Sei zvimwe zvigadzirwa zvemakina zvine nzvimbo dzakakura dzependi inosvuura uye ngura mushure menguva refu, nepo zvimwe zvigadzirwa zvichigona kugara zvakanyanya? Nhasi, ngatitaurei pamusoro pematanho anodiwa ependi yemhando yepamusoro isati yavakwa pendi - kubvisa ngura !!!
1. Nei tichifanira kuita danho iri remhando yepamusoro pendi pamichina yepasi rose?
· Kubvisa ngura, welding slag kubviswa, nekubvisa pendi yekare
Mushure mekugadzira uye kugadzirisa, iyo boom inowanzove ine ngura mavara, chiyero, welding slag, nezvimwe zvakabatanidzwa. Kugaya kwakajairika hakushandi uye hakugone kubviswa zvachose. Sandblasting inogona kunyatsobvisa kusvibiswa kwese kwepasi uye kudzoreredza nzvimbo yakapenya.
· Surface primer basa
Iyo diki yakakombama uye yakakombama nzvimbo yakasiiwa nejecha inopa "adhesion anchor point" kuita kuti chinotevera chive chakasimba uye kuti chisava nyore kudonha.
· Deredza kushushikana kwemukati
High-speed effect inogona kusunungura imwe yakasara kushushikana mushure mekugadzira uye kuderedza njodzi yekuneta kutsemuka.
2. Chii chekuputika? Media Selection Guide
Yakajairika sandblasting media inosanganisira:
· Simbi jecha / simbi pfuti: inorema-basa ngura kubvisa, yakakwirira kunyatsoshanda, asi yakakwirira midziyo zvinodiwa (kudzokorodza uye kugadzirisa inorema midhiya).
· Girazi mabheji / aluminium jecha / zirconium jecha / garnet: simba repakati, nyore kudzora primer mhedzisiro.
· Purasitiki kana organic midhiya (senge walnuts shells, chibage cobs): zvinyoro kuchenesa, hapana kukuvadzwa kune substrate, inokodzera ruzivo kana zvikamu zvinoremara nyore.
3. Dry spraying vs. wet spraying: sarudza yakakodzera kuti uwane rugare rwepfungwa
Dry spraying (Zvakanakira: kukurumidza kubvisa ngura, mutengo wakaderera, kushanda zvakanaka; Kuipa uye zvisingakwanisi: huru inobhururuka huruva, inoda kutarisisa kuchengetedza kwezvakatipoteredza uye kufefetedza.)
Kupfapfaidza kunyorova (Zvakanakira: kuderedzwa kweguruva kuri pachena, kuderedza kukuvara kwejecha rinobhururuka uye kukanganiswa kwakamira; Zvakashata uye zvinogumira: midziyo yakaoma, mutengo wakakwira zvishoma, kurapwa kwemvura kunoda kumwe kutariswa.)
Dry spraying inowanzoshandiswa mumafekitari e-boom, iyo inoshanda uye inokurumidza; asi kana pane zvinodiwa pakudzora kwezvakatipoteredza uye guruva, kana mumwaka wekunaya kwemvura/yakavharwa, kupfapfaidza nyoro ndiyo imwe nzira ine hunyanzvi.
4. Sandblasting process, hapana danho rakapotsa
1) Kudzivirira kudzivirira
Isa tepi kana bhodhi rekudzivirira kuchengetedza zvikamu zvisina-sprayed, senge hydraulic interfaces uye kuvhara zvindori.
2) Imba yekupfapfaidza iri panzvimbo uye ine mhepo yakanaka
Shandisa kamuri yekupfapfaidza kana nzvimbo yakavhurika yebasa kuti uve nechokwadi chekuti huruva inosvetwa nenguva.
3) Seta parameters
Gadzirisa kumanikidza ku90-100 psi (inenge 6-7 bar), uye chengeta pfuti yekupfapfaidza inenge 10-15cm yakatwasuka kumusoro.
4) Kupfapfaidza danho
Tsvaira zvakaenzana uye zvishoma nezvishoma, vhara zvishoma nezvishoma, uye gadzirisa kuunganidza guruva nyore uye makona akafa; jecha particles inokanganisa uye bvisa iyo yakasvibiswa layer nekumhanya kukuru.
5) Kupora kwejecha
Mazhinji acho akavharwa-yedunhu kutenderera masisitimu, sefa guruva uye kushandisazve midhiya kuderedza tsvina.
6) Guruva rakachena
Mushure mekupfapfaidza, shandisa mhepo yakamanikidzwa kana vacuum kubvisa guruva kuti uve nechokwadi chekuti nzvimbo yakachena.
5. Zvikomborero zvakawanda zvemuitiro
· Kubudirira kunoshamisa: ruvara rwepakutanga rwesimbi runogona kudzorerwa mumaminitsi mashomanana, uye welds uye ngura zvinogona kukurumidza kucheneswa;
· Kupfeka kwekugara kwenguva refu: iyo yakaoma nzvimbo inovandudza kuramba kusvuura uye kusimba kwepende kunowedzera zvakanyanya;
· Kugadzirisa kuri nyore: manejimendi ari nyore mushure mekuputika kwejecha uye nekuvandudza corrosion kuramba;
· Industrial aesthetics: mushure mekuputika kwejecha, yunifomu ye "matte" yakagadzirwa, iyo inobata uye inoonekwa.
6. Mazano Okuchengetedza
Sandblasting inotonhorera, asi ine zvakare yakavanzika njodzi:
· Vashandi vanofanirwa kupfeka masiki anodzivirira kunzwa, uye magirovhosi anorema
· Shandisa zvisina muchetura media kudzivirira njodzi dzebasa
· Nzvimbo dzinonyanya guruva dzinofanirwa kunge dziri kwadzo, dzisingaite moto, uye dzisingaputika
· Gara uchitsiva ma nozzles: kupfeka uye kubvaruka kunoderedza kugona uye kukonzera kutambisa jecha
Sandblasting uye manual grinding hazvisi kurwisana kune mumwe nemumwe. Pane kudaro, kushandiswa kwekuwedzera kunogona kuvandudza kushanda
Mazano anoshanda
· Rough processing stage: tanga shandisa manual grinding kugadzirisa welding spatter nzvimbo uye rough edges.
· Batch processing stage: Sandblasting inoshandiswa kune nzvimbo huru, iyo inoshanda uye ine yakanaka adhesion.
· Yakanaka nhanho: gadzirisa uye kukuya zvirema zvidiki zvakare, uye pakupedzisira tonga guruva uye chenesa pamusoro.
| Nzira | Zvakanakira | Zvakaipa |
| Kukuya nemaoko (sandpaper /kukuya vhiri/angle grinder) | 1) Mutengo wakaderera uye midziyo iri nyore 2) Inokodzera kuchekwa chaiko kwenzvimbo 3) Guruva shoma uye nyore kudzora | 1) Kushanda kwakaderera kwenzvimbo huru 2) Kutora nguva uye kushanda nesimba, kushanda nesimba 3) Kusaenzana kwepamusoro roughness inokanganisa pendi film adhesion |
| Kuputika kwejecha (kuputika kwakaoma / kuputika kwemvura) | 1) Kushanda kwepamusoro, kunogona kukurumidza kugadzirisa nzvimbo huru 2) Kushata kwepamusoro kwakafanana, kusvika ku micron level 3) Yakanakisa dhizaini kugadzirisa, welds uye akafa makona anogona kucheneswa 4) Deredza kushushikana uye kuvandudza kunotevera kwekunamatira kunamatira | 1) Yakakwira yekutanga michina mari 2) Dry spraying inogadzira huruva yakawanda uye inoda kudzora guruva 3) Kupfapfaidza kwemvura kunononoka, kune zvinodiwa zvakanyanya kwezvakatipoteredza, uye kurapwa kwejecha kwakaoma |
| Mechanical otomatiki kupfura kuputika / kuputika kwejecha | 1) Yakakwira otomatiki, yakanaka kuenderana, yakaderera bhuku revimbo 2) Kugona kugadzirisa muhuwandu hwakawanda kakawanda pasina kuneta kwemaoko | 1) Midziyo yakakura uye inodhura 2) Inogona kunge isingafukidze zvakakwana zvimiro zvakaoma / zvakakura 3) Iine hurombo hunyoro uye haina kukodzera kumabasa enguva pfupi kana madiki |
Kune ruoko rwekuchera, sandblasting inoshanda zvakanyanya, inoshanda uye inodzivirira kuchenesa. Mhedzisiro ndeye: kupfapfaidza kubva ngura mavara + kugadzira nzvimbo yakaoma + kuvandudza pendi yekunamatira, inowedzerwa nekupfapfaidza kwakaoma / kunyorova, kusarudza svikiro rakakodzera uye kuchengetedza kuchengetedza. Maitiro acho anoshamisa.
Iyi nhanho inovandudza kunaka uye kusimba kweiyo yese yekukanda / kugadzira maitiro. Kana iwe uchida kuziva zvakawanda nezve sandblasting mudziyo modhi, vhidhiyo yekuvaka kana mutengo wezvinhu, unogona zvakare kuenderera mberi nekutaura!
