Nayiloni ndi chiyani?Nayiloni yobwezerezedwanso ndi chiyani?
Nayiloni ndi dzina lodziwika bwino la banja la ma polima opangidwa ndi polyamides (magawo obwereza olumikizidwa ndi maulalo a amide).Nayiloni ndi silika ngati thermoplastic yomwe imapangidwa kuchokera ku petroleum yomwe imatha kusungunuka kukhala ulusi, mafilimu, kapena mawonekedwe.Ma polima a nayiloni amatha kusakanikirana ndi zowonjezera zosiyanasiyana kuti akwaniritse mitundu yosiyanasiyana ya katundu.Ma polima a nayiloni apeza ntchito zazikulu zamalonda pansalu ndi ulusi (zovala, pansi ndi kulimbitsa mphira), m'mawonekedwe (zigawo zoumbidwa zamagalimoto, zida zamagetsi, ndi zina zotero), komanso m'mafilimu (makamaka pakupanga chakudya. Nayiloni ndi polima, yopangidwa. Nayiloni yamasiku ano imapangidwa kuchokera ku petrochemical monomers (mankhwala omangira ma polima), kuphatikiza kupanga unyolo wautali kudzera mu condensation polymerisation reaction. Nayiloni yokonzedwanso ndi njira ina yopangidwa kuchokera ku zinyalala, nthawi zambiri, nayiloni imawononga kwambiri chilengedwe. zobwezerezedwanso m'munsi zipangizo.
Chifukwa chiyani Nylon yobwezerezedwanso ndi chinthu chokhazikika?
1.Nayiloni yokonzedwanso ndi njira yochepetsera zachilengedwe ku ulusi wapachiyambi chifukwa imadumpha njira yoipitsa.
2. Nayiloni Yobwezerezedwanso ili ndi ubwino wofanana ndi poliyesitala wobwezerezedwanso: Imapatutsa zinyalala kuchokera kumalo otayirako nthaka ndipo kapangidwe kake kamagwiritsa ntchito zinthu zocheperapo kuposa nayiloni yomwe ili ndi virgin (kuphatikiza madzi, mphamvu ndi mafuta otsalira).
3. Mbali yaikulu ya nayiloni yokonzedwanso imachokera ku maukonde akale osodza.Iyi ndi njira yabwino yothetsera zinyalala kuchokera kunyanja.Zimachokeranso ku makapeti a nayiloni, zothina, ndi zina.
4.Mosiyana ndi nayiloni yachikale yopangidwa kuchokera kumafuta osasinthika, nayiloni yobwezerezedwanso imapangidwa kuchokera ku nayiloni yomwe ilipo kale m'zinyalala.Izi zimachepetsa kwambiri chilengedwe cha nsalu (pa siteji yopezera zinthu, mulimonse).
5. Econyl ili ndi kutsika kwa kutentha kwa dziko mpaka 90% kuchepera poyerekeza ndi nayiloni wamba.Kuzindikira kuti chiwerengerocho sichinatsimikizidwe paokha.
6. Ukonde wotayidwa ukhoza kuwononga zamoyo zam'madzi ndikuchulukana pakapita nthawi, nayiloni yobwezerezedwanso imapangitsa kuti zinthu izi zigwiritsidwe ntchito bwino.
Chifukwa chiyani timasankha zinthu za nayiloni zobwezerezedwanso?
1.Kwa nayiloni, panthawi yopanga, mankhwala ambiri ofunikira amathera m'madzi-omwe pamapeto pake amathawa m'madzi pafupi ndi malo opangira.Izi siziri zovuta kwambiri za nayiloni padziko lapansi.Diamine acid iyenera kuphatikizidwa ndi asidi adipic kupanga nayiloni.Pakupanga asidi adipic, nitrous oxide yambiri imatulutsidwa mumlengalenga.Mpweya wotenthetsa dziko umenewu umakhala woopsa kwambiri chifukwa umaonedwa kuti ndi woopsa kwambiri ku chilengedwe chathu kuwirikiza ka 300 kuposa mpweya woipa.Mosiyana ndi ulusi wachilengedwe womwe umawonongeka pakapita zaka kapena zaka zambiri, nayiloni imatenga nthawi yayitali, monga zaka mazana ambiri.Ndiko kuti ngakhale kukathera kutayirako.Nthawi zambiri amangoponyedwa m'nyanja (monga maukonde otayidwa) kapena pamapeto pake amapeza njira yake.
2. Mosiyana ndi nayiloni yachikale yopangidwa kuchokera kumafuta osasinthika, nayiloni yobwezerezedwanso imapangidwa kuchokera ku nayiloni yomwe ilipo kale m'zinyalala.Izi zimachepetsa kwambiri chilengedwe cha nsalu (pa siteji yopezera zinthu, mulimonse).
3.Mtengo wa nayiloni wokonzedwanso ndi wofanana ndi wa nayiloni, ndipo ukhoza kutsika pamene ukutchuka kwambiri.
4. Nayiloni yobwezerezedwanso yalandira satifiketi kuchokera ku OEKO-TEX Standard 100, kuwonetsetsa kuti pachovala chomaliza mulibe mulingo wina wa kawopsedwe.
5. Matumba opangidwa kuchokera ku nayiloni yowonjezeredwa amawoneka okongola kwambiri, apamwamba komanso apamwamba kwambiri.Makasitomala amakonda zinthu izi.
