Dahaarka 3LPE ee ka baxsan DIN 30670 Gudaha Dahaarka FBE
Sharaxaada Alaabta
Cangzhou Spiral Steel Pipes Group Co., Ltd waxay leeyihiin 4 khadadka wax soo saarka ee anticorrosion & kuleylka kuleylka si ay u qabtaan daahan 3LPE iyo daahan FBE.Dhexroorka dibadda ugu badan wuxuu noqon karaa 2600mm.
Dahaarku waxay ku habboon yihiin ilaalinta tuubooyinka birta ee la aasay ama la quusiyay ee heerkulka naqshadeynta -40 ℃ ilaa + 80 ℃.
Heerka hadda jira wuxuu qeexayaa shuruudaha dahaarka lagu dabaqo tuubooyinka birta ah ee alxanka leh iyo qalabyada loo isticmaalo dhismaha dhuumaha gudbinta dareeraha ama gaaska.
Codsashada heerkan waxay hubisaa in daahan PE ay bixiso difaac ku filan oo ka dhan ah kulaylka farsamada iyo culeyska kiimikada ee dhacaya inta lagu jiro hawlgalka, gaadiidka, kaydinta iyo rakibidda.
Dahaarrada dibadda loo saaray waxay ka kooban yihiin saddex lakab: primer resin epoxy, xabagta PE iyo lakabka sare ee polyetylen-ka.Saliida epoxy resin primer waxa loo mariyaa sidii budo ahaan.Xabagta waxaa lagu dabaqi karaa sida budo ama extrusion.Dahaarrada dibadda loo saaray waxaa lagu kala duwan yahay ka-baxa gacmaha iyo extrusion-ka xaashida.Dahaarka polyetylen-ka-daaqsan waa hal ama habab lakabyo badan.Budada polyetylenku waxay ku darsataa qaybta hore loo sii kululeeyay ilaa dhumucda dahaarka la rabo laga gaaro.
Epoxy resin primer
Saliida epoxy resin primer waa in lagu mariyaa qaab budo ah.Dhumucda lakabka ugu yar waa 60μm.
xabagta PE
Xabagta PE waxaa lagu dabaqi karaa qaab budo ah ama laga saari karaa.Dhumucda lakabka ugu yar waa 140μm.Shuruudaha xoogga diirka way kala duwan yihiin iyadoo ku xiran haddii koollada loo mariyay budo ahaan ama la soo saaray.
daahan polyetylen
Daahan polyetylenka ah waxaa lagu dabaqaa ha ahaato mid jeexdin ah ama gacan-saarid ama xaashida.Dahaarka waa in la qaboojiyaa ka dib codsiga si looga fogaado isbeddelka aan loo baahnayn inta lagu jiro gaadiidka.Iyada oo ku xidhan cabbirka magaca, waxa jira qiimayaal kala duwan ee ugu yar ee dhumucda dahaarka caadiga ah.Xaaladda culeyska makaanikada ee kordhay, dhumucda lakabka ugu yar waa in lagu kordhiyo 0.7mm.dhumucda lakabka ugu yar ayaa lagu sheegay shaxda 3 ee hoose.
