Lens ya Acrylic, PMMA ya plastike.

Intangiriro:

Isahani fatizo ya acrylic lens ikozwe muri PMMA, nayo bita lens ya acrylic lens kubantu bo muri Hong Kong na Tayiwani.Lens ya Acrylic yerekeza ku isahani ya acrylic.Kugirango ugere kuri optique ya optique, isahani yibanze izakora indorerwamo nyuma yo gutwikira vacuum.Lens ya plastike ikoreshwa mugusimbuza ibirahuri byikirahure, bifite ibyiza byuburemere bworoshye, ntibyoroshye kumeneka, kubumba no gutunganya byoroshye, amabara yoroshye nibindi, Umuvuduko witerambere uragenda wiyongera umunsi kumunsi, kandi byahindutse ubwoko bwikoranabuhanga mu gukora lens.Isahani ya plastiki irashobora gukorwa muburyo bukurikira: indorerwamo imwe, indorerwamo y'impande ebyiri, indorerwamo ya plastike, indorerwamo yimpapuro, lens igice, nibindi birashobora gukorwa ukurikije ibisabwa bitandukanye.Kurugero, ecran ya terefone igendanwa na TV irashobora kuboneka buri munsi.
Ibiranga lens:
Acrylic irakwiriye gutunganyirizwa mucyiciro cya kabiri, nko gutunganya, gushushanya ibintu bya termoplastike, guhuha, guhuha, guhuza ibicanwa, gucapa amashyanyarazi, gucapisha ecran na vacuum electroplating.Nyuma yo gutsinda, nibyo twita acrylic lens.

Isahani ya Acrylic ihindurwa na methyl methacrylate monomer (MMA), aribyo polymethylmethacrylate (PMMA) isahani ya plexiglass, ni ubwoko bwa plexiglass butunganywa nuburyo bwihariye.Ifite izina rya "Umwamikazi wa plastike".Ubushakashatsi niterambere rya acrylic bifite amateka yimyaka irenga 100.

Gukoresha lens:

Acrylic ifite ibyiza byuburemere bworoshye, igiciro gito kandi byoroshye.Uburyo bwayo bwo kubumba burimo guteramo, guterwa inshinge, gutunganya, acrike ya thermoforming, nibindi. Byumwihariko, kubumba inshinge birashobora gukorwa mubwinshi, hamwe nibikorwa byoroshye kandi bidahenze.Kubwibyo, ikoreshwa cyane mubice byibikoresho, amatara yimodoka, lensike optique, imiyoboro ibonerana nibindi.

Acrylic nigikoresho gishya cyiza cyo gukora ibikoresho byisuku nyuma yubutaka.Ugereranije nibikoresho bya ceramic gakondo, acrylic ntabwo ifite umucyo mwinshi utagereranywa gusa, ariko kandi ifite ibyiza bikurikira: gukomera kworoshye kandi ntibyoroshye kwangiza;Kugarura gukomeye, mugihe cyose ifuro ryoroshye ryinjijwe mu menyo yinyo irashobora guhanagura ibikoresho by isuku bishya.Imiterere iroroshye, kandi nta magufa akonje afite mu gihe cy'itumba;Amabara meza arashobora guhura numuntu kugiti cye.Ibase, ameza, ubwiherero nubwiherero bikozwe muri acrylic ntabwo ari byiza gusa muburyo, biramba, ariko kandi byangiza ibidukikije.Imirasire yacyo irasa nkiya magufa yabantu.Ibikoresho by'isuku ya Acrylic byagaragaye bwa mbere muri Amerika none bingana na 70% by'isoko mpuzamahanga.Bitewe ningorabahizi nigiciro kinini cyumusaruro wa acrylic, hariho isoko ryinshi risimbura make.Izi nsimburangingo, zizwi kandi nka "acrylic", mubyukuri ni ikibaho gisanzwe cyangwa ikibaho (nanone kizwi nka sandwich board).Ikibaho gisanzwe kijugunywa hamwe na plexiglass isanzwe ivunika hamwe na pigment.Ubuso bwacyo burakomeye kandi biroroshye gushira.Ingaruka zo gusya ni mbi nyuma yo gusya n'umucanga mwiza.Ikibaho kigizwe gusa nigice gito cya acrylic hejuru na plastike ya ABS hagati.Biroroshye gusibanganya bitewe ningaruka zo kwagura ubushyuhe no kugabanuka gukonje mukoresha.Acrylic yukuri nibinyoma irashobora kumenyekana uhereye kubutandukanya bwibara ryibara ryoroshye hamwe ningaruka zo gusya igice.1 Porogaramu yububiko: idirishya, inzugi zidafite amajwi n'amadirishya, igifuniko cyamanywa, akazu ka terefone, indorerwamo yamabara, nibindi. 4 Gusaba ubuvuzi: incubator yumwana, ibikoresho byubuvuzi bitandukanye byo kubaga, ibikoresho bya gisivili: ubukorikori, indorerwamo zo kwisiga, udusanduku, aquarium, indorerwamo zikinisha, nibindi. icyerekezo, acrile yerekana, nibindi

Ibiranga inzira:

1. Acrylic irimo methyl ya polar methyl, ifite hygroscopique igaragara.Kwinjiza amazi muri rusange ni 0.3% - 0.4%.Igomba kuba isahani ya acrylic mbere yo gukora
Igomba gukama kumiterere ya 80 ℃ - 85 ℃ kuri 4-5h.2. Acrylic ifite ibintu byiza kandi bigaragara bitari Newtonian fluid ibiranga ubushyuhe bwo gutunganya ibumba.Ubushuhe bwo gushonga buzagabanuka cyane hamwe no kwiyongera kwikigero cyogosha, kandi ibishishwa bya elegitoronike nabyo byumva cyane ihinduka ryubushyuhe.Kubwibyo, kubumba gutunganya polymethylmethacrylate, kongera umuvuduko wubushyuhe hamwe nubushuhe birashobora kugabanya cyane gushonga no kubona amazi meza.3. Ubushyuhe bwa acrylic butangira gutemba bugera kuri 160 ℃, kandi ubushyuhe butangiriraho kubora burenze 270 ℃, hamwe nubushyuhe bwagutse bwo gutunganya.4. Ubukonje bwa acrylic yashonga ni bwinshi, igipimo cyo gukonja kirihuta, kandi ibicuruzwa biroroshye kubyara ibibazo byimbere.Kubwibyo, uburyo bwimikorere bugenzurwa cyane mugihe cyo kubumba, kandi ibicuruzwa nabyo bikenera nyuma yo kuvurwa nyuma yo kubumba.5. Acrylic ni polymer ya amorphous ifite igabanuka rito hamwe nuburinganire bwayo, muri rusange hafi 0.5% - 0.8%, bifasha gukora ibice bya pulasitike bifite uburinganire buhanitse.6. Gukata Acrylic imikorere nibyiza cyane, kandi umwirondoro wacyo urashobora gukoreshwa muburyo butandukanye busabwa.

Ikoranabuhanga ryo gutunganya:

Acrylic irashobora gufata casting, gushushanya inshinge, gusohora, gutondagura, gushushanya laser, gukata lazeri nibindi bikorwa.

Gushushanya

Gushushanya ibishushanyo bikoreshwa mugukora imyirondoro nka plaque ya plaque na bar, ni ukuvuga, imyirondoro ikorwa na polymerisation nyinshi.Ibicuruzwa bikenerwa bikenera kuvurwa.Ibihe nyuma yubuvuzi ni ukubika ubushyuhe kuri 2h kuri 60 ℃ no kubika ubushyuhe kuri 2h kuri 120 ℃

Gutera inshinge

Gutera inshinge bifata ibikoresho bya granulaire byateguwe na polymerisation ihagarikwa, kandi kubumba bikorerwa kumashini isanzwe cyangwa imashini itera inshinge.Imbonerahamwe 1 irerekana uburyo busanzwe bwo guterwa inshinge za polymethylmethacrylate.Gutunganya ibipimo bya screw inshinge ya mashini ya plunger inshinge ya barrile ℃ ubushyuhe inyuma 180-200 180-200 hagati 190-230 imbere 180-210 210-240 ubushyuhe bwa nozzle ℃ 180-210 210-240 ubushyuhe bwubushyuhe ℃ 40-80 40-80 igitutu MPa 80-120 80-130 ifata igitutu MPa 40-60 40-60 screw umuvuduko rp.m-1 20-30 ibicuruzwa byo gutera inshinge nabyo bikenera nyuma yo kuvurwa kugirango bikureho ibibazo byimbere, Ubuvuzi bukorwa muri 70-80 ℃ gushyushya umwuka wumuyaga.Igihe cyo kuvura akrylic bar muri rusange gifata hafi 4H bitewe nubunini bwibicuruzwa.

Thermoforming

Thermoforming ninzira yo gukora isahani ya plexiglass cyangwa urupapuro mubicuruzwa bifite ubunini butandukanye.Gukata ubusa mubunini busabwa bifatanyirijwe kumurongo, bishyushye kugirango byoroshe, hanyuma bigashyirwaho igitutu kugirango bigere hafi yububiko kugirango ubone ishusho imwe nubuso.Nyuma yo gukonjesha no gushushanya, impande zogosorwa kugirango ubone ibicuruzwa.Uburyo bwo gushushanya vacuum cyangwa igitutu kiziguye cya punch hamwe numwirondoro birashobora gukoreshwa kugirango igitutu.Ubushyuhe bwa thermoforming burashobora kwerekeza ku bushyuhe bwubushyuhe busabwa mu mbonerahamwe ya 3. Iyo ukoresheje vacuum yihuse umushinga wo gukora ibicuruzwa, birakwiye gufata ubushyuhe hafi yurugero rwo hasi.Mugihe ukora ibicuruzwa byimbitse bifite imiterere igoye, birakwiye gufata ubushyuhe hafi yurugero rwo hejuru.Mubisanzwe, ubushyuhe busanzwe bwemewe.

Dufite ubunini bwose bwa Arylic lens, niba ubikeneye, nyamuneka twandikire, natwe dushobora gukora lens ya Arylic nkuko ubisabwa.Urashobora kohereza igishushanyo kuri twe, noneho, turashobora gukora ibishushanyo byawe.Murakoze cyane.
