Ulusi wa nayiloni ndi mtundu wa ulusi wopangira, chigawo chake chachikulu ndi polyamide. Mapangidwe a maselo a ulusi wa nayiloni ali ndi makhalidwe awa: 1. Molekyu ya nayiloni imapangidwa ndi unyolo wa polyamide ndi wolowa m'malo, ndipo unyolo wa polyamide ndiye gawo lake lalikulu. Unyolo wa Polyamide nthawi zambiri umakhala ndi ma aliphatic binary amines ndi dibasic acid, omwe amapezeka kwambiri ndi sulfite anhydride ndi caprolactam. Magulu ambiri a amide (-Conh -) amapezeka m'mamolekyu a polyamide fiber, ndipo maguluwa amalumikizidwa ndi ma amide bond.
Ulusi wa nayiloni ndi mtundu wa ulusi wopangira, chigawo chake chachikulu ndi polyamide. Mapangidwe a maselo a nayiloni ali ndi izi:
1. Molekyu ya polyamide imapangidwa ndi unyolo wa polyamide ndi wolowa m'malo, ndipo unyolo wa polyamide ndiye gawo lake lalikulu la kapangidwe kake. Unyolo wa Polyamide nthawi zambiri umakhala ndi ma aliphatic binary amines ndi dibasic acid, omwe amapezeka kwambiri ndi sulfite anhydride ndi caprolactam. Magulu ambiri a amide (-Conh -) amapezeka m'mamolekyu a polyamide fiber, ndipo maguluwa amalumikizidwa ndi ma amide bond.
2, mamolekyu a polyamide fiber ali ndi magulu ambiri a methyl ndi methylene, maguluwa amapanga mamolekyu a polyamide kukhala ndi hydrophilicity yabwino, yosavuta kuyipitsa.
3. Unyolo wa polyamide mu molekyulu ya polyamide umalamulidwa kwambiri, kupanga dera linalake la crystalline, kotero kuti polyamide fiber imakhala ndi zinthu zabwino kwambiri zakuthupi ndi zamakina, monga mphamvu zambiri ndi kusungunuka.
4, CHIKWANGWANI cha nayiloni chimakhala ndi kukhazikika kwamafuta abwino komanso kukana kuvala, chimatha kukhalabe ndi mawonekedwe abwino pamatenthedwe apamwamba, osavuta kuvala.
Mapangidwe a ma cell a polyamide fiber amapangidwa makamaka ndi unyolo wa polyamide ndi gulu lolowa m'malo, unyolo wa polyamide ndiye gawo lake lalikulu. Chifukwa cha kukhalapo kwa magulu ambiri a amide ndi magulu a methyl/methylene m'mamolekyu ake, ali ndi hydrophilicity yabwino komanso kudetsa kosavuta.
Chifukwa ulusi wa nayiloni uli ndi mawonekedwe abwino komanso amakina, kukana kutentha, kukana kuvala komanso kuyatsa kosavuta ndi zabwino zina, umagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana, zina mwazinthu zazikulu zomwe zimagwiritsidwa ntchito ndi izi:
1, munda wa nsalu: ukhoza kugwiritsidwa ntchito kupanga mitundu yosiyanasiyana ya nsalu ndi nsalu, monga zovala zamkati, masokosi, masewera, kusambira, kuvala wamba, zovala zantchito, etc., kukana kwake kuvala ndi mphamvu ndi zina zimatha kupanga nsalu izi kukhala zabwino. moyo utumiki ndi chitonthozo.
2. Munda wa mafakitale: Amagwiritsidwanso ntchito kwambiri m'mafakitale, monga kupanga mipando ya galimoto, malamba, chingwe cha matayala, zingwe za mafakitale, zosefera ndi zinthu zina.
3, gawo la zida zomangira: zitha kugwiritsidwa ntchito kupanga zida zosiyanasiyana zonyamula, monga nsalu zolimba kwambiri, fiberboard, gasket, ndi zina zambiri, mphamvu zake zazikulu komanso kukana kuvala ndi zinthu zina zimatha kuteteza ma CD, kupanga kulongedza katundu kwambiri cholimba.
4, munda wokongoletsera kunyumba: itha kugwiritsidwanso ntchito kupanga zinthu zosiyanasiyana zokongoletsera kunyumba, monga kapeti, nsalu za sofa, makatani, zofunda, ndi zina zambiri, kufewa kwake ndi kukana kuvala ndi zinthu zina zimatha kupanga zida zokongoletsa zapanyumbazi kukhala zolimba.
5, malo azachipatala: angagwiritsidwe ntchito popanga zinthu zachipatala, monga mikanjo ya opaleshoni, masks, zosefera zamankhwala, ndi zina zambiri, mphamvu zake zazikulu komanso kukana kutentha ndi zinthu zina zimatha kutsimikizira chitetezo ndi moyo wantchito wamankhwala awa.
