Kuyini ukumelana nokugqwala kwamakhoyili ensimbi apendwe ngaphambili we-ppgl?

Uma kukhulunywa ngokuqina nobuhle ekwakhiweni nasekukhiqizeni, insimbi ependwe ngaphambilini iyisinqumo esiphezulu. Phakathi kwabahlinzeki abahamba phambili embonini, abahlinzeki bensimbi abapendwe ngaphambilini baseChina banedumela eliqinile lokuletha imikhiqizo esezingeni eliphezulu, okuhlanganisa ikhoyili yensimbi eyenziwe ngopende waseChina kanyeAmakhoyili e-PPGL. Kodwa umbuzo uvame ukuvela: Kuyini ukumelana nokugqwala kwekhoyili yensimbi enombala?
Ikhoyili yensimbi efakwe umbala, eyaziwa nangokuthi insimbi ependwe ngaphambilini, iklanyelwe ukumelana nezakhi kuyilapho igcina ukubukeka kwayo okunempilo. Ukumelana nokugqwala kwala makhoyili kubangelwa ikakhulukazi ungqimba oluvikelayo olusetshenziswa ngesikhathi sokukhiqiza. Isisekelo sensimbi simbozwe ungqimba lwezinc noma i-aluminium, kulandelwa i-primer ne-topcoat. Le ndlela enezingqimba eziningi ayigcini nje ngokuthuthukisa ubuhle, kodwa futhi inikeza umgoqo oqinile ngokumelene nomswakama, amakhemikhali kanye nemisebe ye-UV.
Izinga le-coating lidlala indima ebalulekile ekunqumeni ukumelana nokugqwala. Abahlinzeki bensimbi abapendwe kusengaphambili abahamba phambili baseChina baqinisekisa ukuthi imikhiqizo yabo ihlangabezana nezindinganiso eziqinile zemboni, ihlinzeka ngezingubo ezimelana nokugqwala nokuwohloka iminyaka eminingi. Isibonelo, Ikhoyili ye-PPGL (insimbi ependwe kusengaphambili ye-galvalume) yaziwa kakhulu ngokumelana nokugqwala, okuyenza ilungele izindawo ezinokhahlo.

Ukutshala imali ekhoyili yensimbi enombala wekhwalithi ephezulu evela kumnikezeli othembekile ngeke nje kuqinisekise ukuphila isikhathi eside kodwa futhi kuzonciphisa izindleko zokuyilungisa ngokuhamba kwesikhathi. Kungakhathaliseki ukuthi usezokwakha, ukukhiqiza noma yimuphi umkhakha odinga izinto ezihlala isikhathi eside, ukukhetha insimbi efanele ependwe ngaphambilini kungenza umehluko.
Kafushane, lapho ucubungulaabahlinzeki bensimbi abapendwe ngaphambilini, ikakhulukazi labo abavela e-China, babheka imikhiqizo enokumelana nokugqwala okuphakeme. Ngokukhetha okulungile, ungajabulela izinzuzo zokuqina nobuhle, uqinisekisa ukuthi iphrojekthi yakho izomelana nesikhathi.
