Ho kenyelletsoa ha polyamid pa6
Polyamide, e bitsoang polyamide pa ka bokhuts'oane, hangata e tsejoa e le nylon.Ke mofuta oa polasetiki ea crystalline thermoplastic e entsoeng ke polymerization ea binary amines le diacid kapa lactam.Ho na le mefuta e mengata ea PA, ho latela palo ea liathomo tsa khabone ho monoma e amehang karabelong ea polymerization, mme mefuta e fapaneng ea PA e nang le ts'ebetso e fapaneng e ka etsoa, joalo ka PA6, PA66, PA612, PA1010, PA11, PA12, PA46 , PA9, PA1212, joalo-joalo PA6 le PA66 li sebelisoa haholo, li nka karolo ea 90% ea kakaretso ea tlhahiso.
Thepa e akaretsang ea polyamid pa6
Polyamid pa6 e na le polarity, e se nang chefo, ha e latsoehe ebile ho bonolo ho e mebala; Mofuta oa kristale (50 ho isa ho 60%), granule e tšoeu ea lebese kapa e mosehla o khanyang; Mekelikeli ea Newtonian (maro a Newtonian a bolela maro moo khatello ea maikutlo e lekantsoeng teng. Sekhahla sa khatello); Boima ba metsi: 1.02 ho isa ho 1.20g/cm³; ho monya metsi a phahameng, karabelo ea hydrolysis e tla etsahala ka likhato tse 230 tsa Celsius; ho monya metsi PA46 > PA6 > PA66 > PA1010 > PA11 > PA12 > PA1212;Sekhahla se seholo sa ho honyela ha ho bopeha.PP, PE > PA > PS, ABS.Thepa e bohareng ea mokoallo le mokoallo o matla moeeng.
Thepa ea mochini ea polyamid pa6
Thepa ea mochini ea polyamid pa6 ka kakaretso e amana le crystallinity: Ha kristale e phahame, e phahamisa matla le ho tiea ho matla.Mabapi le matla, PC> PA66> PA6> POM> ABS.Matla a ameha haholo ke hygroscopicity, mocheso o phahameng, o phahameng oa hygroscopicity, o theola matla a matla le thepa e meng.
Tšusumetso e matla e ameha haholo ke ts'ebetso ea hygroscopic.Ka ho eketseha ha mocheso, ho monya metsi hoa eketseha, 'me boima bo eketseha.(Hangata, boima bo fokola sebakeng se omileng le mocheso o tlase, 'me ho ka etsahala hore ho be le khatello ea maikutlo ka lihlahisoa tsa tšepe le ho robeha ha brittle ho 0 ℃.
Polyamid pa6 e na le boits'oaro bo botle ba boithati le boits'oaro bo botle ba ho sesa.
Ho hanyetsa ka ho fetisisa ho oli, mohlala.peterole.
Matla a mokhathala a phahame, ka kakaretso ke 20% ho isa ho 30% ea matla a ho tsitsa.Matla a mokhathala a PA6 le PA66 a ka fihla hoo e ka bang 22MPa, ea bobeli ho POM (35MPa) le ho feta PC (10-14MPa).Tatelano mabapi le matla a mokhathala: POM > PBT, PET > PA66 > PA6 > PC > PSF > PP.
Boima bo phahameng, PA66: 108 ho 120HRR;Setšoantšo sa PA6120HRR
Khanyetso e mpe ea Creep: E betere ho feta PP le PE, hape e mpe ho feta ABS le POM.
Khanyetso e mpe ea khatello ea maikutlo: Phekolo ea ho kopanya kapa ea mongobo e lokela ho etsoa kamora ho sebetsa lihlahisoa.
