Dhuumaha Birta Dahaarka Tayada Sare
Dhuumaha Birta Dahaarka Tayada Sare
(1) Habka wax soo saarka ee birta birta ah ee aan fiicnayn waxaa loo qaybin karaa dhowr qaybood oo aasaasi ah: kululaynta kulul (extrusion), qabow duuban (sawir) iyo tuubo kulul oo kulul.
(2) Marka loo eego habka wax soo saarka, tuubooyinka welded waxaa loo qaybin karaa tollayn toosan oo bir ah oo welded ah, tuubo bir ah oo wareeg ah, tuubo bir ah oo alxan leh, tuubo bir ah oo balaadhinta kulaylka.
Marka loo eego qaabka, tuubooyinka birta waxaa loo qaybin karaa: tuubo wareegsan, tuubo laba jibbaaran, tuubo afargees ah, octagonal, hexagonal, D-qaabeeya, pentagonal iyo tuubooyinka kale ee gaarka ah, tuubooyinka birta ee qaybta adag, tuubooyinka birta laba jibaaran, shan petal Tuubooyinka birta ee quincunx, tuubooyinka birta tolan, tuubooyinka birta jiingado, abuur qaraha tuubooyinka birta, tuubooyinka birta double convex, iwm.
Dhuumaha birta waxaa loo kala qaybin karaa: Dhuumaha birta ee dhuumaha, birta qalabka kulaylka, dhuunta birta warshadaha makaanik, tuubada birta ee batroolka iyo qodista juqraafiyeed, tuubada birta weel, tuubooyinka birta warshadaha kiimikada, tuubooyinka birta ujeedo gaar ah, iwm. Kala-soocidda daxalka ka-hortagga gidaarka gudaha: laalaabida dareeraha epoxy dahaarka ipn8710 ka-hortagga daxalka iyo isku-laabashada isku-laabashada ee ku xidhan budada epoxy-ka-hortagga.
Kala soocida derbiga dibadda ee ka-hortagga daxalka: laalaabida 2PE / 3PE-daxalka, hal-lakabka PE-daxalka iyo laalaabida epoxy dhuxusha asphalt-ka-hortagga.Heerka daxalka: FBE epoxy budada anti-daxalka waa in ay u hoggaansamaan SY / t0315-2005 qeexitaanka farsamada ee hal lakab oo fusion bonded epoxy budada dibadda ee dhuumaha birta, 2PE / 3PE daxalka anti-daxalka waa in ay u hoggaansamaan GB / t23257-2009 heerka farsamada daahan dibadda polyetylen ee dhuumaha birta la aasay, heerka ka saarida miridhku dusha sare anti-daxalka: ciid qarxinta dusha sare ee tuubada birta waa in ay gaaraan SA2 1/2 sida waafaqsan shuruudaha GB / t8923-2008, iyo qoto dheer ee hadhuudh barroosinka on the dusha tuubada birta waa inay ahaataa 40-100 μm.
Qalabka saldhigga ah ee tuubooyinka birta ee ka hortagga daxalka waxaa ka mid ah tuubooyinka wareega, tuubooyinka tolleynta tooska ah, tuubooyinka aan fiicnayn, iwm. ee Shiinaha, waxay si ballaaran u isticmaalaan beeraha injineernimada dhuumaha sida gudbinta biyaha fog, batroolka, warshadaha kiimikada, gaaska dabiiciga ah, kulaylka. , Daaweynta bulaacada, isha biyaha, buundada, qaab dhismeedka birta, gudbinta biyaha badda iyo tuulan.
Marka lagu daro hagaajinta nolosha adeegga ee birta birta iyada oo loo marayo anti-corrosion, waxa kale oo ay ka muuqataa dhinacyada soo socda:
1. Isku-dar xoogga farsamada ee tuubada birta leh caabbinta daxalka ee caagga ah;
2. Daahan derbiga dibadda waa in ka badan 2.5mm, adkaysi u xagashada iyo shil;
3. Isku-dhafka isku-dhafka ee gidaarka gudaha waa mid yar, 0.0081-0.091, yaraynta isticmaalka tamarta;
4. Derbiga gudaha waxa uu la kulmayaa heerarka caafimaadka qaranka;
5. Darbiga guduhu waa siman yahay oo ma fududa in la qiyaaso, oo leh hawl is-nadiifin ah.
