Epoxy

Epoxy adalah suatu kopolimer, terbentuk dari dua bahan kimia yang berbeda. Ini disebut sebagai "resin" dan "pengeras". Resin ini terdiri dari monomer atau polimer rantai pendek dengan kelompok epoksida di kedua ujung. Epoxy resin Paling umum yang dihasilkan dari reaksi antara epiklorohidrin dan bisphenol-A, meskipun yang terakhir mungkin akan digantikan dengan bahan kimia yang serupa. Pengeras terdiri dari monomer polyamine, misalnya Triethylenetetramine (Teta). Ketika senyawa ini dicampur bersama, kelompok amina bereaksi dengan kelompok epoksida untuk membentuk ikatan kovalen. Setiap kelompok NH dapat bereaksi dengan kelompok epoksida, sehingga polimer yang dihasilkan sangat silang, dan dengan demikian kaku dan kuat. Proses polimerisasi disebut "curing", dan dapat dikontrol melalui suhu, pilihan senyawa resin dan pengeras, dan rasio kata senyawanya; proses dapat mengambil menit untuk jam. Beberapa formulasi manfaat dari pemanasan selama masa penyembuhan, sedangkan yang lainnya hanya memerlukan waktu, dan suhu ambien.

abrasive

An abrasive is a material, often a mineral, that is used to shape or finish a workpiece through rubbing which leads to part of the workpiece being worn away. While finishing a material often means polishing it to gain a smooth, reflective surface it can also involve roughening as in satin, matte or beaded finishes.
Abrasives are extremely commonplace and are used very extensively in a wide variety of industrial, domestic, and technological applications. This gives rise to a large variation in the physical and chemical composition of abrasives as well as the shape of the abrasive. Common uses for abrasives include grinding, polishing, buffing, honing, cutting, drilling, sharpening, lapping, and sanding (see abrasive machining). (For simplicity, "mineral" in this article will be used loosely to refer to both minerals and mineral-like substances whether man-made or not.)
Files act by abrasion but are not classed as abrasives as they are a shaped bar of metal. However, diamond files are a form of coated abrasive (as they are metal rods coated with diamond powder).

Korosi

Korosi (corrosion) atau karat sebenarnya adalah gejala kebalikan dari proses produksi besi dari bijihnya. Bila membuat besi dari bijih besi memerlukan usaha yang sangat sulit, tetapi pada proses korosi justru sebaliknya. Bahan korosif malah akan dengan sangat mudah tergerus habis dan kembali menjadi bijih agar bisa menyatu dengan alam.

Sandblasting

Sandblasting is a general term used to describe the act of propelling very fine bits of material at high-velocity to clean or etch a surface. Sand used to be the most commonly used material, but since the lung disease silicosis is caused by extended inhalation of the dust created by sand, other materials are now used in its place. Any small, relatively uniform particles will work, such as steel grit, copper slag, walnut shells, powdered abrasives, even bits of coconut shell. Due to the dangers of inhaling dust during the process, sandblasting is carefully controlled, using an alternate air supply, protective wear, and proper ventilation.
