Ubwoko busanzwe no kumenyekanisha plastike.

Plastike, ni ukuvuga reberi ya pulasitike, ni reberi ya rubber yakozwe na polymerisation y'ibicuruzwa bitunganya peteroli hamwe nibintu bimwe na bimwe bya shimi.Itunganywa nababikora kugirango bakore ibicuruzwa bya plastike muburyo butandukanye.

1. Gutondekanya plastike: Nyuma yo gutunganya no gushyushya, plastiki irashobora kugabanywamo ibyiciro bibiri: thermoplastique na thermosetting.Ibisanzwe ni ibi bikurikira:
1) PVC - chloride ya polyvinyl
2) PE - polyethylene, HDPE - polyethylene yuzuye, LDPE - polyethylene yuzuye
3) PP - Polypropilene
4) PS - polystirene
5) Ibindi bikoresho bisanzwe byo gucapa ni PC, PT, PET, EVA, PU, ​​KOP, Tedolon, nibindi.

2. Uburyo bworoshye bwo kumenyekanisha ubwoko butandukanye bwa plastiki:
Tandukanya ukurikije isura:
1) kaseti ya PVC iroroshye kandi ifite ubwaguke bwiza cyane.Mubyongeyeho, hari nibikoresho bimwe bikomeye cyangwa byinshi, nk'imiyoboro y'amazi, inzugi zinyerera, nibindi.
2) PS, ABS, yoroshye kandi yoroheje, muburyo bwo gutera inshinge.
3) HDPE muri PE ni yoroheje muburyo bwiza, nziza mubukomere na opaque, mugihe LDPE ihindagurika gato.
4) PP ifite umucyo runaka kandi iracitse.

Tandukanya ukurikije imiterere yimiti:
1) PS, PC na ABS zirashobora gushonga muri toluene kugirango zangirike hejuru yazo.
2) PVC ntishobora gukemurwa na benzene, ariko irashobora gushonga hamwe na ketone solvent.
3) PP na PE bifite anti-alkali nziza kandi irwanya solvent nziza.

Tandukanya ukurikije umuriro:
1) Iyo PVC yatwitse n'umuriro, izabora umunuko wa chlorine, kandi umuriro umaze kugenda, ntuzashya.
2) PE izabyara impumuro nziza mugihe yaka, hamwe nibitonyanga, ariko PP ntabwo, kandi byombi bizakomeza gutwika nyuma yo kuva mumuriro.

3. Ibiranga plastiki zitandukanye
1) Ibiranga PP: Nubwo PP ifite umucyo, imiterere yayo iroroshye kumeneka, nibyiza kubipakira ibiryo.Ibicuruzwa bitandukanye birashobora kuvamo mugutezimbere inenge zavunitse.Kurugero: OPP na PP byongerewe muburyo butandukanye kugirango bongere imbaraga zabo, zikunze gukoreshwa mugupakira hanze yimyenda yimpapuro na chopsticks.
2) Ibiranga PE: PE ikozwe muri Ethylene.Ubucucike bwa LDPE ni 0,910 g / cm-0,940 g / cm.Kubera ubukana buhebuje n'ubushobozi bwo kwirinda ubushuhe, ikoreshwa kenshi mubipfunyika ibiryo, gupakira kwisiga, nibindi;Ubucucike bwa HDPE ni 0,941 g / cm cyangwa irenga.Kubera ubwinshi bwurumuri hamwe nubushyuhe, ikoreshwa kenshi mumifuka hamwe namashashi atandukanye.
