Acrylic lehoakhoa: characterization le kopo

halogenated Acrylic ba sebediswa bakeng sa dipolasetiki, le polymeric dikatiso le lihlooho lona - ente lejoe, 'mabole lesela la acrylic, polymer, dikarolo, lesela la acrylic maiketsetso lejoe, lithaele litšoantšo,' mabole maiketsetso, ho eketsa kwahelang lintho tse bonahalang. Ba sebelisoa a tlhahisong ea bathtubs lesela la acrylic, liemahale, liliba, libeisine, bakeng sa sesebediswa sa polymer fuluru mokelikeli le coatings pente.

lehoakhoa Acrylic e sebediswa hammoho le poliester le epoxy halogenated. E tšoauoa ke palo e phahameng ea thatafatsa le toxicity fokolang haholo, leo e seng la epoxy le poliester halogenated. Ho sebetsa le boitsebiso boo o lokela ho fuwa motho thepa ya tshireletso (liatlana rabara, respirators, mese k'hothone apara, goggles sireletsang) le overalls. tshebetso yohle ha ho sebetsa le halogenated maiketsetso lokela ho phethahatsoa ka likamoreng tse hlomelloa le ventilation qobelletse batho. Tabeng ea ho kopana le lehoakhoa motsoako ka leihlong la tlameha ho o tletse ho hlatsoa ka metsi.

lehoakhoa Acrylic ka sebelisoa bobeli nosi le le fillers fapaneng. Sebopeho sa taba e botlaaseng karolo lona le moemeli phekole (phofo) - ho fihlela ho 3% ea boima ba 'mele palo yohle. Mocheso Optimum ka kamoreng bakeng sa molekyler ea lehoakhoa e lokela ho ba ka hodimo 15 ° C. Ha thempereichara e ka tlase 15 ° C, litsebi li nkhothaletsa ntlo ho eketsa motsoako ho 3,5% hardener. Re lokela ho hlokomela hore ha thempereichara e ka tlase 10 ° C le molekyler ya lintho tse bonahalang tse e ile ea eketseha ka makhetlo a 'maloa. Fuoa hore hardener ke mongobo haholo, pele ho sebelisa e ke ho hlokahala hore ho omella. Ho etsa sena, ho hlokahala hore ho apara ho se ka lakane e hloekileng ea pampiri le e ke e omella ka ho feletseng. E lokela ho a hopola hore e hardener metsi, ae fokotsang lebelo tshebetso molekyler, ea ho hlophisoa ka 'na ka boeona e fetola' mala. Hardener e bua ka lintho tse phatlohang, kahoo, ho bolokiloe le mongobo le hole radiators futhumatsang, khanya ea letsatsi ka ho toba (mahlaseli khanya).

lehoakhoa Acrylic e tšela ka e setshelo polasetiki (bakete, senoelo, sekotlolo, 'me joalo-joalo. D.), mor'a eo e ile eketsa hardener, joale motsoako ile ka ho feletseng ba hlohlelletsa ho fihlela shoa hoa feletseng tsa granules le (tse ka bang hlano metsotso e ka mocheso kamoreng). Motsoako sephetho le e ne e tletse ka tsa dibopeho tse hlokahalang. O ile a re pele ho lubricated foromo ho lokolloa mahlahana (karohano lacquers "Izokol", "Izolak" lithologic, kirisi kapa tse ling tse leha e le efe thepa e lubricious polasetiki). Ka mor'a hoo e ka bang 20-50 metsotso e (ho itšetlehile ka mocheso ambient) motsoako ile polymerized. Nakong molekyler e halefile (ho 60 ° C le esita le e phahameng), ho joalo e le ho qoba tukang, e sa kgothaletswa ka nako ya molekyler thetsana foromo matsoho. Feletseng thatafatsa etsahala ka letsatsi, ka nako e itseng ho itšetlehile ka mocheso ambient, sehlahisoa boima le bophahamo ba modumo.

Acrylic lehoakhoa le filler le: a mokhoa oa ho sebelisa

lehoakhoa e tsoakane le hardener ka, ka mor'a moo motsoako sephetho ile a phaella ka, manyolo le fillers inorganic. Ka dita filler sebediswa mabole, lejoe e sithabetseng, lehlabathe, lehlohlojane, joalo-joalo ... (tseo hangata More - mabole dita). E lokela ho a hopola hore bakeng sa lihlahisoa tsa 'mala o lokela ho kena ka ka mebala inert. All dikarolo tsa motsoako ba ka ho feletseng e tsoakiloeng, ka nako eo tletse ka liforomo tse loketseng. The karo-karolelano Optimum tsa lesela la acrylic lehoakhoa le filler - 30:70.

Maiketsetso lehoakhoa: a mokhoa oa ho boloka

lehoakhoa le lokela ho ho bolokoa ka tlung, e leng e sireletsoa bosa, UV bohato. Sehlooho ho melao ya polokelo a maiketsetso a bophelo lehoakhoa raka, athe e 1 selemo.
