Kev twv ua ntej thiab kev tshawb fawb ntawm cov muaj peev xwm ntawm cov dawb cov dub dub nyob rau hauv Suav teb 2018-2022
Nyob rau hauv xyoo tas los no, vim yog qhov zoo heev reinforcing kev ua tau zoo ntawm cov dawb cov dub, cov roj dawb hauv cov roj hmab thiab cov khoom yas ua tau zoo heev, thiab cov zis dub dawb hauv Suav tau nce ntau zog.
Dawb cov dub dub yog lub npe ntawm cov hmoov dawb X - - duab ci amorphous silicic acid thiab silicate khoom. Dawb cov roj dub yog ib cov khoom ntxeem tau, nws muaj pes tsawg tus yuav qhia tau los ntawm SiO2 nH2O, uas nyob rau hauv daim ntawv ntawm ntu hydroxyl. Raws li txoj kev ntawm cov khoom, cov dawb cov roj dub yuav muab faib ua cov roj theem dawb cov roj dub thiab nag lossis daus txoj dawb cov roj dub.
Raws li tus phooj ywg zoo thiab zoo heev, silica yog siv los ua cov khoom siv roj hmab, nrog rau kev kub siab vulcanized silicone roj hmab, textile, ntawv ua, tshuaj tua kab thiab khoom noj. Nyob rau hauv xyoo tas los no, vim kev ua kom tiav zoo ntawm cov xim dawb dub, yuav tsum tau cov xim dawb hauv cov roj hmab thiab yas khoom zoo heev, thiab cov pa roj carbon dawb hauv Suav teb tau nce ceev ceev.
Ua tsaug rau txoj kev loj hlob ntawm kev lag luam ntawm lub log tsheb, kev lag luam roj hmab, kev lag luam thiab lub zog tshiab, nws yog kwv yees tias txhua xyoo kev thov kev lag luam ntawm precipitated silica yuav mus txog 10% yav tom ntej. Nyob rau hauv lub neej yav tom ntej, txoj kev loj hlob ntawm silica yuav los ntawm kev thov kev loj hlob ntawm txoj kev lag luam. Nrog rau kev thov kom tis meridian, kev tiv thaiv ib puag ncig, lub zog txuag thiab kev nplij siab, daim ntawv thov ntawm silica yuav ua ntau dua thiab tseem ceeb. Nyob rau hauv xyoo tas los, precipitated silica tau siv dav hauv cov log ntawm cov log tsheb, cov log tsheb thiab cov log tsheb ntsuab. Nws yuav tsum tau hais tias qhov kev thov rau cov dawb carbon cov lag luam yuav loj hlob ntawm tus nqi sai dua yav tom ntej.
Kev twv ua ntej ntawm cov pa roj carbon ntau lawm
Nyob rau hauv 2015, lub peev xwm ntawm cov av nplaum dawb dub nyob rau hauv Suav teb yog 1 lab 990 txhiab tons. Peb cia siab tias hauv xyoo 2018, lub peev xwm ntawm cov khoom tsim tau los ntawm ntau qhov chaw yuav tau muaj 2 lab 60 txhiab tons hauv xyoo 2018, thiab txhua xyoo qhov kev loj hlob yog 1.12% hauv tsib xyoos tom ntej no (2018-2022), thiab nws yuav mus txog 2 lab 150 txhiab tons nyob rau hauv 2022.
