Kulezi zinsuku, abantu bakhathazeke kakhulu ngempilo yabo. Abanye abantu bavame ukubona izindaba zibika ukuthi abanye abantu abadla isikhathi eside bathambekele ezinkingeni zempilo. Ngakho-ke, manje abantu bakhathazekile kakhulu ngokuthi izikhwama zepulasitiki ziyizikhwama zepulasitiki zokudla nokuthi ziyingozi empilweni yazo. Nazi izindlela ezimbalwa indlela yokuhlukanisa phakathi kwezikhwama zepulasitiki zokudla nezikhwama zepulasitiki ezijwayelekile.
Kuyinto elula ukusebenzisa izikhwama zepulasitiki zokudla nezinye izinto. Njengamanje, kunezinhlobo ezimbili zezikhwama zepulasitiki emakethe, enye yenziwe ngezinto ezifana ne-polyethylene, ephephile futhi ingaba yingozi ekuphaketheni ukudla futhi kuphela okusetshenziselwa ukufakwa okujwayelekile.
Izikhwama zokufaka ukudlaNgokuvamile zizaziwa nathi njengezikhwama zebanga lokudla, lapho kunezindinganiso eziqinile neziphezulu zezinto zazo. Ngokuvamile sisebenzisa izinto ebangeni lokudla ngokuvamile akuyona ingozi, ifilimu enobungane yemvelo njengezinto eziphambili. Futhi izinto ezahlukene ezingavuthiwe zinezici ezihlukile, ngakho-ke kufanele sikhethe ngokuya ngezimpawu zokudla uqobo ngesikhathi sokwenza.
Uhlobo luni lwezikhwama zepulasitiki ibanga lokudla?
I-polyethylene, kanye nezikhwama zepulasitiki zepulasitiki zibanga lokudla. I-PE luhlobo lwe-thermoplastic resin eyenziwe nge-ethylene nge-polymerization. Kuyinto engenamandla futhi ayinobuthi, futhi inokumelana okuhle kakhulu kwezinga lokushisa (izinga lokushisa eliphansi kakhulu lingu -100 ~ 70 ℃). Inokuqina okuhle kwamakhemikhali, i-acid kanye ne-alkali yokumelana, futhi iyakhohlisa izixazululo ezijwayelekile ekushiseni okujwayelekile. Inomfaki omuhle kakhulu kagesi kanye nokutholwa kwamanzi okuphansi. Izikhwama zepulasitiki zebanga lokudla zihlukaniswe izikhwama ezijwayelekile zokupakisha ukudla, izikhwama zokupakisha zokudla ezivuthayo, izikhwama zokupakisha zokudla ezivukile, izikhwama zokupakisha zokudla ezibilisiwe, izikhwama zokupakisha zokudla ezibilisiwe, izikhwama ezahlukahlukene zokupakisha nokunye, ngezinto ezahlukahlukene. Izikhwama zepulasitiki ezivamile zebanga lokudla zifaka i-PE (Polyethylene), i-aluminium foil, i-nylon kanye nezinto ezihlanganisiwe. Izikhwama zepulasitiki zebanga lokudla zinezici ezithile ezijwayelekile ukuze kuqinisekiswe ukuthi ukudla kusha futhi kukhululekile ezifweni nasekuboleni. Eyodwa ukugwema ngokuphelele i-organic solvent, i-grease, igesi, umphunga wamanzi nokunye; Okunye ukuba nokumelana okuhle kakhulu kokuvumelanisa, ukumelana komswakama, ukumelana nokubanda, ukumelana nokushisa, ukugwema ukukhanya nokufakelwa, futhi kube nokubukeka okuhle; Okwesithathu kulula ukwakha nezindleko eziphansi; Okwesine kufanele kube namandla amahle, izikhwama zokupakisha zepulasitiki zinokusebenza okuphezulu kwamandla ngesisindo ngasinye seyunithi, kuvimbela umthelela futhi kulula ukuguqula.
Izikhwama zepulasitiki zokudla kanye nezikhwama ezijwayelekile zepulasitiki ukukhomba indlela
Indlela yokubuka yombala, izikhwama zepulasitiki zokuphepha zivame ukumhlophe ezimhlophe, ziguqulwe, lolu moya luzozizwa sengathi ingaphezulu le-wax, kepha umbala wezikhwama zepulasitiki ezinobuthi ngokuvamile u-hamster ophuzi, uzizwe unamathela kancane.
Indlela yokucwilisa amanzi, ungabeka isikhwama sepulasitiki emanzini, linda isikhashana ukuyeka, uzothola ukushona phansi kwamanzi kunezikhwama zepulasitiki ezinobuthi, okuphambene kuphephile.
Indlela yomlilo. Izikhwama zepulasitiki eziphephile kulula ukuzishisa. Lapho bevutha, bayoba nelangabi eliluhlaza okwesibhakabhaka njengamafutha, kunephunga likaphalafini, kepha intuthu encane kakhulu. Futhi izikhwama zepulasitiki ezinobuthi azivuli, ilangabi liphuzi, livutha futhi lincibilika lizokhipha usilika, kuzoba nephunga elicasulayo njenge-hydrochloric acid.
Indlela iphunga. Ngokuvamile, izikhwama zepulasitiki eziphephile azinalo iphunga elingajwayelekile, ngokuphambene nalokho, kunephunga le-pungent, nenukatha, okungenzeka ngenxa yokusebenzisa ezinye izengezo noma ikhwalithi engeyinhle.
