Ezimpilweni zethu zansuku zonke, amabhodlela epulasitiki angabonakala yonke indawo.Kazi ubonile yini ukuthi kunophawu lwezinombolo olumise okonxantathu ngaphansi kwamabhodlela epulasitiki amaningi (izinkomishi).
Ngokwesibonelo:
amabhodlela amanzi amaminerali, amakwe 1 phansi;
Izinkomishi zepulasitiki ezikwazi ukumelana nokushisa zokwenza itiye, eziphawulwe ngo-5 phansi;
Izitsha zama-noodle asheshayo namabhokisi okudla okusheshayo, phansi kubonisa u-6;
…
Njengoba wonke umuntu azi, amalebula angaphansi kwala mabhodlela epulasitiki anezincazelo ezijulile, aqukethe "ikhodi yobuthi" yamabhodlela epulasitiki futhi amele ububanzi bokusetshenziswa kwemikhiqizo yepulasitiki ehambisanayo.
“Izinombolo namakhodi angaphansi kwebhodlela” ayingxenye yokuhlonza umkhiqizo wepulasitiki oshiwo kumazinga kazwelonke:
Uphawu lukanxantathu olugaywa kabusha ngaphansi kwebhodlela lepulasitiki lubonisa ukugaywa kabusha, futhi izinombolo 1-7 zibonisa uhlobo lwe-resin esetshenziswa epulasitiki, okwenza kube lula futhi kulula ukuhlonza izinto zepulasitiki ezivamile.
"1" PET - i-polyethylene terephthalate
Ingabe inkomishi yepulasitiki oyiphuzayo inobuthi?Vele ubheke izinombolo ezingezansi futhi uthole!
Le nto ayizwani nokushisa kufika ku-70°C futhi ifaneleka kuphela ukubamba iziphuzo ezifudumele noma eziqandisiwe.Ikhubazeka kalula uma igcwele uketshezi olushisa kakhulu noma ifudunyezwa, futhi izinto eziyingozi emzimbeni womuntu zingase zincibilike;ngokuvamile amabhodlela amanzi amaminerali kanye amabhodlela isiphuzo carbonated enziwe ngale nto.
Ngakho-ke, ngokuvamile kunconywa ukuthi ulahle amabhodlela eziphuzo ngemva kokusetshenziswa, ungawasebenzisi kabusha, noma uwasebenzise njengezitsha zokugcina ukuze ubambe ezinye izinto.
“2″ HDPE – high density polyethylene
Ingabe inkomishi yepulasitiki oyiphuzayo inobuthi?Vele ubheke izinombolo ezingezansi futhi uthole!
Le nto ingamelana namazinga okushisa aphezulu angu-110°C futhi ivame ukusetshenziselwa ukwenza amabhodlela emithi emhlophe, izinto zokuhlanza, neziqukathi zepulasitiki zemikhiqizo yokugeza.Iningi lezikhwama zepulasitiki ezisetshenziswa njengamanje ezitolo ezinkulu ukubamba ukudla nazo zenziwe ngale nto.
Lolu hlobo lwesiqukathi akulula ukusihlanza.Uma ukuhlanzwa kungaphelele, izinto zokuqala zizohlala futhi akunconywa ukuthi zigaywe kabusha.
"3" i-PVC - i-polyvinyl chloride
Ingabe inkomishi yepulasitiki oyiphuzayo inobuthi?Vele ubheke izinombolo ezingezansi futhi uthole!
Le nto ingamelana namazinga okushisa aphezulu angu-81°C, inepulasitiki elihle kakhulu, futhi ishibhile.Kulula ukukhiqiza izinto eziyingozi emazingeni okushisa aphezulu futhi zikhishwa ngisho nangesikhathi sokukhiqiza.Lapho izinto ezinobuthi zingena emzimbeni womuntu nokudla, zingase zidale umdlavuza webele, ukukhubazeka kokuzalwa ezinganeni ezisanda kuzalwa nezinye izifo..
Njengamanje, le nto isetshenziswa kakhulu kuma-raincoat, izinto zokwakha, amafilimu epulasitiki, amabhokisi epulasitiki, njll., futhi akuvamile ukusetshenziselwa ukupakisha ukudla.Uma isetshenzisiwe, qiniseka ukuthi ungayivumeli ukuthi ifudumale.
“4″ LDPE – i-polyethylene enezinga eliphansi
Ingabe inkomishi yepulasitiki oyiphuzayo inobuthi?Vele ubheke izinombolo ezingezansi futhi uthole!
Lolu hlobo lwezinto alunakho ukumelana nokushisa okuqinile futhi lusetshenziswa kakhulu ekukhiqizeni ifilimu yokudla nefilimu yepulasitiki.
Ngokuvamile, ifilimu yokunamathela ye-PE efanelekayo izoncibilika lapho izinga lokushisa lidlula i-110 ° C, ishiya amanye amalungiselelo epulasitiki angakwazi ukubola umzimba womuntu.Ngaphezu kwalokho, lapho ukudla kugoqwe ngefilimu yokudla futhi kushisa, amafutha ekudleni azoncibilika kalula efilimu yokudla.izinto eziyingozi ziyancibilika.
Ngakho-ke, kunconywa ukuthi ukudla okusongwe ngepulasitiki kufanele kususwe ngaphambi kokukufaka kuhhavini ye-microwave.
“5″ PP – polypropylene
Ingabe inkomishi yepulasitiki oyiphuzayo inobuthi?Vele ubheke izinombolo ezingezansi futhi uthole!
Le nto, evame ukusetshenziselwa ukwenza amabhokisi esidlo sasemini, ingamelana namazinga okushisa aphezulu angu-130°C futhi inokungafihli lutho.Iwukuphela kwebhokisi lepulasitiki elingafakwa kuhhavini we-microwave futhi lingasetshenziswa kabusha ngemva kokuhlanza ngokuphelele.
Kodwa-ke, kufanele kuqashelwe ukuthi amabhokisi athile esidlo sasemini anophawu oluthi “5″ ngaphansi, kodwa anophawu oluthi “6” esivalweni.Kulesi simo, kunconywa ukuthi isivalo sisuswe lapho ibhokisi lesidlo sasemini lifakwa kuhhavini ye-microwave, hhayi kanye nomzimba webhokisi.Beka ku-microwave.
“6″ PS——I-Polystyrene
Ingabe inkomishi yepulasitiki oyiphuzayo inobuthi?Vele ubheke izinombolo ezingezansi futhi uthole!
Lolu hlobo lwezinto ezibonakalayo lungakwazi ukumelana nokushisa kwama-70-90 degrees futhi lunokucaca okuhle, kodwa alukwazi ukufakwa kuhhavini ye-microwave ukuze kugwenywe ukukhululwa kwamakhemikhali ngenxa yokushisa ngokweqile;nokubamba iziphuzo ezishisayo kuzokhiqiza ubuthi futhi kukhulule i-styrene lapho ishisiwe.Ivamise ukusetshenziswa ekukhiqizeni Okubalulekile kwamabhokisi e-noodle ohlobo lwesitsha kanye namabhokisi okudla okusheshayo anegwebu.
Ngakho-ke, kunconywa ukugwema ukusebenzisa amabhokisi okudla okusheshayo ukupakisha ukudla okushisayo, noma ukuwasebenzisa ukubamba ama-acids aqinile (njengejusi lewolintshi) noma izinto ezinamandla ze-alkaline, ngoba zizobola i-polystyrene engalungile emzimbeni womuntu futhi ingakwazi ukubola. dala umdlavuza kalula.
"7"Abanye - I-PC namanye amakhodi epulasitiki
Ingabe inkomishi yepulasitiki oyiphuzayo inobuthi?Vele ubheke izinombolo ezingezansi futhi uthole!
Lena impahla esetshenziswa kakhulu, ikakhulukazi ekwenzeni amabhodlela ezingane, izinkomishi zasemkhathini, njll. Nokho, bekulokhu kuyimpikiswano eminyakeni yamuva nje ngoba iqukethe i-bisphenol A;ngakho-ke, qaphela futhi unake ngokukhethekile lapho usebenzisa lesi sitsha sepulasitiki.
Ngakho-ke, ngemva kokuqonda izincazelo ezifanele zalawa malebula epulasitiki, indlela yokuqhekeka "ikhodi yobuthi" yamapulasitiki?
Izindlela ezi-4 zokubona ubuthi
(1) Ukuhlolwa kwezinzwa
Izikhwama zepulasitiki ezingenabo ubuthi zimhlophe qhwa, ziyashintshashintsha, noma azinambala futhi zisobala, ziyagobeka, zibushelelezi lapho uzithinta, futhi zibonakala zinengcina ngaphezulu;izikhwama zepulasitiki ezinobuthi zinemfucumfucu noma ziphuzi ngokukhanyayo ngombala futhi zizwakala zinamathela.
(2) Ukutholwa kwe-Jitter
Thatha ingxenye eyodwa yesikhwama sepulasitiki bese usinyakazisa ngamandla.Uma ikhipha umsindo ohlabayo, ayinabo ubuthi;uma ikhipha umsindo ongacacile, iwushevu.
(3) Ukuhlolwa kwamanzi
Beka isikhwama sepulasitiki emanzini bese usicindezela phansi.Isikhwama sepulasitiki esingenabo ubuthi sinamandla adonsela phansi amancane athile futhi singantanta phezulu.Isikhwama sepulasitiki esinobuthi sinamandla adonsela phansi amakhulu futhi sizocwila.
(4) Ukutholwa komlilo
Izikhwama zepulasitiki ze-polyethylene ezingenabuthi ziyavutha, ezinamalangabi aluhlaza okwesibhakabhaka neziqongo eziphuzi.Lapho zivutha, ziconsa njengezinyembezi zekhandlela, iphunga likapharafini, futhi zikhipha intuthu encane.Izikhwama zepulasitiki ze-polyvinyl chloride ezinobuthi azivuthi futhi zizocisha ngokushesha nje lapho zikhishwa emlilweni.Iphuzi ngephansi eliluhlaza, ingaba yizintambo uma ithambe, futhi inephunga elimnandi le-hydrochloric acid.
