Icyitonderwa: Itandukaniro mugushiraho ibikoresho bya firime nimpande imbere ninyuma

Nkibikoresho bikoreshwa cyane mubipfunyika, itandukaniro ryibikoresho ninyuma ninyuma ya firime ya kashe ifite akamaro kanini muguhuza ingaruka zo gupakira no kuzamura ubwiza bwibicuruzwa. Iyi ngingo izerekana muburyo burambuye ibikoresho byo gufunga firime no gutandukanya impande zinyuma ninyuma.

1. Ubwoko nibiranga ibimenyetso bya firime

Hariho ubwoko bwinshi bwibikoresho bya firime, harimo PE, PET, PP, PVC, PS na aluminium foil. Ibi bikoresho bifite umwihariko wabyo kandi birakwiriye kubikenerwa bitandukanye.

1. PE (polyethylene) ifunga kashe: ifite ubworoherane no gukorera mu mucyo, igiciro gito ugereranije, ikoreshwa cyane mugupakira ibiryo, ubuvuzi nizindi nganda.

2. PET (polyester) ifunga kashe: ifite imbaraga nyinshi kandi irwanya kwambara, ikwiranye nigihe cyo gupakira bisaba imbaraga nigihe kirekire.

3. PP (polypropilene) ifunga kashe: ifite ubushyuhe buhebuje kandi irwanya ubushuhe, ibereye gupakira ahantu hafite ubushyuhe bwinshi.

4. PVC (polyvinyl chloride) ifunga kashe: ifite ibihe byiza byo guhangana nikirere hamwe n’imiterere y’imiti, ibereye gupakira bisaba kubika igihe kirekire cyangwa ibidukikije bidasanzwe.

5. Filime ya PS (polystirene) ifunga kashe: ifite ububengerane nuburanga bwiza, ibereye ibicuruzwa byo murwego rwohejuru cyangwa gupakira impano.

6. Firime ya aluminiyumu ifunga kashe: ifite inzitizi nziza ninziza nziza, ibereye gupakira isaba inzitizi ndende cyangwa ubwiza bwihariye.

2. Itandukaniro riri imbere ninyuma ya firime ya kashe

Imbere n'inyuma ya firime ya kashe iratandukanye mubintu, isura n'imikorere. Gutandukanya neza no kubikoresha mu buryo bushyize mu gaciro ni ngombwa mu kunoza ingaruka zo gupakira.

1. Itandukaniro ryibigaragara: Imbere ninyuma ya firime ya kashe mubisanzwe bifite itandukaniro rigaragara mumiterere. Uruhande rwimbere rusanzwe rufite uburabyo, rufite ubuso bunoze kandi bworoshye, mugihe uruhande rwinyuma rusa nkaho rwijimye, kandi ubuso bushobora kwerekana imiterere runaka cyangwa ububi. Itandukaniro mumiterere rifasha abakoresha gutandukanya byihuse imbere ninyuma mugihe uyikoresha.

2. Itandukaniro ryimikorere: Imbere ninyuma ya firime ya kashe nayo ifite imikorere itandukanye. Uruhande rwimbere rusanzwe rufite imikorere myiza yo gucapa no kwambara, kandi birakwiriye gucapa ibirango, ibishushanyo, nibindi, kugirango bitezimbere ubwiza no kumenyekanisha ibipfunyika. Uruhande rwinyuma rwibanda cyane cyane kumikorere yarwo, rukeneye kuba rushobora guhuza ibipfunyika neza kugirango hirindwe kwinjira mu kirere cyo hanze, ubushuhe, nibindi, kugirango umutekano wifashe neza.

3. Ikoreshwa: Iyo ukoresheje firime ya kashe, birakenewe guhitamo neza impande zimbere ninyuma ukurikije ibisabwa. Kubipakira bikeneye gucapa ibirango cyangwa ibishushanyo, uruhande rwimbere rugomba gutoranywa nkuruhande rwo gucapa; kubipfunyika bigomba kunoza imikorere yikimenyetso, uruhande rwinyuma rugomba gutoranywa nkuruhande rukwiye.
