Dacromet Bolt Treatment Technology

Dacromet deg kev kho mob yog ib tug paub tab thiab dav txhawb ib puag ncig tus phooj ywg nto kho tshuab. Piv nrog cov txheej txheem electroplating thiab kub-dip galvanizing txheej txheem, Dacromet kev kho mob ntau dua nyob rau hauv txoj kab nrog niaj hnub ib puag ncig yuav tsum tau thiab belongs rau ib tug chromium -dawb eco-phooj ywg kev kho mob technology. Nws cov txiaj ntsig tseem ceeb yog raws li hauv qab no:

Kev tiv thaiv corrosion zoo heev: Lub thickness ntawm Dacromet txheej tsuas yog 4-8μm, tab sis nws cov kev tiv thaiv xeb yog ntau tshaj 7-10 npaug ntawm cov tsoos electroplating. Fasteners xws li hex txiv ntseej thiab cov ntxhua khaub ncaws uas kho nrog cov txheej txheem Dacromet tuaj yeem tiv taus cov tshuaj ntsev ntsev rau ntau tshaj 1200 teev yam tsis muaj xeb liab. Tsis tas li ntawd, cov xov haum raug tsis cuam tshuam, thiab cov ntsia hlau smoothness zoo ib yam nrog cov fasteners zoo tib yam.

Tsis muaj hydrogen embrittlement txaus ntshai: Qhov no yog ib qho ntawm qhov zoo tshaj plaws ntawm Dacromet, ua rau nws tshwj xeeb tshaj yog haum rau kev ua.siab - zog screws. Fasteners nrog qib zog ntawm Qib 8.8 thiab siab dua yog txhua yam siv tau. Cov txheej txheem electroplating ib txwm muaj rau hydrogen embrittlement, uas tuaj yeem ua rau siab - lub zog bolts kom tawg thaum muaj kev ntxhov siab. Hauv qhov sib piv, cov txheej txheem kev kho Dacromet tsis muaj cov tshuaj tiv thaiv hydrogen evolution thoob plaws, tshem tawm cov kev phom sij zais ntawm hydrogen embrittlement.

High-kub corrosion kuj: Qhov kub tsis kam tiv taus kub tuaj yeem ncav cuag 300 degree, thiab cov txheej txheem ua haujlwm tseem nyob ruaj khov ntawm qhov kub no. Txawm li cas los xij, zoo tib yam electroplated zinc coatings yog nquag tev thiab poob tawm thaum qhov kub txog 100 degree, ua rau tsis ua hauj lwm thiab khawb.

Muaj zog txheej adhesion thiab siab tiav: Dacromet txheej yog zoo sib xyaw nrog lub fastener substrate, featuring tsis tshua muaj zog adhesion. Nyob rau tib lub sijhawm, qhov saum npoo yog du thiab muag heev, tso cai rau cov xim thib ob ncaj qha rau ntawm txheej kom tau raws li qhov xav tau sib txawv.

Environmental friendliness thiab controllable tus nqi: Thaum lub sij hawm tag nrho cov khoom thiab txheej txheej txheem ntawm kev kho Dacromet, tsis muaj dej khib nyiab los yog cov pa khib nyiab tawm, tsuas yog ib qho me me ntawm cov khoom pov tseg. Qhov no txo ​​qhov siab ntawm peb - khib nyiab (dej, khib nyiab, khib nyiab pov tseg) kev kho mob thiab txo tus nqi kho ib puag ncig zoo piv nrog cov tshuaj electroplating.

Ua tau zoo nrog ntau qib zog: Fasteners ntawm qib sib txawv ntawm lub zog (txawm Qib 4.8, Qib 8.8, thiab lwm yam) tuaj yeem ua tiav hauv tib qhov chaw kho mob raws li kev ua kom ntseeg tau cov khoom siv sib xws thiab kev sib koom ua ke ua ntej - cov txheej txheem kho. Tsis muaj kev pheej hmoo ntawm qhov tsis muaj kev ruaj ntseg los ntawm cov khoom sib txawv.

Haum rau qib siab - qib siab - lub zog bolts: Ultra-siab - lub zog boltsQib 12.9 kuj tuaj yeem kho nrog Dacromet. Tom qab kev kho mob, cov xov haum yog du. Qhov kev ua tau zoo sib xws ntawm tus qauv Dacromet bolts thiab txiv ntseej yog zoo ib yam nrog cov fasteners zoo tib yam, tshem tawm qhov xav tau ntawm cov txiv ntoo reaming thiab tsis cuam tshuam rau kev sib dhos ua haujlwm.

Haum rau me me - loj hex qhov (socket head cap screws): Vim lawv cov qauv tshwj xeeb, me me - loj hex socket taub hau hau hau screws yog qhov ua rau deformation ntawm hex qhov (socket), txo lub zog, thiab tsis muaj peev xwm lav qhov tseeb qhov tseeb thaum kub -dip galvanizing. Nyob rau hauv sib piv, kev kho Dacromet yog nqa tawm ntawm qhov kub thiab txias (feem ntau nyob ib ncig ntawm 200 degree), uas yuav tsis txo qhov loj ntawm hex qhov (socket) qhov opposite sab los yog puas cov xov raug. Thaum lub sij hawm sib sau ua ke, tus ciaj ntswj haum zoo, tag nrho daws cov teeb meem tiv thaiv corrosion ntawm me me - loj hex lub taub hau hau hau screws thiab ua rau nws qhov zoo tshaj plaws tiv thaiv corrosion rau cov khoom zoo li no.

Daim ntawv thov ntawm Dacromet Screw Technology hauv Hnyav-Kev Lag Luam Tsheb Tsheb

Ua tau raws li qhov kev thov rau siab - lub zog fasteners: Ib qho ntawm qhov sib txawv ntawm Dacromet thiab kub -dip galvanizing yog qhov tsis muaj hydrogen embrittlement txaus ntshai. Ntau lub siab- lub zog screws yog siv rau hauv qhov tseem ceeb ntawm cov tsheb hnyav- cov tsheb thauj khoom (xws li lub chassis thiab lub cav qhov chaw), thiab cov ntsia hlau zoo li no tsis tshua muaj siab rau hydrogen embrittlement. Yog li ntawd, kev kho Dacromet tau dhau los ua qhov kev xaiv tseem ceeb- nws tsis tsuas yog ua kom muaj kev tiv thaiv corrosion zoo heev tab sis kuj zam kev puas tsuaj los ntawm hydrogen embrittlement, tiv thaiv kev nyab xeeb ntawm kev tsav tsheb.

Kev ntsuas kev tiv thaiv xeb thiab qhov yuav tsum tau ua kom pom: Kub-dip galvanized txheej yog ua rau zinc nodules thiab burrs, ua rau tsis zoo. Nyob rau hauv sib piv, Dacromet txheej yog ib yam, ilv, thiab zoo huv si nyob rau hauv tsos. Yog li ntawd, rau cov khoom siv hauv tsheb tau teeb tsa hauv tsev uas yuav tsum muaj kev tiv thaiv xeb zoo thiab zoo nkauj zoo nkauj (xws li cov khoom siv sab hauv thiab cov cab txuas txuas),Dacromet Boltyog siv ntau dua.

Kev kho kom haum rau nyias- txheej txheej yuav tsum tau ua: Dacromet txheej yog nyias, yog li nws yuav tsis cuam tshuam rau kev sib dhos clearance ntawm precision qhov chaw vim txheej thickness, ua rau nws tshwj xeeb tshaj yog haum rau fastening scenarios ntawm ntau yam precision khoom ntawm cov tsheb thauj khoom. Nyob rau tib lub sijhawm, qhov chaw qhuav hauv tsev ntawm cov tsheb thauj khoom nrog ob peb cov xov xwm corrosive yog qhov chaw zoo tshaj plaws rau Dacromet screws. Yog li ntawd, lawv muaj ntau yam kev thov nyob rau hauv hnyav- kev lag luam tsheb thauj khoom, thiab cov saum toj no tsuas yog cov xwm txheej nkaus xwb.
