Izikhwama zokupakisha zepulasitiki zenziwa ngama-granules epulasitiki njengezinto zokwakha eziluhlaza, ngokuya ngezidingo ezahlukahlukene zezinto ezisetshenziswayo ezihlukene zisetshenziselwa ukuhlanganisa ndawonye, ​​ezenziwe ngemikhiqizo ehlukahlukene esikubonayo, enemikhiqizo ehlukene, izici ezihlukile, ezisebenza kwimikhiqizo ehlukene emikhakheni ehlukene.

1, izikhwama zepulasitiki zePollethylene Plastic

I-Polyethylene ye-High-Pressure, eyaziwa nangokuthi i-polyethylene ephansi (i-LDPE), inkambo yombuso osobala, ukuvela kokufakelwa kwemikhiqizo yepulasitiki kungcono kune-polyethylene ephansi. Ukusetshenziswa kwayo okuyinhloko kunezigaba ezi-3:

A, Ukupakishwa kokudla: amakhekhe, ama-Pipi, izimpahla ezithosiwe, amabhisikidi, i-powder yobisi, usawoti, itiye, njll;

B, ukupakishwa kwemikhiqizo ye-fiber: amahembe, okokugqoka, imikhiqizo yekotini yenaliti, imikhiqizo yamakhemikhali fiber;

C, Ukupakishwa kwemikhiqizo yamakhemikhali yansuku zonke.

2, izikhwama zepulasitiki zePolyethylene Plastic

I-Polyethylene ye-Low-Pessure, eyaziwa nangokuthi i-polyethylene ephezulu (HDPE), ngenxa yesilinganiso sayo esiphakeme se-crystallity, ukucaca akukuhle, ngokuvamile umbuso osobala, ukucaciswa kwemikhiqizo ephezulu ye-polyethylene HDPE imikhiqizo eyisikhwama sePolyethylene HDPE. Ukusetshenziswa kwalo okuyinhloko yizigaba ezi-4:

A, izikhwama zemfucumfucu, izikhwama zamakhowe;

B, izikhwama ezilula, izikhwama zokuthenga, izikhwama zezikhwama, izikhwama ze-vest;

C, isikhwama esisha;

D, Weven Bag Inner Bag

3, izikhwama zepulasitiki zePolypropylene

Izikhwama zepulasitiki zePolypropylene ze-polypropylene ehlobene ne-polyethylene, amandla ayo e-crystalline azokwenza buthaka isidingo, ikakhulukazi i-atactic polypropylene, i-crystallity ebuthakathaka, ukuvela kokusobala kwemikhiqizo yayo yepulasitiki kuphakeme kakhulu.

Isetshenziselwa ikakhulukazi ukupakisha izindwangu, imikhiqizo yekotini yenaliti, okokugqoka, amahembe nokunye.

Izikhwama zokuqala zepulasitiki ezintathu ngenxa yesakhiwo sazo sezinto ezibonakalayo zezizathu ezingezona ze-polar, akulula ukudaya noma ukuphrinta, isidingo sokwelashwa kokuphrinta okungaphezulu.

4, polyvinyl chloride izikhwama zepulasitiki

Izikhwama zepulasitiki zePolyvinyl Chloride, yi-polyvinyl chloride resin blow blow inqubo yokubumba, okuphathelene nezikhwama zokuqala zepulasitiki ezintathu, ukwenziwa kwayo okubonakalayo kubuthakathaka, ngasikhathi sinye ngenxa yokwengeza kwe-chlorine, kube lula ukuphrinta ngombala. Ukusetshenziswa kwayo okuyinhloko kwezici ezi-2:

A, izikhwama zezipho;

B, izikhwama, izikhwama zemikhiqizo yenaliti kanye nemikhiqizo yekotini, izikhwama zokuhlobisa;

Izikhwama zepulasitiki ezi-5, ze-biodegramable

Izikhwama zepulasitiki ezingokonakala zemvelo zonke izinhlobo zezikhwama zepulasitiki ze-biodegradable, ngokuthuthukiswa kwesayensi nobuchwepheshe, zonke izinhlobo zezinto zokwakha zingase zithathe indawo yezinto zokwakha amapulasitiki zendabuko, kufaka phakathi ezinye izinto ze-polymer nezinye izinto ze-polymer. Konke kungathatha isikhundla sezikhwama zepulasitiki zendabuko PE. Izikhwama zepulasitiki zemvelo zisetshenziswe kabanzi: Izikhwama zokuthenga ezitolo ezinkulu, ngisho nevolumu yezikhwama ezintsha, i-mulch, njll. Ezweni linezibonelo ezinkulu zohlelo lokusebenza.
