Qhov sib txawv ntawm PPR yeeb nkab thiab PVC yeeb nkab yog raws li nram no. Xim txawv: Cov khoom siv ntawm PPR raj muaj qhov tawv, thiab xim zoo nkauj yog ci, thiab lwm yam yog lub teeb daj daj, thiab xim tsis zoo yog qhov tsis meej pem. Cov yeeb nkab PVC yog mis nyuj dawb, cov khoom siv yog ib qho nyuaj thiab nkig, thiab ntu ntu tsis ci, tab sis nws cov tsos yog ci iab. Qhov sib txawv ntawm phab ntsa thickness: Qhov diameters ntawm PPR thiab PVC kav yog tib yam, qhov sib txawv loj tshaj plaws yog lub thickness ntawm cov yeeb nkab phab ntsa, lub thickness ntawm cov yeeb nkab PPR, thiab nyias phab ntsa ntawm cov yeeb nkab PVC. Muaj kev ntaus ntawv ntawm PPR yeeb nkab thiab PVC yeeb nkab. Lub toughness ntawm PPR yeeb nkab yog zoo, thiab phab ntsa ntawm PPR yeeb nkab yog thicker nyob rau hauv tib txoj kab uas hla. PPR yeeb nkab muaj qhov zoo ntawm lub teeb yuag, zoo corrosion kuj, tsis muaj fouling, thiab lub neej ua haujlwm ntev. Ntxiv mus, PPR yeeb nkab muaj kev nyab xeeb thiab tsis muaj tshuaj lom, thiab tuaj yeem siv rau hauv cov kav dej kub thiab txias, nrog rau hauv cov dej haus. Qhov kub siab tshaj plaws ntawm PPR raj tuaj yeem ua haujlwm ntawm 90 degrees, thiab lub neej kev pabcuam tuaj yeem ua tau ntau tshaj 50 xyoo ntawm 70 degrees, thiab nyob rau hauv chav tsev kub, nws lub neej kev pab yog ntau tshaj 100 xyoo. Lub installation ntawm PPR yeeb nkab yog yooj yim heev, vim hais tias PPR muaj kev vuam zoo, txawm tias nws yog thermal vuam lossis hluav taws xob vuam tshuab, nws yooj yim heev. Cov khoom tawg ntawm PPR yeeb nkab tuaj yeem rov ua dua tshiab, thiab nws kuj tseem tuaj yeem siv rau kev siv thib ob hauv kev tsim cov kav dej thiab cov yeeb nkab fittings, thaum PVC yeeb nkab tsis tuaj yeem siv rau kev siv thib ob.
