Calcium Oxid

sharaxaad gaaban:

lime degdega ah guud ahaan waxa ku jira lime aad u kulul, dayactirka lime ee kulaylka badan waa mid gaabis ah, haddii koollada dambaska dhagaxa ay mar kale adkaato, waxay keeni doontaa dildilaaca balaadhinta balaadhinta gabowga awgeed.Si loo baabi'iyo dhibaatadan gubasho lime, lime waa in sidoo kale "da'da" ilaa 2 toddobaad ka dib dayactirka.Qaabku waa caddaan (ama cawl, bunni, cad), amorphous, oo nuugaya biyaha iyo kaarboon laba ogsaydh hawada ka imanaya.Calcium oxide waxay la falgashaa biyo si ay u samayso kalsiyum hydroxide waxayna bixisaa kulayl.Ku milmay biyo acidic ah, oo aan lagu milmin khamriga.Maqaallada daxalka ah ee alkaline-ka ah, koodhka khatarta qaranka :95006.Lime waxay si kimikal ah ula falgashaa biyo waxayna isla markiiba kulaylaysaa heerkul ka sarreeya 100°C.

Faahfaahinta Alaabta

Tilmaamaha waa la bixiyay

budo cad (content ≥ 95%/99%)

Balaadhan (content ≥ 80%/85%)

(Baaxadda tixraaca codsiga 'isticmaalka alaabta')

Sifada jidheed iyo budada badan/granular/budada ah ee lime degdega waa isku mid .

Ka dib markii lime laga sifeeyo foornada, badeecada ugu fiican ayaa guud ahaan laga sameeyaa liin degdeg ah.

Inta soo hartay ee dambaska hoose ee shaandhada waxaa loo isticmaali karaa sida liin yar ama budada lime hooseeya, qiimuhu wuxuu noqon doonaa mid ka hooseeya dambaska wanaagsan, qeexitaanka waxaa lagu dooran karaa iyadoo loo eegayo muuqaalka isticmaalka.

EVERBRIGHT® sidoo kale waxay ku siin doontaa habaysan: nuxurka/caddaannaanshaha/qaybaha/qiimaha/qiimaha/midabka/qaabka baakaynta/ baakadaha iyo badeecooyinka kale ee gaarka ah ee ku habboon xaaladahaaga isticmaalka, oo bixiya muunado bilaash ah.

Isticmaalka Alaabta

Qalabka dhismaha

Qulqulka biraha, dardar-geliyaha sibidhka, qulqulka fosfoorka.

Buuxiyaha

Waxaa loo isticmaali karaa sida buuxinta, tusaale ahaan: loo isticmaalo sida buuxinta xabagta epoxy, Waxay diyaarin kartaa mishiinada beeraha ee No. 1, No. 2 xabagta iyo koollada epoxy biyaha hoostooda, iyo sidoo kale loo isticmaalo sida wakiilka falcelinta pre-reaction leh 2402 resin. .

Daawaynta wasakhda Aashitada

Qaar badan oo ka mid ah biyaha wasakhda warshadaha oo ku daray aluminium taxane ah wakiilka agglutination (polyaluminum chloride, warshadaha aluminium sulfate, iwm) ama bir taxane agglutination wakiilka (polyferric chloride, polyferric sulfate) soo saaray kooxo yaryar oo kala firdhiyey uumiga.Taangiga sedimentation ma fududa in la dego, ku darida kalsiyum oxide waxay kordhin kartaa cuf-jiidka gaarka ah ee flocculant waxayna dedejin kartaa qulqulka qulqulka.

Kuleyliyaha wuxuu demiyaa ilaalinta

Awoodda nuugista qoyaanka ee lime waxaa loo isticmaalaa in lagu ilaaliyo dusha birta ee nidaamka uumiga biyaha kululeeyaha qalalan iyo ka hortagga daxalka, kaas oo ku habboon ilaalinta deactivation muddada dheer ee cadaadiska hooseeya, cadaadiska dhexdhexaadka ah iyo kuleyliyaha durbaanka awoodda yar.

Wax soo saarka alaabta

Loo isticmaalo sida alaabta ceeriin, waxay soo saari kartaa kaarbiid calcium, ash soodhaha, budada bleaching, iwm, oo sidoo kale loo isticmaalo maqaarka, nadiifinta biyaha wasakhda ah, calcium hydroxide iyo xeryahooda kala duwan ee calcium;Calcium hydroxide waxaa lagu diyaarin karaa falcelinta biyo, isla'egta falcelinta: CaO+ h2o = Ca(OH)2, waxaa iska leh falcelinta isku dhafka ah.
