Synthesis thiab kev tsim khoom
Nylon -6,6 yog synthesized los ntawm polycondensation ntawm hexamethylenediamine thiab adipic acid. Qhov sib npaug ntawm hexamethylenediamine thiab adipic acid yog ua ke nrog dej hauv lub reactor. Qhov no yog crystallized los ua nylon ntsev, ammonium / carboxylate sib tov
Yog li ntawd, nylon 6 synthesized li cas?
Nylon 6 yog synthesized los ntawm lub nplhaib-qhib polymerization ntawm caprolactam. Caprolactam muaj 6 carbons, li no ' Nylon 6 '. Thaum lub sij hawm polymerization, lub amide daim ntawv cog lus nyob rau hauv txhua caprolactam molecule yog tawg, nrog rau cov active pab pawg nyob rau hauv txhua sab rov tsim ob daim ntawv cog lus tshiab raws li cov monomer ua ib feem ntawm cov pob txha polymer.
Secondly, dab tsi byproduct yog tsim nyob rau hauv zus tau tej cov nylon? Nylons kuj tuaj yeem tsim los ntawm diamine thiab diacid chloride: Cov tshuaj tiv thaiv no mus los ntawm tib lub tswv yim, tab sis koj yuav tsum tau ntxiv me ntsis acid los ua ib qho catalyst. (Thaum koj ua nylon rau lwm txoj kev, adipic kua qaub ua raws li cov catalyst.) Tsis tas li ntawd, nws tsim HCl roj raws li cov khoom lag luam es tsis yog dej.
Tom qab, lo lus nug yog, qhov twg nylon ua?
Northeast Asia tseem yog qhov chaw nruab nrab ntawm lub ntiaj teb kev lag luam nylon fiber ntau. Hauv xyoo 2018, Asia muaj nyiaj ntau dua ob feem peb ntawm lub ntiaj teb cov khoom siv nylon fiber ntau (nrog rau Tuam Tshoj accounting rau 56% ntawm lub ntiaj teb no nylon fiber ntau lawm).
Nylon ua cov menyuam li cas?
Nws yog thawj hluavtaws fiber ntau los ua ua tag nrho los ntawm cov khoom xyaw inorganic - thee, dej thiab cua. Cov no yog tsim mus rau hauv cov tshuaj nruab nrab amine, hexamethylene diamine thiab adipic acid, uas yog ces polymerised. Qhov feem ntau variant yog nylon 6, 6, npe nylon 66.

Nylon cuam tshuam rau zej zog li cas?
Kev tsim cov nylon ua rau muaj kev tso tawm ntawm nitrous oxide, lub tsev cog khoom roj uas muaj txiaj ntsig zoo rau lub ntiaj teb ua kom sov. Txawm li cas los xij, nylon kuj tseem siv dej tsawg dua los tsim dua cov fibers ntuj, yog li qee qhov ntawm cov fibers cuam tshuam rau dej tau txo los ntawm qhov no
Puas yog Stainmaster ntaub pua plag ua los ntawm nylon?
Stainmaster ntaub pua plag yog ntau hom nylon fiber ntau lawv hu ua "hom 6.6." Hom fiber ntau tshwj xeeb no tau txais nws lub npe los ntawm ob txoj hlua ntawm carbon fiber. Thaum ob leeg nylon strands, lawv txawv me ntsis hauv cov qauv molecular uas tso cai rau cov fiber ntau coj mus rau lub caij nplooj ntoos hlav zoo li
Koj tuaj yeem qhia tau li cas yog tias cov yas yog nylon?
Txoj hauv kev yooj yim tshaj plaws los qhia yog tias cov yas yog Nylon yog nrhiav ib lub cim lossis lub thwj lossis embossing uas qhia koj cov khoom siv. Nylon poob rau hauv cov khoom siv rov ua dua tshiab ntawm "lwm yam", code 7, tab sis qee qhov chaw tsim khoom yuav muab lub npe ntawm cov khoom siv rau ntawm qhov chaw. Yog tias qhov ntawd tsis ua haujlwm, koj tuaj yeem sim qhov kev sim "hlawv"
Hom polymerization dab tsi tshwm sim rau daim nylon 6 6?
Txhawm rau pib, nylon yog tsim los ntawm cov tshuaj tiv thaiv uas yog cov txheej txheem loj hlob polymerization, thiab cov kua nplaum polymerization. Nylons yog tsim los ntawm diacids thiab diamines. Yog tias koj xav pom dab tsi adipic acid thiab hexamethylene diamine zoo li hauv 3-D, nyem qhov no
Nylon 6 tus nqi ntau npaum li cas?
Tam sim no: $ 1.23 txog $ 1.36, tib lub hauv paus. Nylon-6/6: Keeb Kwm (1997-2003): Siab, $ 1.64 ib phaus, nruab nrab txhua xyoo, inj. Chemical Profile - NYLON-6 thiab NYLON-6/6. US PRODUCER CAPACITY * Solutia, Pensacola, Fla. (6/6) 634 Tag Nrho Nylon Chip thiab Flake 3,286 Tag Nrho Nylon 4,571
