Kurangiza ubuso

Ubuso bw'icyuma cy'umukara
Irangi ry’icyuma cy’umukara risanzwe ni amahitamo afatika kandi ahendutse mu bwubatsi rusange bw’imbere mu gihugu. Rikora neza cyane ku mishinga y’ubwubatsi isaba gukata, gusudira, cyangwa ubundi buryo bwo gukora ku nyubako, ritanga uburyo bworoshye bwo gukora imirimo isanzwe y’urufatiro.

Igipfundikizo cya Fusion Bonded Epoxy (FBE)
Irangi rya FBE rikora nk'iry'uburinzi bukomeye bw'urwego rumwe. Ritanga ubudahangarwa bukomeye ku isuri n'ubushyuhe bw'ubuso, ritanga uburinzi bwizewe kandi burambye ku nyubako z'ibyuma zo munsi y'ubutaka n'izo mu nganda.

Sisitemu yo gusigaho 3PE
Igitambaro cy’ingenzi cya 3PE gifite ibara ry’inyongera ni igisubizo gikomeye cyo kurinda cyubatswe n’ibara ry’inyongera rigizwe n’ibara ritatu rikora neza, harimo ishingiro rya epoxy primer, ibara ry’ubudodo, n’uburinzi bukomeye bwa polyethylene. Iyi nyubako ifite ibara ry’inyongera yongera cyane kuramba muri rusange no kwihuza n’ibidukikije, bigatuma iba amahitamo meza yo gukora imirimo yo mu mazi yo ku nkombe z’inyanja, inyubako zo mu nyanja, n’imishinga y’imiyoboro ishyinguye.

Sisitemu zo Kurinda Zikozwe mu Buryo Bwite
Dutanga ibisubizo byuzuye byo gusiga kugira ngo bihuze n'imiterere yihariye y'umushinga. Uburyo bwose bwo kurinda ubuso bushobora guhindurwa hashingiwe ku bipimo nyabyo by'aho hantu, harimo imiterere y'ubutaka bwo mu gace runaka, urwego rw'umunyu n'amazi, igihe serivisi zigenewe, ndetse n'imiterere y'umushinga ku giti cyawo n'ibisabwa mu bya tekiniki.

Porogaramu nyamukuru

1. Ishingiro ry'inkuta zo munsi y'ubutaka:Kubaka munsi y'ubutaka ku nyubako ndende, inganda, ububiko, amazu y'ubucuruzi n'ay'abaturage. Ishingiro ry'ibirundo (ubwoko bwose bw'inyubako).

2. Ishingiro ry'ibirundo by'ibiraro:Ishingiro ry'ibiraro by'imihanda minini, ibiraro bya gari ya moshi, n'inzira z'umujyi. Ishingiro ry'ibiraro by'imigezi, ibiyaga n'inyanja.

3. Kubaka icyambu:Ifatizo ritwara imizigo ku byambu, aho amato akorera n'aho indege zihagarara. Serivisi zo gutanga ibikoresho biremereye n'imizigo ku byambu.

4. Imishinga y'Ingufu z'Umuyaga n'Ubwubatsi bw'Amato mu Nyanja:Ishingiro ry'ibyuma bikoresha umuyaga byo mu nyanja. Igishushanyo mbonera cy'inyubako zo mu nyanja, imiyoboro yo mu nyanja, imiyoboro yo mu nyanja, inkuta z'inyanja n'ahandi. Mu mazu yo guturamo, kurwanya amazi, kurwanya imiraba, no kwangirika kw'amazi yo mu nyanja.

5. Ubwubatsi Bunini bw'Ibwubatsi:Imisingi ikomeye ifite imiringoti y'umurambararo mugari yo gukora imirimo minini y'ubwubatsi (ingomero, sitasiyo za gari ya moshi, n'imiyoboro y'amazi). Inkunga ku mashini n'imitwaro y'inganda.

Gupakira no Gutanga

1 Paki:Imigozi y'icyuma yoroshye kuyifata. Ibiti cyangwa uduce tw'ibiti bishyirwa hagati y'ibirundo kugira ngo hirindwe ko ingingo zihinduka mu gihe cyo kohereza. Gutunganya ubuso (ni ngombwa): Gusiga irangi ry'umukara, amavuta yo gukumira ingese, firime ya pulasitiki. Ibirundo bya galvanizi bishobora kandi gupfunyikwa muri firime ya pulasitiki y'agateganyo kugira ngo hirindwe ko hejuru hagwa. Hari ipaki yihariye.

2 Amakuru yerekeye ibyo umuntu yaguze:Uburebure busanzwe buri mu bubiko: metero 6, metero 12. Uburebure: busanzwe kandi bwihariye. Biza hamwe na gari ya moshi yo mu mazi n'uburyo bwo kuyikoresha. Bikwiriye gutwara abantu mu mazi, gari ya moshi cyangwa mu muhanda, kandi birakomeye bihagije mu gihe cyo kuyikoresha mu muhanda. Igihe cyo kuyitanga ni iminsi 15-30 nyuma yo kwakira amafaranga, bitewe n'ingano n'ibisobanuro. Bikoreshwa mu kohereza ibicuruzwa ku isi yose, hamwe n'inyandiko yuzuye (Impamyabushobozi y'ikizamini, Urutonde rw'ibipakiye, Inyandiko y'ibicuruzwa).

3 Ingamba zo kwirinda:Ntugakoreshe imigozi cyangwa udukingirizo tudafite udukingirizo kugira ngo uhure n'umuyoboro w'amazi, ibyo bikaba byatera kwangirika kw'imiyoboro. Bika ahantu hakonje, humutse kandi hari umwuka mwiza. Kugira ngo wirinde ingese mbere yo kuyishyiraho. Imizigo minini kandi iremereye igomba kubahiriza amabwiriza yo kohereza ibicuruzwa mu gace utuyemo.
