Njengoko abantu benikela ingqalelo ngakumbi nangakumbi ekukhuselweni kwendalo kunye nophuhliso oluzinzileyo, ukusetyenziswa kwemibhobho kumashishini ahlukeneyo kunye nemimandla kuye kwaba yinto eqhelekileyo.Nangona kunjalo, imibhobho ihlala ibekwe kwindawo enzima, efana nobushushu obuphezulu, uxinzelelo oluphezulu, kunye nemithombo yeendaba eyonakalisayo. umonakalo omkhulu kubo, okukhokelela kwiindleko eziphezulu zokugcinwa kunye, kwezinye iimeko, iingozi okanye iintlekele zokusingqongileyo.Ukoyisa le mingeni, imibhobho inokugqithwa ngeengubo zokukhusela ezifanaIingubo ze-3LPEkunye neengubo ze-FBE zokwandisa ukuxhathisa ukubola kunye nokuphucula ukuqina kwazo.
I-3LPE yokwaleka, oko kukuthi, i-polyethylene enemigangatho emithathu, yinkqubo yokwaleka ye-multi-layer equka i-fusion ebondwe i-epoxy (FBE) isiseko, i-adhesive layer kunye ne-polyethylene topcoat layer.Inkqubo yokugquma inokumelana nokugqwesa okugqwesileyo, ukomelela koomatshini kunye nokumelana nempembelelo, iyenza isetyenziswe ngokubanzi kuyoimibhobho yeoli negesi,imibhobho yamanzi kunye namanye amashishini apho imibhobho isesichengeni kwindawo enomhlwa.
Ukwaleka kwe-FBE, kwelinye icala, yinkqubo yokwaleka yengubo enye equka i-thermosetting epoxy powder coating esetyenziswa kumphezulu wombhobho.Inkqubo yokugquma ine-adhesion egqwesileyo, i-abrasion ephezulu kunye nokuchasana kwempembelelo kunye nokuchasana kakuhle kweekhemikhali, okwenza kube lula ukukhuselwa kwemibhobho kumashishini ahlukeneyo afana neoli kunye negesi, amanzi kunye nokuthutha.
Zombini i-3LPE yokugquma kunye ne-FBE yokugqoka isetyenziswa ngokubanzi kubunjineli bemibhobho ngenxa yeempawu zabo ezibalaseleyo zokukhusela.Nangona kunjalo, ububanzi besicelo sabo siyahluka ngokuxhomekeka kwimeko ethile ukuba umbhobho kufuneka uphathwe.
Kwimibhobho yeoli kunye negesi, i-3LPE yokwambathisa ikhethwa ngenxa yokuba inokuxhathisa isenzo sokubola kweoli kunye negesi, kunye nempembelelo kunye nokukhuhlana komhlaba ojikelezileyo.Ukongeza, iingubo ze-3LPE ziyakwazi ukuxhathisa ukuchithwa kwe-cathodic, oku kukwahlulwa kweengubo ezivela kwiindawo zetsimbi ngenxa ye-electrochemical reactions.Oku kubaluleke ngakumbi kwimibhobho ekhuselweyo ekudlekeni.
In imibhobho yamanzi, Ukugquma kwe-FBE kukhetho lokuqala kuba inokuthintela ngokufanelekileyo ukubunjwa kwe-biofilm kunye nokukhula kweebhaktheriya, ezinokungcolisa umgangatho wamanzi.Ukugquma kwe-FBE kukwafanelekile kwimibhobho ehambisa i-media abrasive, njengesanti, igrabile okanye udaka, ngenxa yokumelana kwayo okugqwesileyo.
Kumbhobho wezothutho, nokuba yi-3LPE yokwaleka okanye i-FBE yokugquma ingasetyenziswa ngokwemeko ethile yothutho.Ukuba lo mbhobho ubekwe kwindawo enomhlwa, efana nemekobume yaselwandle, i-3LPE iyathandeka ngenxa yokuba iyaxhathisa intshukumo eyonakalisayo yamanzi olwandle kunye nezinto eziphilayo zaselwandle.Ukuba umbhobho ubonakaliswe kumajelo e-abrasive afana neeminerali okanye i-ores, i-FBE yokugquma ikhethwa njengoko inokubonelela ukuchasana okungcono kunokugqoka i-3LPE.
Ukushwankathela, umda wokusetyenziswa kwe-3LPE yokwaleka kunye nokwaleka kwe-FBE kuyahluka ngokwemiqathango ethile.ubunjineli bombhobho.Iinkqubo ezimbini zokugquma zineenzuzo zazo kunye nokungonakali.Ukukhethwa kwenkqubo yokwambathisa kufuneka kuqwalaselwe ngokubanzi izinto ezahlukeneyo ezifana nobume bendawo ephakathi, ubushushu kunye noxinzelelo lombhobho, kunye nokusingqongileyo okungqongileyo.Ngophuhliso oluqhubekayo lobugcisa bombhobho, sikholelwa ukuba kuya kubakho iinkqubo zokugubungela ezintsha kunye nezisebenzayo ukuhlangabezana neemfuno ezikhulayo zokukhuselwa kwemibhobho kunye nokhuseleko.
Sine-factory anti-corrossion enokwenza i-3PE yokugqoka, i-epoxy coating etc.Ukuba nawuphi na umbuzo nceda uqhagamshelane nathi.
