Nzira yekuziva sei uye kusarudza pakati peyakagadziridzwa PA6 nePA66 (Chikamu 1)?

Nekukura kuri kuwedzera kweakagadziridzwa naironi R&D tekinoroji, chiyero chekushandisa chePA6 nePA66 chakawedzera zvishoma nezvishoma. Vazhinji vagadziri vezvigadzirwa zvepurasitiki kana vashandisi venaironi zvigadzirwa zvepurasitiki hazvisi pachena nezve mutsauko uripo pakati pePA6 nePA66. Pamusoro pezvo, sezvo pasina pachena misiyano yekuona pakati pePA6 nePA66, izvi zvakonzera kuvhiringika kwakawanda. PA6 nePA66 zvingasiyaniswe sei, uye zvinofanirwa kusarudzwa sei?

Kutanga, Mazano eKuziva PA6 uye PA66:
Kana zvapiswa, zvese PA6 nePA66 zvinoburitsa kunhuhwirira kwakafanana neshinda yakatsva kana zvipikiri. PA6 inogadzira murazvo weyero, nepo PA66 ichitsva nemurazvo weblue. PA6 ine kuoma kuri nani, yakachipa pane PA66, uye ine nzvimbo yakaderera yekunyungudika (225°C). PA66 inopa simba repamusoro, kuramba kupfeka kuri nani, uye nzvimbo yepamusoro yekunyungudika (255°C).

Chechipiri, Misiyano muZvinhu Zvenyama:

• PA66:Kunyunguduka: 260-265 ° C; girazi shanduko yekushisa (yakaoma mamiriro): 50 ° C; density: 1.13–1.16 g/cm³.
• PA6:Semi-pachena kana opaque milky-white crystalline polymer pellets; kunyunguduka: 220 ° C; kuora kwekushisa: pamusoro pe310 ° C; kuwanda kwehama: 1.14; kubatwa kwemvura (maawa makumi maviri nemana mumvura pa23 ° C): 1.8%. Iyo ine yakanakisa kupfeka kusagadzikana uye yekuzvizora, yakakwira mechanical simba, yakanaka kupisa kupisa uye magetsi ekudzivirira emagetsi, yakanaka yakaderera-tembiricha kuita, kuzvidzimisa zvinhu, uye makemikari kuramba-kunyanya kuramba mafuta.

Kuenzaniswa nePA66, PA6 iri nyore kugadzira uye kuumbwa, inopa zvirinani kupenya kwepamusoro muzvigadzirwa zvakapedzwa, uye ine tembiricha yakapararira inoshandisika. Nekudaro, ine yakanyanya kunyura mvura uye ine hurombo dimensional kugadzikana. Iyo haina kuomarara, ine yakaderera kunyungudika, uye inogona kushandiswa kwenguva yakareba munzvimbo dzakaoma. Inochengetedza kumira zvakanaka kwekushushikana mukati metembiricha yakakura, ine tembiricha inoenderera ye105°C.

Chechitatu, Ungasarudza Sei Kushandisa PA66 kana PA6?
Kuenzanisa kwekuita pakati pePA6 nePA66:

• Mechanical properties: PA66> PA6
• Thermal performance: PA66> PA6
• Mutengo: PA66 > PA6
• Inonyungudika: PA66 > PA6
• Kutora mvura: PA6> PA66

Chechina, Misiyano muKushandisa Scope:

• PA6 engineering mapurasitikiIva nesimba rakanyanya kusimba, yakanaka kukanganisa kuramba, yakanakisa kupfeka kuramba, makemikari kuramba, uye yakadzikira friction coefficient. Kuburikidza nekugadziridzwa kwakadai segirazi fiber reinforcement, mineral filling, kana flame retardant additives, kuita kwavo kwese kunogona kuvandudzwa. Iwo anonyanya kushandiswa muindasitiri yemotokari uye zvemagetsi / zvemagetsi minda.
• PA66ine hukuru hwekuita hwese, hunosanganisira kusimba kwepamusoro, kusimba, kupikisa kupikisa, mafuta uye makemikari kuramba, kupfeka kuramba, uye kuzvizora. Iyo inonyanya kukurira mukuoma, kusimba, kupikisa kupisa, uye kuramba kukwira. Nekuda kwesimba rayo repamusoro kana ichienzaniswa nePA6, PA66 inonyanya kushandiswa mumaindasitiri ekushandisa senge tambo yekugadzira matayi.
