Corrosion pib los ntawm qhov chaw raug thiab ua rau cov khoom puas los ntawm txheej. Ib txheej txheej txheej yuav tiv thaiv ntau dua. Nws tuaj yeem khaws lub hauv paus hlau los ntawm corrosion, tshuaj lom neeg puas tsuaj, thiab UV teeb kom ntev nws lub neej kev pab. Nyob rau tib lub sijhawm, nws tuaj yeem ua rau cov hlau nto du thiab zoo-zoo. Yog vim li cas cov txheej txheem txheej yog tsim nyog.
Piv txwv li,xim coated steel (PPGIthiabPPGL) muaj zinc txheej lossis Al-Zn txheej, prime txheej, thiab txheej tiav. Feem ntau, ob sab yog coated. Muab piv rau cov txheej saum toj kawg nkaus, txheej txheej rau sab nraub qaum yog hu ua rov qab txheej. Cia peb tshuaj xyuas qhov ua haujlwm ntawm txhua txheej xim.
Xim Coated Steel Structure
Hom Xim Xim
Cov xim siv feem ntau yog PE, SMP, PVDF, HDP. Hauv qab no yog cov lus qhia luv luv rau cov xim.
PE (polyethylene)
Nws muaj kev ua haujlwm zoo thiab nws lub peev xwm huab cua zoo ua tau raws li qhov yuav tsum tau ua ntawm lub tsev sab nrauv. Nws feem ntau yog siv rau ntau yam ntawm cov tsev lag luam, cov tsev lag luam xws li lub ru tsev, thiab cov phab ntsa sab nraud.
SMP (Silicone Hloov Polyester)
Nws muaj ultra-weathering pigments los xyuas kom meej qhov ci ntsa iab ntawm cov xim. Ntxiv mus, SMP xim muab cov qauv silicone tshwj xeeb los txhim kho cov tawv tawv ntawm txheej uas tuaj yeem tsis tsuas yog ua kom hnav tsis kam thiab hlau khawb tab sis kuj tiv taus qhov sib sib zog nqus ntawm stamping.
PVDF (polyvinylidene fluoride)
PVDF xim muaj ntau dua 70% ntawm cov ntsiab lus polyvinylidene fluoride, Nws muab cov txheej txheem huab cua zoo, kua qaub thiab alkali, thiab kev ua haujlwm ntawm ib puag ncig. Cov xim PVDF siv cov xim zoo nkauj inorganic ceramic los thaiv UV thiab tuav cov xim gloss rau txheej.
HDP (High durability polyester)
HDP muaj xim ntau dua li PVDF. Vim yog cov xim no tshwj xeeb polyester qauv thiab zoo hydrolysis tsis kam, HDP kuj muaj tshuaj tiv thaiv zoo heev thiab kav ntev.
Koj tuaj yeem xaiv cov xim raws li qhov xav tau, kev pabcuam ib puag ncig, koj cov peev nyiaj, ib puag ncig, thiab lwm yam.
