荧光增白剂 OB-1的相关介绍.doc

奥珞斯荧光增白剂 OB-1的相关介绍【1】化学名称：2,2-(4,4-二苯乙烯基)双苯并恶唑 【2】性能指标： 分子式： C28H18N2O2 分子量： 414.4 含 量： 99.0% 外 观： 黄绿色结晶粉末 熔 点： 353359C 气 味： 无 最大吸收光谱波长：374nm 最大荧光发射波长：434nm【3】应用： 荧光增白剂OB-1是一种用于聚酯纤维的高效荧光增白剂，同时广泛应用于ABS、PS、HIPS、PA（尼龙）、PC（聚碳酸酯）、PP、EVA和硬质PVC等塑料，具有极佳的增白效果，优异的热稳定性，极少的添加量等特点。【4】用量：每100kg聚合物中添加荧光增白剂OB-1的用量（参考用量）透明： 添加量为0.00250.005% （2.5g-5g）一般用量为： 0.00250.025% （2.5g-25g） 不超过0.03% （30g）在聚合物中添加任何紫外线吸收剂时，应注意适当调整荧光增白剂 OB-1的最佳用量。【5】用法： 因增白剂加入量较少，应彻底分散增白剂，使增白剂能均匀地分散在整个聚合物中。如果采用增白剂浓缩母粒，则更易达到充分的分散效果。【6】注意： 对于PE和软质PVC使用荧光增白剂OB-1时，应特别注意用量的控制，过多用量会发生增白剂迁移现象【7】安全和管理： 本品可按一般工业化学品管理，使用时应戴手套和防护眼镜，避免直接与皮肤或眼睛接触。若沾上皮肤，用清水加肥皂冲洗干净即可。【8】包装： 25kg/纸板桶（内衬双层塑料袋）【9】储存条件：密封阴凉处储存Ouroboros Fluorescent Brightener OB-11. Chemical Name: 4,4-Bis(2-benzoxazolyl)stilbene2. Performance index: Structural formula: C28H18N2O2 Formula weight: 414.4 Content: 99.0% Appearance: Kelly crystalline powder Melting point: 353359C Smell: tasteless Absorption wavelength(Max):374nm Emission wavelength (Max): 434nm3. Purpose Fluorescent Brightener OB-1 is the effective fluorescent brightener that use in polyester fibre . It is widely used in the plastic of ABS、PS、HIPS、PA、PC、PP、EVA and hard PVC, that has excellent whitening effect , good thermal stability and little additive amount.4. Use level: (Reference amount) the amount of Fluorescent Brightener OB-1 in each 100kg polymer Transparency; additive amount: 0.00250.005% （2.5g-5g） Generally amount: 0.00250.025% （2.5g-25g） no more than 0.03% （30g）When it is added any ultraviolet absorbent in the polymer, it need pay attention to adjust the best amount of Fluorescent Brightener OB-1 .5. PurposeBecause of the less amount of brightening agent, it is completed dispersed brightening agent, that can make brightening agent be dispersed uniformly in the whole polymer. If brightening agent is concentrated masterbatches, it will be easy to achieve the effect of decentralization6. AttentionIt need to pay attention to control the amount of it for PE and soft PVC. An excess of the product will appear the transport phenomena of brightening agent.According to industrial chemicals management, when we use it, we need wear gloves and eye protection to avoid directly contacting with eye and skin. When the skin is stained with it,
