Kodi pulasitiki ndi chiyani?

Pulasitiki amagwiritsidwa ntchito kwambiri ndipo ndizofunikira kwambiri pazida zam'nyumba, magalimoto, mafoni am'manja, ma PC, zida zamankhwala, ndi zida zamagetsi.Ndi kukula kosasunthika komanso kokhazikika kwachuma cha dziko langa, mafakitale monga zida zapakhomo, magalimoto, mafoni a m'manja, ma PC, ndi zida zamankhwala apezanso chitukuko chofulumira kupindula ndi malo abwino akunja.Kukula kwa mafakitale akumunsi kwalimbikitsanso kufunika kwa mapulasitiki.Mu 2010, panali mabizinesi 2,286 mu China pulasitiki mbali makampani kupanga, chaka ndi chaka kuwonjezeka 24.54%;ndalama zogulitsa zafika 106.125 biliyoni ya yuan, kuwonjezeka kwa chaka ndi 26.38%.

Munthawi ya 12th Year Plan Plan, mafakitale akunsi kwa dziko langa monga magalimoto, zida zapanyumba, zamagetsi ogula, ndi zida zamankhwala zipitilizabe kupititsa patsogolo chitukuko mwachangu.Kufunika kwa magawo apulasitiki m'mafakitalewa kudzapitilira kukula, ndipo kufunikira kudzawonetsanso mayendedwe apamwamba komanso olondola.Akuti mu nthawi ya 12 ya zaka zisanu, kuchuluka kwa malonda amakampani opanga zigawo zapulasitiki ku China kudzafika 170 biliyoni.Malinga ndi kafukufuku CIC, luso luso luso la China pulasitiki mbali makampani kupanga wakhala zina patsogolo, ndi chiwerengero cha ogwira ntchito luso R & D malo anapitiriza kuwonjezeka;kapangidwe ka mafakitale, kapangidwe ka bizinesi ndi kapangidwe kazinthu zakhala zikusinthidwa mosalekeza, ndipo kukula kwa mafakitale kwasinthidwa pang'onopang'ono;ubwino wonse wa makampani akhala patsogolo patsogolo ndi Kulimbitsa, kusiyana ndi mayiko otukuka padziko lapansi pang'onopang'ono ndi pang'onopang'ono, ndipo mbali zina zafika pa mlingo wapadziko lonse lapansi, kulowa mu nthawi yovuta ya chitukuko zisathe kuchokera dziko lalikulu kupita patsogolo. ndi dziko lamphamvu.Makampani opanga magawo apulasitiki ku Jiangsu, Zhejiang, Shanghai, Guangdong ndi malo ena akuchulukirachulukira.Onse kuchuluka kwa mabizinesi ndi kukula kwa kupanga ndi kugulitsa ndizotsogola m'dzikolo, ndipo ndende yamakampaniyi ndiyokwera kwambiri.

Ndi pulasitiki monga zopangira zazikulu, zinthu zosiyanasiyana za pulasitiki kapena zigawo zake zimapangidwa ndi umisiri wokonza monga jekeseni, extrusion, ndi kuumba zopanda pake.
Zopangidwa ndi pulasitiki zimapangidwa ndi pulasitiki ndi polymerized ndi polyaddition kapena polycondensation, yomwe imadziwika kuti pulasitiki kapena utomoni.The zikuchokera ndi mawonekedwe akhoza momasuka kusinthidwa.Amapangidwa ndi ma resins opangira ndi zowonjezera monga zodzaza, mapulasitiki, zolimbitsa thupi, zothira mafuta, ndi ma pigment.
Mphira umagawidwa kukhala mphira wachilengedwe komanso mphira wopangira.
Labala wachilengedwe amachokera ku mtengo wa Hevea sinensis.Pamene epidermis ya mtengo wa rabara yadulidwa, madzi oyera amkaka amatuluka, otchedwa latex.The latex ndi coagulated, kutsukidwa, mawonekedwe ndi zouma kuti apeze mphira zachilengedwe.
Labala yopangira imapangidwa ndi kaphatikizidwe, ndipo mitundu yosiyanasiyana ya mphira imatha kupangidwa pogwiritsa ntchito zida zosiyanasiyana (monomers).
khalidwe
1) Kukana mankhwala
2) Zambiri ndi zonyezimira.
3) Ambiri aiwo ndi ma insulators abwino
4) Wopepuka komanso wamphamvu
5) Ndiosavuta kukonza ndipo imatha kupangidwa mochuluka, ndipo mtengo wake ndi wotsika mtengo
6) Zogwiritsa ntchito zosiyanasiyana, ntchito zambiri, zosavuta kuziyika, komanso kukana kutentha kwambiri
