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.
