Iyo yapedzwa spiral simbi pombi inoburitswa mushure mekutonhora kwemvura, asi mushure mezvose, mushure mekupisa kwakanyanya kupisa, tembiricha yespiral simbi pombi ichiri yakakwira zvakanyanya mushure mekutonhora kwemvura, saka zvinotevera zvinofanirwa kucherechedzwa mushure mekunge pombi inotenderera yabviswa chirimo :

Imwe: Mukugadzira spiral simbi pombi, iyo epoxy poda uye chinonamira chinofanira kunge chakakura 1% kupfuura zvamazuva ese, kuitira kuti uwane ukobvu chaihwo hunodiwa.

Chechipiri: Usafumure kune tembiricha yakakwira mushure mekunge spiral simbi pombi yabviswa pamutsetse.Kuratidzira kunogona kutungamirira nyore nyore kukuwedzera kwePE layer uye nokudaro rusvingo rwekunze rwepombi yesimbi, iyo isingazowana anti-corrosion effect.

Tatu: Usaoneswe kunaya mushure mekunge pombi yesimbi yespiral yabviswa pamutsetse.Zviri nyore kukonzera mvura kuyerera pajojo yepombi mushure mekunaya.

Zvina: Mushure mokunge pombi yesimbi inoputika yabviswa pamutsara, inofanira kuiswa panzvimbo yakati sandara, uye inofanira kuiswa pasi.Musasvisvina.Kana iyo extrusion mhando yakaiswa kanenge maawa makumi maviri nemana, iyo PE layer inofanirwa kusungirirwa zvachose kumadziro ekunze kwepombi yesimbi..

3PE anti-corrosion chimiro:

Ordinary giredhi ≥ 0.70 imwe layer ye primer + imwe layer yemukati yemukati + imwe layer yekunze bhandi

Yakasimbiswa giredhi ≥ 1.40 layer ye primer + yemukati layer (inopindirana ndeye 50 ~ 55% ye tepi hupamhi)

Imwe dhizaini yekunze tepi (inopindirana ndeye 50 ~ 55% ye tepi hupamhi)

Inonyanya kushandiswa pakufambisa kwemafuta uye gasi rechisikigo;nzvimbo yekunze yemapombi esimbi akavigwa akadai semvura uye dhiraivha uye gasi kutakura mumakemikari uye kuvakwa kwemadhorobha kune anti-corrosion, iyo ine hunhu hwekuvaka nyore uye pasina kusvibiswa.Polyethylene PE anti-corrosion adhesive tepi yakashandiswa zvakanyanya seyekunze anti-corrosion zvinhu pamafuta uye gasi simbi mapaipi kubvira kuma1960.Yakashandiswa kwemakore anopfuura makumi mana.Nekuda kwekuita kwayo kwakanaka kwe-anti-corrosion uye kuita kuri nyore kwekuvaka, yaita kuti ive anti-corrosion zvinhu zvemapombi.Iyo system ine imwe nzvimbo.Uye sezvo mabhizinesi ekugadzira tepi yepolyethylene yakavharira tepi anoramba achivandudza nekusimudzira polyethylene PE siyana uye mhando ye-anti-corrosion adhesive tepi, kuitira kuti iyo polyethylene PE inoshandisa anticorrosion adhesive tepi kuwedzera.
