Fasalka 8.8 Black Oxide Hex Socket Head screws- Dulmarka Farsamada ee Ilaalinta Daxalka iyo Nakhshadda Madaxa 

2. Fasalka 8.8 Madaw oksaydh Dhamaystiran: Ilaalinta Daxalka

2.1 Waa maxay Black Oxide?

Okssaydhka madow, oo sidoo kale loo yaqaan madow, waa daahan kiimikaad beddelaadda oo la soo saaro iyada oo ka falcelinaysa dusha biraha birta ah ee leh xalka oksaydhaynta alkaline ee heerkul sarreeya (sida caadiga ah 140 ilaa 150 darajo Celsius). Si ka duwan dahaarka elektiroonigga ah sida zinc ama Dacromet, kaas oo dhigaaya lakab macdan ah oo gooni ah dusha sare ee substrate-ka, oksaydhka madow wuxuu u beddelaa lakabka ugu sarreeya birta lafteeda magnetite (Fe3O4), oksaydh madow oo deggan. Natiijadu waa dhuuban, oogada matte-madow oo noqda qayb muhiim ah oo ka mid ah xiraha halkii lakabka lagu daro.

2.2 Habka Black Oxide

Habka caadiga ah ee oksaydhka madow ee xirayaasha Fasalka 8.8 waxay ku lug leeyihiin marxaladaha soo socda:

Nadiifinta iyo nadiifinta alkaline-ka si looga saaro saliidda, jarista dareeraha, iyo wasakhowga dukaanka.

Asiidh-qaadista si ay meesha uga saarto miisaan kasta oo dusha sare ah ama miridhku fudud.

Gelida qubeyska kulul ee alkaline-oxidizing (qiyaastii 141 darajo Celsius), halkaasoo lakabka magnetite uu ku sameeyo 10 ilaa 20 daqiiqo.

Ku luqluqashada iyo ku xidhida saliid ama dhux ka hortag ah miridhku, kaas oo kabsada lakabka oksaydhka oo leh xannibaad hydrophobic ah.

2.3 Astaamaha iska caabinta Daxalka

Isaga laftiisa, lakabka oksaydhka madow waa dhuuban (qiyaastii 0.5 ilaa 1.5 micrometers) iyo dalool, taas oo macnaheedu yahay inay bixiso iska caabin daxaleed oo yar marka loo eego dajinta zinc ama galvanizing-kulul. Si kastaba ha ahaatee, marka lagu daro saliid dheeri ah oo ka hortag ah miridhku ama dhuka, daahanku wuxuu gaaraa iska caabin milix dhexdhexaad ah oo qiyaastii 24 ilaa 96 saacadood ah, taas oo ku xidhan tayada daboolka. Ilaalinta heerkan ayaa ah mid ku filan gudaha gudaha, cimilada-koontaroolada, ama bay'adaha daxalka khafiifka ah halkaas oo xiruhu aanu soo gaadhin qoyaan toos ah ama buufin milix ah muddo dheer.

2.4 Faa'iidooyinka iyo Xaddidaadaha

1.Bedelka cabbirka eber: Sababtoo ah lakabka oksaydhku wuxuu ka hooseeyaa 2 micrometers, oksaydhka madow ma beddelo dulqaadka dunta. Xidhiidhiyayaasha fasalka 8.8 waxay ilaalinayaan heerka asalka ah ee 6g, taasoo ka dhigaysa dahaarka mid ku habboon shirarka saxda ah halkaasoo ay tahay in laga fogaado faragelinta dunta.

2.Kharashka waxtarka leh: Okssaydhka madow waa mid ka mid ah daawaynta dusha sare ee dhaqaalaha ugu badan ee la heli karo, si aad ah uga jaban darista zinc-nickel, Dacromet, ama beddelka birta-la'aanta ah.

3. Ma jiro qallal hydrogen ah: Si ka duwan sida korantada, geeddi-socodka oksaydh-madow ma dhaliyo gaasta hydrogen, isaga oo meesha ka saaraya khatarta isku-darka hydrogen-ka. Tani waxay muhiim u tahay xirayaasha Fasalka 8.8 ee ku shaqeeya heerarka walaaca sare.

4. Quruxda quruxda: Dhammaystirka matte-madow ee lebbiska ah wuxuu bixiyaa muuqaal nadiif ah, muuqaal xirfad leh kaas oo ku daraya shirarka midab-madow oo yareynaya iftiinka iftiinka.

5.Limitation - Iska caabbinta daxalka bannaanka ee xaddidan: Madow oksaydhku kuma habboona bannaanka, badda, ama bay'adaha daxalka sareeyo. Codsiyada noocaan oo kale ah, Dacromet, dhejinta zinc-nickel, ama birta aan daahin waa in la tixgeliyaa.

3. Madaxa cylindrical leh Hex Socket Drive

3.1 Guudmarka Naqshadda

Madaxa cylindrical (oo loo yaqaanno madaxa socket cap screw head ama DIN 912 / ISO 4762 madaxa) wuxuu leeyahay qaab qaabaysan oo fidsan oo dhexda ku yaal god saddex geesood ah. Dhexroorka madaxa ayaa caadi ahaan qiyaastii 1.5 jeer dhexroorka dunta magacaaban, dhererka madaxuna waa qiyaastii 0.6 ilaa 1.0 jeer dhexroorka shank, iyadoo ku xidhan cabbirka. Joometry Tani waxay bixisaa dusha sare ee madaxa hoostiisa iyadoo la ilaalinayo astaanta guud ee is haysta iyo mid hoose.

3.2 Faa'iidooyinka Naqshadeynta Madaxa Cylindrical

Xoogga sare ee isku dhufashada: Madaxa cylindrical wuxuu bixiyaa meel ka weyn oo korka leh marka loo eego naqshadaha countersunk ama badhanka, isaga oo u qaybinaya culayska ku dheggan aag ballaaran oo yareynaya khatarta soo galitaanka dusha sare ama waxyeellada qalabka shaqada.

Raad is haysta: Sababtoo ah madaxu wuxuu ku fadhiyaa dusha sare ee dusha halkii uu ka ahaan lahaa mid liidata, madaxa cylindrical wuxuu u baahan yahay kaliya dalool fudud ama dalool la taaban karo. Looma baahna hawlgal lid ku ah, fududaynta wax soo saarka.

Rakibaadda ama kor u-qaadista: Madaxa waxaa lagu rakibi karaa iyadoo la raacayo oogada (haddii codsigu oggolaado madax sare) ama dib loo geliyaa counterbore si ay si buuxda u nadiifiso, iyadoo bixisa dabacsanaan naqshadeed.

Muuqaal nadiif ah: Madaxa cylindrical-ka siman wuxuu soo bandhigayaa muuqaal hagaagsan, lebbisan kaas oo si qurux badan loo door biday mishiinnada, qalabaynta, iyo elektiroonigga macaamiisha.

3.3 Hex Socket Drive Faa'iidooyinka

Socket-ka laba geesoodka ah (Allen) wadista waa isku xirka qeexaya furka madaxa godka. Furaha Allen hex (wrench) wuxuu hawlgeliyaa nasashada lixda dhibcood ah, isaga oo gudbinaya qulqulka si uu u wado furaha. Nidaamka wadistani wuxuu bixiyaa faa'iidooyin dhowr ah oo kala duwan marka loo eego hex dibadda ah, Phillips, ama darawallada booska leh:

Gudbinta qulqulka sare: Socket-ka hex-ga gudaha waxa uu u adkeysan karaa xawliga aad uga sareeya kan Phillips ama dariiqyada xadhkaha goostay, taas oo awood u siinaysa in la adkeeyo qiyamka horudhaca sare ee looga baahan yahay xidhayaasha Fasalka 8.8 (ilaa 80% culayska caddaynta ee kala goysyada muhiimka ah).

Iska-caabbinta Camer-ka: Si ka duwan darawallada Phillips ee loogu talagalay inay kaamiro (ka-saarid) qulqulka sare hoostiisa, godka hex-ku wuxuu ilaaliyaa ka-qaybgal buuxa, isagoo yareynaya khatarta silbashada qalabka iyo dhaawaca madaxa.

Helitaanka astaanta hoose: Hex furaha hababku wuxuu ka imanayaa xagga sare (jihada axial), taasoo u oggolaanaysa in lagu rakibo meelo xaddidan oo furuhu aanu ka gaadhi karin dhinaca. Tani waxay si gaar ah qiimo ugu leedahay shirarka mishiinada cufan.

Khatarta dildilaaca oo yaraatay: Meesha xidhiidhka weyn ee u dhexeeya furaha hex-ga iyo darbiyada godadku waxay u qaybiyaan diiqada si siman, taas oo yaraynaysa fursadda qallooca gidaarka godka ama dildilaaca, xitaa ka dib markii soo noqnoqda rakibidda iyo wareegyada saarista.

4. Codsiyada caadiga ah

Fasalka 8.8 madaw oxide hex socket screws madaxa waxaa loo isticmaalaa warshado kala duwan oo kala duwan halkaas oo xoog dhexdhexaad ah, ilaalinta daxalka gudaha, iyo gelitaanka isku xidhan ee loo baahan yahay:

Mashiinada iyo qalabka wax soo saarka: Matoorada fuula, guryaha gearbox, shirarka bamka, iyo isku xidhka qaab-dhismeedka.

Gawaadhida (gudaha iyo qaybaha aan bannaanayn): Shirarka dashboard-ka, meeraha fadhiga, xidhmooyinka jar-jarrada gudaha, iyo qaybaha daboolka hoostooda ee ka magangalay soo-gaadhista cimilada tooska ah.

Qalabaynta iyo qalabka lagu rakibo: Saldhigyada caaryada, jigjiga iyo isku imaatinnada qalabka, iyo xidhidhaynta saxda ah ee soo noqnoqda ee caadiga ah.

Elektaroonigga iyo xayndaabyada: Qalabka rack-ku-saaran, sanduuqyada is-goysyada korantada, iyo muraayadaha kontoroolka halkaasoo nadiif madow oo nadiif ah iyo madaxa hoose ee la doorbidayo.

Alaabooyinka iyo qalabka dhismaha: Kala-goysyada alaabta guriga ee modular, meelaha bandhiga, iyo qalabka dhismaha ee gudaha.

5. Gabagabo

Fasalka 8.8 madaw oxide hex socket head screws waxay ka dhigan yihiin xal isku dheeli tiran oo isku mar ah oo wax ka qabta laba baahiyood oo injineernimo oo muhiim ah isku mar. Dhammaystirka oksaydhka madow waxa uu bixiyaa dhuuban, cabbir ahaan deggan, xannibaad daxal-la'aan ah oo hydrogen-embrittlement ah kaas oo ah mid dhaqaale iyo muuqaal labadaba ah. Iyadoo iska caabbinta daxalka ay xadidan tahay marka la barbar dhigo dahaarka qaaliga ah sida Dacromet ama zinc-nickel, waxay aad ugu filan tahay gudaha gudaha iyo meelaha khafiifka ah ee daxalka leh. Madaxa cylindrical oo leh hex socket drive, dhanka kale, wuxuu keenaa gudbinta qulqulka sare, awooda rakibida, iyo bilicsanaanta nadiifka ah taas oo ka dhigaysa doorashada la doorbiday ee shirarka makaanikada halkaas oo booska, isku halaynta, iyo muuqaalka dhammaan arrimaha. Si wada jir ah, labadan astaamood ayaa ka dhigaya darajada 8.8 godka madow ee oksaydhka madaxa koofiyadda inuu isku xidho xidheyaal la taaban karo, kharash-ku-ool ah, oo la isku halayn karo oo loogu talagalay noocyo badan oo codsiyada warshadaha ah.
