Umbhobho wesinyithi womelele, kulula ukusebenza ngawo kwaye awubizi, kodwa kwanolwelo olunoburharha obuncinci lunokuwutya ngokukhawuleza, ukusuka ngaphakathi nangaphandle, lunciphisa ngokuqatha ubomi bawo.Imibhobho ye-nonmetallic, i-fiberglass kunye ne-thermoplastics, ayinawo amandla omzimba wemibhobho yesinyithi, kodwa inokumelana okugqwesileyo kweekhemikhali.Imibhobho yeplastiki enemigca idibanisa ezona zixokelelwano zombhobho eziqhelekileyo zibe nye.
Iinkqubo zeplastiki ezinemibhobho yeplastiki zibonelela ngokuxhathisa kweekhemikhali zeplastiki kunye nokomelela okungokwemvelo kwentsimbi, okanye iinkqubo zemibhobho yentsimbi yealloyi.Oku kuhle kakhulu ekuphatheni iiasidi, izinto ezidliwayo kunye nezinto ezinobungozi.Umbhobho owenziwe ngeplastiki unokwenziwa kunye nokuba ukhululekile okanye uvalelwe kwi-liner, nangona kunjalo, umgca ovalelweyo unciphisa umphumo wokwahlukana kwe-coefficient yokwandisa phakathi kwentsimbi kunye nomgca.
Kukho ulwazi oluninzi olungelulo kwindawo yemarike malungaPTFE umbhobho onemigca.Indlela abanye abavelisi bemibhobho enemigca yeplastiki abenza ngayo ukhokelelwa ekubeni ukholelwe ukuba sisisombululo kuzo zonke iimfuno zakho zemibhobho eyenziwe ngeplastiki kwaye iya kusingatha zonke iimeko zenkonzo ukusuka kobulali ukuya kwingozi.Asiyonyaniso leyo.Iinkqubo zemibhobho ye-PTFE ziqhelene neengxaki ezininzi ezibalulekileyo:
1. I-PTFE intambo yombhobho kunye ne-PTFE ifake i-lined fittings kufuneka ikhutshwe ngokuhambelana nenkcazo ye-ASTM yepayipi yeplastiki kunye nezixhobo zeplastiki, i-F-1545.I-PTFE yeyona fluoropolymer ingenekayo esidibana nayo kwaye ngenxa yokuba iphuma umoya, yonke into egqobhozayo kwi-liner ikhutshelwa emoyeni.
2. I-PTFE ineepropati zomatshini ezihluphekayo kuyo nayiphi na i-fluoropolymer esihambelana nayo.Amalungu akwi-PTFE ahlala echatshazelwa kukuhamba kunye nokuhamba okubandayo njengoko kuchaziwe kwikhonkco leendaba ezishushu ezingezantsi.Amalungu aqinileyo abalulekile kwimfezeko yenkqubo yemibhobho eneplastiki.Ekuphela kwento embi kunokukhuphela imveliso yakho emoyeni kukuyilahla kubasebenzi, emhlabeni, okanye kwisixhobo ngelungu elivuzayo.
3. I-PTFE yeyona intlaka ye-fluoropolymer exabisa kancinane esetyenziswa kumbhobho owenziwe ngeplastiki kunye nofakelo lweplastiki.I-15 ukuya kwi-20% yeendleko zezinye i-fluoropolymer resins.Ukurhweba kukuba uyeka ukuxhathisa okugqwesileyo kokungena kunye neepropathi zoomatshini ukuze wonge imali.Iinkqubo zombhobho wePlasitiki zidla ngokusetyenziswa ukuthwala iikhemikhali eziyingozi neziyingozi empilweni.
