PPR Txiv neej Socket

Yuav ua li cas weld PPR yeeb nkab?

1, kev tswj qhov kub thiab txias yuav tsum raug. PP-R kub yaj vuam kub yog: 253C -274 degree . Yog tias qhov ntsuas kub qis dua 253, cov yeeb nkab thiab cov yeeb nkab fittings tsuas yog ib txheej txheej nyias ntawm 00 melting, thaum lawv fused, lub zog ntawm fusion tsis tau lees paub, uas yog qhov peb feem ntau hu ua qhov tshwm sim ntawm Kev vuam tsis raug, hloov pauv, yog tias qhov kub siab tshaj 274 ° C, qhov chaw molecules ntawm cov yeeb nkab thiab cov yeeb nkab fittings raug puas ntsoog los ntawm qhov kub thiab txias, ua rau PP-R tsim cov kua nyias nyias, kev sib txuas yuav ua rau sab hauv ntawm cov yeeb nkab me me. , Qhov tseem ceeb tshaj, qhov txuas txuas yuav nkig thiab tawg, tshwj xeeb tshaj yog thaum cov kav dej tau ua tiav tag nrho thiab ua kom muaj zog nrog dej, cov teeb meem no feem ntau tshwm sim.
2, Lub sijhawm ntsuas kub tsis tu ncua yuav tsum ntev. Qhov ntev ntawm qhov ntsuas kub tsis tu ncua yog ib qho tseem ceeb ntawm kev ua haujlwm zoo lossis tsis zoo ntawm cov khoom siv vuam kub kub. Cov khoom siv kub yaj tseem muaj teeb meem ntawm kev siv cua sov tom qab cua sov mus txog qhov kub thiab txias, tshwj xeeb tshaj yog nyob rau lub caij ntuj no, lub qhov hluav taws xob cua, txawm tias nyob rau hauv qhov tsis ua hauj lwm sib txawv, nws cov cua sov siv kuj loj heev, thiab ib zaug ua haujlwm, nws cov kav dej thiab fittings yog siv cov cua sov sib cais, uas yuav tsum muaj lub zog thermal lub zog cia thiab lub sijhawm ua kom muaj peev xwm ntxiv ntawm cov khoom siv.
