Zitsulo phosphating kunyumba

Kuyambira anthu ataphunzira kuti zitsulo anthu panabuka nkhani lakuthwa za chitetezo cha mankhwala otengedwa pa chiwonongeko cha dzimbiri. Dzimbiri - mdani chachikulu padziko aliyense zitsulo lero. njira osatha bwino ndi njira kuteteza dzimbiri, ndithudi n'zotheka iyende zosaneneka polimbana ndi kusintha kwa zinthu zachilengedwe mankhwala. Koma zimatsimikizira mabuku nonsusceptibility dzimbiri zosatheka.

Kodi n'zotheka kuchitira zitsulo lokha kunyumba?

Pakali pano, pakati pa njira zimene zilipo kuteteza zipangizo akakhala ku zochita za zinthu zowononga Dziwani mankwala. Zitsulo pambuyo ofanana mankhwala anachita akukhala mkulu avale kukana, amene kwambiri kupitiriza ntchito yake mwachindunji.

Chitetezo chabwino koposa cha chitsulo dzimbiri ndi zowola ndi padziko wochepa thupi ❖ kuyanika, sadzachitanso kuonekera filimu. Kunyumba, zikhalidwe zitsulo mankwala zikuwoneka ntchito Herculean zokhudza gulu la zosatheka. Inde, si mu maofesi mafakitale ndi zida zina zofunika ndi reagents chofunika. Ndipotu, potsatira malamulo nthawi ndi zinthu kukwaniritsa chimene mukufuna mungathe munthu aliyense ndi wopanda maphunziro luso.

Reagents kuti ndi zofunika phosphating

An zina mwayi kunyumba phosphating ndi amagwiritsidwa ntchito mwanjira zosiyanasiyana: cholimba zoteteza filimu aumbike padziko pafupifupi kasakaniza wazitsulo onse kupatulapo apamwamba aloyi zitsulo. Komanso, pamwamba wosanjikiza ndi chabwino stseplivaetsya chitsulo m'munsi preform. Monga zipangizo ntchito phosphatizing zitsulo:

• manganese;
• nthaka;
• chitsulo phosphates.

Ubwino chitsulo mankhwala mankwala

zamakono kugwiritsa ntchito mankwala mipweya amalola kuphimba pamalo zitsulo ndi makulidwe osachepera - osachepera 5 micrometers. Njira imeneyi processing chitsulo chindiletsa kwe ndi umateteza amadza kunja, kuonetsetsa ntchito yaitali mankhwala zitsulo zinthu zonse, kuphatikizapo:

• pamene chinyezi kwambiri;
• mchikakamizo cha solvents aukali mankhwala;
• pamene anakumana ndi mafuta injini;

Njira imeneyi zimathandiza kupeza ozizira zitsulo phosphating kunyumba, koma zambiri otsika processing khalidwe chitsulo mankhwala ku "Mazhef" kukonzekera - kakakulu pazipita wa chotsatira filimu ndi zambiri saposa 5 microns.

mbali Electrochemical phosphating chitsulo

Ambiri mwa njira zamakono kwa processing mankhwala zitsulo waweruzidwa kutchuka kuntchito, akhala bwino ntchito mwa Amateurs. Amenewa ndi electrochemical Machining ndi pamwamba chitsulo ❖ kuyanika akwanitse odalirika filimu chifukwa zochita za electrolyte ndipo panopa. Maziko a ntchito mfundo za njira izi ndi kugwiritsa ntchito "Mazhef" asidi phosphoric kapena mankhwala osokoneza bongo.

Iron workpiece zimene ziyenera phosphated, wokwera elekitirodi. Yomanga ndi adatchithisira mu njira kusamba ndi okonzeka pasadakhale ndiponso ntchito ngati ndodo anode nthaka - nawonso akuyenera kubweretsa magetsi. Molondola pokonza zitsulo Sikuti amachita ntchito zopezera mkulu-voteji, ndi zokwanira 25 V AC kapena DC magetsi inawadutsa.

"Mazhef" - zikuchokera yabwino zitsulo phunziroli pamaso penti

phosphating ndondomeko kumatenga nthawi yochepa - pafupifupi kwa theka la ola. zida ndi abwino kwa processing molunjika sing'anga-kakulidwe mankhwala. Zinthu ndi zovuta zambiri kapangidwe zojambula asankhe njira zosiyanasiyana za chitsulo mankwala ❖ kuyanika pofuna kupewa likamaomba galvanizing filimu. Monga ntchito mafakitale ndi nyumba "Mazhef" ndi mkulu khalidwe nthaka zikuchokera kukhala ndi zikalata zonse ndi GOST lolingana. phosphating zitsulo magalimoto thupi - chimodzi mwa zifukwa ambiri ntchito zinthu. Kuteteza galimoto ku dzimbiri, "Mazhef" ntchito ngakhale mu malo amenewo kumene odziŵika amadziwika utoto nthaŵi yaitali (mwachitsanzo, pansi pa galimoto).

Zitatero ndi processing wa zitsulo, padziko kumatha dothi, fumbi, particles phula ndipo bwinobwino degreased. Ntchito osakaniza angathe kukonzekera paokha, koma ndithu kupulumutsa nthawi ndipo wogawana kugawa aerosol kumasulidwa mawonekedwe. Motero ena reagents ntchito kwa chitsulo mankhwala burashi. Koma njira imeneyi yogawa si yoyenera, pakalibe zambiri priming - n'chofunika kwambiri kutsatira ntchito yunifolomu ya mankwala zikuchokera.

Ayamikira kugwiritsa ntchito mankhwala mankwala

Mankhwalawa mbali yaing'ono zitsulo ndi "Mazhefom" imatheka, ndi otentha lamination ndondomeko ya filimu zozitetezera. An zikuchokera pangafunike kuganiza osakaniza kuthi nthaka nitrate ndi asidi phosphoric. Mu njira yokonza misa sangathe kwa mphindi angaiwale za kusamala ndi chitetezo zofunika:

• Iwo m'pofunika kuvala magalasi apadera zozitetezera.
• Pofuna kupewa chiphe kuima awiriawiri amathera ntchito pa msewu kapena chipinda mpweya wokwanira.
• Akamaliza wochita, sambani m'manja ndi mankhwala particles musaike pa nembanemba mucous maso, pakamwa.

Mankhwalawa omaliza phosphating mbali

Childs, zitsulo mankwala kunyumba si chomaliza processing mankhwala. Popeza porosity wa kapangidwe galvanic zoteteza filimu zingakhudze zina magwiridwe ndi ntchito zake katundu, pamwamba zitsulo ndi passivated. Monga njira kuonetsetsa kusalala ndi evenness wa ❖ kuyanika, ntchito dichromate potaziyamu kapena ndi sodium dichromate. Mu ndondomeko ya zitsulo liza n'chofunika kwambiri kuti asataye khalidwe kutentha: nzika ndi mankwala filimu kumizidwa mu njira 80 digiri ndi yoyambitsidwa kwa mphindi zosachepera 20. Pambuyo passivation, mankhwala mankhwala ndi lubricating mafuta, kenako, njira ya mafuta ndi madzimadzi silikoni mu chiŵerengero cha 1:10.

Kodi kuonanso ubwino wa filimu zoteteza pa zitsulo?

Kumasonyeza kuti ❖ kuyanika chotsatira limafanana ndi makhalidwe anati, amaona kuti kukhala dongosolo labwino-grained ndi mlingo wa pores. Yopanga komanso n'komwe kufunika enieni wosanjikiza ntchito: kulemera kwa filimu sayenera upambana magalamu atatu pa 1 lalikulu. mita. Avereji phosphating (chithandizo cha chitsulo limapezekanso pa kutentha otentha) amalola kupeza ❖ kuyanika amphamvu amene makulidwe akhoza kufika 7 microns ndi ozizira zimakhudza mtundu galvanizing wosanjikiza amapita ang'onoang'ono makulidwe choncho ali osauka khalidwe.

A ochepa nsonga kwa phosphating: muyenera kudziwa?

Bwinobwino phosphating zitsulo zomera kupanga Nkofunika kulabadira mfundo zotsatirazi:

• Chophweka njira yokonza ndi phosphating phala, amene angagwiritsidwe ntchito pofuna kuchiza zigawo umodzi, motere: kusakaniza "Mazhef" kapena njira zinawonongeka asidi phosphoric ndi nthaka nitrate ndi filler ndale - talc ufa, kaolin wa. Home - kusunga chiwerengero (3 mbali ya yankho pa 2 wofumbutuka chinthu).
• The mankwala njira akhoza kuwonjezeredwa zigawo degreasing - ichi adzapulumutsa mphamvu pokonzekera zitsulo phosphating. Chifukwa chaichi, 1 lita imodzi ya madzi m'pofunika kuwonjezera 45 ga nitrate soda ndi sodium wochuluka monophosphate, ndi theka supuni ya detergent. Tsatanetsatane zalowapo ndi phosphating kusamba ayenera ziwonjezeke kawiri.
• Kuchotsa dzimbiri ku zitsulo pamalo ayenera kuwonjezera asidi phosphoric polyphosphates zovuta. Kuonjezera dzuwa la njira kuthandiza wapadera wetting wothandizila - izo adzawononga pamwamba chitsulo.
• Accelerator Phosphating - chinthu anawonjezera kuti zikuchokera kwa mankhwala pamwamba. Atatero, dongosolo lonse amatenga osachepera nthawi.

Mankwala zomangamanga mankhwala yachitsulo aloyi iliyonse

Poganizira kuti likhale munthawi yomweyo njira zingapo zitsulo phosphating ndi mwayi kwambiri osati mafakitale komanso moyo wa tsiku ndi tsiku, ntchito imeneyi akhoza kukhala malo zingasinthe a alipo luso electroplating. Kuwonjezera kupulumutsiramo chuma, ndipo zimenezi zimaonekera pamene kunyumba phosphating, izi mankhwala chitsulo ubwino zina zingapo. Mwachitsanzo, mankhwala mankwala amatha kuteteza ku chiwonongeko osati wakuda komanso kasakaniza wazitsulo sanali akakhala (mkuwa, cadmium, zotayidwa, ndi zina zotero. D.).

Kuteteza zitsulo ku dzimbiri chifukwa cha zinthu zina, nyengo, ndi kukonzedwa mwamsanga pambuyo kupeza. Panalibe vuto kuti zitsulo, sakhoza ukachitikire, komabe nthawi zambiri amapeza phindu kukongoletsa - zinachitikira kuwayika mankhwala ankachitira chitsulo chipinda kwambiri chinyezi bluish zolengeza akhoza kupanga padziko.
