液体增白剂及存储办法
Liquid whitening agents and storage methods
造纸用液体荧光增白剂HPE 功能外观: 琥珀色通明液体化学结构: 二胺基二苯乙烯四磺酸衍生物分子式:C 14 H 14 N 2 O 12S 4 耐酸碱性: 在pH3~12范围内适用(特殊情况除外) 溶解性: 能与水以任何份额溶解产品pH值: 7~10 密度(25℃): 1.11~1.20g/cm? 含量:35力分粘度(25℃): ≤50m.pa.s 离子性: 呈阴离子性牢度性: 与同类产品比较,HPE增白剂具有相同日晒牢度及耐酸碱牢度毒性对家兔的试验标明,对皮肤及粘膜安排均无刺激性,在正常的出产运用中,不会对人体健康带来任何影响。在贮存、转移及运用HPE时,应按照惯例化学品的卫生及安全规则进行。增白原理造纸用液体荧光增白剂HPE是一种光学增白剂,它能吸收紫外光而激起兰紫色的可见光,然后使被染物显得更白更艳.
Liquid fluorescent whitening agent HPE for paper making: Amber clear liquid chemical structure: Diamino stilbene tetrasulfonic acid derivative molecular formula: C 14H 14N 2O 12S 4 acid and alkali resistance: applicable in the pH range of 3-12 (except in special cases) solubility: can dissolve with water in any share of the pH value of the product: 7-10 density (25 C): 1.11-1.2 0 g / cm? Content: 35 force fraction viscosity (25 C): < 50 m. Pa. s ionicity: anionic fastness: compared with similar products, HPE whitening agent has the same sun fastness and acid and alkali fastness toxicity to rabbits test marking, no irritation to skin and mucosal arrangement, in normal production and application, will not bring any responsibility to human health. What does it affect? When storing, transferring and using HPE, it should be carried out in accordance with the hygiene and safety rules of conventional chemicals. The liquid fluorescent whitening agent HPE for paper making is an optical whitening agent. It can absorb ultraviolet light and excite blue-purple visible light, then make the dyed products appear more white and bright.
适用范围对纸浆进行荧光增白对内施胶纸、加填料纸、未加填料及纸板的纸浆中于pH4.5~10条件下运用HPE液体荧光增白剂进行荧光增白在外表施胶进程中进行荧光增白可在以水溶性淀粉为根底的施胶液中及与聚乙烯醇(PVA),羧甲基纤维素(CMC)及海藻盐同浴运用. 在涂料进程中进行荧光增白荧光增白剂HPE对涂布进程进行增白,要达抱负作用,需用适量的辅助粘合剂,如PVA、CMC等。
Applicability of fluorescent whitening of paper pulp to fluorescent whitening of internal sizing paper, packed paper, un-packed and paperboard pulp at pH 4.5~10 using HPE liquid fluorescent whitening agent in the process of external sizing fluorescent whitening can be used in the sizing solution with water-soluble starch as the base and with polyvinyl alcohol (PVA), carboxymethyl fiber (CMF). Vitamin (CMC) and algae salt are used in the same bath. Fluorescent whitening fluorescent whitening agent HPE is used to whiten the coating process in order to achieve the desired effect. Appropriate amount of auxiliary adhesives, such as PVA and CMC, are needed.

明显长处在任何条件下能够恣意倍量的水溶解均匀,并能在纸浆中快速均匀涣散,然后确保制品纸质量的安稳。比VBL增白剂具有更好的耐侯性及耐光性,制品纸不易黄变。即使在pH值很低的条件下运用,仍可取得良好的增白作用,这是VBL增白剂远不及的。产品呈液态,不象VBL增白剂溶解时构成粉尘污染环境,维护了操作人员的身体健康,且可接连加料,运用特别方便。应用在配料内对纸浆进行增白液体荧光增白剂HPE能够间歇方法参加碎浆机或混合槽中运用,参加时一般不需稀释,但需使纸浆与HPE充沛混合均匀。在运用明矾或阳离子助剂时,应先参加HPE增白剂,不宜将其一同运用。HPE增白剂也可接连参加制浆储藏液中或以原液构成直接在纸浆储藏液体系的合适部位参加。
The obvious advantage is that under any conditions can be arbitrarily multiple water solubility uniform, and can quickly uniform dispersion in the pulp, and then ensure the stability of the quality of paper products. Compared with VBL brightener, it has better weatherability and light resistance, and the paper is not easy to yellowing. Even in very low pH conditions, still can achieve good whitening effect, which is far less than VBL whitening agent. The product is liquid, unlike VBL whitening agent when dissolved to form dust pollution environment, to maintain the health of the operator, and can be continued to feed, especially convenient to use. HPE, a liquid fluorescent whitening agent, can be used intermittently in pulp crusher or mixing tank. It does not need to be diluted, but must be mixed well with HPE. When alum or cationic additives are used, HPE brighteners should not be used together. HPE whiteners can also be added to the pulping storage liquor or the pulp storage liquor directly in the appropriate part of the pulp storage liquid system.
虽然HPE增白剂对纤维素纤维具有较高的亲和力,但其所取得的白度取决于原浆的白度和增白时刻,体系中浆料稠度比较高时参加增白剂,可取得较抱负的增白作用。对纸浆增白合适的pH值为4.0~10。主张用量:HPE液体增白剂对绝干纸浆分量为0.05~1.4%范围内选用。在外表施胶进程中进行增白荧光增白剂HPE能够与施胶中常用的淀粉等一同运用以到达比较好的增白作用。HPE能与CMC、PVA及阴离子、弱阳离子组成施胶剂一同作用。在原纸制作进程中,原纸的pH值会对其增白作用发生较大影响。
Although HPE whitening agent has a high affinity for cellulose fiber, the whiteness obtained depends on the whiteness and whitening time of the original pulp. When the consistency of the pulp is the highest, whitening agent can be used to achieve a more ambitious whitening effect. The suitable pH value for pulp whitening is 4.0~10. Dosage: HPE liquid brightener for dry dry pulp content of 0.05~1.4%. HPE, a fluorescent whitening agent, can be used together with starch in sizing process to achieve the best whitening effect. HPE can react with CMC, PVA and anion and weak cation as sizing agent. In the process of making base paper, the pH value of base paper will have a great influence on its whitening effect.
当流浆前pH值大于5时,可取得较抱负增白作用。若pH值小于5,HPE增白剂比一般二苯乙烯双三嗪型增白剂增白作用更为抱负,如常用的VBL增白剂。主张用量:在施胶液中的浓度为0.5~12g/l。在特殊情况下,如因为设备的要素而使淀粉的上染率较低,则HPE增白剂的用量可增加到在施胶液中浓度为25g/l。在涂布进程中进行增白 HPE增白剂亲水性极强,具有十分优良的贮存安稳性。长时刻置于0℃以下,HPE增白剂将凝结,当到达常温,或在50℃以下加热消融后,不影响运用。 HPE液体增白剂在未运用前对光灵敏,请注意避免阳光直接照耀。
When the pH value is more than 5 before flowing, it can achieve a more desirable whitening effect. If the pH value is less than 5, HPE whitening agent is more ambitious than ordinary stilbene ditriazine whitening agent, such as the commonly used VBL whitening agent. Dosage: the concentration in the sizing solution is 0.5~12g/l. In special cases, if the dyeing rate of starch is low due to the equipment elements, the amount of HPE whitening agent can be increased to 25 g/l in the sizing solution. In the coating process, whitening agent HPE has strong hydrophilicity and has excellent storage stability. The HPE whitening agent will coagulate when it is kept below 0 C for a long time, and will not affect its application when it reaches normal temperature or is heated and ablated below 50 C. HPE liquid whitening agent is sensitive to light before it is applied. Please avoid direct sunlight.
