Qhov Tseem Ceeb Qhov txawv - Polycarbonate vs ABS
Polycarbonate thiab ABS yog dav siv thermoplastic elastomers thiab muaj lawv cov khoom tshwj xeeb. Cov khoom no tau ua rau cov polymers no siv rau ntau yam kev siv. Qhov sib txawv tseem ceeb ntawm polycarbonate thiab ABS yog polycarbonate yog amorphous polymer ua los ntawm yaj polycondensation ntawm bisphenol A thiab diphenyl carbonate, whereas ABS yog ib tug polymer sib tov ua los ntawm acrylonitrile, butadiene, thiab styrene.
YPolycarbonate yog dab tsi?
Polycarbonate yog ib qho amorphous polymer nrog cov pob tshab zoo, siab tawv, thiab muaj kev cuam tshuam zoo heev. Ntxiv mus, nws muaj zoo heev creep kuj thiab zoo heev dimension stability. Qhov tseem ceeb tshaj plaws, polycarbonate yog qhov kub thiab txias (dhau 120 C); Yog li, nws yog qhov tsim nyog rau cov khoom uas tau ua kom tsis muaj zog autoclave sterilization. Tsis tas li ntawd, cov thermoplastic no muaj cov yam ntxwv hluav taws xob zoo thiab nws tus kheej tua hluav taws. Polycarbonate yog tsim los ntawm yaj polycondensation ntawm bisphenol A thiab diphenyl carbonate. Nws tuaj yeem ua tiav los ntawm kev txhaj tshuaj molding, thiab los ntawm extrusion tshuab-moulding.
Daim duab 01: Kev sib xyaw ntawm Polycarbonate
Cov ntaub ntawv pob tshab polycarbonate yog siv los ua cov lo ntsiab muag, lub qhov muag, lub thawv, lub teeb fittings, compact discs (CD), thiab cov khoom siv. Nws cov cuab yeej tiv taus kub kub tau raug txiav txim siab thaum ua cov tais diav kub, lub lauj kaub kas fes, tshuab ziab plaub hau thiab lwm yam khoom siv hauv tsev. Tsis tas li ntawd, nws muab kev cuam tshuam zoo heev thiab flexural zog rau lub twj tso kua mis impellers, cov kaus mom hlau, cov khoom siv me me, cov tais, cov khoom siv dav hlau, cov dej haus dispenser thiab qee cov ntawv ntim khoom. Cov qauv ntawm cov saw hlau polycarbonate tuaj yeem hloov pauv los ntawm kev sib ntxiv ntawm ntau yam radicals raws li pawg sab lossis hloov lub nplhaib benzene los ntawm carbon atoms. Qhov tsis zoo ntawm polycarbonate suav nrog nws qhov kub ua haujlwm siab, tsis zoo alkaline tsis kam, yuav tsum muaj kev ruaj ntseg ntawm ultraviolet, thiab tsis zoo aromatic hnyav tsis kam. Polycarbonate tuaj yeem sib xyaw nrog ABS rau ntau daim ntawv thov.
YABS yog dab tsi?
ABS thermoplastic resins yog tsim los ntawm peb hom monomers: acrylonitrile, butadiene, thiab styrene. Nws yog kev sib xyaw ntawm tag nrho peb cov monomer units. Txhua hom monomer muaj nws cov khoom. Piv txwv li, acrylonitrile muab tshuaj lom neeg thiab qaug zog tsis kam, hardness, thiab yaj lub zog, thaum butadiene muab kev cuam tshuam zoo. Ntxiv mus, styrene muab cov cua sov ua haujlwm, kev ua haujlwm, xim thiab hardness. Yog li ntawd, ABS muaj cov khoom tshwj xeeb xws li cuam tshuam tsis kam, kev ua haujlwm zoo, cov khoom siv kho tshuab zoo, kub kub distortion kub, thiab cov khoom gloss. Cov khoom no ua rau ABS siv dav hauv kev siv, suav nrog cov kav dej thiab cov khoom siv, cov cuab yeej siv thiab cov khoom siv vaj tsev, cov cuab yeej vaj tsev xws li cov cuab yeej siv tes, hluav taws xob ntsia hlau tsav tsheb, cov twj paj nruag tsheb thiab cov khoom siv hauv tsev.
Daim duab 02: Monomers ntawm ABS
Mass thiab emulsion polymerization thiab kev tshem tawm cov txheej txheem yog dav siv los tsim cov khoom siv ABS. Nplaim-retardant ABS yog tsim los ntawm cov nplaim hluav taws xob ntxiv (halogen-based organic compound), cuam tshuam kev hloov pauv, stabilizer, thiab roj nplua nyeem. Nplaim-retardant ABS yog dav siv los ua cov khoom siv automation xws li tshuab luam ntawv, tshuab luam ntawv thiab ntau yam khoom siv hluav taws xob hauv chaw ua haujlwm. Extrusion ntawm ABS yog siv los ua lub qhov rooj sab hauv ntawm lub tub yees, lub dab da dej, thiab qhov rooj npog.
