Xalka iska caabinta ee iska caabinta | Beeraha - tikniyoolajiyadda boodhka

Codsiga boodhka zinc ee ku yaal galvania

Nidaamka deciro waa tikniyoolajiyad daaq ah oo u adkeysta tikniyoolajiyadda dahaarka ah ee loo qaatay meel degane ah sannadihii ugu dambeeyay. Dhumucda daaqadu guud ahaan inta u dhaxaysa 5 illaa 10 μm. Qaabka ka-hortagga ka-hortagga wuxuu ku lug leeyahay ilaalin xasaasiyadda korantada ee la xakameynayo ee ay bixiso zinc substrate, saameynta xaafadda ee chranote, xaashiyaha aluminium, iyo sidoo kale "anodic" saamaynta "anodic" alumininium waxay joojineysaa zinc.

Marka la barbar dhigo jaakadaha dhaqanka-elektro-Galcation-ka, zinc-chrmate-ka ayaa muujinaya iska caabbinta xasaasiga ah ee aadka u adag, isagoo 7 ilaa 10 jeer ka sii adkaysanaya ka badan jaakadaha elektaroonigga ah. Kuma dhibtoodo abuurista hydrogen-ka ah, taasoo ka dhigeysa mid si gaar ah ugu habboon qaybaha xoogga badan. Intaa waxaa sii dheer, waxay ka muuqataa iska caabin kuleyl aad u sarreeya (dulqaadashada heerkulka illaa 300 ° C).

Geedi socodka oo u qulqulaya tikniyoolajiyadda dahaarka zinc-chrmate:

Qalabka loo yaqaan 'soltven' oo loo yaqaan 'Deventing'

Intaas waxaa sii dheer, tikniyoolajiyaddani waa mid aan fiicnayn inta lagu gudajiro howlaha daboolka, oo lagu calaamadeeyay kacaan kacaan taariikhda daaweyn dusha sare ah. Waxay ka dhigan tahay tikniyoolajiyadda goynta-goynta ee ku saabsan dawada dusha sare ee dawada ee adduunka maanta, gaar ahaan gawaarida gawaarida iyo mootooyinka, iyo qaybaha xoogga badan ee qaabdhismeedka laastikada iyo tubular. Daboolida ayaa soo bandhigaya xaalad ka dhalata sare, adheesion sare, aad u fiican dhasho, iska caabbinta cimilada sare, xasilloonida kiimikada sare, iyo astaamaha wasakhaynta wasakhaysan.

Muuqaalka xalka dahaarka ee DACRO waa midab isku mid ah oo cawlan. Xalka daboolka, ka dib markii lagu dubay geedi socodka kor ku xusan oo lagu dubay qiyaastii 300 ° C, oo dhalisay amyorous chrosites-ka oo daboolaya dusha sare ee go'yaasha iyo xaashiyaha xaashiyaha zinc iyo aluminium-ka ah ee ku xidhan substrate. Meelaha u dhexeeya go'yaasha zinc iyo aluminium waxaa sidoo kale ka buuxsamay chrosite chrosite, taasoo dhalisay in qashin khafiif ah oo khafiif ah oo daad-u-adkeysi u leh daalay.

Faa'iidooyinka galmada farsamada

Hawshu way fududahay in la shaqeeyo, waxoogaa tamar yar leh, waxay bixisaa iftiin dusha sare ah, oo ay ku badan tahay wax ku ool ah howsha warshadaha marka loo eego daaweynta-doro.

Xirmooyinka xargaha ee Galvanist-ka ayaa lagu dabaqay xajiyeyaasha dibedda ee caabbinta muddada-dheer ee iska caabbinta muddada-dheer lagu tiirsanaa sifooyinka unugyada ee allabari ee zinc. Sidaa darteed, daaha waa inay ku jirtaa zinc ku filan si loo hubiyo in qalabka dibedda ee dibedda ay leeyihiin tobanaan sano oo ah ilaalin-goynta.

Dhaqdhaqaaqa muddada-dheer, iyadoo aan loo eegin nooca tikniyoolajiyadda u adkaysiga casriga ah, nuxurka ka-hortagga ama yareynta xargaha xargaha loo baahan yahay qaab dhismeedka suuxdinta ama yareynta heerka habka loo yaqaan 'codka' korantada '. Sifooyinka zinc budada ah waxay ka dhigeysaa waxyaabo u adkaysata u adkeysta, taasoo horseedaysa codsigiisa baahsan.

Shiinaha ayaa leh ilo culus oo ku saabsan sunta zation-zinc-ka. Sanadihii la soo dhaafay, horumarinta iyo adeegsiga teknolojiyada boodhka ee zinc-ka, iyo sidoo kale sameynta jaakadaha isku-darka-culus ee loo yaqaan 'anti-antection' oo isticmaalaya walxaha dabiiciga ah, flulorocarbon, waxyaabo badan oo dhulka ah, iyo garaafyada, ayaa gacan ka geystey Hoos u dhigista isticmaalka ilaha aan dib loo cusbooneysiin karin iyadoo la siinayo teknoolojiyadda iyo agabyada caabbinta cusub ee loo yaqaan 'Technologs' iyo agab loogu talagalay codsiyada ilaalinta.
