Tinkomishi tepulasitiki angeke tenteke ngaphandle kwemapulasitiki. Sidzinga kuvisisa emapulasitiki ekucaleni .
Ipulasitiki yentiwa njani?
Indlela lepulasitiki leyentiwa ngayo incike kakhulu ekutsi nguluphi luhlobo lwepulasitiki lolukhona lolusetjentiselwa tinkomishi tepulasitiki. Ngako-ke asicale ngekuhamba ngetinhlobo letintsatfu letehlukene tepulasitiki letisetjentiselwa kwenta tinkomishi tepulasitiki. Letinhlobo letintsatfu letehlukene tepulasitiki yi-PET, rPET kanye nepulasitiki ye-PLA.
A. Ipulasitiki ye-PET
I-PET imelela i-polyethylene terephthalate, lokuyinhlobo levame kakhulu yepulasitiki. I-PET yi-thermoplastic polymer resin levame kakhulu yemndeni we-polyester futsi isetjentiswa emicu yetimphahla, titja tetintfo letimanti nekudla, kanye ne-thermoforming yekukhicita, futsi ngekuhlanganiswa ne-fibre yengilazi ye-resin yebunjiniyela. kuphindze kusetjentiswe futsi kusetjentiselwe letinye rPET. Iphindze ibe yintfo lesetjentiswa kakhulu ekwenteni tinkomishi tepulasitiki ngoba kunekuphakelwa lokukhulu kwayo, futsi ivunyelwe kutsi ihlangane netintfo tekudla.
Lepulasitiki yentiwa nge oyili ye Naphtha lekuyincenye ye oyili leluhlata, loku kwentiwa ngesikhatsi sekucolisa lapho khona lamafutsa ahlukana abe yi Naphtha, iHydrogen kanye naletinye tincenye. Le oyili lekhishwako iNaphtha ibese iba yipulasitiki ngendlela lebitwa ngekutsi yi Polymerization. Lenchubo ihlanganisa i-ethylene ne-propylene kwenta emaketanga e-polymer ekugcineni nguloko lokukhicitwa yipulasitiki ye-PET.
B. ipulasitiki ye-rPET
rPET imelela i-polyethylene terephthalate lephindze isetjentiswe, futsi luhlobo loluvame kusetjentiswa kakhulu lwepulasitiki lephindze isetjentiswe, ngoba kucina kwe PET kwenta kubelula kuyiphindze isetjentiswe futsi kusacinisekisa lizinga leliphakeme. I-PET lephindze isetjentiswe iba luhlobo lolusetjentiswa kakhulu lwepulasitiki jikelele, futsi tinkampani letinyenti tizama kwenta imikhicito yato kusuka ku-rPET esikhundleni se-PET levamile. Loku ikakhulukati imboni yekwakha, lapho khona emafasitelo lamanyenti akhiwa ngepulasitiki ye-rPET. Empeleni kungaba futsi luhlaka lwetibuko.
C. Ipulasitiki ye-PLA
Ipulasitiki ye PLA yi polyester lekhicitwa tintfo letisekelwe etitjalweni letifana nesitashi sembila noma umoba. Uma usebentisa loku kukhicita PLA ipulasitiki lapho umbhangqwana tinyatselo. Tintfo letisetjentiswako tihamba ngekugaya lokumanti, lapho khona sitashi sihlukaniswa naletinye tintfo letikhishwa kuletintfo tesitjalo. Lesitashi sibese sihlanganiswa ne esidi noma ema enzymes bese ekugcineni siyashiswa. Lesitashi sembila sitawuba yi D-glucose, bese siyahamba ngendlela yekuvubela letawusigucula sibe yi Lactic Acid.
I-PLA seyibe yintfo lethandwako ngenca yekutsi ikhicitwa ngekwemnotfo kusuka etintfweni letivuselelwako. Kusetjentiswa kwayo lokusakateke kakhulu kuvinjelwe kushoda lokunyenti kwemtimba kanye nekucubungula.
Tinkomishi tepulasitiki takhiwe njani?
Uma kukhulunywa ngetinkomishi tepulasitiki nekutsi tinkomishi tepulasitiki takhiwe njani empeleni kwenta umehluko uma ngabe tinkomishi tepulasitiki letilahlwako noma letiphindze tisetjentiswe. Tinkomishi tepulasitiki takhiwe nge polyethylene terephthalate, noma iPET, ipulasitiki lecinile kakhulu lemelana nekushisa lokushisako nalokubandzako futsi iyamelana nekudzabuka. Ngendlela leyatiwa ngekutsi kubumba ngekujova, le PET ihlanganiswa njengeliketjezi, ijovwe etikhunjini letimise njengenkomishi bese iyapholiswa futsi icinise.
Letinkomishi tepulasitiki takhiwa ngendlela lebitwa ngekutsi kubumba ngekujova, lapho khona tintfo tepulasitiki tihlanganiswa netintfo letimanti bese tifakwa esifanekisweni setinkomishi tepulasitiki, lokuncuma bukhulu kanye nebukhulu baletinkomishi.
Ngako-ke yini intluences it tinkomishi tepulasitiki kwentiwa njengekulahlwa noma kuphindze kusetjentiswe kuya onthe tifanekiso the
bakhiciti bemishini yekushisa yepulasitiki kusebentisa.
Hlakaniphile Umshini Wekushisa Inkomishi Yepulasitiki Ikakhulukati kukhicita titja tepulasitiki letehlukahlukene ( tinkomishi te jelly, tinkomishi tekunatsa, titja temaphakheji, njll) ngemashidi epulasitiki leshisako, njenge PP, PET, PE, PS, HIPS, PLA, njll.
Iumshini wekwenta tinkomishi tepulasitiki ilawulwa yi-hydraulic kanye ne-servo, ngekudla kweshidi le-inverter, luhlelo lolucondziswa yi-hydraulic, kwelula kwe-servo, loku kwenta kutsi kube nekusebenta lokuzinzile kanye nemkhicito wekucedza ngelizinga leliphakeme. Ikakhulukati kukhicita titja tepulasitiki letehlukahlukene letinekujula lokwakhiwe ≤180mm ( tinkomishi te jelly, tinkomishi tekunatsa, titja temaphakheji, njll) letinemashidi epulasitiki leshisako, njenge PP, PET, PE, PS, HIPS, PLA,njll.
