Waa maxay noocyada birta kaarboon?
1, birta qaab dhismeedka kaarboon:
Isticmaalka ugu muhiimsan: dhammaan noocyada injineernimada.Caadi ahaan waxaa lagu bixiyaa qaboojin hawo ah ka dib duubista kulul, Isticmaalayaashu guud ahaan uma baahna inay kululeeyaan daaweynta iyo isticmaalka tooska ah.Waxaa jira shan darajo oo birtan ah iyadoo loo eegayo xooggooda wax-soo-saarka.Calaamadaha darajada: A, B, C, D (GradeD waxa ay gaadhay heerka birta tayada sare leh)
2, birta qaab dhismeedka carbon tayo sare leh:
Isticmaalka ugu muhiimsan: qaybo muhiim ah.Qalabka farsamada ee qaybaha waxaa lagu hagaajin karaa daaweynta kulaylka Noocyada caadiga ah ee la isticmaalo: 08F, 10#, 15#, 20#, 35#, 45#, 60#, iwm.
3, birta qalabka kaarboon (WC = 0.65% ~ 1.35% waa bir kaarboon sare leh):
Isticmaalka ugu muhiimsan: samaynta qalabyo yaryar oo kala duwan.Adkeysiga sare iyo iska caabbinta xirashada waxaa lagu heli karaa deminta iyo heerkulka hooseeya.Waxa loo qaybiyaa laba qaybood oo tayo sare leh iyo tayo sare leh.
4, injineernimada guud tuur kaarboon birta ah (kabka birta):
Isticmaalka ugu muhiimsan: adag tahay in la sameeyo by been abuur ah iyo riixaya iyo hababka kale ee qaybaha adag iyo shuruudaha guryaha farsamo sare;
Labadii sano ee la soo dhaafay, Saldhigga dhoofinta shabakadeena ayaa dhoofisay in ka badan 30 waddan iyo gobollo macaamiisha ah ee 3 qaaradood.Dhoofinta birta 200,000 oo tan, iibka isugeynta ah ee 1 bilyan yuan.Baakad: Xidhmo leh xariijimo bir ah ama ku xidhxidhan alwaaxyo alwaax ah ama sida looga baahan yahay macaamiisha.dhoofinta: Waxaan la leenahay iskaashi muddo dheer ah shirkado badan oo maraakiibta khibrad leh oo waxaan kuu heli doonaa habka ugu habboon ee gaadiidka adiga.
S: Waa maxay sababta noo dooratay?
A: Shirkaddayadu waxay ku jirtay ganacsi bir ah in ka badan toban sano, waxaanu nahay khibrad caalami ah, xirfad leh, waxaanan ku siin karnaa noocyo kala duwan oo alaabooyin bir ah oo tayo sare leh macaamiisheena.S: Ma waxaad tahay shirkad ganacsi ama soo saaraha?A: Waxaan nahay soo saaraha, waxaan leenahay 12 sano oo waayo-aragnimo ah bixinta qalabka biraha iyo alaabta ee Shiinaha, oo leh Alibaba Gold Member iyo SGS shahaado Q: Miyaad bixisaa muunado?ma bilaash baa mise waa dheeraad ?J: Dabcan, waxaan macaamiisha siin karnaa muunado bilaash ah iyo adeegga maraakiibta degdega ah ee adduunka oo dhan S: Ma booqan karnaa warshadaada?J: Si diiran u soo dhawoow.Marka aan haysano jadwalkaaga, waxaanu diyaarin doonaa kooxda iibka xirfadlayaasha ah si ay ula socdaan kiiskaaga.S: Maxay yihiin faa'iidooyinka shirkaddaada?A: Waxaan leenahay xirfadlayaal badan, shaqaale farsamo, qiimo badan oo tartan ah iyo adeegga ugu fiican ee ka dambeeya shirkadaha kale ee birta ah.S: Waa intee wakhtiga dhalmadaada?J: Alaabtayada maalinlaha ah waxay ka badan tahay 8000 tan, markaa cabbirka alaabta caadiga ah, kaliya waxay u baahan yihiin 5 maalmood kaydka;haddii cabbirka gaarka ah ee wax soo saarka cusub, gaarsiinta 7-15 maalmood.S: Waa maxay shuruudaha lacag bixinta?A: Bixinta <= 1000USD, 100% ka hor.Lacag bixinta> = 1000USD, 30% T / T ka hor, dheelitirka ka hor inta aan la rarin.
