1. Kusimudzirwa kwemitemo.

Nhevedzano yemitemo nemirairo pakuvaka kuchengetedza kwesimba zvakaziviswa muChina.Kuchengetedza simba uye kuderedzwa kwekubuda kwemapurojekiti ekuvaka ndiyo nzira yakakosha yekudyara kwehurumende, uye mutemo wekuchengetedza simba rekuvaka rave simba rakakosha rekufambisa kumusika wepolyurethane.

2. Indasitiri yemotokari.

Huwandu hwemapurasitiki emotokari senge polyurethane zvinhu chiratidzo chakakosha chekuyera hunyanzvi hwekuita zvemazuva ano dhizaini nekugadzira mota.Parizvino, avhareji mashandisirwo emotokari emotokari munyika dzakasimukira angangoita 190kg / mota, achiverengera 13% -15% yehuremu hwemotokari, nepo avhareji kushandiswa kwemotokari munyika yangu kuri 80-100kg / mota, inoverengera. 8% yemotokari inorema, uye chiyero chekushandisa chiri pachena chakaderera.
Muna 2010, kugadzirwa kwemotokari munyika yangu uye kutengesa kwakasvika 18.267 miriyoni uye 18.069 miriyoni zvakateerana, chinzvimbo chekutanga pasirese.Zvinoenderana ne "Gumi neshanu-Gore Chirongwa" cheindasitiri yemotokari, panosvika 2015, iyo chaiyo yekugadzira mota munyika yangu ichasvika 53 mamirioni emotokari.Kuvandudzwa kweramangwana kweindasitiri yemotokari yenyika yangu kuchachinja zvishoma nezvishoma kubva pakutsvaga kugona kwekugadzira uye chiyero kuenda kutarisisa pamhando uye nhanho.Muna 2010, kushandiswa kwePU muindasitiri yemotokari yenyika yangu kwaisvika mazana matatu ezviuru zvematani.Mune ramangwana, nekuwedzera kwakanyanya mukugadzirwa kwemotokari dzenyika yangu uye kuwedzera kwehuwandu hwekushandiswa kwepurasitiki, zvinotarisirwa kuti panosvika 2015, kushandiswa kwePU muindasitiri yemotokari yenyika yangu kuchasvika 800,000-900,000 matani.

3. Kuvaka kuchengetedza simba.

Zvinoenderana nedanho renyika yangu rekuchengetedza simba rekuisa basa, pakupera kwa2010, zvivakwa zvemudhorobha zvinofanirwa kusangana neyakagadzika chiyero che50% chekuchengetedza simba, uye panosvika 2020, simba rose rekushandisa kwezvivakwa munharaunda yese rinofanira kuwana simba rinosvika makumi matanhatu neshanu. kuchengetedza.Parizvino, chinhu chikuru chekuvaka kuchengetedza kwesimba muChina ndeye polystyrene.Kuti uwane chinangwa chekuchengetedza simba che65% muna 2020, zvinofanirwa kuita akakwana ekuchengetedza simba kumadziro ekunze e43 bhiriyoni square metres yezvivakwa.Pakati pezvivakwa zvinochengetedza magetsi ekudzivirira kupisa kwemafuta munyika dzakabudirira, polyurethane inotora 75% yemugove wemusika, nepo isingasviki 10% yezvazvino zvivakwa zvinopisa zvekupisa zvemukati munyika yangu zvinoshandisa polyurethane rigid foam zvinhu.munda wekushandisa.

4. Kudiwa kwemusika kwefirijis nezvimwefirijimidziyo.

Polyurethane ine basa risingadzokerike mukushandiswa kwemafiriji nemafiriza.Nekuvandudzwa kwemaguta, kuwedzera kwekufarirwa kwemafiriji uye kukwidziridzwa kwezvigadzirwa zvakafambisa kuvandudzwa kwemisika yefiriji nefiriji, uye nzvimbo yekusimudzira yepolyurethane mumunda wemafiriji nemafiriza yakawedzerawo.
