Thin, Uniform Coating e tsamaellana le Precision Threads

Botenya bo tloaelehileng ba filimi ea Dacromet ea 5–12 µm bo tšesaane haholo ho feta hot-dip galvanizing (hangata 50–80 µm). Ka lebaka leo, mapheo a likhoele le li-root radii li lula li le boemong bo nepahetseng, ho lumella linate tse tloaelehileng hore li kopane hantle ntle le tlhoko ea lipompo tse kholo kapa litsiane tse lefelloang. Ho roala ho boetse ho kenella ka hare, li-fillets tse ka tlas'a hlooho, le flange e ka tlas'a hlooho ea bolt, e fana ka tšireletso e tsoelang pele e thibelang kutu moo ho pota-pota ho tloaelehileng ho ka siea libaka tse tšesaane kapa tse nang le masoba.

Thermal Stability le Mechanical Durability

Ho roala ho bonts'a ho khomarela hantle, ho hanyetsa ha abrasion nakong ea ho ts'oaroa le ho kenya, le lubricity e laoloang e tlatsetsang likamanong tse tsitsitseng tsa torque-tension-haholo-holo tsa bohlokoa bakeng sa likopano tsa bolt ea flange moo ho kenngoa ha junifomo ho bohlokoa.

Boikamahanyo ba Tikoloho le Taolo

Joalo ka sistimi e thehiloeng metsing e se nang cadmium, lead, le (ka litlhophiso tsa sejoale-joale) matšoenyeho a hexavalent chromium ha e laoloa hantle, Dacromet e ts'ehetsa ho lateloa ha litaelo tsa RoHS, REACH, le ELV. Ts'ebetso e hlahisa litšila tse fokolang tse kotsi ha li bapisoa le melapo ea setso ea electroplating, e tsamaisanang le litlhoko tsa sejoale-joale tsa ts'ebetso bakeng sa li-fasteners tsa indasteri.

Libaka tsa Kopo ea Mantlha bakeng sa Dacromet Flange Bolts

Motsoako o ikhethang oa ts'epo e phahameng ea clamping le ts'ebetso ea nako e telele e khahlanong le mafome e etsa hore Dacromet flange bolts e be khetho e ratoang liindastering tse ngata:

Mehopolo ea Khetho le Tiisetso ea Boleng

Ho hlalosa li-bolts tsa Dacromet flange ho hloka tlhokomelo ho lintlha tse 'maloa tse sebetsang. Botenya ba ho roala le sebopeho (mohlala, letoto la Dacromet 320 khahlano le Dacromet 500) li lokela ho tsamaisana le sehlopha se lebelletsoeng sa ho bola le coefficient e hlokahalang ea likhohlano. Bakeng sa lits'ebetso tsa meralo, thepa ea motheo ea bolt le sehlopha sa thepa se tlameha ho khotsofatsa litekanyetso tse nepahetseng tsa ASTM, ISO, kapa EN, athe Dacromet finish ka boeona e lokela ho sebelisoa ke processor e nang le laesense kapa e nang le litsebo tse nang le bokhoni ba ho etsa dip-spin kapa deposition e sa fetoheng le pheko e laoloang.

Netefatso ea boleng hangata e kenyelletsa tlhahlobo ea pono bakeng sa chebahalo e tšoanang ea silevera-grey, tlhahlobo ea ho khomarela, tekanyo ea botenya ba ho penta, le tlhahlobo ea setlolo sa letsoai kapa ea cyclic corrosion disampole tsa tlhahiso. Ha bolt ea flange e koahetsoeng e reretsoe ho sebelisoa le linate tse koahetsoeng ka Dacromet, litšobotsi tsa torque-tension li lula li le teng esale pele; ho kopanya le li-finishing tse sa tšoaneng (mohlala, linate tse nang le zinki) li ka fetola khohlano 'me li lokela ho qojoa ntle le haeba li tiisitsoe ke tlhahlobo e kopanetsoeng.
