Lub Caij Nplooj Ntoos Hlav Uas Muaj Zog Zoo Dua

Cov Ntaub Ntawv Qhia Txog Lub Caij Nplooj Ntoos Hlav Uas Muaj Zog Zoo

Kev Piav Qhia Luv:

Kev siv lub caij nplooj ntoos hlav washer
1. Rau kev sib txuas ntawm cov ntsia hlau dav dav, cov ntsia hlau tiaj tiaj yuav tsum muab tso rau hauv qab lub taub hau ntsia hlau thiab lub txiv ntoo kom nce thaj chaw siab.
2. Rau cov ntsia hlau thiab cov ntsia hlau uas tsim los nrog cov kev cai tiv thaiv kev xoob, yuav tsum siv lub txiv ntoo lossis lub caij nplooj ntoos hlav ntawm lub cuab yeej tiv thaiv kev xoob, thiab lub caij nplooj ntoos hlav yuav tsum tau teeb tsa rau ntawm sab ntawm lub txiv ntoo.
3. Rau cov kev sib txuas ntawm cov ntsia hlau uas muaj cov khoom thauj hnyav lossis cov khoom tseem ceeb, cov ntaub thaiv caij nplooj ntoos hlav yuav tsum tau muab tso rau raws li qhov yuav tsum tau tsim, thiab cov ntaub thaiv caij nplooj ntoos hlav yuav tsum tau teeb tsa rau ntawm sab ntawm lub txiv ntoo.
4. Rau cov hlau I-beams thiab cov hlau channel, yuav tsum siv cov inclined washers thaum siv cov kev sib txuas inclined plane kom ua rau qhov chaw ntawm lub txiv ntoo thiab lub taub hau bolt perpendicular rau lub hau ntswj.

Cov Lus Qhia Txog Khoom

Cov Cim Npe Khoom

Cov txheej txheem kho qhov chaw

1. Ua kom dub (xiav) Cov khoom siv txuas uas yuav ua kom dub raug muab tso rau hauv lub tank kua (145 ± 5 °C) ntawm sodium hydroxide (NaOH) thiab sodium nitrite (NaNO2) oxidant kom sov thiab oxidize, yog li ntawd qhov chaw ntawm cov hlau txuas tsim cov zaj duab xis magnetic ferric tetroxide (Fe3O4) zaj duab xis, qhov tuab feem ntau yog 0.6-0.8μm, dub lossis xiav-dub. Cov qauv HG/20613-2009 thiab HG/T20634-2009 rau cov khoom siv txuas rau cov hlab siab yuav tsum tau kho xiav.

2. Phosphating phosphating yog ib qho txheej txheem ntawm cov tshuaj lom neeg thiab electrochemical reaction los tsim cov phosphate tshuaj hloov zaj duab xis, thiab cov phosphate hloov zaj duab xis tsim hu ua phosphate hloov zaj duab xis. Lub hom phiaj tseem ceeb ntawm phosphating yog los muab kev tiv thaiv rau cov hlau hauv paus thiab tiv thaiv cov hlau kom tsis txhob raug xeb rau qee qhov, los txhim kho qhov kev nplaum thiab tiv thaiv kev xeb ntawm cov xim zaj duab xis txheej ua ntej pleev xim, thiab los txo qhov kev sib txhuam thiab kev nplua hauv cov hlau txias ua haujlwm. Cov ntsia hlau loj ob chav kawg rau cov hlab siab yuav tsum tau phosphated.

3. Kub-dip galvanizing kub-dip galvanizing yog kom muab cov khoom siv hlau uas tsis muaj xeb tso rau hauv cov zinc yaj uas yaj ntawm qhov kub siab txog li 600 ° C, kom qhov chaw ntawm cov khoom siv hlau txuas nrog cov txheej zinc, thiab qhov tuab ntawm cov txheej zinc yuav tsum tsis pub tsawg dua 65μm rau cov phaj nyias hauv qab 5 hli, thiab tsis pub tsawg dua 86μm rau cov phaj tuab ntawm 5 hli thiab siab dua. Yog li ua si lub hom phiaj ntawm kev tiv thaiv xeb.

4. DacrometDacromet yog kev txhais lus thiab luv ntawm DACROMET, hu ua Dacromet, Dacromet, Dicron. Lub npe hu ua zinc-chromium txheej hauv Suav teb, nws yog ib hom tshiab ntawm cov txheej txheem tiv thaiv xeb nrog zinc hmoov, txhuas hmoov, chromic acid thiab dej deionized ua cov khoom tseem ceeb. Tsis muaj teeb meem hydrogen embrittlement thiab qhov sib xws torque-preload zoo. Txawm hais tias muaj kev txhawj xeeb txog ib puag ncig ntawm hexavalent chromium, nws yog qhov tsim nyog tshaj plaws rau cov fasteners muaj zog nrog cov kev xav tau tiv thaiv corrosion siab.
