Nrog rau ntau tshaj 13 xyoo ntawm kev mob siab rau kev tsim khoom hauv cov laj kab hlau, Pauleen tau ua tiav kev ua tiav los tiv thaiv -corrosion system uas mus deb tshaj li qub galvanizing lossis pleev xim yooj yim. Peb txoj hauv kev yog hauv paus hauv metallurgical precision, nruj txheej txheej, thiab ntau- txheej txheej txheej txheej txheej txheem- kom ntseeg tau tias txhua lub laj kab tawm hauv peb lub Hoobkas tuaj yeem tiv thaiv ntsev tsuag, UV hluav taws xob, thiab av noo ntau xyoo.
Lub hauv paus ua rau: Vim li cas feem ntau cov laj kab hlau tsis ua haujlwm
Cov laj kab laj kab hlau feem ntau vam khom ib txheej ntawm ncej-galvanization lossis cov hmoov nyias nyias siv rau ntawm qhov chaw npaj me me. Qhov no ua rau:
Underfilm corrosion vim tsis txaus phosphate conversion txheej.
Cathodic delamination ntawm txiav ntug thiab xyaum qhov.
Filiform corrosion nyob rau hauv lub txheej nyob rau hauv ib puag ncig humid.
Weld seam oxidation qhov twg zinc txheej yog hlawv tawm thaum fabrication.
Pauleen's 13-Year Anti-Corrosion System - Txheej los ntawm Txheej
Peb tsis yog npog qhov teeb meem xwb; peb tshem tawm nws los ntawm substrate mus.
1. Base Material Selection – High-Strength Low-Alloy (HSLA) Steel
Peb pib nrog HSLA steel nrog tswj cov ntsiab lus carbon (tsawg dua lossis sib npaug li 0.12%) thiab qis phosphorus / sulfur qib, txo qhov kev pheej hmoo ntawm intergranular corrosion. Cov hlau yog ua ntej- cov khoom xa tuaj kuaj xyuas siv qhov ntsuas qhov muag pom (OES) kom ntseeg tau tias muaj kev sib raug zoo.
2. Advanced Surface Preparation – Lub hauv paus ntawm Adhesion
Txhua qhov profile tau dhau los ua 7-theem pretreatment txheej txheem:
Alkaline degreasing (tshem tawm tag nrho cov roj zeb thiab cov khoom paug)
Yaug nrog dej deionized
Zinc phosphate nanoceramic conversion txheej - tsim ib txheej microcrystalline (2-3 g / m²) uas txhim kho txheej adhesion thiab qeeb underfilm corrosion
Yaug nrog rov qab osmosis dej (conductivity<20 µS/cm)
Tsis yog -chrome sealing passivation - ib puag ncig tus phooj ywg tsis tau corrosion heev-resistant
Cua kub kom qhuav ntawm 120℃ua ntej txheej
3. Kub-Dip Galvanizing (HDG) - Internal Corrosion Barrier
Hloov ntawm nyias electro-galvanizing, peb siv kub-dip galvanizing ib ASTM A123 / ISO 1461:
Yam tsawg kawg zinc txheej thickness: 85 µm (rau 3-6 hli steel seem)
Txheej hnyav: Ntau dua lossis sib npaug li 610 g / m²
Cov ntawv cog lus metallurgical tsim Fe-Zn alloy txheej (delta, zeta, thiab eta theem), muab kev tiv thaiv cathodic txawm tias qhov chaw raug khawb.
4. Zinc-Nrog Epoxy Primer – Active Edge Protection
Tom qab HDG, peb siv zinc-nplua nuj epoxy primer (88% zinc plua plav los ntawm qhov hnyav hauv zaj duab xis qhuav) rau txhua qhov chaw, tshwj xeeb tshaj yog qhov tseem ceeb ntawm weld seams thiab punched qhov. Cov primer no muab kev tiv thaiv anodic sacrificial thiab txuas txhua qhov micro-porosity hauv txheej galvanized.
5. Polyester lossis PVDF Topcoat - Huab cua Shield
Qhov kawg txheej yog cov hmoov txheej ruaj khov:
Option A (standard): Weather-resistant polyester powder – 80–100 µm thickness, >600 h ntsev tsuag tsis kam (ASTM B117) nrog<1 mm creep from scribe.
Option B (coastal/industrial): PVDF (polyvinylidene fluoride) coating – 70/30 Kynar 500®-based, providing >2,000 h ntawm QUV-A nrawm huab cua nrog Tsawg dua lossis sib npaug rau 1 ΔE xim hloov.
Cov txheej yog siv rau hauv lub computerized electrostatic spray lub rooj, ua raws li los ntawm kev kho nyob rau hauv ib tug gradient qhov cub (nce hlau kub 200℃rau 10 feeb), ua tiav ntoo khaub lig-txuas kev sib txuas ceev uas thaiv cov dej noo thiab chloride ions.
6. Seam & Joint Sealing - Cov Ntsiab Lus Tsis Pom Zoo
Tag nrho cov welded pob qij txha yog re-kho nrog ib tug txias-galvanizing compound (95% zinc) tom qab vuam, ces dhau -coated nrog epoxy-polyester hybrid hmoov. Peb kuj siv cov roj hmab gaskets ntawm cov ntsiab lus sib dhos los tiv thaiv galvanic corrosion ntawm cov hlau sib txawv.
Validated Performance - Tsis yog Cov Lus Cog Tseg xwb
Pauleen's steel laj kab system tau raug sim ntawm nws tus kheej:
Ntsev tshuaj tiv thaiv (ASTM B117): Tshaj 1,500 teev yam tsis muaj xeb liab.
Cyclic corrosion test (ASTM G85 – Annex A5): 50 cycles – no blistering, no scribe creep >1.5 hli.
Impact resistance: Kev cuam tshuam ncaj qha 20 hauv -lb (ASTM D2794) yam tsis muaj tawg.
Humidity resistance (ASTM D2247): 1,000 teev - tsis muaj delamination.
Pauleen 13-Xyoo Field Track Record
Peb cov laj kab zinc hlau qub tshaj plaws, yos rov qab rau xyoo 2011, tseem muaj kev pabcuam hauv ntug dej hiav txwv Zhejiang thiab thaj chaw muaj kev lag luam hauv av. Peb niaj hnub ua tom qab- kev tshuaj xyuas kev teeb tsa siv electromagnetic txheej thickness gauges thiab hla- txiav adhesion xeem (ASTM D3359 - rating 5A). Cov txiaj ntsig tsis tu ncua qhia tsawg dua 0.1% nto xeb tshaj 13 xyoo.
Vim li cas thiaj tso siab rau Pauleen ua koj tus neeg muag khoom?
Integrated manufacturing: Los ntawm steel yob txoj kev mus rau txheej thiab sib dhos - tag nrho nyob rau hauv ib lub ru tsev. Tsis muaj subcontracting txhais tau tias tag nrho traceability.
ISO 9001: 2015 & ISO 12944 ntawv pov thawj (kev tiv thaiv corrosion ntawm steel qauv).
Customizable: Peb kho cov txheej thickness, xim (RAL lossis kev cai), thiab laj kab tsim (ornamental, welded mesh, los yog picket) rau koj qhov project corrosivity qeb (C3 rau C5-M raws li ISO 9223).
Txais tos & OEM txais tos - Peb xa khoom thoob ntiaj teb nrog cov khoom ntim tshuaj tiv thaiv - xeb (ntug tiv thaiv, VCI zaj duab xis, thiab plywood crates).
Nres Kev Npaj Rau Kev Hloov. Pib Lub Tsev Rau Ib Tiam.
Tsis txhob cia zais qhov corrosion noj rau hauv koj lub koob npe nrov lossis nyiaj txiag. Nrog Pauleen's 13-xyoo tshwj xeeb paub- yuav ua li cas, koj lub laj kab steel tom ntej yuav tsis zoo rau kev xa khoom xwb-nws yuav nyob twj ywm zoo nkauj thiab zoo nkauj ntev tom qab cov kev xaiv pheej yig dua tau hloov mus rau xeb.
