Dab tsi yog thawj cov ntawv thov ntawm kev lag luam thermal butter thaiv txhuas txhuas ntawv ci?
Industrial thermal insulation aluminum foil is widely used in HVAC systems, pipelines, and industrial equipment to reduce heat transfer. Nws ua haujlwm ua qhov thaiv hluav taws xob hluav taws xob hauv tsev, xav txog 97% ntawm cov thermal hluav taws xob. Cov ntawv ci kuj tseem siv nyob rau hauv ib lub aerospace rau kev tswj qhov kub thiab txias Nyob rau hauv kev lag luam hauv tsheb, nws omater tshem tawm cov tshuab nqus thiab roj teeb roj teeb. Tsis tas li ntawd, nws tiv thaiv cov khoom siv hluav taws xob rhiab los ntawm overheating hauv kev lag luam machinery.
Yuav ua li cas txhuas ntawv siv cov thermal rwb thaiv tsev ua haujlwm?
Aluminium ntawv ci qis dua emissivity cov npoo av minimizes radiant thaum tshav kub hloov los ntawm kev cuam tshuam infrared vuag. Nws cov qauv nyias nyias, lub teeb yuag tawm rau kev sib koom ua ke yooj yim nrog lwm cov ntaub ntawv rwb thaiv tsev xws li ua npuas ncauj. Cov hlau lub siab thermal conductivity pab faib kom muaj tusyees kub thaum siv hauv cov tshuab ntau. Ntawv ci Laminates nrog cov yeeb yaj kiab polymer tsim cov vapor cov teeb meem los tiv thaiv cov hws. Cov khoom no ua rau nws tsis tseem ceeb rau kev siv hluav taws xob muaj zog.
Yuav ua li cas alloy cov qib kheev siv rau kev lag luam thermal rwb thaiv tsev ntawv ci?
Alloy 1100 (99% ntshiab aluminium) yog qhov nyiam rau nws cov zoo heev corrosion tsis kam thiab muaj peev xwm. Alloy 1235 muaj kev cuam tshuam zoo dua vim kev ua kom siab dua vim muaj kev coj dawb huv (99.35% AL). Rau cov ntawv thov siab kub (txog 300 degree), alloy 8011 nrog hlau \/ silicon additives muab zog zog. Aerospace cov ntawv thov feem ntau siv alloy 5052 rau nws cov nkees tsis kam. Qhov kev xaiv yog nyob ntawm thermal, tshuab, thiab ib puag ncig yuav tsum tau ua.
Cov kev kho hniav twg txhim kho cov ntawv nyiaj lub rwb thaiv tsev diculation?
Anodizing tsim cov tshuaj oxide tuab rau kev kub siab heev (txog 650 degree). Polymer txheej (piv txwv li, acrylic lossis polyester) tiv thaiv cov tshuaj corrosion hauv cov chaw muaj kev lag luam. Cov qauv embossing nce cov cheeb tsam kom zoo dua adhesion mus rwb thaiv tsev substrates. Qee cov foils feature ceramheres kom txo thermal bridging. Cov kev kho no txuas txoj kev pabcuam lub neej nyob hauv cov mob hnyav xws li cov roj ua dua tshiab lossis cov nroj tsuag hluav taws xob.
Yuav ua li cas Thermal rwb thaiv tsev ntawv ci raug ntsia rau kev ua tau zoo?
Nco ntsoov nruab cov sab uas muaj kev cuam tshuam rau cov kev kub kub kom ua kom loj hlob loj tshaj plaws hluav taws xob cuam tshuam. Kev sib tshooj sib tshooj los ntawm tsawg kawg 50mm thiab foob nrog qhov ntsuas kub siab aluminium. Zam kev ntsuas cov ntawv ci kom tswj kev ua pa tawm ntawm cov rwb thaiv tsev. Siv cov kws kho tshuab hluav taws xob tau tshwm sim tiv thaiv kom tiv thaiv cua sov los ntawm cov neeg hlau. Kev tshuaj xyuas ib txwm yuav tsum kuaj xyuas lub kua muag, oxidation, lossis delamination hauv thaj chaw co-kev co.
