Cov fibers feem ntau yog ua los ntawm cov zaub mov sepiolite hu ua sepiolite mineral fibers. sepiolite yog cov zaub mov fiber ntau magnesium nrog cov mis physicochemical ntawm Mgo [Si12O30] (OH) 4 12 H2O. Plaub lub molecule dej yog dej crystalline, tus so yog dej zeolite, thiab feem ntau muaj cov ntsiab lus me me xws li manganese thiab chromium.

Sepiolite muaj kev nqus tau zoo, tshem tawm xim, thermal stability, corrosion resistance, radiation resistance, thermal insulation, kev sib txhuam tsis kam, thiab kev nkag mus tsis kam, thiab yog siv dav hauv kev khawb, roj av, tshuaj, brewing, cov ntaub ntawv tsim kho, tshuaj tua kab, chiv, roj hmab, nres, thiab lwm yam teb.

Cov kev cai rau cov sepiolite mineral fibers hauv qee qhov chaw yog raws li nram no:

Tus nqi decolorization yog ≥ 100%, tus nqi pulping yog> 4m3 / t, thiab dispersibility yog ceev, peb zaug ntawm asbestos. Lub melting point yog 1650 ℃, lub viscosity yog 30-40s, thiab nws tuaj yeem decompose ntuj yam tsis muaj kev ua qias tuaj. Nws yog qhov thib ob ntawm lub teb chaws txoj kev npaj tsis muaj asbestos, uas tau siv tag nrho txawv teb chaws thiab hu ua ntsuab mineral fiber.

qhov zoo dua

1. Siv sepiolite ua cov khoom siv roj hmab tsis muaj kuab paug, nrog kev ua haujlwm zoo heev thiab tiv taus kua qaub ntau dua.

2. Kev siv sepiolite ua kom cov kua dej tsis muaj xim thiab ua kom huv si ntau dua xya npaug dua li asbestos.

3. Kev siv sepiolite los ua kev sib txhuam muaj qhov elasticity zoo, qhov nyuaj dispersion ruaj khov, thiab qhov nqus suab tau 150 npaug ntawm asbestos. Lub suab sib txhuam qis heev, thiab nws yog cov khoom siv raw muaj nqis ntxiv rau kev khwv tau los ntawm kev xa tawm.

Sepiolite fiber yog ib hom fiber ntuj, uas yog ib hom fibrous ntawm sepiolite mineral thiab hu ua α-Sepiolite. Raws li cov kws tshaj lij, sepiolite, ua ib txheej silicate mineral, muaj ib txheej 2: 1 txheej uas muaj ob txheej ntawm silicon oxygen tetrahedra sandwiched los ntawm ib txheej ntawm magnesium oxygen octahedra. Txheej tetrahedral yog tas mus li, thiab kev taw qhia ntawm cov reactive oxygen hom hauv txheej dhau los ntawm kev hloov pauv tas li. Cov txheej octahedral tsim cov channel teeb tsa hloov pauv ntawm cov txheej sab saud thiab qis. Kev taw qhia ntawm cov channel 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 rau hauv nws. Sepiolite muaj kev tiv thaiv cua sov zoo, kev pauv ion thiab catalytic zog, nrog rau cov khoom zoo heev xws li kev tiv thaiv corrosion, kev tiv thaiv hluav taws xob, rwb thaiv tsev, thiab rwb thaiv tsev thermal. Tshwj xeeb, Si-OH hauv nws cov qauv tuaj yeem ncaj qha cuam tshuam nrog cov organic teeb meem los tsim cov organic mineral derivatives.

Hauv nws cov qauv, silicon oxide tetrahedra thiab magnesium oxide octahedra hloov pauv nrog ib leeg, qhia txog cov yam ntxwv hloov pauv ntawm cov txheej thiab cov saw zoo li cov qauv. Sepiolite muaj cov khoom siv lub cev thiab tshuaj lom neeg tshwj xeeb, nrog rau thaj chaw tshwj xeeb (txog li 800-900m2 / g), porosity loj, thiab muaj zog adsorption thiab catalytic peev xwm.

Cov teb siv ntawm sepiolite kuj dav heev, thiab tom qab ntau yam kev kho mob xws li kev ntxuav, kev ua tiav zoo heev, thiab kev hloov kho, sepiolite tuaj yeem siv ua adsorbent, purifying agent, deodorant, reinforcing agent, suspension agent, thixotropic agent, filling agent, thiab lwm yam hauv kev lag luam xws li kev kho dej, catalysis, roj hmab, coatings, chiv, pub, thiab lwm yam. Tsis tas li ntawd, qhov zoo tiv taus ntsev thiab kub tiv taus ntawm sepiolite ua rau nws yog cov khoom siv av nkos zoo siv hauv kev khawb roj av, geothermal drilling, thiab lwm yam teb.
