Phosphating biraha guriga

Tan iyo dadka bartay in la sameeyo birta ku leh Dadka kacay arrinta af ilaalinta ee alaabta ka soo jeeda burburinta daxalka. Miridhku - cadowga ugu weyn ee dusha biraha kasta oo ilaa maantadan la joogo. Hababka fiicnaaday dilka iyo hab ka hortagga daxalka, dhab ahaan suurto gal ah si loo gaaro natiijada cajiib ah dagaalka ka dhanka ah habka kiimikaad ee dabiiciga ah. Weli dammaanad daxalka nonsusceptibility dhamaystiran wax aan macquul aheyn.

waxaa suurtagal ah in lagu daweeyo biraha laftiisa guriga?

Si aad u taariikhda, ka mid ah hababka la heli karo ilaalinta qalabka ferrous ka sarkhaansan arrimood burbur phosphate xusay kacaya. Birta ka dib markii reaction kiimikada dhiganta noqdo iska caabin ah ay xirtaan sare, taas oo si weyn u sii dheerayn ay la isticmaalo si toos ah.

difaaca ugu fiican ee miridhku bir ah iyo qudhmay oo waa ay daahan dusha khafiif ah, oo kali ah filimka la arki karo. Marka guriga, shuruudaha phosphate bir u muuqataa hawl Herculean la xiriira category ee aan macquul aheyn ka. Indeed, waa kaliya in goobaha warshadaha leeyihiin qalabka lagama maarmaanka ah iyo reagents loo baahan yahay. Dhab ahaantii, iyaga oo raacaya xeerarka adag iyo xaaladaha si loo gaaro natiijada la rabay awoodo qof kasta oo waxbarasho farsamo lahayn.

Reagents in loo baahan yahay phosphating

An phosphating faa'iido guriga oo dheeraad ah waa in ay milgadaa: film ilaaliya raagaya waxaa la aasaasay on dusha sare ee dhammaan Alloys marka laga reebo birta-daawaha sare. Intaas waxaa sii dheer, lakabka dusha sare la stseplivaetsya fiican preform saldhig bir ah. Sida qalabka loo isticmaalo phosphatizing biraha:

• manganese,
• zinc,
• phosphates bir ah.

Faa'iidada daaweynta phosphate birta

technology casriga ah ee codsanaya Halabuurka kiimikada phosphate ogolaanaya si ay u daboosho dusha biraha la dhumucda yar - yar 5 micrometers. Qaabkan bir ah ka baaraandegidda ka hortagtaa in ay burbur iyo bixiyaa difaac ka saamaynta dibadda, xaqiijinta isticmaalka daba dheeraaday ee alaabta birta ah ee xaaladaha oo dhan, oo ay ku jiraan:

• marka qoyaan xad-dhaaf ah;
• sarkhaansan qase kiimikada dagaal;
• markii xiriir la saliidaha engine,
• hoos danab korontada sare;
• saldhig ahaan dahaadhka ranjiga ah.

Phosphating biraha waayo, rinjiyeynta siin doonaa ilaalinta lagu kalsoonaan karo ka mid ah maaddooyinka, laakiin sheyga weli noqon doonaa nugul marka ka dhacay deegaan acidic ama cawaaqib xumadoodu. Oo weliba xayd ku qalab kasta oo daahan dusha birta dhex gelin qoto dheer gelin layers of filimka ilaaliya isagoo heer sare ah porosity. Amda The kor Alloys dusha - meel kale oo wanaagsan, ogolaanaysaa dhihi haa phosphating hor rinjiyaynta biraha.

Technology iyo farsamo phosphating warshadaha

Ka hor inta Socota codsiga of lakabka filim, waxaa muhiim ah in la fahmo oo sideeda oo dhexdhexaad ah, taas oo bir ah lagu meeleeyo. technology phosphating biraha raacay by xayd wax rinjiga ma ku haboon yahay jimicsi guriga. Iyadoo "Mazhef" Xalka daroogada taas oo qabanaysa capacitance badan, waayo, ganacsi, iyo birta dahaarka leh kula lakabka ah oo aad u khafiif ah, laakiin aad raagaya iyo wax ku ool ah. Si buuxda u soo maaxanaysay in phosphating ee qubeyska oo ka mid ah macdan ah article waa kuleelka in heerkulka yareysey iyo refluxed saacad. Intaas ka dib gudoohoda hesho, filimka siinayaa si buuxda u adkayn, la xoojiyo, habka dhamaadka dusha electroplate isticmaalaya qalabka hadal haynta ama sandblasting.

Isticmaalka habka kor ku xusan la odhan karaa waa xaq oo kaliya in ay dhacdo ka baaraandegidda dhismayaasha waaweyn. phosphating la mid ah adeegyada biraha buriyay in hoolalka warshadaha ee rogid, kharash macaamiisha ah ee qadar hufan.

Sidee in ay la tacaalaan biraha guriga: "qabow" electroplating

Waayo, wax soo saarka electroplating dhexdhexaad ka badan ku habboon in ay door biday in ay technology aasaasiga ah. Waxaan ka hadleynaa phosphating acid phosphoric biraha, diyaarinta taas waxaa laga heli karaa xataa guriga. Waayo, reaction guul waa inay raacaan fiirsashada saxda ah ee xubno ka kiimikada. Kuwa soo socda ayaa qayb ka ah xalka ee cabirku yahay xaddi walax (in garaam) 1 litre oo biyo ah:

• phosphoric acid - wax ka badan 40;
• zinc amooniyam - 200;
• zinc xabagta - 15;
• Sodium sulfate - 8.

Nidaamka ma qaadan doontaa waqti badan - si ay u diyaariyaan xal iyo reaction kiimikada degdeg ah qaadan doontaa qiyaas ahaan nus saac. Mid ka mid ah shuruudaha ugu muhiimsan oo waa in la raaco inta lagu guda jiro howsha bir ah, waa midda saxda ah xal iyo heerkulka (aan ka yarayn +18 ° C iyo in aan ka badnayn +25 ° C). Habka Tani waxay u ogolaaneysaa in la helo phosphating a bir qabow guriga, laakiin waa wax badan soo saarka liita bir tayada processing ka "Mazhef" diyaarinta - dhumucda ugu badan ee filimka sababtay inta badan kama weyna 5 microns.

qaybo bir phosphating Electrochemical

Inta badan teknoolajiyada ee ka baaraandegidda alaabta birta ah u qalantay caan goobta shaqada, ayaa si guul leh loo isticmaalo by amateurs. Kaasi waa electrochemical machining oo dusha birta daahan micnahoodu yahay filimka lagu kalsoon yahay ay sabab u tahay falcelinta ka mid ah elektrolytka iyo hadda. The salaysan mabda 'hawlgalka ee habkan waa isticmaalka "Mazhef" acid phosphoric ama daroogada.

Iron workpiece waa inuu kan la phosphated, Jaha koronto. Dhismaha ayaa la hoos geliyey xal qubeyska la diyaar ka hor iyo sida loo isticmaalo sida dhengedihii zinc anode ah - sidoo kale ay u baahan yihiin in ay keenaan korontada. Si aad si sax ah loo farsameeyo bir ma loo baahan yahay in door biday in ay isticmaalka network-danab sare, waa ku filan tahay 25 V AC ama DC hadda korontada.

"Mazhef" - Halabuurka ugu fiican ee Primer birta ka hor inta rinjiyaynta

phosphating nidaamka socdaa muddo gaaban - celcelis ahaan, ilaa nus saac ah. qalab Tani waa ku haboon ka baaraandegidda alaabta si toos ah dhexdhexaad ah. Waayo, waxyaabaha la design joomateri dheeraad ah oo adag waa inay doortaan si ka duwan bir ah daahan phosphate si looga fogaado qaybinta sineyn ee mideyso film. Sida loo isticmaalo warshadaha iyo guriga "Mazhef" waa Halabuurka ciidda tayo sare leh oo haysta shahaadooyin oo dhan iyo GOST u dhigma. phosphating biraha jirka baabuurta - mid ka mid ah sababaha ugu badan ee isticmaalka muqaadaraadka. Si aad gaariga ka miridhku ku ilaaliyaan, "Mazhef" codsatay xitaa meelo halkaas oo aadka loo yaqaan kuwa, rinjiga dheer ma socon doono (tusaale ahaan, hoose ee gaariga).

Si aad u sii wado howsha biraha, lagana rujiyey tiraa wasakh, ciidda, qayb ka mid ah dhoobo iyo waxa ay si fiican degreased. isku dar shaqaynta la diyaarin karaa si madax banaan, laakiin la taaban karo markii la badbaadiyo oo si siman u qaybin doonaa foomka buufis sii daayo. Sayidka reagents qaar ka codsatay in ay birta loola dhaqmo burush. Laakiin habkan of qaybinta ma habboona in maqnaanshaha khibrad priming - waa mid aad u muhiim ah in la raaco codsiga uniform of Halabuurka phosphate ah.

Talooyin ku saabsan isticmaalka xeryahooda phosphate

In daaweynta ee qaybo bir yar oo leh "Mazhefom" noqdo suurto gal ah, iyo geedi socodka dukumiintiyo kulul filimka ilaaliya. Halabuurka kale u qaadan waxaa laga yaabaa in ey ka heleen oo amooniyam zinc iyo phosphoric acid. In koorsada of diyaarinta tacsida ma daqiiqad illoobi kartaa oo ku saabsan digniin iyo ammaanka oo aasaasi ah:

• Waxaa lagu talinayaa inay xidhaan muraayadaha ilaaliya gaar ah.
• Si looga hortago khubad ka taagan laba laba gelisid u shaqeeya waddada ama qol hawo.
• Marka la dhameeyo nidaamka, gacmaha si kiimikada qayb ha saarin on xub-axaleedka ee indhaha, afka maydhaa.

Daaweyntu waxay final ka dib markii phosphating qaybo

Sida caadiga ah, phosphate biraha guriga ma aha heerka ugu dambeeya ee processing alaabta. Tan iyo porosity ee qaab-dhismeedka difaaca filimka galvanic dheeraad ah waxay saameyn kartaa guryaha shaqeynta iyo waxqabadka ay, dusha biraha waa passivated. Sida xal si loo hubiyo in ay macaanaa iyo evenness dahaadhka, iyadoo la isticmaalayo dichromate potassium ama dichromate sodium. In geeddi-socodka ah ee biraha dhammaystiraya waa mid aad u muhiim ah in aan la lumin dhaqanka heerkulka: maadooyinka la film phosphate la Hawiyaha ah xal 80-degree iyo iyaga samayisma ugu yaraan 20 daqiiqo. Ka dib markii passivation, sheyga waxaa lagu daaweeyaa saliid cabbeeyo, ka dibna, xal of shidaal iyo dareere silicone in cabirku yahay 1:10.

Sidee si uu u hubiyo tayada filimka ilaaliya on biraha?

daliil u tahay in daahan ee sababtay dhiganta sifooyinka sheegay, waxa la arkaa in ay qaab-dhismeedka ganaax-grained iyo tirada ugu yar ee daloolada. Production sidoo kale xisaabta lagu darsadaa cuf gaarka ah ee lakabka codsatay: miisaanka filimka waa in aan ka badnayn saddex grams halkii 1 square. meter. phosphating Celceliska (daaweynta biraha dhacdaa marka heerkulku karkaraya) oo u ogolaanaya in la helo daahan xoog leh kuwaas oo dhumucdiisuna waxay gaadho 7 microns iyo qabow nooca saameynta lakabka mideyso tagaa oo dhumucdiisuna yar oo aan sidaa leeyahay tayo miskiin ah.

A talooyin dhawr, waayo, phosphating: waxaad u baahan tahay inaad ogaato?

Si aad si guul leh phosphating dhirta wax soo saarka biraha waxaa muhiim ah inaad bixiso si qodobbada soo socda fiiro:

• Habka ugu fudud ee diyaarinta koollada phosphating ah, taas oo loo isticmaali karaa in lagu daweeyo qaybaha toosan, sida soo socota: in ay isku daraan "Mazhef" ama xal cooshado of acid phosphoric iyo amooniyam zinc la filler dhexdhexaad ah - budada Rusheyn kartaa, kaolin. Home - hayn saamiga (3 qeybo ka mid ah xal per 2 walax crumbly).
• xal phosphate The lagu dari karaa qaybaha maaddooyinka - this badbaadin doonaa xoog loogu diyaar phosphating biraha. Ujeedada this, 1 litir oo biyo ah loo baahan yahay in lagu daro 45 g oo amooniyam sodium iyo monophosphate sodium, iyo qaado nus ka mid ah saabuunta. Details waqtiga qubeyska phosphating waa in la kordhin laba jeer.
• Si aad u saaro miridhku ka dusha biraha u baahan tahay in aad ku darto acid phosphoric a polyphosphates adag. Kor u qaadista heerka of xal this si ay uga caawiyaan wakiilka gaarka ah qoynta - nadiifi doonaa dusha birta.
• Xawaaraha Phosphating - walax ku daray in ay ka kooban loogu daweeyo dusha sare. waxaa la, nidaamka oo dhan qaadataa ugu yaraan mar.

dhismaha bir daaweynta Phosphate of daawaha kasta

Ma garato in qabashada isku mar dhowr geeddi socodka phosphating biraha waa faa'iido weyn ma aha oo kaliya in industry, laakiin sidoo kale nolol maalmeedka, industry this noqon kartaa meel ka iman kara horumar of technology electroplating jira. Intaa waxaa dheer leh si naftu dhaqaale, taas oo iska cad marka phosphating guriga, daaweynta bir ah waxa uu leeyahay faaidooyin kale. Tusaale ahaan, xeryahooda phosphate ay awoodaan si ay u ilaaliyaan ka burburinta madow ma aha oo kaliya, laakiin sidoo kale Alloys non-ferrous (copper, cadmium, aluminium, iyo D. sidaas on.).

Si loo ilaaliyo biraha ka daxalka sababa arrimo dibadeed, cimilada, waxaa la farsameeyo ka dib ayaa isla markiiba. khatar ku jirin in ay biraha, ma uu la qaban karaa, laakiin dhab ahaan inta badan keensataa qiimaha madaxtooyada - in ay dhacdo gelinayn wax soo saarka bir ah lagu daweeyey qolka la qoyaan xad-dhaaf ah huurada buluug sameyn karaan dushiisa.
