Kule mihla, abantu bayixhalabele kakhulu impilo yabo. Abanye abantu bahlala bebona iingxelo zeendaba zokuba abanye abantu abatya i-takeout ixesha elide basengozini yeengxaki zempilo. Ngoko ke, ngoku abantu baxhalabile kakhulu malunga nokuba iingxowa zeplastiki ziyiplastiki yokutya kunye nokuba ziyingozi kwimpilo yabo. Nazi iindlela ezimbalwa zokwahlula phakathi kweengxowa zeplastiki zokutya kunye neeplastiki eziqhelekileyo.
Kukulungele ukusebenzisa iiplastiki zokutya kunye nezinye izinto. Okwangoku, kukho iintlobo ezimbini zeengxowa zeplastiki kwimarike, enye yenziwe ngezinto ezifana ne-polyethylene, ekhuselekileyo kwaye ingasetyenziselwa ukupakisha ukutya, kwaye enye iyityhefu, enokuba yingozi ekupakisheni ukutya kwaye ingaba kuphela. isetyenziselwa ukupakisha ngokubanzi.
Iingxowa zokupakisha ukutyangokuqhelekileyo zaziwa kuthi njengeengxowa zebakala lokutya, apho kukho imigangatho engqongqo kunye nephezulu yemathiriyeli yazo. Siqhele ukusebenzisa imathiriyeli yebakala lokutya ngokuqhelekileyo ayinayo ityhefu, ifilimu ehambelana nokusingqongileyo njengeyona nto iphambili. Kwaye izinto eziluhlaza ezahlukeneyo zineempawu ezahlukeneyo, ngoko kufuneka sikhethe ngokweempawu zokutya ngokwazo ngexesha lokwenziwa.
Loluphi uhlobo lweengxowa zeplastiki ezikwibakala lokutya?
I-PE yi-polyethylene, kunye neengxowa zeplastiki ze-PE zibakala lokutya. I-PE luhlobo lwe-resin ye-thermoplastic eyenziwe nge-ethylene nge-polymerization. Ayinavumba kwaye ayinayo ityhefu, kwaye inokumelana nobushushu obuphantsi kakhulu (elona qondo lobushushu lisezantsi liyi-100 ~ 70℃). Inozinzo oluhle lweekhemikhali, i-asidi kunye nokumelana ne-alkali, kwaye ayinyibiliki kwi-solvents eziqhelekileyo kwiqondo lokushisa eliqhelekileyo. Ine-insulation egqwesileyo yombane kunye nokufunxa amanzi aphantsi. Iingxowa zeplastiki zodidi lokutya ngokubanzi zohlulwe zibe ziingxowa zokupakisha ukutya eziqhelekileyo, iingxowa zokupakisha ukutya ezifunxayo, iingxowa zokupakisha ukutya ezivuthekayo, iingxowa zokupakisha ukutya okubilisiweyo, iingxowa zokupakisha ukutya okubilisiweyo, iingxowa zokupakisha ukutya ezisebenzayo njalo njalo, ngezinto ezahlukeneyo. Iingxowa zeplastiki eziqhelekileyo zokutya ziquka i-PE (i-polyethylene), i-aluminium foil, inayiloni kunye nezinto ezidibeneyo. Iingxowa zeplastiki zodidi lokutya zineempawu ezifanayo ukuze kuqinisekiswe ukuba ukutya kukutsha kwaye akunazifo nokubola. Enye kukuthintela ngokupheleleyo i-organic solvent, igrisi, igesi, umphunga wamanzi njalo njalo; Enye kukuba nokumelana okugqwesileyo kokungena, ukuxhathisa ukufuma, ukumelana nokubanda, ukumelana nobushushu, ukuphepha ukukhanya kunye nokugquma, kwaye ube nenkangeleko entle; Eyesithathu kulula ukwenza kunye neendleko eziphantsi zokulungisa; Okwesine kukuba namandla amahle, iingxowa zokupakisha zeplastiki zinomsebenzi ophezulu wamandla ngeyunithi nganye, zinempembelelo kwaye kulula ukuyiguqula.
Iingxowa zeplastiki zokutya kunye neeplastiki eziqhelekileyo zokuchonga indlela
Indlela yokujonga umbala, iingxowa zeplastiki ezikhuselekileyo zihlala zimhlophe qhwa, ziguquguqukayo, le plastiki iya kuziva ithambisa, ivakale ngathi umphezulu we-wax, kodwa umbala weengxowa zeplastiki ezinetyhefu ngokubanzi ziyi-hamster emthubi, uzive uncangathi kancinane.
Indlela yokuntywiliselwa emanzini, ungabeka ingxowa yeplastiki emanzini, ulinde ixesha elithile ukuba uyeke, uya kufumana etshone emazantsi eengxowa zeplastiki ezinetyhefu, okwahlukileyo kukhuselekile.
Indlela yomlilo. Iiplastiki ezikhuselekileyo kulula ukuzitshisa. Xa bevutha, baya kuba nedangatye eliluhlaza njengeoli yekhandlela, kukho ivumba leparafini, kodwa umsi omncinci kakhulu. Kwaye iingxowa zeplastiki ezinobuthi azinakutsha, ilangatye liphuzi, ukutshisa kunye nokunyibilika kuya kukhupha i-silika, kuya kuba nephunga elicasulayo njenge-hydrochloric acid.
Indlela yokuvumba. Ngokuqhelekileyo, izikhwama zeplastiki ezikhuselekileyo azikho iphunga elingaqhelekanga, ngokuchaseneyo, kukho i-pungent, iphunga elimnandi, elinokuthi libe ngenxa yokusetyenziswa kwezinye izongezo okanye umgangatho ombi.
