Product Properties:
1.Imvura yakachena kana kuti yero zvishoma inoonekera nekunhuhwirira. Soluble mumvura; ethanol; ether uye chloroform, nezvimwewo, isina kugadzikana, yakaora kana ichidyidzana nealkali kana kunyungudutswa pamhepo yemhepo. Iyo haina kugadzikana, inoora kana ichidyidzana nealkali kana yakanyungudutswa pamhepo yemhepo.
2.Chigadzirwa chakaderera chehutu, kumedza chigadzirwa kunorambidzwa zvachose, mufambisi anofanira kupfeka giya rekudzivirira.
3.Chemical properties: Diacetone doro rine carbonyl uye hydroxyl mumorekuru, ine kemikari yeketone uye yepamusoro doro. Kuora kunoitika kana ichidziya kusvika 130 ° C kana pamusoro nealkali, ichigadzira 2 mamorekuru eacetone. Kana ichipisa ne sulfuric acid kana kutsvaga huwandu hweiodine, inobvisa mvura kuita isopropylidene acetone. Kudyidzana ne sodium hypobromite kunogadzira 2-hydroxyisovaleric acid. Catalytic hydrogenation inogadzira 2-methyl-2,4-pentanediol.
4.Ichi chigadzirwa chinogumbura maziso, ganda uye mucous membranes yekufema. Inopinda mumuviri kuburikidza nekufema uye maturakiti ekugaya, inokanganisa hurongwa hwetsinga uye inokuvadza chiropa uye mudumbu. Kufemera pamusoro pehuwandu hwemhute kunogona kuumba pulmonary edema uye kunyange coma. Kuratidzwa kwenguva refu kunogona kukonzera dermatitis.
5.Inowanikwa mufodya yekubikisa, fodya yembabvu chena, fodya yezvinonhuwira, uye chiutsi chefodya.
Product Application:
1.Diacetone doro rinogona kushandiswa sesimbi yekuchenesa, yehuni inochengetedza, inochengetedza firimu yemifananidzo uye zvinodhaka, antifreeze, solvent ye hydraulic fluids, extractant uye fiber finishing agent.
2.Diacetone doro rinoshandiswa zvakanyanya semugadziri we electrostatic spray paints, celluloid, nitrocellulose, mafuta, mafuta, wax uye resins. Diacetone doro inzvimbo yekubikira yakakwira organic solvent. Iyo viscosity yakaderera uye mhedzisiro yekushisa pane viscosity idiki. Inoshandiswa se solvent uye pendi stripper ye cellulose ester pendi, inki yekudhinda, synthetic resin pendi nezvimwe.
3.Inoshandiswa zvakanyanya sechinhu chinogadziriswa che resin, electrostatic spray paints, celluloid, nitro fibres, mafuta, mafuta uye wax. Inoshandiswawo sesimbi yekuchenesa, huni inochengetedza, inochengetedza yemifananidzo firimu nemishonga, antifreeze, hydraulic mafuta solvent, extractant uye fiber finishing agent. Iyo zvakare imhando ye organic synthesis yepakati.
4.Cosmetic solvent, inonyanya kushandiswa sechipikiri chembambo uye zvimwe zvizoro zvepamusoro-soro kuvira kunopisa. Kazhinji inogadzirwa ne-low-boiling point solvents uye-medium-boiling point solvents mune zvakasanganiswa zvinonyungudutsa, kuitira kuwana zvakakodzera evaporation rate uye viscosity.
Chigadzirwa Chekuchengetedza Notes:
1.Chengeta munzvimbo inotonhorera, ine mhepo yekuchengetera mhepo.
2.Gara kure nemoto uye kupisa sosi, dzivisa chiedza chezuva.
3.Chengetedza mudziyo wakavharwa.
4.Iyo isiri-corrosive kune simbi, uye inogona kuchengetwa musimbi, simbi yakapfava kana midziyo yealuminium, asi ine erosive effect pamhando dzakawanda dzepurasitiki.
5.Chengetedza uye kutakura uri wega kubva kune oxidising agents uye acids.
6.Iron bucket kana girazi bhodhoro rakazara nemapuranga emapuranga ekugadzira zvinhu.
