Fusion Bonded Epoxy FBE Powder Coat for 3LPE Pipeline

I-Fusion Bonded Epoxy (FBE) yomgubo wokugquma isetyenziswa ngokuqhelekileyo njengengubo yokukhusela umhlwa kwimibhobho ye-3LPE. Isetyenziswe kumphezulu wangaphandle wombhobho ukubonelela ngomqobo osisigxina kunye nokukhusela ngokuchasene nokubola.

Ingubo yomgubo we-FBE idla ngokusetyenziswa kusetyenziswa iindlela zokutshiza nge-electrostatic okanye iindlela zokubeka ulwelo . Ingubo iyafudunyezwa ize inyibilike phezu komphezulu wombhobho, yenze ingubo eqhubekayo nefanayo. Nje ukuba ipholile, ingubo ye-FBE inika ukunamathela okuhle kakhulu kunye nokumelana neekhemikhali, ukufuma kunye nokukrala.

Inkqubo yokugquma imibhobho ye-3LPE inemigangatho emithathu: i-primer ye-FBE, i-adhesive layer, kunye ne-polyethylene topcoat. I-Fusion Bonded Epoxy primer isebenza njenge-agent edibeneyo phakathi kwendawo yentsimbi kunye ne-adhesive layer, iqinisekisa ukubambelela kakuhle. I-adhesive layer inika ukhuseleko olongezelelweyo lwe-corrosion kwaye isebenza njengoluhlu lwe-bonding kwi-topcoat ye-polyethylene.

PECOAT® iphuhliswe ngokudibeneyo kwaye ivelise i-high-performance Fusion Bonded Epoxy powder coating, eyona nto iqulethwe ngama-resins akhethekileyo kwaye yenziwe ngokucokisekileyo kunye nezongezo ezigqwesileyo kunye nezithako ezithile. Inokuhambelana kakuhle kunye ne-adhesive copolymer kwi-3PE anti-corrosion kwimibhobho, kwaye isetyenziselwa ukugubungela okanye ukucwiliswa kweenkqubo zokuqhuba imisebenzi kunye nokwakhiwa kumacandelo ombhobho wensimbi. Ayineli nje ukuxhathisa okugqwesileyo kwe-corrosion kodwa kunye neempawu ezibalaseleyo zoomatshini, ziyenza ilungele iimeko ezahlukeneyo zemozulu kwihlabathi liphela.

Imibala: Grey, blue, green, etc. ingenziwa ngokwezifiso.
Imigangatho yokwenziwa: GB/T 23257-2017 kunye neSY/T 0315-2005.

iimpawu

1. Umbala ofanayo, akukho agglomeration okanye iqhuma
2. Amandla okudibanisa okuphezulu kunye ne-anti-corrosion layer adhesive
3. Ukusebenza okuphezulu kwe-cathodic peeling kunye namandla e-dielectric
4. Ukuchasana okunamandla kwi-corrosion yeekhemikhali ezifana ne-asidi, i-alkali

Ukwaleka ukusebenza

Indlela yokusetyenziswa kwe-Fusion Bonded Epoxy

1. Susa i-Rust, i-oyile kunye ne-Debris kumphezulu we-Ssimbi: ukuqhushumba kwembumbulu kunye nonyango lokuqhunyiswa kwesanti ukuya kwinqanaba le-Ss2.5 elichazwe kwi-GB/T8923; ubunzulu bepateni yeAnchor ye-50-70um; .
2. Ukushisa kwangaphambi kokushisa kweengxenye ze-anticorrosive kufuneka kulawulwe kwi-200-240 ℃, kwaye ukwakhiwa kwangempela kunokulungiswa ngokwemiqathango yokwakhiwa kwendawo.
3. Sebenzisa indlela yokutshiza ye-electrostatic kumsebenzi wokwakha (i-voltage ephakathi kwe-60-90kv, umgama wokutshiza phakathi kwe-150-200mm), ubukhulu be-coating ye-100-150um.
4. Indawo yokwakha kufuneka yome kwaye icoceke.
5. I-epoxy powder kufuneka ivulwe kwaye isetyenziswe njengoko ifunekayo, kwaye iimveliso eziseleyo kufuneka zivalwe ngexesha ukuphepha ukungcoliseka kothuli kunye nomswakama emoyeni.

Ukupakishwa kunye nokugcinwa kwe-Fusion Bonded Epoxy

1. Ikhathoni kunye nengxowa yokupakisha etywiniweyo yangaphakathi: 25kg / Ibhokisi.
2. Kuphephe ukuvezwa elangeni, imvula, kude nomlilo, ubushushu bufanelekile ≤35℃.
3. Ukuphakama kwe-stack ≤5 iileyile zokuthintela uxinzelelo, qinisekisa ukungena komoya, ukukhusela umswakama (umswakama ohambelanayo <75%).
4. Ubomi beshelufu yeenyanga ezili-12.

Impilo, uKhuseleko kunye nokuKhuselwa kokusiNgqongileyo

1. Ngexesha lokusetyenziswa, kuyimfuneko ukuqinisa ukukhuselwa ngokugqoka iimaski zothuli kunye nezibuko zokukhusela uthuli ekungeneni emlonyeni nasemehlweni.
2. Kufuneka isetyenziswe kwindawo enomoya ococekileyo, kwaye ukugxininiswa kothuli emoyeni kufuneka kube ngaphantsi kwe-20g / cm3 ukuphepha ukuqhuma.
3. Ukutshaya akuvumelekanga kwindawo yokusetyenziswa, kwaye amadangatye avulekileyo anqatshelwe ngokungqongqo. Kufuneka kunikwe izixhobo zokucima umlilo, kwaye izicwangciso zongxamiseko kufuneka zilungiswe kwangethuba.
4. Ukuba uphefumlelwe okanye ukutyile, funa unyango ngokukhawuleza.
5. Inkunkuma eshiyekileyo ayinakuphinda isetyenziswe kwaye kufuneka ithunyelwe kwindawo yokulahla inkunkuma ukuze iphathwe kwindawo enye.
