Izinkomishi zepulasitikikuyinto evamile empilweni yethu, 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 ezahlukene nazo zizohluka ngokubukeka. Impilo esiyisebenzisayo izinkomishi zepulasitiki zivame ukwenziwa ngezinto ze-PP ne-PET, abantu abaningi bazobe besenkomishini yepulasitiki ingabe izinto ze-PP noma izinto ze-PET zilungile kule nkinga uzizwa udidekile? Ngale nkinga, izimonyo ezincane ezilandelayo ukuze zikuphendule, abangani abanentshisekelo bazohlangana ngokushesha ukuze bazibone!
I-PP iyi-polypropylene, i-PET iyi-polyester. Ngokwethiyori zombili azinabo ubuthi, kodwa maqondana nokumelana nokuguga kanye nokumelana nesimo sezulu, i-PP ifaneleka kakhulu ezinkomishini zamanzi, i-PP inokumelana okuhle nokushisa, ingamelana namazinga okushisa aphezulu angama-degrees angu-120, iyona kuphela impahla yepulasitiki engafakwa kwi-microwave.
Ukusetshenziswa kwe-polypropylene (PP): izitsha ze-microwave, amabhodwe, amabhakede epulasitiki, amagobolondo e-thermos, izikhwama ezilukiwe, njll. Izici: ukuzinza okuphezulu kwamakhemikhali, ukusebenza kahle kwempilo, ukumelana nokushisa okuphezulu. Izitsha ze-microwave zingasetshenziswa imikhiqizo yepulasitiki ye-PP ephawulwe. Ubuthi: abunabo ubuthi, abunangozi emzimbeni womuntu. I-polymer ingaba nesakhiwo esinezinhlangothi ezintathu: i-isometric, i-intergraphic, i-atactic polypropylene, ezimbili zokuqala zingakhazimula, ezokugcina azikwazi. Imikhiqizo ye-polypropylene etholakala kwezentengiselwano ngokuyisisekelo iyisakhiwo semakethe se-iso-gauge, iphuzu lokuncibilika elingu-164 ~ 170 degrees Celsius, ingxenye yekristalu yobuningi obungu-0.935 grams / cubic centimeters, ingxenye engahlanzekile engamagremu angu-0.851 / cubic centimeters. Inkinga enkulu ye-PP ukuthi kulula ukuyixuba futhi iguge. Manje ngokungezwa kwama-antioxidants kanye nama-ultraviolet absorbers ukuze kunqotshwe.
Ukusetshenziswa kwe-polyester (PET): amabhodlela eziphuzo epulasitiki, amabhodlela emithi, amabhodlela ezimonyo, amabhodlela kawoyela, kanye nezinhlobonhlobo zezivalo zamabhodlela, isembozo sokushisa. Izici: ukucaca okuhle, akulula ukuphula, ukuzinza okuhle kwamakhemikhali, okufanelekela ukupakishwa okuhlukahlukene koketshezi noma okuqinile kwemithi. Inezivikelo ezinhle zemisebe ye-ultraviolet. Ubuthi: abunabo ubuthi.
Ibhodlela lepulasitiki le-PET liyindlela eyinhloko yokupakisha iziphuzo. Isikhundla esivelele embonini yokupakisha iziphuzo yaseShayina kufanele sibe amabhodlela epulasitiki e-PET, kuze kube manje, azikho izinto zokupakisha ezingcono noma ezingcono ezitholakalayo zokufaka esikhundleni samabhodlela epulasitiki e-PET. Amabhodlela e-PP ikakhulukazi asebenza ngokucindezela okukodwa kanye nokucindezela kokudonsa okufudumeza okunezinyathelo ezimbili, umshini wokubumba ekubunjweni kwamabhodlela e-PP unezinzuzo zokucaca, ukuqina, ukumelana nokushisa, futhi izindleko nazo ziphansi.
Amabhodlela epulasitiki e-PP anokumelana nokushisa okungcono, ukubonakaliswa kwesimo sebhodlela okubucayi, ukuphepha, inhlanzeko kanye nokuqukethwe kokunambitheka kokugcinwa kokungabi nalutho, intengo ishibhile kune-PET, PS, PE nezinye izinto. Amabhodlela epulasitiki e-PP emakethe yokupakisha iziphuzo ekusetshenzisweni kwesikali abelokhu esondela kancane kancane emabhodleleni e-PET, ama-resin aguquliwe, izithuthukisi zokungena, kanye namakhono emishini nemishini ngezikhathi ezithile ukwenza ukuthuthukiswa kwezitsha ze-PP kungathatha indawo yezitsha zengilazi, i-PET kanye ne-PVC, isabelo semakethe siyakhula.
.
Izinto ze-PP ne-PET zinezinzuzo kanye nezici zazo, akukho okuhle noma okubi ngokuphelele, ikakhulukazi kuncike ezidingweni zomuntu ngamunye kanye nokusetshenziswa kwesimo ukunquma, uma kuvame ukusetshenziswa emazingeni okushisa aphezulu, ungakhetha izinto ze-PP. Okungenhla ukuhlaziywa kwe-PPizinkomishi zepulasitikikanye nezinkomishi zepulasitiki ze-PET, ngithemba ukuthi zingakusiza.
