脲醛膠Hh高分子防老劑；Foreign Name: Urea-Formaldehyde Glue Hh Polymeric Anti-aging Agent 不改變各膠種摩爾比配方，具有抑制脲醛膠反應(yīng)至終點(diǎn)放大分子量，延緩至測(cè)熱膠30秒不驟膠、降低游離醛氣味、縮短固化時(shí)間、提高熱壓成型車(chē)速，提高纖維含水率不爆板，提高內(nèi)結(jié)合強(qiáng)度、表結(jié)強(qiáng)度、改善吸厚性等優(yōu)異性能。It has the excellent properties such as inhibition of urea-formaldehyde glue reaction until end point, amplification of molecular weight, hot measurement glue without adhesion for 30s, reduction of free formaldehyde smell, shortening of curing time, increase of hot-pressing forming speed, improvement of fiber moisture without separation, and enhancement of internal bond strength, surface bond strength and thickness absorption, without changing the mole ration formula of various glues.

本產(chǎn)品是國(guó)際上能有效抑制和防止脲醛膠縮聚反應(yīng)過(guò)程中和儲(chǔ)存過(guò)程中樹(shù)脂老化現(xiàn)象的發(fā)生（延長(zhǎng)膠的儲(chǔ)存期在3-5個(gè)月內(nèi)不會(huì)喪失使用性能），其主要作用是抗熱氧老化、抗臭氧老化，并且對(duì)金屬離子、光和熱的防老化防護(hù)效果極為顯著。This product is the world’s unique new material that can inhibit and prevent the aging effect of urea-formaldehyde glues. It can effectively inhibit and prevent resin aging in the polycondensation reaction or storage process of urea-formaldehyde glue( to extend the storage life of the glue so that it will not loss its use performance within 3-5 months). Its primary functions are anti-heat and oxygen aging and antiozone aging. Moreover, it has very obvious anti-aging protective effects of metal ion, light and heat.

二、本產(chǎn)品外觀顏色淺黃色樹(shù)脂類(lèi)狀粉末狀，沸點(diǎn)88—95度。II. The product is light yellow resin power in appearance, with a boiling point of 88—95°。

三、應(yīng)用范圍;廣泛適用于E1級(jí)、E0級(jí)、P2級(jí)中（高）密度板、刨花板、膠合板、細(xì)木工板環(huán)保膠的生產(chǎn)

生產(chǎn)脲醛膠使用本產(chǎn)品時(shí),請(qǐng)膠廠技術(shù)人員在我方技術(shù)人員的指導(dǎo)下添加。
