Iikomityi zeplastikizizinto eziqhelekileyo ebomini bethu, sihlala sisebenzisa iikomityi zeplastiki ukugcwalisa amanzi okanye iziselo.Zininzi iindidi zeekomityi zeplastiki, ezinye iikomityi zeplastiki zinokuzaliswa ngamanzi ashushu, kodwa ezinye iikomityi zeplastiki zinokuzaliswa kuphela ngamanzi abandayo.Ngexesha elifanayo, izinto ezahlukeneyo ziya kuba zihluke kwimbonakalo.Ubomi esibusebenzisa iikomityi zeplastiki ziqhele ukwenziwa ngezinto zePP kunye ne-PET, abantu abaninzi baya kuba kwindebe yeplastiki yinto yePP okanye imathiriyeli ye-PET ilungile kule ngxaki uzive udidekile?Kule ngxaki, ezi zilandelayo zincinci zizenzele ukuphendula kuwe, abahlobo abanomdla baya kuhlangana ngokukhawuleza ukuze babone!
I-PP yi-polypropylene, i-PET yi-polyester.Ngokwethiyori zombini ayinayo ityhefu, kodwa ngokokumelana nokuguga kunye nokumelana nemozulu, iPP ifaneleke ngakumbi kwiikomityi zamanzi, iPP inokumelana nobushushu obulungileyo, inokumelana nobushushu obuphezulu be-120 degrees, yeyona nto kuphela yeplastiki enokufakwa kwi. i-microwave.
Izicelo zePolypropylene (PP): izitya ze-microwave, iimbiza, iibhakethi zeplastiki, iigobolondo ze-thermos, iingxowa ezilukiweyo, njl. njl.I-Microwave tableware ingasetyenziswa ephawulwe iimveliso zeplastiki zePP.Ubuthi: ayinayo ityhefu, ayinabungozi emzimbeni womntu.Ipolymer inokuba nesakhiwo sesithathu-ntathu: isometric, i-intergraphic, i-atactic polypropylene, ezimbini zokuqala ziyakwazi ukucwebezela, le yokugqibela ayikwazi.Iimveliso zepolypropylene ezifumaneka ngokurhweba zisisiseko se-iso-gauge yemarike, indawo yokunyibilika ye-164 ~ 170 degrees Celsius, inxalenye yecrystalline yoxinano lwe-0.935 grams / cubic centimeters, inxalenye engacocekanga ye-0.851 grams / cubic centimeters.Eyona nto itsalayo yePP kukuba kulula ukwenza i-oxidize kunye nobudala.Ngoku kunye nokongezwa kwe-antioxidants kunye ne-absorbents ye-ultraviolet ukoyisa.
Usetyenziso lwePolyester (PET): iibhotile zesiselo zeplastiki, iibhotile zamayeza, iibhotile zokuthambisa, iibhotile zeoyile, kunye neendidi ngeendidi zeebhotile, isigqubuthelo sokugquma.Iimpawu: ukungafihli kakuhle, akukho lula ukwaphula, uzinzo lwekhemikhali elungileyo, lulungele ukupakishwa kweziyobisi ezilulwelo okanye eziqinileyo.Inokukhusela okulungileyo kwimitha ye-ultraviolet.Ubuthi: ayinayo ityhefu.
Ibhotile yeplastiki ye-PET yeyona nto iphambili yokupakishwa kwesiselo.Isikhundla esiphezulu kwishishini lokupakisha isiselo saseTshayina kufuneka libe ziibhotile zeplastiki ze-PET, ukuza kuthi ga ngoku, akukho zipakethe ziphezulu okanye zingcono zifunyenwe zithatha indawo yeebhotile zeplastiki ze-PET. Umatshini wokubumba ekubunjweni kweebhotile ze-PP unezibonelelo zokungafihli, zomelele, zimelana nobushushu, kwaye iindleko nazo ziphantsi.
Iibhotile zeplastiki ze-PP ezinokumelana nobushushu obungcono, umfanekiso webhotile ubuthathaka, ukhuseleko, ucoceko kunye nemixholo yencasa yokugcinwa komgangatho ophantsi, ixabiso lixabiso eliphantsi kunePET, PS, PE kunye nezinye izinto.PP iibhotile zeplastiki kwintengiso yesiselo. Ekusetyenzisweni kwesikali kuye kwasondela ngokuthe ngcembe kwiibhotile ze-PET, ii-resin ezilungisiweyo, izixhasi zokungena, kunye nezakhono zoomatshini kunye nezixhobo amaxesha ngamaxesha ukwenza uphuhliso lwezikhongozeli zePP zinokuthatha indawo yeglasi, izikhongozeli zePET kunye nePVC, isabelo sentengiso siyakhula.
.
Izinto ze-PP kunye ne-PET zineenzuzo kunye neempawu zazo, akukho nto ilungileyo okanye imbi, ngokukodwa kuxhomekeke kwiimfuno zomntu ngamnye kunye nokusetyenziswa kwemeko yokugqiba, ukuba isetyenziswa rhoqo kumaqondo aphezulu, unokukhetha izinto zePP.Oku ngasentla kuhlalutyo lwePPiikomityi zeplastikikunye neekomityi zeplastiki zePET, ndiyathemba ukuba zinokukunceda.
