　　超純水制備專用混床樹脂 UPWM-100

　　Physical and chemical properties:

　　UPWM-100型超純水專用精處理混床樹脂系采用國際上先進(jìn)的核子級(jí)樹脂制造工藝，采用高純?cè)噭┙?jīng)多道嚴(yán)格工序嚴(yán)格精制而得的一種超純混床樹脂（拋光樹脂）。適合在以RO、EDI為前置處理設(shè)備的超純水系統(tǒng)中作為終端精制混床制取超純水。廣泛應(yīng)用于電子行業(yè)半導(dǎo)體材料生產(chǎn)；實(shí)驗(yàn)室、醫(yī)院等各型超純水機(jī)；以及核電站含放射性物質(zhì)的水處理系統(tǒng)等領(lǐng)域。具有產(chǎn)品純度高、運(yùn)行周期長、出水水質(zhì)穩(wěn)定等特點(diǎn)。當(dāng)進(jìn)水水質(zhì)＞16.5MΩ.cm時(shí)，出水水質(zhì)可達(dá)18MΩ.cm以上。在合成該樹脂混合物時(shí)，H+型和OH-型轉(zhuǎn)型率很高。長時(shí)間在空氣中暴露會(huì)吸收大量二氧化碳，從而影響產(chǎn)品的性能及使用。因此一旦開包需盡快使用，不用的部分須仔細(xì)密封。另外，該產(chǎn)品不可受到陽光直接照射或曝曬。該產(chǎn)品無需在交換柱中注水，直接裝填避免二次分層。
　　UPWM-100-type ultra-pure water special polishing mixed bed resin system adopts international advanced nuclear grade resin manufacturing process, the use of high purity reagents through many strict procedure is strictly a refining derived ultrapure mixed bed resin (polished resin). Suitable for terminal refined mixed bed in the pre-treatment equipment, RO, EDI ultrapure water system as the preparation of ultra-pure water. Widely used in the electronics industry production of semiconductor materials; laboratories, hospitals and other ultra-pure water; containing radioactive substances as well as nuclear power plants, water treatment systems and other fields. With high purity, long operation cycle, water quality and stability. > 16.5MΩ.cm when water quality, water quality up to more than 18MΩ.cm. Mixture of synthetic resin, H +-type and OH-type transition rate is very high. Long exposed to air will absorb large amounts of carbon dioxide, thus affecting the performance and the use of the product. Once open the package as soon as possible, not required to be carefully sealed. In addition, the product is not subject to direct sunlight or exposure. The product does not need to be in the exchange columns with water, directly filled avoid secondary stratification.
