Raws li qhov plaub polymer rau peb txoj kev tshawb, peb xaiv polybuthylene terephthalate (PBT), ib lub thermoplastic thermoplastic polymer uas belongs rau tsev neeg polyester, nws yog nws cov rigidity siab, tsis muaj kev xav plhom, siab zog, dimensional stability, thermal expansion coefficient, zoo hnav thiab kev ua hauj lwm tsis sib xws, tshuaj lom neeg kuj tsis haum, thiab tsis tshua muaj kev ya raws, thiab PBT tsuas yog siv hauv tsheb, cov neeg siv khoom, hluav taws xob, thiab textile industries thiab feem ntau hloov nrog qhov fillers, zoo ib yam li lwm cov polymers. Nws tau pom tias kev sib txuas ntawm qhov sib npaug ntawm kev sib txuas ua ke tau ua tau zoo dua qub rau cov khoom siv dag zog, xws li micro-hardness, indentation modulus, thiab indentation creep. Qhov tseem ceeb tshaj plaws yog los xaiv qhov kev tsim nyog ntawm kev sib raug ntawm cov hluav taws xob tawg paj, uas yog nyob rau hauv qhov teeb meem kev hloov kho, yog 132 thiab 66 kGy nyob rau hauv cov ntaub ntawv ntawm kev kho me ntsis. Qhov no nyob ntawm seb qhov twg yog qhov yuav tsum tau ua, yuav ua li cas los txhim kho nws, thiab rau cov ntawv thov.
Polyamides (PA) feem ntau pom lawv siv nyob hauv kev xyaum. Ob hom polamides tau siv, namely, Nylon 6 (PA6) thiab polyamide 9T (PA9T). Nylon 6 yog ib qho polyamide semi-crystalline aliphatic, uas zoo yog tsis muaj kev sib tsoo coefficient, muaj zog qaug zog, thiab muaj siab ua rau ntau hom tshuaj, roj, thiab roj hluav taws xob. Nws yog ib qho tseem ceeb ntawm kev siv tshuab polymer-Siv ib qho thoob plaws ntawm daim ntaub ntawv-Piv txwv, tsheb, kev tsim, tsheb thauj mus los, thiab lwm yam lag luam. Cov kws tshawb fawb Dadbin, Frounchi, thiab Goudarzi dealt nrog electron beam-crosslinked nylon 6, thiab cov kev hloov nyob rau hauv lub tshuaj absorbed tsuas rau nws cov khoom.
Raws li tus neeg sawv cev ntawm kev sib tw, cov neeg tshawb nrhiav siv TAC (triallyl cyanurate) thiab, rau cov hom phiaj sib thooj, lawv siv ib lub tshuab hluav taws xob electron nrog ib lub zog ntawm 5 MeV, nyob rau hauv irradiation koob ntawm 40 mus rau 150 kW. Cov no lees paub tias ntau tus nqi ntawm tus neeg sawv cev ntawm tus neeg sib tw tau muaj ntau yam kev cuam tshuam rau cov khoom polymer. Qhov ntau dua qhov dej ntawm cov dej tawg tau thiab ntau npaum li cas ntawm TAC, qhov txo qis dej ntawm polyamide 6. Crystallinity, nyob rau hauv ib txoj kev zoo sib xws, poob rau 1.2% thiab 3% TAC, nyob rau hauv txoj kab uas muaj cov kua ntau dua, sib piv nrog cov nkauj nylon nkauj 6 uas tsis muaj TAC.
Qhov kub ntawm qhov kub tshaj yog qhov qis tshaj ntawm 80 kW, uas yog 3% TAC, uas tuaj yeem siv rau kev xyaum ua haujlwm kom txo qis tus nqi. Yuav kom tau txais cov khoom zoo dua qub ntxiv, nws yog ib qho ua tau los txhawb cov polyamide los ntawm siv cov iav fiber ntau. Cov iav fiber ntau-reinforced polymer (GFRP) nruab nrab yog tsim kho tsim vim nws txoj kev tsim tshwj xeeb kev tsim tawm, kev ua haujlwm ntawm kev ua haujlwm, thiab kev ua kom muaj zog. Nws cov kev pab yog ib qho tseem ceeb vim kev nce qib tsis tshua muaj ntau thiab cov nqi erection. Porubska li al. kuaj xyuas cov nyhuv ntawm electron nqaj irradiation ntawm cov khoom ntawm cov nkauj thiab iav fiber ntau dua polyamide 6. Lawv tau txiav txim tias crosslinking ntau lig rau polyamide nkauj xwb vim qhov nce hauv tensile zog ntawm so thiab Young modulus. Cov khoom nyob rau hauv cov qoob loo tsis raug cuam tshuam los ntawm crosslinking, thermal resistance tsuas yog marginally cuam tshuam los ntawm irradiation rau ob leeg GFRD (marginal thawj), thiab rau polyamide nkauj xwb, nce me me. Lawv nrhiav tau tias hluav taws xob nqaj irradiation ua rau ntau cov kev hloov hauv cov khoom ntawm cov nkauj xwb polyamide hauv kev sib piv nrog GFRD.
Polyamide 9T (PA9T) yog ib qho tshiab, semi-muaj ntxhiab, kev kawm siab, kev siv cov tshuab ua polyamide. Qhov no polymer muaj ntev, yoog raws aliphatic linkage uas muaj cuaj methylene pawg nyob rau hauv ib theem sib lawv nyob hauv lub ntsiab aromatic polymer saw. Cov polymer no muaj qhov zoo tshuav ntawm kev tsim nqi thiab cov khoom, thiab muaj cua sov zoo, tsis yoojyim dej, hnyav ua haujlwm rau dej kub, kua qaub, alkali thiab organic solvents, thiab muaj cua sov ua kom siab. Vim muaj cov khoom no, PA9T siv rau hauv hluav taws xob, hluav taws xob, thiab tsheb yam. Vim yog qhov tseem ceeb, nws cov fiber ntau tam sim no tseem siv rau kev tsim cov nuv ntses nets thiab lwm yam khoom siv thiab textile.
