Yog lawm, kev tiv thaiv UV yog qhov tseem ceeb
PEX EVOH Tubeyuav tsum muaj kev tiv thaiv los ntawm UV teeb thaum lub sij hawm cia. PEX txheej txheej degrades los ntawm tshav ntuj. EVOH txheej tsis muab kev tiv thaiv nto. Piv txwv: UV puas ua rau cov yeeb nkab nkig thiab tsis muaj zog.
Yuav ua li cas UV ua rau PEX
UV hluav taws xob rhuav tshem PEX polymer chains. Qhov saum npoo yuav nkig thiab tawg. Qhov no ua rau cov yeeb nkab tsis muaj zog.PEX EVOH Tubepoob lub zog thaum raug UV.
EVOH txheej tsis pab
EVOH nyob rau hauv cov yeeb nkab qauv. Nws tsis tiv thaiv PEX txheej txheej. UV tsuas cuam tshuam rau sab nrauv.PEX EVOH Tubetsis muaj UV tiv thaiv los ntawm nws cov khaubncaws sab nraud povtseg.
Maximum raug UV
Feem ntau cov tuam txhab tso cai rau 12 lub hlis ntawm kev cia sab nraum zoov. Tsis tas li ntawd, cov yeeb nkab yog cuam tshuam. Kev teeb tsa ncaj qha hauv tshav ntuj tsis tso cai.PEX EVOH Tubexav tau kev tiv thaiv tam sim ntawd.
Cov txheej txheem tiv thaiv UV
Khaws cov kav dej hauv tsev lossis hauv qab npog. Siv opaque npog rau sab nraum zoov cia. Khaws lawv deb ntawm qhov rais.PEX EVOH Tubeyuav tsum tau tiv thaiv los ntawm tshav ntuj.
Piv txwv li: kev cia khoom zoo hauv tsev rau khoom
Ib lub khw muag khoomPEX EVOH Tubenyob rau hauv ib lub tsev rau khoom. Cov kav dej nyob deb ntawm qhov rais. Qhov chaw cia yog npog thiab ntxoov ntxoo. Piv txwv li: nyab xeeb, ntev - khaws cia.
Piv txwv: kev cia sab nraum zoov tsis tsim nyog
Ib tus neeg cog lus khaws cov kav dej rau sab nraum lub hnub. Cov kav dej raug UV.PEX EVOH Tubedegrades los ntawm raug. Piv txwv li: cov kav dej ua nkig thiab siv tsis tau.
Cov txheej txheem khaws cia
Khaws cov kav dej hauv qhov chaw qhuav, ntxoov ntxoo. Khaws qhov kub ntawm 5 txog 40 degrees. Siv cov yeeb nkab hauv 12 lub hlis.PEX EVOH Tubexav tau kev khaws cia kom raug.
Tuav thaum lub installation
Tiv thaiv cov kav dej los ntawm UV thaum lub sijhawm teeb tsa. Npog lawv thaum tsis siv. Nruab lawv tam sim tom qab tshem cov npog.PEX EVOH Tubeyuav tsum tau saib xyuas thaum lub sij hawm installation.
Cov cim qhia txog kev puas tsuaj UV
Discoloration ntawm cov yeeb nkab nto. Kev tawg los yog brittleness. Poob lub zog thiab yooj.PEX EVOH TubeUV puas yog pom.
Ntev - lub sijhawm ua haujlwm sab nraum zoov
Yog tsis muaj kev tiv thaiv, sab nraum zoov lub neej luv luv. Nrog kev tiv thaiv, nws kav ntau xyoo lawm. Kev tiv thaiv yog yuav tsum tau siv sab nraum zoov.PEX EVOH Tubetuaj yeem ua haujlwm sab nraum zoov thaum muaj kev tiv thaiv.
Cov ntsiab lus khaws cia zaum kawg
PEX EVOH Tubeyuav tsum muaj kev tiv thaiv UV thaum khaws cia. Khaws sab hauv tsev lossis hauv qab opaque npog. Qhov siab tshaj plaws sab nraum zoov cia yog 12 lub hlis. UV ua rau PEX txheej txheej sab nrauv puas. EVOH txheej tsis pab. Kev khaws cia kom zoo ua kom ntev - ua haujlwm tau zoo.PEX EVOH Tubeyog txhim khu kev qha thaum khaws cia. Piv txwv li: tiv thaiv koj cov peev txheej nrog kev cia kom zoo.
