NangonaI-PVCyeyona mbhobho ixhaphakileyo engeyiyo eyentsimbi emhlabeni, iPPR (iPolypropylene Random Copolymer) yimathiriyeli yombhobho esemgangathweni kwezinye iindawo ezininzi zehlabathi.Umdibaniso wePPR awuyiyo i-PVC yesamente, kodwa ifudunyezwa ngesixhobo esikhethekileyo sokudibanisa kwaye inyibilika ngokupheleleyo.Ukuba idalwe ngokuchanekileyo ngezixhobo ezifanelekileyo, i-PPR edibeneyo ayinakuze ivuze.

Fudumeza isixhobo sokudibanisa kwaye ulungiselele umbhobho

Beka ubungakanani obufanelekileyo kwisixhobo sokudibanisa.UninziPPRizixhobo ze-welding ziza kunye nezibini zesokethi zamadoda nabasetyhini ezinobungakanani obahlukeneyo, ezihambelana nobubanzi obuqhelekileyo bombhobho wePPR.Ngoko ke, ukuba usebenzisa umbhobho wePPR kunye nobubanzi be-50 mm (i-intshi ezi-2.0), khetha imikhono ebhalwe ngama-50 mm.

Izixhobo zokudibanisa ezibanjwa ngesandla ziyakwazi ukuphathaPPRimibhobho ukusuka kwi-16 ukuya kwi-63 mm (i-0.63 ukuya kwi-intshi ye-2.48), ngelixa iimodeli zebhentshi zinokuphatha imibhobho ubuncinane be-110 mm (i-intshi ezi-4.3).
Ungafumana iimodeli ezahlukeneyo zezixhobo zokudityaniswa kwePPR kwi-intanethi, ngamaxabiso aqala malunga ne-US$50 ukuya ngaphezulu kwe-US$500.

Faka isixhobo sokudibanisa ukuqalisa ukufudumeza isokhethi.Uninzi lwezixhobo zokudibanisa ziya kuplagi kwisokethi ye-110v eqhelekileyo.Isixhobo siya kuqalisa ukufudumeza kwangoko, okanye unokufuneka uvule iswitshi yamandla.Iimodeli ziyahluka, kodwa kunokuthatha imizuzu embalwa ukuba isixhobo sifudumeze isokhethi kwiqondo lobushushu elifunekayo.[3]
Lumka kakhulu xa usebenzisa isixhobo se-thermal fusion kwaye uqiniseke ukuba wonke umntu kwindawo uyazi ukuba iyasebenza kwaye ishushu.Iqondo lobushushu lesokethi lingaphezulu kwe-250 °C (482 °F) kwaye linokubangela ukutshisa okukhulu.

Nciphisa umbhobho ubude kunye ne-smooth, cut cut.Xa isixhobo sokuxuba sishushu, sebenzisa isixhobo esisebenzayo sokumakisha kwaye usike umbhobho ubude obufunekayo ukuze ufumane i-cut cut perpendicular to shaft.Uninzi lweeseti zezixhobo zokudibanisa zixhotyiswe nge-trigger okanye izisiki zemibhobho ebambezelayo.Xa zisetyenziswe ngokuhambelana nemiyalelo, ezi ziza kuvelisa i-smooth, i-uniform cut kwi-PPR, efanelekileyo kakhulu kwi-fusion welding.[4]
Imibhobho yePPR inokusikwa ngeesarha ezahlukeneyo zezandla okanye iisarha zombane okanye abasiki bemibhobho enamavili.Nangona kunjalo, qiniseka ukuba ukusikwa kugudileyo kwaye ngokusemandleni, kwaye sebenzisa i-sandpaper ecocekileyo ukususa zonke ii-burrs.

Coca amacandelo ePPR ngelaphu kunye nesicoci esicetyiswayo.Ikhithi yakho yesixhobo sokudibanisa inokucebisa okanye ibandakanye isicoci esithile se-PPR ityhubhu.Landela imiyalelo yokusebenzisa esi sicoci ngaphandle kombhobho kunye nangaphakathi kwezixhobo eziza kudibaniswa.Vumela amaqhekeza ome okwethutyana.[5]
Ukuba awuyazi ukuba loluphi uhlobo lwesicoci onokuthi usisebenzise, ​​nceda uqhagamshelane nomenzi wesixhobo sokudibanisa.

Phawula ubunzulu be-welding ekupheleni koqhagamshelwano lombhobho.Isixhobo sakho sokudibanisa singeza nethempleyithi yokumakisha ubunzulu be-weld obufanelekileyo kwimibhobho yePPR yeedayamitha ezahlukeneyo.Sebenzisa ipensile ukuphawula ityhubhu ngokufanelekileyo.
Kungenjalo, ungafaka iteyiphu yokulinganisa kwi-fitting oyisebenzisayo (efana ne-90-degree elbow fitting) ide ibethe i-ridge encinci kwi-fitting.Susa i-1 mm (0.039 intshi) kulo mlinganiso wobunzulu kwaye uyiphawule njengobunzulu be-weld kumbhobho.

Qinisekisa ukuba isixhobo sokudibanisa sifudunyezwe ngokupheleleyo.Izixhobo ezininzi zokudibanisa zinomboniso okuxelela xa isixhobo sifudunyezwa kwaye silungile.Iqondo lobushushu ekujoliswe kulo lidla ngokuba yi-260 °C (500 °F).
Ukuba isixhobo sakho sokudibanisa asinaso isibonisi sobushushu, ungasebenzisa iprobe okanye ithemometha ye-infrared ukufunda ubushushu kwisokethi.
Unako kwakhona ukuthenga iintonga zesalathisi sobushushu (umz. Tempilstik) kwiivenkile ezithengisa iintsimbi.Khetha izinti zomthi eziya kunyibilika kwi-260 °C (500 °F) kwaye uchukumise enye kwisokethi nganye.
