Qhia rau qhov zoo tshaj plaws abrasive xaiv rau shipbuilding thiab loj steel qauv anti-corrosion tej yaam num

Hauv kev tsim cov nkoj loj thiab cov qauv hlau loj los tiv thaiv corrosion, kev xaiv cov abrasives yuav tsum tau ua ke nrog cov khoom xws li xeb tshem tawm efficiency, nto zoo, kev tiv thaiv ib puag ncig thiab nqi. Qhov zoo thiab siv cov xwm txheej ntawm kev sib txawv abrasives yog qhov sib txawv, raws li hauv qab no:

Mainstream abrasive hom thiab cov yam ntxwv Qhov zoo thiab siv tau scenarios)

Hlautxhaj tshuaj/ hlaugrit

- Qhov kev tshem tawm xeb yog qhov siab heev, thiab nws tuaj yeem tshem tawm cov tuab oxide thiab xeb sai sai, uas yog tsim rau kev ua haujlwm siab xws li hull steel phaj pretreatment;

- Qhov saum npoo roughness yog tswj tau (txhim kho qhov tob ntawm 50-100μm), thiab qhov adhesion ntawm cov txheej tiv thaiv corrosion yog sib txuam heev;

- Nws tuaj yeem rov siv dua thiab rov siv dua, thiab tus nqi mus sij hawm tsawg tsawg.

- Cov xwm txheej siv tau: kev tsim khoom nkoj (xws li cov seem ntawm lub nkoj, cov qauv hauv tsev), cov txuas hniav loj thiab lwm cov khoom siv qib high-corrosion steel.

Garnet xuab zeb

- Lub hardness yog ze rau steel xuab zeb, cov xeb tshem tawm efficiency zoo heev, cov plua plav me me (tsis muaj silicon dawb), thiab nws ua tau raws li kev tiv thaiv ib puag ncig ntawm kev ua haujlwm qhib cua;

- Tsis muaj ntsev seem tom qab kev kho mob saum npoo av, uas tsis cuam tshuam rau qhov adhesion ntawm txheej, thiab nws yog qhov tsim nyog rau cov xwm txheej uas yuav tsum tau ua kom huv huv xws li kev kho nkoj.

- Cov xwm txheej siv tau: cov qauv hlau loj nrog kev tiv thaiv ib puag ncig nruj heev (xws li cov chaw cia khoom siv tshuaj) thiab qhib cua segmental xeb tshem tawm cov nkoj.

Copper slag (xws li tooj liab silica xuab zeb, ua los ntawm tooj liab smelting pov tseg slag)

- High hardness, xeb tshem tawm cov nyhuv tuaj yeem ncav cuag qib Sa2.0 ~ Sa3.0, tsis muaj kev pheej hmoo ntawm silicosis;

- Kev ua haujlwm siab: raws li cov khoom siv khib nyiab rov ua dua tshiab, cov khoom siv raw khoom yog tsawg.

- Cov xwm txheej siv tau: pretreatment ntawm cov khoom uas tsis yog-load-bearing Cheebtsam (xws li railings, brackets) thiab ib ntus hloov txheej txheej nyob rau hauv shipbuilding (xeb tshem tawm qib Sa2.0 yog txaus), tsis muaj ib tug sib sib zog nqus thauj tog rau nkoj qauv; Lub sij hawm luv luv los tiv thaiv corrosion tej yaam num (lifespan nyob rau hauv 10 xyoo) ntawm loj steel qauv (xws li Hoobkas steel kem, zoo tib yam cia tank), los yog tej yaam num uas tsis muaj peev xwm.

Core txawv:

Steel txhaj / steel xuab zeb:"kev ua tau zoo heev";garnetxuab zeb:"hnyav hauv kev tiv thaiv ib puag ncig";tooj liab slag:"tus nqi siab heev", uas sib haum rau cov kev cai sib txawv ntawm "kev xav tau siab rau qhov tseem ceeb, thaj chaw tsis zoo, thiab tus nqi qis rau qhov tsis tseem ceeb" hauv qhov project.
