Usoro polishing nke plastik ebu

Mechanical polishing

Mechanical polishing bụ usoro polishing nke na-adabere na ịkpụ na nrụrụ plastik nke elu ihe ahụ iji wepụ akụkụ convex ndị a na-egbuke egbuke iji nweta elu dị larịị. N'ozuzu, a na-eji osisi nkume mmanụ, wiil ajị anụ, akwụkwọ aja, wdg, na ọrụ aka bụ isi ụzọ. Enwere ike iji akụkụ pụrụ iche dị ka elu nke ahụ na-atụgharị. Iji ngwaọrụ inyeaka dị ka turntables, ultra-nkenke polishing nwere ike iji maka ndị nwere elu elu mma chọrọ. Ultra-nkenke polishing bụ iji ngwá ọrụ abrasive pụrụ iche, nke a na-agbanye nke ọma n'elu ebe a na-arụ ọrụ nke ọma na mmiri na-egbuke egbuke nke nwere abrasives maka ntụgharị ọsọ ọsọ. N'iji teknụzụ a, enwere ike nweta oke ike nke Ra0.008μm, nke kachasị elu n'etiti ụzọ polishing dị iche iche. Igwe oghere anya na-ejikarị usoro a.

Chemical polishing

Chemical polishing bụ ime ka elu microscopic convex akụkụ nke ihe dị na kemịkal na-agbaze ọkachamma karịa akụkụ concave, iji nweta ire ụtọ elu. Isi uru nke usoro a bụ na ọ dịghị achọ ngwá ọrụ dị mgbagwoju anya, nwere ike ime ka ihe ndị na-arụ ọrụ na-eme ka ọ dị mgbagwoju anya, ma nwee ike na-ekpochapụ ọtụtụ workpieces n'otu oge, na-arụ ọrụ dị elu. Nsogbu bụ isi nke kemịkalụ polishing bụ nkwadebe nke mmiri mmiri na-egbuke egbuke. Ọdịdị elu nke a na-enweta site na nchacha kemịkalụ na-abụkarị 10 μm.

Electrolytic polishing

Ụkpụrụ bụ isi nke polishing electrolytic bụ otu ihe ahụ nke ịcha mmiri ozuzo, ya bụ, site n'ịhọpụta na-agbari obere protrusions n'elu ihe ahụ iji mee ka elu dị larịị. E jiri ya tụnyere kemịkalụ kemịkalụ, mmetụta nke mmeghachi omume cathode nwere ike iwepụ, mmetụta ya ka mma. The electrochemical polishing usoro na-ekewa ụzọ abụọ: (1) Macroscopic leveling The etisasịwo ngwaahịa na-agbasa n'ime electrolyte, na geometric roughness nke ihe elu na-ebelata, Ra> 1μm. ⑵ Ọkwa ọkụ dị ala: Anode polarization, nchapụta elu dị mma, Ra <1μm.

Ultrasonic polishing

Tinye workpiece na nkwusioru abrasive ma tinye ya na mpaghara ultrasonic, na-adabere na mmetụta oscillation nke ultrasonic, nke mere na abrasive na-agbanye ala ma na-egbuke egbuke n'elu ọrụ ahụ. Ultrasonic machining nwere obere ike macroscopic na agaghị eme ka nrụrụ nke workpiece, ma ọ na-esiri ike ịmepụta na ịwụnye ngwá ọrụ. Enwere ike ijikọta nhazi nke ultrasonic na usoro ọgwụ ma ọ bụ electrochemical. Na ndabere nke ngwọta corrosion na electrolysis, ultrasonic vibration na-etinye aka ịkpali ihe ngwọta, nke mere na etisasịwo ngwaahịa n'elu nke workpiece na-ekewapụ na corrosion ma ọ bụ electrolyte nso n'elu bụ edo; mmetụta cavitation nke ultrasonic na mmiri mmiri nwekwara ike igbochi usoro corrosion ma mee ka ọ dịkwuo elu.

Nchacha mmiri

Nchacha mmiri na-adabere na mmiri na-agba ọsọ dị elu yana ihe abrasive na-ebu ya iji sachaa elu nke workpiece iji nweta nzube nke polishing. Ụzọ ndị a na-ejikarị eme ihe bụ: nhazi ụgbọ elu abrasive, nhazi ụgbọ mmiri mmiri, igwe mmiri hydrodynamic na ihe ndị ọzọ. A na-eji nrụgide hydraulic na-egweri Hydrodynamic ka ọ na-eme ka mmiri mmiri na-ebu ihe abrasive na-aga azụ na gaba n'elu elu nke workpiece na oke ọsọ. A na-eme usoro ahụ nke ọma site na ogige pụrụ iche (ihe ndị dị ka ihe ndị dị na polymer) na-enwe mmetụta dị mma n'okpuru nrụgide dị ala ma jikọta ya na abrasives. Enwere ike iji silicon carbide ntụ ntụ mee abrasives.

Magnetik egweri na polishing

Nchacha abrasive magnetik bụ iji magnetik abrasives na-etolite brushes abrasive n'okpuru omume nke a magnetik na-egweri workpiece. Usoro a nwere nhazi nhazi dị elu, ịdị mma dị mma, njikwa dị mfe nke ọnọdụ nhazi na ọnọdụ ọrụ dị mma. N'iji abrasives kwesịrị ekwesị, nhụsianya elu nwere ike iru Ra0.1μm. 2 Mechanical polishing nke dabeere na usoro a, polishing ahụ a kpọtụrụ aha na nhazi nke ihe eji eme plastik dị nnọọ iche na ncha elu nke achọrọ na ụlọ ọrụ ndị ọzọ. N'ikwu ya n'ụzọ ziri ezi, polishing nke ebu kwesịrị ịkpọ nhazi mirror. Ọ bụghị naanị na ọ nwere nnukwu ihe achọrọ maka ịmecha onwe ya, kamakwa ọ nwere ụkpụrụ dị elu maka ịdị larịị elu, ịdị nro na izi ezi geometric. Nchacha elu na-achọkarị naanị elu na-egbuke egbuke. A na-ekewa ọkọlọtọ nke nhazi elu mirror n'ime ọkwa anọ: AO = Ra0.008μm, A1 = Ra0.016μm, A3 = Ra0.032μm, A4 = Ra0.063μm. Ọ na-esiri ike ịchịkwa nke ọma geometric ziri ezi nke akụkụ n'ihi ụzọ ndị dị ka polishing electrolytic na polishing mmiri. Otú ọ dị, elu àgwà nke kemịkalụ polishing, ultrasonic polishing, magnetik abrasive polishing na ụzọ ndị ọzọ na-adịghị ruo chọrọ, otú mirror nhazi nke nkenke ebu ka tumadi n'ibu polishing.
