Iyi ni ishyirwa mu byiciro mpuzamahanga bya pulasitiki. Imibare itandukanye igaragaza ibikoresho bitandukanye. Impandeshatu izengurutswe n'imyambi itatu igaragaza ko pulasitiki yo mu rwego rw'ibiribwa ikoreshwa. Inyuguti "5″ muri mpandeshatu na "PP" munsi ya mpandeshatu bigaragaza pulasitiki. Igicuruzwa gikozwe mu bikoresho bya polypropylene (PP). Ibikoresho ni byiza kandi ntibigira uburozi. Icy'ingenzi kurushaho, gifite ubushobozi bwo kwihanganira ubushyuhe bwinshi kandi kidahinduka. Ni ibikoresho bya pulasitiki bishobora gushyirwa mu itanura rya microwave
Hari ubwoko 7 bw'amakode yo gushyira ibimenyetso ku bicuruzwa bya pulasitiki. Muri ubwo bwoko 7, hari ubwa 5 gusa, ari nabwo bwonyine bushobora gushyushywa mu itanura rya microwave. Kandi ku masahani yihariye y'ibirahure bya microwave afite imipfundikizo n'amasahani ya ceramic afite imipfundikizo, ikirango cya polypropylene PP nacyo kigomba gushyirwaho ikimenyetso.
Imibare iri hagati ya 1 na 7, igaragaza ubwoko butandukanye bwa pulasitiki, kandi amacupa yacu asanzwe y’ibinyobwa, umutobe w’imbuto, soda irimo karubone n’andi macupa y’ibinyobwa akoresha “1″, ni ukuvuga PET, ifite plasticity nziza, ibonerana cyane, kandi idashobora kwihanganira ubushyuhe. Biroroshye guhindura no kurekura ibintu byangiza iyo birengeje 70°C.
“No. 2″ HDPE ikunze gukoreshwa mu macupa yo kwiyuhagira, byoroshye korora bagiteri kandi ntikwiriye gukoreshwa igihe kirekire.
“3″ ni PVC isanzwe cyane, ifite ubushyuhe bwinshi bwo kwirinda bwa dogere selisiyusi 81.
“LDPE ya 4″ ikunze gukoreshwa mu gipfunyika cya pulasitiki, kandi ubushyuhe bwayo ntibugira imbaraga. Ikunze gushonga kuri 110°C, bityo agapfukamunwa kagomba gukurwaho iyo ushyushya ibiryo.
Ibikoresho bya PP bya "5″ ni pulasitiki yo mu rwego rwo hejuru, impamvu ni uko ishobora gucukurwa mu buryo butaziguye hatabayeho kongeramo ibindi bintu byangiza, kandi ishobora kwihanganira ubushyuhe bwinshi bwa 140°C. Ikoreshwa by'umwihariko mu ziko rya mikoroonde. Amacupa menshi y'abana n'udusanduku tw'amafunguro dushyuha bikozwe muri ibi bikoresho.
Icyitonderwa ni uko kuri bimwe mu dusanduku twa mikoroonde, agasanduku gakozwe muri No. 5 PP, ariko agapfundikizo gakozwe muri No. 1 PE cyangwa PS (amabwiriza rusange y'ibicuruzwa azabivuga), bityo ntibishobora gushyirwa mu itanura rya mikoroonde hamwe n'agasanduku.
“6″ PS ni yo bikoresho by'ingenzi byo gusohora ifuro ku meza. Ntibikwiriye aside ikomeye na alkali, kandi ntibishobora gushyushywa mu itanura rya mikoroonde.
Plastike ya "7″ irimo izindi plastiki zitari 1-6.
Urugero, hari abantu bakunda gukoresha amacupa y’amazi akomeye cyane yo mu bwoko bwa siporo. Mu bihe byashize, ahanini yabaga akozwe muri mudasobwa ya pulasitiki. Icyanenzwe ni uko arimo ikintu cy’inyongera cya bisphenol A, gitera imikorere y’imisemburo kandi gisohoka byoroshye hejuru ya dogere selisiyusi 100. Amwe mu masosiyete azwi cyane yashyizeho ubwoko bushya bw’izindi plastiki kugira ngo akore ibikombe by’amazi, kandi buri wese agomba kubyitondera.
Umufuka w'ibiribwa bishyushye wo mu bwoko bwa vacuum cleaner, umufuka w'ibiribwa wo mu bwoko bwa micro-onde wo mu ipaki ikonjeshejwe, ubushyuhe bwinshi, RTE, umufuka w'ibiribwa usanzwe ukorwa muri PET/RCPP cyangwa PET /PA/RCPP
Bitandukanye n'izindi paki zisanzwe za pulasitiki zikozwe muri lamiant, paki ya Microwavable igizwe na Polyester Film yihariye itwikiriwe na Alumina (AIOx) nk'urwego rwayo rwo kurinda aho kuba urw'urwego rusanzwe rwa aluminiyumu. Ituma paki ishyushya yose muri microweve mu gihe ibuza umuriro w'amashanyarazi kubaho. Ifite ubushobozi bwo kwiha umwuka, paki ya Microwavable ifasha abayikoresha mu gihe cyo gutegura ibiryo mu gukuraho ikibazo cyo gusiga imyobo iyo ari yo yose mu paki iyo bashyushya ibiryo muri microweve.
Imifuka ihagarara yemerera abakiriya kurya ibiryo byabo nta mpamvu yo koza amasahani cyangwa amasahani. Umufuka wa Microwave ushobora gukoreshwa mu gucapa amashusho yihariye, wemerera amasosiyete kwerekana ikirango cyabo n'amakuru y'ibicuruzwa byabo.
Nyamuneka ohereza ikibazo cyawe ku buntu. Tuzaguha ibisobanuro birambuye kugira ngo urebe niba hari icyo wakwitaho.
