Sab nraud 3LPE Txheej DIN 30670 Sab hauv FBE Txheej
Kev piav qhia txog khoom
Cangzhou Spiral Steel Pipes Group Co., Ltd muaj 4 kab ntau lawm ntawm kev tiv thaiv xeb & rwb thaiv tsev kub los ua 3LPE txheej thiab FBE txheej. Qhov siab tshaj plaws sab nraud txoj kab uas hla tuaj yeem yog 2600 hli.
Cov txheej txheej no tsim nyog rau kev tiv thaiv cov kav hlau faus lossis cov kav dej hauv qab dej ntawm qhov kub tsim ntawm -40 ℃ txog + 80 ℃.
Tus qauv tam sim no qhia txog cov kev cai rau cov txheej txheem uas siv rau cov kav hlau uas tau vuam ua ke thiab cov khoom siv uas siv rau kev tsim cov kav dej rau kev xa cov kua lossis cov pa roj.
Kev siv cov qauv no ua kom ntseeg tau tias PE txheej muab kev tiv thaiv txaus rau cov khoom siv thermal thiab tshuaj lom neeg uas tshwm sim thaum lub sijhawm ua haujlwm, kev thauj mus los, kev khaws cia thiab kev teeb tsa.
Cov txheej txheej extruded muaj peb txheej: ib qho epoxy resin primer, ib qho PE nplaum thiab ib txheej extruded polyethylene sab nraud. Cov epoxy resin primer yog siv ua hmoov. Cov nplaum tuaj yeem siv ua hmoov lossis los ntawm extrusion. Rau cov txheej txheej extruded, qhov sib txawv yog ua los ntawm kev extrusion tes tsho thiab daim ntawv extrusion. Sintered polyethylene coatings yog ib lossis ntau txheej. Cov hmoov polyethylene raug fused rau ntawm qhov khoom pre-heated kom txog thaum ncav cuag qhov tuab txheej xav tau.
Epoxy resin primer
Cov tshuaj epoxy resin primer yuav tsum tau siv rau hauv daim ntawv hmoov. Qhov tuab tsawg kawg nkaus ntawm txheej yog 60μm.
PE nplaum
Cov nplaum PE tuaj yeem siv ua hmoov lossis extruded. Qhov tuab ntawm txheej tsawg kawg yog 140μm. qhov yuav tsum tau muaj zog tev tawm sib txawv nyob ntawm seb cov nplaum puas tau siv ua hmoov lossis tau extruded.
Txheej polyethylene
Cov txheej polyethylene no siv los ntawm kev sintering los yog los ntawm tes tsho los yog daim ntawv extrusion. Cov txheej no yuav tsum tau txias tom qab siv kom tsis txhob muaj kev hloov pauv tsis xav tau thaum thauj mus los. Nyob ntawm qhov loj me me, muaj cov nqi tsawg kawg nkaus rau qhov tuab ntawm cov txheej ib txwm muaj. Yog tias muaj kev thauj khoom ntau ntxiv, qhov tuab ntawm cov txheej tsawg kawg nkaus yuav tsum tau nce ntxiv 0.7 hli. qhov tuab ntawm cov txheej tsawg kawg nkaus tau muab rau hauv lub rooj 3 hauv qab no.
