Qhov sib txawv tseem ceeb ntawm Delrin thiab nylon yog Delrin yog cov thermoplastic ua los ntawm polyoxymethylene, hos nylon yog cov thermoplastic ua los ntawm cov tshuaj tiv thaiv ntawm amide thiab dicarboxylic acid.
Delrin yog lub npe lag luam rau cov khoom siv polymer polyoxymethylene lossis POM. Nylon yog ib hom polyamide uas yog hluavtaws.
Delrin yog dab tsi?
Delrin yog lub npe lag luam rau cov khoom siv polymer polyoxymethylene lossis POM. Nws tseem hu ua acetal, polyacetal, lossis polyformaldehyde hauv polymer chemistry. Nws yog ib yam khoom siv thermoplastic engineering uas muaj txiaj ntsig zoo hauv cov khoom precision uas yuav tsum tau muaj kev nruj nruj, tsis muaj kev sib txhuam, thiab qhov zoo ntawm qhov ntev. Delrin kuj yog ib hom khoom siv hluavtaws polymer. Cov khoom no yog tsim los ntawm cov tuam txhab tshuaj sib txawv nrog cov qauv sib txawv me ntsis, thiab cov no yog muag siv cov npe sib txawv, suav nrog Delrin, Kocetal, Ultraform, Celcon, thiab lwm yam.
Lub zog siab, hardness, thiab rigidity ntawm qhov kub qis heev yog cov yam ntxwv ntawm Derlin. Intrinsically, cov khoom no yog opaque dawb vim nws siab crystalline muaj pes tsawg leeg. Txawm li cas los xij, nws muaj nyob rau hauv cov xim sib txawv thiab ntawm kev lag luam nplai.
Thaum xav txog kev tsim khoom ntawm Delrin, peb tuaj yeem tsim nws hauv homopolymer lossis hauv daim ntawv copolymer. Peb tuaj yeem tsim cov homopolymer los ntawm cov tshuaj tiv thaiv ntawm aqueous formaldehyde nrog cawv los tsim cov hemiformal, lub cev qhuav dej ntawm hemiformal / dej sib tov, ua raws li kev tso tawm ntawm formaldehyde los ntawm cua sov lub hemiformal. Tom qab ntawd, lub hemiformal yog polymerized los ntawm anionic catalysis kom tau cov khoom xav tau.
Nylon yog dab tsi?
Nylon yog hom polyamide uas yog hluavtaws. Nws yog ib pawg ntawm cov polymers uas suav nrog cov yas. Peb tuaj yeem hu cov polymers no ua cov ntaub ntawv thermoplastic vim lawv cov khoom thermal. Qee cov tswv cuab ntawm pawg no suav nrog nylon 6. Nylon 6, 6, nylon 6.8. etc.
Hom polymer no belongs rau pawg polymer condensation vim yog txoj kev sib txuas. Nylon khoom yog tsim los ntawm condensation polymerization. Ntawm no, cov monomers siv hauv kev tsim cov nylon yog diamines thiab dicarboxylic acids. Lub condensation polymerization ntawm ob lub monomers tsim peptide bonds. Ib qho dej molecule yog tsim los ntawm txhua daim ntawv cog lus peptide raws li cov khoom lag luam.
Feem ntau ntawm cov ntaub ntawv nylon yog tsim los ntawm cov pob txha symmetrical thiab yog ib nrab-crystalline. Qhov no ua rau nylons zoo fibers. Lub npe ntawm daim ntawv nylon yog muab raws li tus naj npawb ntawm carbon atoms tam sim no nyob rau hauv diamine thiab dicarboxylic acid monomers. Piv txwv li, nyob rau hauv nylon 6, 6, muaj rau carbon atoms nyob rau hauv lub dicarboxylic acid thiab rau carbon atoms nyob rau hauv lub diamine.
Feem ntau, nylons yog cov ntaub ntawv tawv. Cov khoom no muaj tshuaj zoo thiab thermal kuj. Nylons tuaj yeem siv rau hauv qhov chaw kub kub. Qhov kub siab tshaj plaws uas nylon tuaj yeem siv tau yog 185 ° C. Cov iav hloov pauv kub ntawm nylon yog li 45 ° C. Lub iav hloov pauv kub ntawm lub polymer yog qhov kub ntawm qhov uas cov polymer hloov los ntawm cov khoom tawv, cov iav iav mus rau cov khoom muag muag, cov khoom siv roj hmab.
Qhov txawv ntawm Delrin thiab Nylon yog dab tsi?
Delrin thiab nylon yog cov khoom siv thermoplastic tseem ceeb. Qhov sib txawv tseem ceeb ntawm Delrin thiab nylon yog Delrin yog ib qho thermoplastic ua los ntawm polyoxymethylene, hos yog cov thermoplastic ua los ntawm cov tshuaj tiv thaiv ntawm amide thiab dicarboxylic acid. Ntxiv mus, Delrin yog ib qho tseem ceeb hauv kev tsim cov twj, valve Cheebtsam, lub zog, bearings, bushings, rollers, fittings, thiab lwm yam., hos nylon yog pab tau rau hauv cov khaub ncaws, thiab ntxiv dag zog rau hauv cov khoom siv roj hmab xws li tsheb tiers, ua hlua, raws li ib tug xov, etc.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm Delrin thiab nylon hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Delrin vs Nylon
Delrin yog lub npe lag luam rau cov khoom siv polymer polyoxymethylene lossis POM. Nylon yog ib hom polyamide uas yog hluavtaws. Qhov sib txawv tseem ceeb ntawm Delrin thiab nylon yog Delrin yog cov thermoplastic ua los ntawm polyoxymethylene, hos nylon yog ib qho thermoplastic ua los ntawm cov tshuaj tiv thaiv ntawm amide thiab dicarboxylic acid.
