Kodi nchifukwa ninji zinthu zina zamakina zimakhala ndi malo aakulu osendeza utoto ndi dzimbiri pakapita nthawi yaitali, pamene zinthu zina zimakhala zolimba kwambiri? Lero, tiyeni tikambirane njira zofunika zopangira utoto wapamwamba kwambiri musanapange utoto - kuchotsa dzimbiri !!!
1. N’cifukwa ciani tifunika kucita zimenezi kuti tipeze penti yamtengo wapatali pa makina a padziko lonse?
· Kuchotsa dzimbiri, kuwotcherera slag, ndi kuchotsa utoto wakale
Pambuyo kuwotcherera ndi kukonza, boom nthawi zambiri imakhala ndi mawanga a dzimbiri, sikelo, kuwotcherera slag, etc. Kupera wamba sikuthandiza ndipo sikungachotsedwe kwathunthu. Kuphulika kwa mchenga kumatha kuchotsa bwinobwino kuipitsidwa kwapadziko lonse ndikubwezeretsanso kuwala.
· Surface primer ntchito
Malo ang'onoang'ono opindika ndi otambalala omwe amasiyidwa ndi kuphulika kwa mchenga amapereka "malo omatira" kuti choyambira chotsatira chikhale cholimba komanso kuti chisagwe.
· Chepetsani nkhawa zamkati
Kuthamanga kwambiri kumatha kumasula kupsinjika kotsalira pambuyo pa kuwotcherera ndikuchepetsa chiopsezo cha ming'alu ya kutopa.
2. Kuphulitsa chiyani? Media Selection Guide
Ma media odziwika bwino a sandblasting ndi awa:
· Mchenga wachitsulo / chitsulo chowombera: kuchotsa dzimbiri lolemera kwambiri, kuchita bwino kwambiri, koma zofunikira za zida (zobwezeretsanso ndi kukonza media zolemera).
· Mikanda yagalasi / mchenga wa aluminiyamu / mchenga wa zirconium / garnet: mphamvu yapakatikati, yosavuta kuwongolera zoyambira.
Pulasitiki kapena organic media (monga zipolopolo za mtedza, zitsonoro za chimanga): kuyeretsa mofatsa, osawononga gawo lapansi, oyenera tsatanetsatane kapena ziwalo zopunduka mosavuta.
3. Kupopera mbewu mouma motsutsana ndi kupopera mbewu mankhwalawa monyowa: sankhani koyenera kuti mukhale ndi mtendere wamumtima
Kupopera mbewu mankhwalawa youma (Ubwino: kuchotsa dzimbiri mwachangu, kutsika mtengo, kugwiritsa ntchito bwino kwambiri; Zoyipa ndi zolephera: fumbi lalikulu lowuluka, liyenera kulabadira kuteteza chilengedwe ndi mpweya wabwino.)
Kupopera mbewu mankhwalawa monyowa (Ubwino: kuchepetsa fumbi lodziwikiratu, kuchepetsa kuvulala kwa mchenga wowuluka ndi kusokonezedwa ndi ma static; Zoyipa ndi zolephera: zida zovuta, zokwera mtengo pang'ono, kuthira madzi kumafunikira kuganiziridwanso.)
Kupopera mbewu mankhwalawa nthawi zambiri kumagwiritsidwa ntchito m'mafakitale a boom, omwe ndi othandiza komanso othamanga; koma ngati pali zofunikira pakuwongolera chilengedwe ndi fumbi, kapena nyengo yamvula/yotsekedwa, kupopera mbewu mankhwalawa ndi njira yosamala kwambiri.
4. Sandblasting ndondomeko, palibe sitepe anaphonya
1) Kuteteza chitetezo
Ikani tepi kapena bolodi lotchinga kuti muteteze mbali zosapopera, monga ma hydraulic interfaces ndi mphete zosindikizira.
2) Chipinda chotsitsirapo chili pamalo ake komanso mpweya wabwino
Gwiritsani ntchito chipinda chopopera kapena malo otseguka kuti mutsimikizire kuti fumbi layamwa munthawi yake.
3) Khazikitsani magawo
Sinthani kukakamiza kukhala 90-100 psi (pafupifupi 6-7 bar), ndipo sungani mfuti yopopera pafupifupi 10-15cm yolunjika pamwamba.
4) Popopera siteji
Sesani mofanana ndi pang'onopang'ono, kuphimba pang'onopang'ono, ndikuthana ndi kusonkhanitsa fumbi mosavuta ndi ngodya zakufa; mchenga particles kukhudza ndi kupukuta zakhudzana wosanjikiza pa mkulu liwiro.
5) Kubwezeretsa mchenga
Ambiri aiwo ndi otsekedwa-ozungulira machitidwe, fumbi losefera ndikugwiritsanso ntchito media kuti muchepetse zinyalala.
6) Fumbi loyera
Mukamaliza kupopera mbewu mankhwalawa, gwiritsani ntchito mpweya woponderezedwa kapena kuchotsa fumbi la vacuum kuti pakhale malo oyera.
5. Zopindulitsa zambiri za ndondomekoyi
· Kuchita bwino kodabwitsa: mtundu woyambirira wachitsulo ukhoza kubwezeretsedwanso mumphindi zochepa, ndipo ma welds ndi dzimbiri amatha kutsukidwa mwachangu;
· Kupaka kwautali: malo okhwima amathandizira kukana peeling ndipo kulimba kwa utoto kumakulitsidwa kwambiri;
Kukonza kosavuta: kuwongolera kosavuta pambuyo pa kuphulika kwa mchenga ndikuwongolera kukana kwa dzimbiri;
· Industrial aesthetics: pambuyo pa sandblasting, mawonekedwe a yunifolomu "matte" amaperekedwa, omwe ali owoneka bwino komanso owoneka bwino.
6. Malangizo a Chitetezo
Kuphulika kwa mchenga ndikozizira, koma kulinso ndi zoopsa zobisika:
· Ogwira ntchito amayenera kuvala zotchinga zosagwira ntchito, zoteteza kumva, ndi magolovesi olemera
- Gwiritsani ntchito zoulutsira mawu zopanda poizoni kuti mupewe ngozi zapantchito
• Malo okhala ndi fumbi ayenera kukhala paokha, osawotcha, komanso osaphulika
Nthawi zonse sinthani ma nozzles: kung'ambika kumachepetsa mphamvu ndikuwononga mchenga
Kuwombera mchenga ndi kugaya pamanja sikumadana. M'malo mwake, kugwiritsa ntchito kowonjezera kumatha kupititsa patsogolo luso
Malangizo othandiza
· Waukali processing siteji: choyamba ntchito Buku akupera pokonza kuwotcherera spatter madera ndi m'mbali akhakula.
· Gawo lopangira ma batch: Kuphulika kwa mchenga kumagwiritsidwa ntchito kumadera akuluakulu, komwe kumakhala kothandiza komanso kumamatira bwino.
· Gawo labwino: konzani bwino ndikugayanso zolakwika zazing'ono, ndipo pamapeto pake samalirani fumbi ndikuyeretsa pamwamba.
| Njira | Ubwino wake | Zoipa |
| Kupera pamanja (sandpaper / gudumu lopera / chopukusira) | 1) Zida zotsika mtengo komanso zosavuta 2) Yoyenera kukonza ndendende komweko 3) Fumbi lochepa komanso losavuta kuwongolera | 1) Kuchita bwino kochepa kwa madera akuluakulu 2) Kugwira ntchito molimbika komanso kuwononga nthawi 3) Kusakhazikika kwapamwamba kumakhudza kumamatira kwa filimu ya utoto |
| Kuphulika kwa mchenga (kuphulika kowuma / kuphulika konyowa) | 1) Kuchita bwino kwambiri, kumatha kukonza madera akuluakulu mwachangu 2) Ukali wapamtunda ndi wofanana, mpaka mulingo wa micron 3) Kukonza bwino kwambiri, ma welds ndi ngodya zakufa zitha kutsukidwa 4) Chepetsani kupsinjika ndikuwongolera zomatira zomatira | 1) Ndalama zoyambira zida zapamwamba 2) Kupopera mbewu mankhwalawa kumatulutsa fumbi lambiri ndipo kumafuna kuwongolera fumbi 3) Kupopera mbewu mankhwalawa kumachedwa, kumakhala ndi zofunikira zachilengedwe, komanso chithandizo chamchenga chovuta |
| Kuwombera kwachimake / kuwomba mchenga | 1) Makina apamwamba kwambiri, kusasinthika kwabwino, kudalira pang'ono kwamanja 2) Kutha kukonza mochuluka mobwerezabwereza popanda kutopa kwamanja | 1) Zida ndi zazikulu komanso zodula 2) Itha kubisa zonse zovuta / zazikulu 3) Ili ndi kusinthasintha kosasinthika ndipo siyenera kugwira ntchito zosakhalitsa kapena zazing'ono |
Kwa mkono wofukula, sandblasting ndi njira yabwino kwambiri, yothandiza komanso yosagwira dzimbiri. Pachimake ndi: kupopera madontho a dzimbiri + kupanga malo owoneka bwino + kukonza zomatira utoto, kuwonjezeredwa ndi kupopera mbewu mankhwalawa kowuma / konyowa, kusankha njira yoyenera ndi chitetezo. Njirayi ndi yodabwitsa.
Sitepe iyi imapangitsa kuti ntchito zonse zopanga/kupanga zikhale zolimba komanso zolimba. Ngati mukufuna kudziwa zambiri za mtundu wa zida za sandblasting, kanema yomanga kapena mtengo wazinthu, mutha kupitiliza kucheza!
