Yuav ua li cas paub qhov txawv ntawm stainless hlau bolts, galvanized thiab nickel plated bolts rau hluav taws xob cua sov kav

Yuav ua li cas paub qhov txawv ntawm stainless hlau bolts, galvanized thiab nickel plated bolts rau hluav taws xob cua sov kav

Ua ntej, nws yog txiav txim los ntawm cov xim - stainless hlau yog xim hlau xim hlau, galvanized screws yog dawb, xim, los yog dub, thiab npib tsib xee plated screws yog nyiaj.

1. Stainless hlau screws yog ua los ntawm stainless hlau, thiab cov xim ntawm stainless hlau yog tsuas yog ib tug alloy ntawm hlau thiab carbon, yog li cov xim yog ze rau cov hlau;

2. Qhov saum npoo ntawm galvanized screws yog coated nrog dawb zinc, xim zinc, dub zinc, thiab lwm yam, yog li cov xim ntawm galvanized screws feem ntau yog dawb, xim, lossis xim dub;

3. Cov xim ntawm npib tsib xee plated screws muaj feem xyuam rau npib tsib xee, feem ntau qhia txog cov xim nyiaj ci heev.

Lwm txoj hauv kev kom paub qhov txawv ntawm stainless hlau screws, galvanized thiab nickel plated screws

1. Siv cov hlau nplaum kom paub qhov txawv

Stainless hlau feem ntau tsis muaj hlau nplaum, thiab dab tsi tuaj yeem nyiam los ntawm cov hlau nplaum yog stainless hlau screws. Galvanized thiab nickel plated screws tuaj yeem nyiam los ntawm cov hlau nplaum;

2. Siv cov tshuaj tiv thaiv oxidation kom paub qhov txawv

Hlau nickel muaj zog passivation muaj peev xwm. Thaum lub sij hawm electroplating txheej txheem, nws tuaj yeem hloov pauv sai sai rau hauv ib txheej nyias ntawm passivation ntawm qhov chaw. Yog li ntawd, muaj ib tug passivation zaj duab xis nyob rau saum npoo ntawm npib tsib xee plated screws, thiab ib txheej ntawm zinc ntawm galvanized nto. Tsis muaj ib yam dab tsi ntawm cov hlau tsis huv, uas tuaj yeem ua rau muaj zog oxidant;

3. Sib txawv nrog cov acids muaj zog thiab cov hauv paus

Stainless hlau muaj chromium thiab npib tsib xee, uas muaj zog corrosion kuj thiab tsis corroded los ntawm muaj zog acids los yog alkalis. Muaj ib zaj duab xis passivation rau ntawm cov nickel plated screws, uas corrode maj mam los ntawm cov kua qaub los yog alkalis, thaum galvanized screws corrode sai.

Cov ntsiab lus

Cov txheej txheem ntawm kev paub qhov txawv ntawm stainless hlau screws, galvanized thiab nickel plated screws los ntawm lawv cov tsos yog saib cov xim ntawm cov ntsia hlau. Cov xim ntawm stainless hlau screws yog ze rau cov xim hlau ntawm cov hlau, thaum galvanized screws yog dawb, xim, thiab dub, thiab npib tsib xee plated screws yog nyiaj ci heev. Tsis tas li ntawd, cov hlau nplaum, cov tshuaj tiv thaiv oxidation, thiab muaj zog acids thiab alkalis tuaj yeem siv los ua kom paub qhov txawv ntawm stainless hlau screws, galvanized thiab nickel plated screws.
