Insimbi emise okwe-U (igama eligcwele:insimbi egoqiwe emise okwe-Ungosekelo lwami lomgwaqo)
Insimbi emise okwe-U iwuhlobo lwensimbi enesigaba esiphambanayo njengohlamvu lwesiNgisi oluthi "U", futhi ngezinye izikhathi ingxenye eyisiphambano iba sesimweni sohlamvu lwesiJapane oluthi "ひ".
Izinga lakamuva liyizinga elinconyiwe likazwelonke elakhishwa ngo-2008 futhi lasetshenziswa ngo-April 1, 2009.
I-GB/T 4697-2008
Ukusekelwa kwensimbi okumise okwe-U
Izici eziyinhloko: ingcindezi enkulu, isikhathi eside sokusekela, ukufakwa okulula kanye nokuguqulwa okulula.
Ukusetshenziswa okuyinhloko: isetshenziselwa ukusekelwa kwesibili komgwaqo wezimayini, umgwaqo wezimayini, kanye nokusekelwa komhubhe wasezintabeni.
Insimbi emise okwe-U isetshenziswa kabanzi ekhaya nakwamanye amazwe njengensimbi yesigaba esikhulu sokukhiqiza ukusekelwa kwensimbi okuhoxiswayo komgwaqo.
Kodwa-ke, ngenxa yokuqonda okuhlukile kwezakhiwo kanye nezidingo zensimbi e-U-shaped, ukuma kwe-cross-sectional, imingcele yejometri kanye nezinto zensimbi e-U-shaped zihlukile emazweni ahlukene.
Kunezinhlobo ezine zensimbi emise okwe-U ekhiqizwa eChina: 18u, 25U, 29U kanye 36U. Phakathi kwazo, ezimbili zokuqala ziyimikhiqizo yeminyaka yawo-1960, ehambisana nokubeka okhalweni; Okubili kokugcina kuyimikhiqizo yama-1980s, ehambisana nokuma kwendlebe. I-U18 ayivamisile ukukhiqizwa ngenxa yomthamo wayo ophansi wokuthwala.
Ku-GB / T 4697-2008, i-40u yengezwa ngaphezu kwezinhlobo ezine ezingenhla zensimbi emise u-U.
Isisindo seyunithi yohlobo ngalunye lwensimbi emise okwe-U lumi kanje:
18UY 18.96 kg/m
25UY 24.76 kg/m
25U 24.95 kg/m
29U 29 kg/m
36U 35.87 kg/m
40U 40.05 kg/m
Lapho imodeli eno-"Y" ngemuva ikhombisa ukuma okhalweni.
Uhlobo lwegama lensimbi emise okwe-U: insimbi emise okwe-U ebandayo, enosayizi omkhuluInsimbi emise okwe-U, insimbi emise okwe-U yemoto, insimbi eyisipesheli ediphu eshisayo emise okuka-U kanye nenye insimbi epholile eyakhelwe ngaphakathi evulekile.
Ngemidwebo yobuchwepheshe namamodeli we-3-D, chofoza inombolo yengxenye.
Izitifiketi ezinenombolo yenkatho elandelekayo ziyatholakala kule mikhiqizo. Landa izitifiketi kusukaODA UMLANDOngemva kokuthunyelwa kwe-oda lakho.

IZINGA ELIFANELEKILE LEMIKHIQIZO >100%
A: Siyimboni.
A: Ngokuvamile kuba yizinsuku ezingu-5-10 uma izimpahla zisesitokweni. noma yizinsuku ezingama-30 uma izimpahla zingekho esitokweni, kuhambisana nenani.
IMP: Yebo, singanikeza isampula ngenkokhiso yamahhala nezindleko zomthwalo okhokhelwa ikhasimende.
A: Inkokhelo<=1000USD, 100% kusengaphambili. Inkokhelo>=1000USD 30% T/T kusengaphambili ,ibhalansi ngaphambi kokuthunyelwa.Uma unomunye umbuzo, pls zizwe ukhululekile ukusithinta njengoba ngezansi
Inkampani ibheka ukubaluleka okukhulu kwekhwalithi yemikhiqizo, itshala imali eningi ekwethulweni kwemishini ethuthukisiwe nochwepheshe, futhi iphuma konke ukuze ihlangabezane nezidingo zamakhasimende ekhaya naphesheya.
Okuqukethwe kungahlukaniswa cishe kube: ukwakheka kwamakhemikhali, amandla okukhiqiza, amandla okudonsa, impahla yomthelela, njll
Ngasikhathi sinye, inkampani ingakwazi futhi ukuthola amaphutha ku-inthanethi kanye nokukhipha ama-anneal nezinye izinqubo zokwelapha ukushisa ngokwezidingo zamakhasimende.
