Fiber-yada inta badan ka kooban macdanta sepiolite waxaa loo yaqaannaa fiilooyinka macdanta sepiolite.sepiolite waa macdanta macdanta silicate ee hodanka ku ah magnesium oo leh qaacido physicochemical ah Mgo [Si12O30] (OH) 4 12 H2O.Afar unug oo biyo ah waa biyo crystalline ah, inta soo hartayna waa biyo zeolite ah, waxaana inta badan ku jira xaddi yar oo curiye ah sida manganese iyo chromium.

Sepiolite waxay leedahay adsorption wanaagsan, midabaynta, xasilloonida kulaylka, caabbinta daxalka, iska caabinta shucaaca, dahaarka kulaylka, iska caabinta iska caabinta, iyo caabbinta dhexgalka, waxaana si weyn loogu isticmaalaa qodista, batroolka, daawada, wax soo saarka, qalabka dhismaha, sunta cayayaanka, bacriminta, alaabada caagga ah, braking. , iyo goobo kale.

Shuruudaha loogu talagalay fiilooyinka macdanta sepiolite ee meelaha qaarkood waa sida soo socota:

Heerka midabaynta waa ≥ 100%, heerka garaaciddu waa>4m3/t, kala firdhisyaduna waa dhakhso, saddex jeer ka badan asbestos.Meesha dhalaalidu waa 1650 ℃, viskosity-ku waa 30-40s, si dabiici ah ayuu u qudhmi karaa iyada oo aan la soo saarin wasakh.Waa qodobka labaad ee qorshaha xorta ah ee asbestos-ka ee qaranku si weyn ugu ololeeyay, kaas oo si buuxda looga hirgeliyay dalka dibadiisa loona yaqaan fiber macdanta cagaaran.

faa'iido

1. Isticmaalka sepiolite sida badeeco caag ah waa mid wasakh la'aan ah, oo leh wax-qabad aad u wanaagsan iyo iska caabbinta aashitada oo sarreeya.

2. Ku walaaqida sepiolite waxay keentaa todoba jeer in ka badan midabka dareeraha iyo nadiifinta marka loo eego asbestos.

3. Isticmaalka sepiolite ee khilaafku waxay leedahay barti wanaagsan, kala firdhisanaan adag, iyo nuugista codka 150 jeer ka asbestos-ka.Dhawaqa is jiid jiidku aad buu u hooseeyaa, waana alaab cayriin ah oo qiimaheedu sarreeyo oo lagu kordhiyo dakhliga dhoofinta.

Fiber sepiolite waa fiber macdanta dabiiciga ah, taas oo ah kala duwanaansho fibrous ah macdanta sepiolite waxaana loo yaqaan α- Sepiolite.Sida laga soo xigtay khubarada, sepiolite, sida macdanta silicate silsilad lakabka, waxay leedahay 2: 1 unug dhismeed oo lakab ah oo ka kooban laba lakab oo ah tetrahedra silikoon oxygen sandwich by lakabka magnesium oxygen octahedra.Lakabka tetrahedral waa mid joogto ah, iyo jihaynta noocyada ogsijiinta falcelinta ee lakabka ayaa mar mar dib u noqosho xilliyeed ah.Lakabyada octahedral waxay sameeyaan kanaalo si kala duwan u habaysan oo u dhexeeya lakabyada sare iyo hoose.Jihaynta kanaalka ayaa la jaan qaadaya dhidibka fiber-ka, taas oo u oggolaanaysa unugyada biyaha, cations biraha, molecules yaryar ee organic, iwm.Sepiolite waxay leedahay caabbinta kulaylka wanaagsan, ion beddelka iyo sifooyinka kicinta, iyo sidoo kale sifooyin aad u fiican sida caabbinta daxalka, caabbinta shucaaca, dahaarka, iyo kuleylka kuleylka.Gaar ahaan, Si-OH ee qaab-dhismeedkeeda waxay si toos ah uga falcelin kartaa walxaha dabiiciga ah si ay u abuurto macdanta dabiiciga ah.

Qaybteeda qaabdhismeedkeeda, tetrahedra silicon oxide iyo magnesium oxide octahedra way is beddelaan, iyagoo muujinaya sifooyinka kala-guurka ee lakabyada iyo silsiladaha sida qaab-dhismeedka.Sepiolite waxay leedahay sifooyin gaar ah oo jireed iyo kiimiko, oo leh meel sare oo gaar ah (ilaa 800-900m/g), borosity weyn, iyo adsorption xoog leh iyo awoodaha kicinta.

Goobaha codsiga ee sepiolite sidoo kale waa kuwo aad u ballaaran, ka dib markii daaweyn taxane ah sida nadiifinta, farsamaynta ultra-fine, iyo wax ka beddelka, sepiolite waxaa loo isticmaali karaa adsorbent, wakiilka nadiifinta, deodorant, wakiilka xoojinta, wakiilka ganaaxa, wakiilka thixotropic, Wakiilka buuxinta, iwm ee dhinacyada warshadaha sida daaweynta biyaha, catalysis, caag, dahaarka, bacriminta, quudinta, iwm. Intaa waxaa dheer, caabbinta milixda wanaagsan iyo iska caabinta heerkulka sare ee sepiolite waxay ka dhigaysaa wax tayo sare leh oo dhoobo ah oo loo isticmaalo batroolka. qodista, qoditaanka geothermal, iyo goobo kale.
