Yuav kom ua tau raws li cov neeg siv khoom xav tau, peb cov haujlwm txhua yam raug ua raws li peb lub ntsiab lus "Zoo Tshaj, Nqe Sib Tw, Kev Pabcuam Sai" rauppr nres valve, Ua cov kev daws teeb meem saum toj kawg nkaus ntawm peb lub Hoobkas, peb cov kev daws teeb meem tau raug sim thiab yeej peb cov ntawv pov thawj kev paub dhau los. Yog xav paub ntxiv txog cov kev ntsuas thiab cov npe khoom, nco ntsoov nias lub pob kom tau txais cov ntaub ntawv ntxiv.

Cov kav dej PPR

Piv rau cov kav hlau, cov kav PPR muaj qhov zoo ntawm kev yooj yim dua rau kev teeb tsa, kev rwb thaiv tsev zoo dua, thiab kev tiv taus xeb. Nws yog cov khoom siv dej haus zoo dua thiab zoo rau ib puag ncig thiab tseem yog cov khoom siv dej haus tseem ceeb hauv kev ua lag luam. Cov kav PPR feem ntau muaj cov xim hauv qab no, dawb, grey, ntsuab thiab curry, vim li cas qhov sib txawv no feem ntau yog vim muaj cov xim masterbatches sib txawv ntxiv.

Ntxiv rau cov yam ntxwv ntawm cov kav dej yas dav dav xws li lub teeb yuag, tiv taus corrosion, tsis scaling, thiab lub neej ntev, PP-R kav dej kuj muaj cov yam ntxwv tseem ceeb hauv qab no:

1 Tsis muaj tshuaj lom thiab huv.
Cov khoom siv raw ntawm PP-R tsuas yog cov pa roj carbon thiab hydrogen xwb, thiab tsis muaj cov khoom phom sij thiab lom. Nws huv si thiab txhim khu kev qha. Nws tsis yog tsuas yog siv rau cov kav dej txias thiab dej kub xwb, tab sis kuj siv rau cov dej haus huv.

2 Kev txuag cua sov thiab txuag hluav taws xob.
Lub thermal conductivity ntawm PP-R yeeb nkab yog 0.21w / mk, uas tsuas yog 1/200 ntawm cov yeeb nkab hlau.

3 Zoo dua kub tsis kam.
Lub Vicat softening point ntawm PP-R yeeb nkab yog 131.5 ℃. Qhov kub siab tshaj plaws ua haujlwm tuaj yeem ncav cuag 95 ℃, uas tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm lub tshuab dej kub hauv cov cai dej thiab dej ntws hauv tsev.

4 Lub neej ua haujlwm ntev.
Nyob rau hauv cov xwm txheej ntawm qhov kub ua haujlwm ntawm 70 ℃ thiab kev ua haujlwm siab (PN) ntawm 1.0MPa, lub neej ua haujlwm ntawm PP-R yeeb nkab tuaj yeem ncav cuag ntau dua 50 xyoo (muab tias cov khoom siv yeeb nkab yuav tsum yog S3.2 thiab S2.5 series lossis ntau dua); nyob rau hauv qhov kub ib txwm (20 ℃) ​​Lub neej ua haujlwm tuaj yeem ncav cuag ntau dua 100 xyoo.

5 Kev teeb tsa yooj yim thiab kev sib txuas txhim khu kev qha.
PP-R muaj kev ua haujlwm vuam zoo. Cov kav dej thiab cov khoom siv tuaj yeem txuas nrog los ntawm kev kub yaj thiab electrofusion. Kev teeb tsa yooj yim thiab cov pob qij txha txhim khu kev qha. Lub zog ntawm qhov sib koom ua ke ntau dua li lub zog ntawm cov yeeb nkab nws tus kheej.

6 Cov khoom siv tuaj yeem rov ua dua tshiab.
Cov khib nyiab PP-R raug ntxuav, tawg, thiab rov ua dua tshiab rau kev siv rau hauv kev tsim cov kav dej thiab cov khoom sib txuas. Cov khoom siv rov ua dua tshiab tsis pub tshaj 10% ntawm tag nrho cov khoom thiab tsis cuam tshuam rau qhov zoo ntawm cov khoom.
