Ukusetyenziswa kwevermiculite
Isetyenziselwa ukufakwa kwe-thermal
I-vermiculite eyandisiweyo ineempawu zokuba yi-porous, ubunzima obulula kunye neqondo eliphezulu lokunyibilika, kwaye ifaneleke kakhulu kwizinto zokushisa eziphezulu zokushisa (ngaphantsi kwe-1000 ℃) kunye nezixhobo zokugquma umlilo.Ibhodi yevermiculite yesamente eneshumi elinesihlanu yecentimeter-thick yatshiswa kwi-1000 ℃ ngeeyure ezi-4-5, kwaye ubushushu ngasemva babumalunga nama-40 ℃ kuphela.I-slab ye-vermiculite yeesentimitha ezisixhenxe yatshiswa kubushushu obuphezulu obuyi-3000 ℃ imizuzu emihlanu ngumnatha odityaniswe nedangatye.Icala elingaphambili lanyibilika, kwaye umva wawungekafudumala ngesandla.Ngoko iyodlula zonke izinto zokugquma.Njengeemveliso zeasbestos kunye nediatomite.
I-Vermiculite ingasetyenziselwa njengezinto zokufakelwa kwe-thermal kwiindawo eziphakamileyo zokushisa, njengezitena zokufakelwa kwe-thermal, iibhodi ze-thermal insulation caps kwi-smelting industry.Nasiphi na isixhobo esifuna ukugqunywa kwe-thermal sinokufakwa kwi-vermiculite powder, iimveliso ze-sement vermiculite (izitena ze-vermiculite, iipleyiti ze-vermiculite, imibhobho ye-vermiculite, njl.) okanye iimveliso ze-asphalt vermiculite.Ezinje ngeendonga, uphahla, iindawo zokugcina ezibandayo, iibhoyila, imibhobho yomphunga, imibhobho yolwelo, iinqaba zamanzi, iziko lokuguqulela, abatshintshisi bobushushu, ukugcinwa kwempahla eyingozi, njl.njl.
Isetyenziselwa ukugquma isandi
I-Vermiculite eyandisiweyo ngenxa yokubunjwa kwe-gap ecolekileyo yomoya, yenza i-porous insulation material, xa ukuphindaphinda kwe-2000C / S, ubukhulu be-vermiculite 5mm xa isantya sokufunxa isandi se-63%, ubukhulu be-vermiculite 6mm xa isantya sokufunxa isandi se-84 % , vermiculite Izinga lokufunxa isandi yi-90% xa ubukhulu bamatye buyi-8mm.
Kumaziko okhuselo lwemitha
I-Vermiculite inokufunxa i-radiation.Ipleyiti yevermiculite efakwe kwilabhoratri inokutshintsha ipleyiti yelothe enexabiso eliphezulu ukuze ifunxe imitha esasazekileyo ngama-90%.Ubukhulu be-vermiculite yi-65mm, elingana ne-1mm yepleyiti yokukhokela.
Ukulinywa kwezityalo
Ngenxa yokuba i-vermiculite powder inokufunxeka kakuhle kwamanzi, i-air permeability, i-adsorption, i-looseness, i-non-harder kunye nezinye iipropati, kwaye ayinyumba kwaye ayinayo ityhefu emva kokutshiswa kobushushu obuphezulu, obukhuthaza ukuhluma kunye nokukhula kwezityalo.Ingasetyenziselwa ukutyala, ukukhulisa izithole kunye nokusika iintyatyambo nemithi exabisekileyo, imifuno, imithi yeziqhamo kunye neediliya, kwakunye nokwenza isichumiso seentyatyambo nomhlaba onesondlo.
Ukwenziwa kokufakwa kweekhemikhali
I-Vermiculite ene-corrosion resistance to acid, ye-5% okanye ngaphantsi kwe-sulfuric acid, i-hydrochloric acid, i-acetic acid, i-5% ye-ammonia enamanzi, i-sodium carbonate, i-anti-corrosive effect.Ngenxa yobunzima bayo obulula, ukuxenga, ukuguda, umlinganiselo omkhulu wediameter-to-thickness ratio, ukuncamathela okuqinileyo, kunye nokumelana nobushushu obuphezulu, isenokusetyenziswa njengesithambiso xa kusenziwa iipeyinti (ipeyinti ezingatshiyo, iipeyinti ezichasayo, ipeyinti engenamanzi. ) ukuthintela ipeyinti Ukumisa kunye nokuthumela ukusebenza kwemveliso.
Ngezixhobo zokukhuhlana
I-vermiculite eyandisiweyo ine-sheet-like and thermal insulation properties, ingasetyenziselwa imathiriyeli yokukhuhlana kunye nezinto zokuqhobosha, kwaye inomsebenzi ogqwesileyo, ayinayo ityhefu kwaye ayinabungozi, kwaye iyimathiriyeli entsha ehambelana nokusingqongileyo kungcoliseko lokusingqongileyo.
