Isticmaalka vermiculite
Loo isticmaalo dahaarka kulaylka
Vermiculite balaartay waxay leedahay sifooyin daloola, miisaan fudud iyo barta dhalaalka sare, waxayna aad ugu habboon tahay qalabka dahaadhka heerkulkiisu sarreeyo (ka hooseeya 1000 ℃) iyo agabka dahaadhka dab-demiska.Looxa vermiculite cement dhumucdiisuna tahay shan iyo toban sentimitir ayaa lagu gubay 1000 ℃ 4-5 saacadood, heerkulka dhabarkuna wuxuu ahaa kaliya 40 ℃.Daboolka qaro weyn oo todoba sentimitir ah ayaa ku gubtay heerkul sare oo ah 3000 ℃ shan daqiiqo kadib markii shabag ololka alxanka lagu sameeyay.Dhankii hore ayaa dhalaalay, dhabarkuna wali gacanta kuma diirin.Markaa waxay ka sarraysaa dhammaan agabka dahaarka.Sida asbestos iyo alaabta diatomite.
Vermiculite waxa loo isticmaali karaa sida agabka dahaadhka kulaylka ee tas-hiilaadka heerkulku sarreeyo, sida lebenka kuleylka kuleylka, looxyada kuleylka kuleylka iyo koofiyadaha kuleylka kuleylka ee warshadaha dhalaalidda.Qalab kasta oo u baahan kuleylka kuleylka waxaa lagu dahaaran karaa budada vermiculite, alaabta cement vermiculite (lebenka vermiculite, taarikada vermiculite, tuubooyinka vermiculite, iwm) ama alaabta vermiculite asphalt.Sida darbiyada, saqafyada, kaydinta qaboojiyaha, kululeeyaha, tuubooyinka uumiga, tuubooyinka dareeraha ah, munaaradaha biyaha, foornooyinka beddelka, kulaylka beddelka, kaydinta alaabta khatarta ah, iwm.
Loo isticmaalo lakabka dahaarka dhawaaqa
Vermiculite balaariyay sababtoo ah samaynta lakabka farqiga hawo wanaagsan, samaynta walax dahaarka ah, marka inta jeer ee 2000C / S , vermiculite dhumucdiisuna 5mm marka heerka nuugista dhawaaqa 63% , dhumucdiisuna of vermiculite 6mm marka heerka nuugista codka ee 84 % , vermiculite Heerka nuugista codka waa 90% marka dhumucda dhagaxu tahay 8mm.
Qalabka ilaalinta shucaaca
Vermiculite waxay nuugi kartaa shucaaca.Saxanka vermiculite ee lagu rakibay shaybaarka wuxuu bedeli karaa saxanka rasaasta ee qiimaha sare leh si uu u nuugo shucaaca kala firidhsan 90% .Dhumucda vermiculite waa 65mm, taas oo u dhiganta 1mm saxan rasaas ah.
Wixii beerashada dhirta
Sababtoo ah budada vermiculite waxay leedahay nuugista biyaha wanaagsan, hawada hawada, adsorption, dabacsanaan, qallafsanaan la'aan iyo waxyaabo kale, waana nadiif ah oo aan sun ahayn ka dib marka la dubayo heerkul sare, taas oo ku habboon xididada iyo koritaanka dhirta.Waxa loo isticmaali karaa beerista, beerista iyo jarista ubaxa iyo geedaha qaaliga ah, khudaarta, geedaha miraha iyo canabka, iyo sidoo kale samaynta bacriminta ubaxa iyo carrada nafaqeynta.
Wax soo saarka ee daahan kiimikaad
Vermiculite oo leh caabbinta daxalka ee aashitada, oo ah 5% ama ka yar sulfuric acid, hydrochloric acid, acetic acid, 5% ammonia aqueous, sodium carbonate, saamaynta anti-daxalka.Sababtoo ah culeyskiisa fudud, dabacsanaantiisa, jilicsanaanta, dhexroorka iyo dhumucda weyn, dhejinta xooggan, iyo iska caabinta heerkulka sare, waxaa sidoo kale loo isticmaali karaa buuxinta rinjiyada (rinjiyada dabka celinaya, rinjiga ka hortagga xanaaqa, rinjiyada biyuhu ) si looga hortago dejinta rinjiga iyo diritaanka waxqabadka alaabta.
Qalabka isku dhaca
Vermiculite fidsan waxay leedahay sifooyin dahaar u eg xaashida iyo kulaylka, waxaa loo isticmaali karaa maaddooyinka isku dhufashada iyo qalabka biriiga, waxayna leedahay wax qabad aad u wanaagsan, aan sun ahayn oo aan dhib lahayn, waana shay cusub oo deegaanka u wanaagsan wasakhowga deegaanka.
