Qonda inqubo yokusebenza komshini wokuqhuma isihlabathi ngendlela enengqondo (Ⅲ)

Ukukhululeka ekucindezelekeni nasekuqiniseni ubuso

Ngokushaya ubuso bento yokusebenza ngesihlabathi, ukucindezeleka kuyasuswa futhi amandla obuso bento yokusebenza ayakhuliswa, njengokwelashwa kobuso bento yokusebenza njengeziphethu, amathuluzi omshini kanye nama-blade endiza.

Ibanga lokuhlanza umshini wokuqhumisa isihlabathi

Kunezindinganiso ezimbili zomhlaba wonke ezimele inhlanzeko: eyodwa yi-“SSPC-” eyasungulwa yi-United States ngo-1985; eyesibili yi-“Sa-” eyaklanywa yiSweden ngo-76, ehlukaniswe ngamabanga amane, okuyi-Sa1, i-Sa2, i-Sa2.5 kanye ne-Sa3, futhi iyindinganiso evamile yomhlaba wonke. Imininingwane imi kanje:

I-Sa1 – ilingana ne-US SSPC – SP7. Ukusebenzisa ibhulashi elijwayelekile elilula lesandla, indlela yokugaya indwangu ye-emery, lokhu kuyindlela yokuhlanzeka enezinhlobo ezine, ukuvikelwa kwesembozo kungcono kancane kunesento yokusebenza ngaphandle kokucutshungulwa. Izinga lobuchwepheshe lokwelashwa kwezinga le-Sa1: ubuso bento yokusebenza akufanele bubonakale uwoyela, amafutha, i-residual oxide, ukugqwala, upende osele kanye nokunye ukungcola. I-Sa1 ibizwa nangokuthi ukuhlanza ibhulashi ngesandla. (noma ikilasi lokuhlanza)

Izinga le-Sa2 — elilingana nele-US SSPC — izinga le-SP6. Ukusetshenziswa kwendlela yokuhlanza i-sandblasting, okuyiyona ephansi ekwelashweni kwe-sandblasting, okungukuthi, izidingo ezijwayelekile, kodwa ukuvikelwa kwengubo kunokuhlanza ibhulashi ngesandla ukuthuthukisa eziningi. Izinga lobuchwepheshe lokwelashwa kwe-Sa2: ubuso be-workpiece kumele bungabi nama-grease, ukungcola, i-oxide, ukugqwala, upende, i-oxide, ukugqwala, nezinye izinto zakwamanye amazwe (ngaphandle kwamaphutha), kodwa amaphutha akufanele adlule u-33% wobuso ngemitha yesikwele, kufaka phakathi izithunzi ezincane; Inani elincane lokushintsha kombala okubangelwa amaphutha noma ukugqwala; Amaphutha esikhumba se-Oxide kanye nopende. Uma kukhona ukugoba ebusweni bokuqala be-workpiece, ukugqwala okuncane kanye nopende kuzohlala phansi kwe-dent. Izinga le-Sa2 libizwa nangokuthi izinga lokuhlanza impahla (noma izinga lezimboni).

I-Sa2.5 – leli yizinga elivame ukusetshenziswa embonini futhi lingamukelwa njengemfuneko yobuchwepheshe kanye nezinga elijwayelekile. I-Sa2.5 ibizwa nangokuthi i-Near White cleanup (eduze kwemhlophe noma ngaphandle kwemhlophe). Izinga lobuchwepheshe le-Sa2.5: lifana nengxenye yokuqala ye-Sa2, kodwa iphutha lilinganiselwe ku-5% wobuso ngemitha yesikwele, kufaka phakathi isithunzi esincane; Inani elincane lokushintsha kombala okubangelwa amaphutha noma ukugqwala; Amaphutha esikhumba nepende ane-oxide.

I-Class Sa3 — Efana ne-US SSPC — SP5, iyisigaba sokwelashwa esiphezulu embonini, esaziwa nangokuthi i-White Cleaning Class (noma i-white class). I-Sa3 level processing technical standard: iyafana ne-Sa2.5 level, kodwa isithunzi esingu-5%, amaphutha, ukugqwala nokunye kufanele kube khona.
