Indlela yokuqhola iimpawu zokuzazisa

Iimpawu zokuchongazidlala indima ebalulekileyo ezixekweni nakuhola wendlela. Zisisixhobo sokhuseleko esiyimfuneko sokukhokela izithuthi nabahambi ngeenyawo ukuqhuba nokuhamba ngokuchanekileyo. Nangona kunjalo, njengezixhobo zoluntu zangaphandle, iimpawu zokuchongwa kufuneka zimelane novavanyo lweemeko zemozulu ezinzima ezifana nobushushu obuphezulu, ubushushu obuphantsi, ukukhanya okuqinileyo, kunye nezaqhwithi zokuqinisekisa ukuqina kwazo kwexesha elide, ngoko ke kufuneka kuthathwe amanyathelo okulwa nomhlwa. Ngawaphi amanyathelo aqhelekileyo okuthintela ukubola?

Qixiang yiUmenzi weempawu zesazisi waseTshayina. Ukusukela ekusekweni kwayo, ithathe ingqibelelo njengomsebenzi wayo ongagungqiyo. Ngokuzingisa ekusukeleni umgangatho kunye nokuqonda okubukhali kwiintsingiselo zeshishini, ifumene unyawo oluqinileyo kukhuphiswano oluqatha lwemarike kwaye ibe liqabane elithembekileyo labathengi abaninzi.

Ukuze uthintele ngokufanelekileyo ukubola kweebhodi zeempawu, kuyimfuneko ukuqonda kuqala unobangela wokubola. Ngokuqhelekileyo, ukubola kweebhodi zemiqondiso kubangelwa ubukhulu becala yimiba yokusingqongileyo kunye nokuguga kwezinto ngokwazo, kuquka ukufuma, imitha ye-ultraviolet, i-oxidation, iikhemikhali, njl. Ngoko ke, ukuze kuthintelwe ukubola, le miba kufuneka ilawulwe.

Ukuphendula le miba ye-corrosion, iindlela ezahlukeneyo zingasetyenziswa ukunqanda ukubola kweebhodi zemiqondiso. Okokuqala, ukufuma kunye ne-oxidation kunokuphetshwa ngokukhuselwa kwengubo. Ukusebenzisa umaleko we-anti-rust coating kumphezulu webhodi yophawu kunokucothisa ngokufanelekileyo inkqubo ye-oxidation kwaye kuthintele ukufuma ekungcoleni umphezulu wesinyithi. Ukongeza, ukusetyenziswa kwezinto ezinokumelana nokugqwala okuphezulu, njengensimbi engenasici, kunokuphucula kakhulu ukuqina kweebhodi zeempawu.

Okwesibini, kwizinto zendalo ezifana nemisebe ye-ultraviolet, ukuguga kweempawu zokuchongwa kunye neelebhile kunokuthintelwa ngokuzigubungela ngoluhlu lwezinto ezichasayo. Kwangaxeshanye, xa uyila iimpawu, kucetyiswa ukuba ugweme ukusetyenziswa kwezixhobo zetsimbi ezixutywe lula kwaye unike ingqwalaselo epheleleyo kubume bazo kunye nokubekwa kwazo ukuze kuncitshiswe ukubola.

Okokugqibela, xa kusenziwa imiqondiso, impembelelo yezinto zabantu ezinje ngekhemikhali inokuphetshwa ngokukhetha izinto ezinokumelana nomhlwa. Ukongezelela, xa ufaka iimpawu, kuyimfuneko ukuphepha ukusetyenziswa kweekhemikhali ezinokulimaza iimpawu, kwaye ubeke ingqalelo ekugcinweni rhoqo kunye nokunyamekela ngexesha lokusetyenziswa ukwandisa ubomi babo benkonzo.

Iingcebiso

Ibakala lefilimu ezibonakalisayo

Kucetyiswa ukuba unike kuqala ibakala ledayimani (ibakala IV) okanye ifilimu ebonakalisa amandla aphezulu (ibakala le-III). Umaleko wayo wokufunxa we-UV unokuthintela ngaphezulu kwe-95% yemitha ye-UV, kwaye ukusebenza kwayo kokuchasana nokuguga kubhetele kuneemveliso zodidi lobunjineli.

I-substrate yefilimu ebonakalisayo kufuneka yongezwe kunye ne-anti-UV additives ezifana ne-titanium dioxide (TiO₂) okanye i-zinc oxide (ZnO), kunye nomxholo we-UV stabilizer kufuneka ube ≥1.5%.

Ukuhambelana kwe-substrate

Isiseko se-aluminiyam i-alloy plate kufuneka i-anodized, ubukhulu befilimu ye-oxide yi-≥10μm, kwaye idibaniswe nenkqubo yokutshiza i-fluorocarbon (i-PVDF yokugqoka), ukubonakaliswa kwe-UV kwanda nge-15% -20%.

Ngamafutshane, ukuthintela umhlwa ngumba ongenakho ukuhoywa kwimveliso kunye nokusetyenziswa kweempawu zokuchonga. Ukuze kuqinisekiswe ukusebenza kwexesha elide kunye nokukhuseleka kweebhodi zeempawu, amanyathelo asebenzayo okuthintela i-corrosion kufuneka athathwe ngokumalunga noyilo, ukukhethwa kwezinto eziphathekayo kunye namanyathelo okukhusela.
