Yintoni i-LDPE Plastiki kwaye isetyenziswa njani?

Iiplastiki zikho kuyo yonke indawo ebomini bethu. I-LDPE, okanye i-Low-Density Polyethylene, yiplastiki eguquguqukayo neyimfuneko esetyenziswa kumashishini amaninzi.

Kule posi, uya kufunda ukuba yintoni iplastiki ye-LDPE kunye nokuba isetyenziswa njani kwizicelo ezahlukeneyo.

Yintoni i-LDPE?

I-Low-Density Polyethylene (LDPE) yipolymer ye-thermoplastic ephuma kwi-ethylene. Yaziwa ngokudityaniswa okukodwa kokuguquguquka, ukungafihli, kunye nenqanaba elisezantsi lokunyibilika.

Ukwakheka kweekhemikhali ze-LDPE yi-(C2H4)n, apho i-n imele inani leeyunithi ze-monomer. Amakhonkco e-polymer anesakhiwo se-branched, esinika i-LDPE iimpawu zayo ezahlukileyo.

Ezinye iimpawu eziphambili ze-LDPE ziquka:

• Ukuguquguquka: Inokolulwa ngokulula kwaye ibunjwe

• Ukungafihli: Ivumela ukukhanya ukuba kudlule, iyenze ilungele ukupakishwa okucacileyo

• Iqondo eliphantsi lokunyibilika: Inokucutshungulwa kumaqondo obushushu aphantsi xa kuthelekiswa nezinye iintlobo zepolyethylene

I-LDPE vs. Ezinye Iindidi zePolyethylene:

Ipropati ye	-LDPE	HDPE	LLDPE
Ubuninzi (g/cm3)	0.915-0.935	0.941-0.965	0.915-0.925
Amandla Okuqina (MPa)	8-31	18-35	15-29
Indawo yokunyibilika (°C)	105-115	120-140	120-130
Ukungafihli	Phezulu	Phantsi	Phezulu

Njengoko kubonwe kwitheyibhile, i-LDPE inoxinano olusezantsi kunye nendawo yokunyibilika xa kuthelekiswa ne-HDPE. Ikwabonelela ngokucace ngakumbi kune-HDPE. I-LLDPE yabelana ngezinto ezifanayo kunye ne-LDPE kodwa inolwakhiwo lomda ngakumbi.

Yenziwa njani i-LDPE?

Ukuveliswa kwe-LDPE kuqala nge-ethylene, imathiriyeli ekrwada evela kwi-petroleum. Le monoma ingena kwipolymerization yoxinzelelo oluphezulu ukwenza ipolymer esiyazi njenge-LDPE.

Inkqubo yokuvelisa ibandakanya iindlela ezimbini eziphambili:

1. Indlela ye-Autoclave Reactor
