Izici Eziyinhloko Zokuqhunyiswa Kwesanti

——Ukuqhuma kwesihlabathi okuyinhloko kusuka ezicini ezinhlanu

I-Sandblasting iyinqubo yokwelashwa kwendawo ngokuqhubeza izinhlayiya ezilumayo ngesivinini esikhulu ukuya kuyo. Kuyindlela elula futhi ephezulu ephumelelayo yokudala ubulukhuni obudingekayo.Kodwa-ke, abantu abaningi bangase bangazi ukuthi bangathola kanjani ukuqhunyiswa okungcono kakhulu. Kulokhu, ake sifunde kabanzi mayelana nezici ezibalulekile ze-sandblasting.

Isici 1: Umoya ocindezelwe

Inqubo ye-sandblasting ngokuvamile ihlanganisa izingxenye ezintathu eziyinhloko, okuyi-compressor yomoya, izinhlayiya eziqhumayo, kanye nombhobho. Umoya ocindezelwe, njengesinyathelo sokuqala, ubalulekile ekuqhubekiseni ama-abrasives.Izinga layo linqunywa ngokuyinhloko yizici ezimbili: umfutho womoya kanye nekhwalithi yomoya. Isidingo esihlukile sobuqhwaga sidinga umfutho womoya ofanele. Indawo okunzima ukuyihlanza idinga ukucindezela okuphezulu, kuyilapho ethambile idinga ukucindezela okuphansi ukuze kuncishiswe umphumela wamandla.Izinga lomoya lisho ukuhlanzeka komoya okungakalwa yi-clei-aningidivayisi yokuthola umoya ocindezelweyo. Ngaphezu kwalokho, kukhona nemishini yokomisa yokukhipha umswakama emoyeni.

Isici sesi-2: Ama-Abrasives 

Ukuqhuma kwe-Abrasive kunezinhlelo eziningi zokusebenza, ngasinye sazo esidinga ukusetshenziswa kwezinhlobo ezahlukene zezinhlayiya ezilumayo, ezaziwa ngokuthi imidiya eqhumayo.Ama-abrasives ajwayelekile achazwe ngezansi.

I-aluminium oxide: I-Aluminium oxide ihlanganisa ubulukhuni bayo obuphezulu namandla. Kuyimidiya ehlala isikhathi eside eyi-angular yokubhala ngokushesha eholela kuphethini yehange yephrofayili engaphezulu.

Ubuhlalu Bengilazi：Yingilazi ye-soda-lime eyindilinga. Uma kuqhathaniswa nezinye izinto, ingilazi ayinalo ulaka njengemidiya eqhumayo njenge-steel shot noma i-silicon carbide. Ama-abrasives obuhlalu bengilazi anengcindezi encane ngaphezulu ukuze akhiqize ukuqedwa kohlobo lwe-matte ekhanyayo ne-satin.

Ipulasitiki: Kuyinto abrasive ethambile okungukuthiezifanele yokuhlanza isikhunta noma izingxenye zepulasitiki.

I-Silicon Carbide: Iwumsebenzi onzima kakhulu wokugwaza otholakalayo ulingana kahle ekuhlanzeni indawo eyinselele kakhulu.

I-Steel Shot & Grit: Kuyi-abrasive esebenza kahle kakhulu ngenxa yobulukhuni bayo kanye nokusetshenziswa kabusha okuphezulu.

Amagobolondo eWalnut: Kuyimpahla yemvelo enobulukhuni eyenziwe ngamagobolondo e-walnut echotshoziwe, eqinile yama-abrasives athambile.

Isici sesi-3: Umbhobho

Umbhobho udlala indima ebalulekile njengengxenye yokugcina ekuqhumeni, okuthinta kakhulu umphumela wokuqeda ongaphezulu.Ngokwezimo ezihlukene zokusetshenziswa kanye nezidingo zokwelashwa kwendawo, sidinga ukukhetha ezifaneleka kakhului-sandblastingumlomo, othkungenjalo,umphumela uzoncipha kakhulu.

Usayizi

Ngamunyeuhlobo lweumlomo wombhobho unosayizi ohlukiles. Khetha i-nozzle ene-bore encane kakhulu futhi uzoyenzaukumosha ingcindezi, kuyilapho uma tey mkhulu,uzoswela ingcindezi yokuqhuma ngendlela ekhiqizayo.

Indaba

Izinto ezintathu ezaziwa kakhulu ezisetshenziswa namuhla ku-blast nozzle yi-boron carbide, i-silicon carbide, kanyei-tungsten i-carbide. Imibhobho ye-Boron carbide ifaka ukuqina okukhulu, okungasindi, kanye nokumelana okuhle nokuhunyazwa. Imibhobho ye-silicon carbide ifana ne-boron carbide. Inokusebenza okuphansi kokumelana nokugqoka.Imibhobho ye-tungsten carbide iqinile futhi inesakhiwo esizinzile esidinga ukulungiswa okuncane, kuyilapho isindayo.

Uhlobo

I-Venturi Nozzle: Kwadalwa beqe ku umgomo weI-Venturi Eumphumela okungukuthi ukuncipha komfutho woketshezi oluholela ekwandeni koketshezi’s isivinini. Ngakho-ke, itsukwakheka kwephethini yokuqhuma kuyenza isebenze kahle ekuqhumeni.

I-Sight Bore Nozzle:Kwakha iphethini yokuqhuma okuqinile lokho isesetshenziswa lapho izingxenye ezincane noma ukuqhunyiswa okulula kuyadingeka.

Umbhobho wokungeniswa kwamanzi: Iwuhlobo lombhobho womabili atholakala ekuqhumeni okomile nasekuqhunyisweni okumanzi. Uma kuqhathaniswa namanye ama-nozzles, inobungane empilweni yokucindezela uthuli.

I-Internal Pipe Blast Nozzle: Injaloesetshenzisiwe ukusula udonga lwangaphakathi lwepayipi eliqhuma ngephethini yekhoni efakwe amathuluzi ahlukahlukene njengamasethi wamakholomu, inqola emaphakathi, njll.

I-Nozzle egobile: Isebenza nge-engeli egobile yokuphuma, ekhuthaza ukufinyelela kokuqhunyiswa kwesihlabathi ezindaweni eziqinile noma ezilingana kahle.

Isici sesi-4: Isimo Sobuso

Okunye ukuthungwa kwendawo kuqinile futhi kudinga amandla amakhulu ukuze kuguqulwe iphrofayili engaphezulu. Ezinye izindawo zintekenteke kakhulu,dingaingumthelela omncane.

Isici sesi-5: Ukukhanyisa

Kunezimo ezahlukahlukene zohlelo lokusebenza lwe-sandblasting. Kungaba ngaphakathi noma ngaphandle. Okunye ukuqhunyiswa kwesihlabathi kuzokwenziwa kukhabhinethi yokuqhunyiswa kwesihlabathi. Kulokhu, opharetha udinga ukulungiselelaizinga elihleukukhanya lapho kwenziwa i-sandblasting ibe ngconoqaphelaisimo se-sandblasting.

Nquma ukwakheka kwalezi zakhi ezinhlanu ngokwezidingo zakho ze-sandblasting, futhi uzothola umphumela omuhle wokuqhumisa isihlabathi.
