Bishyushye bishyushye I-beam
Ibisobanuro bigufi:
Amashanyarazi ashyushye I-beam nayo yitwa hot-dip galvanised I-beam cyangwa hot-dip galvanised I-beam.Nukwibiza I-beam yashutswe muri zinc yashongeshejwe hafi 500 ℃, kugirango igipande cya zinc gifatanye hejuru ya I-beam, kugirango tugere ku ntego yo kurwanya ruswa.Birakwiriye kubwoko bwose bwibidukikije byangirika nka acide ikomeye hamwe nigihu cya alkali.
Ibyiza byibicuruzwa
1. Igiciro gito cyo kuvura: ikiguzi cyo gushyushya-guswera no kwirinda ingese ni munsi ugereranije nandi marangi;
2. Kuramba: ibyuma bishyushye bishyushye bifite ibyuma biranga uburinganire bwubuso, igipande kimwe cya zinc, nta plaque yabuze, nta gutonyanga, gukomera hamwe no kurwanya ruswa.Mubidukikije byumujyi, ubushyuhe busanzwe bwa dip-galvanised antirust irashobora kubungabungwa mumyaka irenga 50 itabanje gusanwa;Mu bice byo mumijyi cyangwa hanze yinyanja, ibishyushye bishyushye bya antirust birashobora gukomeza kumara imyaka 20 bidasanwa;
3. Kwizerwa kwiza: gutwika zinc hamwe nicyuma byahujwe mubyuma kandi bigahinduka igice cyicyuma, bityo rero igihe cyo gutwikira kirashobora kwizerwa;
4. Gukomera gukomeye: gutwika zinc bigize imiterere yihariye ya metallurgjique, ishobora kwihanganira ibyangiritse mugihe cyo gutwara no gukoresha;
5. Kurinda byimazeyo: buri gice cyibice byashizwemo birashobora gushyirwaho zinc, kandi birashobora gukingirwa byimazeyo no mubihebye, inguni zikarishye nahantu hihishe;
6. Kuzigama umwanya no kuzigama umurimo: inzira ya galvanisiyasi irihuta kuruta ubundi buryo bwo kubaka, kandi igihe gisabwa cyo gushushanya kurubuga nyuma yo kwishyiriraho kirashobora kwirindwa.
