Amagama angukhiye: Ikhabethe le-sandblasting lomshini we-Junda
Umshini wokuqhumisa isihlabathi osetshenziswayo, udinga ukuqonda inqubo yawo, ukuze kwehliswe ukwehluleka kokusebenza kwemishini, ukukhuthaza ukusetshenziswa kwemishini ngendlela efanele, futhi ukuze kube lula kubasebenzisi abaningi ukuqonda ukusetshenziswa, inqubo enemininingwane elandelayo yethulwa ukuze iqondwe.
Okokuqala, ukwelashwa ngaphambi kwesikhathi.
Umshini wokuqhumisa isihlabathi endaweni yokusebenzela endaweni yokufafaza, ungqimba oluvikelayo lokufafaza (upende noma ezinye izinto ezinqanda ukubola), ingaphezulu le-workpiece kufanele liphathwe ngokungathí sina, okwaziwa ngele-pretreatment.
Izinga le-pretreatment lithinta ukunamathela, ukubukeka, ukumelana nomswakama kanye nokumelana nokugqwala kwengubo, ngoba ifilimu engcono yokugqoka (ungqimba) inamathele ebusweni obuhlanzwa ngokucophelela. Uma umsebenzi wokwelapha ungemuhle, ukugqwala kuzoqhubeka kusakazeka ngaphansi kokugqoka futhi kwenza i-coating flake off. Ngemuva kokuhlanza ngokucophelela indawo kanye nokulula okujwayelekile (i-sandpaper ye-manual noma ibhulashi) yokuhlanza i-workpiece, ngendlela yokuchayeka yokuqhathanisa ukuhlanganisa, ukuphila kungaba izikhathi ezingu-4-5. Ziningi izindlela zokuhlanza ingaphezulu, kodwa indlela evame ukuvunyelwa yilena: A. ukuhlanza i-solvent BC amathuluzi esandla D. amathuluzi kagesi
Ngalezi zindlela, indlela ngayinye inobubanzi bayo bokusebenza, kodwa kuzo zonke izindlela zokuhlanza indawo, indlela ye-sandblasting iphelele kakhulu, iphansi, ijwayelekile, indlela ebanzi, isizathu yilesi:
A, i-sandblasting ingcono kunezinye izindlela zokuhlanza ingaphezulu le-workpiece.
B, Ayikho enye inqubo ekuvumela ukuthi ukhethe phakathi kwamazinga okuhlanzeka amane abonwayo, amukelwa ngokujwayelekile.
Okwesibili, ukuqhunyiswa kwesihlabathi.
Umshini we-sandblasting usebenzisa umoya ocindezelwe njengamandla okwenza ugongolo lomjovo wesivinini esikhulu, okokusebenza kokufafaza (itshe lensimbi yethusi, isihlabathi se-quartz, isihlabathi sensimbi, isihlabathi solwandle, i-silicon carbide, njll.), njengendiza yejubane eliphezulu okufanele ibhekane nomhlabathi. , ukushintshwa kokubukeka kwangaphandle kwezingxenye, ngenxa yomphumela olimazayo kumthelela ongaphezulu kwendawo yokusebenza kanye nokusika, yenza uthole ukuhlanzeka nokungezwani okuhlukile kwendawo yokusebenza, yenza ingaphezulu lemishini ithuthukisiwe, ngakho-ke thuthukisa ukukhathala kwe-workpiece, ukwandisa ukunamathela phakathi kwayo kanye ne-coating, yandise ukuqina kwefilimu, kodwa futhi ihambisane nokugeleza kopende nokuhlobisa.
