Izinkomishi zepulasitikiziyinto evamile ekuphileni kwethu, sivame ukusebenzisa izinkomishi zepulasitiki ukugcwalisa amanzi noma iziphuzo.Kunezinhlobo eziningi zezinkomishi zepulasitiki, ezinye izinkomishi zepulasitiki zingagcwaliswa ngamanzi ashisayo, kodwa ezinye izinkomishi zepulasitiki zingagcwaliswa ngamanzi abandayo kuphela.Ngesikhathi esifanayo, izinto ezihlukene zizophinde zihluke ngokubukeka.Impilo esisebenzisayo izinkomishi zepulasitiki ngokuvamile zenziwe nge-PP kanye ne-PET impahla, abantu abaningi bazoba phezu kwenkomishi yepulasitiki impahla ye-PP noma impahla ye-PET ilungile kule nkinga bazizwa bedidekile?Kule nkinga, okulandelayo ukwakheka okuncane ukukuphendula, abangani abanentshisekelo bazohlangana ngokushesha ukuze bakubone!
I-PP iyi-polypropylene, i-PET i-polyester.Ngokweqile, kokubili akunabuthi, kodwa mayelana nokumelana nokuguga nokumelana nesimo sezulu, i-PP ifaneleka kakhulu izinkomishi zamanzi, i-PP inokumelana nokushisa okuhle, ingakwazi ukumelana nokushisa okuphezulu kwama-degree angu-120, ukuphela kwezinto zepulasitiki ezingafakwa i-microwave.
Izicelo ze-Polypropylene (PP): izitsha ze-microwave, izimbiza, amabhakede epulasitiki, amagobolondo e-thermos, izikhwama ezilukiweyo, njll. Izici: ukuqina kwamakhemikhali aphezulu, ukusebenza kahle kwezempilo, ukumelana nokushisa okuphezulu.I-Microwave tableware ingasetshenziswa imikhiqizo yepulasitiki ye-PP ephawulwe.Ubuthi: obungenabuthi, obungenabungozi emzimbeni womuntu.I-polymer ingaba nesakhiwo esinezinhlangothi ezintathu: i-isometric, i-intergraphic, i-atactic polypropylene, ezimbili zokuqala zingacwebezela, lezi zamuva azikwazi.Imikhiqizo ye-polypropylene ethengiswayo ngokuyisisekelo iyisakhiwo semakethe ye-iso-gauge, indawo encibilikayo engu-164 ~ 170 degrees Celsius, ingxenye ecwebezelayo yokuminyana engama-0.935 grams/cubic centimeters, ingxenye engahlanzekile ye-0.851 grams/cubic centimeters.Umphumela omkhulu we-PP ukuthi kulula ukwenza i-oxidize kanye nobudala.Manje nge ukwengeza Antioxidants kanye ultraviolet absorbers ukunqoba.
Izinhlelo zokusebenza ze-polyester (PET): amabhodlela eziphuzo zepulasitiki, amabhodlela emithi, amabhodlela ezimonyo, amabhodlela kawoyela, nezinhlobonhlobo zamakepisi amabhodlela, ikhava yokufaka izinto.Izici: ukukhanya okuhle, akulula ukuphuka, ukuzinza okuhle kwamakhemikhali, okulungele ukupakishwa kwezidakamizwa okuwuketshezi noma okuqinile.Inokuvikela okuhle emisebeni ye-ultraviolet.Ubuthi: obungewona ubuthi.
Ibhodlela lepulasitiki le-PET liwumgogodla wokupakishwa kwesiphuzo.Isikhundla esivelele embonini yokupakisha isiphuzo yaseChina kufanele kube amabhodlela epulasitiki e-PET, kuze kube manje, azikho izinto zephakeji eziphakeme noma ezingcono ezitholakalayo ezithatha indawo yamabhodlela epulasitiki e-PET.Amabhodlela e-PP ngokuyinhloko ayisinyathelo esisodwa sokudonsa umjovo kanye nezinyathelo ezimbili zokushisa ezifuthayo, umshini wokubumba ekubunjweni kwamabhodlela e-PP unezinzuzo zokungafihli lutho, ukuqina, ukumelana nokushisa, futhi izindleko nazo ziphansi.
Amabhodlela epulasitiki e-PP anokumelana nokushisa okungcono, ukuvezwa komumo webhodlela kuyazwela, ukuphepha, inhlanzeko kanye nokuqukethwe kokunambitheka kokugcinwa okuphansi, intengo ishibhile kune-PET, PS, PE nezinye izinto.PP amabhodlela epulasitiki emakethe yokupakisha isiphuzo ekusetshenzisweni kwesikali bekulokhu kusondela kancane kancane kumabhodlela e-PET, ama-resin aguquliwe, izithuthukisi zokuqina, namakhono emishini nemishini ngezikhathi ezithile ukwenza ukuthuthukiswa kweziqukathi ze-PP kungathatha indawo yengilazi, iziqukathi ze-PET ne-PVC, isabelo semakethe siyakhula.
.
Izinto ze-PP ne-PET zinezinzuzo nezici zazo, akukho okuhle noma okubi ngokuphelele, ikakhulukazi kuncike ezidingweni zomuntu ngamunye kanye nokusetshenziswa kwesimo sokunquma, uma kuvame ukusetshenziswa emazingeni okushisa aphezulu, ungakhetha impahla ye-PP.Okungenhla ukuhlaziya kwe-PPizinkomishi zepulasitikikanye nezinkomishi zepulasitiki ze-PET, ngethemba ukuthi zingakusiza.
