Yuav Ua Li Cas Xaiv Los Ntawm Ntau Qib Ntawm Titanium hauv Kev Lag Luam Tshuaj?

Qhov zoo ntawm "corrosion resistance + lightweight" rau txhua qib yog dav siv hauv kev lag luam tshuaj.Titanium thiab titanium alloys tuaj yeem hloov cov hlau tsis huv, Hastelloy alloy, thiab lwm yam, txuas ntxiv lub neej kev pab cuam ntawm cov khoom siv tshuaj, txo cov nqi tu, thiab tsis txhob muaj kev sib kis nruab nrab.

 

I. Lub Pyramid ntawm Titanium cov ntaub ntawv

Cov no yog cov qib sib txawv ntawm cov khoom siv titanium, uas yog siv rau hauv kev lag luam tshuaj. Raws li Kev Ua Haujlwm thiab tus nqi, peb tuaj yeem ua qhov kev tshuaj xyuas pyramid los sib piv qhov sib txawv ntawm lawv.

 

 

 

II. Core Chemical Application Scenarios

 

• Qib 1

Kev kho mob ntawm corrosive media uas tsis tshua muaj siab thiab siab purity yuav tsum

Nyias-cov hlab ntsha phab ntsa, cov kav dej nqus (kev thauj cov kua qaub, cov tshuaj alkaline)

Liners rau cia tank ntawm siab- purity tshuaj raw khoom (xws li, hluav taws xob- qib tshuaj)

Precision kuaj cov tshuaj tiv thaiv cov cuab yeej, cov khoom siv hluav taws xob me me

Ultra- cov ntsiab lus tsis muaj impurity tsawg, zoo ductility rau vuam thiab sib sau yooj yim

 

• Qib 2 → Feem ntau siv

General corrosive ua hauj lwm tej yam kev mob (tsis muaj huab cua kub / siab)

Reactors, agitators, kub exchangers (qhov tsis kam ntawm feem ntau cov organic / inorganic acids xws li sulfuric acid, hydrochloric acid, nitric acid, acetic acid)

Chemical pipelines, li qub, flanges (transporting brine, dej phwj tuaj, corrosive gases)

Chlor{0}}alkali kev lag luam: Brine purification khoom, electrolyzer auxiliary Cheebtsam

Cov khoom siv tshuaj tua kab thiab zas xim (tiv taus rau ntau-cov khoom siv corrosive media)

ruaj khov corrosion kuj, nruab nrab nqi ua, loj ntau lawm feasibility. Nws yog haum rau ntau tshaj 80% ntawm cov pa tshuaj scenarios.

• Qib 3

Siab thiab nruab nrab siab corrosive ua haujlwm ib puag ncig.

Siab - cov kav dej siab (siv los thauj cov roj corrosive xws li chlorine, ammonia)

Siab - siab reactor plhaub, lub cev twj tso kua mis, impellers (nrog siab thiab tiv thaiv corrosion)

Chemical mechanical kis tau tus mob (shafts, txuas rods, ob lub zog thiab corrosion kuj)

Lub zog siab dua li titanium ntshiab, tsis yooj yim rau distorted nyob rau hauv siab load, corrosion kuj tsis inferior rau Gr1 / Gr2

 

• Qib 7 → Qib tshwj xeeb rau Cov Xov Xwm Loj Corrosive

Muaj zog txo acids, hnyav corrosion ib puag ncig

Hydrochloric acid synthesis towers, sulfuric acid concentration khoom, acetic acid distillation yees (tiv cov concentrated acid corrosion)

chlorine- muaj cov khoom nruab nrab (sodium hypochlorite ntau lawm cov cuab yeej, chloroacetic acid synthesis reactors)

Kev kho cov dej khib nyiab (high-concentration acid-puag dej khib nyiab, hnyav hlau ion- muaj cov dej khib nyiab)

Pharmaceutical Industry: Synthesis of pharmaceutical intermediates

Tom qab ntxiv palladium (Pd), qhov tsis kam rau pitting corrosion thiab crevice corrosion yog qhov zoo tshaj rau cov ntshiab titanium, ua rau nws yog "kev xaiv zoo tshaj" rau kev tuav kom txo tau cov xov xwm corrosive.

 

• Qib 12 → Qib tshwj xeeb rau kev sib xyaw ua ke siab - Kub + Corrosion ua haujlwm

Coexisting ib puag ncig ntawm kub kub + corrosion

Reactors, steam heat exchangers (Kev kho mob siab -kub organic acids, kub alkaline daws)

Petrochemical kev lag luam: Catalytic cracking units, hydrofining khoom (tiv siab -kub hydrogen sulfide thiab carbon dioxide corrosion)

Chav kav dej, siab -kub corrosive gas kis pipelines

Papermaking kev lag luam: Pulp bleaching khoom (tiv taus rau cov tshuaj chlorine-raws li cov tshuaj bleaching + siab- qhov kub thiab txias)

 

Alloying nrog molybdenum (Mo) + npib tsib xee (Ni) tuaj yeem ua tiav ob qho tib si siab - kub tsis kam thiab corrosion kuj, nrog lub zog siab dua li cov ntshiab titanium. Nws yog haum rau siab -kub tshuaj tiv thaiv txheej txheem hauv kev lag luam tshuaj

III. Cov lus qhia siv tshuaj

Pa corrosion, cov xwm txheej dav dav → Ua Ntej Qib 2 (qhov sib npaug ntawm tus nqi + kev ua haujlwm);

High purity, nyias -cov khoom siv phab ntsa → Qib 1

Nruab nrab thiab siab -kev ua haujlwm siab → Qib 3

Muaj zog txo cov kua qaub (hydrochloric acid, sulfuric acid) → Qib 7

Kub kub + corrosion → Qib 12
