Raws li kev soj ntsuam ntawm Tuam Tshoj lub koom haum tshawb fawb, qhib kev tsim kho kev lag luam yuav nce nyob rau hauv Suav teb thaum lub sij hawm, thiab qhov kev thov rau yeeb nkab cov ntaub ntawv yog tseem nce. Nyob rau hauv Suav teb, daim ntawv thov cov kav dej yas hauv ntau qhov chaw yog kev txhim kho kom zoo dua, thiab qhov kev thov rau cov kav dej yas yog tas li. Qhov tshiab ntawm cov khoom yeeb nkab yog ib txoj kev tsav tsheb loj heev rau cov yeeb nkab ua haujlwm.
Lub PPR raj tsis tsuas yog muaj cov yam ntxwv ntawm me nyhav, kev tiv thaiv kev ua kom tsis muaj zog, nyuaj scaling thiab ntev daim ntawv thov, tab sis kuj lwm yam nta xws li:
1. Cov cuab yeej luv luv thiab txuas nrog. PPR kuj muaj kev vuam voog zoo heev, uas muaj peev xwm yuav welded nrog kub yaj thiab hluav taws xob welding, thiab nws cov kev twb kev txuas muaj qee lub zog ntau tshaj li nws cov hardness.
2. PPR pov tseg tuaj yeem siv tau dua.
3. Nws daim ntawv thov sij hawm ntev ntev. PPR yeeb nkab hauv kev kub ua haujlwm 70 ℃, siab (PN) 1. OMPa mob, siv tau tsawg kawg 50 xyoo; Thaum muaj qhov ntsuas kub ntawm 20 ℃ tuaj yeem siv tsawg tshaj 100 xyoo.
4. PPR cov khoom siv muaj cov pa roj carbon thiab hydrogen cov ntsiab lus. Tsis muaj teeb meem thiab tshuaj lom nyob hauv lawv, uas yuav siv tau cov kav dej kub thiab dej kub thiab cov dej ntshiab huv.
5. Cov khoom no yuav raug thev tau thiab muaj zog. Lub thermal conductivity ntawm PPR raj yog 0.21w / mk, uas yog li 1/200 ntawm cov yeeb nkab steel.
Kev tiv thaiv tshav kub zoo heev. PPR yeeb nkab vicat softening point ntawm 131.5 ℃. Qhov kub siab tshaj plaws yog 95 ℃, tuaj yeem siv cov khoom siv dej kub hauv tsev tsim dej thiab kua txheem.
