Kev daws teeb meem corrosion hauv ntses pub extruder pellet pub cov kab ntau lawm yuav tsum tau tsom mus rau peb qhov tseem ceeb: Ua ntej, lub cev muaj zog thiab cov ntsaws ruaj ruaj. Cov tshuaj tsuag ntsev thiab dej nkag tuaj yeem ua rau lub cev muaj zog tuaj yeem xeb thiab lo rau cov ntsaws ruaj ruaj, tiv thaiv lub cev tsis sib hloov. Txhawm rau hais txog qhov no, ua ntej tshem lub cev muaj zog, tshuaj tsuag lub cev muaj zog nrog xeb tshem tawm, cia nws sawv ntsug li 10 feeb, tom qab ntawd txhuam nws nrog cov ntawv xuab zeb zoo kom tshem tawm xeb. Hloov cov ntsaws ruaj ruaj nrog corrosion-resistant fluororubber sealants, siv cov sealant dej tsis zoo rau lub foob nto thaum lub sijhawm teeb tsa. Qhov thib ob, lub zog kis tau tus mob. Yog tias qhov txo qis hauv cov cw thiab crab feeder yog ua los ntawm cov hlau zoo tib yam, lawv tau yooj yim corroded, ua rau cov hniav hnav thiab tiv thaiv kev xa hluav taws xob. Hloov lawv nrog 316 stainless hlau iav kom ntseeg tau tias kev sib kis tau zoo. Thib peb, kho bolts ntawm rotating feed phaj. Corrosion thiab loosening tuaj yeem ua rau lub phaj pub rau tig dawb. Hloov lawv nrog titanium alloy bolts, zawm lawv thiab siv los tiv thaiv - xeb roj rau lub taub hau ntsia liaj qhov rooj.

Thaum muaj xwm txheej ceev, yog tias tshwj xeeb corrosion- cov khoom tiv thaiv tsis muaj nyob rau ntawm - qhov chaw, kev ntsuas ib ntus tuaj yeem ua tau: qhwv lub cav thiab lub thawv txuas nrog cov yeeb yaj kiab yas los tiv thaiv cov dej nkag mus ntxiv; qhwv zoo tib yam bolts nrog roj ua ntej installation kom qeeb corrosion. Tom qab kev daws teeb meem, kev kho kom zoo yuav tsum tau teem caij tam sim kom tsis txhob muaj qhov ua tsis tiav vim qhov kev ntsuas ib ntus ua tsis tiav.

Kev tiv thaiv- kev txhim kho corrosion yog ib qho kev daws teeb meem ntev: Hloov tag nrho cov hlau zoo tib yam ntawm cov khoom noj khoom haus nrog 316 stainless hlau lossis engineering yas, xws li siv nylon rau cov khoom noj thiab cov hlau tsis muaj steel rau cov pas nrig; ntxiv cov tshuaj tiv thaiv-corrosion txheej rau lub tsev nyob siv epoxy resin txau, nrog lub thickness tsis pub tsawg tshaj 0.5 hli; thaum txhim kho lub feeder, tsa lub cev muaj zog mus rau 50cm siab tshaj qhov siab tshaj dej theem, thiab nruab inclined ntws qhov nyob rau hauv qab ntawm lub hopper los tiv thaiv dej tsub zuj zuj thiab corrosion; nyob rau hauv niaj hnub tu, yaug lub feeder nrog dej tshiab txhua lub lim tiam thiab tshuaj tsuag hlau qhov chaw nrog ib tug tshwj xeeb marine anti-corrosion tus neeg saib xyuas txhua hli kom ntev kev pab cuam lub neej.
