Guryaha Alaabta:
1.White ama wax yar huruud ah dareere hufan oo leh caraf udgoon.Biyo ku milmay;ethanol;ether iyo chloroform, iwm., aan degganayn, qudhuntay marka ay la falgalayaan alkali ama la distilled atmospheric cadaadiska.Waa mid aan degganayn, way qudhuntaa marka ay la falgasho alkali ama kala-baxa cadaadiska atmospheric.
2.Alaabtu waa sun yar, liqidda alaabta si adag ayaa loo mamnuucay, hawlwadeenku waa inuu xirtaa qalabka ilaalinta.
3.Qalabka Kiimikada: Khamriga diacetone wuxuu ka kooban yahay carbonyl iyo hydroxyl ee molecule, oo leh sifooyinka kiimikada ketone iyo alkolada sare.Burburku wuxuu yimaadaa marka lagu kululeeyo 130 ° C ama ka badan alkal, soo saara 2 molecules oo acetone ah.Marka lagu kululeeyo sulfuric acid ama qiyaasta qiyaasta iodine, waxay fuuqbaxdaa si ay u sameyso isopropylidene acetone.Is dhexgalka sodium hypobromite wuxuu soo saaraa 2-hydroxyisovaleric acid.Haydaroojin katalytic wuxuu abuuraa 2-methyl-2,4-pentanediol.
4. Alaabtaani waxay ka xanaajisaa indhaha, maqaarka iyo xuubka xuubka neefsiga.Waxa ay jidhka ka soo gashaa hab-dhiska neefsiga iyo dheefshiidka, taas oo saamaysa hab-dhiska neerfaha, waxyeelo gaadhsiisa beerka iyo caloosha.Neefsashada xoogga badan ee uumiga waxay sameyn kartaa barar sambabada iyo xitaa miyir-beelka.Soo-gaadhista muddada-dheer waxay u horseedi kartaa dermatitis.
5. Waxaa laga helay tubaakada dubista, tubaakada feeraha cad, tubaakada xawaashka, iyo qiiqa sigaarka.
Codsiga Alaabta:
Khamriga 1.Diacetone waxaa loo isticmaali karaa nadiifiyaha birta, ilaalinta alwaax, ilaalinta filimka sawirada iyo daroogooyinka, antifreeze, dareeraha dareeraha hydraulic, soosaar iyo wakiilka dhamaystirka fiber.
2.Diacetone khamriga waxaa si weyn loo isticmaalaa sida dareere loogu talagalay rinji buufin elektrostatic, celluloid, nitrocellulose, dufan, saliidaha, waxes iyo resins.Khamriga diacetone waa dareere dabiici ah oo karkarinaya.Viscosity-ku wuu hooseeyaa, saamaynta heerkulku ku leeyahay viscosity-kuna waa yar yahay.Waxa loo isticmaalaa sida dareere iyo rinji-saarre loogu talagalay rinjiga ester cellulose, qalin daabacaadda, rinjiga resin synthetic iwm.
3. Si ballaaran loo isticmaalo sida dareere loogu talagalay resins, rinjiga buufinta elektrostatic, celluloid, fibre nitro, dufan, saliid iyo waxes.Waxa kale oo loo istcimaalaa nadiifiye bir ah, alwaax ilaalin ah, ilaaliye filim sawireed iyo daawo, baraf-diid, dareeraha saliida hadhka, soo saarista iyo wakiilka dhamaystirka fiber.Sidoo kale waa nooc ka mid ah dhexdhexaadiyeyaasha isku-dhafka dabiiciga ah.
4.Waxyaabaha la isku qurxiyo, oo inta badan loo isticmaalo sidii ciddiyaha ciddiyaha iyo waxyaabaha kale ee la isku qurxiyo ee dareeraha barta karkarinta sare.Caadi ahaan waxaa lagu qaabeeyey dareerayaasha dhibicda karkarinaysa iyo kuwa dhexdhexaadka ah ee dhexdhexaadka ah ee la isku daray, si loo helo heerka uumiga ku habboon iyo viscosity.
Qoraalada Kaydinta Alaabta:
1. Ku kaydi bakhaar qabow oo hawo leh.
2. Ka fogow dabka iyo isha kulaylka, iska ilaali iftiinka qorraxda tooska ah.
3.Ka ilaali weelka oo xiran.
4. It is non-corrosive to birta, waxaana lagu kaydin karaa birta, birta jilicsan ama aluminium weel, laakiin waxa ay leedahay saamayn erosive on noocyo badan oo balaastig ah.
5. Ku kaydi oo gaadiidka si gooniya uga soocan walxaha oksaydhka ah iyo asiidhka.
6.Baaldiga birta ah ama dhalada dhalada waxaa lagu buuxiyaa alaab alwaax ah.
