A kind of automobile plastic production and processing burnishing device based on dustless technology
Technical field
The present invention relates to technical field of plastic, specially a kind of automobile plastic based on dustless technology, which produces and processes, to be used Burnishing device.
Background technique
Plastics are, by high-molecular compound made of addition polymerization or polycondensation polymerized, to be commonly called as plastics using monomer as raw material Or resin, it can freely change ingredient and body styles, by synthetic resin and filler, plasticizer, stabilizer, lubricant, colorant Equal additives composition.
The main component of plastics is resin.This noun of resin is initially the lipid secreted out of by animals and plants and gains the name, such as Rosin, shellac etc., resin refer to the high-molecular compound not yet with various additives mixing.Resin accounts for about plastics total weight 40%~100%.The basic performance of plastics depends mainly on the person's character of resin, but additive also plays an important role.Some plastics It is substantially made of, is free of or less containing additive, such as organic glass, polystyrene synthetic resin.
So-called plastics, it is one of synthetic resin in fact, and shape is similar with the pine resin in natural resin, by changing It is artificial synthesized to learn to do section progress, and is referred to as plastics.
Polishing machine is also referred to as grinder, is commonly used as mechanical polishing, polishing and waxing.Its working principle is that: motor Drive the sponge that is mounted on polishing machine or wool polishing disk high speed rotation, due to polishing disk and polishing agent collective effect and with to It throws surface to rub, and then can reach removal lacquer painting pollution, oxide layer, the purpose of shallow trace.The revolving speed of polishing disk generally exists 1500-3000r/min, mostly variable speed, when construction, can adjust at any time as needed.
The key of polishing machine operation is to try to obtain maximum polishing speed, to remove the damage generated when polishing as early as possible Hurt layer.Also polishing damage layer to be made to will not influence the tissue finally observed simultaneously, i.e., not will cause prosoplectenchyma.The former requires to make With thicker abrasive material, the damaging layer of polishing is removed to guarantee to have biggish polishing speed, but polishing damage layer is also relatively deep;The latter It is required that using most thin material, keep polishing damage layer shallower, but polishing speed is low.
Plastics can generate a large amount of plastic scrap in polishing is overweight, and the quality of these clasts is very light, it is easy to diffuse In workshop, is directly absorbed by worker by breathing, bring far-reaching influence to the health of worker.
