PP-R Cov Khoom Siv Hluav Taws Xob yog tsim rau cov dej kub thiab dej txias
Kev piav qhia ntau lawm
● Kev nyab xeeb.PP-R cov ntaub ntawv muaj kev nyab xeeb, huv si thiab tsis muaj tshuaj lom
● Kev rwb thaiv tsev zoo.Thaum ua ntawv thov rau cov dej kub, tsis tas yuav tsum tau ntxiv cov ntaub ntawv rwb thaiv tsev, thiab qhov project nqi qis
● Corrosion kuj.Sab hauv phab ntsa ntawm cov kav dej yog du, cov dej ntws tsis kam yog me me, tsis scaling
● Kev ua haujlwm kub zoo heev.Kub-dej yeeb nkab thaum lub sij hawm ua hauj lwm kub yog 70 ℃, lub sij hawm luv luv kub tuaj yeem ncav cuag 95 ℃
● Kev tiv thaiv ib puag ncig ntawm ppr yeeb nkab: ppr yeeb nkab yog ib puag ncig zoo.Nws cov khoom siv raw molecules tsuas yog carbon thiab hydrogen ntsiab, thiab tsis muaj teeb meem thiab tshuaj lom.
● Thiab nws kuj yog kev tu cev heev.Nws tuaj yeem tsis tsuas yog siv los ua cov kav dej kub thiab dej txias, tab sis kuj yog cov dej haus huv.
● Thermal rwb thaiv tsev thiab lub zog txuag ntawm ppr yeeb nkab: Lub thermal conductivity ntawm ppr yeeb nkab yog 0.21w / mk, thiab qhov ratio ntawm steel yeeb nkab yog 1/200.Nws tuaj yeem pom tias nws cov thermal rwb thaiv tsev thiab lub zog txuag hluav taws xob zoo heev.
● PPR yeeb nkab muaj cov cua kub zoo: ppr yeeb nkab muaj cov cua kub zoo, nws cov Vicat softening point yog 131.5 ℃, nws siab tshaj
● Qhov kub thiab txias ua haujlwm tuaj yeem ncav cuag 95 ℃, uas tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov dej kub hauv lub tsev code.
● Lub neej ua haujlwm ntev ntawm ppr yeeb nkab: ppr yeeb nkab tuaj yeem ua haujlwm ntawm qhov kub ntawm 70 ℃, thiab nws lub neej kev pabcuam tuaj yeem ncav cuag ntau tshaj 50 xyoo.
● Muab piv nrog cov khoom siv, lub neej kev pabcuam tseem ntev dua.Yog tias nws ua haujlwm ntawm chav tsev kub ntawm 20 ℃, lub neej kev pabcuam tuaj yeem ncav cuag ntau tshaj 100 xyoo.
● Cov yeeb nkab ppr yog ib qho yooj yim rau nruab: vim hais tias cov yeeb nkab ppr muaj kev vuam zoo, cov yeeb nkab thiab cov yeeb nkab fittings tuaj yeem txuas nrog kub melting thiab hluav taws xob melting.
● Nws yooj yim heev rau nruab, thiab lub connector kuj tseem txhim khu kev qha.
Kev thov cheeb tsam
● Cov dej txias thiab dej kub;
● Cua sov system (xws li hauv pem teb thiab vaj huam sib luag cua sov thiab hluav taws xob cua sov system);
● Cov kav dej ntshiab huv;
●Central cua txias system;
● Tshuaj lom neeg cov kav dej kav dej;
● Lwm yam kev lag luam thiab kev ua liaj ua teb kav dej.
