Dab tsi yog cov yam ntxwv ntawm PP-R yeeb nkab?
PP-R yeeb nkab ntxiv rau txoj yas hluav taws xob lub teeb nyhav, kev tiv thaiv corrosion, tsis muaj scaling, lub neej ntev thiab lwm yam ntxwv, tab sis kuj muaj cov nram qab no tseem ceeb nta:
1, tsis muaj kuab lom, kev noj qab haus huv. PP-R raw khoom siv roj carbon monoxide, hydrogen, tsis muaj teeb meem tshuaj phem muaj nyob, tsis yog rau dej kub thiab dej txias, kuj tuaj yeem siv rau cov dej ntshiab haus.
2, thermal rwb thaiv tsev. PP-R tube thermal conductivity ntawm 0.21w / mk, tsuas yog 1/200 ntawm cov hlau.
3, zoo dua kub cev. PP-R raj Vicat softening point 131.5 ℃. Qhov siab tshaj plaws kev khiav hauj lwm kub txog li 95 ℃, yuav tsum ua kom tau raws li cov khoom siv dej hauv tsev thiab cov kev tswj fais fab siv hauv kev siv cov dej kub dej.
4, lub neej ntev kev ua haujlwm PP-R yeeb nkab nyob hauv kev kub ua haujlwm ntawm 70 ℃, ua haujlwm siab (PN) 1.Xwmpuam, kev ua haujlwm txog li 50 xyoo; nyob rau hauv chav sov (20 ℃) kev pab cuam lub neej txog li 100 xyoo.
5, yooj yim rau nruab. PP-R muaj kev vuam vias zoo, yeeb nkab, yeeb nkab fittings siv tau kub yaj thiab fused txuas, installation yooj yim, txuas qhov txuas ntawm lub zog yog siab dua lub zog ntawm cov yeeb nkab nws tus kheej.
6, cov khoom yuav tuaj yeem siv tau. PP-R pov tseg tom qab tu tsev, tawg tom qab muab ub rau cov yeeb nkab, cov yeeb nkab tag. Tus nqi ntawm cov khoom siv rov qab tsis tshaj 10% ntawm tag nrho, tsis cuam tshuam cov khoom zoo.
