Kuenzaniswa nemaitiro akadai seplating uyepamusoro kurapwa, kuchenesa kunoratidzika kuva nhano isingakoshi.Vazhinji venyu vangasafunga kuchenesa mari yakakosha, nekuti kuchenesa kunongoda nguva nemari.Asi kutaura zvazviri, kuchenesa kwakakosha kumhando yechigadzirwa uye kune simba guru pane rinotevera maitiro.Zvakakosha kuongorora zvikonzero nei kuchenesa kwakakosha.
Pamberi pekupisa kwekupisa, nzvimbo yebasa rekushanda inowanzoita seyakachena uye haina kukanganisa pakuona kwekuona.Nekudaro, mumatanho mushure mekurapwa kwekupisa (senge nitriding), matambudziko anokonzerwa nekusachena kwepasi kunoratidzwa.Kugadziriswazve kwezvakaremara zvigadzirwa kunodhura maererano nenguva nemari, uye zvigadzirwa zvakakanganisika hazvigone kugadzirwazve kazhinji.
Kana imwe yematambudziko akadaro, tinofanira kuongorora zvikonzero nekukurumidza sezvinobvira.Mechanical uye michina zvinokonzeresa zvinofanirwa kutariswa kutanga: rudzi rwezvinhu, chimiro chezvikamu, nitriding choto maitiro, uye mechanic processing.Kana zvinhu izvi zvichigona kubviswa, kukanganisa kunowanzo kukonzerwa neasingaoneki diffusion-blocking layer pamusoro pebasa rekushanda, izvo zvinoreva kuti imwe yakasara pane imwe nzvimbo yakachena inotaridzika inokonzera kukanganisa.
Pamberi pekupisa kupisa, chikamu chinopinda maitiro akawanda, zvichikonzera kuchinja kwepamusoro.Pane mhando mbiri huru dzeshanduko.
Mechanical shanduko: deformation;extrusion;kugaya.
Kuchinja kwemakemikari: phosphate layers (eg zinc phosphating kubatsira mukudhirowa);anti-corrosion compounds;chlorine, phosphorus kana sarufa inogona kunge iri mumafuta ekutonhora, saponification fluid, mafuta uye zvimwe zvinowedzera;pamusoro pekuputika kwekuona reagent.
Nzira yekuchenesa sei workpiece kuti uone kuchena kwepamusoro?
Kazhinji 95-99% mvura ine 1-5% yekuchenesa mumiriri inoshandiswa kuchenesa iyo workpiece, uye mhando yemvura yakakosha.Kusachena mumvura kwakadai se calcium, magnesium, sodium, potassium, uye chloride inogona kuramba iri pamusoro pechigadzirwa chebasa mushure mekuoma kuti chigadzire chivharo chekupararira, saka mvura yakasvibiswa ine conductivity inosvika 50 µS / cm inofanira kushandiswa kudzivirira. matambudziko panguva yekuchenesa.
Iyo aqueous yekuchenesa sisitimu ine mhando mbiri dzezvikamu: huru yekuchenesa mumiriri uye pamusoro inoshanda mumiriri.
Main yekuchenesa mumiririri: Iine inorganic kana organic zvinhu, senge alkali, phosphate, silicate, uye amine.Inogona kugadzirisa pH, kupa magetsi conductivity, uye saponify girisi.
Surface active agent: Iine organic zvinhu, zvakaita sealkyl benzene sulfonates uye fatty alcohol ethoxylates, uye inotamba mabasa ekunyungudutsa nekuparadzira mafuta nemafuta.
Iwo mana akakosha paramita ekunatsa kwemvura ndeyekuchenesa mvura, nguva yekuchenesa, tembiricha yekuchenesa uye nzira yekuchenesa.
1. Mvura yekuchenesa
Mvura yekuchenesa inofanira kuenderana nechikamu (rudzi rwezvinhu), kusvibiswa kwemazuva ano uye kunoteverapamusoro kurapwa.
2. Nguva yekuchenesa
Nguva yekuchenesa inoenderana nerudzi uye huwandu hwekusvibiswa uye inogona kutsamira pane yakapihwa kutevedzana kweiyo mutsara wekuchenesa kuitira kuti usapindirane neanotevera nhanho dzebasa.
3. Kuchenesa kupisa
Kupisa kwepamusoro kwekuchenesa kunoderedza viscosity yemafuta uye kunyungudutsa girizi, zvichiita kuti zvive nyore uye nyore kubvisa zvinhu izvi.
4. Nzira yekuchenesa
Mabasa akasiyana anounzwa kuburikidza nemidziyo yekuchenesa, senge: tank kutenderera, kufashama, kupfapfaidza, uye ultrasonic.Nzira yekuchenesa inoenderana nemhando uye chimiro chechikamu, kusvibiswa uye iripo yekuchenesa nguva.
Aya maparamita mana anofanira kugadziridzwa kune chaiwo mamiriro.Kuwedzera simba rekupa (mechanical, thermal kana kemikari) kana nguva yakareba yekurapa ichavandudza maitiro ekuchenesa.Mukuwedzera, kuyerera kwakasimba kwekuchenesa mvura kunovandudza maitiro ekuchenesa pakupisa kwakadzika.
Zvakakosha kucherechedza kuti zvimwe zvezvakasvibiswa zvakasungwa zvakanyanya uye hazvigone kubviswa nekuchenesa.Kusvibiswa kwakadaro kunogona kazhinji kubviswa chete nemaitiro akadai sekukuya, sandblasting, uye pre-oxidation.
