Kushandisa Dzimwe Nzira MuKugezera Kwekugadzirira Kubvisa Mafuta

Kuchenesa kunoshanda kune yakaderera, kunyangwe tembiricha yakadzikama, inogoneka uye inogadzira nzvimbo yebasa yakachengeteka uye inoderedza kudiwa kwesimba.

Mubvunzo: Tave tichishandisa chigadzirwa chakafanana chekubvisa mafuta kwemakore mazhinji uye chinoshanda zvakatinakira kwatiri, asi chine hupenyu hupfupi hwekugeza uye inoshanda kutenderera 150oF.Pashure unenge mwedzi, zvikamu zvedu hazvichacheneswi zvinobudirira.Ndedzipi dzimwe nzira dziripo?

A: Kunyatsochenesa nzvimbo yepasi kwakakosha mukuwana chikamu chemhando yepamusoro chakapendwa.Pasina kubvisa ivhu (ingava organic kana inorganic), zvakaoma zvikuru kana kuti hazvibviri kuumba chifukidzo chinodiwa pamusoro.Indasitiri shanduko kubva kune phosphate inoshandura coatings kusvika kune yakagadzikana yakaonda-firimu mabhanhire (akadai sezirconium uye silanes) yakawedzera kukosha kwekuenderana kwe substrate kuchenesa.Kukanganisa mumhando yepretreatment kunobatsira pakukanganisa kwependi inodhura uye mutoro pakushanda zvakanaka.

Vagezi vemazuva ese, vakafanana neako, vanowanzo shanda patembiricha yepamusoro uye vanowanzova nemafuta akaderera ekurodha.Aya makuchenesa anopa kushanda kwakakwana kana kutsva, asi kushanda kwekuchenesa kunowanzodzikira nekukurumidza, zvichiita kuti hupenyu hupfupi hwekugeza, hurema huwedzere uye mari yepamusoro yekushanda.Nehupenyu hupfupi hwekugeza, kuwanda kwezvipfeko zvitsva kunowedzera, zvichikonzera kuraswa kwemarara kwakanyanya kana mari yekuchenesa mvura.Kuchengetedza sisitimu pamatembiricha epamusoro ekushanda, huwandu hwesimba hunodiwa hwakakura kudarika tembiricha yakaderera.Kurwisa iyo yakaderera-oiri mamiriro ekugona, midziyo yekubatsira inogona kushandiswa, izvo zvinoguma nekuwedzera mari uye kugadzirisa.

Vachenesa vechizvarwa chitsva vanokwanisa kugadzirisa kusakwana kwakawanda kwakabatana neanowanzo kuchenesa.Kugadziridza uye kuisirwa kweakanyanya kuomesesa surfactant mapakeji anopa akawanda mabhenefiti kune vanonyorera - kunyanya kuburikidza nehupenyu hwakareba hwekugezesa.Mamwe mabhenefiti anosanganisira kuwedzera kubereka, kurapwa kwemvura yetsvina uye kuchengetedza makemikari, uye kuvandudza muchikamu chemhando nekuchengetedza kushanda kwakagadzikana kwenguva yakareba.Kuchenesa kunoshanda pane tembiricha yakaderera, kunyangwe tembiricha yepakati, inogoneka.Izvi zvinogadzira nzvimbo yakachengeteka yebasa uye inoderedza simba rinodiwa, zvichiita kuti mari yekushanda ivandudzwe.

Mubvunzo: Zvimwe zvezvikamu zvedu zvine welds uye laser cuts izvo zvinowanzokonzera kukanganisa kwakawanda kana kugadzirisa zvakare.Parizvino, isu tinoregeredza nzvimbo idzi nekuti zvinonetsa kubvisa chiyero chakaumbwa panguva yewelding uye laser yekucheka.Kupa vatengi vedu mhinduro yepamusoro inoita kuti tiwedzere bhizinesi redu.Tingaita sei izvi?

A: Zviyero zveInorganic, zvakaita semaokisi akaumbwa panguva yewelding uye laser yekucheka, zvinokanganisa iyo yese pretreatment maitiro kubva kushanda nemazvo.Kuchenesa organic ivhu padhuze ne welds uye laser kucheka kunowanzo kuve kwakashata, uye kuumbwa kweiyo yekuchinjisa coating hakuitike pane inorganic zviyero.Kune pendi, inorganic zviyero zvinounza nyaya dzinoverengeka.Kuvepo kwechikero kunotadzisa pendi kunamatira kune hwaro simbi (zvakadai semajasi ekushandura), zvichikonzera kukora nguva isati yakwana.Pamusoro pezvo, iyo silica inclusions yakaumbwa panguva yewelding process inorambidza kufukidzwa kuzere mukushandisa ecoat, nekudaro zvichiwedzera mukana wekuora nguva isati yakwana.Vamwe vanyoreri vanoedza kugadzirisa izvi nekuisa pendi yakawanda pazvikamu, asi izvi zvinowedzera mutengo uye hazvigaro kuvandudza kupikisa kwependi munzvimbo dzakaiswa.

Vamwe vanonyorera vanoshandisa nzira dzekubvisa weld nelaser sikero, senge acid pickles uye mechanical nzira (media blasting, grinding), asi pane zvakakomba zvakaipira zvine chekuita neimwe yeidzo.Acid pickles inoisa njodzi yekuchengetedza kune vashandi, kana isingashandiswe nemazvo kana nematanho akakodzera uye zvekuzvidzivirira nazvo.Ivo zvakare vane hupenyu hupfupi hwekugezesa sezvo zvikero zvinovaka mumushonga, izvo zvinofanirwa kuve zvakaraswa kana kutumirwa kure-nzvimbo kunoraswa.Mukutarisa kuputika kwenhau, kubviswa kwe weld uye laser chiyero kunogona kushanda mune mamwe maapplication.Nekudaro, zvinogona kukonzera kukuvadzwa kweiyo substrate pamusoro, ivhu rekuisa pamuviri kana tsvina midhiya ikashandiswa uye ine mutsara-we-kuona nyaya kune yakaoma chikamu geometries.Kukuya nemaoko kunokuvadza uye kunoshandura nzvimbo yepasi, haina kunaka kune zvidimbu zvidiki uye injodzi huru kune vanoshanda.

Kubudirira kwemakemikari ekudzikisa tekinoroji kwakawedzera mumakore achangopfuura, sezvo vanyoreri vanoona nzira yakachengeteka uye inodhura zvakanyanya yekuvandudza kubviswa kweokisijeni iri mukati mekutevedzana kwekutanga.Mazuva ano descaling chemistries inopa yakakura kwazvo maitiro ekuita zvakasiyana-siyana (kushanda mune zvese kunyudza uye kupfapfaidza zvikumbiro);hazvina zvinhu zvakawanda zvine ngozi kana zvinodzorwa, senge phosphoric acid, fluoride, nonylphenol ethoxylates uye yakaoma chelating agents;uye anogona kunge aine akavakirwa-mukati surfactant mapakeji kutsigira kunatsiridza kuchenesa.Kufambira mberi kunoonekwa kunosanganisira kusarerekera pH decalers yekuvandudzwa kwekuchengetedzwa kwevashandi uye kuderedzwa kwekukuvara kwemidziyo kubva pakufumurwa kune corrosive acids.
