Dulmar Farsamo oo Dhameystiran ee Daaweynta Dusha sare ee Dacromet iyo Tilmaamaha Koofiyadda Madaxa Socket

1. Hordhac

Dacromet-coated hex socket socket screws oo u hoggaansamaya heerka DIN 912 waxay ka dhigan tahay xal-xirfadeed heer-sare ah oo isku daraya farsamaynta heerka sare ee qalabka madaxa-socket-ka ee saxda ah oo leh iska caabbinta daxalka sare ee daaweynta dusha Dacromet. Xidhiidhiyayaashan ayaa si weyn loogu isticmaalaa baabuurta, dhismaha, badda, tamarta dabaysha, iyo codsiyada mishiinada warshadaha halkaas oo labadaba daacadnimada qaab-dhismeedka iyo ilaalinta daxalka muddada-dheer yihiin muhiim.

Maqaalkani wuxuu bixiyaa dulmar farsamo oo faahfaahsan oo laga soo qaatay laba aragtiyood: habka daahan Dacromet, kaas oo siinaya xirayaashan sifooyinkooda gaarka ah ee ka hortagga daxalka, iyo DIN 912 socket cap screw joometry, kaas oo qeexaya naqshadooda farsamada iyo heerarka cabbirka.

Jaantuska 1. Dacromet-Daaban DIN 912 Socket Cap Shoppings

2. Dacromet Technology Coating

Dacromet waa horumarsan, biyo ku salaysan, tignoolajiyada dahaarka ka hortagga daxalka u saaxiibka ah deegaanka Waa nidaam dahaar aan elektaroonik ahayn oo ka kooban jajabyo zinc aadka u fiican, jajabka aluminiumka, xeryahooda aashitada chromic, iyo xidhayaasha organic gaarka ah. Marka lagu daaweeyo heerkul sare, qaybahani waxay sameeyaan daahan macdan ah oo cufan, lakabyo badan leh oo si bir ah ugu xidha substrate-ka birta.

Si ka duwan koronto-samaynta caadiga ah, oo ku tiirsan meel dhigista korantada, Dacromet waxay shaqaaleysiisaa hab-miirid ama habka biyo-mareenka. Xidhiidhiyayaasha waxa lagu dhex shubaa daaha dareeraha ah ee Dacromet, ka dibna xoog ayaa loo saaray in laga saaro walxaha xad-dhaafka ah, oo ugu dambeyntii lagu dubay qiyaastii 300 darajo Celsius. Habka daawayntani waxa ay sababtaa jajabka zinc iyo aluminiumku in ay isku dhejiyaan oo isku daraan, abuuraan lakab-cawlan, lakab ilaalin ah oo aad u dheggan.

Habka daahan Dacromet wuxuu ka kooban yahay dhowr marxaladood oo taxadar leh:

Talaabada	Habka	Sharaxaada
1	Hoos u dhigid	Ka saarida saliidaha, saliidaha, iyo wasakhowga dusha sare iyadoo la adeegsanayo walxaha nadiifinta alkaline
2	Rasaasta Qaraxday	Nadiifinta makaanikada si looga saaro miisaanka, miridhku, iyo lakabyada oksaydhka ee korka xidhaha
3	Dahaarka Dip-Spin	Dhex-gelinta dahaarka dareeraha ee Dacromet oo ay ku xigto wareegga centrifugal si loo xakameeyo dhumucda daahan
4	Dawaynta Koowaad	Dubo at 80-120 darajo Celsius si ay u uumi-baxa qoyaanka iyo samaynta filimka bilowga ah
5	Dip-Spin Labaad	Lakabka dahaarka labaad ee ikhtiyaarka ah ee ilaalinta daxalka ee la xoojiyey
6	Daawaynta kama dambaysta ah	Dubo at 280-320 darajo Celsius si aad u kala saartid jajabyada zinc / aluminium oo samee lakabka ilaalinta ugu dambeeya
7	Qaboojinta & Kormeerka	Qaboojinta la xakameeyey oo ay ku xigto hubinta tayada ee dhumucda dahaarka, adhesion, iyo muuqaalka

3. DIN 912 Socket Head Cap Screws

DIN 912 waa Heerarka Warshadaha Jarmalka oo qeexaya cabbirka, dulqaadka, iyo sifooyinka farsamada ee biraha madaxa godka hex, oo sidoo kale loo yaqaanno Allen bolts ama biraha madaxa godka. Xidhiidhiyayaashani waxa ay ka kooban yihiin madax cylindrical ah oo leh wadista godad laba geesood ah, oo loogu talagalay in uu wado furaha Allen (furaha hex). Heerarka DIN 912 si weyn ayaa loo aqbalay si caalami ah wuxuuna u shaqeeyaa u dhigma ISO 4762.

Xirmooyinka koofiyada madaxa ee godka waxaa lagu gartaa saamigooda xoog-ilaa-cabbirkooda sare. Naqshadeynta madaxa cylindrical waxay u oggolaaneysaa xoogag isku dhejin ah oo sarreeya marka loo eego birta madaxa hex ee caadiga ah ee isla dhexroorka, halka hex drive-ka gudaha uu awood u siinayo in lagu rakibo meelo xaddidan oo xaddidan. Madaxu wuxuu ku fadhiyaa si nadiif ah ama ka hooseeya dusha sare marka lagu rakibo dalool aan caajis ahayn, oo bixiya muuqaal nadiif ah, muuqaal hoose.

3.3 Guryaha Makaanikada

DIN 912 caarada koofiyada madaxa waxaa laga soo saaray walxo kala duwan waxaana lagu heli karaa noocyo badan oo hanti ah. Fasalada hantida ugu badan ee birta madaxa godadku waa 8.8, 10.9, iyo 12.9, kuwaas oo muujinaya korodhka heerarka xoogga xajinta.

Heerka hantida	Qalab	Min. Xoogga Jilitaanka (MPa)	Min. Xoogga Wax-soo-saarka (MPa)	Hardness (HRC)
8.8	Birta Kaarboonka	800	640	22-32
10.9	Alloy Steel	1000	900	32-39
12.9	Alloy Steel	1200	1080	39-44
A2-70	Biraha Aan Lahayn 304	700	450	-
A4-80	Birta Aan Lahayn 316	800	600	-

4. Faa'iidooyinka Isku-dhafka ah: Dacromet + DIN 912

Marka dahaarka Dacromet lagu dabaqo DIN 912 socket screws koofiyada madaxa, natiijadu waa xire isku daraya waxqabadka farsamada ee gaarka ah iyo ilaalinta daxalka oo aad u wanaagsan. Isku-dhafkan ayaa ka dhigaya Dacromet-dahaarka daboolka daboolka daboolka ah ee dooqa la doorbido ee deegaan baahida loo qabo.

5. Gabagabo

Dacromet-dahaarka leh ee DIN 912 godka madaxa socket wuxuu u taagan yahay isgoysyada injineerinka sare ee sare iyo naqshadaynta saxda ah. Nidaamka daahan Dacromet wuxuu bixiyaa xannibaad adag, oo mas'uul ka ah deegaanka oo ka sarreeya koronto-sameynta caadiga ah iyadoo loo eegayo margin muhiim ah, halka DIN 912 joomatari ay hubiso xoog isku dhejinta oo sarreeya, ka qaybqaadashada wadista wanaagsan, iyo rakibida meel bannaan.

Si wada jir ah, tignoolajiyadaani waxay soo saaraan xire awood u leh in ay si la isku halleyn karo uga shaqeeyaan jawiyada warshadaha ugu baahida badan. Maaddaama ay warshaduhu sii wadaan inay dalbadaan nolol dheer oo adeeg ah, dayactirka oo yaraada, iyo hababka wax soo saarka ee deegaanka u hoggaansamaya, daboolka daboolka daboolan ee Dacromet wuxuu ahaan doonaa qayb muhiim ah injineernimada iyo dhismaha adduunka oo dhan.

Kooxaha wax soo iibsiga iyo injineernimada, qeexida Dacromet-dahaarka DIN 912 socket cap screws waxay hubisaa u hoggaansanaanta heerarka ilaalinta daxalka caalamiga ah iyadoo la ilaalinayo waxqabadka farsamada ee looga baahan yahay codsiyada badbaadada-muhiimka ah.

Ma Hayso. Xiga.
