Galvalume Coil e sere ese nke ọma, nke a na-akpọkwa Ppgl Coil ma ọ bụ Ppgl Steel Coil, bụ ihe dị mkpa maka iwu mgbidi ákwà mgbochi, ebe a na-etinye ngwa, na njem oyi. Mgbochi nchara ya na-emetụta ndụ ọrụ nke ngwaahịa ahụ, ọnụ ahịa mmezi, na nchekwa ya. N'ebe siri ike dịka mpaghara mmiri na mpaghara mmetọ ụlọ ọrụ mmepụta ihe, ịchọta ụzọ isi mee ka iguzogide nchara nke Ppgl Steel dịkwuo elu bụ nnukwu nchegbu na ụlọ ọrụ ahụ. Isiokwu a na-enye atụmatụ ise bara uru dabere na ojiji ụwa n'ezie.
I. Mee ka ihe ndị dị n'ime ala dịkwuo mma: Mmalite dị mma maka iguzogide nrụrụ aka
Nguzogide nchara nke Ppgl Steel dabere na ihe mejupụtara ya, ihe mkpuchi zinc aluminized (Galvalume Coil).
1. Jikwaa Mkpuchi ahụ: Ezigbo Ppgl Steel Coil chọrọ ngwakọta kwesịrị ekwesị nke aluminom (55%), zinc (43.4%), na silicon (1.6%). Silicon na-enyere aka ịmepụta oyi akwa alloy ma gbochie oyi akwa zinc ka ọ ghara ịpụta. Mkpuchi zinc aluminized kwesịrị ịdị opekata mpe 120 g/m² (akụkụ abụọ). N'ebe dị n'ụsọ oké osimiri nke na-emebi emebi nke ukwuu, ọ nwere ike ịbụ ihe karịrị 150 g/m² iji mepụta oyi akwa nchebe siri ike.
2. Họrọ Ala Dị Ọcha: Ala Ppgl Steel kwesịrị inwe obere ihe ruru unyi dịka carbon na sọlfọ. Nke a na-ebelata obere ntụpọ ma na-egbochi ire ere ịmalite. Ọ ka mma iji ala zinc aluminized nke dabara na ọkọlọtọ ASTM A792 iji belata ihe egwu nke ire ere.
II. Mee ka elu ahụ dị mma nke ọma: Meziwanye mmịnye mkpuchi ahụ
Nrapado nke Galvalume Steel Coil e sere ese na-emetụta ike ya iguzogide nchara. Ọgwụgwọ tupu elu dị oke mkpa:
1. Hichaa n'ime usoro atọ: A ga-asa ihe mkpuchi ahụ site na ịsacha alkaline iji wepụ mmanụ, ịsacha acid iji wepụ nchara, na ịsacha ya iji mee ka ọ ghara ịdị ọcha. Nke a na-eme ka elu ahụ dị ọcha ma kwụsị "njehie n'etiti ihe mkpuchi ahụ na ihe mkpuchi ahụ."
2. Mmelite Passivation: Jiri chromate passivation ma ọ bụ chromium – free passivation (nke ka mma maka gburugburu ebe obibi). Nke a na-emepụta ihe nkiri passivation otu otu na Galvalume Steel Coil substrate. Ọ na-enyere mkpuchi ahụ aka ịrapara nke ọma ma gbochie ihe ndị na-emebi emebi.
3. Kpọọ nke ọma: Mgbe a gwọchara ya tupu oge eruo, kpoo ihe mkpuchi ahụ ngwa ngwa. Debe mmiri dị n'elu ya n'okpuru 0.1% iji gbochie ire ere.

III. Họrọ mkpuchi kwesịrị ekwesị: Wuo nchekwa ọtụtụ oyi akwa
Mkpuchi ahụ bụ ihe nchebe kachasị maka Coil Ppgl. Mgbe ị na-ahọrọ usoro mkpuchi, chee echiche banyere iguzogide ihu igwe, iguzogide kemịkalụ, na njikọta:
1. Họrọ ihe mkpuchi: Ihe mkpuchi Epoxy dị mma n'ihi na ha na-arapara nke ọma ma na-egbochi ihe ndị na-emebi emebi. Maka ọnọdụ dị oke mkpa, jiri ihe mkpuchi polyurethane mee ka mkpuchi ahụ dịkwuo mfe ma ghara iguzogide mmiri nnu.
2. Họrọ Topcoat: Họrọ mkpuchi na-eguzogide ihu igwe.
– Maka gburugburu ebe obibi nkịtị: Uwe elu polyester na-eguzogide ihu igwe dị elu bụ ezigbo nhọrọ. Ha na-eguzogide UV na ịka nká nke ọma, ha adịghịkwa oke ọnụ.
– Maka gburugburu ebe siri ike (dịka ebe mmiri ma ọ bụ ebe mmepụta ihe): PVDF (polyvinylidene fluoride) kacha mma. Ha na-eguzogide ihu igwe na kemịkalụ nke ukwuu ma nwee ike ịdịru ihe karịrị afọ 20.
3. Jikwaa ọkpụrụkpụ mkpuchi ahụ: Ihe mkpuchi ahụ kwesịrị ịdị ọkpụrụkpụ 5 – 7μm, ihe mkpuchi ahụ kwesịrị ịdị 15 – 20μm. Oke ọkpụrụkpụ mkpuchi ahụ kwesịrị ịdị opekata mpe 25μm iji zere nsogbu dịka oghere ntụtụ.
IV. Soro Mmepụta na Ntinye Dị Mma: Zere ire ere site na mmejọ
Ọbụnadị Galvalume Coil e sere agba dị elu nwere ike ịkwụsị iguzogide nchara ma ọ bụrụ na ahazi ya nke ọma:
1. Jikwaa Usoro Mkpuchi: Jiri mkpuchi roller mee ka mkpuchi ahụ dị larịị. Debe okpomọkụ nke na-agwọ ya na 230 – 250℃ maka sekọnd 30 – 60. Nke a na-egbochi mkpuchi ahụ ịgbawa agbawa nke ukwuu.
2. Chebe n'oge ntinye:
– Akọchala elu PPGL Coil. Jiri agba ndozi pụrụ iche dozie ihe ndị ahụ ozugbo.
– Hapụ njikọ mgbasa mgbe ị na-etinye ya iji gbochie mkpuchi ahụ ịgbawa n'ihi mgbanwe okpomọkụ.
– N'ebe dị n'ụsọ oké osimiri ma ọ bụ ebe mmiri dị, jiri ihe njide ígwè anaghị agba nchara iji zere ire ere site na ọla dị iche iche metụrụ aka.
V. Na-edobe Ya Mgbe Niile: Mee Ka Kọndọlụ ahụ Dịte Aka
Ndozi mgbe niile nwere ike ibelata nchara, ọkachasị maka Galvalume Steel Coil n'èzí:
1. Na-ehicha mgbe niile: Jiri mmiri ma ọ bụ ihe nhicha na-anaghị acha ọcha hichaa eriri igwe ahụ ma ọ dịkarịa ala ugboro 1-2 n'afọ. Nke a na-ewepụ uzuzu, nnu, na unyi ndị ọzọ nwere ike ibute ire ere.
2. Dozie Mmebi Ngwa Ngwa: Ọ bụrụ na e nwere ihe ọ bụla na-agbawa ma ọ bụ mebie ihe mkpuchi ahụ, jiri agba ndozi dabara adaba ozugbo iji gbochie ihe ndị na-emebi emebi iru ihe ahụ.
3. Kewapụ onwe gị n'ebe gbara gburugburu ebe obibi dị: Maka eriri ndị dị nso na isi iyi acid ma ọ bụ alkali ma ọ bụ n'akụkụ oké osimiri, jiri ihe mgbochi nchebe ma ọ bụ mkpuchi iji belata njikọ na ihe ndị na-emebi ihe.
