Namuhla, abantu bakhathazeke kakhulu ngempilo yabo. Abanye abantu bavame ukubona imibiko yezindaba yokuthi abanye abantu abadla i-takeout isikhathi eside bathambekele ezinkingeni zempilo. Ngakho-ke, manje abantu bakhathazeke kakhulu ngokuthi izikhwama zepulasitiki ziyizikhwama zepulasitiki zokudla nokuthi ziyingozi yini empilweni yabo. Nazi izindlela ezimbalwa zokuhlukanisa phakathi kwezikhwama zepulasitiki zokudla kanye nezikhwama zepulasitiki ezijwayelekile.
Kuyinto elula ukusebenzisa izikhwama zepulasitiki ukudla nezinye izinto. Njengamanje, kunezinhlobo ezimbili zezikhwama zepulasitiki emakethe, eyodwa yenziwe ngezinto ezifana ne-polyethylene, ephephile futhi engasetshenziswa ukupakisha ukudla, kanti enye inobuthi, okungaba yingozi ekufakweni kokudla futhi kungaba kuphela esetshenziselwa ukupakisha okuvamile.
Izikhwama zokupakisha ukudlangokuvamile zaziwa kithi njengezikhwama zebanga lokudla, okunezindinganiso eziqinile neziphakeme zezinto zazo. Izinto ezisetshenziswa kakhulu ezisezingeni lokudla ngokuvamile azinabo ubuthi, ifilimu ehambisana nemvelo njengento esemqoka. Futhi izinto zokusetshenziswa ezihlukile zinezici ezihlukile, ngakho-ke kufanele sikhethe ngokuya nezici zokudla uqobo ngesikhathi sokukhiqiza.
Hlobo luni lwezikhwama zepulasitiki ezisezingeni lokudla?
I-PE iyi-polyethylene, kanti izikhwama zepulasitiki ze-PE ziyizinga lokudla. I-PE iwuhlobo lwe-thermoplastic resin eyenziwe nge-ethylene ngokusebenzisa i-polymerization. Ayinaphunga futhi ayinabo ubuthi, futhi inokumelana okuhle kakhulu nezinga lokushisa eliphansi (izinga lokushisa eliphansi kakhulu lokusebenza ngu -100 ~ 70 ℃). Inokuqina okuhle kwamakhemikhali, ukumelana ne-asidi ne-alkali, futhi ayincibiliki ezincibilikisini ezivamile ezingeni lokushisa elivamile. Ine-insulation kagesi enhle kakhulu kanye nokumunca amanzi aphansi. Izikhwama zepulasitiki ezisezingeni lokudla zivame ukuhlukaniswa zibe izikhwama ezijwayelekile zokupakisha ukudla, izikhwama zokupakisha ukudla ezifuthayo, izikhwama zokufaka ukudla eziphephukayo, izikhwama zokufaka ukudla okuphekiwe, izikhwama zokupakisha ukudla okubilisiwe, izikhwama zokupakisha ukudla ezisebenzayo nokunye, ngezinto ezahlukahlukene. Izikhwama zepulasitiki zebanga lokudla ezivamile zihlanganisa i-PE (i-polyethylene), ucwecwe lwe-aluminium, inayiloni nezinto eziyinhlanganisela. Izikhwama zepulasitiki ezisezingeni lokudla zinezici ezithile ezivamile ukuze kuqinisekiswe ukuthi ukudla kusha futhi akunazifo nokubola. Enye iwukuvimba ngokuphelele i-organic solvent, igrisi, igesi, umhwamuko wamanzi nokunye; Enye iwukuba nokumelana okuhle kakhulu kokungena, ukumelana nomswakama, ukumelana nokubanda, ukumelana nokushisa, ukugwema ukukhanya nokwahlukanisa, futhi ibe nokubukeka okuhle; Okwesithathu kulula ukwakha kanye nezindleko eziphansi zokucubungula; Okwesine ukuba namandla amahle, izikhwama zokupakisha zepulasitiki zinamandla aphezulu ngeyunithi ngayinye yesisindo, azikwazi ukumelana nomthelela futhi kulula ukuzishintsha.
Izikhwama zepulasitiki zokudla kanye nezikhwama zepulasitiki ezijwayelekile ukuhlonza indlela
Indlela yokubuka umbala, izikhwama zepulasitiki eziphephile ngokuvamile zimhlophe njenge-milky, zishintshashintsha, lepulasitiki izozizwa igcotshiwe, izwakale sengathi ingaphezulu liyingcina, kodwa umbala wezikhwama zepulasitiki ezinobuthi ngokuvamile uphuzi, uzizwa unamathele kancane.
Indlela yokucwiliswa kwamanzi, ungafaka isikhwama sepulasitiki emanzini, ulinde isikhashana ukuze uhambe, uzothola izikhwama zepulasitiki ezinobuthi zicwile emanzini, okuphambene kuphephile.
Indlela yomlilo. Izikhwama zepulasitiki eziphephile kulula ukuzishisa. Lapho zivutha, zizoba nelangabi eliluhlaza okwesibhakabhaka njengamafutha ekhandlela, kunephunga likapharafini, kodwa intuthu encane kakhulu. Futhi izikhwama zepulasitiki ezinobuthi azikwazi ukuvutha, ilangabi liphuzi, ukuvutha nokuncibilika kuzokhipha usilika, kuyoba nephunga elicasulayo njenge-hydrochloric acid.
Indlela yokuhogela. Ngokuvamile, izikhwama zepulasitiki eziphephile azinayo iphunga elingavamile, ngokuphambene nalokho, kukhona iphunga elimnandi, elimnandi, elingase libe ngenxa yokusetshenziswa kwezinye izithasiselo noma izinga elibi.
