Isahluko 3: Ukusebenza Nokubukeka - Ukubhekana Nezidingo Eziyinhloko ze-PPF

Kwimikhiqizo ye-PPF eqediwe ngokuphelele, ukusebenza kahle kokukhanya kanye nokubukeka okuhlanzekile “amakhadi okubiza” abonakalayo, kuyilapho ukuzinza ngokomzimba namakhemikhali okuvamile kwakha “umgogodla” ongabonakali.

1. Ukuvikela Ukusebenza Kokukhanya: Ukuphuzi kanye Nomhwamuko

• Imbangela Yomsuka: Ngaphandle kwesigaba sokumelana kwe-UV sezinto zokusetshenziswa, ukushiswa kwe-thermal ngesikhathi sokucubungula kuyimbangela eyinhloko yokwanda kokuphuzi kokuqala kanye nomswakama. Amazinga okushisa aphezulu kakhulu okucubungula noma isikhathi eside sokuhlala kokuncibilika kungabangela ukuqhekeka kweketanga kanye nokushiswa kwe-oxidation kuma-molecule e-TPU e-aliphatic.
• Isu Lenqubo LikaLinghua: Sisungule isizindalwazi "Sokushisa Okusebenzayo Okuncane Kokucubungula", sibeka ijika lephrofayili yokushisa eliyingqayizivele nelifanele kakhulu lebanga ngalinye lezinto zokusetshenziswa. Ngaphezu kwalokho, ukwengeza iphampu yegiya lokuncibilika phakathi kwe-extruder kanye ne-die kunciphisa ukuncika kwengcindezi, okuvumela ukuphuma okuzinzile emazingeni okushisa okuncibilika aphansi, athambile, ngaleyo ndlela silondoloze kakhulu izakhiwo zokukhanya zezinto zokusetshenziswa.

2. Ukugwema Amaphutha Okusebenza: Ukwehlukanisa, Iphunga, kanye Nokuncipha

• Ukuhlukanisa (Ukuqhekeka Kwezingqimba Eziphakathi): Ngokuvamile kuvela ekuncibilikeni okungekuhle kwepulasitiki ngesikhathi sokukhipha noma ukuhambisana okungekuhle phakathi kwezingqimba zezinto ezahlukene (isb., izingqimba ezisebenzayo ezihlanganisiwe). Sithuthukisa ukuhambisana kwenkomba yokugeleza kokuncibilika kwezinto zengqimba ngayinye ku-co-extruder futhi sithuthukise ukwakheka kwe-feedblock/manifold die, siqinisekisa ukuhlangana kwezinga lama-molecule kanye nokubopha okuqinile phakathi kwezingqimba esimweni esiqinile kakhulu.
• Iphunga Elingathandeki: Ngokuyinhloko livela ekufudukeni kokushisa noma ukubola kwezithasiselo zama-molecule amancane (isb. ama-plasticizer, ama-antioxidants) ezintweni zokusetshenziswa, kanye nama-monomers asele angase alandele ku-TPU uqobo. Sikhetha izithasiselo zokudla ezihlanzekile kakhulu, ezinesisindo sama-molecule aphezulu. Ngaphezu kwalokho, kufakwa igumbi lokususa igesi eliku-inthanethi ekugcineni komugqa wokukhipha ukuze kususwe ama-organic compounds (ama-VOC) avela efilimini ngaphambi kokuba aphole futhi aqine ngokugcwele.
• Ukuncipha Okukhulu Kokushisa: Kuthinta ukumbozwa okulandelayo kanye nokuqina kobukhulu bokufakwa. Sisebenzisa iyunithi yokwelapha ukushisa ye-infrared eku-inthanethi ukuze kubekwe ukushisa kwesibili okunembile kwefilimu eyakhiwe, kukhishwe ukucindezeleka kokuma kanye nokuzinzisa ukuncipha kokushisa kwe-longitudinal/transverse ezingeni elihamba phambili embonini elingu-<1%.
