Cov ntaub ntawv vov tsev yog "thawj kab ntawm kev tiv thaiv" rau cov tsev: lawv yuav tsum tiv taus lub hnub thiab nag, tiv taus qhov kub thiab txias, thiab tseem ua tau zoo hauv hluav taws kub, rwb thaiv tsev kub, thiab tiv thaiv corrosion. Nyob rau hauv xyoo tas los no, cov vuas hluavtaws, nrog rau lawv lub teeb yuag, lub zog siab, ntev - xim ntev, thiab yooj yim installation, tau tawg tawm ntawm cov tsoos camp ntawm cov xim hlau vuas thiab cov vuas glazed, dhau los ua ib qho kev xaiv nrov rau cov chaw tsim khoom, warehouses, tus kheej- ua tsev, thiab "flat-to{" ru tsev.
Txawm li cas los xij, qhov zoo ntawm "cov vuas vuas" ntawm kev ua lag luam txawv heev, nrog rau cov nqi ntawm ib lub kaum rau ntau kaum ntawm yuan ib square meter.
Dab tsi yog qhov txawv? Koj yuav tsum nrhiav dab tsi thaum yuav khoom? Kab lus no piav qhia qhov no kom meej los ntawm peb qhov loj me: co- txheej txheem extrusion, kev siv cov qauv, thiab cov ntsiab lus tseem ceeb.
I. Synthetic Resin Vuas yog dab tsi?
Synthetic resin vuas tsis yooj yim li "cov vuas yas."
High-cov khoom siv hluav taws xob zoo vov tsev vuas siv peb- txheej co-extrusion qauv, los ntawm sab nraud hauv:
ASA txheej txheej (kwv yees li 0.15 ~ 0.2mm): Acrylonitrile-styrene-acrylate copolymer, txiav txim siab cov nplais huab cua tsis kam, lightfastness, thiab xim tuav;
Xim txheej: Co-extruded thiab fused nrog ASA txheej, kom ntseeg tau xim xim thiab tiv thaiv tev;
PVC / UPVC puag txheej: Muab lub zog, toughness, thiab zuag qhia tag nrho rigidity, ua hauj lwm raws li cov pobzeb load-cov kabmob qauv.
Hauv luv luv: txheej txheej saum npoo ua kom "hnub-tiv taus thiab ploj mus- tiv taus," thaum lub hauv paus txheej ua kom "kev cuam tshuam thiab deformation tsis kam." Ob leeg yog co-extruded rau hauv ib chav tsev, tshem tawm qhov tsis zoo ntawm cov tshuaj tsuag ib txwm siv- cov vuas pleev xim uas "faus tom qab ob xyoos."
II. Resin Vuas vs. Corrugated Steel Vuas vs. Glazed Vuas: Lub Rooj To taub
Cov khoom sib piv: ASA Synthetic Resin Vuas, Corrugated Steel Vuas, Glazed Vuas
Lifespan: 25-30 xyoo (xim kav) 5-10 xyoo: nquag xeb thiab txheej tev Ntau tshaj 30 xyoo, tab sis hnyav heev
Luj: Kwv yees li . 4-6 kg / m², lub teeb yuag Lub teeb sib xws tab sis nquag xeb Kwv yees li . 40-60 kg / m²
Corrosion Resistance: Resistant rau cov kua qaub, alkalis, thiab ntsev tsuag, haum rau cov ntug hiav txwv dej / tshuaj lom neeg yooj yim corroded los ntawm corrosive gases Zoo huab cua tsis kam tab sis prone rau brittleness
Rwb thaiv tsev Performance: Tsawg thermal conductivity, pom thaum tshav kub kub rwb thaiv tsev nyob rau hauv lub caij ntuj sov Fast tshav kub nqus, muaj zog tshav kub conduction Nruab nrab tshav kub rwb thaiv tsev
Hluav taws kub Resistance: mus txog B1 theem (tus kheej-extinguishing) Tsis yog-flammable tab sis ceev kub hloov tsis tau-flammable
Kev tsim kho nyuaj: Lub teeb yuag, tuaj yeem drilled thiab txiav, ceev qhuav dai Yuav tsum tau tsim cov cuab yeej thiab kev tiv thaiv xeb Yuav tsum tau cement mortar ntub kev tsim kho
Tus Nqi Tag Nrho: Nruab nrab mus rau siab, tab sis kev saib xyuas - pub dawb thiab ua haujlwm - txuag tus nqi pib qis, nqi kho tom qab siab
Cov khoom siv siab thiab nqi zog
Xaus: Rau cov haujlwm uas nrhiav kev mus sij hawm ntev- txij nkawm- kev ua haujlwm pub dawb, kev tiv thaiv corrosion, thiab rwb thaiv tsev kub, cov vuas hluavtaws muaj cov nqi zoo dua tag nrho- kev ua tau zoo. Cov vuas xim hlau yog pheej yig dua thaum pib, thaum cov vuas glazed ua tau zoo hauv kev zoo nkauj ib txwm, tab sis lawv qhov hnyav thiab cov nqi zog yog qhov tsis zoo.
III. Vim li cas "co- txheej txheem extrusion" yog ib txoj kab sib faib zoo?
Ob txoj hauv kev uas tsis tshua muaj nqi -cov vuas cov vuas nqi ntawm lub khw txiav cov ces kaum:
1. Tsis txaus lossis tsis txaus nyias ASA txheej txheej - siv PVC zoo tib yam rau cov xim ncaj qha, ua rau fading thiab hmoov tsis pub dhau rau lub hlis mus rau ib xyoos;
2. Cov khoom siv rov ua dua tshiab - muab cov khoom siv rov ua dua tshiab rau hauv lub hauv paus txheej, ua rau tsis muaj zog, brittleness, thiab tsw ntxhiab tsw.
Cov khoom lag luam tsis tu ncua nruj me ntsis ua raws li ib qho - sij hawm co- txheej txheem extrusion molding, sib txuas ASA txheej txheej thiab PVC / UPVC puag txheej. Qhov no molecular - qib kev sib txuas ntawm cov nplais saum npoo thiab txheej txheej tshem tawm qhov xav tau rau txheej "veneer" cais, yog li ua tiav cov hauv qab no:
Huab cua Resistance thiab Xim Retention: ASA txheej tiv thaiv UV kev laus, ua kom cov xim ruaj khov rau kev siv sab nraum zoov;
Kev Tiv Thaiv Hluav Taws Xob: Cov pa oxygen siab siab, tus kheej - tua hluav taws thaum tshem tawm cov nplaim hluav taws, tsis yog -combustible, thiab tsis drip cov khoom siv hluav taws xob;
Corrosion Resistance: Kev tiv thaiv zoo heev rau cov kua qaub los nag, tshuaj tsuag ntsev, thiab cov pa roj carbon monoxide, tsim nyog rau thaj chaw ntug dej hiav txwv thiab chaw ua haujlwm tshuaj lom neeg;
Thaum tshav kub kub rwb thaiv tsev thiab suab nrov txo: Tsawg thermal conductivity, ua ke nrog ib tug corrugated pobzeb qauv, ua rau lub teeb nyob rau hauv lub tsev kub nyob rau hauv lub caij ntuj sov, piv rau corrugated steel ru tsev, thiab superior suab nrov txo nyob rau hauv rainy huab cua;
Lub teeb yuag thiab siab -Lub zog: hnyav li ntawm 1/10 ntawm cov vuas ib txwm, nws txo qis lub ru tsev load thiab steel qauv, txo lub sij hawm tsim kho.
IV. Cov qauv siv tseem ceeb (Yuav tsum tau nug txog kev yuav khoom)
Ua raws li cov khoom siv hluavtaws vov tsev pobzeb cov khoom yuav tsum muab cov qauv ntsuas rau cov hauv qab no:
GB/T 38360-2019 "Synthetic Resin Roofing Vuas"-Cov txheej txheem tseem ceeb hauv tebchaws rau cov khoom siv hluavtaws vov tsev pobzeb, qhia meej meej cov kev xav tau rau cov tsos, qhov ntev, lub cev thiab lub zog, thiab huab cua tsis kam;
GB/T 14206-2015 "Glass Fiber Reinforced Plastic Corrugated Sheets"-Ib tus qauv siv rau kev txhawb nqa skylight/corrugated sheet khoom;
GB/T 50046-2018 "Standard for Corrosion Protection Design of Industrial Buildings"-Ib qho qauv siv rau kev xaiv cov khoom siv thiab tsim hauv kev tiv thaiv corrosion engineering.
Thaum yuav khoom, thov nco ntsoov thov cov chaw tsim khoom los muab cov ntaub ntawv soj ntsuam thib peb ntawm - tog, tsom rau kev txheeb xyuas: nto ASA thickness, oxygen Performance index ( nplaim taws retardancy rating), poob rauj cuam tshuam kuaj, flexural zog, thiab dag zog ceev cov ntaub ntawv aging.
V. Tej yam tshwm sim ntawm daim ntawv thov
Factory/Warehouse/Steel Structure Buildings: Corrosion-resistant, huab cua-resistant, txij nkawm-dawb, thiab tso cai rau lub teeb pom kev zoo thaum siv nrog cov ntawv vov tsev;
Nyob deb nroog tus kheej-ua Tsev / Villa Sloping Roofs: Cov xim nplua nuj (maroon, tsaus ntsuab, xiav xiav, thiab lwm yam), kev ntxhib los mos zoo ib yam li cov ntawv vov tsev, lub teeb yuag txo tus nqi ntawm cov qauv;
Pav ca-rau-Sloping Roof Conversion Projects: Lub teeb yuag, haum rau kev teeb tsa ncaj qha rau ntawm lub ru tsev uas twb muaj lawm;
Corrosive Ib puag ncig zoo li thaj chaw ntug dej hiav txwv, cov nroj tsuag tshuaj, thiab Aquaculture Areas: Resistant rau ntsev tsuag, acids, thiab alkalis, ua rau nws yog ib qho zoo tagnrho hloov rau xim hlau vov tsev ntawv.
VI. Plaub Cov Ntsiab Lus Tseem Ceeb rau Kev Zam Txim Thaum Yuav Khoom:
Xyuas cov txheej txheej saum npoo: Paub meej tias nws puas yog ASA co- txheej txheej extruded; tsis lees paub "xim PVC masquerading li ASA";
Xyuas Cov Khoom Siv Zoo: Xaiv cov khoom siv nkauj xwb los ua cov khoom siv hauv paus; ceev faj ntawm cov khoom siv rov ua dua tshiab (muaj ntxhiab tsw, tsis muaj zog, ua rau tawg);
Tshawb xyuas cov qauv: Tau txais daim ntawv ntsuam xyuas ua raws li GB / T 38360-2019, thiab txheeb xyuas cov nplaim hluav taws kub nyhiab thiab cov ntaub ntawv laus;
Sib piv Thickness thiab Corrugation: Tus qauv thickness yog 2.5 ~ 3.0mm. Corrugation suab thiab qhov siab cuam tshuam rau cov kua dej thiab cua tsis kam; xaiv raws li kev nyab xeeb hauv zos thiab ru tsev nqes hav.
