Polyethylene vai paipa gaosi oloa faatau
Inner epoxy i fafo polyethylene anticorrosive paipa uamea o se ituaiga fou o paipa palasitika tu'ufa'atasi. O loʻo faʻapipiʻiina i lalo o le paipa uʻamea, epoxy resin ufiufi totonu ma polyethylene faʻapipiʻi fafo. O loʻo i ai mea faʻainisinia sili ona lelei, faʻamaʻi faʻamaʻi ma teteʻe matua. E fa'aaogaina lautele i le fa'asao vai, eletise eletise, vaila'au kemisi, suauu ma le tele o isi pisinisi.
O totonu o le epoxide pito i fafo polyethylene anticorrosive paipa ua vaevaeina i: totonu fusifusi fusifusia epoxy pa'u fafo tasi-mea polyethylene anticorrosive paipa uamea, vai totonu epoxy pa'u totonu tasi-apa polyethylene anticorrosive paipa uamea, totonu fusifusi fusipa'u epoxy pa'u pito fafo tolu-apa polyethylene ( 3PE) paipa u'amea fa'ama'i, epoxy vai totonu (ipn8710) pito i fafo e tolu-vaega polyethylene paipa u'amea
Fa'atulagaga o le epoxide totonu ma fafo monolayer polyethylene
1. mea fa'avae paipa u'amea: paipa u'amea seamless, paipa u'amea fa'aeletise (uu sa'o, u'elo li'o)
2. Lafoa'i fa'a'ele'ele i totonu: fa'apipi'i tu'umama fa'apipi'i epoxy pa'u pa'u, pa'u pa'u epoxy resin pa'u mamafa.
Ata fa'atulagaina o pito pito i fafo polyethylene
Ata fa'atulagaina o pito pito i fafo polyethylene
3. O lo'o fa'apalapala i fafo: fa'afefeteina le fa'afefeteina i fafo: fa'afefeteina le pa'u pa'u polyethylene e tasi fa'afefete
I totonu epoxide pito i fafo tolu-vaega polyethylene (3PE) fausaga
1. mea fa'avae paipa u'amea: paipa u'amea seamless, paipa u'amea fa'aeletise (uu sa'o, u'elo li'o)
2. Lafoa'i fa'a'ele'ele i totonu: fa'apipi'i tu'umama fa'apipi'i epoxy pa'u pa'u, pa'u pa'u epoxy resin pa'u mamafa.
3.O lo'o fa'apalapala i fafo: fa'afefete fa'afefete i fafo: fa'afefete fa'afefete fa'afefete fa'afefeteina fa'alava e tolu-vaega polyethylene. O le vaega pito i lalo ole epoxy resin pa'u fusu'aga, o le vaega ogatotonu e fa'afefete fa'afefete, ma o le pito pito i fafo o le polyethylene maualuga.
Fa'atusatusaga i le va o totonu ole epoxide fafo monolayer PE ma totonu ole epoxide fafo 3PE
O le polyethylene ma le epoxy e sili ona lelei le faʻafefeteina, ae e tofu lava ma ona lava lelei. O le polyethylene o se mea fa'avelavela ma lelei le fetu'una'i ma le fa'afefe. Ona o molelaʻau e le o polar, o le faʻaauau pea o le pipii i le va o le polyethylene ma le paipa uʻamea e le lelei; Epoxy resin o se mole mole polar ma vaega hydroxyl. I se vevela faapitoa, e faigofie ona tali atu i paipa uʻamea ma e malosi le pipii. Ae ui i lea, e le mafai ona teteʻe i faʻalavelave ona o se mea e faʻafefeteina. O le mea lea, o le tuʻufaʻatasiga o mea e lua e aʻafia i le tuʻufaʻatasiga sili ona lelei i totonu o le alamanuia anti-corrosion.
O le palasitika faʻapipiʻiina paipa paipa atinaʻe mai le uluai polyethylene totonu ma fafo i le epoxy i totonu ma fafo ona o faʻafitauli faʻapipiʻi, ae o le epoxy i fafo e le mafai ona faʻafefe i faʻalavelave. Mulimuli ane, na atiina ae i le lona tolu o augatupulaga i totonu epoxy fafo polyethylene, ae o le adhesion faafitauli o loo i ai pea pe a tuusaʻo le tasi-layer polyethylene ma le paipa uamea. Mulimuli ane, na fa'aleleia i le fa'atupulaga lona fa e tete'e a'e i totonu epoxy fafo tolu-laupapa fausaga polyethylene.
