Kubomi bethu bemihla ngemihla, iibhotile zeplastiki zingabonwa yonke indawo.Ndiyazibuza ukuba uphawule ukuba kukho uphawu lwamanani olubunjwe njengophawu olunxantathu ezantsi kwiibhotile ezininzi zeplastiki (iikomityi).
umzekelo:
Iibhotile zamanzi amaminerali, eziphawulwe 1 phantsi;
Iikomityi zeplastiki ezikwazi ukumelana nobushushu zokwenza iti, eziphawulwe ngo-5 phantsi;
Izitya ze-noodle ezikhawulezayo kunye neebhokisi zokutya okukhawulezayo, izantsi libonisa i-6;
…
Njengoko wonke umntu uyazi, iileyibhile ezisezantsi kwezi bhotile zeplastiki zineentsingiselo ezinzulu, eziqulethe "ikhowudi yetyhefu" yeebhotile zeplastiki kwaye imele ububanzi bokusetyenziswa kweemveliso zeplastiki ezihambelanayo.
"Amanani kunye neekhowudi ezisezantsi kwebhotile" ziyinxalenye yokuchongwa kwemveliso yeplastiki echazwe kwimigangatho yesizwe:
Isimboli sikanxantathu esiphinda sisetyenziswe phantsi kwebhotile yeplastiki sibonisa ukuphinda sisetyenziswe, kwaye amanani 1-7 abonisa uhlobo lwe-resin esetyenziswe kwiplastiki, okwenza kube lula kwaye kulula ukuchonga izinto eziqhelekileyo zeplastiki.
"1" PET - i-polyethylene terephthalate
Ingaba ikomityi yeplastiki oyiselayo inetyhefu?Jonga nje amanani asezantsi kwaye ufumanise!
Esi sixhobo simelana nobushushu ukuya kuma-70 ° C kwaye sifanelekile kuphela ukubamba iziselo ezifudumeleyo okanye ezikhenkcezisiweyo.Ikhubazeka ngokulula xa izaliswe lulwelo olunobushushu obuphezulu okanye ishushu, kwaye izinto eziyingozi kumzimba womntu zinokunyibilika;ngokubanzi iibhotile zamanzi amaminerali kunye neebhotile zesiselo se-carbonated zenziwe ngale nto.
Ke ngoko, kucetyiswa ngokubanzi ukuba ulahle iibhotile zesiselo emva kokusetyenziswa, ungaphindi uzisebenzise, okanye uzisebenzise njengezikhongozeli zokugcina ukubamba ezinye izinto.
"2" HDPE - polyethylene yoxinaniso oluphezulu
Ingaba ikomityi yeplastiki oyiselayo inetyhefu?Jonga nje amanani asezantsi kwaye ufumanise!
Esi sixhobo sinokumelana nobushushu obuphezulu be-110 ° C kwaye sihlala sisetyenziselwa ukwenza iibhotile zamayeza amhlophe, izinto zokucoca, kunye nezikhongozeli zeplastiki kwiimveliso zokuhlambela.Uninzi lweengxowa zeplastiki ngoku ezisetyenziswa kwiivenkile ezinkulu ukubamba ukutya nazo zenziwe ngale nto.
Olu hlobo lwesikhongozeli alulula ukusicoca.Ukuba ukucocwa akucokisekanga, izinto zokuqala ziya kuhlala kwaye akukhuthazwa ukuba zihlaziywe.
“3″ PVC – polyvinyl chloride
Ingaba ikomityi yeplastiki oyiselayo inetyhefu?Jonga nje amanani asezantsi kwaye ufumanise!
Esi sixhobo siyakwazi ukumelana nobushushu obuphezulu obuyi-81°C, sineplastiki egqwesileyo, kwaye sixabiso eliphantsi.Kulula ukuvelisa izinto ezinobungozi kumaqondo aphezulu kwaye zide zikhutshwe ngexesha lokwenziwa kwemveliso.Xa izinto eziyityhefu zingena emzimbeni womntu ngokutya, zinokubangela umhlaza wamabele, iziphene zokuzalwa kubantwana abasandul’ ukuzalwa nezinye izifo..
Okwangoku, le nto isetyenziswa ngokuqhelekileyo kwii-raincoats, izinto zokwakha, iifilimu zeplastiki, iibhokisi zeplastiki, njl., kwaye ayifane isetyenziswe ukupakisha ukutya.Ukuba isetyenzisiwe, qiniseka ukuba ungayivumeli ibe shushu.
"4" i-LDPE - i-polyethylene yoxinaniso oluphantsi
Ingaba ikomityi yeplastiki oyiselayo inetyhefu?Jonga nje amanani asezantsi kwaye ufumanise!
Olu hlobo lwezinto eziphathekayo alukho ukumelana nobushushu obuqinileyo kwaye lusetyenziswa kakhulu kwimveliso yefilimu yokutya kunye nefilimu yeplastiki.
Ngokuqhelekileyo, ifilimu yokubambelela ye-PE efanelekayo iya kunyibilika xa izinga lokushisa lidlula i-110 ° C, lishiya amanye amalungiselelo eplastiki angenako ukuchithwa ngumzimba womntu.Ngaphezu koko, xa ukutya kuhlanganiswe kwifilimu yokutya kwaye kushushu, ioli ekutya iya kunyibilika ngokulula kwifilimu yokutya.izinto eziyingozi zinyibilika.
Ngoko ke, kucetyiswa ukuba ukutya okusongelwe ngeplastiki kufuneka kususwe ngaphambi kokuba kufakwe kwi-oven microwave.
"5" PP - polypropylene
Ingaba ikomityi yeplastiki oyiselayo inetyhefu?Jonga nje amanani asezantsi kwaye ufumanise!
Esi sixhobo, esiqhele ukusetyenziselwa ukwenza iibhokisi zesidlo sasemini, siyakwazi ukumelana namaqondo obushushu obuphezulu obuyi-130°C kwaye asinakucaca kakuhle.Yibhokisi yeplastiki kuphela enokufakwa kwi-oven microwave kwaye ingaphinda isetyenziswe emva kokucoca ngokucokisekileyo.
Nangona kunjalo, kufuneka kuqatshelwe ukuba ezinye iibhokisi zesidlo sasemini zinophawu "5" emazantsi, kodwa "6" uphawu kwisiciko.Kule meko, kucetyiswa ukuba isivalo sisuswe xa ibhokisi lesidlo sasemini lifakwe kwi-oven microwave, kwaye kungekhona kunye nomzimba webhokisi.Beka kwi-microwave.
“6″ PS——Ipolystyrene
Ingaba ikomityi yeplastiki oyiselayo inetyhefu?Jonga nje amanani asezantsi kwaye ufumanise!
Olu hlobo lwezinto eziphathekayo lunokumelana nokushisa kwama-70-90 degrees kwaye lunokucaca kakuhle, kodwa alukwazi ukufakwa kwi-oven microwave ukuphepha ukukhutshwa kweekhemikhali ngenxa yokushisa okugqithisileyo;kunye nokubamba iziselo ezishushu kuya kuvelisa i-toxins kunye nokukhulula i-styrene xa itshisiwe.Ihlala isetyenziselwa ukuveliswa kweMathiriyeli yeebhokisi ze-noodle zohlobo lwesitya kunye neebhokisi zokutya okukhawulezayo.
Ngoko ke, kucetyiswa ukuba ugweme ukusebenzisa iibhokisi zokutya okukhawulezayo ukupakisha ukutya okutshisayo, okanye ukuzisebenzisa ukubamba i-acids eqinile (njengejusi ye-orenji) okanye izinto ezinamandla zealkaline, kuba ziya kubola i-polystyrene engafanelekanga kumzimba womntu kwaye iyakwazi. lula ukwenza umhlaza.
"7"Abanye - iPC kunye nezinye iikhowudi zeplastiki
Ingaba ikomityi yeplastiki oyiselayo inetyhefu?Jonga nje amanani asezantsi kwaye ufumanise!
Le yimathiriyeli esetyenziswa kakhulu, ngakumbi xa kusenziwa iibhotile zeentsana, iikomityi zasemkhathini, njl.ngoko ke, qaphela kwaye uhlawule ingqalelo ekhethekileyo xa usebenzisa le nto yeplastiki.
Ke, emva kokuqonda iintsingiselo ezifanelekileyo zezi lebhile zeplastiki, indlela yokuqhekeza “ikhowudi yetyhefu” yeeplastiki?
Iindlela ezi-4 zokubona ubutyhefu
(1) Uvavanyo lweemvakalelo
Iingxowa zeplastiki ezingezizo zinetyhefu zimhlophe ngobisi, ziguquguqukayo, okanye azinambala kwaye ziyabonakala, zibhetyebhetye, zigudileyo xa zibamba, kwaye zibonakala zinewax phezu komhlaba;Iingxowa zeplastiki ezinetyhefu zimdaka okanye zityheli ngombala kwaye zivakala zincangathi.
(2) Ukufunyanwa kweJitter
Thatha isiphelo esinye sengxowa yeplastiki kwaye uyishukumise ngamandla.Ukuba ithe yavakalisa isandi esibukhali, ayibi buhlungu;ukuba ithe yenza isandi esiphantsi, iyityhefu.
(3) Uvavanyo lwamanzi
Beka isikhwama seplastiki emanzini kwaye uyicinezele ukuya ezantsi.Ingxowa yeplastiki engeyotyhefu inomxhuzulane othile omncinci kwaye inokudada ngaphezulu.Ingxowa yeplastiki enetyhefu inomxhuzulane omkhulu othile kwaye iya kutshona.
(4) Ukubona umlilo
Iiplastiki ze-polyethylene ezingenayo ityhefu ziyakwazi ukutsha, kunye namadangatye abhlowu kunye nomphezulu otyheli.Xa zivutha, zivuza njengeenyembezi zekhandlela, ivumba leparafini, kwaye zikhupha umsi omncinci.Iingxowa zeplastiki zepolyvinyl chloride ezinetyhefu azikwazi ukutsha kwaye ziya kucima ngokukhawuleza xa zisusiwe emlilweni.Ityheli kunye nomzantsi oluhlaza, inokuba nentambo xa ithambe, kwaye inevumba elibukhali le-hydrochloric acid.
