Ngaphandle 3LPE Coating DIN 30670 Ngaphakathi FBE Coating

Inkcazelo emfutshane:

Lo mgangatho uchaza iimfuno zemveliso-esetyenzisiweyo kwi-polyethylene-based based coatings kunye nenye okanye i-multi-layered sintered polyethylene-based based coatings ukwenzela ukukhusela ukuhlwa kwemibhobho yentsimbi kunye nokufakelwa.

Ingcaciso yeMveliso

I-Cangzhou Spiral Steel Pipes Group Co., Ltd inemigca emi-4 yemveliso ye-anticorrosion & insulation ye-thermal ukwenza i-3LPE yokwambathisa kunye ne-FBE yokwaleka.Ubuninzi bangaphandle ububanzi bunokuba yi-2600mm.

Iingubo zilungele ukukhuselwa kwimibhobho yentsimbi engcwatywe okanye engaphantsi kwamanzi kumaqondo obushushu oyilo lwe -40 ℃ ukuya +80 ℃.

Umgangatho okhoyo uxela iimfuno zokwaleka ezisetyenziswa kwimibhobho yentsimbi edityanisiweyo kunye nezixhobo ezisetyenziselwa ukwakhiwa kwemibhobho yokuhambisa ulwelo okanye iigesi.

Ukusebenzisa lo mgangatho kuqinisekisa ukuba i-PE yokugqoka inika ukhuseleko olwaneleyo kwimithwalo ye-thermal kunye neekhemikhali ezenzeka ngexesha lokusebenza, ukuthutha, ukugcinwa kunye nokufakwa.

Iingubo ezongezelelweyo ziquka imigangatho emithathu: i-epoxy resin primer, i-adhesive ye-PE kunye ne-polyethylene ekhutshiweyo yangaphandle.I-epoxy resin primer isetyenziswe njengomgubo.I-adhesive ingasetyenziswa mhlawumbi njengomgubo okanye nge-extrusion.Kwiingubo ezikhutshiweyo ukwahlula kwenziwa phakathi kwe-sleeve extrusion kunye ne-sheet extrusion.Iingubo ze-polyethylene ze-Sintered ziyinkqubo enye okanye ezininzi.I-polyethylene powder idityaniswe kwi-pre-heated component de kufike ubungakanani obufunwayo bokugquma.

I-epoxy resin primer

I-epoxy resin primer kufuneka ifakwe kwifomu yomgubo.Ubuncinci bobukhulu bomaleko yi-60μm.

I-PE encamathelayo

I-adhesive ye-PE ingasetyenziswa kwifom ye powder okanye ikhutshwe.Ubuncinci bobukhulu bomaleko yi-140μm.iimfuno zamandla e-peel ziyahlukahluka kuxhomekeke ekubeni i-adhesive isetyenziswe njengomgubo okanye ikhutshwe.

Polyethylene ukutyabeka

I-polyethylene yokugqoka isetyenziswe okanye i-sintering okanye nge-sleeve okanye i-sheet extrusion.Ukugquma kufuneka kupholiswe emva kwesicelo ukuphepha ukuguqulwa okungafunekiyo ngexesha lokuthutha.Kuxhomekeka kubungakanani begama, kukho amaxabiso amancinci ahlukeneyo obungakanani obuqhelekileyo bokugquma.Kwimeko yokunyuka kwemithwalo yomatshini ukutyeba kobuncinane bomaleko kuya kwandiswa nge-0.7mm.ubuncinane bomaleko obunzima bunikwe kwitheyibhile yesi-3 engezantsi.
