Bleed out

Plasticizers are relatively nonvolatile liquids which are blended with polymers to alter their properties by intrusion between polymer chains. Diisooctyl phthalate is a common plasticizer. A plasticizer must be compatible with the polymer to avoid bleeding out over long periods of time. Products containing plasticizers tend to be more flexible and workable. 

The oxidation-resistant SiC fiber was prepared from polycarbosilane containing Zr(OC4H9)4 by the same process as that used for the aforementioned tita-nia/silica fiber, except that the calcination was performed in Ar atmosphere at 1400 °C. In this case, the polycarbosilane and Zr(OC4H9)4 were effectively converted into SiC-based bulk ceramic and zirconium oxide (cubic zirconia). Before the conversion, bleed-out of the zirconium compound proceeded effectively. AES depth analysis of the fiber surface showed an increase in the concentration of zirconium towards the surface. This construction was confirmed by the TEM image of the cross-section near the fiber surface. This indicates the direct production of a SiC-based fiber covered with a Zr02 surface layer, which... 

During casting of small ingots, one developed a leak (bleed-out) and contacted water near an unpainted (slightly rusty) steel plate. An explosion resulted...

A vessel holding about 0.14 m of water was contacted with molten aluminum during a bleed-out from an ingot. An explosion took place... 

Still, these coatings are far from ideal and are not yet sufficiently stable for technical application. Their reoxidation is strongly hindered, necessitating a relatively high overpotential of several hundreds of millivolts and their stability is insufficient, with chromium bleeding out as chromate. Yet the results obtained by the method that allows fixing with an easily applicable method a soluble redox mediator to an oxidic anode is encouraging. The an-...

Penetrant Method. This method does not depend upon radiation interactions with the lest object and is essentially noninstrumental. A special penetrant substance is applied freely on the test object and allowed to work into tight cracks. See Fig. 3. The penetrant is removed from all surface areas and the piece is sprayed with a developer. The developer dries to an even white coating, while the penetrant bleeds up from any flaws through the developer, forming bright-red or fluorescent indications on the white surface. The size of the defect is indicated by the richness of color, speed of bleed-out, and dimensions ohserved. 

Among metal-complex dyes only the planar 1 1 copper complexes exhibit sufficient substantivity to dye paper, whereas the octahedral 1 2 chromium and cobalt complexes are unsuitable for this purpose. Cationic substantive dyes, such as the bis-copper complex 26 [45] provide the most colorless effluent waters and superior fast paper dyeings that do not bleed out upon contact with milk, fruit juice, or alcohol [46],... 

Owing to the low molecular weight of DN its immobilization on a particulate carrier, before inclusion in alginate, was necessary, in order to prevent enzyme bleeding out of the alginate matrix [106, 107]. 

In a properly designed tool run under the proper process conditions, the gas with its much lower viscosity than the melt remains isolated in the gas channels of the part without bleeding out into any thin-walled areas in the mold. The gas produces a balloon-like pressure on the melt. 

Traditionally, a low-molecular-weight liquid plasticiser addition method has been used for achieving flexible PLA films. However, the film made with this method was found to be unstable against changes in external factors such as temperature and pressure, resulting in the bleeding out of the liquid plasticiser, which in turn would lead to defects in the film characteristics such as transparency and flexibility, which were altered over time. 

Toray Industries has developed a new technology that has succeeded in containing the occurrence of bleeding out when faced with changes in temperature or pressure and displays highly stable flexibility while not losing any of the superior features of PLA such as transparency, heat resistance, and biodegradability. 

Materials have been mixed with a high-speed mixer, entrapping air in the resin. After the surface has been troweled in place and finished, air bleeds out as blisters or tiny bubbles. A paddle mixer moving at more than 350 rpm can cause this. 

Exudation or Bleed-Out Freedom from exudation or bleed-out of the IMR agent in the molded article is also be a critical factor to overall performance. 

Faint adhesion although a factor of wet-out, Is also controlled by solvent "bite", and post molded freedom from IMR exudation or bleed out, a topic previously reviewed. Obviously, the selection of a solvent system for a paint formulation must be properly addressed In order to eliminate, or, at the very least, minimize this type of paint adhesion deficiency. Some of this topic Is further discussed under the section titled Theoretical Cons lderatlons. 

Notice the vent at the top of the shell-side of the HX. Usually a very small fraction of the steam flow is allowed to bleed out of the shell. This is done to allow air which is often mixed with the steam to escape. Otherwise non-condensable gases will accumulate in the shell, causing the pressure to rise and decreasing the steam flowrate.
