Bolt gaari DIN603

Qaab dhismeedka asaasiga ah:

Walxaha saldhigga ah: sida caadiga ah birta kaarboon (sida 45 # birta, 40Cr) ama birta aan lahayn, oo leh lakab zinc ah oo daboolaya dusha sare ka dib galvanizing.

Nooca dunta: sida caadiga ah dunta loo yaqaan 'trapezoidal thread' (Tr type) ama kubbadda kubbadda, kan dambe waxaa inta badan loo adeegsadaa xaaladaha saxda ah ee saxda ah.

Geedi socodka galvanizing: loo qaybiyey zinc elektaroonik ah (daahan khafiif ah oo labis ah) iyo zinc-kulul (daahan qaro weyn, iska caabin daxalka xooggan).

2. Astaamaha geeddi-socodka galvanizing

Habka ka hortagga daxalka:

Ilaalinta anode-ka allabari: Lakabka zinc wuxuu doorbidayaa oxidizes, dib u dhigaya daxalka birta substrate-ka.

Caqabadda Jireed: Lakabka Zinc cufan ayaa ka soocaya uumiga biyaha, ogsijiinta, iyo substrate-ka ee xidhiidhka.

Isbarbardhigga habka:

Nooca habsocodka dhumucda dahaarka iska caabbinta daxalka xaaladaha lagu dabaqi karo Qiimaha

Galvanized 5-20 μm oo loogu talagalay qalabka guud ee gudaha, oo leh jawi hoose oo daxalka ah

Galvanizing kulul 50-150 μm, aad ugu fiican bannaanka, kiimikooyinka, iyo deegaanka badda

3. Faa'iidooyinka asaasiga ah

Iska caabinta daxalka: Waxay ku habboon tahay qoyaanka, buufinta milixda, aashitada iyo deegaanka alkaline (sida maraakiibta iyo qalabka kiimikada).

Dhaqaalaha: Kharashka galvanizing-ku wuu ka hooseeyaa kan birta birta ah ee caaga ah, cimriguna si weyn baa loo dheereeyey.

Dayactirka hooseeya: sifooyinka is-bogsiinta ee lakabka zinc waxay yareeyaan baahida dayactirka joogtada ah.

La qabsiga: Waxa lagu jaanqaadi karaa hababka gudbinta kala duwan, sida matoorada stepper iyo matoorada servo.

4. Xaaladaha codsiga

Mashiinnada bannaanka: mishiinnada dhismaha, qalabka beeraha (oo u bannaan biyaha roobka iyo deegaanka carrada).

Injineerada maraakiibta iyo badda: habka kor u qaadida sagxada, xakamaynta waalka (u adkaysta daxalka buufinta milixda).

Qalabka kiimikaad: habka gudbinta kittle falcelinta, qalabka nidaaminaya dhuumaha (ashitada iyo dhexdhexaad dhexdhexaad ah alkali).

Warshadaha dhismaha: albaabbada otomaatiga ah iyo daaqadaha, meelaha wax lagu qaado (shuruudaha ka hortagga miridhku qiimo jaban).
