Nzira yekuziva uye kusarudza zvakanaka pakati pePA6 yakagadziridzwa nePA66 (Chikamu 2)?

Pfungwa 5: Ungasarudza Sei Pakati pePA6 nePA66?

1. Kana kudziya kwakanyanya kusingaderwi kupfuura 187°C, sarudza PA6+GF, sezvo isingadhuri zvakanyanya uye iri nyore kugadzirisa.
2. Pamashandisirwo anoda kuramba kupisa kwakanyanya, shandisa PA66+GF.
3. HDT (Heat Deflection Temperature) yePA66+30GF iri 250°C, nepo yePA6+30GF iri 220°C.

PA6 ine hunhu hwemakemikari nehwemuviri hwakafanana nePA66, asi ine nzvimbo yakaderera yekunyunguduka uye tembiricha yakakura yekugadzirisa. Inopa simba riri nani uye inodzivirira zvinonyunguduka kupfuura PA66 asi ine hunyoro hwakawanda. Sezvo hunhu hwakawanda hwezvikamu zvepurasitiki huchikanganiswa nekunyunguduka kwemvura, izvi zvinofanirwa kufungwa nezvazvo pakuronga zvigadzirwa zvine PA6.

Kuti ive nechokwadi chekuti PA6 ine hunhu hwemakanika, zvinhu zvakasiyana-siyana zvinogadziriswa zvinowanzowedzerwa. Fiber yegirazi chinhu chinowanzo shandiswa, uye rabha yekugadzira inogonawo kuiswa kuti iwedzere kusimba kwesimba.

Kune PA6 isina kusimbiswa, mwero wekudonha kwegirazi uri pakati pe1% ne1.5%. Kuwedzera girazi fiber kunogona kuderedza kudonha kusvika pa0.3% (kunyange zvazvo kwakakwira zvishoma munzira yakatarisana nekuyerera). Mwero wekudonha kwekupedzisira unonyanya kukanganiswa nekupenya kwekristaro uye kunyudzwa kwehunyoro.

Pfungwa 6: Musiyano muMaitiro Ekugadzira Jekiseni rePA6 nePA66

1. Kurapa Kuomesa:

• PA6 inonwisa hunyoro zviri nyore, saka kuomesa usati wagadzira kwakakosha.
  • Kana zvinhu zvacho zviri mupakeji isingapindi mvura, chengetai chigadziko chakavharwa.
  • Kana hunyoro hunopfuura 0.2%, iomesei mumhepo inopisa pa80°C kana kupfuura kwemaawa 3–4.
  • Kana ikaiswa mumhepo kwemaawa anopfuura masere, kuomesa ne vacuum pa 105°C kwemaawa 1-2 kunokurudzirwa.
  • Kuomesa kunobvisa hunyoro kunorayirwa.
• PA66 haidi kuomeswa kana chinhu chacho chakavharwa chisati chagadziriswa.
  • Kana mudziyo wekuchengetera wakavhurwa, uomese mumhepo inopisa pa85°C.
  • Kana hunyoro huchipfuura 0.2%, kuomesa ne vacuum pa 105°C kwemaawa 1-2 kunodiwa.
  • Chishandiso chekuomesa chinobvisa hunyoro chinokurudzirwa.

2. Kupisa Kwekuumba:

• PA6: 260–310°C (yemhando dzakasimbiswa: 280–320°C).
• PA66: 260–310°C (yemhando dzakasimbiswa: 280–320°C).
