Iintengiso zemibhobho yamanzi yePolyethylene
I-epoxy yangaphakathi yangaphandle ye-polyethylene umbhobho wensimbi wokuchasana luhlobo olutsha lwentsimbi yentsimbi yombhobho oyintlanganisela. Iqulethwe nge-substrate yombhobho wensimbi, i-epoxy resin yangaphakathi yokwaleka kunye ne-polyethylene yangaphandle yokugqoka. Ineempawu ezigqwesileyo zoomatshini, ukuxhathisa ukubola kunye nokumelana nokuguga. Isetyenziswa kakhulu kugcino lwamanzi, amandla ombane, ishishini lemichiza, i-petroleum kunye namanye amashishini amaninzi.
Umbhobho wentsimbi we-epoxy ongaphandle we-polyethylene ongaphandle wahlulwe waba: udibaniso lwangaphakathi oludityaniswe yi-epoxy ngumgubo wangaphandle umaleko omnye we-polyethylene umbhobho wentsimbi wokuchasa umbhobho, ulwelo lwangaphakathi lwe-epoxy umgubo wangaphakathi we-polyethylene umbhobho wentsimbi wokuchasa umbhobho, udibaniso lwangaphakathi oludityaniswe ne-epoxy umgubo ongaphandle we-polyethyle I-3PE) umbhobho wentsimbi wokuchasa umbhobho, ulwelo lwangaphakathi epoxy (ipn8710) umbhobho wentsimbi wangaphandle onemigangatho emithathu yepolyethilini
Ukubunjwa kwesakhiwo se-epoxide yangaphakathi kunye ne-polyethylene ye-monolayer yangaphandle
1. Isiseko sombhobho wentsimbi: umbhobho wentsimbi ongenamthungo, umbhobho wentsimbi odityanisiweyo wombane (i-weld ethe tye, i-spiral weld)
2. I-anti-corrosion yangaphakathi yokugquma: i-sanitary fusion edibeneyo ye-epoxy powder yokugqoka, i-heavy-duty anti-corrosion fusion edibeneyo epoxy resin powder.
Umzobo wesakhiwo se-polyethylene yangaphandle eyodwa
Umzobo wesakhiwo se-polyethylene yangaphandle eyodwa
3. I-anti-corrosion coating yangaphandle: i-hot melt i-polyethylene powder coating enye
I-epoxide yangaphakathi yangaphandle ye-polyethylene (3PE) yangaphandle
1. Isiseko sombhobho wentsimbi: umbhobho wentsimbi ongenamthungo, umbhobho wentsimbi odityanisiweyo wombane (i-weld ethe tye, i-spiral weld)
2. I-anti-corrosion yangaphakathi yokugquma: i-sanitary fusion edibeneyo ye-epoxy powder yokugqoka, i-heavy-duty anti-corrosion fusion edibeneyo epoxy resin powder.
3.I-anti-corrosion coating yangaphandle: i-hot melt i-polyethylene eshushu yokwaleka. Umaleko ongezantsi yi-fusion edityaniswe ne-epoxy resin powder, umaleko ophakathi yi-adhesive eshushu enyibilikayo, kwaye owona maleko ungaphandle yi-high-density polyethylene.
Ukuthelekisa phakathi kwe-epoxide yangaphandle ye-monolayer PE kunye ne-epoxide yangaphakathi yangaphandle ye-3PE
I-Polyethylene kunye ne-epoxy zinokumelana ne-corrosion, kodwa nganye ineenzuzo zayo. I-Polyethylene yimathiriyeli ye-thermoplastic enokuguquguquka okulungileyo kunye nokuchasana kwe-bump. Ngenxa yeamolekyu ezingezizo ze-polar, ukunyamezela kokubambelela phakathi kwe-polyethylene kunye nombhobho wensimbi kubi; I-epoxy resin yimolekyuli yepolar enamaqela e-hydroxyl. Kwiqondo lokushisa elithile, kulula ukusabela kunye nemibhobho yensimbi kwaye inokubambelela ngokuqinileyo. Nangona kunjalo, ayixhathisi xa ingqubana kuba iyinto ebeka thermosetting. Ke ngoko, ukudityaniswa kwezi zinto zimbini zezona zinto zilungileyo kwishishini lokulwa nomhlwa.
Ishishini lombhobho wentsimbi efakwe kwiplastiki yaphuhliswa ukusuka kwi-polyethylene yangaphakathi nangaphandle ukuya kwi-epoxy yangaphakathi nangaphandle ngenxa yeengxaki zokubambelela, kodwa i-epoxy layer yangaphandle ayixhathisi ukungqubana. Kamva, yaphuhliswa kwisizukulwana sesithathu se-epoxy yangaphandle ye-polyethylene yangaphandle, kodwa ingxaki yokubambelela isekhona xa i-polyethylene yomgca omnye idibaniswa ngokuthe ngqo kunye nombhobho wensimbi. Ekugqibeleni, yaphuculwa ukuya kwisizukulwana sesine sokuchasana nokubola kwangaphakathi kwe-epoxy yangaphandle ene-polyethylene yolwakhiwo lwangaphandle.
