Sei zinc plating isingakurudzirwe kune yakakwirira-simba mabhaudhi? Uye ndedzipi dzimwe nzira dzinogona kushandiswa panzvimbo pezvo? Kudzivirira mabhaudhi uye screws kubva mukuora pasina kukanganisa simba kana kuchengeteka.

Apo mainjiniya anotsanangura mabhaudhi akasimba (Giredhi 10.9, 12.9, kana yakaenzana neASTM A325/A490) yekubatanidza zvimiro, vanotarisira kukwirisa-kuremerwa kuita. Asi kana kuchengetedzwa kwecorrosion kuchidikanwa zvakare, iyo yekusarudzika instinct inowanzo tsanangura zinc galvanizing. Sarudzo iyoyo inogona kuva nengozi.

Dambudziko chiitiko chinonzi hydrogen embrittlement - chinyararire kutadza modhi iyo inogona kukonzera mabhaudhi kuputsika pasina yambiro, mazuva kana kunyange mavhiki mushure mekuiswa. Hezvino izvo zvaunoda kuziva, uye izvo anti-corrosion solutions dzakachengeteka kune yakakwirira-tensile fasteners.

Iyo Yakavanzika Ngozi: Hydrogen Embrittlement

Munguva ye electroplating process, atomic hydrogen inogadzirwa sechigadzirwa. Kana mabhaudhi ane simba rekusimba riri pamusoro pe1,000 MPa (kuoma> 320 HV) achipinza haidhirojeni iyi murutanda rwesimbi, mhedzisiro inorasika. Iyo bhaudhi inogona kupasa ese emhando yekuongorora, torque nenzira kwayo pane saiti, uyezve kukundikana kamwe kamwe pasi pemazuva ose mutoro.

Uku kunonoka kutadza - ne zero deformation yepurasitiki uye pasina yambiro inooneka - inoita kuti hydrogen embrittlement ive imwe yenjodzi dzakanyanya muhuinjiniya hwezvimiro. For socket head cap screws, hex mabhaudhi, uye mamwe magiredhi epamusoro fasteners inoshandiswa mukuchengetedza-yakakosha maapplication (mabhiriji, mhepo turbines, kumiswa kwemotokari), mhedzisiro inogona kuve yakashata.

Chinhu Chakakosha: Kunyangwe post-plating kubika (hydrogen embrittlement relief) haigone kuvimbisa kubviswa kwakazara kwehydrogen muGiredhi 10.9 uye 12.9 mabhaudhi. Ngozi haimbodonhe kusvika zero.

Galvanizing Risk neBolt Giredhi

Bolt Giredhi	Tensile Simba	HE Ngozi	Kurudziro
8.8	800 MPa	Low	Galvanizing inogamuchirwa
10.9	1,000 MPa	High	Shandisa zinc flake coating
12.9	1,200 MPa	Critical	Zinc flake kana simbi isina tsvina

Kupisa-dip galvanizing kunotakura njodzi yakaderera yehydrogen pane electroplating, asi iyo acid pickling isati yarapwa ichiri kuunza hydrogen. Nezvekuchengetedzwa kwepamusoro-soro, haisiriyo sarudzo yakanaka.

Safe Anti-Corrosion Alternatives

Saka unodzivirira sei mabhaudhi akasimba uye screws kubva ngura kana galvanizing iri kubva patafura? Hedzinoi dzimwe nzira dzakasimbiswa:

Zinc Flake Coating (Dacromet / Geomet)

Inoshandiswa nemichina - hapana kugeza asidi, hapana electrolysis, zero hydrogen chizvarwa. Inoendesa 600-1,000+ maawa emunyu wekupfapfaidza kuramba. Yakanakira Grade 10.9 uye 12.9 mabhaudhi, screws, uye studs.

Best Sarudzo

Mechanical Zinc Plating

Cold-welds zinc particles panzvimbo yefastener pasina magetsi. Hapana njodzi yehydrogen, yakakodzera kune yakakwirira-tensile hex mabhaudhi uye nzungu.

Hapana Hydrogen Ngozi

Stainless Steel Fasteners

A316 kana A4 (316) mabhaudhi esimbi isina tsvina uye screws zvinopa inherent corrosion resistance. Yakanakira marine, makemikari, uye kunze nharaunda.

Premium Solution

PTFE / Fluoropolymer Coating

Inopa yakanakisa makemikari kuramba uye yakaderera friction. Kazhinji inosanganiswa ne zinc underlayer yekunatsiridza corrosion dziviriro pazvimisikidzo zveindasitiri.

Specialty Use

Kusarudza Mhinduro Yakarurama

Pakusarudza an anti-corrosion treatment zvako fasteners, funga zvinhu izvi:

Bolt Giredhi— Grade 8.8 zvichidzika vanogona kushandisa galvanizing. Kune 10.9 uye pamusoro, nguva dzose sarudza zinc flake kana simbi isina tsvina.
Environment- Mamiriro ekunze emugungwa nemaindasitiri anoda nguva yakakwira yekupfapfaidza munyu. Geomet kupfekauye mabhaudhi esimbi asina tsvina pfuura apa.
Application-Mota, simba remhepo, uye zvimiro zvesimbi zvekubatanidza zvinoda zero hydrogen njodzi. Mechanical plating uye zinc flake masisitimu ndiwo akajairwa.
Mutengo maringe nekuita-Zinc flake coatings (Dacromet, Geomet) inopa yakanakisa chiyero chekudzivirira kutu, hydrogen kuchengetedza, uye mutengo wevazhinji heavy-duty fastenerapplications.

Izvi Zvinorevei Kutenga

Kune zvikwata zvekutsvaga uye mainjiniya eprojekiti, kutora kwakajeka: usambofa wakamira kune galvanizing kune yakakwirira-simba fasteners. Gara uchitsanangura iyo bhaudhi giredhi uye corrosion nharaunda, uye shanda neyako fastener mugadziri kusarudza nzira yekuputira inobvisa hydrogen embrittlement njodzi.

At FUJINRUI, tinogadzira anti-corrosion bolts, screws,uye tsika fasteners neDacromet, Geomet, mechanical zinc, uye PTFE machira - akarongedzerwa kune yako application uye zvakatipoteredza zvinodiwa. Batch yega yega inoedzwa kune ese mekiniki simba uye corrosion kuramba isati yatumirwa.
