NangonaI-PVCyeyona mbhobho ixhaphakileyo engeyoyesinyithi ehlabathini, i-PPR (iPolypropylene Random Copolymer) yeyona mbhobho iqhelekileyo kwezinye iindawo ezininzi zehlabathi. I-PPR joint ayisiyo-PVC cement, kodwa ifudunyezwa sisixhobo esikhethekileyo sokudibanisa kwaye ngokusisiseko inyibilike ibe yimbumba iyonke. Ukuba yenziwe ngokuchanekileyo ngezixhobo ezifanelekileyo, i-PPR joint ayisoze ivuze.

Fudumeza isixhobo sokudibanisa kwaye ulungiselele umbhobho

Beka isokhethi yobukhulu obufanelekileyo kwisixhobo sokudibanisa. Uninzi lwazoI-PPRIzixhobo zokuwelda ziza neepayara zeesokhethi zesilisa nezesifazana ezinobukhulu obahlukeneyo, ezihambelana nobubanzi obuqhelekileyo bepayipi ye-PPR. Ke ngoko, ukuba usebenzisa ipayipi ye-PPR enobubanzi obuyi-50 mm (ii-intshi eziyi-2.0), khetha ipayara yemikhono ephawulwe ngama-50 mm.

Izixhobo zokudibanisa eziphathwa ngesandla zihlala zikwazi ukusingathaI-PPRimibhobho ukusuka kwi-16 ukuya kwi-63 mm (0.63 ukuya kwi-2.48 intshi), ngelixa iimodeli zebhentshi zinokuphatha imibhobho ubuncinane eyi-110 mm (4.3 intshi).
Ungafumana iimodeli ezahlukeneyo zezixhobo ze-PPR fusion kwi-intanethi, ngamaxabiso aqala kwi-US$50 ukuya kwi-US$500.

Faka isixhobo sokudibanisa ukuze uqalise ukufudumeza isokhethi. Uninzi lwezixhobo zokudibanisa ziya kuxhunywa kwisokhethi eqhelekileyo ye-110v. Esi sixhobo siza kuqala ukufudumeza ngoko nangoko, okanye kusenokufuneka uvule iswitshi yombane. Iimodeli ziyahluka, kodwa kungathatha imizuzu embalwa ukuba isixhobo sifudumeze isokhethi kubushushu obufunekayo. [3]
Lumka kakhulu xa usebenzisa isixhobo sokudibanisa ubushushu kwaye uqinisekise ukuba wonke umntu kuloo ndawo uyazi ukuba siyasebenza kwaye sishushu. Ubushushu besokethi budlula ama-250 °C (482 °F) kwaye bunokubangela ukutsha okukhulu.

Sika umbhobho ube nobude obude ngokusika okugudileyo nokucocekileyo. Xa isixhobo sokudibanisa sishushu, sebenzisa isixhobo esisebenzayo ukuphawula nokusika umbhobho ube nobude obufunekayo ukuze ufumane ukusika okucocekileyo okuthe nkqo kwi-shaft. Iiseti ezininzi zezixhobo zokudibanisa zixhotyiswe ngezixhobo zokusika iipayipi ezibangela ukuba kube nzima okanye eziqinisayo. Xa zisetyenziswa ngokwemiyalelo, ezi ziya kuvelisa ukusika okugudileyo nokulinganayo kwi-PPR, okufanelekileyo kakhulu kwi-fusion welding. [4]
Imibhobho ye-PPR ingasikwa ngeesarha ezahlukeneyo zesandla okanye iisarha zombane okanye ii-wheeled pipe cutters. Nangona kunjalo, qiniseka ukuba isikwe sigudile kwaye silingana kangangoko, kwaye sebenzisa iphepha elincinci lesanti ukususa zonke ii-burrs.

Coca izinto zePPR ngelaphu kunye nesicoci esicetyiswayo. Isixhobo sakho sokudibanisa singacebisa okanye siquke isicoci esithile sepayipi yePPR. Landela imiyalelo yokusebenzisa esi sicoci ngaphandle kombhobho nangaphakathi kwezinto eziza kudityaniswa. Vumela iziqwenga zome okwethutyana. [5]
Ukuba awazi ukuba loluphi uhlobo lwesicoci omele ulusebenzise, ​​nceda unxibelelane nomenzi wesixhobo sokudibanisa.

Phawula ubunzulu bokuwelda ekupheleni koqhagamshelo lombhobho. Iseti yakho yezixhobo zokudibanisa isenokuza netemplate yokuphawula ubunzulu bokuwelda obufanelekileyo kwimibhobho ye-PPR enobubanzi obahlukeneyo. Sebenzisa ipensile ukuphawula umbhobho ngokufanelekileyo.
Okanye, ungafaka iteyipu yokulinganisa kwi-fitting oyisebenzisayo (njenge-90-degree elbow fitting) ide ifikelele kwi-ridge encinci kwi-fitting. Thabatha i-1 mm (0.039 intshi) kolu linganiselo lobunzulu uze uyiphawule njengobunzulu be-weld kumbhobho.

Qinisekisa ukuba isixhobo sokudibanisa sishushu ngokupheleleyo. Izixhobo ezininzi zokudibanisa zinesikrini esikuxelelayo xa isixhobo sishushu kwaye sikulungele. Ubushushu ekujoliswe kubo buhlala buyi-260 °C (500 °F).
Ukuba isixhobo sakho sokudibanisa asinaso isibonisi sobushushu, ungasebenzisa i-probe okanye i-infrared thermometer ukuze ufunde ubushushu obukwisokhethi.
Ungathenga neentonga zokubonisa ubushushu (umz. iTempilstik) kwiivenkile ezithengisa izinto zokuwelda. Khetha iintonga zomthi eziya kunyibilika kwi-260 °C (500 °F) uze ucinezele enye kwisokethi nganye.
