Chii chinonzi plastiki chigadzirwa?

Plastics anoshandiswa zvakanyanya uye zvinhu zvakakosha mumidziyo yemumba, mota, nharembozha, maPC, midziyo yekurapa, uye mwenje midziyo.Nekukura kwakasimba uye kwakadzikama kwehupfumi hwenyika yangu, maindasitiri akadai semidziyo yemumba, mota, nharembozha, maPC, uye midziyo yekurapa zvakawanawo budiriro yekukurumidza ichibatsirwa nenharaunda yakanaka yekunze.Kuvandudzwa kwemaindasitiri epasi kwakawedzera kudiwa kwemapurasitiki.Muna 2010, paiva 2,286 mabhizinesi muChina epurasitiki zvikamu kugadzira indasitiri, gore-pa-gore kuwedzera 24.54%;mari yekutengesa yakasvika 106.125 bhiriyoni yuan, gore-pa-gore kuwedzera kwe26.38%.

Munguva yechigumi nembiri yeChirongwa cheMakore mashanu, maindasitiri ari pasi penyika yangu akaita semotokari, midziyo yemumba, zvemagetsi zvevatengi, uye midziyo yekurapa icharamba ichichengetedza budiriro nekukurumidza.Kudiwa kwezvikamu zvepurasitiki mumaindasitiri aya kucharamba kuchiwedzera, uye kudiwa kucharatidzawo maitiro epamusoro-soro uye nemazvo.Zvinofungidzirwa kuti mukati menguva yechigumi nembiri yeChirongwa cheMakore mashanu, chiyero chekutengesa cheindasitiri yekugadzira zvikamu zvepurasitiki zvekuChina chichasvika mabhiriyoni zana nemakumi manomwe emayuan.Sekureva kweCIC ongororo, kugona kwehunyanzvi hwekuvandudza tekinoroji yeChina mapurasitiki ekugadzira zvikamu indasitiri yakawedzeredzwa, uye huwandu hwemabhizinesi tekinoroji R&D nzvimbo dzakaramba dzichiwedzera;chimiro cheindasitiri, chimiro chebhizinesi uye chimiro chechigadzirwa zvakagara zvichigadziriswa, uye kusimba kwemaindasitiri kwakakwidziridzwa zvishoma nezvishoma;zvakanakira indasitiri zvakawedzera kuvandudzwa uye Kusimbisa, gaka nenyika dzakasimukira pasirese riri kudzikira zvishoma nezvishoma, uye zvimwe zvinhu zvasvika padanho repamusoro repasi, zvichipinda panguva yakaoma yebudiriro inoenderera kubva munyika huru kuenda kumberi. uye nyika ine simba.Indasitiri yekugadzira zvikamu zvepurasitiki muJiangsu, Zhejiang, Shanghai, Guangdong nedzimwe nzvimbo dziri kuwedzera.Ose ari maviri huwandu hwemabhizinesi uye chiyero chekugadzirwa uye kutengesa zviri munzvimbo inotungamira munyika, uye dunhu reindastiri rakawedzera.

Nepurasitiki seyakanyanya mbishi zvinhu, zvakasiyana zvigadzirwa zvepurasitiki kana zvikamu zvinogadzirwa nekugadzirisa matekinoroji senge jekiseni, extrusion, uye gollow molding.
Zvigadzirwa zvepurasitiki zvinogadzirwa nepurasitiki uye polymerized ne polyaddition kana polycondensation, inowanzozivikanwa sepurasitiki kana resin.Kuumbwa uye chimiro zvinogona kuchinjwa zvakasununguka.Iyo inoumbwa nemasynthetic resins uye additives senge mafirita, plasticizers, stabilizers, lubricant, uye pigment.
Rubha rakakamurwa kuita rabha rechisikigo uye rekugadzira rabha.
Natural rubber inonyanya kutorwa kubva kuHevea sinensis muti.Kana iyo epidermis yemuti werabha inochekwa, muto muchena wemukaka unoyerera, unonzi latex.Iyo latex inobatanidzwa, yakashambidzwa, yakaumbwa uye yakaomeswa kuti iwane rabha chaiyo.
Synthetic rabha inogadzirwa neyakagadzirwa synthesis, uye marudzi akasiyana erabha anogona kugadzirwa nekushandisa akasiyana mbishi zvinhu (monomers).
hunhu
1) Kupikisa kwemakemikari
2) Yakawanda inopenya.
3) Mazhinji acho akanaka insulators
4) Chiedza uye chakasimba
5) Zviri nyore kugadzirisa uye zvinogona kugadzirwa-zhinji, uye mutengo wakachipa
6) Yakasiyana-siyana yekushandiswa, mabasa mazhinji, nyore kuisa ruvara, uye kumwe kupisa kwakanyanya
