Kev hloov kho tshuaj
Polyamide kub yaj nplaum tuaj yeem hloov kho tshuaj nyob rau hauv ob txoj kev: ua ntej, los ntawm kev qhia cov monomers tshiab, xws li tshiab polyamide nylon ntsev, heterocyclic amines, thiab hydrazines; Thib ob, los ntawm kev siv cov tshuab crosslinking copolymerization, los ntawm kev qhia cov pab pawg trifunctional xws li trimer acid, diethylenetriamine (los yog polyethylene polyamine), thiab glycerol (los yog polyether triol) rau hauv cov qauv polyamide raws li cov saw txuas ntxiv thiab crosslinkers, yog li txhim kho cov khoom lag luam daim ntawv cog lus lub zog thiab kub tsis kam.
Kev hloov kho lub cev
Kev hloov kho lub cev (kev hloov pauv hloov) yog lwm txoj hauv kev zoo rau kev hloov kho polyamide kub yaj nplaum. Los ntawm lub cev sib xyaw ethylene copolymer, styrene copolymers, thiab lwm yam ntaub ntawv nrog dimer acid-raws li PA resins, hloov dimer acid-raws li PA kub yaj nplaum nplaum nrog kev ua tau zoo tshaj tuaj yeem npaj tau.
