吸水树脂高分子
吸水树脂因其具有吸水量大，保水能力强和分子聚合物的许多性能，如力学性能，可塑性，易加工和便于使用等，近二十年来发展速度，被广泛应用于一次性卫生用品，农用领域，光电缆业和防水行业。
Super absorbent polymer super absorbent polymers because it has a large amount of water, water retention ability and many properties of polymer, such as mechanical properties, plasticity, easy processing and convenient use, development in recent twenty years, has been widely used in disposable sanitary products, agricultural areas, photoelectric cable industry and waterproofing industry.
一次性卫生用品是
高分子吸水树脂的主要的也是较为成熟的应用领域，约占
高分子吸水树脂总用量的70%-80%，包括婴幼儿护理卫生用品，妇女护理卫生用品和成人失禁卫生用品。由于上述产品所处理的液体不是简单的水，而是含有盐、矿物质以及血液的混合物。所以，我们在测试高分子吸水树脂和纸尿裤时使用的是生理盐水和人造血浆，以更符合实际使用时的状况。
Disposable sanitary products is the main and mature application field of polymer absorbent resin, which accounts for 70%-80% of the total amount of polymer absorbent resin, including infant care and hygiene products, women's health care products and adult incontinence hygiene products. The liquid treated by these products is not a simple water, but a mixture of salt, minerals and blood. So, when we test high polymer water absorbent resin and paper diapers, we use normal saline and artificial plasma in order to be more suitable for actual use.
纸尿裤的技术要求纸尿裤是以木浆和高分子吸水树脂为主构成的吸收芯体，以及无纺布，纸巾，松紧带和粘合剂等组成。消费者对纸尿裤的要求是婴儿穿戴时不产生渗漏和吸水及保水性，并使婴儿皮肤表面干爽，穿戴舒适。纸尿裤生产商对尿裤产品的性能要求主要表现在保水性能，穿渗速度，液体扩散和防漏等。而尿裤的原材料对尿裤的每一种性能所作的贡献是不同的，如表面导流层的无妨布对穿渗速度，液体扩散范围影响比较大，而高分子吸水树脂会对尿裤等回渗性能产生比较大的影响，大约有70% 的贡献来自吸收树脂。
Diapers are the technical requirements. Diapers are made of wood pulp and polymer absorbent resin, and non-woven fabrics, paper towels, elastic belts and adhesives. Consumers' requirement for diapers is that babies do not have leakage, water absorption and water retention when they are worn, and make the skin dry and comfortable. The performance requirements of diaper manufacturers are mainly in water retention, permeation speed, liquid diffusion and leakage prevention. The raw materials for each diaper diaper on the performance of the contribution is different, such as the surface layer of fine cloth to wear diversion infiltration velocity, the liquid diffusion range of relatively large impact, and super absorbent polymer, urine trousers to rewet performance have a relatively large impact, about 70% of the contribution from the absorption resin.
高分子吸水树脂的性能高分子吸水树脂的出现带动了纸尿裤使用和生产的革命，由于它的高吸水性以及良好的保水性能使现代的一次性纸尿裤为母亲带来方便的同时也为婴儿带来干爽和舒适。作为尿裤原材料的高分子吸水树脂具有许多特性，如吸收速率，吸收量，加压下的吸收量和保水量。
The performance of super absorbent polymers of super absorbent polymers led to the use of diapers and production revolution, due to its high water absorption and good water retention properties of the disposable diapers modern convenient but also to bring the baby dry and comfortable for the mother. Polymer absorbent resin, as a raw material for urine pants, has many characteristics, such as absorption rate, absorption, absorption and water retention under pressure.
1、吸收速率
1. Absorption rate
它显示高分子吸水树脂在某个时间段中最大的吸收量，一般数据是以开始的30s,60s 或180s 内1g 高分子吸水树脂所能吸收的生理盐水。
It shows that the maximum absorption amount of polymer absorbent resin in a certain time period, the general data is based on the initial 30s, 60s or 180s 1g polymer absorbent resin can absorb physiological saline.
2、吸收量
2. Absorptive capacity
它显示1g 高分子吸水树脂最大的所能吸收的生理盐水量。加压下的吸收量(0.70pa) ：显示在受到0.7pa 压力的情况下，1g 高分子吸水树脂最大的吸收量。这是因为婴儿在很多情况下是坐着或躺着的，而这时尿液往往是在人体的压迫下吸收尿液。这种测试方式就是为了模拟并了解吸收树脂在加压下的吸收情况。
It shows the maximum amount of physiological saline absorbed by the 1g macromolecule absorbent resin. The amount of absorption under pressure (0.70pa): the maximum absorption of the 1g macromolecule absorbent resin is shown under the condition of 0.7pa pressure. This is because the baby sits or lies in many cases, and the urine is often absorbed by the body under the pressure of the body. This method is to simulate and understand the absorption of the absorption resin under pressure.
3、保水量
3. Water conservation
它显示1g 高分子吸水树脂在吸收最大的生理盐水量后经过1400 转的离心处理所能保有的最大的生理盐水量。它表示了高吸收树脂真正能保持与固定的生理盐水量。
It shows the maximum amount of physiological saline that the 1g macromolecule absorbent resin can retain after 1400 turns of centrifugation after the absorption of the maximum amount of physiological saline. It indicates that the high absorption resin can be kept and fixed in normal saline.
4、比重和颗粒分布
4, specific gravity and particle distribution
它显示高分子吸水树脂的比重和颗粒大小以及分布情况。
It shows the proportion and particle size and distribution of the polymer water absorbent resin.
这些特性对纸尿裤的性能都有不同的贡献，所以我们并不认为某一数据高就一定是好的产品，但是相对而言，保水量和加压下的吸收量是比较重要的。
There are different characteristics on the performance contribution of these diapers, so we do not think that a certain high data is a good product, but relatively speaking, the amount of water retention and absorption under pressure is more important.
对纸尿裤性能的作用就纸尿裤的要求以及高分子吸收树脂在纸尿裤中所起的作用而言，保水量和加压下的吸收量是比较重要的性能。其次是吸水速率和吸水量。现在尿裤行业中，无论是纸尿裤制造商还是尿裤分销商都十分关注吸水速率，认为吸水快的尿裤是好的尿裤，特别是尿裤制造商将吸水速率作为评介高分子吸水树脂优劣的唯一标准，这对尿裤的发展产生一种误导，使我们的尿裤无法及时跟上世界先进尿裤发展的趋势。
The effect of diapers on the requirements of paper diapers and the role of polymer absorption resins in paper diapers are important. The second is the rate of water absorption and water absorption. Now the diaper industry, whether manufacturers or distributors of diapers diapers are very concerned about the water absorption rate, that diaper absorbent fast pants is good, especially the diaper manufacturers will be water absorption rate as the only standard of water absorbent resin quality, produce a misleading the pants, the pants we cannot keep up with the world advanced diaper development trends timely.
我们剖析纸尿裤芯片可以发现其中有两种原料组成：高分子吸水树脂和木浆。高分子吸水树指具有高吸水量和高吸水保有量的特征，它的吸水量和保水量是木浆的几十位，而木浆堆积在一起具有良好的毛细管，产生较高的导流分散作用，它的吸水速率大约是高分子吸水树脂的5-6 位。所以两者的性能具有互补性，合适的配比和混合构成的纸尿裤芯片能达到最佳吸收速率和吸水保有量的效果。如果只关注的是速率，则木浆将裤芯片的最佳原材料。而我们使用纸尿裤并重点推广宣传的是其能保持婴儿屁股的皮肤干爽，高分子吸水树脂所拥有的高水量和保水量才能保障这一特性，这也是高分子吸水树脂能成为新一代尿裤芯片材料的主要原因。
We can find that there are two ingredients in the diaper chip: macromolecule water absorbent resin and wood pulp. A tree with high absorbent polymer water absorption and high water absorption quantity characteristics, water absorption and water retention and it is dozens of pulp and wood pulp, together with good dispersion effect of capillary, guide high water absorption rate, which is about 5-6 polymer water absorbent resin. Therefore, the performance of the two is complementary, and the suitable ratio and mixing of the diaper chips can achieve the best absorption rate and the effect of water absorption. If the rate is only concerned, the wood pulp will be the best raw material for the pants chip. We use diapers and promotion is the key to keep the baby's skin is dry, high water absorbent polymer resin with water retention and to guarantee this property, which is a water absorbent resin can become the main reason for the new generation of diaper material.
我们发现，初吸收速率较快的高分子吸水树脂在经过一非常短的时间后，吸收量就没有增长，这就产生了高分子聚合物胶凝阴隔的问题。高分子吸水树脂是一种颗粒表面经过一定程度交联的高分子聚合物。它在吸收液体的时候颗粒会快速膨胀同时机械强度下降，表面互相粘联和产生糊状的情况，如果表面互相粘联情况严重就会产生阴止液体透过已吸收并膨胀
We found that after a very short time, the absorption rate of polymer absorbent resin with higher initial absorption rate did not increase, resulting in the problem of polymer polymer gel septum. Polymer absorbent resin is a kind of polymer with a certain degree of crosslinking on the surface of particles. When it absorbs liquid, the particles will expand quickly, and the mechanical strength will decrease. The surface will stick to each other and produce paste. If the surface is attached to each other, the liquid will be absorbed and expanded.
