PPR kav (Polypropylene Random Copolymer) feem ntau yog koom nrog siv PPR fusion vuam txheej txheem. Txoj kev no suav nrog kev siv lub tshuab PPR fusion welding, uas ua kom sov qhov kawg ntawm cov kav dej thiab tom qab ntawd fuses ua ke nyob rau hauv siab.
Cov kauj ruam koom nrog hauv PPR fusion vuam txheej txheem yog raws li hauv qab no:
Kev npaj cov yeeb nkab
Ua ntej cov kav dej sib txuas, nws yog ib qho tseem ceeb uas yuav tsum tau ntxuav thiab npaj qhov kawg ntawm cov kav dej. Cov kauj ruam no suav nrog kev txiav cov kav dej kom ntev li ntev tau thiab xyuas kom meej tias qhov kawg huv si thiab tsis muaj av, plua plav, lossis khib nyiab.
Alignment ntawm Pipes
Cov kauj ruam tom ntej hauv kev sib koom ua ke PPR cov kav dej yog los kho lawv kom raug. Cov kav dej yuav tsum tau muab tso rau hauv lub tshuab fusion welding thiab muab tso rau qhov kawg uas yuav tsum tau koom ua ke yog sib ntsib.
Cua sov cov kav dej
Thaum cov kav dej raug ua kom raug, lub fusion vuam tshuab lub tshuab cua sov yog qhib, thiab cov kav dej tau muab tso rau qhov kub thiab txias. Cov txheej txheem cua sov yog qhov tseem ceeb los xyuas kom meej tias cov kav dej tuaj yeem sib txuas ua ke kom raug.
Fusion Vuam
Tom qab cov kav dej tau mus txog qhov kub thiab txias, cov khoom cua sov raug tshem tawm, thiab cov kav dej tau nrawm nrawm ua ke nyob rau hauv siab. Lub siab xyuas kom meej tias cov khoom melted los ntawm ob lub kav dej sib tov thiab fuse los tsim kom muaj kev sib koom ua ke.
Txias thiab teeb tsa
Cov kauj ruam kawg suav nrog tuav cov kav dej ua ke rau ob peb feeb kom tso cai rau kev sib koom ua ke kom txias thiab teeb. Cov txheej txheem no ua kom ntseeg tau tias qhov sib koom ua ke muaj zog, thiab cov kav dej tau ruaj khov ua ke. Tom qab qhov sib koom ua ke tau txias, txhua yam khoom siv ntau dhau tuaj yeem txiav tawm, thiab qhov sib koom ua ke yog npaj siv.
Nws yog ib qho tseem ceeb uas yuav tau ua raws li cov kauj ruam no kom ua tib zoo xyuas kom cov kav dej PPR sib koom ua ke muaj zog thiab tsis muaj paug. Nws kuj tseem pom zoo kom siv cov kav dej thiab fittings los ntawm tib lub chaw tsim khoom kom ntseeg tau tias muaj kev sib raug zoo thiab tiv thaiv txhua yam teeb meem nrog kev sib koom ua ke.
