Lisosa tsa Brittleness ho PET Sheets
Lisosa tsa brittleness maqepheng a PET li rarahane 'me li ka hlahisoa ke lintlha tse' maloa tsa bohlokoa:
1. Kalafo ea Mocheso o Feteletseng Nakong ea tlhahiso ea maqephe a PET, phekolo ea mocheso e hlokahalang. Leha ho le joalo, haeba phekolo ea mocheso e le ngata haholo, e ka lebisa ho tekanyo e feteletseng ea crystallization, e leng se etsang hore lakane e be brittle 'me e khone ho senya.
2. Ho senyeha ha Li-additive Li-additives tse fapa-fapaneng tse kang li-plasticizers, stabilizers, le li-masterbatches tsa mebala li kenyelelitsoe maqepheng a PET. Ho senyeha ha li-additives tsena ho ka lebisa ho lahleheloa ke boima ba pele ba lakane, ho etsa hore e be bobebe haholoanyane. Ho feta moo, lintlha tse joalo ka tšebeliso e feteletseng, tšebeliso e tlase, kapa tatellano e fosahetseng ea li-additives le tsona li ka ama boleng ba maqephe a PET.
3. Maemo a sa nepahalang a polokelo Sebaka sa polokelo se ama haholo boleng ba maqephe a PET. Haeba a bolokoa maemong a nang le mocheso o phahameng kapa mongobo, maqephe a PET a ka 'na a ba le oxidation kapa karabelo ea ho bola, e lebisang ho brittleness.
4. Mathata a Ts'ebetso ea Tlhahiso Ho sebetsana ka tsela e fosahetseng nakong ea tlhahiso ea lihlahisoa ho ka boela ha ama boleng ba maqephe a PET. Lintho tse kang ts'ebetso ea extrusion, taolo ea ho pholisa, le phetoho ea khatello e ka fetola sebopeho sa ka hare sa lakane, e leng se bakang tahlehelo ea thepa ea mochine le ho eketseha ha brittleness.
Mehato ea Thibelo ea PET Sheet Brittleness
Ho thibela brittleness ho maqephe a PET, mehato e mengata e ka nkuoa:
1. Laola Phekolo ea Mocheso Mocheso Nakong ea tlhahiso, ke habohlokoa ho laola ka hloko mocheso oa phekolo ea mocheso le nako ea nako ho qoba crystallization e feteletseng, e ka lebisang ho brittleness.
2. Keketso e Loketseng ea Li-Additives Additives e phetha karolo ea bohlokoa boleng ba maqephe a PET. Ho bohlokoa ho khetha le ho li eketsa ka nepo ho latela litlhoko tsa 'nete. Ho feta moo, tlhahlobo e tloaelehileng e lokela ho etsoa ho lekola boleng ba li-additives ho qoba ho senyeha ho ka amang ho tiea ha leqephe.
3. Maemo a ho Laola Maemo a PET Lipampiri tsa PET li lokela ho bolokoa libakeng tse omeletseng, tse nang le moea o motle, le tse thibelang mongobo, ho qoba ho pepesehela mocheso o phahameng le mongobo. Bakeng sa maqephe a bolokiloeng ka nako e telele, mekhoa ea ho omisa e ka sebelisoa ho fokotsa mongobo.
4. Etsa bonnete ba Mekhoa e Loketseng ea Tlhahiso Nakong ea tlhahiso, basebetsi ba tlameha ho latela mekhoa e nepahetseng ea ho thibela litaba tse bakoang ke ts'ebetso ea extrusion, taolo ea ho pholile, kapa khatello ea khatello e ka amang sebopeho sa ka hare le ts'ebetso ea mechine ea maqephe a PET.
5. Lipampiri tsa PET ke lisebelisoa tsa ho paka tse sebetsang hantle, empa brittleness ke taba e tloaelehileng lits'ebetsong tse sebetsang. Ho qoba brittleness, tlhokomelo e hlokolosi e tlameha ho lefshoa taolong ea tlhahiso le lisebelisoa tsa ts'ebeliso, joalo ka kalafo ea mocheso, khetho ea tlatsetso le litekanyetso, le maemo a polokelo. Ka ho laola lintlha tsena ka thata, hoa khoneha ho hlahisa maqephe a PET ka ts'ebetso e tsitsitseng.
