Msuzi wa vermiculite

Kufotokozera mwachidule:

Vermiculite ndi mchere wa silicate, womwe ndi gawo laling'ono la mica.Mankhwala ake akuluakulu: 22MgO · 5Al2O3 · Fe2O3 · 22SiO2 · 40H2O Theoretical molecular formula pambuyo pakuwotcha ndi kufalikira: ( OH) 2 (MgFe) 2 · (SiAlFe) 4O104H2O

Ore ore vermiculite ndi mawonekedwe osanjikiza okhala ndi madzi pang'ono pakati pa zigawo.Pambuyo pakuwotcha pa 900-950 ℃, imatha kutaya madzi m'thupi, kuphulika ndikukulitsidwa mpaka 4-15 nthawi ya voliyumu yoyambirira, kupanga porous thupi zakuthupi.Ili ndi kutsekemera kwamafuta, kukana kutentha kwambiri, kutchinjiriza, antifreeze, kukana zivomezi, kukana kwa dzimbiri kwa asidi ndi alkali, kutchinjiriza kwamawu ndi zina.

Kugwiritsa ntchito vermiculite

Amagwiritsidwa ntchito poteteza kutentha

Vermiculite yowonjezera imakhala ndi mawonekedwe a porous, kulemera kochepa komanso malo osungunuka kwambiri, ndipo ndi yabwino kwambiri pazitsulo zotentha kwambiri (pansi pa 1000 ℃) ndi zipangizo zotetezera moto.Gulu la simenti la vermiculite la masentimita khumi ndi asanu lidawotchedwa pa 1000 ℃ kwa maola 4-5, ndipo kutentha kumbuyo kunali pafupifupi 40 ℃.Silabu ya vermiculite ya masentimita asanu ndi awiri inawotchedwa pa kutentha kwa 3000 ℃ kwa mphindi zisanu ndi ukonde wamoto woyaka moto.Mbali yakutsogolo inasungunuka, ndipo kumbuyo kunalibe kutentha ndi manja.Chifukwa chake imaposa zida zonse zotsekera.Monga zinthu za asbestosi ndi diatomite.
Vermiculite ingagwiritsidwe ntchito ngati zida zopangira matenthedwe m'malo otentha kwambiri, monga njerwa zotenthetsera matenthedwe, matabwa opaka mafuta ndi zipewa zosungunulira zotentha m'makampani osungunula.Zida zilizonse zomwe zimafuna kutsekemera kwamafuta zimatha kutsekedwa ndi ufa wa vermiculite, zinthu za simenti za vermiculite (njerwa za vermiculite, mbale za vermiculite, mapaipi a vermiculite, etc.) kapena mankhwala a asphalt vermiculite.Monga makoma, madenga, zosungiramo zozizira, ma boilers, mapaipi a nthunzi, mapaipi amadzimadzi, nsanja zamadzi, ng'anjo zosinthira, zosinthira kutentha, kusungirako zinthu zoopsa, ndi zina zambiri.

Amagwiritsidwa ntchito ngati kusanjikiza kwa mawu

Vermiculite kukod chifukwa cha mapangidwe abwino mpweya kusiyana wosanjikiza, kupanga porous kutchinjiriza zakuthupi, pamene pafupipafupi 2000C / S , vermiculite makulidwe 5mm pamene phokoso mayamwidwe mlingo wa 63% , makulidwe a vermiculite 6mm pamene phokoso kutengeka mlingo wa 84 % , vermiculite Kuthamanga kwa phokoso ndi 90% pamene makulidwe a miyala ndi 8mm.

Kwa zida zoteteza ma radiation

Vermiculite imatha kuyamwa ma radiation.Mbale ya vermiculite yomwe imayikidwa mu labotale imatha kulowa m'malo otsogolera okwera mtengo kuti amwe ma radiation amwazikana ndi 90%.Makulidwe a vermiculite ndi 65mm, omwe ndi ofanana ndi mbale yotsogolera ya 1mm.

Kwa kulima mbewu

Chifukwa ufa wa vermiculite umakhala ndi mayamwidwe abwino amadzi, kutulutsa mpweya, kutsekemera, kumasuka, kusaumitsa ndi zina, ndipo ndi wosabala komanso wopanda poizoni pambuyo pakuwotcha kutentha kwambiri, komwe kumathandizira kuzuka ndi kukula kwa mbewu.Itha kugwiritsidwa ntchito kubzala, kukweza mbande ndi kudula maluwa ndi mitengo yamtengo wapatali, masamba, mitengo yazipatso ndi mphesa, komanso kupanga feteleza wamaluwa ndi nthaka yazakudya.

Kupanga zokutira mankhwala

Vermiculite yokhala ndi kukana dzimbiri kwa asidi, 5% kapena kuchepera kwa sulfuric acid, hydrochloric acid, acetic acid, 5% aqueous ammonia, sodium carbonate, anti-corrosive effect.Chifukwa cha kulemera kwake kopepuka, kumasuka, kusalala, chiŵerengero chachikulu cha m'mimba mwake ndi makulidwe, kumatira mwamphamvu, ndi kukana kutentha kwakukulu, itha kugwiritsidwanso ntchito ngati zodzaza popanga utoto (penti zosayaka, utoto woletsa kukwiya, utoto wosalowa madzi. ) kuteteza utoto Kukhazikitsa ndi kutumiza magwiridwe antchito.

Kwa zinthu zokangana

Vermiculite yowonjezera imakhala ndi mawonekedwe a pepala komanso kutentha kwa kutentha, imatha kugwiritsidwa ntchito popanga zinthu zokangana ndi zida zomangira, ndipo imakhala ndi ntchito yabwino kwambiri, yopanda poizoni komanso yopanda vuto, ndipo ndi chinthu chatsopano choteteza chilengedwe pakuipitsa chilengedwe.
