Zosakaniza zazikulu ndi katundu wa pulasitiki
Mapulasitiki wamba onse amapangidwa kuchokera ku zinthu zachilengedwe monga mapadi, malasha, gasi, mchere ndi mafuta osapsa kudzera mu polymerization kapena polycondensation, ndipo zonsezi zimafunikira zopangira zenizeni.Mu polymerization reactor, ma monomers monga ethylene ndi propylene amalumikizidwa palimodzi kuti apange maunyolo aatali a polima.Polima iliyonse ili ndi zake, kapangidwe kake ndi kukula kwake kutengera mitundu yosiyanasiyana ya ma monomers oyambira omwe amagwiritsidwa ntchito.
Pali mitundu yambiri ya mapulasitiki, koma amatha kugawidwa m'magulu awiri akuluakulu a polima:
1.Thermoplastics (yomwe imafewetsa pakuwotha ndikuumitsanso pakuzizira).
2.Thermosets (omwe samafewetsa akapangidwa).
Ndi mautumiki ati omwe titha kupereka okhudza mapulasitiki
Mitundu ya jekeseni ya pulasitiki:
Kumangirira jakisoni ndi njira imodzi yomwe imagwiritsidwa ntchito kwambiri popangira zida zapulasitiki ndipo ndi mwala wapangodya wa luso la kupanga la RuiCheng.Jekeseni ndi kubaya chinthu chotenthetsera patani, chotchedwa nkhungu, chomwe chimazizira kukhala gawo limodzi lomwe ndi lapamwamba kwambiri, lamphamvu, komanso lotha kufanana.
Kumangirira jakisoni ndikobwerezabwereza, zomwe zimapangitsa kuti zikhale zabwino kusinthasintha kwamtundu komanso kudalirika kwa gawo.Izi zimapangitsanso jekeseni kuti ikhale yogwira mtima kwambiri komanso yotsika mtengo pakupanga voliyumu yayikulu.
ngati mutisankhe ngati ogulitsa mapulasitiki anu, titha kupereka mtengo wotsika mtengo kwambiri komanso mankhwala apamwamba kwambiri
Rapid jakisoni nkhungu:
Rapid jakisoni molding (RIM) ndi njira yopangira jakisoni yopangidwira kupanga timagulu tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono ta pulasitiki tokhala ndi nthawi yayifupi yotsogolera kuposa njira yopangira jakisoni.Nthawi zambiri, zida zomwe zimagwiritsidwa ntchito pa RIM ndi zofanana ndi zomwe zimagwiritsidwa ntchito popanga jakisoni wamba, kupatula kuti jekeseni wa RIM amapangidwa kuti azisintha mwachangu m'malo mokhazikika nthawi yayitali.
Kuchulukitsa:
Overmolding ndi njira yopangira jekeseni wamitundu yambiri pomwe zigawo ziwiri kapena zingapo zimawumbidwa pamwamba pa wina ndi mnzake.Overmolding nthawi zina amatchedwa kuumba awiri kuwombera chifukwa ndi njira ziwiri.
Choyamba, gawo loyambira (lomwe limadziwika kuti gawo lapansi) limapangidwa ndikuloledwa kuchiritsa.Magawo ochulukirapo nthawi zambiri amapangidwa ndi pulasitiki.Kenako, gawo lachiwiri limapangidwa mwachindunji pamwamba pa woyamba kuti apange chidutswa chimodzi cholimba.Overmolding imagwiritsidwa ntchito popanga zida zapulasitiki zomwe zimakhala ndi chogwirira cha mphira.Njira yowombera m'mano iwiri, mwachitsanzo, imakhala yopangira chogwirira chapulasitiki ndi mphira pamwamba (kupangitsa kuti mswachiwo usamaterera kuti ugwire).
Mtundu wamitundu iwiri:
Kumangira jekeseni wamitundu iwiri ndi njira yopangira yomwe imagwiritsidwa ntchito ponena za nkhungu ziwiri / mitundu iwiri kukhala gawo limodzi la pulasitiki, lomwe ndi luso lophatikiza zida ziwiri kapena mitundu iwiri yosiyana kukhala gawo limodzi lomaliza la pulasitiki pogwiritsa ntchito makina opangira jakisoni a 2k.
Kugwiritsa ntchito zigawo zapulasitiki
Mapulasitiki apamwamba ndi ofunikira pakupanga magalimoto.Pafupifupi mtundu uliwonse wagalimoto yamakono - kuyambira pachitetezo ndi magwiridwe antchito mpaka kuchita bwino komanso kukongola - zimadalira mapulasitiki ndipo, mochulukira, zida za polima kuti zikwaniritse zomwe ogula akuyembekezera.
Monga ogulitsa pulasitiki ku China, timasamalanso kugwiritsa ntchito pulasitiki m'mafakitale amagalimoto ndikuyang'ana pakupanga mapulasitiki apamwamba kwambiri.Zogulitsa zathu zimagulitsidwa kulikonse, makamaka ku Europe Slovakia ndi Romania.
Pakalipano pulasitiki yakhala ikugwiritsidwa ntchito kwambiri m'makampani amasewera, zida zambiri zamasewera zimapangidwa ndi plastic.such monga zida zamasewera Wheel, gudumu la tennis yotumikira makina.Kwa zida zamasewera izi nthawi zambiri timagwiritsa ntchito overmoulding kuteteza gawo lofunikira.Zigawo zapulasitiki zamasewera athu ndizodziwika kwambiri ku Brazil, ngati mukufuna kudziwa zambiri, chonde yang'anani nkhani yathu kapena zinthu zokhudzana ndi zida zapulasitiki zamasewera.
Pamlingo waukulu, mapulasitiki azachipatala amasiyana malinga ndi mawonekedwe ake.Chifukwa cha malamulo okhwima pazigawo zachipatala, mainjiniya athu amagwiritsa ntchito ma polima apulasitiki azachipatala pazinthu zinazaumoyo, kuyambira zida zopangira opaleshoni kupita kuchipatala.Pofuna kuonetsetsa kuti zigawo zapulasitiki zachipatalazi zikukwaniritsa zofunikira zachipatala, tinayesa zikwi zambiri.Tsopano mapulasitiki azachipatala awa omwe amagwiritsidwa ntchito popanga ma prototypes azachipatala amatha kupereka kukana koyenera, kuvala, kutentha, komanso dzimbiri.Nthawi yomweyo, zigawo za pulasitikizi zimatha kukhalabe ndi magwiridwe antchito apamwamba pambuyo potengera kutsekereza kobwerezabwereza kapena thupi.
Ubwino wa zigawo pulasitiki
➢ Kusinthasintha kwapangidwe kwapamwamba
➢ Zosiyanasiyana
➢ Mawonekedwe abwino kwambiri.
➢ Nthawi zopanga mwachangu
➢ Kubwerezabwereza kwakukulu ndi kulolerana
Ndi pulasitiki yanji yomwe timakonda kugwiritsa ntchito jakisoni
Kuti mudziwe zambiri za luso la jakisoni wa pulasitiki, muthakulumikizana ndi athugulu la malonda kuti mukambirane ntchito yanu yapadera.
