PEX EVOH Oxygen Barrier Pipe rau Underfloor cua sov

PEX yeeb nkab kho dua tshiab nrog EVOH txheej txheej muab cov pa oxygen zoo uas yuav luag tag nrho tiv thaiv cov pa oxygen permeation los ntawm cov yeeb nkab phab ntsa hauv lub neej. Ua kom puas oxygen tawm yog qhov tseem ceeb rau radiant cua sov system kev cia siab rau thiab kav ntev.

EVOH yog luv luv rau ethylene-vinyl cawv copolymer, thiab EVOH yog cov khoom siv dav siv ntau tshaj plaws, EVOH yog tus cwj pwm los ntawm cov pa phem zoo heev thiab kev ua haujlwm zoo heev, ntxiv rau cov pob tshab zoo, gloss, txhua yam muaj zog, scalability, hnav tsis kam, txias ua haujlwm. thiab lub zog nto.

Vim nws qhov kev ua tau zoo heev, EVOH tau siv dav hauv ntau lub lag luam. EVOH yog cov khoom siv tsis zoo rau ib puag ncig, hauv cov kev sib txuas tshwj xeeb, yuav tsis tsim cov tshuaj lom thiab tsis zoo, thiab tseem muaj cov khoom thaiv zoo heev, roj tsis kam, tshuaj tiv thaiv corrosion thiab pob tshab, nrog rau cov khoom muaj zog antistatic, yog li nws yog dav siv nyob rau hauv roj tso tsheb hlau luam, thiab huab cua barrier cov ntaub ntawv thiab lwm yam teb.

Qhov cuam tshuam zoo ntawm cov pa oxygen plays lub luag haujlwm tseem ceeb hauv lub voj voog dej hluav taws xob cua sov. Kev lag luam thiab cov dej hauv tsev muaj cov khoom siv xws li chlorides, minerals, thiab cov pa roj carbon dioxide uas cuam tshuam nrog cov hlau hauv cov kav dej, qhov twg cov kab thiab cov hlau muaj cov khoom siv hluav taws xob thiab tshuaj lom neeg uas maj mam ua rau tooj liab, txhuas, thiab txawm tias stainless hlau Cheebtsam. nyob rau hauv cov yeeb nkab systems, tshav kub exchangers, thiab manifold blocks ntawm sab hauv tawm. Cov khoom me me tab sis ntsuas tau los ntawm corrosion tuaj yeem khaws cia hauv cov dej thiab tso rau ntawm cov yeeb nkab phab ntsa, maj mam txo cov yeeb nkab ntws thiab cov cua sov hloov mus rau lub sijhawm, thaum cov kab mob thiab cov kab mob hauv cov yeeb nkab tsim ib txheej sedimentary ntawm cov yeeb nkab phab ntsa thiab maj mam harden, ua rau. nyob rau hauv ib tug nruam txo nyob rau hauv cov yeeb nkab puab txoj kab uas hla. Qhov xwm txheej no yuav ua rau kev ua haujlwm ntawm cov cua sov hauv pem teb txo qis heev. Feem ntau, peb yuav yaug hauv pem teb cua sov hluav taws xob hluav taws xob nrog dej los ntawm qee cov khoom siv ntxhua khaub ncaws, txawm hais tias feem ntau ntawm cov khoom muag muag tuaj yeem ntxuav tawm, txawm tias cov dej ntws tawm zoo li ntshiab tom qab cov yeeb nkab tau ntws tawm, tab sis cov sediment tseem txuas nrog. sab hauv ntawm cov yeeb nkab.

Kev tsim cov kav dej nrog cov txheej txheem oxygen barrier (EVOH) yog qhov nyuaj vim nws cuam tshuam seb cov yeeb nkab puas muaj 3 - lossis 5- txheej txheej. Feem ntau hais lus, 3- txheej txheej txheej ntawm cov pa thaiv lub raj, cov txheej txheem oxygen thaiv yuav raug coated nyob rau hauv txheej txheej ntawm cov yeeb nkab. Ntawm ib sab, raws li cov khoom siv ntawm cov txheej txheem oxygen thaiv, cov pa oxygen thaiv lub peev xwm ntawm cov resin no yuav raug txo qis heev tom qab raug cuam tshuam los ntawm qhov chaw ntub dej; Ntawm qhov tod tes, qhov hnyav ib puag ncig ntawm qhov chaw siv cua sov hauv pem teb los yog kev ua haujlwm ntawm kev rub thiab lwm yam yooj yim rau khawb qhov saum npoo ntawm cov yeeb nkab, kom nws tsis tuaj yeem ua tiav lub hom phiaj ntawm kev tiv thaiv oxygen. 5- txheej txheej txheej ntawm cov pa thaiv cov yeeb nkab, cov pa thaiv txheej txheej yog nyob rau hauv nruab nrab ntawm cov yeeb nkab, thiab kev siv cov txheej txheem co-extrusion molding, cov khoom yuav tsum tau ua ntawm cov khoom siv extrusion yog qhov siab, tag nrho cov nqi yog siab dua 3- txheej txheej ntawm cov pa thaiv cov yeeb nkab. Txhawm rau txo qhov tsis zoo ntawm cov pa oxygen permeability ntawm tag nrho cov hluav taws xob hluav taws xob, nws raug nquahu kom siv 5 txheej ntawm PEX-EVOH thaum pib.
