeni kakuhle kwamandla.
