Uzigqumisa kanjani izimpawu zokuhlonza

Izimpawu zokuhlonzadlala indima ebalulekile emadolobheni nasemigwaqweni emikhulu. Ziyithuluzi lokuphepha elibalulekile lokuqondisa izimoto nabahamba ngezinyawo ukushayela nokuhamba ngendlela efanele. Kodwa-ke, njengezindawo zomphakathi ezingaphandle, izimpawu zokuhlonza zidinga ukumelana nokuhlolwa kwezimo zezulu ezinzima njengezinga lokushisa eliphezulu, izinga lokushisa eliphansi, ukukhanya okunamandla, neziphepho ukuze kuqinisekiswe ukuqina kwazo kwesikhathi eside, ngakho-ke kudingeka kuthathwe izinyathelo ezidingekayo zokulwa nokugqwala. Yiziphi izinyathelo ezijwayelekile zokunqanda ukugqwala?

Qixiang aUmkhiqizi wezimpawu zokuhlonza waseShayina. Selokhu yasungulwa, ithathe ubuqotho njengomsebenzi wayo ongaguquki. Ngokuphikelela kwayo kokuphishekela ikhwalithi kanye nokuqondisisa okujulile kokuthambekela komkhakha, isithole isisekelo esiqinile emqhudelwaneni oshubile wezimakethe futhi isibe uzakwethu othembekile wamakhasimende amaningi.

Ukuze ugweme ngempumelelo ukugqwala kwamabhodi ezimpawu, kubalulekile ukuqonda kuqala imbangela yokugqwala. Ngokuvamile, ukugqwala kwamabhodi ezimpawu kubangelwa ikakhulukazi izici zemvelo kanye nokuguga kwento ngokwayo, okuhlanganisa umswakama, imisebe ye-ultraviolet, i-oxidation, amakhemikhali, njll. Ngakho-ke, ukuze kuvinjwe ukugqwala, lezi zici kufanele zilawulwe.

Ukusabela kulezi zici zokugqwala, izindlela ezihlukahlukene zingasetshenziswa ukuvimbela ukugqwala kwamabhodi ophawu. Okokuqala, umswakama kanye ne-oxidation kungagwenywa ngokuvikela ukunamathela. Ukusebenzisa ungqimba oluvikela ukugqwala endaweni engaphezulu yebhodi lezimpawu kunganciphisa ngempumelelo inqubo ye-oxidation futhi kuvimbele umswakama ukuthi ungagqwali indawo yensimbi. Ngaphezu kwalokho, ukusetshenziswa kwezinto ezinokumelana nokugqwala okuphezulu, njengensimbi engagqwali, kungathuthukisa kakhulu ukuqina kwamabhodi ophawu.

Okwesibili, ezicini zemvelo ezifana nemisebe ye-ultraviolet, ukuguga kwezimpawu zokuhlonza namalebula kungavinjelwa ngokuwamboza ngongqimba lwezinto ezilwa nokuguga. Ngesikhathi esifanayo, lapho uklama izimpawu, kunconywa ukuba ugweme ukusetshenziswa kwezinto zensimbi ezine-oxidized kalula futhi ucabangele ngokugcwele isakhiwo sabo kanye nokuhlelwa ukuze kuncishiswe amathuba okugqwala.

Okokugcina, lapho kwenziwa izimpawu, ithonya lezici zomuntu ezifana namakhemikhali lingagwenywa ngokukhetha izinto ezinokumelana nokugqwala okuqinile. Ngaphezu kwalokho, lapho ufaka izimpawu, kuyadingeka ukugwema ukusetshenziswa kwamakhemikhali angalimaza izimpawu, futhi unake ukugcinwa nokunakekelwa okuvamile ngesikhathi sokusetshenziswa ukwandisa impilo yabo yesevisi.

Ibanga lefilimu elikhombisayo

Kunconywa ukubeka kuqala ibanga ledayimane (ibanga lesi-IV) noma ifilimu ebonisa amandla aphezulu (ibanga lesi-III). Isendlalelo sayo sokumunca i-UV singavimba ngaphezu kuka-95% wemisebe ye-UV, futhi ukusebenza kwayo kokulwa nokuguga kungcono kunokwemikhiqizo yezinga lobunjiniyela.

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

Ukuhambisana kwe-substrate

I-aluminium alloy base plate idinga ukugcotshwa, ukujiya kwefilimu ye-oxide kungu-≥10μm, futhi kuhlanganiswe nenqubo yokufafaza nge-fluorocarbon (i-PVDF), ukukhanya kwe-UV kukhuphuka ngo-15% -20%.

Ngamafuphi, ukuvimbela ukugqwala yinkinga engeke ishaywe indiva ekukhiqizweni nasekusetshenzisweni kwezimpawu zokuhlonza. Ukuze kuqinisekiswe ukusebenza kahle kwesikhathi eside nokuphepha kwamabhodi ezimpawu, izinyathelo ezisebenzayo zokuvimbela ukugqwala kufanele zithathwe mayelana nomklamo, ukukhethwa kwempahla kanye nezinyathelo zokuzivikela. Ngicela, uma udinga izimpawu zomazisiXhumana nathi!
