Bonke abantu ezweni lethu basebenzisa izitsha ezilahlwayo, ngoba kubalulekile, ikakhulu ehlobo. Nokho, izitsha zasepulasitiki zavela eRussia nje nje nje. Namuhla imikhumbi yepulasitiki ikhona endlini yonke, nakuba bambalwa kakhulu abantu abazi ukuthi izinzuzo nezingozi zezinto zokupula epulasitiki zihluke kakhulu.
Izitsha zokupula epulasitiki
Izitsha zasePlastiki zikhulula umsikazi ngamunye ezinkingeni eziningi futhi ukhulula isikhathi sakhe, wenza ukuphila kube lula kakhulu futhi kube lula. Izinzuzo izitsha ziwusizo kakhulu. Izitsha ezinjalo zikhululekile futhi zilula, ziqine, ziqhathaniswa nesilazi noma izitsha ze-porcelain, kanye nokunye okubaluleke nakakhulu, lokhu akudingeki ukuthi kugezwe. Okokuqala kwavela izitsha zepulasitiki e-US, ekuqaleni kwekhulu lama-20. Konke kwaqala ngezinkomishi ezivamile zepulasitiki, bese izinkezo, amapuleti, amafoloko, imivese yaqala ukuvela.
Izitsha zokuqala ezilahlwa ezweni lethu zaziyizinkomishi ezivamile zephepha, kodwa izinga labo nokubukeka kwasala okufisa kakhulu. Ukuze uphuze ingilazi yekhofi noma itiye, kwadingeka ubeke ingilazi eyodwa kwenye, ukuze ungashiswa.
I-tableware yokulahlwa kwepulasitiki yokuphepha
Abaningi basanda kuba nesithakazelo ekuphepheni kwezingubo zokulahlwa kweplastiki, kuyini ukusetshenziswa nokulimala kwayo. Imibono ihluke ngokuphelele, kokubili okuhle nokubi. Kuze kube manje, izinhlobo eziningi zokudla okulahlwayo, ngoba kuyadingeka kakhulu. Uma uthenga izitsha, uqonda ngokucacile ukuthi uzoyisebenzisa yini. Izitsha zokudlela kanye nekhishini yizi: izindebe, izibuko, amachiza, ukusika, amabhodlela amanzi, ama-flasks, iziqukathi zamaswidi, ukupakisha ukugcina noma yimiphi imikhiqizo, i-tablecloths elahlayo, ama-wrappers, napkins.
Izitsha ezilahla zasetshenziswa yiwo wonke umuntu, kodwa akubona bonke abaqaphela izici zezitsha. Isibonelo, abaningi abazi ukuthi akuzona zonke izibuko ezifanele iziphuzo ezishisayo. Amalazi akhiwe avela ku-polystyrene awafanelekile lokhu, ngoba akakwazi ukubhekana namazinga aphezulu okushisa nokukhishwa kwe-toxini ibe ikhofi noma itiye. Kungcono ukuphuza iziphuzo ezishisayo ezinkomeni ze-polypropylene, yizona ezizinzile kunazo zonke, kodwa iziphuzo ezidakayo azikwazi ukuthululwa kuzo noma enye. Uma kungenjalo, ungalimaza izinso nesibindi, futhi ungonakalise kakhulu umbono.
I-tabletware etholakalayo epulasitiki
Izinto eziningi nezinto ezenziwe ngepulasitiki, zivame kakhulu. Bonke abantu basebenzisa izitsha zepulasitiki, kodwa kufanele kuqashelwe ukuthi inkinga yokusetshenziswa iyinto enzima kakhulu. Ipulasitiki ayinayo impahla yokubola, akunakwenzeka ukuyishisa, futhi uma kungenayo i-janitors ne-scavengers okwanele emigwaqweni, izinto ze-plastic zivula imigwaqo yamadolobha zibe yilala. Ipulasitiki yinto ebizwa nge-polymeric, yenziwe ngezinto ezinjalo ezingahlangani nama-acids, amafutha, ukudla.
Ukulimala izitsha
Akuwona wonke ama-molecule enqubo ye-polymerization afinyelela usayizi obuthile oyifunayo, ahlala esebenzayo, futhi aphume ezidlweni kuwo wonke okuqukethwe kwawo, bese engena emzimbeni. Inqubo enjalo iyohamba ngokushesha uma ufaka ukudla okushisayo endishini noma uthele itiye elishisayo.
Imikhiqizo eminingi kakhulu eyenziwe ngepulasitiki, iqukethe izilonda, eziyingozi kakhulu, izinto ezinobuthi, usawoti wensimbi enzima. Futhi kubalulekile ukuthi uqaphele ukuthi konke lokhu kungena emzimbeni wethu uma kushiswa. Ngakho-ke, izitsha ezilahlwayo akufanele zisetshenziswe noma ngabe yikuphi.
Futhi kukhona i-tableware elahlwayo eyenziwe nge-styrene ne-acrylic, kubiza ngempela okungabizi kahle futhi kungenakudilizwa. Izitsha ezinjalo azikhuthazwa ukuthi zisetshenziswe kuhhavini ye-microwave, noma kunjalo zingagcwa ngokuphepha ku-daishisher, noma ngesandla.
I-polypropylene yinto engabizi kakhulu, izinto zalezi zinto zingakwazi ukumelana kuze kube yi-100 ° C. Ngokuvamile zisetshenziselwa amaqembu, izithombe ze-picnic, kuvunyelwe ukuba zihlanjwe kuma-daishisher, kodwa kungcono. Izitsha ezinjalo zisetshenziswe kahle kuhhavini ye-microwave.
I-oven microwave nayo isebenzisa izitsha ze-polycarbonate. Ingahlanzwa ngokukhululekile, njengoba inamandla kakhulu. Ngakho-ke, futhi impahla iyabiza kunanoma yiziphi ezinye izitsha. Kulesi sihloko akugcini nje kuphela amapulethi nama-mugs, kodwa futhi nezibuko zokuphuza utshwala. Abakhiqizi abadume kakhulu yizinkampani: Strahl, Tuffex, Tervis Tumbler. Baqinisekisa ikhwalithi yemikhiqizo eyenziwe, izitsha zabo zibiza ngokuphindwe kabili kunezitsha ezivamile ezilahlayo, ngoba izinga lihle kakhulu.
Kukhona isidlo esenziwe ngento efana ne-melamine. Yisisetshenziswa esisetshenziswa embonini yamakhemikhali. Kulo, kutholakala uhlobo lwe-resine formaldehyde. Lesi sitsha ngokuvamile siqukethe i-formaldehyde, futhi kaningi kakhulu, futhi siyingozi kakhulu emzimbeni womuntu, futhi kufanele kuqashelwe ukuthi inani lale mali lidlula amashumi avunyelwe. Izitsha ezinjalo ziyingozi kakhulu. I-Melamine substance emzimbeni womuntu ithinta kabi kakhulu, futhi abakhiqizi bayo bayakwazi ukungeza kuwo njengama-asbestos amandla, into eseyeke ukusetshenziselwa kuzo zonke izimboni ezaziwayo. Lesi sici singabangela ukuthuthukiswa komdlavuza, ngakho-ke kudingeka uqaphele ngokucophelela ngokuthi ungubani uhlobo lwezitsha ozisebenzisa.
