Umehluko phakathi kwezithako zemikhiqizo ye-CPLA kanye ne-PLA. Ngokuthuthuka kokuqwashisa ngemvelo, isidingo sezinto zokusetshenziswa ezibolayo siyakhula. Uma kuqhathaniswa nezinto zokusetshenziswa zepulasitiki zendabuko, izinto zokusetshenziswa ze-CPLA kanye ne-PLA sezibe imikhiqizo ethandwa kakhulu enobungani nemvelo emakethe ngenxa yazo.iyabola futhi ikwazi ukubolaizakhiwo. Ngakho-ke, uyini umehluko phakathi kwezithako ze-CPLA kanye ne-PLA tableware? Ake senze isingeniso sesayensi esidumile ngezansi.
Okokuqala, ake sibheke izithako ze-CPLA. Igama eliphelele le-CPLA yi-Crystallized Poly Lactic Acid. Liyizinto ezixutshwe ne-polylactic acid (i-Poly Lactic Acid, ebizwa ngokuthi i-PLA) kanye nama-reinforcement agents (njengezigcwalisi zamaminerali). I-PLA, njengesithako esiyinhloko, ivame kakhulu phakathi kwezinto ezinobungani nemvelo. Ikhiqizwa ngokubilisa isitashi ezitshalweni ezivuselelekayo njenge-cornstarch noma umoba. Izitsha ze-PLA zenziwe ngezinto ezihlanzekile ze-PLA. Izitsha ze-PLA zibola ngokwemvelo futhi ziyinto enobungani nemvelo kakhulu. Njengoba umthombo we-PLA ugxile kakhulu ezintweni zokusetshenziswa zezitshalo, ngeke ubangele ukungcola emvelweni lapho ubola endaweni yemvelo.
Okwesibili, ake sibheke ukubola kwezithako ze-CPLA kanye ne-PLA. Zombili izitsha ze-CPLA kanye ne-PLA ziyizinto ezibolayo, futhi zingabola endaweni efanele. Kodwa-ke, ngenxa yokuthi ezinye izinto zokuqinisa zengezwa ezintweni ze-CPLA ukuze zenze zibe kristalu kakhulu, izitsha ze-CPLA zithatha isikhathi eside ukubola. Ngakolunye uhlangothi, izitsha ze-PLA zibola ngokushesha, futhi ngokuvamile kuthatha izinyanga eziningana kuya eminyakeni eminingana ukubola ngokuphelele.
Okwesithathu, ake sixoxe ngomehluko phakathi kwezitsha zokudla ze-CPLA neze-PLA maqondana nokuvundisa. Ngenxa yokubola kwemvelo kwezinto ze-PLA, zingavundiswa ngaphansi kwezimo ezifanele zokuvundisa futhi ekugcineni zibole zibe umanyolo kanye nokulungiswa kwenhlabathi, zinikeze izakhamzimba ezengeziwe emvelweni. Ngenxa yokuqina kwayo okuphezulu, izitsha zokudla ze-CPLA ziwohloka kancane kancane, ngakho-ke kungathatha isikhathi eside enkambisweni yokwenza umquba.
Okwesine, ake sibheke ukusebenza kwemvelo kwezitsha zokudla ze-CPLA kanye ne-PLA. Kungakhathaliseki ukuthi yi-CPLA nomaIzitsha zokudla ze-PLA, zingashintsha ngempumelelo izitsha zepulasitiki zendabuko, ngaleyo ndlela zinciphise ukungcoliswa kwemvelo. Ngenxa yezakhiwo zazo ezibolayo, ukusebenzisa izitsha ze-CPLA kanye ne-PLA kunganciphisa ukukhiqizwa kwemfucuza yepulasitiki futhi kunciphise umonakalo endaweni yemvelo. Ngaphezu kwalokho, ngoba i-CPLA kanye ne-PLA zenziwe ngezitshalo ezivuselelekayo, inqubo yazo yokukhiqiza inobungani nemvelo.
Okwesihlanu, sidinga ukuqonda ukuthi ngabe kukhona yini umehluko ekusetshenzisweni kwezitsha zetafula ze-CPLA ne-PLA. Izitsha zetafula ze-CPLA zimelana nokushisa okuphezulu kanye namafutha. Lokhu kungenxa yokwengezwa kwezinye izinto zokuqinisa lapho kwenziwa izitsha zetafula ze-CPLA, okwandisa ubukhristali bezinto ezibonakalayo. Uma usebenzisa izitsha zetafula ze-PLA, udinga ukunaka ukuze ugweme imiphumela yokushisa okuphezulu, amafutha nezinye izinto. Ngaphezu kwalokho, ngoba izitsha zetafula ze-CPLA zenziwa ngokucindezela okushisa okuphezulu, ukuma kwazo kuzinzile futhi akulula ukukuguquguqula. Izitsha zetafula ze-PLA ngokuvamile zisebenzisa ubuchwepheshe bokubumba umjovo, obungakhiqiza izitsha nezitsha zetafula ezinezimo ezahlukahlukene.
Okokugcina, ake sifingqe umehluko phakathi kwezithako ze-CPLA kanye ne-PLA tableware. I-CPLA tableware iyinto ekristalu kakhulu exutshwe ne-polylactic acid kanye nama-reinforcement agents. Inokumelana okuhle nokushisa okuphezulu kanye nokumelana namafutha. I-PLA tableware yenziwe ngezinto ze-PLA ezimsulwa, ezibola ngokushesha futhi kulula ukuzenza umquba. Kodwa-ke, kufanele kuqashelwe ukugwema ukuzisebenzisa ngaphansi kwezimo zokushisa okuphezulu kanye nokugcoba. Kungakhathaliseki ukuthi yi-CPLA noma i-PLA tableware, zombili ziyabola futhiimikhiqizo enobungani nemvelo ekwazi ukufuthwa, okunganciphisa ngempumelelo ukungcola kwemvelo okubangelwa udoti wepulasitiki.
Sithemba ukuthi ngesingeniso sesayensi esidumile esingenhla, ungawuqonda kangcono umehluko phakathi kwezithako zemikhiqizo ye-CPLA kanye ne-PLA tableware. Khetha i-MVI ECOPACK tableware enobungani nemvelo bese wenza indima yakho ekuvikeleni imvelo.
