Iziqondiso zohlelo lokusebenza lwemishini ye-sandblasting ehambayo
Umshini ohambayo we-sandblasting (ngokuvamile ubhekisela emshinini owomile we-sandblasting) uyinto eguquguqukayo kakhulu futhi ehambayo yokwelashwa kwendawo. Ngokungafani nemishini yokudubula edinga ukufakwa okugxilile, isebenzisa umoya ocindezelwe ukushayela i-abrasive ukuze ithinte phezulu. Izinzuzo eziyinhloko zemishini ephathwayo ye-sandblasting ilele "ekuhambeni" kanye "Nemisebenzi-eminingi", okuyenza ikwazi ukufinyelela ezindaweni okunzima ukufinyelela kuzo ngezisetshenziswa ezinkulu, ezingashintshi noma izakhiwo eziyinkimbinkimbi.
Izikhombisi-ndlela zohlelo lokusebenza eziyinhloko zemishini ye-sandblasting ehambayo:
I. I-Industrial Maintenance, Repair kanye{1}}ne-Anti{1}}corrosion Engineering (inkambu eyinhloko)
Ukwakhiwa okunqanda{0}ukugqwala kwezakhiwo ezinkulu
Imikhumbi namapulatifomu angasogwini: Ukususwa kokugqwala kanye nokususwa kukapende omdala wamagobolondo, amadekhi, amathangi e-ballast namakhebhini.
Amabhuloho: Ukususwa kokugqwala kanye nokuxebuka kwensimbi endala Amabhuloho namabhuloho anokhonkolo ukuze kulungiselelwe{0}}ukupendwa kabusha.
Amathangi okugcina nemikhumbi yokucindezela: Ukugcinwa nokuhlanza izindonga zangaphakathi nezingaphandle zamathangi okugcina aqondile/avundlile, amathangi ayindilinga, nemikhumbi esabelayo embonini ye-petroleum, amakhemikhali, negesi yemvelo.
Izakhiwo zensimbi:-Ukuphakama okuphezulu noma ukusebenza kwangaphandle okufana nemishayo yensimbi nezinsimbi ezimbonini, ezinkundleni zemidlalo, naseziteshini zikagesi.
Ukugcinwa kwemishini namapayipi
Amapayipi ezimbonini: Hlanza i-anti{0}}i-corrosion coating kanye nokugqwala odongeni olungaphandle lwamapayipi, futhi wenze{1}}ukwelashwa kwangaphambili kwama-welds.
Ama-boilers nezishintshisi zokushisa: Susa isikali, amadiphozithi ekhabhoni nama-oxides.
Imishini esindayo nezinto zokusebenza: Ukulungiswa kabusha okuyingxenye noma okuphelele kanye nokususwa kokugqwala kwenziwa endaweni yokuqala yezinto zokusebenza.
Ii. Ubunjiniyela Bezokwakha kanye Nokhonkolo
Ukwelashwa kwendawo ekhonkolo
Ukuhlanza kanye nokwenza roughening: Susa udaka oluntantayo, izendlalelo ezindala, amabala (afana namafutha, i-graffiti), kanye nokungcola kwamakhemikhali ebusweni bukakhonkolo.
Ukwelashwa kwe-roughening: Kuhlinzeka ngobulukhuni obudingekayo (ukwandisa ukunamathela) ukulungisa ukhonkolo, ukubeka ungqimba olungangeni manzi, ukuhlanganisa ukhonkolo okusha nokudala noma ukwakhiwa kwaphansi kwe-epoxy.
Ukubuyiselwa kwezakhiwo zomlando: Khipha ngobumnene izendlalelo eziguquliwe kanye nokungcola endaweni yezitini, amatshe nezinye izinto ngaphandle kokulimaza umzimba wokuqala.
Ubunjiniyela baphansi
Ukususwa kwama-coatings amadala nokwenza kusebenze indawo engaphezulu kukakhonkolo ezindaweni zokupaka, izindawo zokusebenzela zasefekthri, izindawo zokugcina, njll.
Iii. I-Special Surface Treatment kanye Nokucubungula Okuhle
Weld umthungo futhi ucubungula ukwelashwa kwangaphambili
Ngaphambi kokushisela, hlanza isikali se-oxide, ukugqwala namabala kawoyela ku-weld groove nezinhlangothi zombili ukuze uqinisekise ikhwalithi yokushisela.
Yenza ukuhlanza indawo kanye nokuqinisa ukuze kuhlanganiswe, ukufutha kanye nokunamathisela izingxenye zensimbi.
Ukucubungula okuhle nokucubungula iphethini
Ingilazi nomhlobiso wamatshe: isetshenziselwa ingilazi yokuqhwala kanye namaphethini okuqopha; Hlanza ingaphezulu letshe noma udale umphumela wakudala futhi omelene-nosheleli.
Ukwelashwa kwe-Metal surface brushing/matte: Ukwelashwa kwe-matte okufanayo noma okuthungwe kusetshenziswa emikhiqizweni efana nensimbi engagqwali ne-aluminium alloy.
Ukuhlanza isikhunta: Khipha izinsalela endaweni yenjoloba, ipulasitiki kanye{0}}nesikhunta esifayo.
Iv. Ukulungisa Okuphuthumayo kanye Nemisebenzi Yendawo Ekhethekile
Imisebenzi yasemkhathini evalekile: Imishini ephathwayo yokuqhumisa isihlabathi ingangena Ezikhaleni ezincane nezingenawo umoya ohlanzekile njengamathangi, amakhabhini, kanye nengaphakathi lamapayipi azohlanzwa.
Ukusebenza-okuphezulu kanye nokusebenza kwenkundla: Imishini ephathwayo ye-sandblasting ayisindi futhi inganyuselwa{1}}ezinkundleni zokusebenza eziphezulu noma ithuthelwe kumasayithi okwakha akude (njengokulungisa umbhoshongo we-wind turbine).
Ukucutshungulwa okunembayo kwendawo: Kulungele izimo lapho izindawo zasendaweni kuphela zidinga ukucutshungulwa ngaphandle kokuphazamisa isakhiwo sonke.
Izici eziyinhloko kanye nezinzuzo zemishini ye-sandblasting ehambayo
Ukuvumelana nezimo: Okokusebenza kuza namasondo noma kulula ukuhamba, ngaphandle kwesidingo sengqalasizinda engaguquki, ukufeza ngempela "ukushaya nomaphi lapho ukhomba khona".
Zijwayelanisa nezimo eziyinkimbinkimbi: Isibhamu sesifutho kanye nombozo zingabamba kalula izimo zejiyomethri eziyinkimbinkimbi njengamashidi, amakhona, kanye{0}nezindawo eziconvex.
Ukukhetha i-abrasive kubanzi: Ubulukhuni obuhlukile kanye nama-abrasives kasayizi wezinhlayiyana angakhethwa ngokuya ngezinto okufanele zilashwe futhi zicutshungulwe, njengalezi:
Ama-abrasives ensimbi: igrit yensimbi, isibhamu socingo lwensimbi (ukukhipha ukugqwala okukhulu).
Ama-abrasives amaminerali: isihlabathi se-quartz, isihlabathi se-slag (esinomnotho, kodwa sikhiqiza uthuli oluningi futhi sidinga ukulawulwa ngokuqinile).
Ama-abrasives ahambisana nemvelo: i-corundum ensundu, ubuhlalu bengilazi, amagobolondo e-walnut, izikhwebu zombila, isihlabathi sepulasitiki, njll. (esetshenziselwa ukucubungula kahle, ukuhlanza izindawo ezibucayi noma izindawo ezivuthayo).
Izinketho zenhloso ezimbili ezomile nezimanzi{0}ezitholakalayo: I-sandblasting emanzi ingacindezela ngempumelelo uthuli futhi ifanele indawo ezwela uthuli.
Umhlahlandlela Wokukhetha
Uma usebenzisana nezindawo ezinkulu zezindawo eziyisicaba futhi ufuna ukusebenza kahle kakhulu, khetha umshini oqhumayo wamaselula.
Uma kudingekile ukuphatha izakhiwo eziyinkimbinkimbi, ama-welds, izindawo ezinhle, noma ukwenza ukulungiswa kwendawo, futhi izimo zokusebenza ziyahlukahluka, kufanele kukhethwe umshini we-sandblasting ohambahambayo.
Umshini ohambayo wokuqhumisa isihlabathi, nokuguquguquka kwawo kanye nokuvumelana nezimo, usuphenduke "ithuluzi lokwelapha indawo yonke" elibaluleke kakhulu ekunakekeleni izimboni, ukulungisa umkhumbi, ukubuyisela izakhiwo kanye nokwakhiwa okukhethekile.
