Mapulasitiki opangira zinthu m'magawo osiyanasiyana ogwiritsira ntchito

Pamene teknoloji ikupita patsogolo,mapulasitiki a engineeringpang'onopang'ono zakhala zofunikira kwambiri m'mafakitale osiyanasiyana pankhani ya sayansi yazinthu.Nkhaniyi ifotokoza za mawonekedwe, magulu, njira zopangira, komanso kagwiritsidwe ntchito ka mapulasitiki a engineering, kuwulula zachinsinsi za sayansi ya zinthuzi.

Concept and Characteristics of Engineering Plastics Engineering mapulasitiki ndi mapulasitiki ogwira ntchito kwambiri okhala ndi makina abwino kwambiri, kukhazikika kwa mankhwala, komanso kukana kutentha kwambiri.Poyerekeza ndi mapulasitiki wamba, amawonetsa mphamvu zapamwamba, kulimba, komanso kukana kutentha, zomwe zimawapangitsa kuti aziwoneka bwino m'magawo osiyanasiyana aukadaulo.

Gulu la Engineering Plastics

Mapulasitiki ogwira ntchito kwambiri: monga polyamide (PAI) ndi polyetheretherketone (PEEK), omwe amadziwika chifukwa cha kukhazikika kwawo kwa kutentha kwambiri komanso mphamvu, amagwiritsidwa ntchito kwambiri muzamlengalenga, magalimoto, ndi mafakitale ena.
Engineering thermoplastics: monga polystyrene (PS) ndipolycarbonate (PC), yokhala ndi kukonza bwino komanso magwiridwe antchito, omwe amagwiritsidwa ntchito kwambiri pazamagetsi, zamankhwala, ndi zina.
Mapulasitiki opangira thermosetting: kuphatikiza ma epoxy resins ndi phenolic resins, omwe amadziwika chifukwa cha makina awo abwino kwambiri komanso kukana kutentha kwambiri, omwe amagwiritsidwa ntchito kwambiri pazida zamagetsi ndi zida zamagalimoto.
Engineering elastomers: mongapolyurethane (PU)ndi ma thermoplastic elastomers (TPE), omwe amayamikiridwa chifukwa cha kukhazikika kwawo bwino komanso kukana kuvala, amagwiritsidwa ntchito kwambiri m'minda yamagalimoto ndi zida zamasewera.
Kupanga Mapulasitiki Opanga Mapulastiki Kupanga mapulasitiki auinjiniya nthawi zambiri kumaphatikizapo kukonza zakuthupi, kutentha ndi kusungunuka, ndi kutulutsa kapena jekeseni.Kupanga mapulasitiki apamwamba kwambiri ndizovuta kwambiri, zomwe zimafuna kuwongolera mwamphamvu ndi zida zapamwamba.Zatsopano zomwe zikupitilira pakupanga zikukhudza mwachindunji magwiridwe antchito ndi mtundu wa zinthu zamapulasitiki zauinjiniya.

Kugwiritsa Ntchito Pulasitiki Waumisiri M'magawo Osiyanasiyana

Zamlengalenga: Mapulasitiki aumisiri amagwira ntchito yofunika kwambiri muzamlengalenga, ndipo PEEK ya pulasitiki yogwira ntchito kwambiri imagwiritsidwa ntchito popanga zida za injini za ndege, zomwe zimawonjezera kutentha kwawo komanso kukana dzimbiri.

Kupanga magalimoto: Mapulasitiki a uinjiniya amagwiritsidwa ntchito kwambiri popanga magalimoto, kuchokera kuzinthu zamkati mpaka kumakina a injini, monga PC ndi PA, amachepetsa kwambiri kulemera kwagalimoto ndikuwongolera mafuta.

Zamagetsi ndi magetsi: Mapulasitiki aumisiri amagwira ntchito yofunika kwambiri pazida zamagetsi ndi zamagetsi, kupereka zotsekereza, kukana moto, ndi ntchito zina.Pulasitiki ngati PC ndi PBT amagwiritsidwa ntchito kwambiri m'nyumba zamagetsi ndi zolumikizira.
Kupanga zida zamankhwala: The biocompatibility ya mapulasitiki aumisiri amawapangitsa kukhala chisankho chabwino pakupanga zida zamankhwala.Mwachitsanzo, polycarbonate (PC) imagwiritsidwa ntchito popanga zida zachipatala zowonekera komanso zolimba.

Zomangamanga: Kugwiritsa ntchito mapulasitiki a uinjiniya mu uinjiniya womanga makamaka kumayang'ana kwambiri kukana kwanyengo, kukana dzimbiri, ndi zina.Pulasitiki ngati PVC ndi PA amagwiritsidwa ntchito mu mapaipi, zida zotsekera, ndi zina zambiri.
Future Development Trends of Engineering Plastics

Chitukuko chokhazikika: Kukula kwamtsogolo kwa mapulasitiki auinjiniya kudzagogomezera kukhazikika, kuphatikiza kuwongolera magwiridwe antchito komanso kufufuza momwe angagwiritsidwire ntchito kuti achepetse kuwonongeka kwa chilengedwe.

Kuchita bwino: Ndi kupita patsogolo kwaukadaulo, mapulasitiki auinjiniya aziyang'ana kwambiri pakuwongolera kutentha kwapamwamba, mphamvu, ndi zinthu zina kuti zikwaniritse zofunikira zaukadaulo.

Kugwiritsa ntchito mwanzeru: Mapulasitiki aumisiri akuyembekezeka kutenga gawo lalikulu pakugwiritsa ntchito mwanzeru mtsogolomo, monga kupanga mapulasitiki aukadaulo anzeru okhala ndi ntchito zowunikira kuti aziwunika momwe thanzi lawo lilili.

Kuphatikiza apo, mapulasitiki opangira uinjiniya amagwiritsidwa ntchitoconveyor odzigudubuza(Mphamvu yokoka wodzigudubuza） akuphatikizapo polyethylene (PE), polypropylene (PP), ndi nayiloni (PA), pakati pa ena.Poyerekeza ndi chikhalidweodzigudubuza zitsulo,  odzigudubuza apulasitiki kukhala zosiyana izi:

Kulemera kwake:Zodzigudubuza zapulasitikindi zopepuka kuposaodzigudubuza zitsulo, zomwe zimathandizira kuchepetsa kulemera kwa ma conveyor, kugwiritsa ntchito mphamvu, komanso kuyendetsa bwino ntchito.

Kukana kuvala: Zodzigudubuza za pulasitiki nthawi zambiri zimakhala ndi kukana kwabwino, kuchepetsa mikangano ndilamba wa conveyorndi kutalikitsa moyo wawo.

Kukana kwa dzimbiri: Zida zamapulasitiki zauinjiniya zili ndi kukana kwa dzimbiri, koyenera kugwiritsidwa ntchito m'malo achinyezi kapena owononga.

Kukhazikika: Zida za pulasitiki zodzigudubuza zitha kubwezeretsedwanso ndikugwiritsidwanso ntchito, zogwirizana ndi mfundo zachitukuko chokhazikika komanso kupindulitsa chilengedwe.

Kuchepetsa phokoso: Zodzigudubuza za pulasitiki nthawi zambiri zimakhala ndi mayamwidwe abwino komanso zochepetsera phokoso, zomwe zimapangitsa kuti chotengeracho chitonthozedwe.

Ndikofunikira kusankha zinthu zodzigudubuza zoyenera kutengera momwe zimagwiritsidwira ntchito komanso zofunikira kuti zitsimikizire kukhazikika komanso kuchita bwino kwakachitidwe ka conveyor.

Monga otsogola pazasayansi yazinthu, kufalikira kwa mapulasitiki aukadaulo m'mafakitale osiyanasiyana kumatsimikizira gawo lawo laukadaulo wamakono.Popeza ukadaulo ukupita patsogolo nthawi zonse, mapulasitiki aumisiri ali okonzeka kukhala ndi malo okulirapo, opereka mayankho odalirika komanso ochita bwino kwambiri pama projekiti a uinjiniya m'magawo onse.
