PPR yeeb nkab yog ib tug ncaj, nruj cylindrical yeeb nkab ua los ntawm polypropylene random copolymer yas thiab ua los ntawm ib tug nruam extrusion txheej txheem. Lawv feem ntau yog ntsuab los yog xim dawb thiab txawv nyob rau hauv sab nraud txoj kab uas hla loj ntawm 20 hli mus rau 110 hli, ua rau cov yeeb nkab phab ntsa ntau thicker dua PVC. PPR kav dej tuaj nrog ntau yam fittings, qhov chaw thiab accessories rau ntau yam ntawm cov yeeb nkab diameters.
PPR yeeb nkab nta
Tsawg thermal conductivity
PPR muaj cov thermal conductivity tsawg, uas txhais tau hais tias qhov kub thiab txias tsis yooj yim hloov los ntawm ib puag ncig sab nraud mus rau cov kua hauv cov yeeb nkab, thiab lwm yam. Qhov zoo tshaj plaws no txo cov cua sov los yog kub nce thaum lub sij hawm hloov cov kua dej kub los yog txias, feem, ua rau lub zog txuag hluav taws xob thiab txo cov nqi rwb thaiv tsev rau cov kav dej PPR.
Lub neej ntev thiab ruaj khov
PPR piping systems tseem ua haujlwm rau ntau tshaj 50 xyoo thoob plaws ntau yam ntawm cov kua thiab ambient kub. Tsis tas li ntawd, cov kav dej PPR muaj qhov ua tau zoo nyob rau hauv ob qho tib si dej kub thiab dej txias. Ua ntej, nws tuaj yeem tiv taus qhov kub thiab txias ntawm cov dej kub.
Nyob rau tib lub sijhawm, tsis zoo li lwm hom yeeb nkab yas, PPR yeeb nkab muaj peev xwm tiv taus qhov cuam tshuam yam tsis muaj kev pheej hmoo ntawm kev tawg lossis tawg, txawm tias huab cua txias.
Ua haujlwm sab hauv
Piv nrog rau cov kav dej ib txwm muaj, sab hauv ntawm cov kav dej PPR yog du heev thiab kev sib txhuam coefficient tsawg heev. Qhov no txo qis kev poob siab thaum lub sij hawm hloov cov dej thiab kev faib tawm, ntxiv dag zog rau lub zog ntawm PPR piping systems. Tsis tas li ntawd, tsis zoo li cov kav hlau, PPR yuav tsis tev lossis nplai, ua rau nws muaj kev nyab xeeb dua.
Tshuaj thiab mechanical durability
PPR muaj qhov ua tau zoo heev rau kev puas tsuaj los ntawm cov khoom tawv tawv piv rau cov kav dej yas. Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog nyob rau hauv cov dej zoo los yog cov ntawv thov kev lag luam uas cov kua xa tawm tuaj yeem muaj cov khoom abrasive.
Tsis tas li ntawd, tsis zoo li cov kav hlau ib txwm siv, PPR yog inert rau feem ntau cov electrolytes thiab tshuaj nyob rau hauv ntau qhov kub thiab txias. Qhov no electrolytic thiab chemical inertness tso cai rau PPR yeeb nkab siv yam xyuam xim nyob rau hauv cov xwm txheej uas muaj dej salinity siab (piv txwv li, nyob rau hauv lub pas dej ua ke daim ntaub ntawv siv dej hiav txwv) los yog txawm heev corrosive tshuaj (piv txwv li, nyob rau hauv industrial daim ntaub ntawv).
Ecological thiab economic efficiency
Vim tias cov kav dej PPR yog qhov hnyav, lawv txoj kev thauj mus los, kev tuav thiab kev teeb tsa tsis tas yuav siv zog ntau lossis ua haujlwm lub cev. Nyob rau tib lub sijhawm, lawv yooj yim heev rau kev txiav, txuas thiab siv, ua rau lawv muaj kev lag luam ruaj khov.
Tsis tas li ntawd, koom nrog PPR cov kav dej thiab fittings tsuas yog ua los ntawm cov cua sov thiab tsis tas yuav muaj tshuaj ntxiv lossis cov khoom siv ntxiv. Tag nrho cov xwm txheej no pab PPR txo kev cuam tshuam ib puag ncig thiab nqi siv.
Daim ntawv thov PPR yeeb nkab
Kev ua haujlwm ntev, kev pheej yig thiab kev nyab xeeb zoo ntawm PPR tau ua rau nws siv ntau hom kev siv hauv xyoo tas los no.
Cov ntawv thov PPR yeeb nkab feem ntau suav nrog:
Cov kav dej kub thiab dej txias hauv cov tsev nyob, kev lag luam thiab cov chaw pej xeem. Cov kav dej muaj siv los thauj dej, dej huv, kua zaub mov, compressed cua thiab tshuaj corrosive. Muaj zog acidic los yog alkaline daws. Lub hauv paus radiator ntawm lub tsev heats dej, feem ntau teem nyob rau hauv lub voj voog kav.
