Sepiolite fiber yog ib hom fiber ntuj, uas yog ntau yam fibrous ntawm sepiolite mineral, hu ua α - sepiolite. Sepiolite yog ib hom layered chain silicate mineral. Hauv cov qauv ntawm sepiolite, ib txheej ntawm magnesia octahedron yog sandwiched ntawm ob lub silicon oxygen tetrahedrons, tsim ib hom 2: 1 hom layered qauv unit. Lub txheej tetrahedral yog tas mus li thiab kev coj ntawm cov pa oxygen hauv txheej yog rov qab tsis tu ncua. Lub txheej octahedral tsim ib txoj kab sib dhos ntawm cov txheej sab saud thiab qis. Lub channel orientation yog sib xws nrog lub fiber axis, tso cai rau cov dej molecules, hlau cations, organic me me molecules thiab lwm yam kom nkag mus. Sepiolite muaj kev tiv thaiv cua sov zoo. Sepiolite kuj muaj cov khoom pauv ion zoo thiab catalytic, nrog rau kev tiv thaiv corrosion, tiv thaiv hluav taws xob, rwb thaiv tsev, rwb thaiv tsev cua sov thiab lwm yam khoom zoo heev, tshwj xeeb tshaj yog Si Oh hauv nws cov qauv tuaj yeem cuam tshuam ncaj qha nrog cov organics los tsim cov organic mineral derivatives.
Sepiolite kuj tseem siv dav hauv kev ntxuav, kev ua kom zoo tshaj plaws thiab kev hloov kho. Sepiolite tuaj yeem siv ua adsorbent, purifier, deodorant, reinforcing agent, suspending agent, thixotropic agent, filler, thiab lwm yam hauv kev kho dej, catalysis, roj hmab, txheej, tshuaj chiv, pub thiab lwm yam lag luam. Tsis tas li ntawd, sepiolite muaj kev tiv thaiv ntsev zoo thiab tiv taus kub siab, yog li nws tuaj yeem siv ua cov khoom siv av nkos zoo hauv kev khawb roj, geothermal drilling thiab lwm yam.
Sepiolite fiber yog cov khoom siv fiber ntau, uas tau los ntawm cov pob zeb fibrous minerals. Nws cov khoom tseem ceeb yog ntau yam oxides, xws li silica, alumina, magnesium oxide, thiab lwm yam. Nws cov khoom tseem ceeb yog txhua yam asbestos, xws li chrysotile, bluestone paj rwb, thiab lwm yam. Cov minerals fiber suav nrogtxhuas silicate fiber, iav fiber, gypsum fiber, carbon fiber, thiab lwm yam.
Cov cim qhia txog kev siv tshuab
1. qhov nruab nrab fiber ntev 1.0-3.5 hli
2. Qhov nruab nrab ntawm cov fiber 3.0-8.0 μ M
3. kev faib fiber 40 × 30 ~ 40% 60 × 40 ~ 60%
4. lub zog hlawv fiber (kho raws li cov neeg siv khoom xav tau) <1% (800 ℃ / h)
5. cov ntsiab lus pob slag <3%
6. cov dej noo ntawm cov fiber <1.5%
7. muaj peev xwm fiber 0.10-0.25g / cm3
8. cov khoom siv asbestos
1. Cov tshuaj resin tsawg/muaj peev xwm ntxiv tau ntau: vim tias txawm yog duab twg los xij, cov duab kheej kheej muaj qhov chaw me tshaj plaws thiab qhov xav tau cov tshuaj resin rau cov hlaws dai ntab kuj tsawg heev. Kev sib sau ua ke ntawm cov khoom me me kuj tau txhim kho. Qhov faib tawm ntawm cov khoom me me ntawm cov hlaws dai ntab tso cai rau cov microspheres me me kom sau qhov sib txawv ntawm cov microspheres loj dua. Qhov tshwm sim... yog qhov tseeb: cov tshuaj ntau, cov khoom khov siab, VOC qis dua, thiab cov tshuaj tsawg dua ntawm lwm cov khoom;
2. Cov viscosity qis/zoo dua qhov ntws: Tsis zoo li cov khoom me me uas tsis sib xws, cov hlaws dai uas ntab yooj yim dov ntawm ib leeg. Qhov no ua rau cov viscosity qis dua thiab zoo dua qhov ntws rau cov kab ke uas siv cov hlaws dai uas ntab. Ntxiv mus, qhov txau ntawm lub kab ke kuj tau zoo dua;
3. Kev Nyuaj Siab/Kev Hnav Tsis Taus: Cov hlaws dai drift yog cov microspheres muaj zog thiab tawv uas tuaj yeem txhim kho qhov nyuaj, kev ntxuav tau, thiab kev hnav tsis tau ntawm cov txheej txheej;
4. Cov nyhuv rwb thaiv tsev zoo heev: Vim yog cov qauv hollow spherical ntawm cov hlaws dai ntab, lawv muaj cov nyhuv rwb thaiv tsev zoo heev thaum sau rau hauv txheej;
5. Kev tswj qhov ci ntsa iab: Ua ib qho khoom sau, cov hlaws dai uas ntab tuaj yeem txo qhov ci ntsa iab thiab tswj qhov nce siab. Txawm tias nyob rau hauv cov xwm txheej uas muaj kev xav tau siab rau kev ntxiv, lawv tuaj yeem tshem tawm qhov nce ntxiv ntawm viscosity los ntawm cov neeg sawv cev matting ib txwm muaj, thiab tus nqi kuj qis;
6. Inertia: Cov hlaws dai drift yog tsim los ntawm cov khoom inert, yog li muaj kev ruaj khov zoo heev, tiv taus huab cua, tiv taus corrosion, thiab tiv taus tshuaj lom neeg;
7. Kev Pom Tsis Pom Kev: Lub duab kheej kheej ntawm lub hlaws ntab qeeb qeeb thiab tawg lub teeb, ua rau muaj kev nce ntxiv ntawm lub zog npog ntawm lub txheej;
8. Kev tawg ua tej daim me me: Cov hlaws dai uas tawg ua tej daim me me zoo li cov khoom siv hauv cov pob zeb. Vim lawv cov phab ntsa tuab thiab lub zog compressive siab, lawv tuaj yeem tiv taus kev ua cov khoom sib tov, cov tshuab extruder, thiab cov tshuab molding;
9. Kev ua qias tuaj ntawm cov silicon uas tsis yog crystalline: Tsis zoo li lwm cov khoom siv fillers, cov ntsiab lus ntawm cov silicon crystalline hauv cov hlaws dai uas ntab yog qis dua qib tsis muaj teeb meem. Hom hlaws dai uas ntab no tsis suav tias yog cov carcinogen thiab tsis xav tau cov cim ceeb toom tshwj xeeb los qhia nws.
10. Cov txheej txheem kev lag luam ruaj khov: viscosity qis, koob tshuaj ntau, txo VOC, txhim kho qhov nyuaj, tswj kev ci ntsa iab, ua kom tsis txhob hnav, txau tau yooj yim, thiab txo tus nqi;
11. Cov txheej txheem sab saum toj rau kev lag luam uas yaj tau hauv dej: ua kom cov khoom khov kho, txo cov permeability ntawm zaj duab xis, txhim kho kev tiv thaiv corrosion, hardness, inertness, hnav tsis kam, tswj kev ci ntsa iab, thiab txo cov nqi;
12. Kev rwb thaiv cua sov, kev rwb thaiv tsev, thiab cov txheej tiv taus hluav taws: Tiv taus kub heev, tiv taus hluav taws, thiab ua kom rwb thaiv tsev zoo heev;
13 Cov Txheej Txheem Txij Nkawm: Kev tiv thaiv tshuaj lom neeg thiab kev xeb, kev ruaj khov, kev hnav tsis kam, kev nkag mus rau hauv txheej txheej tsawg,
