Daaweynta dusha sare ee qalabka waxaa loo farsameeyaa si loo hagaajiyo xaaladda dusha sare ee alaabta.Guud ahaan, waxaa jira daawaynta madow (oxidation dusha sare), daawaynta sifaynta adag, galvanizing, daaweynta fosfooraska, dahaadhida qalin kiimikaad, iyo daawaynta dusha sare ee iftiinka.Sifooyinkooda gaarka ah ee lagu garto astaamahooda Tilmaanta waa sida soo socota

1. Daawaynta mugdiga ah (oxidation dusha sare):

Daawaynta madow ee alkaline: Marka la dhigo birta xalka daawaynta alkaline ilaa 14ctc, birta lafteedu waxay ciyaartaa saamayn kiimiko waxayna samaysaa filim maqaarka madow oo korkiisa ah.Dhumucda kiliyaha madow ayaa ka hooseeya, maaddooyinka kiimikaduna waa afar-oxidation-bireed.Kortex wuxuu leeyahay saameyn lid ku ah miridhku.

2. Daaweynta saliidda adag:

Kaliya ku buufi saliidda adag ee dusha sare ee iliga taayirrada ee qalabka, iyo saliidda ku dheggan dusha si ay u engegaan si ay u sameeyaan filim maqaarka ah.Qaybaha sulfide Distan ee ku jira maaddooyinka dufanku waxay galaan unugyada birta si ay u ciyaaraan saameyn sifeyn.Gaar ahaan socodsiinta bilowga ah ee gears ama ka hortagga saamaynta sifaynta ee dhaqdhaqaaqa-yar ee ay sababto dhaqdhaqaaqyo yaryarGuud ahaan waxaa loo isticmaalaa meel aan saliid saliidayn lagu isticmaali karin

3. Galvanized:

Daaweynta dusha sare ee ujeedada hagaajinta waxqabadka ka hortagga miridhku ee birta.Iyada oo la horumarinayo daaweynta rhinate passivation, waxqabadka muuqaalka ayaa sidoo kale si weyn u fiicnaaday.Dhumucda lakabka dhejiska ayaa ka duwan, guud ahaan qiyaastii 225 μm.

4. Daaweynta Fosfooraska:

Daawaynta fosfooraska: Birtu waxa ay ku dhex milmidaa kuleyliyaha fosfatada si loogu daweeyo kiimikaad, si ay birta dusheeda u samaysato xuubka ilaalinta fosfatetada.Iska caabbinta ka-hortagga miridhku ee kiliyaha fosfooraska ayaa leh iska caabin wanaagsan oo xoqan iyo saameyn saliideed, sidaas darteed inta badan waxaa loo isticmaalaa daaweynta qaybaha silbashada.

5. Dahaarka lacagta kiimikaad:

Iska caabbinta daxalka ee caabbinta kiimikaad / abrasion waa sarreeyaa, iyo habka qalinka-plated ma dhaafo koronto iyo electrolytic.Ku habboon alaabooyinka leh cabbirka sare iyo shuruudaha saxda ah iyo qaababka adag.

6. Daaweynta dusha sare ee Raydent:

Daawaynta Raydent waxay isticmaashaa hab la mid ah koronto-samaynta si ay u dhaliso 1 ~ 2 μm dhumucdiisuna waxay madow tahay filim nadiif ah oo oksaydh ah oo dusha ka ah alaabta hooyada.Sababtoo ah filimka maqaarka iyo buugga birta T, aad bay u adagtahay in la iska fujiyo.Awoodda iska caabbinta miridhku waa mid xoog badan/xirid -awood u adkaysata waa la wanaajiyey, midabkuna waa madow.

Fiiro gaar ah:

1. Iyadoo ay saamaysay qaabka iyo cabbirka, kortexku si isku mid ah uma samayn karo gudaha xididka ilkaha.

2. Dhacdooyinka u dhigma ee ROHS waxay u baahan yihiin in si cad loo qeexo si loo qeexo in daawaynta chromium lix geesood ah loo baahan yahay in meesha laga saaro.
