Qonda inqubo yomshini wokuqhumisa isihlabathi ukusebenza okulula komqondo ojwayelekile (Ⅲ)

Ukunciphisa ingcindezi nokuqinisa indawo

Ngokushaya ingaphezulu le-workpiece nge-sand shot, ukucindezeleka kuyaqedwa futhi amandla angaphezulu e-workpiece ayanda, njengokwelashwa okungaphezulu kwendawo yokusebenza njengeziphethu, amathuluzi omshini nama-blade endiza.

Ibanga lokuhlanza umshini wokuqhunyiswa kwesihlabathi

Kunamazinga amabili amele amazwe ngamazwe okuhlanzeka: enye yi-“SSPC-” eyasungulwa yi-United States ngo-1985; Eyesibili i-“Sa-” eyakhiwe yiSweden ngo-76, ehlukaniswe ngamabanga amane, okuyi-Sa1, i-Sa2, i-Sa2.5 ne-Sa3, futhi iyindinganiso evamile yamazwe ngamazwe. Imininingwane imi kanje:

I-Sa1 – ilingana ne-US SSPC – SP7. Ukusebenzisa ibhulashi elivamile elilula le-manual, indlela yokugaya indwangu ye-emery, lezi izinhlobo ezine zokuhlanzeka ziphansi ngokusesilinganisweni, ukuvikelwa kwe-coating kungcono kancane kune-workpiece ngaphandle kokucubungula. Izinga lobuchwepheshe lokwelashwa kwezinga le-Sa1: ubuso bomsebenzi akufanele bubonakale amafutha, amafutha, i-oxide esele, ukugqwala, upende osele nokunye ukungcola. I-Sa1 ibizwa nangokuthi i-Manual brush cleaning. (noma ikilasi lokuhlanza)

Ileveli ye-Sa2 — ilingana ne-US SSPC — ileveli ye-SP6. Ukusetshenziswa kwendlela yokuhlanza i-sandblasting, okuyiyona ephansi ekwelapheni kwe-sandblasting, okungukuthi, izidingo ezijwayelekile, kodwa ukuvikelwa kokugqoka kunokuhlanza ibhulashi le-manual ukuthuthukisa eziningi. Izinga lobuchwepheshe lokwelashwa kwe-Sa2: indawo yokusebenza ngeke ingabi namafutha, ukungcola, i-oxide, ukugqwala, upende, i-oxide, ukugqwala, nezinye izinto zangaphandle (ngaphandle kwamaphutha), kepha amaphutha angeqi ku-33% wobuso ngesikwele ngasinye. imitha, kuhlanganise nezithunzi ezincane; Inani elincane lokushintsha kombala okuncane okubangelwa ukukhubazeka noma ukugqwala; Isikhumba se-oksidi nokulimala kopende. Uma kukhona ukubola endaweni yokuqala yomsebenzi, ukugqwala okuncane nopende kuzohlala ngaphansi kwesibotho. Ibanga le-Sa2 libizwa nangokuthi ibanga lokuhlanza impahla (noma ibanga lezimboni).

I-Sa2.5 - leli izinga elivame ukusetshenziswa embonini futhi lingamukelwa njengemfuneko yobuchwepheshe kanye nezinga. I-Sa2.5 ibizwa nangokuthi eduze kokuhlanza okumhlophe (eduze okumhlophe noma okumhlophe). I-Sa2.5 standard yobuchwepheshe: iyafana nengxenye yokuqala ye-Sa2, kodwa isici sinqunyelwe hhayi ngaphezu kuka-5% wendawo ngayinye imitha yesikwele, kuhlanganise nomthunzi omncane; Inani elincane lokushintsha kombala okuncane okubangelwa ukukhubazeka noma ukugqwala; Isikhumba se-oksidi nokulimala kopende.

I-Class Sa3 — Ilingana ne-US SSPC — SP5, isigaba sokwelapha esiphezulu embonini, esaziwa nangokuthi Ikilasi Lokuhlanza Elimhlophe (noma isigaba esimhlophe). Izinga le-Sa3 lokucubungula izinga lobuchwepheshe: okufana nezinga le-Sa2.5, kodwa ithunzi elingu-5%, amaphutha, ukugqwala nokunye kufanele kube khona.
