Sobanukirwa inzira ikoreshwa mu gutwika umucanga, uburyo bworoshye bwo gukora (Ⅲ)

Kugabanya stress no gukomeza ubuso

Gukubita hejuru y'icyuma gikoreshwa n'umucanga, stress irakurwaho kandi imbaraga z'icyuma gikoreshwa zikongera, nko gutunganya ubuso bw'icyuma gikoreshwa nk'amasoko, ibikoresho byo gukora imashini n'ibyuma by'indege.

Imashini zisukura umucanga mu rwego rwo gusukura

Hari amahame abiri mpuzamahanga ahagarariye isuku: rimwe ni "SSPC-" ryashyizweho na Leta Zunze Ubumwe za Amerika mu 1985; Irya kabiri ni "Sa-" ryakozwe na Suwede muri 76, rigabanyijemo ibyiciro bine, ari byo Sa1, Sa2, Sa2.5 na Sa3, kandi ni ryo tegeko mpuzamahanga risanzwe. Ibisobanuro birambuye ni ibi bikurikira:

Sa1 – ingana na THE US SSPC – SP7. Hakoreshejwe uburoso bworoshye bwo gukoresha intoki, uburyo bwo gusya imyenda ya emery, ubu ni ubwoko bune bw'isuku buri hasi cyane, uburinzi bw'igitambaro ni bwiza gato kuruta igikoresho cyo gukoraho hatabayeho gutunganya. Ibipimo ngenderwaho bya tekiniki byo gutunganya Sa1 ku rwego rw'urwego: hejuru y'igikoresho cyo gukoraho ntihagomba kugaragara amavuta, amavuta, okiside isigaye, ingese, irangi risigaye n'indi myanda. Sa1 yitwa kandi isuku y'uburoso ikoresheje intoki. (cyangwa icyiciro cyo gusukura)

Urwego rwa Sa2 — rungana na THE US SSPC — urwego rwa SP6. Gukoresha uburyo bwo gusukura umucanga, ari nabwo buri hasi mu gutunganya umucanga, ni ukuvuga ibisabwa rusange, ariko kurinda irangi kuruta gusukura uburoso n'intoki kugira ngo birusheho kunoza byinshi. Igipimo ngenderwaho cya tekiniki cyo gutunganya Sa2: ubuso bw'aho gukorera bugomba kuba budafite amavuta, umwanda, okiside, ingese, irangi, okiside, ingese, n'ibindi bintu by'amahanga (usibye inenge), ariko inenge ntizigomba kurenza 33% by'ubuso kuri metero kare, harimo n'igicucu gito; Ibara rito ry'ibara riterwa n'inenge cyangwa ingese; Inenge z'uruhu n'irangi bya okiside. Niba hari ipfundo ku buso bw'umwimerere bw'aho gukorera, ingese nke n'irangi bizaguma hasi ku ipfundo. Urwego rwa Sa2 runatwa urwego rwo gusukura ibicuruzwa (cyangwa urwego rw'inganda).

Sa2.5 – uru ni rwo rwego rukunze gukoreshwa mu nganda kandi rushobora kwemerwa nk'ibisabwa mu rwego rwa tekiniki n'ibipimo ngenderwaho. Sa2.5 yitwa kandi isukura ryera hafi y'umweru (hafi y'umweru cyangwa hanze y'umweru). Ibipimo ngenderwaho bya tekiniki bya Sa2.5: kimwe n'igice cya mbere cya Sa2, ariko inenge igarukira ku kigero kitarenze 5% by'ubuso kuri metero kare, harimo n'igicucu gito; Ihinduka rito ry'ibara riterwa n'inenge cyangwa ingese; Inenge z'uruhu n'irangi bya okiside.

Icyiciro cya Sa3 — Kingana na SSPC yo muri Amerika — SP5, ni cyo cyiciro cyo kuvura kiri hejuru mu nganda, kizwi kandi nka white Cleaning Class (cyangwa white class). Igipimo cya tekiniki cyo gutunganya ku rwego rwa Sa3: kimwe n'urwego rwa Sa2.5, ariko 5% by'igicucu, inenge, ingese n'ibindi bigomba kubaho.
