Zinc oxide Chemische Eigenschaften,Einsatz,Produktion Methoden

  • Chemische Eigenschaften Zinc oxide is an amorphous, white or yellowish-white powder. Odorless.
  • Chemische Eigenschaften Zinc oxide is yellowish and powder like.
  • Verwenden Antibiotic
  • Verwenden Preparation of zinc standard solutions.
  • Verwenden zinc oxide has been used to protect, soothe, and heal the skin. Zinc oxide provides an excellent barrier to the sun and other irritants. It is somewhat astringent, anti-septic, and anti-bacterial. When used in sunscreen preparations, it provides both uVA and uVB protection, and can contribute to and/or increase SPF. At the appropriate particle size, zinc oxide is transparent in the visible light spectrum but opaque in the uVC ranges, thereby avoiding a whitening effect when incorporated into sunscreen preparations. Zinc oxide is included on the FDA’s list of approved sunscreen chemicals. It demonstrates an impressive synergistic effect when combined with organic sunscreens. Zinc oxide is also used when a white color is desired for a product. It is obtained from zinc ore, a commonly found mineral, and is relatively non-allergenic.
  • Definition zinc oxide: A powder, white whencold and yellow when hot, ZnO; r.d.5.606; m.p. 1975°C. It occurs naturallyas a reddish orange ore zincite,and can also be made by oxidizinghot zinc in air. It is amphoteric,forming zincates with bases. It isused as a pigment (Chinese white) and a mild antiseptic in zinc ointments.An archaic name is philosopher’swool.
  • Definition Zincite is a mineral form of zincoxide, ZnO.
  • CHEMISCHE GEFAHREN Reagiert sehr heftig mit Aluminium- und Magnesiumpulver, und mit Chlorkautschuk beim Erhitzen. Feuer- und Explosionsgefahr.
  • ARBEITSPLATZGRENZWERTE TLV: 2 mg/m?(als TWA); (Alveolengängige Fraktion); 10 mg/m?(als STEL); (Alveolengängige Fraktion); (ACGIH 2005).
    MAK: (als Rauch) 1 mg/m?(Alveolengängige Fraktion); Spitzenbegrenzung: überschreitungsfaktor I(1); (DFG 2005).
  • AUFNAHMEWEGE Aufnahme in den Körper durch Inhalation des Aerosols und durch Verschlucken.
  • INHALATIONSGEFAHREN Eine gesundheitsschädliche Partikelkonzentration in der Luft kann schnell erreicht werden, besonders für Zinkoxidrauch-Partikel.
    Inhalation des Rauches kann Metalldampffieber verursachen. Die Substanz (als Rauch) reizt die Atemwege. Die Auswirkungen treten u.U. verzögert ein (s.Anm.).
  • LECKAGE Verschüttetes Material in Behältern sammeln; falls erforderlich durch Anfeuchten Staubentwicklung verhindern. Reste sorgfältig sammeln. An sicheren Ort bringen. Persönliche Schutzausrüstung: Atemschutzgerät, P2-Filter für schädliche Partikel.
  • Allgemeine Beschreibung Crude zinc oxide is a yellow-gray granular solid with no odor. Zinc oxide has a specific gravity of 4.4. Zinc oxide is insoluble in water. The primary hazard is the threat posed to the environment. Immediate steps should be taken to limit its spread to the environment. Prolonged inhalation of the dust may result in metal fume fever with symptoms of chills, fever, muscular pain, nausea and vomiting.
  • R-Sätze Betriebsanweisung: R50/53:Sehr giftig für Wasserorganismen, kann in Gewässern längerfristig schädliche Wirkungen haben.
    R20:Gesundheitsschädlich beim Einatmen.
  • Air & Water Reaktionen Slowly decomposed(hydrolyzed) in water. Insoluble in water.
  • Reaktivität anzeigen ZINC OXIDE is insoluble in water. What little solubility Zinc oxide has yields aqueous solutions that are neutral in pH. Intimate mixtures of zinc oxide and chlorinated rubber with or without hydrocarbons or chlorinated solvent react violently, even explosively upon heating [Chem. Trade J., 1962, 151, 672]. Slow addition of zinc oxide to cover the surface of linseed oil varnish caused generation of heat and ignition, [Chem. Trade J., 1933, 92, 278].
  • S-Sätze Betriebsanweisung: S60:Dieses Produkt und sein Behälter sind als gefährlicher Abfall zu entsorgen.
    S61:Freisetzung in die Umwelt vermeiden. Besondere Anweisungen einholen/Sicherheitsdatenblatt zu Rate ziehen.
    S7/9:Behälter dicht geschlossen an einem gut gelüfteten Ort aufbewahren.
  • Health Hazard Exposures to zinc oxide metal fume cause several health disorders. The symptoms of toxicity include, but are not limited to, fever, chills, muscle ache, nausea, fever, dry throat, cough; lassitude (weakness, exhaustion), metallic taste, headache, blurred vision, low back pain, vomiting, malaise (vague feeling of discomfort), chest tightness, dyspnea (breathing diffi culty) and decreased pulmonary function. The overexposure to zinc oxide fumes in workplaces produce symptoms known as metal fume fever or “zinc shakes”; an acute, selflimiting condition. Chronic exposure to zinc oxide may cause respiratory tract irritation with nasopharyngitis and laryngitis.
  • Brandgefahr Some may burn but none ignite readily. Containers may explode when heated. Some may be transported hot.
  • Landwirtschaftliche Anwendung Zinc oxide (ZnO) is a zinc fertilizer. It is a white powder when cold and yellow when hot, and contains approximately 78% zinc.
    Zinc oxide occurs in nature as a reddish-orange colored zincite, and is made by oxidizing hot zinc in air. It is an amphoteric oxide forming zincates, by reacting with bases and zinc salts with acids. It is used as a white pigment and as a mild antiseptic in ointments. An archaic name of zinc oxide is philosopher's wool.
    Foliar applications with zinc oxide reduce the foliage damage. Zinc oxide, applied by way of seed coatings, root dips or tree injections, corrects the zinc deficiency. Dipping potato seeds in 2% zinc oxide suspension overcomes zinc deficiency satisfactorily. A similar method is used for pre-plant dipping of the roots of rice seedlings.
  • Sicherheitsprofil Moderately toxic to humans by ingestion. Poison experimentally by intraperitoneal route. An experimental teratogen. Other experimental reproductive effects. Human systemic effects by inhalation of freshly formed fumes: metal fume fever with chills, fever, tightness of chest, cough, dyspnea, and other pulmonary changes. Mutation data reported. A s h and eye irritant. Has exploded when mixed with chlorinated rubber. Violent reaction with Mg, linseed oil. When heated to decomposition it emits toxic fumes of ZnO. See also ZINC COMPOUNDS.
  • mögliche Exposition Zinc oxide is primarily used as a white pigment in rubber formulations and as a vulcanizing aid. It is also used as an antiinflammatory agent; in photo copying; paints, chemicals, ceramics, lacquers, and varnishes; as a filler for plastic; in cosmetics; pharmaceuticals, and calamine lotion. Exposure may occur in the manufacture and use of zinc oxide and products, or through its formation as a fume when zinc or its alloys are heated. HC may have been used as a Choking/Pulmonary Agent.
  • Erste Hilfe If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a corticosteroid spray or other inhalation therapy. If metal fume fever develops, it may last less than 36 hours.
  • Versand/Shipping UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.
