Izinto ezisetshenziswa elabhorethri angamathuluzi asetshenziswa ngesikhathi sokuhlolwa. Kunezinhlobo eziningi zazo. Ngokwezinto ezisetshenziswayo, zihlukaniswe izigaba ezintathu: ingilazi, ipulasitiki nensimbi. Phakathi kwazo, ipulasitiki izuze izinzuzo eziningi ngenxa yokusebenza kwayo okuhle kakhulu nokubunjwa okulula. Ziyanda ukusetshenziswa kabanzi. Izinto ezijwayelekile zifaka lezi zigaba ezilandelayo:
PP (i-polypropylene): i-translucent, ikhemikhali kanye nokuzinza kwezinga lokushisa kungcono, ukuzwa kwesandla kunamandla kune-PE, futhi kungasetshenziswa cishe amadigri angu-100, kodwa iba brittle lapho izinga lokushisa eliphansi liphansi, alikwazi ukumelana nemihuzuko, ukuguga kalula, ukumelana nokugqwala, i-asidi evamile, izinyibilikisi ze-alkaline azinawo umthelela omncane kuwo.
I-PE (i-polyethylene): i-opaque, ukuqina okuqinile, anti-ukuguga, isisindo esilula, ukungavuzi, ukuthungwa okuthambile, futhi ayisebenzi nge-acetone, i-acetic acid, i-hydrochloric acid, njll., izinzile, futhi kulula ukuthambisa kumazinga okushisa aphezulu.
PS (polystyrene): transparent , ukuqina okuphezulu, nezinga lokushisa lengilazi elishintshayo elingaphezu kuka-100 ℃, elizinzile ezixazululweni eziningi ezinamanzi, kodwa lizogqwala ngenxa yezinto ezihlukahlukene eziphilayo.
I-PC (i-polycarbonate): Inamandla amakhulu futhi ukuqina, amandla omthelela aphezulu, ukubonakala okuhle, ubulukhuni obuphezulu, futhi kungaba yinyumba i-zed emazingeni okushisa aphezulu, kodwa ayimelani nama-acids aqinile nama-alkali nezinye izincibilikisi eziphilayo ezifana notshwala.
PETG (i-polyethylene terephthalate): imikhiqizo yayo isobala kakhulu, iqinile kahle, ifanele ukwakha imikhiqizo ebonisa ngale enezindonga eziwugqinsi, i-PETG inokuhle kakhulu ukucubungula nokwenza ukusebenza, futhi kungaklanywa kunoma yisiphi isimo ngokuya ngomklami' izinjongo zakhe. I-Traditional Extrusion, ukubumba umjovo, ukubumba igalelo kanye nezindlela zokubumba amabhamuza.
Okungenhla kuyizinto ezisetshenziswayo zaselabhorethri ezivamile. Ngokuthuthuka kokuqwashisa kwabantu ngokuzivikela, izinto ezisetshenziswa ingilazi ezintekenteke kancane kancane zithathelwa indawo yizinto zepulasitiki futhi zibe izinto ezijwayelekile zokusetshenziswa.
The FAI climbed 5.9 percent year-on-year in the first 11 months of 2018, quickening from the 5.7-percent growth in Jan-Oct, the National Bureau of Statistics (NBS) said Friday in an online statement.
The key indicator of investment, dubbed a major growth driver, hit the bottom in August and has since started to rebound steadily.
In the face of emerging economic challenges home and abroad, China has stepped up efforts to stabilize investment, in particular rolling out measures to motivate private investors and channel funds into infrastructure.
Friday's data showed private investment, accounting for more than 60 percent of the total FAI, expanded by a brisk 8.7 percent.
NBS spokesperson Mao Shengyong said funds into weak economic links registered rapid increases as investment in environmental protection and agriculture jumped 42 percent and 12.5 percent respectively, much faster than the average.
In breakdown, investment in high-tech and equipment manufacturing remained vigorous with 16.1-percent and 11.6-percent increases respectively in the first 11 months. Infrastructure investment gained 3.7 percent, staying flat. Investment in property development rose 9.7 percent, also unchanged.
