中文拼音 [fángbiànzhíjì]
防變質劑
英文
antidetereriorant-
According to the feature that deformation resulted from water absorption and mildew appear mainly on the rabbet surface of ccf, this paper adopts rsst to spray a special waterproof sealant on rabbet surface of ccf, so that the sealant can get into fiberboard to certain extent by means of capillarity and penetration, blockage the holes between fibers and capillary, cut up passage of water and change the properties of soakage and sorption to water in capillarity and fiber. at the same time, solidified sealant can form a compact waterproof pellicle on rabbet surface so as to prevent water and humidity from fiber ' s expansion and mildewing
針對吸水變形、霉變主要發生在地板企口表面的特徵，採用企口表面全封閉法，在復合強化地板企口表面噴塗特殊的防水封閉劑，使其依靠毛細管作用及滲透作用進入板內一定深度，堵塞木纖維之間的空隙及毛細孔通道，截斷水分傳遞的渠道，並改變毛細孔壁及纖維的表面性質以不利於水的浸潤與吸附，同時其固化后能在企口表面形成一層緻密的憎水薄膜，防止水分、濕氣從企口侵入板內引起木纖維膨脹變形、發霉等現象。Meanwhile, fundamental principles about electroless tin plating by reducing agent and disproportionation reaction were explained. function of every component in the bath was explained that complexing agent can effectively change the potential of copper and tin, and accelerate the beginning of replacement reaction favorably ; reducing agent can increase the rate of chemical reaction and has the effect of promoting reaction dynamics too ; antioxidant can effectively prevent sn2 + in the bath from being oxidated ; additive agent a can improve the stability of the bath ; additive agent b has such effects as refining and brightening for the tin deposits, and it enlarges the range of brightening section ; additive agent c used as leveling agent can not only make the depostis level off, but also improve the dispersive ability of the bath ; surface - active agent can solve bubble problem which gathered on the surface of the deposits, and improve the surface quality of the deposits and the bath stability
闡述了鍍液中各組分的作用：絡合劑能有效地改變銅、錫的電位，促使初期的置換反應順利進行；還原劑能加快化學反應速度，對反應動力學有積極的促進作用；抗氧化劑能有效地防止鍍液中sn ~ （ 2 + ）的氧化；添加劑a能提高鍍液的穩定性，添加劑b對鍍層能有細化和光亮作用，擴大了鍍層光亮區的范圍；添加劑c作為平滑劑，不僅能增強鍍層表面的平整性，而且能提高鍍液的分散能力；表面活性劑較好地解決了化學鍍過程中汽泡在鍍件表面聚集的問題，提高了鍍層的表面質量和鍍液的穩定性。To help fight corrosion, meguiar ' s can include anti - corrosion agents, which dramatically help to protect the surface from corrosive attack and deterioration
