GEOMET® (Jumete) Dahaarka leh Bolts-Hexagonal-hordhac Farsamo 

1. Hordhac GEOMET® (久美特) Dahaarka

GEOMET® (caadi ahaan loo yaqaan Shiineeska sida 久美特 ama Jumete) waa chromium-free, daahan ka sameysan zinc-aluminium oo biyo ku saleysan oo ay soo saartay NOF Metal Coatings Group sidii ku guulaysta deegaanka saaxiibtinimo ee habka caadiga ah ee DACROMET®. Waxay siisaa ilaalin heer sare ah oo daxalka ah xirmooyinka birta, gaar ahaan boolal lix geesood ah, iyadoo si buuxda u raacaysa xeerarka deegaanka ee casriga ah sida RoHS, REACH, ELV (2000/53/EC), iyo ISO 10683.

Dahaarku waxa uu ka kooban yahay jeexjeexyada Zinc iyo aluminium ee ku xidhan matrix aan organic ahayn. Codsaday hababka lagu buufiyo ama lagu buufiyo oo lagu daaweeyay heerkul aad u hooseeya, GEOMET® waxay samaysaa filim khafiif ah oo bir ah oo qalin ah (sida caadiga ah 6-12 μm) kaas oo aan si weyn u saamaynaynin cabbirka dunta ama taam. Sababtoo ah geeddi-socodku waa non-electrolytic, waxay si buuxda u baabi'inaysaa khatarta hydrogen ebrittlement-faa'iido muhiim ah oo loogu talagalay boolal-xoog badan (fasalada hantida 8.8, 10.9 iyo 12.9).

1.1 Faa'iidooyinka muhiimka ah ee GEOMET®

• Si buuxda chromium-free (ma jiraan Cr⁶ ama Cr³⁺) iyo biyo ku salaysan - wax soo saarka deegaanka mas'uul ka ah.
• Iska caabin milix-buufin heer sare ah: 720-1500+ saacadood (ISO 9227 / ASTM B117) waxay kuxirantahay darajada iyo dhumucda
• Ma jiro qallal hydrogen ah - oo ku habboon xirmooyinka cufan ee sarreeya.
• Filimka khafiifka ah (≈ 8 μm celceliska) - kuma faragalin isku-ururinta bolt-nut ama qiyamka qulqulka.
• Dejinta kulaylka wanaagsan ilaa 300 °C iyo iska caabbinta dareeraha baabuurta, dareerayaasha iyo daxalka meertada.
• Korantada korantada iyo iswaafajinta bimetallic ee aluminium.
• Waxaa ansixiyay OEM-yada waaweyn: Toyota, Honda, VW, BMW, GM, Ford, Daimler, Fiat, iwm.

1.2 Fasalada ugu muhiimsan GEOMET®

Shaxda 1 - Isbarbardhigga Nidaamyada Dahaarka ee GEOMET® ee Caadiga ah

Fiiro gaar ah: Waxqabadka dhabta ahi wuxuu ku xiran yahay culeyska daahan (sida caadiga ah>24 g/m²), diyaarinta substrate, iyo PLUS® dookhyada koofiyadaha oo si dheeraad ah u hagaajiya isugeynta iskudhafka (μ ≈ 0.06-0.20 ee ISO 16047).

2. Bolts laba geesood ah - Naqshad iyo Heerarka

Dhallaanka madaxa ee lix geesoodka ah ayaa ka mid ah xireyaasha farsamada ee aadka loo isticmaalo. Madaxooda lixda geesoodka ah ayaa u oggolaanaya in si fudud loogu adkeeyo furayaasha ama saldhigyada caadiga ah waxayna bixiyaan dusha sare ee xajmiyeedka. Marka lagu daro daahan GEOMET®, boolalyadani waxay keenaan labadaba xoog farsamo oo sarreeya iyo iska caabin daxalka muddada-dheer.

2.1 Heerarka Caalamiga ah ee khuseeya

• TS EN ISO 4014 / DIN 931 - Boolal madax hexagon ah oo leh dun qayb ah (madaxa hoostiisa hoostiisa).
• TS EN ISO 4017 / DIN 933 - Biraha madaxa hexagon ayaa si buuxda u dunsan.
• TS EN ISO 898-1 Qalabka makaanikada ee xirmooyinka ka samaysan birta kaarboonka iyo birta aluminiumka (fasalada guryaha 4.6-12.9)
• TS EN ISO 10683 - Dahaarka zinc flake-ka aan-korontada ahayn ayaa lagu dabaqay xirmooyinka (si toos ah ayey u khuseysaa GEOMET®).
• ASTM F1136 / F1136M - Zinc/aluminium dahaarka ilaalinta dahaarka ee xirayaasha.

2.2 Fasalada Hantida Makaanikada (ISO 898-1)

Shaxda 2 - Fasalada Hantida Guud ee Birta Hex Bolts

Daahan GEOMET® ayaa si gaar ah qiimo ugu leh fasallada 10.9 iyo 12.9 sababtoo ah habka aan elektrolytka ahayn ayaa ka fogaanaya qallafsanaanta hydrogen ee ku dhici karta koronto-galvanizing caadiga ah.

2.3 Heerarka cabbirka caadiga ah

Boolalka mitirka ee laba geesoodka ah ayaa inta badan lagu bixiyaa dhexroorka M5 ilaa M36 (iyo ka weyn marka la codsado). Dhererka xargaha ayaa raacaya taxanaha ISO metric aan dhab ahayn. bolts-ka qayb-xidhka ah (ISO 4014) waxay ka tagaan shakac aan xadhig lahayn oo hagaajiya xoogga dhogorta; bolts-ka buuxa (ISO 4017) waxay kordhiyaan ka-qaybgalka godadka la taabtay.

3. Xogta Waxqabadka & Astaamaha Dahaarka

3.1 Xogta Iska caabinta Daxalka

4.2 Talooyinka Xulashada

Marka aad sheegayso GEOMET® boolal lix geesood ah, tixgeli kuwa soo socda:

1. Fasalka daxalka ee loo baahan yahay → dooro GEOMET 321 (standard), 500 (xakamaynta-xakamaynta) ama 720 (ilaalinta ugu badan).
2. Awoodda makaanikada → dooro heerka hantida 8.8, 10.9 ama 12.9 iyadoo loo eegayo culeyska iyo arrimaha badbaadada.
3. Nooca dunta → qayb ka mid ah dunta (ISO 4014) ee kala-goysyada muhiimka ah ee xiirid; dunta buuxda (ISO 4017) ee hawlgelinta ugu badan.
4. Isku xidhka jajabka → cadee PLUS® koodhka sare haddii xidhiidhka la xakameeyey uu muhiim yahay.
5. Shuruudaha deegaanka & xeerarka → GEOMET® waxay qancisaa RoHS, REACH iyo ELV iyada oo aan laga dhaafin dheeraad ah.

4.3 Qoraalada Hubinta Tayada

Codsadayaasha dahaarka sumcadda leh waxay hayaan shahaadooyinka nidaamka (ISO 9001) waxayna inta badan hayaan oggolaanshaha OEM (Toyota, GM, iwm.). Dhumucda dahaarka, adhesion (tijaabada cajalad), waxqabadka milixda-buufinta iyo isku-dhafka isku-dhafka ah waa in lagu caddeeyaa ISO 10683 iyo sawirada macaamiisha. Muuqaalka muuqaalku waa cawl macdan ah oo isku mid ah; Kala duwanaanshaha madow (GEOBLACK®) sidoo kale waa la heli karaa marka qurxinta ama aqoonsiga loo baahan yahay.

5. Gabagabo

GEOMET® (久美特) dahaarka leh boolal laba geesood ah waxay isku daraan isku halaynta farsamada ee la xaqiijiyay ee xirmooyinka hex-madaxa heerka ISO oo leh dahaar casri ah oo aan chromium-ka lahayn zinc-aluminium kaas oo bixiya ilaalinta daxalka ee gaarka ah, u hoggaansanaanta deegaanka iyo xorriyadda ka-hortagga hydrogen-ka. Haddi loo isticmaalo chassis baabuurta, birta qaab dhismeedka ama mishiinada warshadaha, xidhidhayaashani waxay bixiyaan farsamo ahaan heer sare ah iyo xalka mustaqbalka ee dalbashada codsiyada.

Talooyinka mashruuca-gaarka ah, tifaftirka dahaadhka ama xogta hantida makaanikada, la tasho heerarka ISO ee khuseeya (4014, 4017, 898-1, 10683) iyo xaashida xogta farsamada ee ay soo saartay NOF Metal Coatings Group ama codsadayaasha idman.
