Lipolasetiki tse fetotsoeng li bua ka lihlahisoa tsa polasetiki motheong oa li-plastiki tsa maiketsetso tse akaretsang le li-plastiki tsa boenjineri tse sebetsitsoeng le ho fetoloa ka mekhoa e kang ho tlatsa, ho kopanya le ho matlafatsa ho ntlafatsa pherekano ea lelakabe, matla, ho hanyetsa tšusumetso le ho ba thata.
Lipolasetiki tse tloaelehileng hangata li na le litšobotsi le litšitiso tsa tsona. Likarolo tsa polasetiki tse fetotsoeng ha li khone feela ho fihlela tšebetso ea matla a litšepe tse ling, empa hape li na le letsoalo le tlase, ho ba thata haholo, ho hanyetsa ts'enyeho, ho ba le tšusumetso e matla, matla a holimo le ho roala. Letoto la melemo, joalo ka anti-vibration le lelakabe-retardant, le hlahile liindastering tse ngata, mme ho batla ho le thata ho fumana sesebelisoa se ka nkang lihlahisoa tsa polasetiki sebakeng se seholo mothating ona.
Lilemong tsa morao tjena, nts'etsopele e potlakileng ea liindasteri tsa ho etsa le ho etsa lihlahisoa lefats'eng ka bophara e khothalelitse tlhoko ea moreki ea li-plastiki tse fetotsoeng.
Ho 2018, tlhoko ea China bakeng sa polasetiki e fetotsoeng e fihlile lithane tse limilione tse 12.11, keketseho ea selemo le selemo ea 9.46%. Tlhokahalo ea li-plastiki tse fetotsoeng lekaleng la likoloi ke lithane tse limilione tse 4.52, tse ikarabellang bakeng sa 37%. Karolo ea li-plastiki tse fetotsoeng ka har'a thepa ea kahare ea makoloi e eketsehile ho feta 60%. Joaloka thepa ea bohlokoa ka ho fetesisa ea makoloi, e ke ke ea fokotsa boleng ba likarolo feela ka 40%, empa hape e ka fokotsa litšenyehelo tsa theko ka 40%. .
Likopo tse ling tsa polasetiki e fetotsoeng lebaleng la likoloi
Hajoale, thepa ea PP (polypropylene) le PP e fetotsoeng li sebelisoa haholo likarolong tsa kahare tsa makoloi, likarolo tsa kantle le likarolo tse tlase. Linaheng tse tsoetseng pele tsa indasteri ea likoloi, tšebeliso ea thepa ea PP bakeng sa libaesekele e etsa 30% ea lipolasetiki tsa makoloi kaofela, e leng mofuta o sebelisoang ka ho fetesisa oa thepa eohle ea polasetiki likoloing. Ho latela moralo oa nts'etsopele, ka 2020, sepheo se tloaelehileng sa ts'ebeliso ea polasetiki bakeng sa likoloi se tla fihla 500kg / koloi, se ikarabellang ho feta 1/3 ea thepa eohle ea likoloi.
Hajoale, ho ntse ho na le lekhalo lipakeng tsa baetsi ba polasetiki ba China ba fetotsoeng le linaha tse ling. Tataiso ea nts'etsopele ea li-plastiki tse fetotsoeng e na le lintlha tse latelang:
1. Phetoho ea polasetiki e akaretsang;
2. Li-plastiki tse fetotsoeng li sebetsa hantle haholo, li sebetsa ka bongata ebile li na le likarolo tse ngata;
3. Theko e tlase le ho etsa indasteri ea li-plastiki tse khethehileng;
4. Ts'ebeliso ea mahlale a phahameng a joalo ka theknoloji ea nanocomposite;
5. Tala, ts'ireletso ea tikoloho, khabone e tlase le ho nchafatsoa ha li-plastiki tse fetotsoeng;
6. Hlahisa lisebelisoa tse ncha tse nang le bokhoni bo phahameng 'me u fetole lehoakhoa le khethehileng la motheo
Ts'ebeliso e fokolang ea polasetiki e fetotsoeng ka lisebelisoa tsa lapeng
Ntle le tšimo ea makoloi, lisebelisoa tsa lapeng le tsona ke lebala moo ho sebelisoang li-plastiki tse fetotsoeng. China ke mohlahisi e moholo oa lisebelisoa tsa lapeng. Lipolasetiki tse fetotsoeng li 'nile tsa sebelisoa haholo ho li-conditioner tsa moea le lihlahisoa tse ling nakong e fetileng. Ho 2018, tlhoko ea li-plastiki tse fetotsoeng lebaleng la lisebelisoa tsa lapeng e ne e le lithane tse ka bang limilione tse 4.79, tse ikarabellang bakeng sa 40%. Ka nts'etsopele ea lihlahisoa tse phahameng, tlhoko ea li-plastiki tse fetotsoeng lebaleng la lisebelisoa tsa lapeng e eketsehile hanyane ka hanyane.
Eseng hoo feela, hobane li-plastiki tse fetotsoeng hangata li na le motlakase o motle, li bapala karolo ea bohlokoa makaleng a motlakase le a elektroniki.
Matla a motlakase, ho hanela ha metsi ka holimo, le ho hanela bophahamo ba modumo hangata ho ka fihlela litlhoko tsa lihlahisoa tsa motlakase tse nang le matla a tlase haholo. Hajoale, lisebelisoa tsa motlakase tse nang le matla a tlase li ntse li tsoela pele ntlheng ea miniaturization, multi-function, le high current, e hlokang ts'ebeliso ea lisebelisoa tsa polasetiki ka matla a betere le khanyetso e phahameng ea mocheso.
Likhamphani tse ngata tsa China li ntse li hlahisa li-plastiki tse khethehileng tse fetotsoeng joalo ka PA46, PPS, PEEK, jj, molemong oa ho fana ka lisebelisoa tsa polasetiki tse sebetsang hantle bakeng sa baetsi ba lisebelisoa tsa motlakase tse nang le matla a tlase. Tlas'a tloaelo ea 5G ho 2019, likarolo tsa antenna li hloka lisebelisoa tsa kamehla tsa dielectric, 'me lisebelisoa tsa kamehla tsa dielectric tse tlase li hlokahala ho fihlela latency e tlase. Sena se na le litlhoko tse phahameng bakeng sa polasetiki e fetotsoeng hape se tlisa menyetla e mecha.
