Ukuthengiswa komkhiqizi wamapayipi amanzi e-polyethylene
I-epoxy yangaphandle ye-polyethylene ipayipi yensimbi evimbela ukubola iwuhlobo olusha lwepayipi lensimbi eliyinhlanganisela yepulasitiki. Yakhiwe nge-substrate yepayipi lensimbi, i-epoxy resin yangaphakathi yokugqoka kanye ne-polyethylene yangaphandle yokugqoka. Inezici ezinhle kakhulu zemishini, ukumelana nokugqwala kanye nokumelana nokuguga. Isetshenziswa kakhulu endaweni yokongiwa kwamanzi, amandla kagesi, imboni yamakhemikhali, i-petroleum nezinye izimboni eziningi.
Ipayipi lensimbi le-polyethylene elingaphakathi le-polyethylene evimbela ukubola elingaphakathi lihlukaniswe laba: ukuhlangana kwangaphakathi okuboshwe i-epoxy powder yangaphandle ye-polyethylene evimbela ukubola kwepayipi, uketshezi lwangaphakathi lwe-epoxy powder lwangaphakathi olulodwa ungqimba lwe-polyethylene ipayipi lensimbi evimbela ukubola, ukuhlangana kwangaphakathi okuboshwe i-epoxy powder ngaphandle kwemigqa emithathu ye-polyethyle I-3PE) ipayipi lensimbi elivimbela ukubola, i-epoxy ewuketshezi yangaphakathi (ipn8710) ipayipi lensimbi elinezingqimba ezintathu le-polyethylene elivimbela ukubola
Ukwakheka kwesakhiwo se-epoxide yangaphakathi kanye ne-polyethylene ye-monolayer yangaphandle
1. Izinto eziyisisekelo zamapayipi ensimbi: ipayipi lensimbi elingenamthungo, ipayipi lensimbi elishiselwe kagesi (i-weld eqondile, i-spiral weld)
2. I-internal anti-corrosion coating: ukuhlanganiswa kwe-sanitary bonded epoxy powder coating, i-heavy-duty anti-corrosion fusion ehlanganiswe ne-epoxy resin powder.
Umdwebo wesakhiwo we-polyethylene yongqimba olulodwa yangaphandle

3. I-anti-corrosion coating yangaphandle: i-hot melt-layer polyethylene powder coating
I-epoxide yangaphakathi yangaphandle ye-polyethylene (3PE) enezingqimba ezintathu
1. Izinto eziyisisekelo zamapayipi ensimbi: ipayipi lensimbi elingenamthungo, ipayipi lensimbi elishiselwe kagesi (i-weld eqondile, i-spiral weld)
2. I-internal anti-corrosion coating: ukuhlanganiswa kwe-sanitary bonded epoxy powder coating, i-heavy-duty anti-corrosion fusion ehlanganiswe ne-epoxy resin powder.
3.I-anti-corrosion coating yangaphandle: i-hot melt ye-polyethylene enamathelayo. Ungqimba olungezansi luyimpushana ehlanganisiwe ye-epoxy resin, ungqimba oluphakathi luyi-adhesive encibilikayo eshisayo, kanti ungqimba olungaphandle luyi-polyethylene enokuminyana okuphezulu.
Ukuqhathaniswa phakathi kwe-epoxide yangaphandle ye-monolayer PE kanye ne-epoxide yangaphakathi yangaphandle 3PE
I-polyethylene ne-epoxy inokumelana nokugqwala okuhle kakhulu, kepha ngayinye inezinzuzo zayo. I-Polyethylene iyimpahla ye-thermoplastic enokuguquguquka okuhle nokumelana nama-bump. Ngenxa yama-molecule angewona ama-polar, ukuphikelela kokunamathela phakathi kwe-polyethylene nepayipi yensimbi kumpofu; I-Epoxy resin iyi-molecule ye-polar enamaqembu e-hydroxyl. Emazingeni okushisa athile, kulula ukusabela ngamapayipi ensimbi futhi inokunamathela okuqinile. Kodwa-ke, ayimelani nokungqubuzana ngoba iyinto ebeka i-thermosetting. Ngakho-ke, ukuhlanganiswa kwezinto ezimbili kungokwenhlanganisela engcono kakhulu embonini ye-anti-corrosion.
Imboni yamapayipi ensimbi ahlanganiswe ngepulasitiki yathuthukiswa kusukela ekuqaleni kwe-polyethylene yangaphakathi nangaphandle kuya epoxy yangaphakathi nangaphandle ngenxa yezinkinga zokunamathela, kodwa ungqimba lwe-epoxy lwangaphandle alumelani nokungqubuzana. Kamuva, yathuthukela esizukulwaneni sesithathu i-polyethylene yangaphakathi ye-epoxy yangaphandle, kodwa inkinga yokunamathela isekhona lapho i-polyethylene yongqimba olulodwa ihlanganiswa ngokuqondile nepayipi lensimbi. Ekugcineni, yathuthukela esizukulwaneni sesine sokulwa nokugqwala kwangaphakathi kwe-epoxy yangaphandle enezingqimba ezintathu ze-polyethylene yesakhiwo.
