Kungani eminye imikhiqizo eyimishini inezindawo ezinkulu zokuxebuka nokugqwala kopende ngemva kwesikhathi eside, kuyilapho eminye imikhiqizo ingahlala isikhathi eside kakhulu? Namuhla, ake sikhulume ngezinyathelo ezidingekayo zopende wezinga eliphezulu ngaphambi kokwakhiwa kopende - ukususwa kokugqwala !!!
1. Kungani sidinga ukwenza lesi sinyathelo ngopende wekhwalithi ephezulu emishinini yomhlaba wonke?
· Ukususwa kokugqwala, ukususwa kwe-slag yokushisela, nokususwa kopende omdala
Ngemva kokushisela nokucubungula, i-boom ngokuvamile inezindawo zokugqwala, isikali, i-welding slag, njll. Ukugaya okuvamile akusebenzi kahle futhi akukwazi ukususwa ngokuphelele. I-Sandblasting ingasusa ngempumelelo konke ukungcoliswa kwendawo futhi ibuyisele indawo ekhanyayo.
· Surface primer umsebenzi
Indawo encane eyi-concave ne-convex emagebhugebhu eshiywe ukuqhunyiswa kwesihlabathi inikeza "iphoyinti lokunamathela" ukwenza i-primer elandelayo iqine kakhudlwana futhi kungabi lula ukuwa.
· Yehlisa ukucindezeleka kwangaphakathi
Umthelela wesivinini esikhulu ungakhulula ingcindezi ethile eyinsalela ngemva kokushisela futhi unciphise ingozi yokuqhekeka kokukhathala.
2. Yini okufanele iqhume? Umhlahlandlela Wokukhetha Imidiya
Imidiya evamile ye-sandblasting ihlanganisa:
· Ukudubula kwesihlabathi/insimbi yensimbi: ukususwa kokugqwala okuqinile, ukusebenza kahle okuphezulu, kodwa izidingo zemishini ephezulu (ukuvuselela nokucubungula imidiya esindayo).
· Ubuhlalu bengilazi/i-aluminium sand/zirconium sand/garnet: amandla amaphakathi, kulula ukulawula umphumela wokuqala.
· Imidiya yepulasitiki noma yezinto eziphilayo (njengamagobolondo e-walnut, izikhwebu zommbila): ukuhlanza ngobumnene, akukho monakalo ku-substrate, elungele imininingwane noma izingxenye ezigogeke kalula.
3. Ukufafaza okomile vs. Ukufutha okumanzi: khetha okulungile ukuze uthole ukuthula kwengqondo
Ukufafaza okomile (Izinzuzo: ukususwa kokugqwala okusheshayo, izindleko eziphansi, ukusebenza kahle okuphezulu; Ukungalungi kanye nemikhawulo: uthuli olukhulu olundizayo, udinga ukunaka ukuvikelwa kwemvelo kanye nokukhipha umoya.)
Ukufafaza okumanzi (Izinzuzo: ukunciphisa uthuli okusobala, ukunciphisa ukulimala kwesihlabathi esindizayo kanye nokuphazamiseka okumile; imibimbi nemikhawulo: okokusebenza okuyinkimbinkimbi, izindleko eziphakeme kancane, ukuhlanzwa kwamanzi kudinga ukucatshangelwa okwengeziwe.)
Ukufafaza okomile kuvame ukusetshenziswa ezimbonini ze-boom, ezisebenza kahle futhi ezisheshayo; kodwa uma kunezidingo zokulawulwa kwemvelo nothuli, noma ngenkathi yemvula/indawo evaliwe, ukufutha okumanzi kungenye indlela ecophelela kakhulu.
4. Inqubo yokuqhunyiswa kwesihlabathi, asikho isinyathelo esigejiwe
1) Ukuvikelwa kokuvikela
Gcoba itheyiphu noma ibhodi lokuvikela ukuze uvikele izingxenye ezingafafaziwe, njengokusebenzelana kwamanzi namasongo okuvala.
2) Igumbi lokufutha lisendaweni futhi linomoya omuhle
Sebenzisa igumbi lokufutha noma indawo yokusebenza evulekile ukuze uqinisekise ukuthi uthuli lumuncwa ngesikhathi.
3) Setha amapharamitha
Lungisa ukucindezela ku-90-100 psi (cishe amabha angu-6-7), futhi ugcine isibhamu sokufutha cishe ngo-10-15cm sime phezulu phezulu.
4) Isiteji sokufafaza
Shanela ngokulinganayo futhi kancane, umboze kancane kancane, futhi ubhekane nokunqwabelana kothuli kalula namakhona afile; izinhlayiya zesihlabathi ziyathinta futhi zikhiphe isendlalelo esingcolile ngesivinini esikhulu.
5) Ukubuyiswa kwesihlabathi
Iningi lazo amasistimu omjikelezo ovaliwe, uthuli lokuhlunga nokusebenzisa kabusha imidiya ukunciphisa imfucuza.
6) Hlanza uthuli
Ngemva kokufafaza, sebenzisa umoya ocindezelweyo noma ukukhipha uthuli lwe-vacuum ukuze uqinisekise indawo ehlanzekile.
5. Izinzuzo eziningi zenqubo
· Ukusebenza okumangalisayo: umbala wokuqala wensimbi ungabuyiselwa emaminithini ambalwa, futhi ama-welds nokugqwala kungahlanzwa ngokushesha;
· Ukugqoka okuhlala isikhathi eside: indawo eqinile ithuthukisa ukumelana nokuxebuka futhi ukuqina kopende kuthuthukiswa kakhulu;
· Ukulungisa kalula: ukuphatha kalula ngemva kokuqhunyiswa kwesihlabathi kanye nokuthuthukisa ukumelana nokugqwala;
· I-Industrial aesthetics: ngemva kwe-sandblasting, ukuthungwa okufanayo kwe-"matte" kwethulwa, okubili okuthintekayo nokubonakalayo.
6. Amathiphu Okuphepha
I-Sandblasting ipholile, kodwa futhi inezingozi ezifihliwe:
· Ama-opharetha kudingeka agqoke izifihla-buso ezimelana nokucindezela, ukuvikela ukuzwa, namagilavu asindayo
· Sebenzisa imidiya engenabuthi ukuze ugweme izingozi zomsebenzi
· Izindawo ezinothuli kumele zibe zodwa, zingashi futhi zingaqhumi
• Shintsha njalo imibhobho: ukuguga kuzonciphisa ukusebenza kahle futhi kubangele ukumoshakala kwesihlabathi
Ukuqhunyiswa kwesihlabathi nokugaya ngesandla akunabutha komunye nomunye. Kunalokho, ukusetshenziswa okuhambisanayo kungathuthukisa ukusebenza kahle
Izincomo ezisebenzayo
· Isiteji sokucubungula: okokuqala sebenzisa ukugaya ngesandla ukuze ucubungule izindawo ze-welding spatter kanye nemiphetho emangelengele.
· Isigaba sokucubungula iqoqo: I-sandblasting isetshenziselwa izindawo ezinkulu, ezisebenza kahle futhi ezinokunamathela okuhle.
· Isiteji esihle: lungisa kahle futhi ugaye iziphambeko ezincane futhi, futhi ekugcineni ulawule uthuli futhi uhlanze indawo engaphezulu.
| Indlela | Izinzuzo | Ukubi |
| Ukugaya ngesandla (i-sandpaper /isondo lokugaya/i-angle grinder) | 1) Izindleko eziphansi kanye nemishini elula 2) Ifanele ukunqunywa kwendawo okunembe 3) Uthuli oluncane futhi kulula ukululawula | 1) Ukusebenza okuphansi kwezindawo ezinkulu 2) Ukusebenza kanzima nokuthatha isikhathi esiningi I-3) Ubulukhuni obungalingani bobuso buthinta ukunamathela kwefilimu kapende |
| Ukuqhuma kwesihlabathi (ukuqhuma okomile/ ukuqhunyiswa okumanzi) | 1) Ukusebenza kahle okuphezulu, kungasebenza ngokushesha izindawo ezinkulu 2) Ubuhwaba obungaphezulu bufana, bufika ezingeni le-micron I-3) Ukucubungula imininingwane enhle kakhulu, ama-welds namakhona afile angahlanzwa I-4) Yehlisa ukucindezeleka futhi uthuthukise ukunamathela kokugqoka okulandelayo | 1) Ukutshalwa kwezimali kwemishini yokuqala ephezulu 2) Ukufafaza okomile kukhiqiza uthuli oluningi futhi kudinga ukulawula uthuli 3) Ukufafaza okumanzi kuhamba kancane, kunezidingo eziphezulu zemvelo, kanye nokwelashwa kwesihlabathi okuyinkimbinkimbi |
| Ukuqhunyiswa kwesibhamu okuzenzakalelayo/ukuqhunyiswa kwesihlabathi | I-1) I-automation ephezulu, ukungaguquguquki okuhle, ukuthembela okuphansi okwenziwa ngesandla I-2) Ikhono lokucubungula ngobuningi ngokuphindaphindiwe ngaphandle kokukhathala okwenziwa ngesandla | 1) Izinto zokusebenza zinkulu futhi ziyabiza 2) Ingase ingambozi ngokugcwele izakhiwo eziyinkimbinkimbi/ezinkulu 3) Inokuguquguquka okungekuhle futhi ayilungele imisebenzi yesikhashana noma emincane |
Okwengalo yomgodi, i-sandblasting iwukuhlanza okusebenza kahle kakhulu, okusebenzayo futhi okumelana nokugqwala. Umongo uwukuthi: ukufafaza izindawo zokugqwala + ukudala indawo emagebhugebhu + ukwenza ngcono ukunamathela kukapende, kwengezwe ngokufafaza okomile/okumanzi, ukukhetha indawo elungile kanye nokuvikela ukuphepha. Inqubo iyamangalisa.
Lesi sinyathelo sithuthukisa ikhwalithi nokuqina kwayo yonke inqubo yokulingisa/yokukhiqiza. Uma ufuna ukwazi okwengeziwe ngemodeli yemishini ye-sandblasting, ividiyo yokwakha noma izindleko zempahla, ungaqhubeka nokuxoxa!
