Kupanga pulasitiki
Pulasitiki - Mawuwa amachokera ku Chigriki (plastikos), kutanthauza kuti yoyenera kuumba, ndiko kuti, pulasitiki pakupanga, kuwalola kuti aponyedwe.
Pangani mawonekedwe osiyanasiyana. Kupangidwa kwa pulasitiki kumatha kutchedwa mbambande ya anthu m'zaka za zana la 20, patatha zaka zoposa 100 za chitukuko, pulasitiki yakhala paliponse.
Paxsing
"Paksin" anali woyamba kupezeka - pulasitiki kukula. M'zaka za m'ma 1850, katswiri wa zamankhwala wachingelezi Parkes anali kufufuza njira zopangira ma collodion, mwangozi anasakaniza collodion ndi camphor, kupanga a. Zinthu zolimba zomwe zimatha kupindika. Ndipo adayitcha 'Paksin'. Kugwiritsa ntchito mapaki "Paxine" adapanga chilichonse kuyambira zisa mpaka mabatani mpaka zodzikongoletsera, ndipo anthu adazikonda.
celluloid
M'zaka za m'ma 1860, Hiatt anakonza njira yopangira "Paksin" ndikuyitcha "Celluloid". "Ceruloc poyambirira idagwiritsidwa ntchito popanga mipira ya mabiliyoni, koma pamene msika wapulasitiki udapitilira kukula, "Ceruloc" idapangidwa kukhala mitundu yosiyanasiyana.
Zogulitsa. "Celluloid" ndi pulasitiki yopangidwa ndi anthu, yokhala ndi mawonekedwe oyaka, kotero kuti kupanga kwake kumakhala kochepa.
Kupangidwa kwa polyethylene
Mu 1933, Reginald Gibson ndi Eric Fawcett wa ICI adapeza kuti ethylene ikhoza kupangidwa ndi polyethylene pansi pa kupanikizika kwakukulu.Njirayi inkadziwika kuti njira yothamanga kwambiri, ndipo kupanga mafakitale kunayamba mu 1939. Polyethylene (PE) kenako inasintha kukhala yotsika polyethylene (LDPE) ndi polyethylene yapamwamba kwambiri (HDPE) m'mitundu iwiri. Kumayambiriro kwa zaka za m'ma 1950, American Phillips Oil Company inapeza chromium oxideMonga chothandizira, ethylene ikhoza kupangidwa ndi polyethylene kuti ipange polyethylene yochuluka kwambiri, ndipo kupanga mafakitale kunakwaniritsidwa mu 1957. M'ma 60s, kampani ya ku Canada ya DuPont inayamba kugwiritsa ntchito ethylene ndi Malo a-Low density poly (B) adakonzedwa kuchokera ku olefin ndi njira yothetsera. PE ndiyotsika mtengo, yosinthika, yolumikizidwa komanso yosagwirizana ndi dzimbiri. LDPE imagwiritsidwa ntchito popanga mafilimu ndi zida zoyikamo HDPE imagwiritsidwa ntchito kwambiri popanga zotengera, mapaipi ndi zida zamagalimoto.
Kampani yathu imagwiritsa ntchito zinthu za polyethylene
Zhongshang huangpu guoyu pulasitiki zopangidwa fakitale Bizinesi yaikulu ya magawano ndi makampani pulasitiki, koma posankha zipangizo adzasankha polyethylene, chifukwa ndi Polyethylene wake odorless, sanali poizoni, amamva ngati sera, ali kwambiri otsika kutentha kukana (ntchito osachepera kutentha kumatha kufika -100 ~ -70 ° C), kukhazikika kwamankhwala abwino, kukana kukokomeza kwa asidi ambiri ndi alkali (osagonjetsedwa ndi asidi okhala ndi okosijeni). Insoluble zosungunulira zambiri pa kutentha firiji, mayamwidwe otsika madzi, wabwino kutchinjiriza magetsi .. Ichi ndi chitsimikizo bwino kwa makasitomala amene kugula katundu wathu, Chofunika kwambiri, polyethylene ndi zinthu zachilengedwe wochezeka, ndi kuipitsidwa kwa chilengedwe mu anthu amakono akukhala kwambiri. kwambiri. Japan imanyalanyaza zoletsa zapadziko lonse lapansi pakutayira zinyalala za nyukiliya, zomwe zimawononga chilengedwe. Zomwe tingachite ndikuyesetsa kuteteza chilengedwe chomwe titha kukhalamo
