Iiplastiki zebakala lokutya zihlulwe zibe: PET (i-polyethylene terephthalate), i-HDPE (i-polyethylene ephezulu yoxinaniso), i-LDPE (i-polyethylene ephantsi), i-PP (i-polypropylene), i-PS (i-polystyrene), i-PC kunye nezinye iindidi.
I-PET (i-polyethylene terephthalate)
Ukusetyenziswa okuqhelekileyo: iibhotile zamanzi amaminerali, iibhotile zesiselo se-carbonated, njl.
Iibhotile zamanzi amaminerali kunye neebhotile zesiselo se-carbonated zenziwe ngale nto.Iibhotile zokusela azinakuphinda zisetyenziswe emanzini ashushu, kwaye le mathiriyeli iyakwazi ukumelana nobushushu ukuya kuma-70°C.Ilungele kuphela iziselo ezishushu okanye ezikhenkcezisiweyo, kwaye ikhubazeka ngokulula xa izaliswe lulwelo olunobushushu obuphezulu okanye ishushu, nezinto eziyingozi ebantwini eziphumayo.Ngaphezu koko, izazinzulu ziye zafumanisa ukuba emva kweenyanga ezili-10 zokusetyenziswa, le mveliso yeplastiki inokukhupha iicarcinogens eziyityhefu ebantwini.
Ngenxa yesi sizathu, iibhotile zokusela kufuneka zilahlwe xa zigqityiwe kwaye zingasetyenziswa njengeekomityi okanye izitya zokugcina ezinye izinto ukuphepha iingxaki zempilo.
I-PET yaqala ukusetyenziswa njengefayibha yokwenziwa, kunye nakwifilimu nakwiteyiphu, kwaye kuphela ngo-1976 yasetyenziswa kwiibhotile zesiselo.I-PET yayisetyenziswa njengesizalisi kwinto eyaziwa ngokuba 'yibhotile ye-PET'.
Ibhotile ye-PET inobunzima obugqwesileyo kunye nokuqina, ilula (kuphela i-1/9 ukuya kwi-1/15 yobunzima bebhotile yeglasi), kulula ukuyiphatha kunye nokusetyenziswa, idla amandla amancinci kwimveliso, kwaye ayiguquguquki, ayiguquguquki kwaye iyaxhathisa. kwiiasidi kunye neealkali.
Kwiminyaka yakutshanje, ibe yinto ebalulekileyo yokuzalisa iziphuzo ze-carbonated, iti, ijusi yesithelo, amanzi okusela apakishweyo, iwayini kunye ne-soy sauce, njl. Ukongeza, ii-agent zokucoca, i-shampoos, i-oyile yokutya, i-condiments, ukutya okumnandi, iziyobisi, izimonyo. , kunye neziselo ezinxilisayo zisetyenziswe ngamanani amaninzi kwiibhotile zokupakisha.
HDPE(iPolyethylene yoXinano oluPhezulu)
Ukusetyenziswa okuqhelekileyo: iimveliso zokucoca, iimveliso zokuhlamba, njl.
Izikhongozeli zePlastiki zokucoca iimveliso, iimveliso zokuhlambela, iingxowa zeplastiki ezisetyenziswa kwiivenkile ezinkulu kunye nodederhu lweevenkile ubukhulu becala zenziwe ngolu hlobo, zinokumelana nobushushu obuphezulu obuyi-110 ℃, eziphawulwe ngeengxowa zeplastiki zokutya zingasetyenziselwa ukubamba ukutya.Izikhongozeli zePlastiki zokucoca iimveliso kunye neemveliso zokuhlamba zingaphinda zisetyenziswe emva kokucoca ngononophelo, kodwa ezi zikhongozeli zihlala zingacocwa kakuhle, zishiya iintsalela zeemveliso zokucoca zantlandlolo, zijike zibe yindawo yokuzalela iibhaktheriya kunye nokucocwa okungaphelelanga, ngoko ke kungcono ukuba ungahlambuluki. zisetyenziswe ngokutsha.
I-PE yiplastiki esetyenziswa kakhulu kwishishini kunye nobomi, kwaye ngokuqhelekileyo ihlulwe ibe ziindidi ezimbini: i-polyethylene ephezulu (HDPE) kunye ne-polyethylene ephantsi (LDPE).I-HDPE ineqondo eliphezulu lokunyibilika kune-LDPE, inzima kwaye ixhathisa ngakumbi kukhukuliseko lolwelo oludlekayo.
I-LDPE ifumaneka kuyo yonke indawo kubomi banamhlanje, kodwa hayi ngenxa yezikhongozeli ezenziwe ngazo, kodwa ngenxa yeengxowa zeplastiki onokuzibona kuyo yonke indawo.Uninzi lweengxowa zeplastiki kunye neefilimu zenziwe nge-LDPE.
I-LDPE (iPolyethylene yoXinano oluphantsi)
Ukusetyenziswa okuqhelekileyo: ifilimu yokutya, njl.
Ifilimu yokutya, ifilimu yeplastiki, njl. Zonke zenziwe ngale nto.Ukumelana nobushushu akunamandla, ngokuqhelekileyo, ifilimu yokubambelela ye-PE kwiqondo lobushushu elingaphezulu kwe-110 ℃ iya kubonakala i-hot melt melt, iya kushiya umzimba womntu awukwazi ukubola i-agent yeplastiki.Kwakhona, xa ukutya kushushu kwifilimu yokutya, igrisi ekutyeni inokunyibilika ngokulula izinto eziyingozi kwifilimu.Ke ngoko, kubalulekile ukususa isigqubuthelo seplastiki ekutyeni kwi-microwave kuqala.
I-PP (ipolypropylene)
Ukusetyenziswa okuqhelekileyo: iibhokisi ze-microwave zesidlo sasemini
Iibhokisi ze-Microwave zesidlo sasemini zenziwe ngolu hlobo, oluxhathisayo kwi-130 ° C kwaye lungabonakali kakuhle.Le kuphela kwebhokisi yeplastiki enokufakwa kwi-microwave kwaye ingaphinda isetyenziswe emva kokucoca ngononophelo.
Kubalulekile ukuba uqaphele ukuba ezinye izitya ze-microwave zenziwe nge-PP 05, kodwa isiciko senziwe nge-PS 06, enokucaca kakuhle kodwa ayinakumelana namaqondo okushisa aphezulu, ngoko ayikwazi ukufakwa kwi-microwave kunye nesitya.Ukuze ube kwicala elikhuselekileyo, susa isiciko ngaphambi kokubeka isitya kwi-microwave.
I-PP kunye ne-PE kunokuthiwa ngabazalwana ababini, kodwa ezinye iimpawu zomzimba kunye nezomatshini zingcono kune-PE, ngoko ke abenzi beebhotile bahlala besebenzisa i-PE ukwenza umzimba webhotile, kwaye basebenzise i-PP ngobulukhuni obukhulu kunye namandla ukwenza i-cap kunye nokuphatha. .
I-PP inomlinganiselo ophezulu wokunyibilika we-167 ° C kwaye iyakwazi ukumelana nobushushu, kwaye iimveliso zayo ziyakwazi ukukhutshwa inzalo.Iibhotile eziqhelekileyo ezenziwe kwi-PP zinobisi lwe-soy kunye neebhotile zobisi zerayisi, kunye neebhotile ze-100% ye-juice yesithelo esicocekileyo, i-yogurt, iziphuzo zejusi, iimveliso zobisi (ezifana ne-pudding), njl. Izikhongozeli ezinkulu, ezifana neebhakethi, imigqomo, iisinki zokuhlambela impahla, iibhaskithi, iibhaskithi, njl., ubukhulu becala zenziwe kwiPP.
PS (polystyrene)
Ukusetyenziswa okuqhelekileyo: izitya zeebhokisi ze-noodle, iibhokisi zokutya okukhawulezayo
Izinto ezisetyenziselwa ukwenza izitya ze-noodle kunye ne-foam iibhokisi zokutya okukhawulezayo.Iyakwazi ukumelana nobushushu kunye nokubanda, kodwa ayikwazi ukufakwa kwi-oven microwave ukuphepha ukukhutshwa kweekhemikhali ngenxa yokushisa okuphezulu.Akufunekanga isetyenziselwe iiasidi ezomeleleyo (umz. ijusi yeorenji) okanye izinto zealkaline, njengoko i-polystyrene, engalunganga ebantwini, inokubola.Ke ngoko, kufuneka ukuphephe ukupakisha ukutya okushushu kwizikhongozeli zokutya okukhawulezayo kangangoko kunokwenzeka.
I-PS inokufunxeka kwamanzi aphantsi kwaye izinzile ngokomlinganiselo, ngoko inokufakwa inaliti, icinezelwe, ikhutshwe okanye ifakwe i-thermoformed.Inokuthi ifakwe inaliti, icofe ibunjwe, ikhutshwe kwaye ifakwe kwi-thermoform.Ngokuqhelekileyo ihlelwa njengenegwebu okanye engenagwebu ngokwendlela yokuba ikhe yahamba na inkqubo “yokuvuthuza”.
PCkunye nabanye
Ukusetyenziswa okuqhelekileyo: iibhotile zamanzi, iimagi, iibhotile zobisi
I-PC yinto esetyenziswa ngokubanzi, ngakumbi ekwenzeni iibhotile zobisi kunye neekomityi zendawo, kwaye iphikisana kuba iqulethe i-Bisphenol A. Iingcali zibonisa ukuba kwi-theory, nje ngokuba i-BPA i-100% iguqulelwe kwisakhiwo seplastiki ngexesha lokuveliswa kwemveliso. PC, kuthetha ukuba imveliso ngokupheleleyo BPA-free, singasathethi ke ukuba ayikhutshwa.Nangona kunjalo, ukuba inani elincinci le-BPA aliguqulwa libe kwisakhiwo seplastiki yePC, inokukhutshwa ibe kukutya okanye iziselo.Ngoko ke, kufuneka kuqwalaselwe ngakumbi xa usebenzisa ezi zitya zeplastiki.
Ukuphakama kweqondo lokushisa kwePC, ngakumbi i-BPA ikhutshwa kwaye ikhutshwe ngokukhawuleza.Ngoko ke, amanzi ashushu akufanele ahanjiswe kwiibhotile zamanzi zePC.Ukuba iketile yakho yinombolo 07, oku kulandelayo kunokunciphisa umngcipheko: Musa ukuyitshisa xa isetyenziswa kwaye ungayibeki esichengeni sokukhanya kwelanga.Musa ukuyihlamba iketile kumatshini wokuhlamba izitya.
Ngaphambi kokuyisebenzisa okokuqala, yihlambe ngesoda yokubhaka kunye namanzi afudumeleyo kwaye uyomise ngokwemvelo kwiqondo lokushisa.Kuyacetyiswa ukuba uyeke ukusebenzisa isikhongozeli ukuba sinawo nawaphi na amathontsi okanye ikhefu, njengoko iimveliso zeplastiki zinokugcina iibhaktheriya ngokulula ukuba zinomngxuma ocolekileyo.Kuphephe ukusebenzisa ngokuphindaphindiweyo izitya zeplastiki ezonakalisayo.
