Puas yog koj txhawj xeeb txog cov ntaub ntawv vov tsev warping nyob rau hauv lub hnub los yog tsev xog paj ua cov cuab yeej cua sov uas tsis tuaj yeem tiv taus? Ntau cov khoom siv glazing tsis tuaj yeem ua haujlwm siab thermal loads, ua rau cov txheej txheem deformation thiab tsis muaj zog efficiency. Kev nkag siab txog kev tshawb fawb tom qab polycarbonate qhov kev tiv thaiv tshav kub yog qhov tseem ceeb rau kev xaiv cov khoom siv ruaj khov, siab -cov khoom siv hauv tsev.
Cov nplooj ntawv polycarbonate tiv taus cua sov los ntawm kev sib xyaw ua ke ntawm cov iav siab hloov pauv kub (145℃-150 degree), tshwj xeeb UV co-extrusion uas cuam tshuam txog hluav taws xob infrared, thiab ntau lub tsev uas muab U-tus nqi qis. Thaum cov ntaub ntawv sib tw soften ntawm 70 degree, polycarbonate tuav nws txoj kev ncaj ncees mus txog 120 degree. Los ntawm kev siv 100% nkauj xwb raw cov ntaub ntawv thiab ib txheej 80μm UV, cov nplooj ntawv no tuaj yeem txo qhov kub hauv tsev los ntawm 10-15℃thaum tiv thaiv thermal degradation.
Txhawm rau nkag siab tias vim li cas cov khoom siv no yog qhov kev xaiv zoo tshaj plaws rau kev yuav khoom thiab kev tsim kho thoob ntiaj teb, peb yuav tsum tshuaj xyuas cov ntaub ntawv tshwj xeeb thermal thiab cov txheej txheem engineering uas ua rau nws muaj zog.
Qhov kub siab tshaj plaws polycarbonate tuaj yeem ua li cas?
Polycarbonate yog qhov ua tau zoo - thermoplastic paub txog nws qhov tshwj xeeb thermal stability piv rau cov ntaub ntawv xws li PVC lossis acrylic.
Kev siv tsis tu ncua kub:Polycarbonate tuaj yeem tiv taus qhov kub thiab txias ntawm qhov kub thiab txias-40℃rau +120℃(-40℃F txog 248℃F)tsis muaj qhov poob ntawm lub cev muaj zog.
Thaum tshav kub kub Deflection Temperature (HDT):Nyob rau hauv ib tug load ntawm 1.82 MPa, cov ntaub ntawv resists deformation mus txog135℃- 140 degree.
Iav Transition Temperature (Tg):Cov khoom tsuas yog pib hloov los ntawm lub xeev nruj mus rau lub xeev rubbery ntawm kwv yees li145℃rau 150 degree.
Melting Point:Raws li ib tug amorphous polymer, nws tsis muaj ib tug ntse melting point tab sis ua kua rau kev ua ntawm220℃thiab 250 degree.
Rau kev lag luam vov tsev hauv cov cheeb tsam xws li UAE lossis Central Asia, cov chaw ua haujlwm siab no xyuas kom cov nplooj ntawv tsis sag lossis buckle thaum lub caij ntuj sov siab.
Cov qauv ntawm daim ntawv puas cuam tshuam rau cov rwb thaiv tsev kub?
Cov qauv ntawm lub cev ntawm daim ntawv yog qhov tseem ceeb hauv kev txiav txim siab nws "U-Tus nqi"- qhov ntsuas kub hloov pauv. Tus nqi qis dua U- qhia tias muaj kev rwb thaiv tsev zoo dua.
Multiwall polycarbonate (ntxaib-wall, triple-wall, los yog honeycomb) yog tsim tshwj xeeb rau thermal efficiency. Cov ribs sab hauv tsim "dhau cua" hnab ris. Txij li thaum huab cua yog ib tug tsis zoo conductor ntawm tshav kub, cov khaubncaws sab nraud povtseg ua raws li ib tug natural barrier.
| Daim ntawv hom & Thickness | Qauv | U-Tus nqi (W/m²·K) | Rwb thaiv tsev Efficiency |
| 6mm Multiwall | Twin-wall | ~3.5 - 3.7 | Standard (Greenhouses) |
| 10 hli Multiwall | Honeycomb | ~2.3 - 2.5 | High (Commercial ru tsev) |
| 16 hli Multiwall | X-Structure | ~1.8 - 2.0 | Superior (Industrial) |
| 5mm Khoom Sheet | Pav ca | ~5.1 - 5.3 | High Impact / Tsawg rwb thaiv tsev |
UV co-extrusion tiv thaiv thermal puas?
Thaum tshav kub kub tsis kam yog qhov kub thiab txias; nws yog hais txog kev tswj lub hnub ci hluav taws xob. Lub hnub emits ultraviolet (UV) thiab infrared (IR) rays uas nqa cov thermal zog tseem ceeb.
Reflecting Infrared:Advanced UV co-extrusion, tshwj xeeb tshaj yog thaum thov ntawm lub thickness ntawm80μm, ua raws li daim ntaub thaiv. Nws qhia txog ib feem loj ntawm infrared spectrum, uas yog lub luag haujlwm rau "cov nyhuv tsev cog khoom" hauv cov tsev.
Tiv thaiv Degradation:UV rays rhuav tshem cov saw hlau polymer (duab-oxidation). Yog tsis muaj txheej tiv thaiv, daim ntawv yuav daj thiab ua nkig, poob nws lub peev xwm los tiv thaiv tshav kub.
Co- txheej txheem extrusion:Tsis zoo li cov tshuaj tsuag - ntawm cov txheej txheej, co- cov txheej txheem UV extruded yog fused rau hauv daim ntawv thaum lub sij hawm tsim khoom, kom ntseeg tau tias kev tiv thaiv tsis tev lossis hnav dhau sijhawm.
Kev xaiv xim puas cuam tshuam rau kev nqus cua sov?
Cov xim thiab cov xim ntawm daim ntawv muaj feem cuam tshuam rau Hnub Ci Heat Gain Coefficient (SHGC). Tus nqi no ntsuas ntau npaum li cas hnub ci hluav taws xob nkag mus rau hauv ib lub tsev.
Cov Ntawv Ntshiab:Muab88% -90% lub teeb kis tau tus mobtab sis kuj tso cai rau cov cua sov tshaj plaws. Qhov zoo tshaj plaws rau huab cua txias.
Opal / Dawb:Cov diffuse lub teeb thiab muaj qhov cuam tshuam siab, txo qis SHGC.
Bronze / Grey:Cov tints no zoo heev ntawm absorbing thiab xav txog lub hnub ci zog, feem ntau txo qhov kub ntawm qhov chaw hauv qab los ntawm ob peb degrees.
Thaum tshav kub kub-Stop Additives:Qee cov ntawv zoo tshaj plaws suav nrog cov khoom siv hlau nplaum uas thaiv cov cua sov thaum tuav cov pob tshab siab.
Puas yog polycarbonate zoo dua iav rau cov cua sov?
Nyob rau hauv cov nqe lus ntawm thermal kev ua tau zoo, polycarbonate yog superior rau iav ntawm sib npaug thickness.
Polycarbonate lub thermal conductivity yog kwv yees li0.21 W/m·K, hos iav yog roughly1.05 W/m·K. Qhov no txhais tau tias PC yog ib txwm muaj tsib zaug tiv taus cua sov dua li iav. Tsis tas li ntawd, polycarbonate yog resistant rauthermal shock- nws yuav tsis tawg yog tias ib sab yog kub dua li lwm qhov, ib qho kev ua tsis tiav rau cov iav tempered hauv thaj chaw suab puam.
Cov qauv tsim ua li cas kom ntseeg tau cov cua sov?
Rau B2B cov neeg yuav khoom, qhov zoo ntawm cov ntaub ntawv raw yog qhov kawg txiav txim siab ntawm kev ua haujlwm kub. Siv100% nkauj xwb raw khoomxyuas kom meej tias qhov hnyav molecular ntawm cov polymer yog siab txaus los txhawb nqa qhov kev ua haujlwm ntawm 120 degree. Cov khoom siv rov ua dua feem ntau muaj cov impurities uas txo cov iav hloov pauv kub, ua rau ua tsis tiav ntxov.
