Igishushanyo: Ikirundo cy'icyuma gihuza, ubushobozi bwo kwinjira ≤1×10⁻⁷ cm/s
Amerika: Yujuje ibipimo bya ASTM D5887 kugira ngo agakoresho ko mu mazi gagabanuke munsi y'ingoma
Aziya y'Amajyepfo y'Uburasirazuba: Amazi yo hasi ashobora kunyura mu bihe by'imvura yo mu turere dushyuha
Uburyo bwo gukora EN 10248 Hot Rolled S270GP S320GP S355GP S390GP S430GP Steel Sheet Pitch
1. Guhitamo ibikoresho fatizo
Ibikoresho by'icyuma cyangwa ibyuma bitoranywa neza kugira ngo imiterere yabyo n'imiterere yabyo bikomeze kugumana ubuziranenge.
2. Gushyushya mu itanura
Icyuma gishyushya ubushyuhe buri hejuru y'ubushyuhe bwacyo bwo kongera gushyuha kugira ngo gishobore gushyuha neza.
3. Gushyuha cyane
Icyuma kandi gikorwa mu buryo bwa U-type na Z-type, bikoreshwa mu gukora imiterere ikomeye, imigozi n'imigozi ifatanye, bikoreshwa mu gukora imigozi y'imigozi ifunganye.
4. Gukonjesha no Kugorora
Gukonjesha bigenzurwa bizana icyuma gihamye kandi kugorora byongera ingano nyayo n'ubuso bworoshye.
5. Kuvura ubuso
Ibirundo by'amabati bishobora gutangwa mu buryo bwa "finish" cyangwa "galvanized" kugira ngo birindwe ingese.
6. Gukata no gucukura (Ntabwo ari ngombwa)
Uburebure bwakozwe ku buryo bwihariye kandi bufite imyobo yabanje gucukurwa kugira ngo ihuze n'ibyo umushinga ukeneye.
7. Igenzura ry'Ubuziranenge n'Impamyabushobozi
Ibice byose bipimwa kugira ngo byuzuze ibisabwa mu buhanga, mu by'imashini no mu bipimo kandi bigakurikiza EN 10204 3.1 MTC.
EN 10248 Ishyushye Izungurutse S270GP S320GP S355GP S390GP S430GP Ubuso bw'urukuta rw'icyuma
Amerika:HDG nka ASTM A123 (agapira ka zinc kari munsi ya ≥ 85 µm); irangi rya 3PE ni amahitamo; irangi ryose rikurikiza RoHS.
Aziya y'Amajyepfo y'UburasirazubaUbunini bwa galvanized ishyushye ni hollyh (irenga 100μm), kandi hashyirwamo ibice bibiri bya epoxy coal tar, ishobora gusukwaho umunyu ikageragezwa amasaha 5000 nta ngese, niyo nziza cyane mu bidukikije byo mu nyanja.
UBUSABIZI
1. Icyuma cy'ubwubatsi bw'icyambu:Ikoreshwa mu kubaka ibyambu, ibyambu, n'inkuta za karike, itanga inkunga ikomeye y'inyubako no kuramba igihe kirekire mu bidukikije byo mu mazi.
2. Ikirundo cy'icyuma gikingira Riverbank:Yagenewe gutuza inkombe z'imigezi, gukumira isuri, no kurinda ingaruka z'amazi n'imyuzure.
3. Ikirundo cy'icyuma gishingiye ku kiraro:Ikoreshwa mu kubaka ibiraro kugira ngo itange inkunga y'urufatiro rwimbitse kandi ihamye mu gihe cy'imitwaro iremereye.
4. Imiterere yo munsi y'ubutaka Ikirundo cy'icyuma:Bishyirwa mu mazu yo munsi y'ubutaka, mu tunnel, no mu nyubako zo munsi y'ubutaka kugira ngo bitange uburyo bwo kubika no gucukura ubutaka mu buryo bwizewe.
Kuki wahitamo icyuma cy'ubushinwa cy'ubwami ku byuma bicukurwamo amabati
1.Iturutse mu ruganda rutanga serivisi– Shaka igiciro kidafite abahuza kandi utange vuba.
2.Ireme ryemewe– EN 10248 hamwe naEN 10248 3.1 MTCkugira ngo hamenyekane neza uko ibintu byose bigenda.
3.Ibicuruzwa binini n'amahitamo yihariye– Dufite amatoni amagana kandi dushobora gutanga ingano zihariye ku mushinga uwo ari wo wose.
4.Ubuhanga bwo kohereza ibicuruzwa mu mahanga ku isi yose- Kohereza ibicuruzwa mu majyepfo y'uburasirazuba bwa Aziya, mu Burasirazuba bwo Hagati, mu Burayi no muri Amerika buri gihe.
5.Inkunga ya tekiniki- Shaka inama z'inzobere ku bijyanye no guhitamo impapuro zigomba gutegurwa, kuzishyiraho no kuzisubiza mu mishinga.
6.Serivisi nyuma yo kugurisha– Kuva mu ntangiriro kugeza ku iherezo, twitaye ku mibereho myiza y'umushinga wawe. Serivisi yo gufasha umushinga wawe nyuma yo kugurisha ni yo twiyemeje kugufasha.
GUPIKA NO KOHEREZA
Gupfunyika neza– Ibirundo by'amabati bipfunyikwa mu mipfunyika irimo imishumi y'icyuma ikomeje gukomezwa bihagije kugira ngo ibicuruzwa bitazangirika mu nzira.
Uburinzi bw'inyongera– Uburyo bwo kurwanya ingese, gupfunyika mu pulasitiki cyangwa gupakira byihariye birahari.
Kohereza mu buryo bworoshye- Ni byiza cyane ku gutwara abantu mu mazi, gari ya moshi cyangwa mu muhanda kugira ngo bigerweho neza ku isi yose.
Gutanga byihuse– Gutanga ibicuruzwa mu buryo butaziguye mu ruganda, igihe cyo kubitanga gisanzwe ni iminsi 7-15.
Ubunararibonye ku Isi mu Kohereza mu mahanga– Twayohereje mu majyepfo y'uburasirazuba bwa Aziya, mu Burasirazuba bwo Hagati, mu Burayi no muri Amerika.
Ibibazo Bikunze Kubazwa
Q1: Ni ubuhe bwoko bw'ibirundo by'ibyuma mutanga?
A: Dushobora gutanga impapuro za S270GP, S320GP, S355GP, S390GP na S430GP zihuye n'amahame ya EN 10248.
Q2: Ese nshobora kubona uburebure n'imiterere byihariye?
A: Yego, dufite impapuro zometseho ubwoko bwa U, ubwoko bwa Z, n'izindi zifatanye mu burebure butandukanye buri hagati ya metero 6 na metero 18.
Q3: Ufite icyemezo?
A: Impapuro zacu zose zitangwa hakoreshejwe EN 10204 3.1 MTC, zitanga uburyo bwo gukurikirana no kubahiriza ibisabwa byose.
Q4: Ni ubuhe bwoko bw'ubuvuzi bwo ku buso bushobora gukorwa?
A: Ibirundo by'amabati bishobora kuba byarakozwe mu buryo bw'urusyo, byakozwe mu buryo bwa galvanised cyangwa byasizwe irangi kugira ngo birinde ingese.
Q5: Igihe cyawe cyo gutanga serivisi ni kingana iki?
A: Gutanga ibicuruzwa mu buryo butaziguye mu ruganda, bikagezwa mu minsi 7-15 bitewe n'ingano n'aho bigiye gukorerwa.
