EN 10248 Z Ubwoko bw'icyuma gikingira ingese

Amerika: HDG (dukurikije ASTM A123, ubunini bwa zinc ≥ 85μm) + irangi rya 3PE rishobora gupimwa, ryanditseho "Ryubahiriza RoHS mu buryo burengera ibidukikije".

Aziya y'Amajyepfo y'Uburasirazuba: Ikoresheje uburyo buhuriweho bwo gushyiramo gazi ishyushye (ubugari bwa zinc layer ≥ 100μm) hamwe no gusiga epoxy coal tar, inyungu yayo nyamukuru ni uko itagira ingese ndetse na nyuma y'amasaha 5.000 yo gupima umunyu, bigatuma ikwiriye ibidukikije byo mu nyanja bishyuha.

EN 10248 Z Ubwoko bwa Z Ifunga ry'Impapuro z'Icyuma

Igishushanyo: Ifunze ifite ishusho ya Z, ubushobozi bwo kwinjira ≤1×10⁻⁷cm/s
Amerika: Yujuje ibisabwa na ASTM D5887, uburyo busanzwe bwo gupima amazi yinjira mu nkuta z’ibanze n’izifata amazi.
Aziya y'Amajyepfo y'Uburasirazuba: Amazi yo mu butaka menshi kandi arwanya imyuzure mu turere dushyuha n'utwo mu gihe cy'imvura nyinshi

Uburyo bwo gukora icyuma gikozwe mu mpapuro z'icyuma zo mu bwoko bwa ASTM Z

Amahitamo y'ibyuma:

Hitamo icyuma cy'ubwubatsi cyiza cyane ukurikije ibisabwa ku miterere ya mekanike.

Gushyushya:

Shyushya ibipande/amasahani kugeza kuri ~1,200°C kugira ngo bihinduke neza.

Gushyuha cyane:

Kora icyuma muri Z-profile ukoresheje inganda zizunguruka.

Gukonjesha:

Konjesha kuri Cool cyangwa ushyire amazi yo mu ipombo kugeza igihe amazi yagenewe agereranyijwe.

Kugorora no Gukata:

Komeza gukoresha neza ubushobozi bwo gupima ibintu mu gihe ukata ibikoresho ku burebure busanzwe cyangwa busanzwe.

Igenzura ry'Ubuziranenge:

Kora igenzura ry'ibipimo, imashini n'amaso.

Uburyo bwo kuvura ubuso (Uburyo bwo guhitamo):

Niba bikenewe, shyira irangi, shyiramo galvanize cyangwa urinde ingese.

Gupakira no Kohereza:

Pakira, rinda, kandi ufate kugira ngo wohereze.

Inkuta zirinda ibidukikije– Itanga ubufasha bwizewe ku butaka mu gutunganya no gukoresha ishingiro.

Cofferdams– Inkuta zirinda amazi zituma amazi atembera neza mu bice by'ubwubatsi.

Imishinga yo ku cyambu n'icyambu– Ikwiriye inkuta z'aho ubwato buherereye, ibyambu n'ibindi bikorwa byo mu mazi.

Kugenzura imyuzure no Guhagarara kw'inkombe z'amazi– Ikomeza inkombe n'imiyoboro y'amazi hakoreshejwe fibre, kandi ikarwanya isuri.

Gupakira no Kohereza

Ibipfunyika bisanzwe byo kohereza mu mahanga– Bifatanye n'imigozi y'icyuma kandi bikomejwe n'insinga z'icyuma.

Uburinzi bukwiriye amazi yo mu nyanja– Bipfunyitse mu bikoresho bidapfa amazi kugira ngo birinde ingese mu gihe cyo kuyinyuramo.

Uburyo bwo Gupakira– Gushyiramo ibintu byinshi cyangwa kontineri (20GP / 40GP).

Uburyo bwo gucunga neza- Gushyira hamwe neza kugira ngo hirindwe kwangirika.

Uburyo bworoshye bwo gutanga– FOB, CFR, CIF zirahari.

Kohereza vuba– Gutanga ibicuruzwa mu minsi 7–15 kugira ngo ubone ibyo watumije mu bubiko.

Ibibazo Bikunze Kubazwa

Q1: Igiciro ni kingana iki?
A: Igiciro giterwa n'urwego, ingano, n'ingano. Twandikire kugira ngo ubone ibiciro bishimishije.

Q2: Ni angahe ingano ntoya y'itumiza (MOQ)?
A: Ingano ntoya (MOQ) itangirana na toni 25 ku ngano z'ibicuruzwa; ingano zihariye zishobora gutandukana.

Q3: Ni ibihe biteganyijwe mu kwishyura byemewe?
A: T/T cyangwa ubundi buryo bwemewe.

Q4: Ni gute ubuziranenge bwizewe?
A: MTC yatanzwe; igenzura rikomeye ry’imbere mu kigo; igenzura ry’abantu ba gatatu rirahari.

Q5: Ni iyihe nkunga mutanga nyuma yo kugurisha?
A: Ubuyobozi bwa tekiniki, gusimbuza ibibazo by’ubuziranenge, n’ubufasha bwo gusubiza ibibazo.
