Chain extender imhando yezvinyorwa zvinogona kuwedzera ma molecular cheni uye kuwedzera iyo

molecular huremu nekuita neboka rinoshanda pane linear polymer cheni.

Inowanzo shandiswa kuvandudza ma mechanical properties uye kugadzirisa zvivakwa zve

polyurethane, polyester, naironi uye zvimwe zvigadzirwa.

Epoxy chain extender iketani inowedzera ine glycidyl methacrylate (GMA) .

Inowanzoshandiswa epoxy chain extenders inosanganisira styrene-glycidyl methacrylate, iyo ine

kugadzikana kwakanaka kwekupisa uye kunogona kupinda mhete-inovhura kemikari inopindirana nePA6, kwete

kusanganisa kwakachena kwemuviri.Inogona zvakare kushandiswa mumarara PET kudzokorodza uye zvimwe zvinhu.The

basa re epoxy chain extenders munylon yakagadziridzwa rakaita seinotevera:

1. Mhedzisiro pauremu hwemamorekuru uye intrinsic viscosity

Epoxy chain extenders inogona kuita neyekupedzisira amino boka uye yekupedzisira carboxyl boka re

PA6, uye wobva wavandudza huremu hwema molecular PA6.Zvisinei, gelation inogona kuitika panguva

iyo ketani yekuwedzera maitiro, saka zvinodikanwa kudzora akakodzera mamiriro, kunyanya

tembiricha uye screw kumhanya, kudzivirira kuyambuka-kubatanidza mune reactive extrusion.

Iyo intrinsic viscosity yePA6 yakawedzera nekukurumidza nekuwedzera kwehuwandu hweketani

extender.Kana zvirimo zveketani extender zvakawedzera kune imwe misa chikamu, iyo

intrinsic viscosity yePA6 yakadzikira zvishoma.Izvi zvinodaro nekuti iyo terminal boka rePA6 rinogona

ita nekukurumidza neboka re epoxy mucheni extender nekuda kwe polarity uye hydrogen

bond.Kana huwandu hweketani extender iri pakati nepakati, chikamu checheni refu

mamorekuru ari muhurongwa anowedzera uye viscosity inowedzera zvinoenderana;

Zvisinei, sezvomhinduro inoenderera, iyo yekupedzisira yeboka yePA6 inodzikira, uye kudhumhana

probability atkuguma kwema molecular cheni kunoderedzwa zvakanyanya nekuda kwesimba re

thermal diffusionuye kureba kwecheni ye molecular, kuwedzera, yakawandisa cheni extender

zvinogona kutungamirira kune adiki gel muhurongwa, izvo zvinotungamirira kuderera kwekuwedzera kweketani

kunyatsoshandauye PA6 intrinsic viscosity.

2. Mhedzisiro pamichina zvinhu

Iyo yakaenzana molecular mass yePA6 yakawedzerwa mushure mekuwedzera kweketani ne epoxy chain

extender, Kuoma kwezvinhu kunogona kuvandudzwa nekudzikira

crystallinity uye saizi yezviyo. Pamusoro pekuwedzera, nekuwedzera kwehurefu hwecheni yemamorekuru,

kusungirirwa pakati pemaketani kunowedzera, uye cheni ye molecular inonetsa kutsvedza.In

nenzira iyi, simba rekuita rinogona kutorwa nekuchinja kugadzirisa kwema molecular

cheni kana ichikanganiswa nenyika yekunze.Asi kana iyo misa chikamu chetani extender

inodarika imwe chikamu, zvese zvemakanika zvinhu zvinodzikiswa./n

3. Mhedzisiro pane rheological properties

Iyo melt flow rate (MFR) yakadzikira zvakanyanya nekuwedzera kwe epoxy chain extender,

zvichiratidza kuti epoxy chain extender uye PA6 yaive neanoshanda cheni yekuwedzera maitiro.

Nekuwedzera kwehuwandu hweketani extender, iyo equilibrium torque yakawedzera kekutanga

ndokuzodzikira, nekuti huremu hwemamorekuru hwePA6 mushure mekuwedzera ketani

yakawedzera, iyo inosungirirwa mucheni ye molecular yakawedzera, uye iyo yakanyunguduka viscosity zvakare

yakawedzera, nokudaro torque yekuenzanisa yakawedzera.

Nekufamba kwenguva, iyo PA6 pellet yakapfava, yakaumbwa uye yakanyungudutswa zvishoma nezvishoma, iyo

kushorwa kwe rotor kwakadzikira, uye torque zvakare yakaderera.
