Ma waho o ka 3LPE Coating DIN 30670 Inside FBE Coating
Hōʻike huahana
ʻO Cangzhou Spiral Steel Pipes Group Co., Ltd he 4 mau laina hana o ka anticorrosion & thermal insulation e hana i ka uhi 3LPE a me ka uhi FBE.Hiki ke 2600mm ke anawaena waho loa.
Ua kūpono nā uhi no ka pale ʻana i nā paipu kila i kanu ʻia a i ʻole nā paipu kila i ka hoʻolālā ʻana o -40 ℃ a + 80 ℃.
Hōʻike ka maʻamau o kēia manawa i nā koi no nā uhi i hoʻopili ʻia i nā paipu kila welded spirally a me nā mea pono i hoʻohana ʻia no ke kūkulu ʻana i nā pipeline no ka lawe ʻana i nā wai a i ʻole nā ea.
ʻO ka hoʻohana ʻana i kēia maʻamau e hōʻoiaʻiʻo i ka uhi ʻana o ka PE e hāʻawi i ka pale kūpono i ka mechanical thermal a me nā ukana kemika e kū nei i ka wā o ka hana, lawe ʻana, mālama a hoʻokomo.
ʻO nā ʻāpana hoʻoheheʻe ʻia he ʻekolu papa: kahi epoxy resin primer, kahi hoʻopili PE a me kahi papa waho polyethylene extruded.Hoʻohana ʻia ka primer epoxy resin e like me ka pauka.Hiki ke hoʻopili ʻia ka mea hoʻopili ma ke ʻano he pauka a i ʻole extrusion.No nā uhi extruded, hana ʻia kahi ʻokoʻa ma waena o ka extrusion lima a me ka extrusion pepa.ʻO nā pale polyethylene Sintered he ʻōnaehana hoʻokahi a i ʻole nā papahana lehulehu.Hoʻopili ʻia ka pauka polyethylene ma luna o ka mea i hoʻomehana ʻia a hiki i ka mānoanoa o ka uhi i makemake ʻia.
Epoxy resin primer
E hoʻohana ʻia ka epoxy resin primer ma ke ʻano pauka.ʻO ka mānoanoa papa haʻahaʻa he 60μm.
PE pipili
Hiki ke hoʻopili ʻia ka PE adhesive i ka pauka a i ʻole extruded.ʻO ka mānoanoa papa haʻahaʻa he 140μm.ʻokoʻa nā koi ikaika o ka peel ma muli o ka hoʻopili ʻia ʻana o ka mea hoʻopili e like me ka pauka a i hoʻokuʻu ʻia paha.
Ka uhi polyethylene
Hoʻohana ʻia ka uhi polyethylene ma o ka sintering a i ʻole ma ka lima a i ʻole ka extrusion pepa.Pono e hoʻomaʻalili ka uhi ma hope o ka noi ʻana e pale i ka deformation makemake ʻole i ka wā o ka lawe ʻana.Ma muli o ka nui inoa, aia nā ʻokoʻa liʻiliʻi liʻiliʻi no ka mānoanoa o ka uhi maʻamau.I ka hihia o ka hoʻonui ʻana i nā ukana mīkini, e hoʻonui ʻia ka mānoanoa papa liʻiliʻi e 0.7mm.hāʻawi ʻia ka mānoanoa papa liʻiliʻi ma ka papa 3 ma lalo nei.
