Sobanukirwa inzira yimashini iturika kumucanga ubwenge bworoshye gukora （Ⅲ）

Shimangira ubutabazi no gukomera hejuru

Mugukubita hejuru yumurimo wumusenyi urasa, guhangayika birakurwaho kandi imbaraga zubuso bwakazi zikiyongera, nko kuvura hejuru yakazi nkibisoko, ibikoresho byo gutunganya hamwe nicyuma cyindege.

Urwego rwo gusukura imashini

Hariho amahame abiri ahagarariye mpuzamahanga agenga isuku: imwe ni “SSPC-” yashyizweho na Amerika muri 1985;Iya kabiri ni “Sa-” yateguwe na Suwede muri 76, igabanijwemo ibyiciro bine, aribyo Sa1, Sa2, Sa2.5 na Sa3, kandi ni amahame rusange mpuzamahanga.Ibisobanuro ni ibi bikurikira:

Sa1 - bihwanye na SSPC yo muri Amerika - SP7.Ukoresheje uburyo bworoshye bwo gukaraba intoki, uburyo bwo gusya imyenda ya emery, ubu ni ubwoko bune bwisuku buri hasi kuburyo bugereranije, kurinda igifuniko ni byiza cyane kurenza igihangano kidatunganijwe.Igipimo cya tekiniki yo kuvura urwego rwa Sa1: ubuso bwakazi ntigomba kuba amavuta agaragara, amavuta, okiside isigaye, ingese, irangi risigaye nandi mwanda.Sa1 nayo yitwa Manual brush.(cyangwa isuku y'ishuri)

Urwego rwa Sa2 - bihwanye na Amerika SSPC - urwego rwa SP6.Gukoresha uburyo bwo gusukura umucanga, aribwo buryo bwo hasi bwo kuvura umucanga, ni ukuvuga ibisabwa muri rusange, ariko kurinda igifuniko kuruta gusukura intoki zogejwe kugirango bitezimbere benshi.Igipimo cya tekiniki yo kuvura Sa2: ubuso bwakazi bugomba kuba butarimo amavuta, umwanda, oxyde, ingese, irangi, okiside, ruswa, nibindi bintu byamahanga (usibye inenge), ariko inenge ntishobora kurenga 33% yubuso kuri kare metero, harimo igicucu gito;Umubare muto w'amabara make uterwa n'inenge cyangwa ingese;Oxide uruhu no gusiga irangi.Niba hari akavuyo hejuru yumwimerere wakazi, ingese nkeya hamwe n irangi bizaguma munsi yurwobo.Icyiciro cya Sa2 nanone cyitwa icyiciro cyo gusukura ibicuruzwa (cyangwa urwego rwinganda).

Sa2.5 - uru ni urwego rusanzwe rukoreshwa mu nganda kandi rushobora kwemerwa nkibisabwa tekiniki kandi bisanzwe.Sa2.5 nayo yitwa hafi yisuku yera (hafi yumweru cyangwa yera).Sa2.5 igipimo cya tekiniki: kimwe nigice cyambere cya Sa2, ariko inenge igarukira kurenza 5% yubuso kuri metero kare, harimo igicucu gito;Umubare muto w'amabara make uterwa n'inenge cyangwa ingese;Oxide uruhu no gusiga irangi.

Icyiciro Sa3 - Bingana na SSPC yo muri Amerika - SP5, nicyiciro cyo hejuru cyo kuvura mu nganda, kizwi kandi nk'icyiciro cyo kweza cyera (cyangwa icyiciro cyera).Urwego rwa Sa3 gutunganya tekinike yubuhanga: kimwe nurwego rwa Sa2.5, ariko igicucu cya 5%, inenge, ingese nibindi bigomba kubaho.
