3pe anticorrosion simbi pombi

3pe anticorrosion simbi pombi inosanganisirapombi yesimbi isina musono, spiral simbi pombiuyeNdaona pombi yesimbi. Iyo matatu-layer chimiro che polyethylene (3PE) anticorrosion coating inoshandiswa zvakanyanya muindasitiri yepetroleum pombi yekudzivirira kwayo kunaka kwekuora, mvura uye gasi permeability uye michina.Iyi anti-corrosion kurapwa inonatsiridza zvakanyanya kushorwa kwepombi yesimbi, iyo inokodzera pombi masisitimu akadai sekutapurirana oiri, kutapurirana gasi, kufambisa kwemvura uye kupa kupisa.

Chimiro che 3PE anticorrosion simbi pombi yekutanga layer:
Epoxy poda coating (FBE):

Ukobvu hunenge 100-250 microns.

Ipa yakanakisa adhesion uye makemikari corrosion resistance, uye pamusoro pepombi yesimbi yakanyatsobatanidzwa.

 

Chikamu chechipiri: binder (Adhesive):

Ukobvu hunosvika 170-250 microns.

Icopolymer binder inobatanidza epoxy poda coating kune polyethylene layer.

 

Yechitatu layer: Polyethylene (PE) coating:

Ukobvu hunenge 2.5-3.7 mm.

Inopa mechanical dziviriro uye denga rekudzivirira mvura kubva pakukuvadzwa kwemuviri uye kupinza hunyoro.

Kugadzira maitiro e3PE anti-corrosion simbi pombi
1. Kugadziriswa kwepamusoro: pamusoro pepombi yesimbi inoputirwa nejecha kana kupfurwa-kuputika kubvisa ngura, ganda rine oxidized uye kumwe kusvibiswa uye kuvandudza kusungirirwa kwekuputira.

2. Kupisa pombi yesimbi: pombi yesimbi inopisa kune imwe tembiricha (kazhinji 180-220 ℃) ​​kukurudzira kusanganiswa uye kunamatira epoxy powder.

3. Kupfekedza epoxy powder: zvakaenzana pfapfaidza epoxy powder pamusoro pepombi inopisa yesimbi kuti iite chikamu chekutanga chekuputira.

4. Shandisa binder: Isa copolymer binder pamusoro pe epoxy powder coating kuti uve nechokwadi chekubatana kwakasimba ne polyethylene layer.

5. Polyethylene coating: Yekupedzisira polyethylene layer inoshandiswa pamusoro pebinder layer kuti iite yakazara matatu-layer structure.

6. Kutonhodza uye kurapa: Iyo pombi yesimbi yakavharwa inotonhodzwa uye inoporeswa kuti ive nechokwadi chekuti mativi matatu ekuputira akanyatsobatanidzwa kuti aite yakasimba anti-corrosion layer.

Zvimiro uye zvakanakira 3PE anti-corrosion simbi pombi

1. yakanakisa anti-corrosion performance: iyo matatu-layer coating structure inopa yakanakisa anti-corrosion kuchengetedzwa uye yakakodzera kune dzakasiyana siyana dzakaoma mamiriro akadai se acidic uye alkaline, nzvimbo dzemugungwa uye zvichingodaro.

2. yakanaka mechanical properties: iyo polyethylene layer ine yakanakisa kukanganisa uye friction resistance uye inogona kumira kunze kwekukuvara kwemuviri.

3. Kupisa kwepamusoro uye kuderera kwekushisa: 3PE anticorrosion layer inogona kuchengetedza kushanda kwakanaka munzvimbo dzose dzakakwirira uye dzakaderera, uye haisi nyore kuputika nekudonha.

4. Hupenyu hurefu hwebasa: 3PE anti-corrosion simbi pombi sevhisi hupenyu hunosvika makore makumi mashanu kana kunyange kureba, kuderedza pombi yekugadzirisa uye kutsiva mutengo.

5. kunamatira kwakanakisisa: epoxy powder coating uye simbi pombi pamusoro uye pakati binder layer ine adhesion yakasimba kudzivirira kupfekwa kubva peeling.

 
Nzvimbo dzekushandisa

1. Oiri uye gasi kutakurwa: inoshandiswa kutakura kureba kwemafuta uye magasi egasi mapaipi kudzivirira kukora uye kubuda.

2. Pombi yekufambisa yemvura: inoshandiswa mumaguta emvura, dhizaini, kuchenesa tsvina uye mamwe mapombi emvura masisitimu, kuve nechokwadi chekuchengetedzwa kwemhando yemvura.

3. pombi yekudziya: inoshandiswa pakufambisa mvura inopisa mukati mepakati yekudziya system kudzivirira kuparara kwepombi uye kurasikirwa nekupisa.

4. pombi yeindasitiri: inoshandiswa muindasitiri yemakemikari, simbi, simba remagetsi uye dzimwe nzvimbo dzeindasitiri dzepombi yekugadzira, kuchengetedza pombi kubva mukuora media.

5. Marine engineering: inoshandiswa mumapaipi epasi pemvura, mapuratifomu emugungwa uye mamwe mainjiniya emugungwa, kurwisa kuparara kwemvura yegungwa uye zvipenyu zvemugungwa.
