Mapulasitiki osinthidwa amatanthauza zinthu zapulasitiki pamaziko a mapulasitiki omwe amapangidwa ndi pulasitiki ndi zomangamanga zomwe zasinthidwa ndikusinthidwa ndi njira monga kudzaza, kuphatikiza, ndi kulimbikitsa kukonza kuchepa kwa lawi, mphamvu, kulimbikira, komanso kulimba.
Mapulasitiki wamba nthawi zambiri amakhala ndi mawonekedwe awo ndi zopindika zawo. Zida zosinthidwa za pulasitiki sizingokwaniritsa magwiridwe antchito amtundu winawake, komanso zimakhala ndi kachulukidwe kotsika, kulimba kwambiri, kukana dzimbiri, kukana kwamphamvu, mphamvu yayikulu, ndi kuvala kukana. Zabwino zingapo, monga anti-vibration ndi la-retardant, zatuluka m'mafakitale ambiri, ndipo ndizosatheka kupeza zinthu zomwe zingalowe m'malo mwa zinthu zapulasitiki pamlingo waukulu pano.
M'zaka zaposachedwa, kupita patsogolo mwachangu kwa mafakitale opanga ndikupanga padziko lonse lapansi kwalimbikitsa kwambiri kufunikira kwa ogula ma plastiki osinthidwa.
Mu 2018, kufunika kwa China kwa mapulasitiki osinthidwa kudafika matani 12.11 miliyoni, kuwonjezeka kwa chaka ndi chaka kwa 9.46%. Kufunika kwa mapulasitiki osinthidwa mgalimoto ndi matani 4.52 miliyoni, omwe amawerengera 37%. Gawo la mapulasitiki osinthidwa muzinthu zamkati zamagalimoto lawonjezeka kupitilira 60%. Monga zida zofunikira kwambiri zamagalimoto, sizingangotsitsa magawo 40%, komanso kuchepetsa mtengo wogula pafupifupi 40%. .
Ntchito zina zamapulasitiki osinthidwa pamunda wamagalimoto
Pakadali pano, zida za PP (polypropylene) ndi ma PP osinthidwa amagwiritsidwa ntchito kwambiri pagalimoto mkati, mbali zakunja ndi magawo osasungika. M'mayiko otukuka agalimoto, kugwiritsa ntchito zida za PP zama njinga kumawerengera 30% yamapulasitiki onse agalimoto, omwe ndi mitundu yazipangizo zonse zapulasitiki. Malinga ndi pulani yachitukuko, pofika chaka cha 2020, kuchuluka kwamagalimoto omwe amagwiritsidwa ntchito pamagalimoto adzafika ku 500kg / galimoto, kuwerengera zoposa 1/3 yazinthu zonse zamagalimoto.
Pakadali pano, pali kusiyana pakati pa opanga opanga mapulasitiki aku China ndi mayiko ena. Njira yakutsogolo yopangira mapulasitiki osinthidwa ili ndi izi:
1. Kusinthidwa kwa mapulasitiki wamba;
2. Mapulasitiki osinthidwa ndi magwiridwe antchito, magwiridwe antchito komanso kuphatikiza;
3. Kutsika mtengo komanso kutukuka kwamapulasitiki apadera;
4. Kugwiritsa ntchito ukadaulo wapamwamba monga nanocomposite technology;
5. Green, kuteteza zachilengedwe, mpweya wochepa komanso kubwezeretsanso mapulasitiki osinthidwa;
6. Pangani zowonjezera zowonjezera zatsopano ndikusintha utomoni wapadera
Kugwiritsa ntchito pang'ono mapulasitiki osinthidwa pazinthu zapanyumba
Kuphatikiza pa gawo lamagalimoto, zida zapanyumba ndi malo omwe pulasitiki yosinthidwa imagwiritsidwa ntchito. China ndi yomwe imapanga kwambiri zida zapanyumba. Mapulasitiki osinthidwa akhala akugwiritsidwa ntchito kwambiri m'malo opangira mpweya ndi zinthu zina m'mbuyomu. Mu 2018, kufunika kwa mapulasitiki osinthidwa pazida zamagetsi kunali pafupifupi matani miliyoni 4.79, owerengera 40%. Ndikukula kwa zinthu zakumapeto, kufunika kwa mapulasitiki osinthidwa pazida zamagetsi kwachuluka pang'onopang'ono.
Osati zokhazo, chifukwa mapulasitiki osinthidwa nthawi zambiri amakhala ndi kutchinjiriza kwamagetsi, amatenga gawo lofunikira pamagetsi amagetsi ndi zamagetsi.
Mphamvu zamagetsi, zotchinga pamwamba, komanso mphamvu zamagetsi zimatha kukwaniritsa zofunikira zamagetsi zamagetsi zotsika kwambiri. Pakadali pano, zida zamagetsi zamagetsi zotsika pang'ono zikukula motsatira njira ya miniaturization, ntchito zambiri, komanso zamakono, zomwe zimafunikira kugwiritsa ntchito zida zapulasitiki molimba komanso kutentha kwambiri.
Makampani ambiri aku China akupanganso mapulasitiki osinthidwa monga PA46, PPS, PEEK, ndi zina zambiri, kuti athe kupereka bwino zida za pulasitiki kwa opanga zida zamagetsi zamagetsi otsika. Pansi pa mawonekedwe a 5G mu 2019, zida zama antenna zimafunikira zida zopangira ma dielectric mosalekeza, ndipo zida zosinthira ma dielectric nthawi zonse zimafunikira kuti muchepetse kachedwedwe. Izi ndizofunikira kwambiri pamapulasitiki osinthidwa komanso zimabweretsa mwayi watsopano.
