Chikopa cha PulUrethane, chomwe ndi chikopa chopangidwa ndi zinthu za poureurethane. Puather ndi chikopa chofala, chogwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana zamakampani, monga zovala, nsapato, mipando, zamkati, zamkati, mafakitale ena.
Kuchokera pazinthu zopanga ndi lingaliro la chilengedwe, purither zikopa zambiri zimagawidwa m'magulu awiri a Puather ndi zikopa zachikhalidwe.
1. Gawo loyamba popanga chikopa ndikupanga polyirethane, ndi polyteyanate (kapena polyyester, zopangira pouretethane zimachitika kudzera mu polyirethane.
2. Kukuta gawo lapansi, polyirethane utoto wokutidwa ndi zikopa za Puather, monga thonje, nsalu zopangidwa ndi polyyester.
3. Kukonza ndi chithandizo, gawo lapansi limakonzedwa ndikuthandizidwa, monga kuwerengera, kusindikiza, kupaka utoto ndi mawonekedwe ake. Njira zosinthira izi zimatha kupanga zikopa za Puther zimawoneka ngati zikopa zenizeni, kapena khalani ndi cholinga.
4. Chithandizo-Chithandizo: Nditamaliza kumaliza, Puthete ya Puther ingafunike kufika pamayendedwe ena, monga kutetezedwa, kutetezedwa ndi mankhwala, ndi zina.
5. Kuwongolera ndi Kuyesa: Mu magawo onse opanga, owongolera komanso kuyendera zidzachitika kuti zitsimikizidwe kuti chikopa cha Puch chimakumana ndi kapangidwe kake.
Kupanga ndondomeko yokonzanso PU Chikopa:
1. Sonkhanitsani ndi kubwezeretsanso katundu wa polyurethetthane, monga zinthu zakale za Puring, zotakatakamiza, mutatha kukonza ndi kuyeretsa zodetsa ndi dothi, kenako ndikuchepetsa chithandizo;
3. Gwiritsani ntchito chosakanizira kusakaniza tinthu kapena ufa wokhala ndi polsurethane spopors, mafayilo, ma antioxidat, ndikuwayika mu zida zatsopano zamankhwala kuti mupange matrorethane colrix. Matrurethane matrix amapangidwa mufilimu kapena mawonekedwe otchulidwa potaya, zokutira kapena zogulitsa.
4. Zinthu zomwe zimapangidwa zimatenthedwa, kuzimiririka ndikuchiritsidwa kuti zitsimikizire kuti zinthu ndi zolimba.
5.
6. Khazikitsani kuyendera kwaudindo kuti ipange miyezo yoyenera ndi zofunikira. Ndiye malinga ndi zofunikira za makasitomala, kudula mbali zosiyanasiyana ndi mawonekedwe a zikopa zomalizidwa;
Kudzera muzopanga, zitha kumvedwa kuti poyerekeza ndi zikopa zachikopa, pugy yobwezeretsanso Puthete imalipira chidwi ndi kuteteza zachilengedwe, kuchepetsa kuipitsidwa kwa chilengedwe. Tili ndi mafilimu a GRS a PU ndi PVC chikopa, chomwe chimalimbikitsa lingaliro la chitukuko ndi kuteteza zachilengedwe, ndikuchita mu chikopa.
