Stainless hlau lauj kaub taub hau screws feem ntau txhim kho siab -kub carbon deposits, oxide nplai, thiab hlau khib nyiab los ntawm tapping/cross- txiav seams thaum kub ua hauj lwm, cuam tshuam cov khoom ua hauj lwm thiab zoo li. Cov kws tshaj lij tu cov neeg ua haujlwm, los ntawm kev tsim qauv, ua tiav kev tu kom zoo thaum tsis txhob muaj hydrogen embrittlement, corrosion, thiab dimensional hloov, ua rau nws yog ib qho tseem ceeb txheej txheem los xyuas kom meej qhov zoo ntawm stainless hlau ntawv hlau screws. Kab lus no tau txheeb xyuas tus neeg saib xyuas kev tsim cov thev naus laus zis, txheej txheem kev thov, thiab cov qauv tswj kom zoo.
Core Parameters thiab yam ntxwv ntawm Formulation Technology
Tus neeg saib xyuas siv lub citric acid + phosphoric acid composite system rau stainless coach screws. Nws yog cov kua tsis muaj xim, pob tshab nrog qhov ceev tswj ntawm 1.05 thiab 1.08 kg / L, ua raws li 1.00-1.10 kg / L specification ntau yam. Tus nqi pH yog raug kho kom haum rau 1.5-1.8, ntsuas los ntawm kev kho kom zoo ntawm cov tshuaj phosphoric acid. Cov mis no tseem nyob ruaj khov rau 6 lub hlis ntawm chav tsev kub, tsis muaj stratification lossis deterioration, kom ntseeg tau ntev.
Hais txog cov yam ntxwv ntawm kev ua haujlwm, tus neeg saib xyuas kev tu tshwj xeeb yog tsim los rau siab -kub carbon deposits thiab oxide nplai. Los ntawm cov nyhuv synergistic ntawm surfactants, inorganic acids, organic acids, corrosion inhibitors, thiab penetrants, nws ua tau zoo heev degreasing thiab oxide scale tshem tawm. Chav tsev kub immersion yog txaus kom nkag mus rau hauv kais pob qij txha thiab hla - zoo li cov seams, kom huv si tshem cov khib nyiab hlau thiab roj stains yam tsis muaj kev cia siab rau ultrasonic los yog vibratory sib tsoo. Tom qab kev kho mob, lub workpiece regains lub cim luster ntawm stainless hlau lauj kaub taub hau screws, ua ib tug tuab passivation zaj duab xis, ho txhim kho corrosion kuj. Cov txiaj ntsig tseem ceeb suav nrog: tsis muaj kev pheej hmoo ntawm hydrogen embrittlement, tsis muaj kev hloov pauv ntawm cov khoom siv kho tshuab; khaws cia qhov tseeb qhov tseeb, tsis muaj kev pheej hmoo ntawm deformation; Cov nqi khiav lag luam qis, thiab yooj yim thiab yooj yim -rau- siv cov txheej txheem.
Formulation Composition thiab Mechanism of Action
Lub formulation rau stainless cob bolts muaj xws li surfactants (txo qis interfacial nro thiab txhim khu kev nkag mus), inorganic acids (solve oxide scale), organic acids ( complex hlau ions), corrosion inhibitors (tiv thaiv substrate corrosion), penetrants (ntev huv si crevices), thiab dej (cov khoom hnyav). Cov txheej txheem sib xyaw ntawm citric acid thiab phosphoric acid sib npaug tu lub zog thiab kev nyab xeeb, tsis txhob muaj kev pheej hmoo ntawm kev xeb ntau dhau los ntawm ib qho kua qaub. Cov xim daj me ntsis tuaj yeem ua tiav los ntawm kev ntxiv 0.1% txiv qaub daj kom tau raws li cov kev xav tau zoo nkauj.
Cov txheej txheem thov thiab cov txheej txheem ua haujlwm
Cov txheej txheem tu rau stainless hlau lawj screws 212 tau muab faib ua ob txoj haujlwm: tsis yog - polishing thiab polishing.
Tsis yog - txheej txheem polishingTom ntej: Degreasing thiab tshem tawm oxide nplai → Txhuam yaug nrog dej → Cua ziab
Polishing txheej txheemDegreasing thiab tshem tawm oxide nplai → Txhuam yaug nrog dej → Polishing → Txhuam yaug nrog dej → Immersion hauv 70 ~ 90℃dej kub rau 10 vib nas this → Mechanical spin drying
Qhov pom zoo siv piv rau kev sib tsoo thiab polishing rau stainless hlau hex taub hau screws yog 15-20 kg ntawm tus neeg saib xyuas / 100 kg ntawm cov khoom. Rau cov ntaub ntawv xws li 303, 304, thiab 316, cov tshuaj ntxuav tau ncaj qha rau hauv lub tshuab sib tsoo lossis kua nplaum rau 30-60 feeb, nrog rau lub sijhawm tshwj xeeb hloov kho raws li qib ntawm oxide nplai. Rau cov ntaub ntawv xws li 667, 201, 202, 410, thiab 418, lawv yuav tsum tau hauv av kom txog rau thaum blackened ua ntej, ces 5-10 kg ntawm ntxuav tus neeg sawv cev diluted nrog 3-5 npaug ntawm cov dej ntxiv, thiab cov sib tov yog immersed rau 5-10 feeb kom txog thaum nws tig dawb. Thaum kawg, nws yog rinsed nrog dej huv rau tom ntej polishing.
Kev kho mob rau stainless hlau countersunk screws lub sij hawm yuav tsum tau kho raws li cov nyhuv tiag tiag. Immersion nyob rau hauv chav tsev kub feem ntau yuav siv sij hawm 30 feeb mus rau ob peb teev. Ultrasonic thiab kev sib tsoo kev kho mob tuaj yeem txo lub sijhawm thiab txhim kho kev ua haujlwm. Cov txheej txheem dej yaug dej yuav tsum tau muab tshem tawm kom huv si kom tshem tawm cov khoom seem uas tsis tu ncua kom tsis txhob cuam tshuam cov txheej txheem tom ntej.
Qhov sib txawv hauv kev kho rau cov khoom siv tshwj xeeb
Txawv stainless hlau vov tsev screws teb txawv rau cov neeg ua hauj lwm tu. 300 series (xws li 304 thiab 316) muaj corrosion kuj zoo heev thiab tuaj yeem ua tiav ncaj qha siv cov txheej txheem txheej txheem . 400 series stainless hlau (xws li 410 thiab 418) muaj cov ntsiab lus carbon siab, uas yooj yim tsim cov tawv nqaij oxide nplai, yuav tsum tau ua kom zoo dua qub. Duplex stainless hlau (xws li 2205) yuav tsum tau tswj xyuas lub sij hawm tu thiab concentration kom tsis txhob xaiv corrosion.
Kev Tswj Xyuas Zoo thiab Cov Qauv
Cov tshuaj ntxuav tu yuav tsum ua kom tau raws li cov ntsuas tseem ceeb xws li qhov ceev 1.00-1.10 kg / L, pH tus nqi 1.0-2.0, thiab chav tsev kub cia ruaj khov. Cov txheej txheem ntau lawm yuav tsum tau saib xyuas raw khoom purity, proportioning raug, thiab sib tov uniformity. Ua tiav stainless hlau lag screws yuav tsum dhau qhov kev ntsuam xyuas kev ruaj ntseg, kev kuaj corrosion, thiab kev kuaj xyuas cov nyhuv kom ntseeg tau tias tsis muaj hydrogen embrittlement, tsis muaj corrosion, thiab tsis muaj qhov hloov pauv.
Nyob rau hauv cov nqe lus ntawm daim ntawv thov scenarios, stainless hlau lauj kaub taub hau screws feem ntau yog siv rau kev kho kom zoo nkauj installation, yuav tsum tau high nto tiav thiab zoo huv si txheej txheem. Stainless hlau hex taub hau screws feem ntau yog siv rau siab - lub zog fastening, yuav tsum tau xyuas kom meej xov huv si los lav kev sib txuas kev ntseeg tau.
Kev txhim kho yav tom ntej yog tsom mus rau kev tsim cov qauv tsim kom zoo ib puag ncig, kev sib koom ua ke ntawm cov cuab yeej ntxuav tu ntse, thiab kev daws teeb meem. Biodegradable surfactants thiab qis -acid formulations yuav txo qhov cuam tshuam ib puag ncig; kev saib xyuas hauv online tuaj yeem kho cov txheej txheem tsis raws sijhawm; thiab cov neeg ua haujlwm tu tshwj xeeb rau cov ntaub ntawv tshwj xeeb thiab cov qauv ntawm stainless tus kheej drilling screws yuav txhim kho kev tu kom zoo thiab lub neej ua haujlwm.
