Sepiolite fiber ntau yog ib yam ntawm cov ntxhia hauv ntuj fiber ntau, uas yog fiber ntau ntawm sepiolite ntxhia, hu ua α - sepiolite.Sepiolite yog ib hom txheej txheej saw silicate ntxhia.Nyob rau hauv cov qauv ntawm sepiolite, ib txheej ntawm magnesia octahedron yog sandwiched ntawm ob silicon oxygen tetrahedrons, tsim ib tug 2: 1 hom txheej txheej chav tsev.Cov txheej tetrahedral yog txuas mus ntxiv thiab cov kev taw qhia ntawm cov pa oxygen nquag hauv txheej yog thim rov qab ib ntus.Cov txheej octahedral tsim ib txoj kab sib txuas ntawm cov txheej sab saud thiab qis.Txoj kev taw qhia channel yog ua raws li cov axis fiber ntau, tso cai rau dej molecules, hlau cations, organic me me molecules thiab thiaj li nyob rau hauv.Sepiolite muaj cov cua sov zoo.Sepiolite kuj muaj cov ion pauv zoo thiab cov khoom catalytic, nrog rau kev tiv thaiv corrosion, hluav taws xob tiv thaiv, rwb thaiv tsev, rwb thaiv tsev kub thiab lwm yam khoom zoo, tshwj xeeb tshaj yog Si Oh hauv nws cov qauv tuaj yeem cuam tshuam ncaj qha nrog cov organic los tsim cov organic ntxhia derivatives.
Sepiolite kuj tau siv dav hauv kev ua kom huv, kev ua haujlwm zoo thiab kev hloov kho.Sepiolite tuaj yeem siv los 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 ntsev zoo thiab kub tsis kam, yog li nws tuaj yeem siv los ua cov khoom siv zoo drilling av hauv cov roj drilling, geothermal drilling thiab lwm yam.
Sepiolite fiber belongs rau cov ntxhia fiber ntau, uas tau txais los ntawm cov pob zeb hauv pob zeb.Nws cov khoom tseem ceeb yog ntau yam oxides, xws li silica, alumina, magnesium oxide, thiab lwm yam. nws cov ntsiab lus tseem ceeb yog txhua yam asbestos, xws li chrysotile, bluestone paj rwb, thiab lwm yam mineral fiber ntau suav nrog.aluminium silicate fiber, iav fiber, gypsum fiber, carbon fiber, thiab lwm yam.

1. Tsawg resin ntau npaum li cas / siab muaj peev xwm ntxiv: vim tias nyob rau hauv ib qho duab, cov duab kheej kheej muaj qhov tsawg tshaj plaws ntawm thaj chaw tshwj xeeb thiab qhov kev thov rau resin rau cov hlaws ntab kuj yog tsawg.Cov tsub zuj zuj ntawm cov khoom kuj tau txhim kho.Qhov dav particle loj faib ntawm cov hlaws ntab tso cai rau me me microspheres los sau qhov khoob ntawm cov microspheres loj.Qhov tshwm sim ... yog qhov tseeb: ntau npaum li cas, cov ntsiab lus siab, VOC qis dua, thiab txo qhov ntau npaum li cas ntawm lwm cov khoom;
2. Tsawg viscosity / txhim kho flowability: Tsis zoo li cov khoom tsis sib xws, cov hlaws ntab ntab yog yooj yim rau yob ntawm ib leeg.Qhov no ua rau qis viscosity thiab zoo flowability rau cov tshuab siv cov hlaws ntab ntab.Ntxiv mus, lub sprayability ntawm lub system kuj tau txhim kho;
3. Hardness / Wear Resistance: Drift hlaws yog cov muaj zog thiab tawv microspheres uas tuaj yeem txhim kho cov tawv tawv, ntxuav, thiab hnav tsis kam ntawm cov txheej;
4. Cov nyhuv rwb thaiv tsev zoo: Vim lub hollow spherical qauv ntawm cov hlaws dai, lawv muaj cov nyhuv rwb thaiv tsev zoo heev thaum sau rau hauv txheej;
5. Gloss tswj: Raws li ib tug muab tub lim, floating hlaws yuav txo tau gloss thiab tswj surges.Txawm tias nyob rau hauv cov xwm txheej uas yuav tsum tau siab ntxiv, lawv muaj peev xwm tshem tawm qhov tseem ceeb ntawm cov viscosity tshwm sim los ntawm cov neeg sawv cev matting zoo tib yam, thiab tus nqi kuj tsawg;
6. Inertia: Drift hlaws dai yog tsim los ntawm inert Cheebtsam, yog li muaj zoo heev durability, huab cua tsis kam, corrosion kuj, thiab tshuaj tiv thaiv;
7. Opacity: Lub hollow spherical zoo ntawm lub floating hlaws slows down thiab scatters lub teeb, ua rau ib tug nce nyob rau hauv lub zog ntawm lub txheej txheej;
8. Dispersibility: Drift hlaws dai yog dispersed zoo li cov pob zeb hauv av fillers.Vim lawv cov phab ntsa tuab thiab muaj zog compressive siab, lawv tuaj yeem tiv taus kev ua haujlwm ntawm txhua hom mixers, extruders, thiab molding tshuab;
9. Tsis yog crystalline silicon muaj kuab paug: Tsis zoo li lwm cov fillers, cov ntsiab lus ntawm crystalline silicon hauv cov hlaws ntab ntab yog qis dua qib tsis muaj teeb meem.Hom hlaws ntab no tsis suav tias yog cov kab mob carcinogen thiab tsis tas yuav muaj cov cim ceeb toom tshwj xeeb los qhia nws.
10. Cov khoom siv ua haujlwm siab: tsis muaj viscosity, siab npaum li cas, txo VOC, txhim kho hardness, tswj gloss, nce hnav tsis kam, sprayability, thiab txo nqi;
11. Dej soluble industrial topcoat: nce cov ntsiab lus, txo cov yeeb yaj kiab permeability, txhim kho corrosion kuj, hardness, inertness, hnav tsis kam, tswj gloss, thiab txo cov nqi;
12. Thermal rwb thaiv tsev, rwb thaiv tsev, thiab fireproof coatings: kub tsis kam, nplaim retardancy, thiab zoo heev rwb thaiv tsev nyhuv;
13 Kev Kho Cov Txheej Txheem: Tshuaj thiab corrosion kuj, durability, hnav tsis kam, tsis tshua muaj txheej permeability,
