Corrugated Ru Tsev Ntawv

Corrugated Ru Tsev Ntawv yog ib daim ntawv ua los ntawm cov xim ua los ntawm cov xim {{}}} coated steel ntawv uas yog dov thiab txias} bent mus rau ntau yam corrugated. Daim ntawv no ua ke ntawm kev zoo nkauj thiab corrosion tsis kam ntawm cov xim- txheej txheem kho kom zoo nkauj thiab sab nraum zoov thiab lwm daim teb.

1. Cov khoom lag luam raw (suav nrog kev ua tiav ntawm ntau cov ntaub ntawv raw thiab cov ntaub ntawv tso tawm):

(1) Cov khoom siv hauv paus -}} txias- rolled steel sawb;

(2) txheej - aluminium- tooj liab {} Chromium Iron Shory / Stromium Deg Kho Mob Deg Kho Mob Degure Tus Neeg Saib Xyuas.

(3) Txheej - epoxy resin primer + acrylic topcoat;

(4) Tus neeg saib xyuas tus neeg sawv cev - epoxy diluent / polyurethane nplaum thiab kuab tshuaj.

2. Ua kom → thermoforming → kev kuaj pom → Ntim → Ntim.

Cov ru tsev hlau yog dav siv hauv kev lag luam thiab cov tuam tsev lag luam vim lawv cov nqi pheej yig thiab tsis tu ncua, tab sis lawv yuav tsum tau tu ncua ntev kom ntseeg tau ntev {0} {term kev ua tau zoo. Cov hauv qab no yog cov kev txiav txim siab tseem ceeb rau kev txij nkawm hlau:

Kev tu thiab tshuaj xyuas

Tu tag nrho:

Tshawb xyuas lub ru tsev tsawg kawg ib zaug txhua lub caij kom tshem tawm cov nplooj, plua plav, thiab lwm cov khib nyiab.

Ntxuav lub ru tsev nrog a 5% sodium hypochlorite daws, cia nws zaum li 20 feeb, tom qab ntawd yaug nws nrog lub hose.

Ntxuav lub plab tsis tu ncua (tsawg kawg peb zaug hauv ib xyoos) kom tiv thaiv kev txwv thiab dej tsub zuj zuj.

Tshuaj Tiv Thaiv Kev Nyab Xeeb:

Tswj peb cov ntsiab lus ntawm kev sib cuag (tsawg kawg yog ib txhais tes thiab ob txhais taw) thaum nyob ntawm tus ntaiv.

Sawv ze rau cov ntoo hlau rau kev ruaj khov thaum taug kev, thiab ntiav tus kws tshaj lij yog tias tsim nyog.

Nyob ib puag ncig ib puag ncig tswj hwm:

Mowing the roof Remove branches near the roof to prevent leaf accumulation and algae growth. Keep trees and shrubs a sufficient distance from the roof (>3m for trees and >1.5m rau shrubs).

Ii. Anti - kev kho corrosion

Kev Kho Mob:

Kho cov xeb hauv 24 teev ntawm kev nrhiav pom los tiv thaiv kev tsim cov roj teeb muaj xeb.

Me xeb (<30% area): High-pressure clean, then sand. Apply an anti-rust primer (such as epoxy zinc yellow) and two coats of fluorocarbon topcoat.

Txo kev xeb (30% -50%): Txiav txim siab ib nrab hloov. Kev hloov hloov tam sim yog kev pom zoo rau thaj chaw khaws cov khoom tseem ceeb.

Severe rust (>50% lossis deformation): Ua tiav hloov yog qhov tseem ceeb. Plating yog pom zoo. Aluminium - zinc daim (lifespan txuas ntxiv los ntawm 8-10 xyoo)

Corrosion tiv thaiv lub voj voog:

Nqaum ib puag ncig nrog cov siab muaj zog: check zaj duab xis thickness txhua peb lub xyoos. Yog tias poob ntau dua 30%, ua kev ua haujlwm hauv cheeb tsam.

Nyob rau hauv ib puag ncig qhuav: tshuaj xyuas tuaj yeem txuas ntxiv mus rau tsib xyoos.

Ziag taub tshaj txoj kev hloov kho siab ntev: 8-10 xyoo (kho raws li cov kev mob corrosion).

Corrosion tiv thaiv cov xaiv:

Siv cov txheej txheem sib xyaw ntawm epoxy zinc - Primer nplua nuj (zinc cov ntsiab lus ntau dua los yog sib npaug rau 80%) + Polyurethane Topcoat. Sandblast rau sa 2.5, roughness 40-70μm, tag nrho cov zaj duab xis qhuav ntau dua lossis muaj sib npaug rau 250μm.

III. Txheej Txheem Txheej Txheem Kev Nyab Xeeb

Weld Taw Soj Ntsuam Xyuas Weld:

Siv Infrared Thermal Ntsuas Technology kom nrhiav tau weld disromacts, nce kev tshuaj xyuas kev ua tau zoo los ntawm 300%.

Ultrasonic qhov khuam detectors tuaj yeem nkag mus rau 50 hli tuab tuab daim hlau los kuaj pom cov kab nrib pleb nrog ib qho yuam kev ntawm<0.5%.

Tsom rau kev kuaj xyuas k -} Groove Welds raug rau kev hloov chaw kom ntseeg tau tias tag nrho cov kev nkag mus.

Saib xyuas:

Siv tag nrho cov chaw nres tsheb kom ntsuas qhov kev hloov chaw ntawm cov khoom tseem ceeb ua ntej lub caij los nag txhua xyoo.

Rau cov loj -} kev teeb steel, saib xyuas ib qho taw tes txhua 20m nrog qhov tseeb ntawm ± 3mm.

Qhov tsis muaj cai nruab nrab -} span deflection ntawm cov nqaj hlau crane yog l / 600 (l {{2} {late). Txhua qhov kev sib tw tshaj qhov kev txwv no yuav tsum tau ua rau cuam tshuam.

Kev Soj Ntsuam Soj Ntsuam:

Torque ntsuas txhua txhua peb lub xyoos. Siv lub wrench los tshawb nrhiav pob qij txha, tswj lub pre - ua rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau tom ntej 10%.

Siv ib qho kev tsis sib haum tsis muaj zog los tshawb xyuas cov microcacks, thiab ib qho thermal dermal imager los kuaj kom kuaj txias choj.

IV. Waterproofing System txij nkawm

Kev Kho Mob Sib Koom Tes:

Tshawb xyuas lub caj qaum, eaves, thiab ntsia hlau pob qij txha rau cov khoob thiab xeb.

Tshem tawm cov detervated sealant thiab kev rov ua dua nrog nruab nrab silicone lossis polyurethane fab.

Kev Kho Ob Leeg Ua ke: Tom qab tu, thov ib qho nano - Cov xeb dej tsis muaj xeb thiab npog nrog polyester secting.

Cov txheej txheem kev hloov hluav taws xob:

Tshawb xyuas cov kev sib tshuam ntawm cov xim - coated steel phaj nrog cov gutter facade, thiab lwm thaj chaw rau cov kab nrib pleb.

Kev huv huv si. Tshem tawm cov khoom siv sealant thawj thiab lub cim nrog xis mas cug lossis hloov kho cov tshuaj asphalt.

Tom qab thov cov sealant tshiab, thov 250 hli dav butyl daim kab xev kom txhim kho lub foob.

Cov khoom siv dej tsis muaj dej:

Neutral silicone nplaum: 15-20 xyoos tiv thaiv, tensile lub zog ntau dua los yog sib npaug, haum rau qhov kub ntawm 40-1 qib.

Polyurethane nplaum: rov qab zoo heev, elongation thaum tawg txog 400%, haum rau cov pob qij txha dynamic.

Butyl daim kab xev: nrawm adhesion, 5-8 xyoo tiv thaiv, tsim nyog rau cov ntsia hlau khi.

V. Huab Cua Raug Txawv Tebchaws

Typhoon tiv thaiv:

Txais yuav tsim nyog lub ru tsev vov thiab ntxiv dag zog rau cov qauv kev txhawb nqa.

Nruab cua - ionistant clips lossis buckles kom txo qis kev pheej hmoo ntawm cua {}- tawm.

Ntxiv rau thauj tog rau tog rau tog

Tshawb xyuas thiab txhawb cov kev nkag mus rau kev tso sab nraum zoov thiab skylights ua ntej Typhoon tuaj txog.

Los daus npaj:

Tam sim ntawd ntshiab daus las ntau dua 30 cm (thauj khoom ceeb toom chaw pib).

Soj cov qauv steel rau xeb thiab ua raws sij hawm anti - rust ntsuas.

Ntev -} ntev qauv yuav tsum tau tshuaj xyuas cov kev soj ntsuam thiab kev tshem tawm daus.

After a snowstorm, inspect structural deformation, especially the verticality of steel columns (deviations >3 ‰ Yuav tsum kho).

VI. Kev Txij Nkawm Kev Taw Qhia

Hauv -} Tsom-ntsuam xyuas lub voj voog:

Ua kev soj ntsuam tshaj lij txhua 5 xyoos. Hauv - Kev Txij Nkawm Kev Tshawb Nrhiav cov txheej txheem kev tshuaj xyuas, kev kuaj cov khoom siv, thiab kev ua haujlwm zoo.

Kho kev txiav txim siab them nqi:

Tag nrho tus nqi rov qab kho dua li tsib -} xyoo xyoo yog feem ntau 1.7 lub sij hawm ntawm kev hloov ncaj qha. Rau kev ntsuas lossis muaj xeb hnyav, nws pom zoo kom ntsuas qhov kev siv hluav taws xob ntawm kev hloov pauv.

Siv Kev Tshuaj Xyuas Zoo:

Ceev faj ntawm "pheej yig kho" ntxiab: tsawg {{{}} tapping screws yuav tsis muaj xeb thiab perforate nyob rau hauv ob xyoos. Zam txhob "dej lim" scams: 90% ntawm polyurethane txheej yuav chalk tom qab 18 lub hlis.

Los ntawm kev ua raws cov txheej txheem txij nkawm saum toj saud, lub neej ntawm lub ru tsev steel tuaj yeem txuas ntxiv thaum txo qhov kev pheej hmoo ntawm kev puas tsuaj sai. Nws raug nquahu kom khaws cov ntawv npaj tu, sau tseg txhua qhov kev kuaj xyuas thiab kev ua kom muab cov ntaub ntawv saib xyuas tom ntej.
