Kwimveliso yemizi-mveliso, ukuthembeka nokuqina kwemibhobho yentsimbi kubaluleke kakhulu. Enye yezona ndlela zisebenzayo zokuqinisekisa ukuba le mibhobho iyakwazi ukumelana novavanyo lwexesha kunye nemingeni yokusingqongileyo kukusebenzisa ubuchwepheshe obuphambili bokugquma. Iingubo kunye nee-linings ze-Fusion-bonded epoxy (FBE) zezona zikhetho ziphambili zokukhusela ukugqwala. I-Cangzhou Spiral Steel Pipe Group Co., Ltd., umenzi ophambili onekomkhulu eCangzhou, kwiPhondo laseHebei, ibisoloko iphambili kule teknoloji ukususela ekusekweni kwayo ngo-1993.
Namhlanje, njengoko imibhobho yeoyile igqunywe nzulu ngaphantsi komhlaba kunye nemibhobho engaphantsi kwamanzi ixhathisa ukukhukuliseka kwetyuwa, itekhnoloji yokulwa nokugqwalaUkwaleka kunye nokuGcina iFbeinxulumene ngokuthe ngqo nokhuseleko kunye nobomi bemithambo yamandla. Njengeshishini eliphambili kwicandelo lokuvelisa imibhobho yentsimbi ejikelezayo eTshayina, iCangzhou Spiral Steel Pipe Group Co., Ltd. inika abathengi behlabathi izisombululo zemibhobho yentsimbi yokulwa nokugqwala ezinobomi benkonzo obungaphezu kweminyaka engama-20 ngokuxhomekeka kubuchwepheshe bayo bokugquma obuphuhliswe ngokuzimeleyo be-fusible epoxy powder (FBE). Isebenze iiprojekthi ezinkulu zasekhaya nezangaphandle ezingaphezu kwama-3,000 zizonke.
I-FBE Coating: Isikrweqe sobuchwepheshe esandisa ubomi bemibhobho yentsimbi kwiindawo ezixineneyo
Umgaqo wobugcisa
Umgubo we-epoxy unamathela ngokulinganayo kumphezulu wombhobho wentsimbi ngokutshiza nge-electrostatic, uze emva koko kwenziwe umaleko okhuselekileyo oxineneyo emva kokulungiswa kobushushu obuphezulu, nto leyo efezekisa:
Ukunamathelana okuphezulu: Amandla okubopha phakathiUmbhobho Wokugquma weFbekwaye isiseko sombhobho wentsimbi yi-≥70MPa (iphindwe kathathu kunomgangatho woshishino)
Ukhuseleko olupheleleyo lokusingqongileyo: Ayinakumelana nokukhukuliseka kwe-asidi, i-alkali, amanzi olwandle kunye neentsholongwane, ifanelekile kwiimeko zokusebenza ukusuka kwi--30℃ ukuya kwi-110℃
Uluhlaza kwaye lunobuhlobo nokusingqongileyo: 0 ukukhutshwa kwe-VOC, okuqinisekiswe yimigangatho yamazwe ngamazwe ye-ISO 21809-2
Izisombululo zokugquma ezisebenzayo zibalulekile, ingakumbi kumashishini apho imibhobho yentsimbi ichaphazeleka kwiimeko ezinzima zokusingqongileyo. Iingubo zepolyethylene ezisetyenziswa kwifektri ezisemgangathweni, kunye neengubo zepolyethylene ezifakwe kwifektri enye okanye ezininzi, zenzelwe ukubonelela ngokhuseleko oluqinileyo lokugqwala kwimibhobho yentsimbi kunye nezixhobo. Iingubo zeFBE zaziwa ngokunamathela kwazo okuhle kunye nokumelana nokugqwala. Le nkqubo ibandakanya ukufaka umaleko we-epoxy powder kumphezulu wombhobho wentsimbi uze uyifudumeze ukuze wenze ikhonkco eliqinileyo. Le ndlela ayikhuseli nje kuphela intsimbi ekugqwaleni kodwa ikwaphucula iimpawu zayo zoomatshini. Ekugqibeleni, imibhobho iyakwazi ukumelana neemeko ezinzima, iqinisekisa ubomi benkonzo obude kunye nokunciphisa iindleko zokulungisa.
I-Cangzhou Spiral Steel Pipe Group Co., Ltd. isebenzisa iinkqubo zokugquma ezikumgangatho ophezulu ukuqinisekisa ukuba yonke imveliso ihlangabezana nemigangatho ephezulu yoshishino. Ukuzinikela kwenkampani kumgangatho kubonakala kuvavanyo lwayo oluqatha kunye namanyathelo okulawula umgangatho, ukuqinisekisa ukuba yonke imibhobho egqunywe ngepeyinti isebenza ngokufanelekileyo kwiindawo ezifuna kakhulu.
Ngamafutshane, indima yeengubo ze-FBE kunye nee-linings ekukhuseleni iipayipi zentsimbi ayinakuthathelwa ingqalelo. Ngobuchule kunye nobuchwepheshe obuphambili beCangzhou Spiral Steel Pipe Group Co., Ltd., amashishini ahlukeneyo anokuqinisekiswa ukuba iipayipi zawo ziya kukhuselwa ngokufanelekileyo ekungcoleni nasekumonakaleni kwendalo. Njengoko inkampani iqhubeka nokuvelisa izinto ezintsha nokwandisa umgca wayo wemveliso, sihlala siliqabane elithembekileyo kumashishini afuna izisombululo zeepayipi zentsimbi ezithembekileyo nezihlala ixesha elide. Nokuba ukwishishini leoyile negesi, elokwakha, okanye nakweyiphi na enye imboni exhomekeke kwiipayipi zentsimbi, iCangzhou Spiral Steel Pipe Group Co., Ltd. lukhetho lwakho lokuqala lweepayipi zentsimbi ezigqunywe ngomgangatho ophezulu, ezihlala ixesha elide.
