Silica Fume Rau Hauv Pob Zeb Ua

silica fume hauv pob zeb ua

Microsilica hmoov rau 92% cov pob zeb ua haujlwm: Cov tsos yog grey hmoov, SiO2 cov ntsiab lus yog li 92-94%, nrog cov khoom siv encryption siab kawg thiab semi-encryption, tuaj yeem thov rau cov pob zeb loj, kev ua haujlwm siab, choj thiab lwm yam dej num, raws li tsim nyog admixture.

Keeb kwm ntawm micro silicon hmoov

Thawj qhov tau hais nyob hauv Asmeskas daim ntawv lees paub xyoo 1947

Thawj cov pob zeb ua kev sim tau ua rau hauv Norway xyoo 1950

Thawj daim ntawv thov hauv kev lag luam pob zeb hauv xyoo 1971

Tso cai rau pob zeb ua hauv Norway nyob rau thaum xyoo 1970s

Xyoo 1980 Norway ua tau txog 55,000 tons / xyoo

Cov qauv khoom hauv 1987 (Canada, ASTM, thiab lwm yam)

Txij li cov kev tiv thaiv ib puag ncig tiv thaiv kev tiv thaiv hauv xyoo 2000, ntau ntau ntawm kev tsim khoom tau sau thiab siv dav.

Raws li qhov sib txawv ntawm qhov sib txawv, nws tau muab faib ua peb hom micro silica:

1. Cov micro-silicon hmoov rau sau cov hmoov av ncaj qha, uas peb hu ua cov hmoov tshauv, nws qhov ntau yog 130 ~ 180kg / m3.

2. Rau qhov yooj yim ntawm kev thauj mus los thiab engineering daim ntawv thov, cov tshauv thawj yog encrypted. Lub tshuab zais silicon muaj qhov ceev ntawm 320-350kg / m3 rau kev sau ib nrab. Tej qhov cim tseg ntawm 600-700kg / m3 tau tag nrho encrypted.

Ntim& Cia ntawm Silica Fume

Silica fume ntim rau hauv 25-kg Thiab 1 tuj ntim ntau lub phab ntsa ntawv hnab nrog polyethylene hnab. Nws yog qhov tsim nyog yuav tsum tau muab cia rau hauv qhov chaw qhuav kom deb ntawm qhov chaw ntawm cov cua sov lossis qhov quav, thiab txo cov plua plav.

Cim npe nrov: silica fume hauv pob zeb ua, Tuam Tshoj, cov chaw muag khoom, lub Hoobkas, lag luam wholesale, yuav, customized, nqi, ua nyob rau hauv Suav teb
