Qonda inkqubo yomatshini wokuqhumisa isanti, indlela esebenza ngayo ngokulula (Ⅲ)

Ukunciphisa uxinzelelo kunye nokuqinisa umphezulu

Ngokubetha umphezulu wesixhobo sokusebenza ngesanti, uxinzelelo luyasuswa kwaye amandla omphezulu wesixhobo sokusebenza ayandiswa, njengonyango lomphezulu wesixhobo sokusebenza esifana nezipringi, izixhobo zoomatshini kunye neebhleyidi zeenqwelo-moya.

Umgangatho wokucoca umatshini wokuqhumisa isanti

Kukho imigangatho emibini emeleyo yamazwe ngamazwe yococeko: omnye yi-"SSPC-" eyasekwa yi-United States ngo-1985; owesibini yi-"Sa-" eyenziwe yiSweden kwi-76, eyahlulwe yangamanqanaba amane, okuyi-Sa1, i-Sa2, i-Sa2.5 kunye ne-Sa3, kwaye ngumgangatho oqhelekileyo wamazwe ngamazwe. Iinkcukacha zezi zilandelayo:

I-Sa1 – ilingana ne-US SSPC – SP7. Ukusebenzisa ibrashi elula yesandla, indlela yokugaya ilaphu le-emery, olu hlobo lune lococeko luphantsi kakhulu, ukhuseleko lwengubo lungcono kancinci kune-workpiece ngaphandle kokucutshungulwa. Umgangatho wobuchwephesha wonyango lwenqanaba le-Sa1: umphezulu we-workpiece akufuneki ubonakale ioyile, igrisi, i-residual oxide, umhlwa, ipeyinti eseleyo kunye nolunye uthuli. I-Sa1 ikwabizwa ngokuba yi-Manual brush cleaning. (okanye iklasi yokucoca)

Inqanaba le-Sa2 — elilingana nele-US SSPC — inqanaba le-SP6. Ukusetyenziswa kwendlela yokucoca ngesanti, eyona iphantsi kunyango lwesanti, oko kukuthi, iimfuno eziqhelekileyo, kodwa ukhuseleko lwengubo kunokucoca ngebrashi ngesandla ukuphucula uninzi. Umgangatho wobuchwephesha wonyango lwe-Sa2: umphezulu we-workpiece mawungabi namafutha, ukungcola, i-oxide, umhlwa, ipeyinti, i-oxide, umhlwa, kunye nezinye izinto zangaphandle (ngaphandle kweziphene), kodwa iziphene aziyi kudlula i-33% yomphezulu ngemitha yesikwere, kubandakanya izithunzi ezincinci; Ubungakanani obuncinci bokutshintsha kombala okubangelwa ziziphene okanye umhlwa; Iziphene zolusu lwe-Oxide kunye nepeyinti. Ukuba kukho ukubola kumphezulu wokuqala we-workpiece, umhlwa omncinci kunye nepeyinti ziya kuhlala ezantsi kwe-dent. Inqanaba le-Sa2 likwabizwa ngokuba yi-commodity cleaning grade (okanye i-industrial grade).

I-Sa2.5 – le yinqanaba elisetyenziswa rhoqo kushishino kwaye linokwamkelwa njengemfuneko yobugcisa kunye nomgangatho. I-Sa2.5 ikwabizwa ngokuba yi-close White cleanup (kufuphi nomhlophe okanye ngaphandle komhlophe). Umgangatho wobugcisa we-Sa2.5: ufana nenxalenye yokuqala ye-Sa2, kodwa isiphene silinganiselwe kwi-5% yomphezulu ngemitha yesikwere, kubandakanya umthunzi omncinci; Ubungakanani obuncinci bokutshintsha kombala okubangelwa ziziphene okanye umhlwa; Iziphene zolusu kunye nepeyinti ze-Oxide.

Iklasi ye-Sa3 — Elingana ne-US SSPC — SP5, lolona hlobo lonyango luphezulu kushishino, olukwaziwa ngokuba yi-White Cleaning Class (okanye iklasi emhlophe). Umgangatho wobuchwephesha wokucubungula umgangatho we-Sa3: ufana nomgangatho we-Sa2.5, kodwa kufuneka kubekho isithunzi se-5%, iziphene, umhlwa, njalo njalo.
