Indlela yokuhlonza izimpawu zokugqumisa

Izimpawu zokukhombazidlala indima ebalulekile emadolobheni nasemigwaqweni emikhulu. Ziyithuluzi lokuphepha elibalulekile lokuqondisa izimoto nabahamba ngezinyawo ukushayela nokuhamba ngendlela efanele. Kodwa-ke, njengezindawo zomphakathi zangaphandle, izimpawu zokukhomba zidinga ukumelana novivinyo lwezimo zezulu ezinzima njengokushisa okuphezulu, izinga lokushisa eliphansi, ukukhanya okunamandla, kanye neziphepho ukuqinisekisa ukuqina kwazo isikhathi eside, ngakho-ke kudingeka kuthathwe izinyathelo ezidingekayo zokulwa nokugqwala. Yiziphi izinyathelo ezivamile zokulwa nokugqwala?

I-Qixiang aUmkhiqizi wezimpawu zokukhomba waseShayinaKusukela yasungulwa, ithathe ubuqotho njengomsebenzi wayo ongapheli. Ngokuphishekela kwayo ikhwalithi njalo kanye nokuqonda okujulile ngezitayela zemboni, ithole indawo eqinile emncintiswaneni omkhulu wemakethe futhi isibe ngumlingani othembekile wamakhasimende amaningi.

Ukuze kuvinjelwe ngempumelelo ukugqwala kwamabhodi ezimpawu, kubalulekile ukuqonda kuqala imbangela yokugqwala. Ngokuvamile, ukugqwala kwamabhodi ezibonakaliso kubangelwa kakhulu yizici zemvelo kanye nokuguga kwezinto ngokwazo, okuhlanganisa umswakama, imisebe ye-ultraviolet, i-oxidation, amakhemikhali, njll. Ngakho-ke, ukuze kuvinjelwe ukugqwala, lezi zici kumele zilawulwe.

Ukuphendula lezi zici zokugqwala, izindlela ezahlukahlukene zingasetshenziswa ukuvimbela ukugqwala kwamabhodi ezimpawu. Okokuqala, umswakama kanye nokugqwala kungagwenywa ngokuvikela ukugqokwa. Ukusebenzisa ungqimba lwesembozo esilwa nokugqwala ebusweni bebhodi lezibonakaliso kunganciphisa ngempumelelo inqubo yokugqwala futhi kuvimbele umswakama ekugqwaleni ubuso bensimbi. Ngaphezu kwalokho, ukusetshenziswa kwezinto ezinokumelana nokugqwala okuphezulu, njengensimbi engagqwali, kungathuthukisa kakhulu ukuqina kwamabhodi ezibonakaliso.

Okwesibili, ngezici zemvelo ezifana nemisebe ye-ultraviolet, ukuguga kwezimpawu zokuhlonza namalebula kungavinjelwa ngokuzimboza ngesendlalelo sezinto ezilwa nokuguga. Ngesikhathi esifanayo, lapho uklama izimpawu, kunconywa ukuthi ugweme ukusebenzisa izinto zensimbi ezifakwe i-oxid kalula futhi ucabangele ngokugcwele isakhiwo sazo kanye nokwakheka kwazo ukuze unciphise amathuba okugqwala.

Okokugcina, lapho kwenziwa izimpawu, ithonya lezici zabantu njengamakhemikhali lingagwenywa ngokukhetha izinto ezinokumelana nokugqwala okunamandla. Ngaphezu kwalokho, lapho kufakwa izimpawu, kubalulekile ukugwema ukusebenzisa amakhemikhali angase alimaze izimpawu, futhi unake ukunakekelwa njalo ngesikhathi sokusetshenziswa ukuze wandise isikhathi sazo sokusebenza.

Amathiphu

Ibanga lefilimu elibonakalisayo

Kunconywa ukuthi kunikezwe kuqala ifilimu ekhombisa idayimane (ibanga IV) noma ifilimu ekhombisa i-high-intensity (ibanga III). Ingqimba yayo yokumunca i-UV ingavimba imisebe ye-UV engaphezu kuka-95%, futhi ukusebenza kwayo kokulwa nokuguga kungcono kunokwemikhiqizo yezinga lobunjiniyela.

I-substrate yefilimu ekhanyayo idinga ukungezwa ngezithasiselo ezilwa ne-UV njenge-titanium dioxide (TiO₂) noma i-zinc oxide (ZnO), futhi okuqukethwe kwe-UV stabilizer kufanele kube ngu-≥1.5%.

Ukuhambisana kwe-substrate

Ipuleti lesisekelo se-aluminium alloy lidinga ukuncishiswa, ubukhulu befilimu ye-oxide bungu-≥10μm, futhi kuhlanganiswe nenqubo yokufafaza i-fluorocarbon (i-PVDF coating), ukubonakaliswa kwe-UV kukhushulwa ngo-15%-20%.

Ngamafuphi, ukuvimbela ukugqwala kuyinkinga engenakunganakwa ekukhiqizweni nasekusetshenzisweni kwezimpawu zokuhlonza. Ukuze kuqinisekiswe ukusebenza kahle nokuphepha kwamabhodi ezimpawu isikhathi eside, kudingeka kuthathwe izinyathelo zokuvimbela ukugqwala ezisebenzayo maqondana nomklamo, ukukhethwa kwezinto kanye nezinyathelo zokuzivikela. Uma udinga izimpawu zokuhlonza, sicelaXhumana nathi!
