Kodi Mumadziwa Zambiri Zotani Zokhudza Elastane Isanu Zomwe Amagwiritsidwa Ntchito Kwambiri?

Kutanthauzira kwa elastane

Elastane ndiye chokoka chokhala ndi kutalika kwakukulu komanso kulimba mtima.Tanthauzo lachikale kwambiri ndiloti: "Mtundu wa ulusi umene kutentha kwa firiji, zinthuzo zimatambasulidwa mobwerezabwereza mpaka kuwirikiza kawiri kutalika kwake koyambirira, ndipo kukanidwa kukatulutsidwa, kumatha kubwezeretsanso kutalika koyambirira."Ndipo pazida za polyurethane, zimatanthawuza mtundu wa fiber womwe umatambasulidwa mpaka kutalika koyambirira katatu, ndipo kukangana kukatulutsidwa, kumatha kubwezeretsanso kutalika koyambirira.Kuphatikiza apo, m'maiko ndi zigawo zosiyanasiyana, pali matanthauzidwe ena.

Pakati pa mitundu yambiri yazinthu zomwe zimakhala ndi ntchito zosiyanasiyana, elastane, monga "makampani otuluka dzuwa", amatenga gawo losasinthika pazinthu monga kuvala chitonthozo, kufewa ndi kutentha kwa zovala popatsa munthu kukhudza bwino, motero amakhala ndi malo okhazikika. makampani opanga nsalu padziko lonse lapansi.Kupatula apo, chakhala chizoloŵezi chosapeŵeka kupatsa nsalu zansalu ndi zotanuka mumakampani opanga nsalu.

Mitundu ya common elastane

1. Alkene mtundu elastane (ulusi wa rabara)

Diolefins elastane imadziwika bwino kuti ulusi wa rabara kapena ulusi wotanuka, womwe utali wake nthawi zambiri umakhala pakati pa 100% mpaka 300%.Chigawo chachikulu cha mankhwala ake ndi sulfide polyisoprene.Ili ndi kukana kwabwino kwa kutentha kwapamwamba, kukana kwa asidi ndi alkali, kukana kuvala ndi zinthu zina zakuthupi ndi zakuthupi, zomwe zimagwiritsidwa ntchito kwambiri mu masokosi, ma cuffs okhala ndi nthiti ndi mafakitale ena oluka.Ulusi wa rabara ndi mtundu wa elastane womwe umagwiritsidwa ntchito koyambirira.Chifukwa chakuti amapangidwa makamaka kukhala ulusi wokwiririka, kugwiritsa ntchito kwake powomba nsalu kumakhala kochepa.

2. Ulusi wa polyurethane (spandex)Polyurethane elastane amatanthauza mtundu wa ulusi wopangidwa ndi chipika chopolymer chokhala ndi polycarbamate monga chigawo chachikulu.Spandex ndiye elastane yoyambilira komanso yogwiritsidwa ntchito kwambiri ndiukadaulo wopanga kwambiri.

3. Polyether ester elastane

4. Polyolefin elastane (DOW XLA CHIKWANGWANI)

5. Composite elastane (T400 CHIKWANGWANI)
