Ke kūʻai aku nei ka mea hana paipu wai polyethylene
ʻO loko epoxy outer polyethylene anticorrosive steel pipe he ʻano hou o ka paipu hoʻohuihui kila kila. Hoʻokumu ʻia ia me ka substrate paipu kila, ka uhi i loko o ka resin epoxy a me ka uhi waho polyethylene. Loaʻa iā ia nā waiwai mechanical maikaʻi loa, ka pale ʻana i ka corrosion a me ke kūpaʻa ʻelemakule. Hoʻohana nui ia i ka mālama wai, ka mana uila, ka ʻoihana kemika, ka ʻaila a me nā ʻoihana ʻē aʻe.
Hoʻokaʻawale ʻia ka epoxide o waho polyethylene anticorrosive steel paipu i loko: i loko fusion i hoʻopaʻa ʻia i ka epoxy pauka waho hoʻokahi-layer polyethylene anticorrosive steel paipu, i loko wai epoxy pauka i loko o ka paipu kila polyethylene anticorrosive paipu, i loko fusion i hoʻopaʻa ʻia epoxy pauka waho ʻekolu-layer polyethylene ( 3PE) paipu kila anticorrosive, epoxy wai o loko (ipn8710) waho ʻekolu ʻāpana polyethylene anticorrosive paipu kila.
ʻO ka hui ʻana o ka epoxide i loko a me ka polyethylene monolayer waho
1. Paipu hao kumu waiwai: paipu kila ʻole, paipu kila wili uila (weld pololei, weld spiral)
2. Ka uhi ʻana i ka ʻino i loko: ka uhi ʻana i ka pauka epoxy i hoʻopaʻa ʻia, ka pauka resin epoxy i hoʻopaʻa ʻia.
Ke kaha kiʻi o ka polyethylene papa hoʻokahi o waho
Ke kaha kiʻi o ka polyethylene papa hoʻokahi o waho
3. Ka uhi ʻana i ka ʻino o waho: hoʻoheheʻe wela i ka pauka polyethylene one-layer
ʻO ka epoxide o loko waho ʻekolu-papa polyethylene (3PE) hale
1. Paipu hao kumu waiwai: paipu kila ʻole, paipu kila wili uila (weld pololei, weld spiral)
2. Ka uhi ʻana i ka ʻino i loko: ka uhi ʻana i ka pauka epoxy i hoʻopaʻa ʻia, ka pauka resin epoxy i hoʻopaʻa ʻia.
3.Ka uhi ʻana i ka ʻino o waho: hoʻoheheʻe wela i ka uhi polyethylene ʻekolu-papa. ʻO ka papa lalo he fusion bonded epoxy resin powder, ʻo ka papa waena he mea hoʻoheheʻe wela, a ʻo ka papa o waho he polyethylene kiʻekiʻe.
Hoʻohālikelike ma waena o loko epoxide waho monolayer PE a me loko epoxide waho 3PE
ʻO ka polyethylene a me ka epoxy ka maikaʻi o ka corrosion resistance, akā ua loaʻa i kēlā me kēia me kona pono ponoʻī. ʻO ka polyethylene kahi mea thermoplastic me ka maʻalahi a me ke kūpaʻa kūʻē. Ma muli o nā molekala non-polar, ʻilihune ka hoʻomau ʻana o ka adhesion ma waena o ka polyethylene a me ka paipu kila; ʻO ka epoxy resin kahi mole polar me nā hui hydroxyl. I kekahi mahana, ua maʻalahi ke hana me nā paipu kila a loaʻa ka adhesion ikaika. Akā naʻe, ʻaʻole ia e kū i ka hui ʻana no ka mea he mea thermosetting ia. No laila,ʻo ka hui pūʻana o nā meaʻelua no ka hui maikaʻi loa i kaʻoihana anti-corrosion.
Hoʻokumu ʻia ka ʻoihana paipu kila i hoʻopaʻa ʻia mai ka polyethylene kūloko a me waho a hiki i ka epoxy i loko a me waho ma muli o nā pilikia adhesion, akā ʻaʻole kūpaʻa ka papa epoxy waho i ka hui ʻana. Ma hope mai, ua hoʻomohala ʻia i ke kolu o ka hanauna i loko o ka epoxy waho polyethylene, akā mau ka pilikia adhesion i ka wā i hui pono ʻia ka polyethylene one-layer me ka paipu kila. ʻO ka hope, ua hoʻonui ʻia i ka ʻehā o ka hanauna anti-corrosion internal epoxy waho ʻekolu-layer structural polyethylene.
