Qhia luv luv rau kev soj ntsuam xyuas ntawm Seamless Calcium Hlau
I. Internal Control Standards
Cov tshuaj muaj pes tsawg leeg ntawm calcium core: Ca Ntau dua lossis sib npaug li 97%
Nominal txoj kab uas hla ntawm cov tub ntxhais hlau: 9.0 mus rau 9.0+0.6mm; thickness ntawm steel sawb: 1.0±0.05mm;
Qhov hnyav yuav tsum tau ib 'meter' ntawm cov tub ntxhais hlau: cov calcium core hnyav Ntau dua los yog sib npaug rau 52g / m, thiab qhov hnyav ntawm cov hlau strip Tsawg dua los yog sib npaug rau 210g / m
Ua ntej txheej steel sawb, nws yuav tsum tau degreased thiab derusted. Cov calcium core yuav tsum tau khaws cia qhuav thiab tsis pub sib xyaw nrog lwm cov impurities. Cov tub ntxhais hlau yuav tsum tau ua kom ruaj khov yam tsis muaj qhov xau ntawm cov tub ntxhais, tsis muaj qhov qhib ntawm cov seams, tsis muaj kev cuam tshuam ntawm cov xov hlau, tsis muaj txheej txheej cuav, thiab tsis muaj roj thiab xeb ntawm qhov chaw.
Kev ntim khoom: qhov hnyav ntawm cov ncej hlau yuav tsum ua tau raws li cov kev cai dav dav ntawm cov tub ntxhais hlau. Sab nrauv ntawm cov khoom yuav tsum tau nruj nreem qhwv nrog ib tug yas zaj duab xis, thiab ib tug uas tsis yog-fading kos npe rau sab nraum yuav tsum tau cim nrog lub npe, lub ntsiab ntsiab lus, qhov loj, qhov hnyav, chav tsev tsim khoom, thiab hnub tsim khoom.
II. Txoj Kev Txais:
Purity ntawm hlau calcium: Thaum cov hlau Ca tsawg dua 97%, rau txhua txhua 0.01% txo qis dua 97%, tus nqi raug txo los ntawm 5 yuan / tuj.
Thaum qhov hnyav ntawm cov calcium core tsawg dua 52g / m, rau txhua 1g / m txo qis dua 52g / m, tus nqi raug txo los ntawm 300 yuan / tuj; rau txhua txhua 1g / m nce nyob rau hauv qhov hnyav ntawm steel sawb tshaj, tus nqi raug txo los ntawm 10 yuan / ton.
Thaum Ca tsawg dua 95% lossis qhov hnyav ntawm cov ntsiab lus calcium tsawg dua 47g / m, tus neeg yuav khoom muaj cai tsis lees txais lossis sib tham txog kev daws teeb meem.
