Chigawo chimodzi chotchinga madzi
Chigawo chimodzi chotchingira madzi ndi chotchingira chopanda madzi cha polima cha mtundu wokhazikika wa filimu yochiritsira chinyezi.Amapangidwa ndi isocyanate ndi polyether monga chuma chachikulu, kusanganikirana ndi olimba wothandizira, plasticizers ndi zina zina ndi zina ntchito luso lapadera ndi kutentha madzi m'thupi polyurethane prepolymer ndi chinyezi mu mpweya, amene amapanga amphamvu, ofewa ndi jointless mphira madzi filimu pa gawo lapansi. .
Makhalidwe azinthu:
Single-gawo madzi ❖ kuyanika, yosavuta kugwiritsa ntchito, chofunika kuti chinyezi okhutira m'munsi si mkulu, angagwiritsidwe ntchito pa lonyowa pamwamba, likupezekanso pamwamba ndi chinyezi wachibale ndi lalikulu.
Filimu yokutira ya polyurethane imakhala ndi mphamvu zambiri komanso kutalika kwake, kukhazikika bwino, kutentha kwapamwamba komanso kukana kutentha pang'ono, komanso kusinthasintha kwa gawo lapansi ndikuchepa kwapakati ndi ming'alu.
Itha kuvala 1mm mpaka 3mm wandiweyani nthawi imodzi, filimu yokutidwa ndi wandiweyani, palibe thovu, komanso mphamvu yolumikizana kwambiri.
Osafunikira kutsuka wothandizila wa gawo lapansi pagawo laling'ono lomwe lili ndi muyezo
Kufikira koyenera:
Amagwiritsidwa ntchito kwambiri pamadenga, chipinda chapansi, chimbudzi, dziwe losambira, ndi mitundu yonse yamakampani komanso kutsekereza madzi
Tekinoloje yogwiritsira ntchito:
Gawo laling'ono liyenera kukhala lolimba, losalala, losasunthika, mkati mwa ngodya ndi ngodya yakunja iyenera kukhala yozungulira, m'mimba mwake ya ngodya yamkati ikhale yoposa 50mm, ndi coorder yakunja ikhale yoposa 10mm.
Zosakaniza ndi mlingo: molingana ndi mlingo wa ntchito, kusakaniza mozungulira o ntchito.
Mlingo wolozera: ❖ kuyanika filimu mlingo ndi za 1.3-1.5kg/sqm pamene makulidwe ndi 1mm.
Kupaka kwakukulu kopanda madzi, kuphimba kusakanikirana kosakanikirana ndi mphira kapena pulasitiki, makulidwe ake ndi osasunthika, nthawi zambiri ndi 1.5mm mpaka 2.0mm, ayenera kutsukidwa katatu mpaka 4, nthawi yomaliza kupukuta kuyenera kuchitidwa pambuyo pochiritsa kale. ndipo amakhala filimu, ndi kutsuka pa njira yokhazikika.Nthawi zambiri ngati filimu yosiyana, yopangira pulojekiti yapansi panthaka, iyenera kuyika zinthu zolimbitsa thupi zowonjezera.
❖ kuyanika makulidwe: mobisa ntchito makulidwe ndi 1.2 kuti 2.0mm, zambiri 1.5mm;ku chimbudzi makulidwe si osachepera 1.5mm;ku multilayer madzi a kukhudzidwa padenga kumanga makulidwe si osachepera 1.2mm;kwa wosanjikiza madzi a kalasi Ⅲ madzi, makulidwe si osachepera 2mm;
Ntchito yosanjikiza nsomba: kumwaza mchenga wotsukidwa usanathe nthawi yomaliza kutsuka sikunalimba.
Chitetezo chosanjikiza: pa zokutira filimu pamwamba ayenera kuchita kutchinjiriza chitetezo monga kapangidwe.
