Polymers exhibit diverse physical characteristics based on their molecular structure and composition, especially in relation to their glass transition temperature (Tg). Below the Tg, polymers are generally rigid and hard since the molecular chains have limited motion, essentially being in a glassy state. Above the Tg, they transition to a rubbery or soft state as the thermal energy allows for increased molecular mobility. However, the term "soft tacky" typically applies to behavior above Tg when the polymer exhibits viscoelastic properties. Below Tg, the limited molecular mobility due to low temperatures renders polymers more solid and less deformable rather than soft or tacky. This behavior can vary significantly across different polymer types, influenced by their chemical makeup and the presence of any plasticizers or fillers.
Sharpening resin, such as that used for crafts or casting, can be challenging due to its brittle nature. However, it is possible by using sandpaper or a rotary tool with sanding or grinding attachments. Start with a coarse grit to shape the resin, then progressively move to finer grits to smooth out the surface. For intricate details, manual sanding might be more effective, while a rotary tool can quickly handle larger areas. Throughout the process, wet sanding can help minimize dust and potentially improve the finish. After achieving the desired sharpness, polishing compounds can be applied to give the resin a glossy finish. Always wear protective gear, like a mask and goggles, to protect against resin dust.
Not all inkjet printers are bad. The reputation that inkjet printers have for being inferior is often due to their comparison with laser printers, particularly in terms of speed and cost-per-page. However, inkjet printers excel in areas such as photo printing, where they can produce high-quality, vibrant images that are superior to those from most laser printers. They are also capable of printing on a variety of media types, including glossy photo paper, textiles, and even CDs. The technology has evolved significantly, with manufacturers now offering models designed to address traditional concerns, such as high ink costs and slow print speeds. Some modern inkjet printers come with ink tank systems that drastically reduce the cost per page and are capable of high-speed printing. Therefore, while they may not be the best choice for every user or scenario—particularly those requiring large volumes of text printing—they are far from being universally "bad" and offer significant advantages in the right contexts.
