Naylon da PTFE sune polymers na roba wanda aka fi amfani da su a masana'antar polymer.Nailan shine polyamide kuma polymer shine polymer fluoro.Dukansu biyu suna da babban nauyin kwayoyin halitta kuma suna da thermoplastics.PTFEphobic ne na ruwa, abu ne mai ƙarancin amsawa da sinadarai tare da babban ƙarfin wutar lantarki, da ƙarancin juzu'i.Nailan abu ne na siliki kuma madadin duka karafa ne da wadanda ba karafa ba, gami da tagulla, tagulla, itace, robobi, da roba.
Menene Nylon
Nylon shine polymer aliphatic, polyamide wanda aka fi amfani dashi a yawancin masana'antu.Nylons sune thermoplastics.Ana amfani dashi azaman ɗaukar hoto, kazalika da kayan lalacewa.Mafi yawan amfani da nailan shine maye gurbin tagulla, tagulla, ƙarfe, da aluminum.Bugu da ƙari, ana iya amfani da shi azaman madadin kayan itace, robobi, da roba ma.
Nylon wani abu ne na siliki wanda Wallace Carothers ya fara samarwa a cikin 1935. Ana samar da nailan daga halayen hexamethylenediamine tare da adicarboxylic acid (1: 1 ratio) a gaban ruwa, a cikin reactor.

Ana amfani da zaren nailan don samar da mayafin amarya, kirtani a cikin kayan kida, kafet, bututu, tanti, da kayan sutura.Hakanan ana amfani da ingantaccen nau'in nailan a wasu masana'antu don samar da combs da sassa na inji ciki har da gears da screws.Extrusion, simintin gyare-gyare, da gyare-gyaren allura sune dabarun da ake amfani da su don samar da nailan masu daraja.
Menene PTFE?
PTFE wani nau'in fluoropolymer na roba ne wanda kuma aka sani da polytetrafluoroethylene (PTFE).Wani abu ne da wani masanin kimiyar Dupont, Dokta Roy Plunkett ya gano cikin haɗari a cikin 1960, lokacin da yake aiki akan nemo wani madadin abu don dalilai na sanyaya.

Yana da ɗimbin amfani na kasuwanci saboda na musamman na zahiri da sinadarai.Abu ne na hydrophobic.Don haka, ruwa ko mafita da ke ɗauke da ruwa ba zai iya jika saman polymer ɗin ba.Ana amfani da polymer ko'ina a cikin kwanon dafa abinci marasa sanda azaman sutura.Hakanan ana amfani da wannan azaman mai mai tunda yana rage juzu'i.Tsarin haɗin kai na PTFE yana da kwanciyar hankali;don haka, yana da ƙananan amsawar sinadarai da babban wurin tafasa.Bugu da kari, yana da kyakykyawan ingancin wutar lantarki.polymer abu ne na thermoplastic, wanda ke nufin halayensa suna canzawa lokacin da aka zafi ko sanyaya.PTFE ya mallaki duk waɗannan kaddarorin masu amfani saboda tsarinsa na ƙwayoyin cuta.
Menene bambanci tsakanin Nylon da PTFE?
• Abubuwan sinadaran da ke cikin polymer nailan sune Carbon, Hydrogen, Oxygen, da Nitrogen.polymer ya ƙunshi Carbon da Fluorine kawai.
• Dukansu nailan da PTFE suna da intramolecular Forces, inda nailan shine "hydrogen bonds" kuma na polymer shine " dakarun watsawa na London."
• Nailan monomer (maimaitawa naúrar) shine (-NH-[CH2] 5-CO-) kuma na PTFE shine (-F2-CC-F2).
Nailan abu ne na ruwa yayin da PTFE abu ne na hydrophobic.
