Recycled roj hmab yog ib qho tseem ceeb nyob rau hauv ntau yam lag luam thiab yog tsim los ntawm cov txheej txheem sophisticated hu ua high-temperature dynamic desulfurization. Txoj kev no tau siv dav hauv cov chaw tsim khoom lag luam thiab koom nrog ntau cov kauj ruam los hloov cov khoom siv roj hmab pov tseg rau hauv cov peev txheej muaj txiaj ntsig nrog kev ua haujlwm tshiab thiab ntau yam.
Thawj kauj ruam hauv kev tsim cov roj hmab rov qab yog kev sau cov khoom siv roj hmab, uas tuaj yeem tshwm sim los ntawm ntau qhov chaw xws li cov log tsheb uas tsis muaj log, cov hlua conveyor, thiab cov khoom siv roj hmab. Cov ntaub ntawv no feem ntau raug txheeb xyuas thiab ntxuav kom tshem tawm cov kab mob, kom ntseeg tau qhov zoo thiab purity ntawm cov khoom kawg.
Thaum cov khoom siv roj hmab tau npaj, nws dhau los ua cov txheej txheem desulfurization, uas yog lub hauv paus ntawm cov khoom siv roj hmab rov qab. High-temperature dynamic desulfurization muaj feem xyuam rau daim ntawv thov ntawm tshav kub thiab siab nyob rau hauv lub xub ntiag ntawm roj. Qhov kub tuaj yeem ncav cuag 280 degree, tsim kom muaj ib puag ncig zoo rau kev tawg ntawm molecular bonds hauv cov roj hmab matrix.
Thaum lub sij hawm devulcanization, cov roj hmab tau o, tso cai rau cov roj nkag mus rau hauv cov qauv molecular thiab pab txhawb kev sib cais ntawm sulfur cross-links. Cov txheej txheem no zoo thim rov qab cov vulcanization uas tshwm sim thaum pib ntawm cov khoom siv roj hmab, rov qab kho cov khoom mus rau lub xeev ntau dua thiab ua haujlwm tau.
Ntxiv rau qhov kub thiab txias, oxidative cleavage plays lub luag haujlwm tseem ceeb hauv cov txheej txheem desulfurization. Ntxiv oxidants rau cov sib tov txhawb kev puas tsuaj ntawm cov tshuaj bonds thiab ntxiv txhawb cov dispersion ntawm roj hmab molecules nyob rau hauv cov roj nruab nrab. Cov kauj ruam no txhim kho desulfurization efficiency thiab pab txhim kho tag nrho cov khoom zoo ntawm cov roj hmab rov qab.
Thaum cov txheej txheem devulcanization tiav, cov khoom siv tau raug kho kom tshem tawm cov impurities thiab ua tiav qhov xav tau sib xws thiab cov khoom. Qhov no yuav suav nrog kev pom, centrifugation, lossis lwm yam kev ua kom huv huv kom ntseeg tau tias cov roj hmab rov qab ua tau raws li cov qauv kev lag luam rau kev ua haujlwm thiab ua haujlwm ntev.
Cov khoom kawg, cov roj hmab rov ua dua tshiab, muaj cov khoom zoo sib xws rau cov roj hmab nkauj xwb, ua rau nws tsim nyog rau ntau yam kev siv hauv kev lag luam xws li tsheb, kev tsim kho thiab kev tsim khoom. Nws tuaj yeem siv ib leeg lossis sib xyaw nrog cov roj hmab nkauj xwb los txo cov nqi, nce kev ruaj khov thiab txhim kho cov khoom lag luam.
Hauv kev xaus, high-temperature dynamic devulcanization yog ib txoj hauv kev zoo rau kev tsim cov roj hmab rov qab. Los ntawm kev siv cov cua sov, siab, thiab oxidative cov neeg ua haujlwm, cov txheej txheem no hloov cov ntaub ntawv pov tseg rau hauv cov ntaub ntawv tseem ceeb nrog kev ua haujlwm tshiab thiab ntau yam, pab txhawb kev siv cov peev txheej hauv ntau yam lag luam.
