Polyamide - Nsalu

Polyamide - nsalu za ulusi kupanga akamagwira ntchito mogwirizana njira zosiyanasiyana ndipo polyamide kasakaniza wazitsulo. Nthawi zambiri chifukwa cha nkhani ntchito polyamides za thupi aliphatic.

Kumasulidwa nsalu zosiyanasiyana pamaziko a polyamide wakhala anapezerapo mu mochedwa 60 ntchentche Mu zaka zapitazo. Kale mu zaka nsalu ladzala ndi zosiyanasiyana oonetsera ndi anawapatsa kwambiri kutentha kukana.

Masiku ano, mankhwala a minofu imeneyi ndi otchuka kwambiri padziko lonse lapansi, monga katundu kuthandiza zovala kwa nthawi yaitali kukhala wokongola. Mwa ubwino onse makamaka kuunikila zabwino mpweya permeability. Polyamide - nsalu ntchito kunadetsa kupanga sportswear, monga zinthu zotere cholimba, kuwala ndi softness.

Kuti polyamide nsalu kuti zofunika kuzikwaniritsa, zikhale za sayansi mwapadera otukuka, womwenso magawo atatu:

1. Mapangidwe ndi ulusi okha mwachindunji.
2. Kaphatikizidwe wa polima.
3. Nsalu Processing.

Polyamide - nsalu: katundu

Mwa makhalidwe makamaka kwa nsalu polymeric akhoza kutchulidwa mkulu kwamakokedwe mphamvu kapena katundu zina zimakhudza, ndi kuvala kukana. Polyamide - nsalu ndi kugonjetsedwa kwambiri mankhwala kapena reagents amuzolengedwa. Izo sasiya katundu wake atadziŵa kutentha wa ku madigiri 80 150, ndi osiyana kwambiri ndi ena mitundu ya nsalu. stabilizers osiyanasiyana amene ntchito popanga ulusi polyamide amayenda mkulu khalidwe la mankhwala chopangidwa. Aliyense CHIKWANGWANI zoterezi tilinazo mkulu zinthu magetsi (mwachitsanzo, malo amodzi). Choncho polyamide - minofu wotaya bata ake matenthedwe-zobwera chifukwa cha okosijeni pamaso kukhudzana komanso kuwala cheza (dzuwa). Pofuna kuthetsa zovuta izi, stabilizers wapadera anadzetsa nkhaniyo.

Polyamide nsalu amakonda kufunika kwambiri mu kupanga katundu ogula monga: mankhwala labala, zingwe, zida nsomba, zipangizo fyuluta ndi zina zotero. Textured ulusi umene pa chiyambi chake ndi mbali ya polyamide nsalu, ndi mu ankafuna kwambiri.

Tsopano thonje polyamide amapangidwa mu mawonekedwe a coils mosalekeza kapena ulusi chakudya amene ali mmaiko osiyana ndi mayina osiyanasiyana.

Kumene, nthawi zonse muyenera kutsatira malamulo luso la ntchito kwa polyamide nsalu sasiya katundu wake. Mwachitsanzo, akhoza kutsukidwa mu makina, koma kusunga pazipita kutentha boma 40 madigiri Celsius. Mode akamalimbikira ndi kuyanika zipangizo wapadera ayenera kuzipewa. Pambuyo kutsuka polyamide nsalu yokha uphwetsa mwachilungamo mofulumira, chomwe chiri chabwino katundu zakuthupi. Iron zinthu zimenezi ulusi polyamide, m'pofunika pa Kutentha wotsikitsitsa ndi wopanda nthunzi.
