Hauv kev kho cov dej phwj tuaj ntawm cov roj av, muaj ib qho teeb meem uas cov dej phwj tuaj yeem ua tsis tau raws li tus qauv. Muaj ntau yam uas ua rau muaj qhov xwm txheej no, qhov tseem ceeb tshaj plaws yog qhov teeb meem ntawm lub lim.
Kev lim dej yog qhov chaw kawg uas tshem tawm cov khib nyiab thiab roj. Txhawm rau ua kom tau raws li cov qauv sib xws, cov khoom raug tshem tawm, roj thiab algae raug cuam tshuam thiab adsorbed. Daim ntawv thov hloov kho fiber ntau lim hauv nws tuaj yeem txhim kho kev kho mob zoo.
Cov yam ntxwv tsom xam ntawm Hloov Kho Fiber Pob Lim
Cov hlau txoj kab uas hla yog me me, thiab thaj chaw saum npoo tuaj yeem ncav cuag 2000 square meters ib gram. Tom qab ua haujlwm tau zoo, qhov porosity tuaj yeem lav tau siab dua 80 feem pua, thiab cov nyhuv tuav tau zoo dua li cov khoom siv lim dej.
Hloov kho fiber ntau lim yog hydrophilic thiab tsis-stick roj. Tom qab ntsib dej, ntau cov dej molecules yuav sib sau ua ke ntawm cov fiber ntau filaments thiab tsim ib txheej ntawm cov dej zaj duab xis rau saum npoo, uas ua lub luag haujlwm zoo hauv kev sib cais cov roj ntawm fiber ntau hauv av.
Los ntawm kev thim rov qab, cov roj stains ntawm qhov chaw ntawm lub pob fiber ntau tuaj yeem raug tshem tawm, thiab nws muaj kev tsim kho dua tshiab.
Lub mechanism ntawm organic teeb meem / roj tshem tawm los ntawmhloov kho fiber ntauyog: inertial interception, direct interception thiab electrochemical adsorption.
Cov roj cov ntsiab lus ntawm cov dej ua ntej pom yog tsawg dua los yog sib npaug rau 15mg / L, thiab cov teeb meem raug tshem tawm tsawg dua lossis sib npaug li 10mg / L; cov roj cov ntsiab lus ntawm cov dej lim yog tsawg dua los yog sib npaug li 5mg / L, thiab cov teeb meem raug tshem tawm tsawg dua lossis sib npaug li 2mg / L.
Qhov saum npoo ntawm lub pob fiber ntau yog hloov kho kom muaj peev xwm adsorption ntawm cov roj thiab cov organic teeb meem; nyob rau hauv cov kev hloov kho fiber ntau pob ligation txoj kev, lub porosity ntawm lub lim txheej maj mam txo nyob rau hauv cov kev taw qhia ntawm cov dej ntws thaum lub sij hawm ua hauj lwm, tsim ib tug zoo tagnrho lim khoom.
Nyob rau hauv lub pore faib lub xeev, cov nyhuv pom zoo dua; qhov pom ceev yog siab, mus txog 25-30m/h. Cov khoom siv lim tsuas yog yuav tsum tau rov ua dua li ntawm 10 feem pua txhua xyoo, thiab tsis tas yuav hloov nws.
Qhov sib txawv loj tshaj plaws ntawm cov khoom siv fiber ntau hloov thiab cov khoom siv fiber ntau yog tias lawv yog cov khoom siv polymer nrog cov khoom tsis zoo dyeing, uas txawv ntawm textiles.
Nws muaj qhov zoo ntawm cov nyhuv zoo, siab precision, yooj yim tu thiab kev pab lub neej ntev, thiab yog siv dav hauv kev kho dej phwj hauv cov roj av, petrochemicals, luam ntawv thiab dyeing thiab lwm yam lag luam.
Hloov kho fiber ntau pob lim ua haujlwm txoj cai:
Cov teeb meem raug tshem tawm ntawm cov khoom siv yuav khaws cia rau saum npoo ntawm qhov nruab nrab, thiab lub ncuav mog qab zib lim yuav raug tsim los ntawm kev sib txuas, pom thiab lwm yam txheej txheem los txhim kho qhov pom tseeb. Nyob rau tib lub sijhawm, cov pores ntawm cov khoom siv lim yuav raug txo, ua kom pom kev ua haujlwm.
Thaum qhov kev tawm tsam nce mus rau qee qhov, kev sib txuas ntawm kev sib txuas yuav raug puas tsuaj los ntawm kev cuam tshuam ntawm cov khoom ncua kev ncua, thiab cov khoom loj dua tshiab yuav hloov cov kev sib raug zoo ntawm kev sib txuas thiab txuas ntxiv lim cov khib nyiab hauv cov dej phwj tuaj.
Kev sib piv ntawm Hloov Kho Fiber Pob Lim nrog Lwm Cov Lim Media
Walnut plhaub cov khoom siv: muaj zog adsorption muaj peev xwm, siab hardness, hnav tsis kam, thiab muaj peev xwm lim loj, tab sis cov nyhuv ntawm kev tshem tawm cov khib nyiab hauv cov dej phwj tuaj tsis zoo.
Ob txheej txheej lim khoom lim: muaj zog av tuav lub peev xwm, kev ua haujlwm yooj yim, kev ua haujlwm yooj yim thiab kev tswj hwm, tsim nyog rau kev kho dej phwj siab.
Quartz xuab zeb lim: cov cuab yeej siv dav tshaj plaws hauv cov roj av kev kho dej tam sim no, vim nws cov qauv yooj yim, kev saib xyuas yooj yim thiab kev ua haujlwm yooj yim, nws muaj cov dej phwj tuaj zoo.
Raws li hom tshiab ntawm cov dej phwj tuaj lim dej zoo, cov khoom siv fiber ntau hloov pauv tau pom tseeb qhov zoo: suav nrog hydrophilic thiab oleo phobic, thaj chaw loj tshwj xeeb, porosity siab, kev ua haujlwm zoo, thiab lwm yam, thiab qhov zoo yog pom tseeb dua hauv qis- permeability roj txheej. Ua haujlwm. , uas tuaj yeem ua tiav qhov kev pom zoo siab thiab ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ruaj khov ntawm kev lag luam oilfield.
