Umnyango wezobuchwepheshe we-TAA ukholelwa ukuthi ukunakekelwa kwangaphambi kwesikhathi kudlala indima ebaluleke kakhulu ekusebenzeni kwe-coating.Phakathi kwezici eziningi ezithinta ukusebenza kwe-coating, ukunakekelwa kwangaphambi kobuso yiyona ebaluleke kakhulu.

Ukwelashwa kwangaphambili komhlaba kuwumsebenzi oyisisekelo

Ukwelashwa kwangaphambili kwendawo kungakha izimo zokumboza ngokusebenza okuhle kakhulu ezicini ezimbili: ngomshini, kunikeza ukuhwalala kwendawo yokumboza;Futhi kumakhemikhali, kwenza ama-molecule e-coating asondelene nobuso be-substrate yensimbi.

Nqoba umphumela omubi wendawo ebusheleleziokweenamathela

Uma ubuso bubushelelezi, ngeke kube khona ukunamathela okuhle phakathi kokugqoka nokungaphezulu, futhi ukumboza okungaphezulu kungasuswa kalula.Ngokuphambene nalokho, uma ubuso be-workpiece bunzima njenge-sandpaper, akulula ukususa ukugqoka.

Ngemuva kokwelashwa kokupeniwa (ukuqhunyiswa kwesihlabathi), indawo yensimbi izoba mahhadlahhadla njengephepha lesandpaper, okuyilokho esivame ukukubiza ngokuthi ukuhwaqeka kwendawo.

Izinto eziyingozi ezingabonakali ngeso lenyama

Ngesikhathi sokwelashwa okungaphezulu kwesakhiwo sensimbi egqwalile ngaphambi kokupenda, izingxenye ezibonisa imigodi yokugqwala ngemva kokuqhuma kokudubula (ikakhulukazi phansi kwemigodi yokugqwala) zingaqukatha usawoti oncibilikayo.Ukudubula okomile akukwazi ukususa lawa masawoti.Ngakho-ke, ngaphambi kokudweba, kungcono ukuhlola ukuthi akhona yini ama-salts ancibilikayo kanye nokugxila kwawo endaweni yokusebenza ngethuluzi lokuhlola insimu ekhethekile.Uma ukugcwala kukasawoti oncibilikayo kudlula inani elivumelekile, kufanele kuthathwe izinyathelo zokuwasusa.

Ibanga lokuhlanza

Umnotho uyinkinga okufanele siyicabangele lapho sinquma izinga lokuhlanza indawo.Ngokuvamile, lapho ziphakeme izidingo zokuhlanzeka, izindleko zokuhlanza ziphezulu.Ukuhlanza indawo yensimbi, izidingo zokuhlanzeka kwezinga eliphezulu kakhulu lokuhlanza (SA 3) zibiza kakhulu kunalezo zezinga lokungahlanzeki ngokuphelele (SA 2).Ukuhlanzwa kwendawo yezakhiwo zensimbi ezisetshenziswa endaweni egqwala kakhulu kudinga ukufinyelela izinga eliphezulu, kodwa kwezinye izikhathi, ukuphumelela kwezindleko zokuphila kwesevisi yokumboza nakho kuyisici esibalulekile ekukhethweni kwezinga lokuhlanza.

I-workpiece ephathwa nge-abrasive non-metallic abrasive ayinayo insalela ye-athomu ye-Fe futhi akulula ukugqwala nokushintsha umbala, kodwa inezinga eliphezulu lokuchotshozwa, uthuli olukhulu nokungcola okukhulu, okungahlangabezani nezidingo zokuvikelwa kwemvelo.I-TAAinsimbi engagqwali zingaxazulula kahle izinkinga okuhlangatshezwane nazo.Emkhakheni othize wokuhlanza, i-workpiece ayidingeki nje kuphela ukuthi ingabi nokugqwala kanye nokuguqulwa kombala ngemva kokwelashwa kwendawo, kodwa futhi ukwakha ukuqina okuthile ebusweni futhi kuzuzwe ukunamathela okwanele ngemva kokumboza.

Iinsimbiinhlanzieyenziwehigh carbon steel shotingahlangabezana nezidingo ezinzima ngemva kokuhlanza, kodwa ama-athomu e-Fe azohlala engaphezulu, okuholela ekugqwaleni nasekushintsheni kombala futhi kuthinte ikhwalithi yokumboza.

Insimbi engagqwali cut wireingavimbela i-workpiece ebusweni ukuthi ingagqwala futhi ishintshe umbala, kodwa iyoba yindilinga ngesikhathi sokuqhunyiswa, ngakho ayikwazi ukuhlangabezana nezidingo zokuqina.

Insimbi engagqwali iyinhlayiya yensimbi engenasici, ayikwazi nje ukuxazulula inkinga yokugqwala nokushintsha umbala ngenxa yama-athomu e-Fe asele, kodwa futhi yenza imiphetho namakhona ukuze enze ukujula kwehange okudingekayo, ithuthukise ikhwalithi yokugqoka futhi ihlangabezane nezidingo zokugqoka.Inethuba elibanzi lemakethe.

Ngaphezu kwalokho, insimbi engagqwaliinhlanziingakwazi esikhundleni senhlobonhlobo yesihlabathi samaminerali kanye nama-abrasives angewona ezensimbi, njenge-alumina oxide, i-emery, isihlabathi se-quartz, ubuhlalu bengilazi, njll.

Uma kuqhathaniswa nama-abrasives angewona ezensimbi,insimbi engagqwaliinhlanzi kungaletha izindleko eziphansi zokusebenza, ukunciphisa kakhulu ukukhishwa kwezintuli, ukunciphisa izindleko zokususa uthuli futhi kuthuthukise indawo yokusebenza.

Ukusetshenziswa kwegrit yensimbi engagqwali:
