Kev siv ntawm lub tshuab ntxhua khaub ncaws tiaj tus

1. Lub luag haujlwm thiab cov yam ntxwv ntawm cov lev tiaj tus
Lub gasket tiaj tiaj, tseem hu ua lub gasket tiaj tiaj lossis lub gasket tiaj tiaj, yog ib hom gasket uas muaj cov duab zoo li lub phaj tiaj tiaj, feem ntau siv ua lub gasket ntawm qhov txuas ntawm cov fasteners. Nws lub luag haujlwm yog los faib lub zog nruj ntawm cov connectors, nce thaj chaw sib cuag, thiab txo qhov xoob lossis qaug zog puas tsuaj los ntawm hydrophobicity, thaum tiv thaiv tau zoo dej, roj, thiab roj to. Cov khoom siv ntawm lub tiaj tiaj feem ntau yog hlau lossis roj hmab, uas muaj cov yam ntxwv ntawm kev tiv taus kub siab, siab siab, thiab hnav tsis kam.

2. Cov xwm txheej siv thiab kev ceev faj rau cov khoom
Feem ntau cov gaskets tiaj tiaj yog siv los txuas cov fasteners xws li impellers, yeeb nkab, lub luj tshib, flanges, thiab lwm yam kom ntseeg tau tias muaj kev nruj thiab kev sib khi ntawm cov connectors. Thaum siv, nws yog ib qho tsim nyog los xaiv cov khoom siv thiab tuab raws li qhov siab, kub, thiab lwm yam ntawm cov khoom siv kom ntseeg tau tias nws siv tau ib txwm.

3. Thaum siv, yuav tsum ua raws li qhov yuav tsum tau ua thiab kev siv, thiab nws yuav tsum tsis txhob nruj dhau lossis xoob dhau kom tsis txhob muaj kev puas tsuaj lossis xoob, uas yuav ua rau muaj kev phom sij.
Hauv kev xaus, cov ntxhua khaub ncaws tiaj tus thiab cov ntxhua khaub ncaws yog ob lub gaskets siv ntau hauv kev sib txuas ntawm cov khoom siv kho tshuab, thiab lawv cov duab sib txawv thiab qhov ntau thiab tsawg muab rau lawv cov xwm txheej siv tshwj xeeb thiab cov yam ntxwv. Thaum xaiv thiab siv, kev xaiv thiab kev siv uas tsim nyog thiab siv tau raws li qhov xwm txheej tiag tiag.

Cov txheej txheem kho qhov chaw

1. Electro-galvanizingElectro-galvanizing, tseem hu ua txias galvanizing hauv kev lag luam, yog cov txheej txheem ntawm kev siv electrolysis los tsim cov hlau sib npaug, ntom thiab zoo-bonded lossis alloy deposition txheej rau ntawm qhov chaw ntawm lub workpiece. Piv nrog rau lwm cov hlau, zinc yog ib qho pheej yig thiab yooj yim rau txheej hlau, uas yog ib tug nqi qis tiv thaiv corrosion electroplating txheej, uas yog dav siv los tiv thaiv cov hlau qhov chaw, tshwj xeeb tshaj yog tiv thaiv atmospheric corrosion, thiab rau kho kom zoo nkauj. Plating technologies suav nrog channel plating (lossis dai plating), barrel plating (rau cov khoom me me), xiav plating, tsis siv neeg plating, thiab txuas ntxiv plating (rau hlau, strip). Electrogalvanizing yog cov txheej txheem feem ntau siv rau cov fasteners lag luam. Nws pheej yig dua thiab muaj qhov zoo dua, thiab tuaj yeem muaj nyob rau hauv dub lossis tub rog ntsuab. Txawm li cas los xij, nws cov kev ua tau zoo tiv thaiv corrosion yog qhov nruab nrab, thiab nws cov kev ua tau zoo tiv thaiv corrosion yog qhov qis tshaj plaws ntawm cov zinc plating (txheej txheem) txheej. Feem ntau, qhov kev sim tshuaj tsuag ntsev nruab nrab ntawm electrogalvanizing yog nyob rau hauv 72 teev, thiab cov neeg sawv cev sealing tshwj xeeb kuj siv los ua kom qhov kev sim tshuaj tsuag ntsev nruab nrab ncav cuag ntau dua 200 teev, tab sis tus nqi kim, uas yog 5-8 npaug ntawm kev galvanizing dav dav. Cov khoom siv rau cov khoom siv feem ntau muaj xim zinc thiab dawb zinc, xws li 8.8 thiab lwm yam bolts qib lag luam.

2. Chrome plating feem ntau yog los txhim kho qhov tawv ntawm qhov chaw, zoo nkauj thiab tsis xeb. Chromium plating muaj kev ruaj khov tshuaj zoo thiab tsis ua haujlwm hauv alkalis, sulfides, nitric acid thiab feem ntau cov organic acids, tab sis nws yaj tau hauv hydrohalic acid (xws li hydrochloric acid) thiab kub sulfuric acid. Vim tias chromium tsis hloov xim, nws tuaj yeem tswj nws lub peev xwm reflective ntev thaum siv, thiab zoo dua li nyiaj thiab nickel.

3. Nickel plating feem ntau yog muab faib ua cov txheej txheem hnav-resistant, tiv thaiv corrosion, tiv thaiv xeb, thiab feem ntau nyias txheej txheem
