Khoyili ya nsimbi ya PPGI leyi nga na ti-PPGI leyi nga na ti-PPGI ta xiyimo xa le henhla i xitirhisiwa xa nsimbi xa le henhla lexi endliweke hi vunjhiniyara eka switirhisiwa leswi lavaka ku ringanisela ka ku lwisana na ku bola, ku vumba, na vuxongi lebyi hetiweke ka ha ri emahlweni. Yi endliwa hi ku tirhisa galvanization ya hot-dip leyi yaka emahlweni (Z60-Z275G zinc coating), coil yi na topcoat ya polymer leyi pendiweke ka ha ri emahlweni (polyester, SMP, kumbe PVDF) leyi tirhisiwaka eka substrate ya nsimbi ya khaboni yo tala (SPCC/SGCC grades), leswi herisaka xilaveko xa ku pendiwa ka le ndzhawini.
Endlelo ra nsirhelelo wa swiphemu swimbirhi—xisekelo lexi fuweke hi zinc xa ku lwisana ni ku bola ka magandzelo ni khumbi ra le henhla ra polymer leswaku ri tiya hi mihlovo—ri endla leswaku ri va lerinene eka ku endliwa ka swilo leswikulu eka ku aka, switirhisiwa ni tiindasitiri ta timovha. Yikumeka hi vukulu kusuka eka 0.15mm kuya eka 2.5mm na ku anama kuya fika eka 1250mm, coil yi seketela roll-forming, stamping, na ku tsema hi thyaka ra swilo leswintsongo.
Swihlawulekiso
Sisiteme ya nsirhelelo wa swiphemu swimbirhi : .
Hot-dip galvanized substrate : zinc coating (Z60 for indoor, Z275 for coastal) yi vumba xisirhelelo xa magandzelo, yi sirhelela nsimbi hambi loko vuandlalo byi khwaxa kumbe ku tsemiwa.
Topcoat leyi pendiweke ka ha ri emahlweni : Swifunengeto swa polyester (waranti ya malembe ya 10) ku tirhisiwa hi ku angarhela; Swifunengeto swa PVDF (waranti ya malembe ya 20) ya ku hlangana na UV swinene, ku tiyisisa ku hlayisiwa ka mihlovo ya nkarhi woleha eka tindzhawu ta mananga/ti tropical.
Xivumbeko xa giredi ya tiindasitiri : .
Ku hlayisa 95% wa ductility endzhaku ko penda, leswi endlaka leswaku ku va na ku dirowa loku dzikeke eka swivumbeko swo rharhangana (xikombiso, ti fenders ta mimovha, tiphaneleni ta nyangwa wa firiji) handle ko peta delamination.
Ku tiyisela ka ku tiya loku tiyisiweke (+/-0.01mm) switiyisisa matirhelo yofana eka milayeni ya vuhumelerisi ya xiothomethi, ya nkoka eka swiphemu swa precision.
Ku tirha kahle ka phurosese : .
Yi phakeriwa eka ti coils letikulu (5-20 tons) na slitting yo hlawula kuya eka custom widths (minimum 300mm), leswi hungutaka nkarhi wo yima eka ti roll-forming lines hi 30%.
Pre-finished surface yi herisa magoza ya post-fabrication painting, leswi hlayisaka 40%+ eka vatirhi na coating costs loko swipimanyisiwa na nsimbi yoka yinga swekiwanga.
Ku landzelela ka misava hinkwayo : .
Yi fikelela swiyimo swa ISO 14682, ASTM A924, na EN 10169, ku tiyisisa ku ringanana eka tiphurojeke ta matiko ya misava (xikombiso, switirhisiwa swa EU, tifektri ta le Dzongeni-vuxa bya Asia).
Swifunengeto swa VOC swa le hansi swi fambisana na milawu ya California ya Carb II, leyi hlayisekeke ku tirhisiwa eka miako ya vutshamo na dyondzo.
Xikombelo
Indasitiri yo aka : yi endla ti trusses ta le henhla ka lwangu, ku pfariwa ka rirhangu, na tifureme ta nsimbi ta makaya ya prefab (xikombiso, tindlu ta modular eJapani) na swivala swa tiindasitiri (xikombiso, Amazon Fulfillment Centers).
Switirhisiwa swa le kaya : Tiphaneli ta tifomo ta tifiriji (xikombiso, Samsung’s stainless steel-look finishes), michini yo hlamba, na switirhisiwa swo hunguta moya, ku lwisana na girisi ya le khixini na tikhemikhali to hlantswela.
Swiphemu swa mimovha : Yi humesa mimiri ya tilori (xikombiso, ti semi-trailer ta Volvo), madzovo ya ti trailer, na swikhomela-ndhawu swa le ndzeni, na Z275 coating leyi sirhelelaka eka munyu wa le magondzweni en’walungwini wa Europe/Canada.
General Fabrication : Swikahle eka fanichara ya nsimbi (xikombiso, IKEA Storage Solutions), swikoweto, na HVAC ductwork, leswi nyikaka ku ringanisela loku nga durhiki ka ku tiya na vuxongi.
FAQ .
Q: Ndzi hlawula njhani exikarhi ka SMP na PVDF Topcoats .?
A: SMP (Silicone-modified polyester) yi lulamerile eka tindzhawu ta ti indasitiri leti nga na ku hlangana na tikhemikhali to olova; PVDF yi hlohleteriwa eka tindzhawu ta le ribuweni/mananga leti lavaka ku lwisana lokukulu na UV.
Q: Xana coil yi nga tirhisiwa hi ku kongoma hi ku hlangana na khonkhriti .?
A: Ina, kambe chela primer ya bituminous ku sirhelela matlhelo lama tsemiweke eka alkaline corrosion, ngopfu ngopfu eka ti foundation piles na makhumbi yo khoma.
Q: Xana vutomi lebyi tolovelekeke i yini eka ndhawu ya tiindasitiri ta le ribuweni .?
A: Z275 na PVDF coating yi teka 15-20 wa malembe; Ku basisiwa ka nkarhi na nkarhi ku susa soot ya ti indasitiri swinga lehisa vutomi bya ntirho hi 25%.
Q: Xana fektri yi nyika ku fambisana ka mihlovo eka tilogo ta nhlangano .?
A: Ina, hi nyika ku fambisana ka mihlovo ya Pantone/Ral na ku tiyisela ka ΔE ≤1.0, leswinene eka tiphurojeke ta mabindzu leti fambisanaka na brand (xikombiso, ku fuleriwa hi ndhawu yo dyela eka yona ya McDonald).
