Nplhaib-qhib polymerization yog cov txheej txheem additive tab sis nyhav muab condensation zoo li polymers tab sis ua raws li stoichiometry ntawm Ntxiv polymerization . Nylon 6 (tsim los thwart patent rau nylon 6, 6) yog tsim los ntawm Ntxiv polymerization , tab sis tshuaj zoo ib yam li polyamides.
Ib yam li ntawd, nws raug nug, yog nylon ntxiv lossis condensation polymer?
Ntxiv cov polymers muaj xws li polyethylene, polypropylene, Teflon, Lucite, thiab roj hmab. lwm. Condensation polymers suav nrog nylon , Dacron, thiab Formica.
Ib tug kuj yuav nug, hom polymer yog nylon? Nylon yog ib qho qauv tsim rau tsev neeg ntawm hluavtaws polymers, raws li aliphatic lossis semi-arromatic. polyamides . Nylon yog cov khoom siv thermoplastic silky uas tuaj yeem yaj-ua rau hauv fibers, films, lossis duab. Nws yog tsim los ntawm kev rov ua dua tshiab txuas los ntawm amide txuas zoo ib yam li peptide bonds hauv cov proteins.
Ib tug kuj nug, yog nylon 6 Ib qho ntxiv polymer?
Nws yog semicrystalline polyamide . Tsis zoo li feem ntau lwm cov nylons, nylon 6 tsis yog condensation polymer , tab sis es tsis txhob yog tsim los ntawm lub nplhaib-qhib polymerization ; qhov no ua rau nws muaj qhov tshwj xeeb hauv kev sib piv ntawm condensation thiab ntxiv polymers.
Puas yog Orlon ib qho ntxiv polymer?
Polymers muaj ntau qhov rov ua dua monomer units hauv cov saw ntev. A polymer Nws yog qhov zoo sib xws rau ib txoj hlua caj dab ua los ntawm ntau cov hlaws me me (monomers).
Lwm yam Ntxiv Polymers.
| Monomer | H2C = CH(CN) |
|---|---|
| Polymer npe | polyacrylonitrile |
| Lub npe lag luam | Orlon, Acrilan, Creslan |
| Siv | Fibers rau textiles, ntaub pua plag, upholstery |

Yuav ua li cas yog ib qho ntxiv polymer tsim?
Ib qho ntxiv polymer yog ib qho polymer uas tsim los ntawm kev sib txuas yooj yim ntawm monomers yam tsis muaj kev sib koom ua ke ntawm lwm cov khoom. Ntxiv polymerization txawv ntawm condensation polymerization, uas ua ke tsim cov khoom, feem ntau yog dej. Ntxiv cov polymers yog tsim los ntawm kev sib ntxiv ntawm qee qhov yooj yim monomer units rov ua dua
Vim li cas PVC yog ib qho ntxiv polymer?
(c) Polymerization ntawm chloroethene (vinyl chloride) Qhov no yog ib qho piv txwv ntawm ntxiv polymerization. PVC yog tsim los ntawm cov dawb radical polymerization hauv kev ncua. Thaum lub sij hawm polymerization, lub polymer precipitates tawm raws li nws yog tsim, vim nws yog insoluble nyob rau hauv lub monomer
Lub hauv paus ntsiab lus twg piav qhia tias vim li cas AFC poob qis thaum cov zis nce ntxiv cov ntsiab lus piav qhia vim li cas AVC nce ntxiv thaum cov zis nce ntxiv?
AFC poob qis vim qhov tso zis ntau ntxiv vim muaj kev sib kis. Tus nqi ruaj khov yog kis mus rau ntau dua thiab ntau dua units ntawm cov khoom tso tawm raws li cov zis ntau ntxiv. AVC nce raws li cov zis nce vim qhov txo qis rov qab los. Vim qhov txo qis rov qab mus rau kev ua haujlwm, nws raug nqi ntau dua los tsim txhua chav ntxiv ntawm cov zis
Puas yog nuclear yog ib qho khoom siv txuas ntxiv mus ntxiv?
Nuclear zog feem ntau yog suav hais tias yog lwm lub zog tsis txuas ntxiv dua tshiab. Txawm hais tias lub zog nuclear nws tus kheej yog lub zog tauj dua tshiab, cov khoom siv hauv nuclear fais fab nroj tsuag tsis yog. Nuclear zog sau lub zog muaj zog nyob rau hauv lub nucleus, los yog core, ntawm ib tug atom
Ib qho piv txwv ntawm ntxiv polymer yog dab tsi?
Polyolefins. Ntau qhov sib ntxiv polymers yog tsim los ntawm unsaturated monomers (feem ntau muaj C = C ob daim ntawv cog lus). Piv txwv ntawm cov polyolefins yog polyethenes, polypropylene, PVC, Teflon, Buna rubbers, polyacrylates, polystyrene, thiab PCTFE
