Product Information:
Qhov PERT Tubing no yog peb txheej oxygen-barrier pem teb cua sov yeeb nkab, uas yog tsim los ntawm EVOH oxygen-permeable txheej txheej, nplaum, thiab PE-RT puab txheej.
PE-RT cov khoom siv los ntawm PERT Tubing yog polyethylene (PE) resin nyob rau hauv uas cov qauv molecular yog tsim los qhia ib tug txaus tus naj npawb ntawm kev sib txuas chains kom tso cai rau kev khiav hauj lwm ntawm elevated los yog elevated kub (RT). Cov saw txuas" txuas" cov qauv siv lead ua nyob rau hauv cov polymer ua ke, yog li txhim kho cov khoom xws li kub siab zog thiab kev ua tau zoo, tshuaj tiv thaiv, thiab qeeb tawg propagation kuj.
EVOH oxygen barrier nyob rau hauv PERT Tubing yog ua los ntawm ethanol vinyl cawv los tiv thaiv oxygen diffusion. Oxygen diffusion yog ib qho tseem ceeb heev nyob rau hauv pem teb cua sov, vim hais tias cov kav dej ntau yog ntsia rau hauv pem teb ntawm txhua qhov project, thiab cov kav dej yuav tsum muaj cov pa oxygen permeability tsawg heev, yog li cov pa nkag mus yuav tsis ua rau muaj kev puas tsuaj thiab tsis tsim nyog. Cov kav dej yas txheem tsis tuaj yeem ua tau raws li qhov xav tau ntawm cov pa oxygen permeability.

Khoom nta:
Muaj peb txoj hauv kev ntawm cov cua kub dissipation: conduction, convection thiab hluav taws xob. Qhov kev xaiv ntawm thermal kev nplij siab yog cuam tshuam los ntawm ntau yam xws li dav hlau thiab ntsug kub faib, cua ceev thiab tsim nyog tus nqi ntawm radiant tshav kub.
Thaum tshav kub kub conduction: Lub tshav kub nruab nrab nyob rau hauv lub radiator exchanges tshav kub nyob rau hauv lub radiator hloov lub tshav kub mus rau lub puab phab ntsa ntawm lub radiator. Cov phab ntsa sab hauv hloov cov cua sov mus rau sab nrauv phab ntsa los ntawm kev ua kom sov. Hlau feem ntau yog hluav taws xob; tooj liab-aluminium composite thiab aluminium alloy muaj ob qho tib si convection thiab hluav taws xob.
Radiant radiator: ib lub tshuab hluav taws xob uas siv hluav taws xob los ua lub hauv paus thiab siv cov convection ua ib txoj hauv kev ntxiv rau dissipate cua sov rau chav cua sov. Cov dej kub yuav tsum tau muaj. Kev faib hluav taws xob sab hauv tsev tsis sib npaug, thiab lub tshuab hluav taws xob nws tus kheej yog kub dua. Xws li cam khwb cia hlau radiator, cylindrical steel radiator, thiab lwm yam.
Convection radiator: Ib lub tshuab hluav taws xob uas ua kom cua sov ib puag ncig tag nrho lossis feem ntau yog los ntawm kev hloov pauv cua sov. Kev faib hluav taws xob sab hauv tsev tsis sib npaug, qhov kub thiab txias nce nrawm dua, thiab lub vaj huam sib luag tsis xav tias kub rau qhov kov.
