Kodi mungazindikire bwanji ndikusankha bwino pakati pa PA6 yosinthidwa ndi PA66 (Gawo 1)?

Ndi kukula kwa ukadaulo wosinthidwa wa R&D wa nayiloni, kuchuluka kwa kugwiritsa ntchito kwa PA6 ndi PA66 kwakula pang'onopang'ono. Opanga zinthu zambiri zapulasitiki kapena ogwiritsa ntchito zinthu zapulasitiki za nayiloni sakudziwa bwino kusiyana pakati pa PA6 ndi PA66. Kuphatikiza apo, popeza palibe kusiyana koonekera bwino pakati pa PA6 ndi PA66, izi zabweretsa chisokonezo chachikulu. Kodi PA6 ndi PA66 zingasiyanitsidwe bwanji, ndipo ziyenera kusankhidwa bwanji?

Choyamba, Malangizo Odziwira PA6 ndi PA66:
Ikapsa, PA6 ndi PA66 zonse zimatulutsa fungo lofanana ndi la ubweya kapena misomali yopsa. PA6 imapanga lawi lachikasu, pomwe PA66 imapsa ndi lawi labuluu. PA6 imakhala yolimba bwino, ndi yotsika mtengo kuposa PA66, ndipo imakhala ndi malo otsika osungunuka (225°C). PA66 imapereka mphamvu zambiri, kukana kuwonongeka bwino, komanso malo osungunuka kwambiri (255°C).

Chachiwiri, Kusiyana kwa Makhalidwe Athupi:

• PA66:Malo osungunuka: 260–265°C; kutentha kwa kusintha kwa galasi (mkhalidwe wouma): 50°C; kuchulukana: 1.13–1.16 g/cm³.
• PA6:Ma pellets a polymer oyera ngati mkaka ndi oyera pang'ono; malo osungunuka: 220°C; kutentha kwa kuwonongeka: kupitirira 310°C; kuchulukana: 1.14; kuyamwa madzi (maola 24 m'madzi pa 23°C): 1.8%. Ili ndi kukana kwabwino kwambiri kwa kuwonongeka ndi kudzipaka mafuta, mphamvu yamakina yambiri, kukana kutentha bwino komanso kutchinjiriza magetsi, kugwira ntchito bwino kutentha kochepa, kukana kuzimitsa, komanso kukana mankhwala—makamaka kukana mafuta.

Poyerekeza ndi PA66, PA6 ndi yosavuta kuikonza ndi kuiumba, imapereka kuwala kwabwino pamwamba pa zinthu zomalizidwa, ndipo imakhala ndi kutentha kosiyanasiyana komwe kungagwiritsidwe ntchito. Komabe, imayamwa madzi ambiri komanso imakhala yolimba pang'ono. Siilimba kwambiri, imakhala ndi malo otsika osungunuka, ndipo ingagwiritsidwe ntchito kwa nthawi yayitali m'malo ovuta. Imasunga kukana bwino kupsinjika pa kutentha kwakukulu, ndi kutentha kosalekeza kwa 105°C.

Chachitatu, Kodi Mungasankhe Bwanji Ngati Mungagwiritse Ntchito PA66 kapena PA6?
Kuyerekeza magwiridwe antchito pakati pa PA6 ndi PA66:

• Katundu wa makina: PA66 > PA6
• Magwiridwe antchito a kutentha: PA66 > PA6
• Mtengo: PA66 > PA6
• Malo osungunuka: PA66 > PA6
• Kuyamwa madzi: PA6 > PA66

Chachinayi, Kusiyana kwa Ntchito:

• Mapulasitiki aukadaulo a PA6Ali ndi mphamvu zokoka kwambiri, kukana kugwedezeka bwino, kukana kutopa kwambiri, kukana mankhwala, komanso kukana kupsinjika kochepa. Kudzera mu zosintha monga kulimbitsa ulusi wagalasi, kudzaza mchere, kapena zowonjezera zoletsa moto, magwiridwe antchito awo onse amatha kukulitsidwa. Amagwiritsidwa ntchito kwambiri m'makampani opanga magalimoto ndi zamagetsi/magetsi.
• PA66Ili ndi magwiridwe antchito abwino kwambiri, kuphatikizapo mphamvu zambiri, kulimba, kukana kugwedezeka, kukana mafuta ndi mankhwala, kukana kuvala, komanso kudzipaka mafuta okha. Imachita bwino kwambiri pakulimba, kulimba, kukana kutentha, komanso kukana kugwedezeka. Chifukwa cha mphamvu zake zambiri poyerekeza ndi PA6, PA66 imagwiritsidwa ntchito kwambiri m'mafakitale monga kupanga zingwe zamatayala.
