Kugwiritsa ntchito Vermiculite
Paulimi, vermiculite itha kugwiritsidwa ntchito ngati chinyontho cha nthaka, chifukwa cha kusinthana kwa cation ndi kupopera, kusintha malo, kusungidwa kwa madzi ndi chinyezi, kukulitsa kuperewera kwa nthaka ndi madzi, kusintha nthaka yachilengedwe; vermiculite imathandizanso kuthyolako gawo, kuletsa kusintha kwa mtengo wa PH, kupangitsa feteleza kutulutsa pang'onopang'ono pakukula kwazomera, ndikuloleza kugwiritsa ntchito feteleza pang'ono chomera koma sikuvulaza. Vermiculite itha kuperekedwanso ku mbewu yomwe ili ndi K, Mg, Ca, Fe, ndi kufufuza zinthu za Cu, Zu. Monga mayamwidwe, kusinthanitsa kwa cation ndi kapangidwe kazinthu zama mankhwala ena a vermiculite, kotero imasewera kukonza kukonza feteleza, kusunga madzi, kusungirako madzi, kupatsa mphamvu ndi feteleza wa mchere, ndi maudindo ena angapo. Mayesowa adawonetsa: ikani 0.5-1% yowonjezera vermiculite yosakanizidwa ndi manyowa, ithetsani zokolola ndi 15-20%.
Posamalira maluwa, vermiculite itha kugwiritsidwa ntchito ngati maluwa, ndiwo zamasamba, kulima zipatso, kuswana ndi zina, kuwonjezera pakuwumba dothi ndi zowongolera, komanso pachikhalidwe chopanda dothi. Kukhala mizu yodyetsa bwino pobzala mitengo yowotchera ndi kubzala mitengo, ndibwino kuyika mbewu ndi kutumiza mbewu. Vermiculite ikhoza kulimbikitsa kukula kwa mizu ya mbewu ndi kukula kwa nthangala, imatha kupereka madzi ndi chakudya cha mbewu zomwe zikukula kwa nthawi yayitali, ndikuti mizu ikhale yolimba. Vermiculite imatha kupangitsa mbewuyo kukhala ndi madzi ndi mchere wokwanira koyambira, kulimbikitsa mbewuzo kuti zikule msanga, ndikuwonjezera zokolola.
Vermiculite yowonjezeredwa, yomwe imayatsidwa padenga, idzasewera kwambiri kutentha pamatenthedwe, ndikupangitsa nyumbayo kukhala yotentha nthawi yachisanu komanso yozizira. Kugwiritsa ntchito njerwa za vermiculite kukhoma kwa magawo okwera kwambiri kapena kugwiritsa ntchito zotchinga za vermiculite monga zida zogwirizira m'mahotela kapena malo osangalatsa, zotsatira za kuyamwa, umboni wamoto, kusungidwa kwa kutentha ndi zina zotero ziziwonekera kwathunthu ndipo nyumbayo idzachepetsedwa katundu wake .
Malo okhala ndi mpweya wochepa thupi utatha kukula kwa vermiculite, zomwe zimapangitsa kuti vermiculite yowonjezereka ikhale chimbale cha mawu omveka. Pamene pafupipafupi ndi 2000C / S, gawo lokhazikika la 5mm thick vermiculite ndi 63%, 6mm 84% ndi 8mm 90%.
Vermiculite ndi yabwino kwambiri kukaniza chisanu monga momwe mphamvu ndi mphamvu zake zimasungidwira ngakhale zitadutsa nthawi 40 ya kuyesa-thaw kuzungulira kwa -20 ℃. Ndizowoneka bwino komanso ndili ndi malo okhala. Imatha kusunga kutentha komanso kupewa kuteteza. Kupatula apo, imatha kuyamwa ma radiation, chifukwa chake mabatani a vermiculite amatha kuyikidwa mkati mwa labotale kuti alowe m'malo okwera 90% amiyala yobalalika. 65mm wandiweyani vermiculite ndi wofanana ndi 1mm wandiweyani wakotsogolera.
Vermiculite ufa wopitilira unapangidwa ndi vermiculite ore, wama calcor pamoto wambiri, kuwunika, kupera. Zomwe zikudziwika ndi izi: 3-8mm, 1-3mm, 10-20mesh, 20-40mesh, 40-60mesh, 60mesh, 200mesh, 325mesh, 1250mesh. Kuyika: zida zowonjezera nyumba, chipangizo chosungiramo nyumba, chowongolera magalimoto, chitoliro chowongolera, chosungira komanso chosungira, chosungira mafuta osungira mafuta, makwerero achitsulo, simenti yozimitsa moto, zida zamagetsi zamagalimoto, zida zowumbitsira ndege, zida zosungira yozizira, basi zida zowotchera zinthu, mipando yoziziritsa ya pachipala cha wallboard, zopangira zitsulo, zozimitsira moto, zosefera, kusungiramo kuzizira, linoleum, mapanelo okumba, ma cornices, mapepala amiyala yamiyala, kusindikiza kwa pepala, kutsatsa kunja, utoto, kuonjezera mawonekedwe a penti, zithunzi zofewa zamatabwa pepala lamoto wamatabwa, inki wagolide ndi mkuwa, penti zowonjezera zakunja.
