Lignin begins to degrade and change its structure at around 160-220°C (320-428°F), but it does not have a clear melting point like some other polymers.
Yes, fiberglass resin can melt styrofoam. The chemicals in fiberglass resin can dissolve and degrade the styrofoam, causing it to melt or weaken. It's important to avoid direct contact between fiberglass resin and styrofoam when working on projects.
It is possible to melt gold at home using a torch or a kiln that reaches high temperatures. However, you should take safety precautions, such as wearing protective gear and working in a well-ventilated area, as melting gold involves working with extreme heat. It is advisable to have some experience or seek guidance from a professional before attempting to melt gold at home.
Mixing and melting are related in that both processes involve changes in the state or arrangement of matter. Mixing typically involves combining two or more substances, which may or may not change their physical states, while melting specifically refers to the transition of a solid into a liquid when heated. In some cases, mixing can occur during melting, such as when a solid dissolves in a liquid or when different solid substances are blended as they melt. Both processes illustrate the principles of thermodynamics and molecular interactions.
During hot melt extrusion, the active pharmaceutical ingredient and the polymers are heated about their class Tg or Tm. Screws are then fed into them for mixing purposes. If then quickly cools to form a glass.
Melt spinning is used for polymers that can be melted i.e. the polymers must have a melting temperature (thermoplastic polymers). Dry spinning is used for polymers that do no have melting temperature and need to be dissolved in solvent (thermoset polymers). In case of melt spinning, the polymer solidifies by cooling after being extruded from the spinneret. Whereas, in case of dry spinning, the polymer solidifies through evaporation of solvents and this is achieved by a stream of air or inert gas.
it is something that you melt
to become liquefied by warmth
The root word "fusio" is derived from the Latin word "fundere," meaning "to pour" or "to melt." It is commonly used in English to denote a blending or mixing together of different elements, as seen in words such as fusion, confuse, and diffuse.
Well, honey, if you want to make a solid solution, you usually have to mix and melt substances together to get them all cozy and combined. Crushing might help speed up the process by increasing the surface area for mixing, but it's not always necessary. So, in short, yes, you typically need to crush, mix, and melt substances to make a solid solution, but there can be exceptions depending on the specific materials you're working with.
The value of Tg depends heavily on the mobility of the polymer chain, and for most synthetic polymers lies between 170°K and 500°K (-103°C and 227°C). Pure crystalline polymers do not have a glass transition temperature because the glass transition temperature is only applicable to amorphous polymers.

Hot melt powder is typically made by mixing thermoplastic resins, wax, and other additives to create a fine powder. This powder can then be applied to surfaces and melted to form a bond. The exact formulation and process can vary depending on the desired properties of the hot melt powder.
Lignin begins to degrade and change its structure at around 160-220°C (320-428°F), but it does not have a clear melting point like some other polymers.
No. If a rock melts and then re-solidifies, then by definition the resulting rock is igneous.
Trust me, You'll know when a volcano is working as soon as your cloths start to melt to your skin.
