Izindlela ezincane zokugcina njengekusetshenziswa kwamaphutha amancane yokugcina futhi ukudibanisa izikhala ezinye ezingaphakathi kwezinsuku ezingabi ngekhaya kuyasebenza kahle ekunikezeni umkhawulo wokuthwasa kwezikhola.

Ukuqonda nokusula Izinkinga Zokufihla Kwesikhumba Semthwakathi Sasepolycarbonate

Ukuqonda kahle izinto ezingafihli kusikhumba semthwakathi sasepolycarbonate kubalulekile kakhulu ukuthi isikhumba sisebenza njani ngemva kwezinsuku. Uma abasebenzi bahlukanisa izinkinga njengezinkampani zemvula emnyama, isilikon esingapheli, noma izibhakabhaka zezinhlanzi, bavuselela amachina ayalwa. Lezi zimiselo zinokuthintela izihlalo zokulinda UV ezihlukile kusikhumba. Umlando waseplastik wasegreenhouse wabeka izinombolo ezithembekile kugogo laseyala. Amabhizo akhe asekhaya abonisa ukuthi ngamashumi ayisithupha kwezishumi ezine zokubuyisela kusikhumba kwenza kahle ngokusebenzisa izindlela zokuchitha ezingavumelekile ngokuhlukanisa izinkinga.

Ukuhlukanisa Izinkampani Zemvula Emnyama, Isilikon Esingapheli, Nokufihla Kwezinhlanzi

Izinkampani ezintathu eziphambili zidinga izindlela zokusula ezingahlukena:

Izinkampani	Amadokumenti Okuhlanganisa	Isivumelwano Sokufihla	Isilonga Sokusula Esisho
Izinkampani Zemvula Emnyama	Kubonakala njengezincwadi, nokubonakala kahle kwezinhlobo zokufihla	Iyadlula emazibini amancane	Isilutshane sesivinega (5% yomthubi wemvinyo)
Ukubuyiselwa kwe-Silicone	Amaphakathi amandla endawo yokugxilwa kwezihlangothi	Iyakhuluma nesifunda/izinkampani zokususa	Isipropili alkholi (ukuphakanyiswa kwe-70%)
Ukubhisha kwemithi	Isibhisho sesihlanu/sembili esinamaphepho amahle amahle	Iyakhuluma ngokuvamile kwe-alkali	Ihydrogen peroxide (isilutshane se-3%)

Amaphakathi wezindiza eziningi (ukuphakama kwezindiza) kubhekana ngamapatterni emikhawuli ngokuvalelwa kwemithombo; izilikonu ezingasolwanga zibhala amathela amashini emhlabathi ngezikhawuli zomkhosi; ukuthi kubheka okunye kubhekana ngamathela amashini. Kumaqondiso akhiywe ngokuphakeme, izilayishe zokucima ezihlanganiswe ngabasebenzi beshisayo besifundazwe sokuzimela ziyabulawa ukubona kokugcina ngaphandle kokuvimbela imithombo yokuqinisa—kubalulekile kakhulu emazweni aphakathi kwesiphelo sokuzimela.

Ukuphatha Izinkothamo Zesifundazwe Sokuzimela Ngokusebenza Kwemithombo Yokuqinisa

Ukuphatha ukuthi kubhekele umkhosi kufuna izisombululo esizihlanganisa kwezinkothamo nezimithombo. Ukuguqula kwesilinganiso sekhanda kuyabhekana ngokuguqula kwezinkothamo nezimithombo—ikhoefishenti yekhanda yezinkothamo yezincane iyafika ku-68 Å—kuyavimbela izilayishe zezinkothamo. Kunezisombululo eziningi zokuphatha okuzosinda lokhu ngokuphakeme.

Ukuthi Kuyaphakama Kwesilayishe Sasezinyoni Ngokuguqula Kwesilinganiso Sekhanda: Iziphakade Zomlando

Ithepu yemisipha—eyenziwe ngokusebenzisa isilika sesi-akrilek sokuphakama kwezintemperatura—iyabonisa ubukhulu bekho ekubeni kubaluleke kuzo iziphulo zemithambo. Ngaphandle kokuthi ithepu yezindaba, iyakhangelwa ukuthi iphakamise amandla okugqibela kuzo zonke iziphulo zemithambo ephakeme:

• Ukusebenza Kwesihlanu : Amandla okugqibela akhangelwa kusukela ku-94% emva kwezinsuku e-60 eziphakamile kwi-40°C (104°F) ngekuthi kubhekwa ngomoya wokuqala
• Ubukhulu Bekhona Kwezinkanyezi : Akukho phakade lokugqibela emva kwezinsuku eziyishumi nezintathu kwi-25°C (13°F) emva kwezinsuku zokufuna nokuvula okuphindeleka

Iziphulo zokugqibela zizwela ngokuphakama kwe-81% lapho zihlanganiswa ngaphezulu kwamajonti okuchazwa ngokuphelele, njengoba kubonakalise kwezinsuku zokuzilungisa kwe-2023. Ukuchazwa kwesifunda kuyisidingo esibalulekile—umoya osethu noma umnyama owenziwe ngumfundo uya kunciphisa ubukhulu ngokuphakama kwe-40%. Ukuze ubone ukuthi kunezindlela ezinamandla, hlukanisa ukuchaza kwezithempu nesikhathi sokuzilungisa kwesifunda.

Isikhombisi Sokuqala

Yini okubangela ukuthi kubekwe amasimbi noma amasitha kwezincwadi zepolikarbonethe?

Amasimbi noma amasitha kwezincwadi zepolikarbonethe kubangela ngokuphakama kwezincwadi zemfula enkulu, ubukhulu bekwezinkanyezi, namasiphiyana okuhlanganisa amasiphiyana amaningi njengezincwadi zemfula noma umnyama owenziwe ngumfundo owenziwe ngokuphakama kwezincwadi.

Uyakwenza kanjani ukuthi uzilungele izicelo zokuphatha kwe-UV noma izicelo zokuvula ngokuphakama kwezincwadi?

Sebenzisa izikhakha zesilika esizimisele kwe-pH nezincwadi zemithi yezinkukhu ezingenayo ukuthi zihlabe, zingavunyelwe izikhakha zesilika esizimisele kwe-pH, futhi amashini okuhlanza ngokuphepha okungafana nokuphepha kwe-500 PSI ukuze uvikwe kwezinkinga futhi uhlale ukubeka imithombo yokuqinisa kwe-UV nezithembiso zokuhlaba.

Yini indlela eyamukele kangako yokubonisa nokususa izinto ezahlukene eziphathelene nesibhakabhaka sesigodlo?
