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.
