Umbhobho ongenanto :
Umbhobho uthathwa ngokuba ungenanto ukuba awunayo isambatho esinamathele kuyo. Ngokuqhelekileyo, xa i-rolling igqityiwe kwi-mill yensimbi, izinto ezingenanto zithunyelwa kwindawo eyenzelwe ukukhusela okanye ukugqoka izinto eziphathekayo kunye nengubo efunwayo (egqitywe yimiqathango yomhlaba yendawo esetyenziswayo). Umbhobho ongenanto lolona hlobo luqhelekileyo lombhobho olusetyenziswa kwishishini lokupakisha kwaye luhlala lufakwa emhlabeni ukuze lusetyenziswe kwisakhiwo. Nangona kungekho zifundo zekhonkrithi ezibonisa ukuba umbhobho ongenanto uzinzile ngakumbi kunombhobho ogqunyiweyo wokufaka izicelo, umbhobho ongenanto uyinto eqhelekileyo kwishishini lolwakhiwo.
Umbhobho wokugalela :
I-galvanization okanye i-galvanization yenye yezona ntlobo zidume kakhulu zokugubungela umbhobho wensimbi. Nokuba intsimbi ngokwayo inenani leempawu ezigqwesileyo xa isiza ekuxhathiseni ukubola kunye nokuqina kokuqina, kufuneka idityaniswe ngakumbi nge-zinc ukuze igqitywe ngcono. Ukufakwa kwegalvanizing kunokwenziwa ngeendlela ezininzi, kuxhomekeke kubukho bendlela. Obona buchule budumileyo, nangona kunjalo, kukuntywila okushushu okanye i-batch dip galvanizing ebandakanya ukuntywiliselwa kombhobho wentsimbi kwibhafu ye-zinc etyhidiweyo. I-metallurgical reaction eyenziwa yi-alloy yentsimbi yombhobho kunye ne-zinc idala ukugqitywa kumphezulu wesinyithi obonelela ngomgangatho onganyangekiyo wokudusa ongazange ubekho kumbhobho ngaphambili. Enye inzuzo yegalvanizing ziinzuzo zeendleko. Njengoko inkqubo ilula kwaye ayifuni imisebenzi emininzi yesibini kunye ne-post-processing, ibe yindlela yokuzikhethela kubakhiqizi abaninzi kunye namashishini.
FBE - Fusion Bonded Epoxy Powder Coating Umbhobho :
Lo mbhobho wokugquma unika ukhuseleko olugqwesileyo kwimibhobho emincinci ukuya kwenkulu enobushushu obuphakathi (-30C ukuya kwi-100C). Ukusetyenziswa kwayo kudla ngokusetyenziswa kwioyile, igesi, okanye imibhobho yamanzi. I-adhesion egqwesileyo ivumela ukuxhathisa kwexesha elide kunye nokukhuselwa kombhobho. I-FBE ingasetyenziswa njengomaleko ombini obonelela ngeempawu zomzimba ezinamandla ezinciphisa umonakalo ngexesha lokuphatha, ukuthutha, ukufakela, kunye nokusebenza.
I-Single Layer Fusion Bonded Epoxy Umbhobho we-Anticorrosive: Umbane wamandla ombane;
I-Double Layer Fusion Bonded Epoxy Anticorrosive Pipe : Fistly bottom epoxy powder, and Then epoxy powder Surface.
3PE Epoxy Coating Umbhobho :
I-3PE Epoxy coated steel pipe ineengubo zomaleko ezi-3, i-FBE yokuqala yokwambathisa, umbindi ngumaleko oncamathelayo, ngaphandle umaleko we-polyethylene. Umbhobho wokugquma we-3PE yenye imveliso entsha ephuhliswe kwisiseko sokugquma kwe-FBE ukususela ngo-1980, equlethe izinto zokuncamathelisa kunye ne-PE (i-polyethylene). I-3PE inokomeleza iipropathi zemibhobho yomatshini, ukuxhathisa kombane okuphezulu, ukungangeni kwamanzi, ukunxiba, ukuchasa ukuguga.
Kumaleko okuqala yi-fusion edityanisiweyo ye-epoxy, ubukhulu bayo bukhulu kune-100μm. (FBE＞100μm)
Uluhlu lwesibini lunamathelisa, oluthi lubophe i-epoxy kunye ne-PE layers. (AD: 170 ~ 250μm)
Umaleko wesithathu PE umaleko nto leyo polyethylene iingenelo anti-amanzi, ukuxhathisa umbane kunye nomonakalo anti mechanical. (φ300-φ1020mm)
Ngoko ke, umbhobho wokugquma we-3PE uhlanganiswe kunye neenzuzo ze-FBE kunye ne-PE. Yeyiphi na ngakumbi nangakumbi esetyenziswa ngokubanzi kwimibhobho engcwatyiweyo yokuthutha amanzi, igesi kunye ne-oyile.
