Mafala Akutoma Naworethane / Magalasi Agalasi

M'zaka zaposachedwa, poureurethane stute amapangitsa kuti mtundu wake ukhale wolimba chifukwa cha kulimba mtima kwake, kuchiritsa mwachangu osati utsi wa styrene. Ndi ukadaulo wa polyureurethane wowumba ndikuwongolera kuwongolera nthawi yake yofunsira, polyirethane walowa m'munda wazinthu zophatikizika ndi polyester ya polyester. M'mbuyomu zida zophatikizika za polyirethane zimapangidwa makamaka ndi njira ya jakisoni (Srimin Komabe, m'zaka zaposachedwa, ma cooctory a Polyirethane apanga matekinoloje monga ma cell, osambira ma polmurethane amapanga mafesi a pawindo kuti apange magalasi ndi magalimoto oyendayenda. Polyurethane kukoka kufinya nthawi zambiri kumakhala mamasukidwe otsika, okwanira kwambiri, amalimbikitsa mphamvu ndi kulimba mtima, komanso ntchito yayifupi. Poyerekeza ndi zida zina, kufinya ndi polsurethane kumatha kupanga zabwino zambiri. Itha kukonza zomwe zili ndi fiber galasi muzogulitsa ndikusintha mphamvu ya zinthuzo. Mwachitsanzo, ndi fiber fiber ndi polyirethane utoto, mphamvu yazenera lazenera limakhala lotalikirapo. Nthawi yomweyo, chifukwa mapangidwe a pawindo a polyurethane sakhala opanda phokoso, samaswa ndipo amakhala olimba. Zinthu zambiri zophatikizira polyurethane / galasi fibesi ndi mtundu wamphamvu kwambiri, molyder yolimba ya polyrety nkhani yolimba ngati zinthu zolimbitsa thupi, pogwiritsa ntchito kukoka kopitilira. Malonda a polurethane-polentrakiti amangokhala ndi mphamvu zambiri komanso kutentha kwabwino kuposa zida zachikhalidwe, komanso kuteteza kopepuka ndi zachilengedwe. Mapulogalamu ake ndi otakata kwambiri, kuchokera pa bafa lokongola, kuti liziyenda bwino ndi skis, zophatikizika ndi mitundu ina yopanga, gulu lina la poureurethan lidaphatikizidwa mu moyo wathu watsiku ndi tsiku. Amanenedwa kuti m'zaka zochepa zapitazi, kufunikira kwa China kwazinthu zophatikizira kwakhala kukuwonjezeka. Zinthu zophatikizira ndi zinthu zapamwamba, zomwe zimawonjezera mawonekedwe a zinthu zingapo kuti zitheke. Anthu opanga ma polyirethane akopa chidwi chachikulu ndi mafakitale onse chifukwa cha malo awo apadera, mphamvu zazikulu komanso zolimba, komanso kuthekera kwawo kothandiza kwambiri. Makamaka pomanga ndi mafakitale oyenda, matekinolojeni opanga ndi mapulogalamu ndi ochulukirapo
