O a ituaiga o uamea carbon?
1, uamea fausaga carbon:
Fa'aoga autu: ituaiga uma o inisinia.E masani ona tuʻuina atu e le malulu ea pe a uma le vevela, E masani ona le manaʻomia e tagata faʻaoga le vevela togafitiga ma faʻaoga saʻo.E lima togi o lenei uamea e tusa ai ma lo latou malosi e maua ai.Fa'ailoga togi: A, B, C, D (VaegaD e o'o i le maualuga o le sila maualuga)
2, maualuga maualuga carbon fausaga uamea:
Fa'aoga autu: vaega taua.O mea faʻainisinia o vaega e mafai ona fetuʻunaʻi e ala ile vevela Faʻailoga masani faʻaaogaina: 08F, 10 #, 15 #, 20 #, 35 #, 45 #, 60 #, ma isi.
3, uamea meafaigaluega carbon (WC = 0.65% ~ 1.35% o maualuga carbon sila):
Fa'aoga autu: fai mea faigaluega laiti eseese.E mafai ona maua le maaa maualuga ma le ofuina e ala i le tineia ma le maualalo o le vevela.E vaevaeina i ni vaega se lua o le maualuga ma le maualuga.
4, fa'ainisinia lautele lafo carbon sila (ua lafo u'amea):
Fa'aoga autu: faigata ona fa'atupuina e ala i le u'u ma le oomi ma isi metotia o vaega lavelave ma mana'oga maualuga fa'ainisinia;
I le lua tausaga ua tuanaʻi, ua faʻatau atu e le matou nofoaga faʻatau atu fesoʻotaʻiga le sili atu i le 30 atunuu ma itulagi ma tagata faʻatau i 3 konetineta.Uamea auina atu i fafo 200, 000 tone, fa'aputu fa'atauga o le 1 piliona yuan.Fa'apipi'i: Fa'atasi ma le fasi uamea po'o le fa'aputuina i fata laupapa po'o le mana'oga o tagata fa'atau.Va'a: E iai a matou felagolagoma'i umi ma le tele o kamupani va'a poto masani ma o le a maua le auala sili ona talafeagai o felauaiga mo oe.
Q: Aisea e filifili ai i matou?
A: O la matou kamupani sa i ai i pisinisi uʻamea mo le sili atu ma le sefulu tausaga, matou te iloa faʻavaomalo, faʻapitoa, ma e mafai ona matou tuʻuina atu ituaiga oloa uʻamea ma maualuga maualuga i a matou tagata faʻatau.Q: O oe kamupani fefa'ataua'iga po'o le gaosiga?A: O matou o le gaosiga, matou te maua le 12 tausaga le poto masani i le tuʻuina atu o mea uʻamea ma oloa i Saina, faʻatasi ai ma Alibaba Gold Member ma SGS faʻamaonia Q: E te tuʻuina atu faʻataʻitaʻiga?e leai se totogi pe fa'aopoopo ?A: Ioe, e mafai ona matou tuʻuina atu i tagata faʻatau ni faʻataʻitaʻiga e leai se totogi ma faʻaalia auaunaga faʻasalalau i le lalolagi atoa Q: E mafai ona matou asiasi i lau fale gaosimea?A: Fa'afeiloa'i māfana.O le taimi lava e maua ai lau faʻatulagaga, matou te faʻatulagaina le au faʻatau faʻapolofesa e tulitatao lau mataupu.Q: O a mea lelei o lau kamupani?A: E tele a matou polofesa, tagata faigaluega faʻapitoa, tau faʻatauvaʻa ma sili atu le auaunaga i tua atu nai lo isi kamupani uʻamea.Q: O le a le umi o lau taimi tuʻuina atu?A: O a matou faʻamaumauga i aso uma e sili atu i le 8000 tone, o lea mo le tele o oloa masani, naʻo le manaʻomia 5 aso mai faʻatau;pe afai o le tele faʻapitoa mai le gaosiga fou, tuʻuina atu 7-15 aso.Q: O a au tuutuuga o le totogiina?A: Totogi<= 1000USD, 100% muamua.Totogi> = 1000USD, 30% T / T muamua, paleni aʻo leʻi lafoina.
