1.Ukwaziswa ngokubanzi kwePPGL
I-PPGL, imele intsimbi ye-galvalume epeyintwe kwangaphambili, ikwabizwa ngokuba yintsimbi yentsimbi epeyintwe ngaphambili, ene sheet yentsimbi yegalvalume njenge substrate.
I-PPGL okanye i-coil yensimbi ye-galvalume epeyintwe ngaphambili, ifakwe ngomxube we-aluminium, i-zinc, kunye nezinye izinto zokulandelela.Ukubunjwa okuqhelekileyo kwengubo ye-galvalume yi-55% ye-aluminium, i-43.4% ye-zinc, kunye ne-1.6% yokulandelela izinto.
Amashidi e-PPGL alungiselelwe ngokudibanisa amandla entsimbi kunye nobuchule bokuchasana ne-corrosive yentsimbi yentsimbi efana neZinc okanye iAluminium.Iyakwazi ukumelana nemozulu kunye nokuthotywa kwemekobume kwaye inokubethwa, icinezelwe, iqulunqwe, okanye idityaniswe ngayo nayiphi na indlela enokwenzeka ngokwemfuno.Zenziwe kwiinkcukacha ezahlukeneyo ukuze zihambelane nezicelo ezahlukeneyo.Zikhaphukhaphu kwaye zomelele ukuze zibekwe lula kunye nokubonelela ngokuqina okuphezulu.Aziqhekeki phantsi koxinzelelo kwaye zenziwe kumgangatho ophezulu.
2.Iinzuzo eziphambili zemveliso
•Aukuxhathisa kwemvula ye-cid:
Indlela yokukhusela i-coating: kulula ukwenza imvula ye-asidi kwindawo yokukhutshwa kwamashishini aphezulu okanye ukungcola.Ukungena kwe-Acid kuya kubumba phezu kwentsimbi efakwe ngaphambili kunye nokukhawuleza ukubola, ukwenza i-blistering, i-peeling kunye nezinye izinto.
• Ukumelana ne-UV:
Indlela yokukhusela i-coating: phantsi kwemeko ye-ultraviolet okanye ilanga elinamandla, ipleyiti edibeneyo iya kuba ngumgubo kunye ne-denatured, eya kubonisa i-discoloration kunye nokulahlekelwa kwe-luster, kwaye ngokukhawuleza ilahlekelwe yingubo.
•Mubushushu kunye nokumelana nobushushu:
Indlela yokukhusela i-coating: kwindawo eshushu kunye nefumileyo, uxinzelelo oluphezulu lwe-osmotic lomphunga wamanzi luya kukhawulezisa ukungena, lenze i-denaturation yefilimu yokugubungela, kwaye emva koko i-corrode i-substrate, kwaye i-bubble kunye ne-peeling iya kwenzeka.
•Lukumelana nobushushu:
Indlela yokukhusela i-coating: ininzi yengubo inokugcina ukusebenza okuzinzileyo kokusebenza ngaphezu kwe-0 ° C. Nangona kunjalo, xa iqondo lokushisa lingaphantsi kwe-20-40 ° C kwindawo ebandayo, iingubo eziqhelekileyo ziya kuba yi-brittle, zigobe okanye ziwe, ngoko. umphumo wokukhusela ulahlekile ngokupheleleyo.
•Aisicelo
Umbala ogqunywe ngesinyithi / intsimbi ye-zinc aluminized isetyenziselwa ukwakhiwa kophahla, umaleko womphezulu webalcony, isakhelo sefestile, isikrini kunye nezixhobo zombane.Intsimbi epeyintiweyo inokubunjwa phantse kuyo nayiphi na imilo, kwaye inokumelana nemozulu ebalaseleyo, ubomi obugqwesileyo kunye nokukhethwa kokuthungwa.
