Umuzenguruko wa pulasitike uzengurutswe, uzwi kandi nka "guswera umutwe", ni ubwoko bwibikoresho byo mu bwiherero.Igizwe ahanini nibikoresho bya pulasitiki, kandi umurimo wacyo nyamukuru ni ugufata umutwe wogero mu bwiherero.
Igishushanyo mbonera cya pisine ya pisine ya pisine isanzwe ifite ibintu byoroshye, ariko kandi ni ngirakamaro cyane.Nubwoko bwa buri munsi bukenerwa, bushobora gukoreshwa mugushiraho umutwe woguswera no kugumya kumwanya mwiza mugihe cyo kwiyuhagira.Umuzingi wa pulasitike uzengurutswe ni muto cyane, ariko ufite uruhare runini mubwiherero.
Mubyongeyeho, bamwe bafite imitwe ya pulasitike yo kumutwe bafite imitako nayo irimbishijwe no kuvura chrome hejuru, ishobora kongera imbaraga zayo nubwiza.Chrome ni ibikoresho bisanzwe byo gushushanya mubikoresho byuma, kandi indorerwamo zayo zimeze nk'urumuri zishobora gutuma ibikoresho byo mu bwiherero birushaho kuba byiza.Ubuvuzi bwa Chrome burashobora kandi kongera ubwiza no kwambara birwanya imitwe ya plastike yogesha umutwe, kugirango ubuzima bwa serivisi bube bwiza.
Dutanga ibikoresho byose bya screw hamwe namabwiriza yo kwishyiriraho asabwa kugirango ushyire muri paki.
