Kaalmada shaandhada dhulka Diatomaceous/Diatomaceous earth
CAS #: 61790-53-2 (budo calcined)
CAS #: 68855-54-9 (budada calcined la isku daray)
Isticmaalka: Waxaa loo isticmaalaa warshadaha wax soo saarka, warshadaha cabitaanka, warshadaha dawooyinka, sifaynta, sifaynta sonkorta, iyo warshadaha kiimikada.
Halabuurka kiimikada
Halabuurka kiimikaad ee dhulka diatomaceous inta badan waa SiO amorphous ah2, kaas oo u jira qaabka SiO2• nH2O. SiO2sida caadiga ah waxay ka badan tahay 80%, ilaa 94%. Waxa ku jira xaddi yar oo Al2O3, Fe2O3, CaO, MgO, K2O, na2O, P2O5, iyo walxaha organic, iyo sidoo kale qaar ka mid ah wasakhda biraha sida Cr iyo Ba. Halabuurka iyo waxa ku jira miinada dhulka diatomaceous way ku kala duwan yihiin gobollo kala duwan.
Guryaha Jirka
Dhulka Diatomaceous wuxuu leeyahay midabyo ay ka mid yihiin caddaan, cawl cad, cawl, cawl fudud, bunni khafiif ah, huruud khafiif ah, iwm.; Cufnaanta: 1.9 ~ 2.3g/cm3Cufnaanta bulk 0.34 ~ 0.65g/cm3; Barta dhalaalka: 1650 ℃ ~ 1750 ℃; Baaxadda gaarka ah ee 19-65cm2/g; Mugga daloolka 0.45 ~ 0.98cm3/g; Heerka nuugista biyuhu waa 2-4 jeer muggeeda. Degenaansho kiimikaad sare leh, aan milmi karin aashitada hydrochloric, si fudud ugu milmi kara alkali, oo leh sifooyin aad u wanaagsan sida qaraabo la'aanta, jilicsanaanta, dahaarka dhawaaqa, xidhashada caabbinta, iyo caabbinta kulaylka.
Horumarinta iyo Codsiga
Dhulka Diatomaceous, oo ay ugu wacan tahay sifooyinkiisa gaarka ah ee kiimikaad, ayaa si weyn loo isticmaalay sidii gargaar shaandheeye, buuxinta shaqaynaysa, side kiciya, sunta cayayaanka iyo sida bacriminta, walxaha dahaarka, adsorbent, iyo walxaha biliijka.
Gargaarka shaandhaynta:
Dhulka Diatomaceous waxa loo isticmaali karaa gargaar shaandhayn ahaan cuntada, daawada, iyo warshadaha deegaanka. Tusaale ahaan, isticmaalka sifaynta dhulka diatomaceous ee geeddi-socod khamri-samaynta waxay si joogto ah u cusbooneysiin kartaa sariirta shaandhada, xawaaraha sifeynta degdegga ah, wax-soo-saarka weyn hoos u dhig khasaaraha khamriga ilaa 1.4%, oo wanaajiya xaaladaha hawlgalka wax soo saarka. Shaandhooyinka dhulka Diatomaceous waxay si wanagsan u wanaajin karaan tayada biyaha barkada dabaasha ee wareegta daaweynta biyaha, waxayna badbaadin karaan biyaha iyo korontada hawlgalka iyo maaraynta barkadaha dabaasha. Marka labaad, dhulka diatomaceous ayaa sidoo kale si weyn loogu isticmaalay saliidaha la cuni karo, dareerayaasha afka ee dawooyinka, iyo beeraha kale.
Adsorbent:
Dhulka Diatomaceous waxaa si weyn loogu isticmaalaa daaweynta biyaha wasakhda ah sababtoo ah sifooyinka kiimikaad ee deggan, awoodda adsorption ee xooggan, waxqabadka sifeynta wanaagsan iyo milmi la'aanta asiidh kasta oo xooggan. Daawaynta ka hor ee wasakhda qashin-qubka iyadoo la adeegsanayo habka roobka qulqulka dhulka ee diatomaceous waxay si horudhac ah u dhimi kartaa CODCr iyo BOD5 ee wasakhda, ka saartaa wasakhda sida SS, waxaana inta badan loo isticmaalaa biyaha wasakhda ah ee magaalada, qashinka waraaqaha samaynta, daabacaadda iyo midabaynta biyaha wasakhda ah, gawraca biyaha wasakhda ah, biyaha wasakhda ah ee saliidda leh. , iyo biyaha wasakhda ah ee birta culus.
