順酐的應(yīng)用是怎樣的呢？下面我們從三個(gè)領(lǐng)域中進(jìn)行講解。

What is the application of maleic anhydride? Next, we will explain from three areas.

1.不飽和聚酯樹(shù)脂(UPR)

1. Unsaturated polyester resin (UPR)

不飽和聚酯樹(shù)脂(UPR)是我國(guó)順酐主要的消費(fèi)領(lǐng)城。不飽和聚酯樹(shù)脂是熱圓型樹(shù)脂的主要品種之一,由于其優(yōu)良的機(jī)械性能、電性能和耐化學(xué)腐蝕性能，且加工工藝簡(jiǎn)更,因此應(yīng)用廣泛。

Unsaturated polyester resin (UPR) is the main consumer of maleic anhydride in China. Unsaturated polyester resin is one of the main varieties of hot round resin. Because of its excellent mechanical properties, electrical properties and chemical corrosion resistance, and simple processing technology, it is widely used.

2.BDO、THF等加氫產(chǎn)品

2. Hydrogenation products such as BDO and THF

順酐酯化加氫可以生產(chǎn)1,4-丁二醇(BDO)、四氫呋喃(THF)等產(chǎn)品,這些有機(jī)和精細(xì)化工產(chǎn)品，在國(guó)內(nèi)較為緊俏,有著廣闊的應(yīng)用前。順酐在加氫類(lèi)產(chǎn)品(包括BDO、THF和CBL等)中的應(yīng)用，特別是在新型熱塑性工程塑料聚對(duì)萃二甲酸丁二醇面(PBT)和作為氨綸原料的聚四亞甲基醚二醇(PTMEC)中的應(yīng)用。

Maleic anhydride esterification and hydrogenation can produce 1,4-butanediol (BDO), tetrahydrofuran (THF) and other products. These organic and fine chemical products are in short supply in China and have broad application prospects. The application of maleic anhydride in hydrogenation products (including BDO, THF and Cbl, etc.), especially in new thermoplastic engineering plastics polybutylene terephthalate (PBT) and polytetramethylene ether glycol (ptmec) as raw material of spandex.

3.涂料方面

3. Coating

順酐在涂料方面的應(yīng)用主要是醇酸樹(shù)脂涂料和氨基樹(shù)脂涂料。醇酸樹(shù)脂涂料是18大類(lèi)除料中消費(fèi)量大的一類(lèi),產(chǎn)量和消費(fèi)量約占徐料總量的三分之一。醇酸樹(shù)脂具有良好的附著力、光澤度和抗腐蝕等性能,廣泛用于建筑涂裝、機(jī)械和汽車(chē)涂裝、家俱以及防腐涂裝；氨基樹(shù)脂涂料也有良好的硬度、光澤和保光保色性能，廣泛用于輕工家電產(chǎn)品的裝飾涂裝。

The application of maleic anhydride in coatings is mainly alkyd resin coatings and amino resin coatings. Alkyd resin coating is one of the 18 major types of materials, and its output and consumption account for about one third of the total amount of materials. Alkyd resin has good adhesion, gloss and corrosion resistance, and is widely used in building coating, machinery and automobile coating, furniture and anti-corrosion coating; Amino resin coatings also have good hardness, gloss and light and color retention properties, and are widely used for decorative coating of light industrial household appliances.

【用途】

[purpose]

重要的有機(jī)化工原料之一。廣泛應(yīng)用于生產(chǎn)醇酸樹(shù)脂、聚酯樹(shù)脂、農(nóng)藥、涂料、潤(rùn)滑油添加劑等產(chǎn)品。在農(nóng)藥、醫(yī)藥、涂料、油墨、潤(rùn)滑油添加劑、造紙化學(xué)品、紡織品整理劑、食品添加劑以及表面活性劑等領(lǐng)域得到廣泛的應(yīng)用，其加氫產(chǎn)物1，3-丁二醇（BDO）、γ-丁內(nèi)酯（GBL）、四氫呋喃（THF）、馬來(lái)酸、富馬酸和四氫酸酐是高附加值的基本有機(jī)化工原料,在石油加工、機(jī)械、軍工、農(nóng)藥、紡織和合成革等領(lǐng)域有廣泛的應(yīng)用,市場(chǎng)前景廣闊。

It is one of the important organic chemical raw materials. It is widely used in the production of alkyd resin, polyester resin, pesticides, coatings, lubricating oil additives and other products. It is widely used in the fields of pesticides, pharmaceuticals, coatings, inks, lubricating oil additives, papermaking chemicals, textile finishing agents, food additives and surfactants. Its hydrogenation products are 1,3-butanediol (BDO) γ- Butyrolactone (GBL), tetrahydrofuran (THF), maleic acid, fumaric acid and tetrahydro anhydride are basic organic chemical raw materials with high added value. They are widely used in petroleum processing, machinery, military industry, pesticides, textiles and synthetic leather, and have broad market prospects.

此外在包裝儲(chǔ)運(yùn)方面，氫氧化鉀廠(chǎng)家建議要用內(nèi)襯聚苯乙烯薄膜編織袋包裝,每袋凈重25kg.防止煙火、高溫、日曬、潮濕、猛烈撞擊、與皮膚接觸。遠(yuǎn)離火源、氧化劑、食品。儲(chǔ)存于通風(fēng)干燥處，期限三個(gè)月。包裝應(yīng)密封，有明顯“腐蝕性物品”標(biāo)志。更多相關(guān)內(nèi)容就來(lái)我們網(wǎng)站http://www.fahao168.com咨詢(xún)吧。

In addition, in terms of packaging, storage and transportation, the manufacturer of potassium hydroxide suggests that it should be packed in woven bags lined with polystyrene film, with a net weight of 25kg Prevent fireworks, high temperature, sunshine, humidity, violent impact and skin contact. Keep away from fire source, oxidant and food. Store in a ventilated and dry place for three months. The package shall be sealed and marked with "corrosive goods".
