Feem ntau hais lus, SBS hloov kho ntawm bitumen yuav tsum muaj peb txheej txheem: o, shearing (los yog sib tsoo), thiab kev loj hlob.
Rau SBS hloov bitumen system, muaj kev sib raug zoo ntawm o thiab kev sib raug zoo. Qhov loj ntawm qhov o ncaj qha cuam tshuam rau kev sib raug zoo. Yog tias SBS swells infinitely nyob rau hauv bitumen, lub kaw lus yuav ua tau tag nrho. Tus cwj pwm o yog ze ze rau kev tsim khoom, kev siv thev naus laus zis thiab kev kub siab cia ruaj khov ntawm kev hloov kho bitumen. Raws li qhov kub thiab txias nce, qhov o tus nqi nrawm nrawm dua, thiab qhov o yog pom tseeb ntawm cov txheej txheem melting kub siab dua li cov iav hloov kub ntawm PS ntawm SBS. Tsis tas li ntawd, cov qauv ntawm SBS muaj qhov cuam tshuam loj rau tus cwj pwm o: qhov o ceev ntawm lub hnub qub zoo li SBS qeeb dua li ntawm linear SBS. Cov ntaub ntawv txheeb xyuas qhia tau hais tias qhov ntom ntawm SBS cov khoom o ntawm cov khoom yog concentrated ntawm 0.97 thiab 1.01g / cm3, uas yog ze rau qhov ntom ntawm cov tshuaj tsw qab phenols.
Shearing yog ib kauj ruam tseem ceeb ntawm tag nrho cov txheej txheem hloov kho, thiab cov nyhuv ntawm shearing feem ntau cuam tshuam rau qhov kawg tshwm sim. Lub pob zeb colloid yog lub hauv paus ntawm cov cuab yeej hloov kho bitumen. Nws ua haujlwm nyob rau hauv qhov kub thiab txias ib puag ncig. Lub txheej txheej ntawm lub pob zeb colloid yog lub tsho qauv nrog lub voj voog ncig. Nws kuj ua lub luag haujlwm ntawm kev poob siab thiab txo suab nrov. Sab hauv ntawm lub pob zeb colloid yog Lub voj voog txav disc thiab cov annular taag disc nrog qee tus lej ntawm cov hniav yog siv los zom cov riam. Qhov sib txawv tuaj yeem hloov kho. Lub uniformity ntawm cov khoom particle loj thiab cov nyhuv peptization yog txiav txim los ntawm qhov tob thiab dav ntawm cov hniav slots, tus naj npawb ntawm sharpening riam, thiab cov kev ua hauj lwm ntawm kev tsim cov qauv. txiav txim los ntawm cheeb tsam. Raws li lub phaj txav txav ntawm kev kub ceev, tus hloov kho yog tsis tu ncua dispersed los ntawm muaj zog shear thiab kev sib tsoo, sib tsoo cov hais mus rau hauv zoo hais, thiab tsim ib tug ruaj khov miscible system nrog bitumen kom tiav lub hom phiaj ntawm uniform blending. Tom qab tag nrho o, SBS thiab bitumen sib tov sib npaug. Qhov me me ntawm cov khoom sib tsoo, qhov siab dua qhov sib txawv ntawm SBS hauv bitumen, thiab qhov ua tau zoo ntawm kev hloov kho bitumen. Feem ntau, txhawm rau ua tiav cov txiaj ntsig zoo, kev sib tsoo tuaj yeem ua tiav ntau zaus.
Kev tsim cov hloov kho bitumen thaum kawg mus los ntawm txoj kev loj hlob. Tom qab sib tsoo, cov bitumen nkag mus rau hauv cov khoom tiav tank los yog kev loj hlob tank. Qhov kub yog tswj ntawm 170-190 ° C, thiab cov txheej txheem kev loj hlob yog nqa tawm rau qee lub sijhawm nyob rau hauv qhov kev txiav txim ntawm lub tov khoom. Hauv cov txheej txheem no, qee yam hloov kho bitumen stabilizer feem ntau ntxiv los txhim kho kev ruaj ntseg cia ntawm cov hloov bitumen. Cov xwm txheej tam sim no ntawm SBS hloov kho bitumen ntau lawm tshuab
. Tuam Tshoj tsim tawm kwv yees li 8 lab tons ntawm SBS hloov bitumen rau txoj kev txhua xyoo, thiab cov khoom siv zoo tshaj plaws thiab kev siv tshuab yog nyob hauv Suav teb. Ceev faj ntawm kev dag thiab kev dag ntxias los ntawm cov chav kawm comprador;
2. Tom qab ze li ntawm 60 xyoo ntawm txoj kev loj hlob, lub tshuab ntawm SBS hloov bitumen tau mus txog lub qab nthab nyob rau theem no. Yog tsis muaj kev hloov pauv hloov pauv, yuav tsis muaj kev siv tshuab;
Thib peb, nws tsis muaj dab tsi ntau dua li kev hloov kho dua tshiab thiab sim sib xyaw ntawm plaub cov ntaub ntawv: lub hauv paus bitumen, SBS modifier, blending oil (arromatic oil, synthetic oil, naphthenic oil, etc.), thiab stabilizer;
3. Tsav tsheb nplua nuj tsis muaj dab tsi ua rau kev tsav tsheb. Imported mills thiab high-end khoom tsis sawv cev rau qib ntawm kev hloov kho bitumen technology. Rau qhov loj, lawv tsuas yog qhia tawm peev. Nyob rau hauv cov nqe lus ntawm kev ruaj ntseg ntsuas, tshwj xeeb tshaj yog los xyuas kom meej cov txheej txheem tshiab qhia, sib tsoo-dawb ntau lawm xws li Rizhao Kishijia tuaj yeem lav ntau dua;
4. Cov tuam txhab lag luam hauv xeev xws li Provincial Kev Lag Luam Kev Lag Luam thiab Kev Tswj Xyuas tau npaj rau kev tsim khoom thiab kev ua haujlwm ntawm SBS hloov bitumen, thiab lawv tau ua lub xeev. Cov nplai loj loj. Ntxiv rau kev sib tw rau cov txiaj ntsig nrog cov neeg, lawv tsis tuaj yeem sawv cev qib siab lossis kev tsim khoom tshiab;
5. Nws yog qhov yuav tsum tau ceev nrooj los tsim cov cuab yeej saib xyuas online thiab cov cuab yeej siv los ua kom cov txheej txheem tswj tau;
6. Hauv kev ua lag luam Hiav Txwv Liab, cov txiaj ntsig tsis muaj txiaj ntsig, uas tau ua rau ntau qhov kev hloov kho "trinitrile amine".
