Habka soo saarista dareeraha
Habka loo isticmaalo dareeraha organic si loo soo saaro oo loo kala saaro walaxda la soo saaray iyo xal aqueous ah oo aan la arki karin waxaa loo yaqaannaa habka dheecaanka dareeraha dareeraha ah, oo loo soo gaabiyo habka soo saarista dareeraha. Waa hannaan wareejin ballaaran oo ka gudbisa walxaha hal weji dareere ah una gudbiya mid kale.
Soo saarista millatariga ayaa hore loogu dabaqay warshadaha batroolka, kimistariga organic, kimistariga daawada iyo kimistariga falanqaynta. Si kastaba ha ahaatee, 40-kii sano ee la soo dhaafay, ay sabab u tahay horumarinta sayniska tamarta atomiga iyo teknoolajiyada, baahida qalabka ultrapure iyo wax soo saarka element raad, saarista dareeraha ayaa si weyn loo horumariyo in warshadaha shidaalka nuclear, metallurgy dhif ah iyo warshadaha kale.
Marka la barbar dhigo hababka kala soocidda sida roobka darajooyinka, crystallization grade, iyo ion sarrifka, fiirsashada dareeraha ayaa taxane ah oo faa'iidooyin sida saamaynta kala soocidda wanaagsan, awoodda wax soo saarka ballaaran, ku habboonaanta wax soo saarka degdeg ah oo joogto ah, iyo fududahay in la gaaro gacanta si toos ah. Sidaa darteed, waxay si tartiib tartiib ah u noqotay habka ugu muhiimsan ee lagu kala saaro xaddi badan oo dhul dhif ah.
Qalabka kala-soocida ee habka miirista dareeraha waxaa ka mid ah haanta caddaynta isku-dhafka ah, soosaaraha centrifugal, iwm. Soosaarayaasha loo isticmaalo nadiifinta dhulka dhifka ah waxaa ka mid ah: soosaarayaasha cationic oo ay matalaan esters fosfateed acidic ah sida P204 iyo P507, dareeraha sarrifka anion N1923 oo ay matalaan amines, iyo soosaarayaasha dareeraha ah oo ay matalaan esters fosfateed dhexdhexaad ah sida TBP iyo P350. Soosaarayaashani waxay leeyihiin viscosity sare iyo cufnaanta, taas oo adkeyneysa inay ka soocaan biyaha. Caadi ahaan waa lagu qasi karaa oo dib ayaa loo isticmaalaa dareerayaasha sida kirosene.
Habka soo saarista guud ahaan waxa loo qaybin karaa saddex marxaladood oo waaweyn: soo saarid, dhaqid, iyo soo saarid gadaal ah. Alaabta ceeriin ee macdanta laga soo saaro biraha dhifka ah ee dhulka iyo walxaha kala firdhiyey.
