Raws li peb paub, ntawm cov phiaj hlau ntawm phaj kub hloov pauv, titanium phaj yog qhov txawv rau kev xeb. Thiab nyob rau hauv kev xaiv ntawm gasket, viton gasket yog nto moo rau kev tiv taus rau cov kua qaub thiab alkali thiab lwm yam tshuaj. Yog li lawv tuaj yeem siv ua ke txhawm rau txhim kho cov corrosion tsis kam ntawm phaj kub hloov?
Qhov tseeb, Titanium phaj thiab cov viton gasket tsis tuaj yeem siv ua ke. Tab sis vim li cas? Nws yog lub hauv paus distenance ntawm titanium phaj uas ob yam tsis tuaj yeem siv ib txheej dense, vim tias cov txheej txheem oxide cov tshuaj pleev tau yooj yim rau cov pa Muaj ib puag ncig tom qab kev rhuav tshem. Thiab qhov no tso cai rau kev puas tsuaj thiab kho (repieldation) ntawm oxide zaj duab xis yuav tsum tau tswj hwm nyob rau hauv lub xeev ruaj khov, tiv thaiv cov titanium ntsiab hauv kev rhuav tshem kev puas tsuaj ntxiv.
Ib txwm pitting corrosion
Txawm li cas los xij, thaum titanium hlau lossis alloy nyob rau hauv ib puag ncig fluorine, raws li cov hlau titoride tawm nrog cov hlau fluoride, uas ua rau lub titanium pitting. Cov tshuaj tiv thaiv cov tshuaj tiv thaiv muaj raws li nram no:
TI2O3 + 6HF = 2TF3 + 3H2O
Ti2 + 4hf = Tif4 + 2h2o
Ti2 + 2hf = tiof2 + h2o
Cov kev tshawb fawb tau pom tias hauv cov tshuaj acidic, thaum muaj cov tshuaj fluoride rau hauv titoride ion yuav raug txo qis ntawm cov phiaj quav corrosion.
Thaum titanium hlau yam tsis muaj kev tiv thaiv ntawm titanium oxide, hauv kev muaj hydrogen ntawm hydrogen ntawm hydrogen ntawm hydrogen ntawm hydrogen ntawm hydrogen ntawm hydrogen bavrog, thiab redebe cov tshuaj tiv thaiv tshwm sim. Tom qab ntawd TIH2 yog tsim tawm ntawm Titanium Crystal saum npoo, uas nrawm dua cov corrosion, tsim cov kab nrib pleb thiab ua rau cov kab txuas nrog cua sov.
Yog li ntawd, hauv cov phaj kub ua kom sov, cov phaj vitanium thiab tsis pub nws yuav ua rau kev txhim kho hauv kev txhim kho thiab tsis ua tiav ntawm phaj sov.
Shanghai Thaum Tshav Kub Hloov Hloov Khoom Co., Ltd. Xaiv, los xyuas kom muaj kev nyab xeeb thiab txhim khu kev qha ntawm cov khoom siv.
