3. Litšobotsi tsa ts'ebetso ea PMMA
Litlhoko tsa ts'ebetso ea PMMA li thata. E tsotella haholo mongobo le mocheso. E tlameha ho omisoa ka botlalo pele e sebetsoa. The melt viscosity ea eona e batla e phahame, kahoo e hloka ho bōptjoa ka mocheso o phahameng (219 ~ 240 ℃) le khatello. Mocheso oa hlobo o pakeng tsa 65 ~ 80 ℃ o betere. Ho tsitsa ha mocheso oa PMMA ha ho molemo haholo. E tla fokotsoa ke mocheso o phahameng kapa ho lula mocheso o phahameng nako e telele haholo. Lebelo la sekoti ha lea lokela ho ba holimo haholo (hoo e ka bang 60rpm), kaha ho bonolo ho etsahala likarolong tse teteaneng tsa PMMA. Ketsahalo ea "void" e hloka liheke tse kholo le "mocheso o phahameng oa thepa, mocheso o phahameng oa hlobo, lebelo le liehang" ho sebetsa maemo a ente.
4. acrylic (PMMA) ke eng?
Acrylic (PMMA) ke polasetiki e hlakileng, e thata e atisang ho sebelisoa sebakeng sa likhalase lihlahisoa tse kang lifensetere tse sa keneng, matšoao a bonesitsoeng, skylights le li-canopies tsa lifofane. PMMA ke ea lelapa la bohlokoa la li-resin tsa acrylic. Lebitso la lik'hemik'hale la acrylic ke polymethyl methacrylate (PMMA), e leng resin ea maiketsetso e entsoeng ka polymerized ho tloha methyl methacrylate.
Polymethylmethacrylate (PMMA) e boetse e tsejoa e le acrylic, acrylic glass, 'me e fumaneha tlas'a mabitso a khoebo le lihlahisoa tse kang Crylux, Plexiglas, Acrylite, Perclax, Astariglas, Lucite, le Perspex, har'a tse ling. Polymethylmethacrylate (PMMA) e atisa ho sebelisoa ka mokhoa oa lakane e le mokhoa o bobebe kapa oa shatterproof ho fapana le khalase. PMMA e boetse e sebelisoa e le resin ea ho lahla, enke le ho roala. PMMA ke karolo ea sehlopha sa lisebelisoa tsa polasetiki tsa boenjiniere.
5. acrylic e entsoe joang?
Polymethyl methacrylate e entsoe ka polymerization kaha ke e 'ngoe ea li-polymers tsa maiketsetso. Ntlha ea pele, methyl methacrylate e kenngoa ka har'a hlobo 'me ho eketsoa motsoako ho potlakisa ts'ebetso. Ka lebaka la ts'ebetso ena ea polymerization, PMMA e ka etsoa ka mefuta e fapaneng joalo ka maqephe, li-resin, li-blocks le lifaha. Acrylic glue e ka boela ea thusa ho nolofatsa likotoana tsa PMMA le ho li kopanya hammoho.
PMMA e bonolo ho e laola ka mekhoa e fapaneng. E ka kopanngoa le lisebelisoa tse ling ho thusa ho ntlafatsa thepa ea eona. Ka thermoforming, e fetoha habonolo ha e futhumala mme e tiisa ha e pholile. E ka ba boholo bo loketseng ho sebelisa sakha kapa laser cutting. Haeba e bentšitsoe, o ka tlosa li-scratches ho tloha holimo mme oa thusa ho boloka botšepehi ba eona.
6. Mefuta e fapaneng ea acrylic ke efe?
Mefuta e 'meli e meholo ea polasetiki ea acrylic e entsoe ka acrylic le extruded acrylic. Cast acrylic e theko e boima haholo ho e hlahisa empa e na le matla a betere, ho tšoarella, ho hlaka, mefuta ea thermoforming le botsitso ho feta acrylic e extruded. Cast acrylic e fana ka khanyetso e ntle ea lik'hemik'hale le ho tšoarella nako e telele, 'me e bonolo ho e mebala le ho e etsa nakong ea ts'ebetso ea tlhahiso. Cast acrylic e fumaneha ka mefuta e fapaneng ea botenya. Acrylic e ekelitsoeng e na le chelete e ngata ho feta acrylic e entsoeng ka tšepe 'me e fana ka acrylic e tsitsitseng haholoanyane, e sebetsang ho feta acrylic e entsoeng (ka litšenyehelo tsa matla a fokotsehileng). Extruded acrylic e bonolo ho sebetsa le mochine, e leng se etsang hore e be mokhoa o babatsehang oa ho sebelisa likhalase tsa likhalase lits'ebetsong.
7. Ke hobane'ng ha acrylic e sebelisoa hangata?
Acrylic e atisa ho sebelisoa hobane e na le litšobotsi tse tšoanang tse molemo joaloka khalase, empa ntle le mathata a brittleness. Khalase ea Acrylic e na le thepa e ntle ea optical mme e na le index e ts'oanang ea refractive joalo ka khalase sebakeng se tiileng. Ka lebaka la thepa ea eona e ke keng ea senyeha, baqapi ba ka sebelisa li-acrylics libakeng tseo ho tsona khalase e ka bang kotsi haholo kapa e neng e ka hlōleha (joaloka li-periscopes tse tsamaeang ka tlas'a metsi, lifensetere tsa lifofane, joalo-joalo). Ka mohlala, mofuta o tloaelehileng ka ho fetisisa oa khalase e thibelang likulo ke sekotoana sa acrylic sa 1/4-inch-thick, se bitsoang solid acrylic. Acrylic e boetse e sebetsa hantle ha ho etsoa ente 'me e ka etsoa hoo e batlang e le sebopeho leha e le sefe seo moetsi oa hlobo a ka se etsang. Matla a khalase ea acrylic e kopantsoeng le boiketlo ba eona ba ho sebetsa le ho etsa mechine e etsa hore e be thepa e babatsehang, e hlalosang hore na ke hobane'ng ha e sebelisoa haholo indastering ea bareki le ea khoebo.
