Kwizicelo zoshishino, ngokukodwa kwicandelo leoli kunye negesi, ukunyaniseka kombhobho wensimbi kubalulekile. Enye yezona ndlela zisebenzayo zokuqinisekisa ixesha elide kunye nokuqina kwale mibhobho kukusetyenziswa kwe-fusion bonded epoxy (FBE) iingubo. Ukuqonda imigangatho yokugquma i-FBE kubalulekile kuye nabani na obandakanyekayo ekuthengeni, ekufakeni okanye ekugcinweni kombhobho wamanzi entsimbi kunye nezixhobo.
Iingubo ze-FBE zisetyenziswa ikakhulu kwiintlobo ezahlukeneyo zemibhobho yentsimbi, kubandakanywa i-SSAW (i-Spiral Submerged Arc Welded) imibhobho, i-ERW (i-Electric Resistance Welded) imibhobho, i-LSAW (i-Longitudinal Submerged Arc Welded) imibhobho, imibhobho engenamthungo, kunye nezinto ezahlukeneyo zokufakelwa ezifana ne-elbows, kunye ne-teaters, kunye ne-teaters. Injongo ephambili yale ngqungquthela kukubonelela ngokukhuselwa kwe-corrosion, okuyimfuneko ukugcina ukunyaniseka kwesakhiwo sombhobho kwixesha elide.
Yintoni iFBE ukutyabeka?
I-FBE yokwambathisa yi-thermosetting epoxy powder efakwe kumphezulu wombhobho wentsimbi. Inkqubo yesicelo ibandakanya ukufudumeza umbhobho kwiqondo lokushisa elithile kwaye emva koko usebenzise i-epoxy powder, enyibilikayo kwaye yenza ibhondi eqinile kunye nomphezulu wombhobho wensimbi. Le nkqubo idala i-coat egudileyo, ehlala ixesha elide kunye nekhemikhali ekwazi ukumelana neemeko zendalo.
Ukubaluleka kwemigangatho yokugquma i-FBE
Ukuthotyelwa kwemigangatho yokugquma kwe-FBE kubalulekile ngenxa yezi zizathu zilandelayo:
1. Ukuxhatshazwa kwe-Corrosion: Umsebenzi oyintloko we-FBE yokugquma kukukhusela isinyithi kwi-corrosion. Imigangatho efanelekileyo iqinisekisa ukuba i-coating isetyenziswe ngokuchanekileyo kwaye ihlangabezana nobukhulu obufunekayo kunye neemfuno zokubambelela ukubonelela ngokukhuselekileyo.
2. Uqinisekiso loMgangatho: Ngokulandela imigangatho esekiweyo, abavelisi banokuqinisekisa umgangatho weemveliso zabo. Oku kubaluleke kakhulu kwiinkampani ezivelisa izixa ezikhulu zemibhobho yentsimbi, umzekelo, inkampani ene-asethi ye-680 yezigidi zeeyuan, imveliso yonyaka yeetoni ezingama-400,000 zemibhobho yentsimbi ejikelezayo, kunye nexabiso lemveliso ye-yuan eyi-1.8 yebhiliyoni.
3. Ukuthobela: Amashishini amaninzi aphantsi kolawulo olungqongqo lwezixhobo kunye neenkqubo ezisebenza kuzo. Ukuthobela imigangatho yokugquma i-FBE kunceda iinkampani ziphephe imiba esemthethweni kwaye zigcine isidima sabo semarike.
4. Ixesha elide kwaye linokwethenjelwa: Ukusetyenziswa ngokufanelekileyo kwengubo ye-FBE kunokwandisa kakhulu ubomi benkonzo yeepayipi zetsimbi. Oku kuthembeka kubalulekile kumashishini axhomekeke kule mibhobho ukuthutha amanzi, i-oyile kunye negesi.
IsitshixoFBE imigangatho yokwaleka
Xa uqwalasela iingubo ze-FBE, kubalulekile ukuqonda iindlela eziphambili zokusetyenziswa kwazo:
- I-ASTM D638: Lo mgangatho uchaza iipropathi ze-tensile zeplastiki (kubandakanywa neengubo ze-FBE) ukuqinisekisa ukuba ziyakwazi ukumelana noxinzelelo olufunyenwe ekusebenziseni.
- I-ASTM D3359: Lo mgangatho uvavanya ukunamathela kwengubo kwi-substrate, eyona nto ibalulekileyo ekuqinisekiseni ukuba i-FBE yokugqoka ihlala injalo ngokuhamba kwexesha.
- I-AWWA C213: Lo mgangatho ujongene ngqo neemfuno ze-fusion-bonded epoxy coatings kumbhobho wamanzi wensimbi, ukubonelela ngesikhokelo sokusetyenziswa, ukuhlolwa kunye nokuvavanya.
ukuququmbela
Isishwankathelo, ukuqonda imigangatho yokugquma kwe-FBE kubalulekile kuye nabani na obandakanyekayo kwishishini lombhobho wensimbi. Ukugxininisa ekukhuselweni kwe-corrosion, ukuqinisekiswa kwekhwalithi, kunye nokuthotyelwa kokulawula, le migangatho idlala indima ebalulekileyo ekuqinisekiseni ubomi benkonzo kunye nokuthembeka kwemibhobho yensimbi kunye nokufakelwa. Iinkampani ezibeka i-premium ekubambeleleni kule migangatho, njengalezo zinamandla okuvelisa amandla kunye ne-asethi, azikwazi nje ukuphucula umgangatho wemveliso kodwa ziqinise indawo yazo kwimarike yokhuphiswano. Njengoko imfuno yombhobho wensimbi ehlala ixesha elide kwaye enokwethenjelwa iqhubeka ikhula, ukubaluleka kweengubo ze-FBE kunye nemigangatho yesicelo sabo iya kuqhubeka ikhula.
