Indlela yokuchonga iimpawu zokuqhola

Iimpawu zokuzazisaZidlala indima ebalulekileyo kwizixeko nakwiindlela ezinkulu. Zisisixhobo sokhuseleko esibalulekileyo sokukhokela izithuthi kunye nabahambi ngeenyawo ukuba baqhube kwaye bahambe ngokuchanekileyo. Nangona kunjalo, njengezakhiwo zikawonke-wonke zangaphandle, iimpawu zokuzazisa kufuneka zimelane novavanyo lweemeko zemozulu ezinzima ezifana nobushushu obuphezulu, ubushushu obuphantsi, ukukhanya okunamandla, kunye nezivuthuvuthu ukuqinisekisa ukuba zihlala ixesha elide, ngoko ke amanyathelo ayimfuneko okulwa nokugqwala kufuneka athathwe. Ngawaphi amanyathelo aqhelekileyo okulwa nokugqwala?

Qixiang yiUmenzi weempawu zokuchonga waseTshayinaUkususela oko yasekwa, ithathe ukuthembeka njengomsebenzi wayo ongagungqiyo. Ngokuqhubeka kwayo ifuna umgangatho kunye nokuqonda kakuhle iindlela zoshishino, ifumene indawo eqinileyo kukhuphiswano olukhulu lwemarike kwaye ibe liqabane elithembekileyo labathengi abaninzi.

Ukuze kuthintelwe ngempumelelo ukugqwala kweebhodi zeempawu, kubalulekile ukuqonda kuqala unobangela wokugqwala. Ngokubanzi, ukugqwala kweebhodi zezibonakaliso kubangelwa ikakhulu ziimeko zokusingqongileyo kunye nokuguga kwezinto ngokwazo, kubandakanya ukufuma, imitha ye-ultraviolet, i-oxidation, iikhemikhali, njl. Ke ngoko, ukuze kuthintelwe ukugqwala, ezi zinto kufuneka zilawulwe.

Ukuphendula kwezi zinto zokubola, iindlela ezahlukeneyo zingasetyenziswa ukuthintela ukubola kweebhodi zeempawu. Okokuqala, ukufuma kunye nokubola kunokuthintelwa ngokukhusela ukugquma. Ukusebenzisa umaleko wokugquma okuchasene nokugqwala kumphezulu webhodi yezibonakaliso kunokucothisa ngempumelelo inkqubo yokubola kwaye kuthintele ukufuma ekungcoleni umphezulu wesinyithi. Ukongeza, ukusetyenziswa kwezinto ezinokumelana nokugqwala okuphezulu, njengentsimbi engagqwaliyo, kunokuphucula kakhulu ukuqina kweebhodi zezibonakaliso.

Okwesibini, kwizinto zendalo ezifana nemitha ye-ultraviolet, ukuguga kweempawu zokuchonga kunye neelebheli kunokuthintelwa ngokuzigquma ngomaleko wezinto ezilwa nokuguga. Kwangaxeshanye, xa kusenziwa imiqondiso, kuyacetyiswa ukuba kuphetshwe ukusetyenziswa kwezinto zesinyithi ezicolisiswa lula kwaye kuqwalaselwe ngokupheleleyo ulwakhiwo lwazo kunye nolwakhiwo lwazo ukunciphisa amathuba okuba nokugqwala.

Okokugqibela, xa kusenziwa imiqondiso, impembelelo yezinto ezisetyenziswa ngabantu ezifana neekhemikhali inokuthintelwa ngokukhetha izinto ezinokumelana nokugqwala okunamandla. Ukongeza, xa kufakwa imiqondiso, kuyimfuneko ukuphepha ukusebenzisa iikhemikhali ezinokonakalisa imiqondiso, kwaye uqaphele ukugcinwa rhoqo kunye nokunyamekela ngexesha lokusetyenziswa ukuze wandise ubomi bazo benkonzo.

Iingcebiso

Ibanga lefilimu ebonakalisa ukukhanya

Kucetyiswa ukuba kubekwe phambili ifilimu ebonakalisa ukukhanya kwedayimani (ibanga lesi-IV) okanye ifilimu ebonakalisa ukukhanya okuphezulu (ibanga lesi-III). Umaleko wayo wokufunxa i-UV unokuthintela ngaphezulu kwe-95% yemitha ye-UV, kwaye ukusebenza kwayo okulwa nokwaluphala kungcono kunokweemveliso zobunjineli.

I-substrate yefilimu ekhanyayo kufuneka yongezwe nezinye izongezo ezichasene ne-UV ezifana ne-titanium dioxide (TiO₂) okanye i-zinc oxide (ZnO), kwaye umxholo we-UV stabilizer kufuneka ube yi-≥1.5%.

Ukuhambelana kwe-substrate

Ipleyiti yesiseko se-aluminium alloy kufuneka i-anodized, ubukhulu befilimu ye-oxide yi-≥10μm, kwaye xa idibene nenkqubo yokutshiza i-fluorocarbon (i-PVDF coating), ukubonakaliswa kwe-UV kunyuswa nge-15%-20%.

Ngamafutshane, ukuthintela ukugqwala yingxaki engenakuyekiswa ekuvelisweni nasekusetyenzisweni kweempawu zokuchonga. Ukuze kuqinisekiswe ukusebenza kakuhle kunye nokhuseleko lweebhodi zeempawu, kufuneka kuthathwe amanyathelo okuthintela ukugqwala asebenzayo ngokwendlela yoyilo, ukukhethwa kwezinto kunye namanyathelo okukhusela.
