Iibka Kulul Dhumucyada Yaryar ee Weyn ee Dhuumaha Ka-hortagga Daxalka ee Gaadiidka dareeraha ah
Waqtigan xaadirka ah, khasaaraha sanadlaha ah ee caalamiga ah ee ka dhashay daxalka tuubooyinka birta ayaa gaaraya ilaa 500 bilyan oo doolarka Mareykanka ah.Tuubooyinka birta ee ka hortagtaa waxay si wax ku ool ah uga hortagi karaan ama hoos u dhigi karaan daxalka, waxay dheereynayaan nolosha adeegga tubooyinka birta, waxayna yareynayaan kharashyada hawlgalka ee tuubooyinka birta.
Kala-soocidda: Kala-soocidda gidaarka gudaha ee ka-hortagga daxalka (daahan epoxy-dareeraha IPN8710 ka-hortagga daxalka, isku-dhafka budada epoxy anti-corrosion);Kala-soocidda gidaarka dibadda ee ka-hortagga daxalka, 2PE / 3PE-daxalka ka-hortagga iyo hal-lakabka PE-daxalka;Daamurka dhuxusha epoxy ee ka hortagga daxalka;daahan dibadda ka-hortagga daxalka;habka anti-daxalka.
Qalabka: FBE Epoxy budada fulinta ka-hortagga daxalka SY/T0315-2005 "Qeexidda Farsamada ee Fusion-ka-lakabka ah ee Dahaarka Epoxy Powder ee Dhuumaha Birta"
2PE/3PE fulinta ka hortagga daxalka GB/T23257-2009 "Heerka farsamada ee dahaarka dibadda ee polyetylen ee dhuumaha birta la aasay"
Heerka ka saarida miridhku dusha sare ee ka-hortagga daxalka: ciid-qarxinta iyo ka saarista miridhku ee dusha sare ee tuubada birta waxay gaadhaan heerka Sa2 1/2 iyadoo loo eegayo shuruudaha GB/T8923-2008, iyo qoto dheer ee qaabka barroosinka ee dusha birta tuubada waa 40-100μm.
Qeexida: tuubo bir ah oo aan kala go 'lahayn, tuubo bir ah oo wareeg ah, tuubbo toosan oo tol ah, tuubo galvanized ah, tuubo bir ah, dhexroorkeeda dibadda waa 16-800mm
Anti-corrosion birta wax saldhigga ah waxaa ka mid ah tuubo wareeg ah, tuubo tol toosan, tuubo aan xuduud lahayn, iwm Waxaa si weyn loo isticmaalaa in gaadiidka biyaha fogfog, batroolka, warshadaha kiimikada, gaaska dabiiciga ah, kulaylka, daaweynta bulaacada, isha biyaha, buundada, birta qaab dhismeedka, gaadiidka biyaha badda ee dalkeena.Qaybaha injineernimada tuubooyinka sida tuullaynta.
Marka lagu daro hagaajinta nolosha adeegga ee tuubooyinka birta iyada oo loo marayo anti-corrosion, waxa kale oo lagu muujiyaa dhinacyada soo socda:
1. Isku-dar xoogga farsamada ee tuubada birta leh caabbinta daxalka ee caagga;
2. Daahan derbiga dibadda waa in ka badan 2.5mm, adkaysi u xagashada iyo kuuskuusan;
3. Isku-dhafka derbiga gudaha waa mid yar, 0.0081-0.091, kaas oo yareynaya isticmaalka tamarta;
4. Derbiga gudaha waxa uu la kulmaa heerarka caafimaadka qaranka;
5. Darbiga guduhu waa siman yahay, ma fududa in la miisaamo, wuxuuna leeyahay hawl is-nadiifin ah
