1. Hordhac Dacromet Hex Bolts

Dacromet hexagon bolts waxay u taagan yihiin fasalka waxqabadka sare leh ee xirayaasha loogu talagalay iska caabinta daxalka ee gaarka ah iyo ka hortagga miridhku muddada dheer. Dhalooyinkani waxay isku daraan isku halaynta farsamada ee boolal-madaxa caadiga ah ee laba geesoodka leh iyo daahan heersare ah oo zinc-aluminium ah oo loo yaqaan Dacromet (sidoo kale loo yaqaan Dacro ama dahaarka zinc-flake). Natiijadu waa boodhka soo saara waxqabadka ka hortagga daxalka ee jawiga adag iyadoo la ilaalinayo joomatari dunta saxda ah iyo xoogga xajinta sare.

Si ka duwan dhalooyinka galvanized ee caadiga ah ee korantada-galvanized ama kulul-muquufinta, Dacromet bolts hexagon waxay isticmaalaan hannaan daahan aan koronto lahayn. Tani waxay meesha ka saaraysaa halista isku-soo-baxa haydaroojin-faa'iido muhiim ah oo loogu talagalay boolal-xoog-sare ee darajooyinka 8.8, 10.9, iyo 12.9. Filimka Dacromet ee khafiifka ah, lebbiska ah (sida caadiga ah 4-12 μm) wuxuu bixiyaa caabbinta milixda-buufinta sare, caabbinta kulaylka, iyo adkaysiga guud ee ka-hortagga miridhku, taas oo ka dhigaysa boolalyadan doorashada la doorbidayo ee baabuurta, dhismaha, tamarta dabaysha, badda, iyo codsiyada qalabka warshadaha.

2. Waa maxay Dakrometka

Dacromet waa tignoolajiyada daawaynta birta ku salaysan ee aan organic, biyaha ku salaysan oo ka kooban ugu horrayn ka samaysan jeexjeexyada zinc aadka u fiican, jajabka aluminiumka, iyo xidhayaasha chromium-ku salaysan. Marka lagu dabaqo bolt hexagon oo lagu daaweeyo heerkul sare (qiyaastii 300 °C), jajabyadu waxay la jaanqaadaan lakabyo badan oo is dulsaaran, samaynta caqabad cufan, bir ah oo qalin-cawl ah. Qaab dhismeedkan lakabka badan ayaa abuuraya labadaba caqabad jireed oo ka soo horjeeda qoyaanka iyo elektrolytka iyo habka ilaalinta anodic-ka allabari oo si firfircoon uga hortagaya sameynta miridhku.

Dahaarka ku yaala dacromet hexagon bolt wuxuu bixiyaa laba difaac: jajabyada zinc waxay u dhaqmaan sidii anode allabari, oo si doorbidan u ilaaliya substrate-ka birta, halka jajabyada aluminiumka iyo matrixka aan organic ahayn ay kor u qaadaan sifooyinka xannibaadda waxayna hagaajiyaan caabbinta guud ee daxalka. Sababtoo ah geeddi-socodku waa non-electrolytic, ma jiraan wax hydrogen ah oo lagu soo bandhigo xargaha birta, ilaalinta sharafta buuxda ee farsamada ee boolal-xoog badan.

3. Habka dahaarka Dacromet ee loogu talagalay Bolts Hexagon

Soo saarista bolt hexagon Dacromet ah oo la isku halayn karo waxay raacdaa taxane si taxadar leh loo xakameeyay oo loogu talagalay in lagu kordhiyo ku dheggan, lebbiska, iyo waxqabadka ka-hortagga daxalka:

1. Diyaarinta dusha sare: Boolku waxa uu maraa nadiifin dhamaystiran iyo ka saarida makaanikada ama alkaline. Khudaarta aysiidhka si ula kac ah ayaa looga fogaadaa si looga hortago nuugista hydrogen taas oo keeni karta in ay dillaacaan boolal awood sare leh.

2.Coating Coating: Dhalooyinka saddex geesoodka ah ee la nadiifiyay ayaa la dhex geliyaa, lagu buufiyaa, ama lagu dhex miiqayaa biyo ku salaysan Dacromet slurry oo ay ku jiraan jajabyo zinc iyo aluminium ah. Dip-spin waa habka wershadaha ee ugu badan ee habaynta boolalyada.

3.Curing / Sintering: Daboolka dahaarka leh ayaa lagu dubay qiyaastii 300 ° C. Inta lagu jiro daawaynta binder-ku waxa uu falcelinayaa oo jajabka macdanaha ah waxa uu noqdaa filim aan dabiici ahayn oo joogto ah oo si adag ugu dheggan.

4.Baaritaanka Tayada: Dacromet hexagon boolal la dhammeeyay waxaa laga hubiyaa dhumucda dahaarka, ku dheggan, muuqaalka, iyo buufinta milixda si loo dammaanad qaado ilaalinta ka hortagga miridhku joogto ah.

4. Isbarbardhigga Waxqabadka Dahaarka Ka-hortagga Daxalka

7. Gabagabo

Dacromet hexagon bolts ayaa bixiya xal casri ah, wax qabad sare leh oo loogu talagalay codsiyada u baahan labadaba xoog farsamo oo sarreeya iyo caabbinta daxalka ee muddada dheer. Marka la isku daro dahaarka khafiifka ah ee zinc-aluminiumka ah ee khafiifka ah ee aan elektrolytka ahayn ee leh joomatari laba geesood ah oo sax ah, boolashani waxay meesha ka saarayaan khataraha isku xidhka hydrogen-ka iyagoo keenaya iska caabin milix-saydh ah oo aad uga sarreeya koronto-galvanization-ka caadiga ah. Iska caabbinta kulaylkooda aadka u wanaagsan, iswaafajinta dunta, iyo saaxiibtinimada deegaanka ayaa sii kordhinaysa qiimahooda guud ahaan baabuurta, tamarta, dhismaha, iyo qaybaha warshadaha.

Marka la tilmaamayo xidhayaasha deegaanka adeega daxalka ah, injineerada iyo iibsadayaashu waxay si isa soo taraysa ugu jeestaan dahaarka Dacromet-dahaarka leh ee bolts-ka ah ee la isku halayn karo, doorashada ka hortagga miridhku kaas oo ilaaliya kala-goysyada muhiimka ah tobanaan sano. Xakamaynta habka saxda ah iyo xaqiijinta tayada waxay hubisaa in boodh kastaa uu keeno waxqabadka ilaalinta daxalka ee buuxa ee farsamada Dacromet loo yaqaan.

Isku soo wada duuboo, bolt hexagon-ka Dacromet wuxuu u taagan yahay sidii la xaqiijiyay, kharash-ku-ool ah, iyo farsamo ahaan ka-hortagga daxalka ee codsiyada ugu baahida badan.

Horay Xiga.
