PU utomoni & zokutira

Kufotokozera mwachidule:

Polyurethane kuponyera utomoni alipo mu makhalidwe onse ndi makulidwe.Ubwino wa PU resins ndi wochuluka monga mitundu yomwe ilipo.Polyurethane resins angagwiritsidwe ntchito mitundu yonse ya nkhungu ndi zitsanzo.Kuphatikiza apo, zitha kugwiritsidwanso ntchito pansi paukadaulo wa vacuum komanso m'makampani opanga.Utoto wa polyurethane umadziwika chifukwa cha kusungunuka kwawo komanso kusamva bwino komanso kukana mankhwala.

Kodi polyurethane ndi chiyani?

Polyurethane ndi pulasitiki yomwe imafupikitsidwa ngati PUR.Pulasitiki iyi ndi ya ma polima ndipo imakhala ndi magawo awiri osiyana: gawo lolimba ndi gawo lofewa.Chifukwa PU imakhala ndi zigawo zonse zolimba komanso zofewa, zinthuzo ndi zamtengo wapatali.Kupatula magawo awiriwa, PUR imathanso kugawidwa kukhala utomoni (wophimba) ndi thovu.

Pulasitiki ilipo mumitundu yonse ya 1- ndi 2-gawo.Zigawo ziwirizi zimakhala ndi chigawo A, utomoni woyambira, ndi gawo B, chowumitsa.Ndi polyurethane resins mumagwiritsa ntchito chowumitsa chapadera pagawo linalake la ntchito.Pambuyo powonjezera chowumitsa chamadzi ichi ku gawo la A, njira yamankhwala imachitika.Izi zimatsimikizira kuuma kwa utomoni.Kutengera mtundu wa harder, izi zidzakhudza liwiro ndi zinthu zakuthupi.Ndi ma PU ndikofunikira kusunga magawo oyenera.Kutengera mtundu wa gawo, zinthu zanu zizikhala zolimba kapena zotanuka mphira mutachiritsa.Ndi mtundu wa thovu, zinthuzo zimakulirakulira molingana ndi kuchuluka kwake.

Kugwiritsa ntchito polyurethane

Polyurethane resins angagwiritsidwe ntchito ngati zokutira, zoyambira, zomatira, lacquers, utoto kapena kuponyera utomoni.Monga mandala ndi UV zosagwira polyurethane utoto zitsulo kapena matabwa.Oyenera kumaliza parquet kapena pansi.Kuphatikiza apo, zinthuzi zimagwiritsidwanso ntchito ngati zikopa zopangira komanso zimagwiritsidwa ntchito muzitsulo za nsapato.

Kuthekera kwa ma resin a polyurethane kulibe malire ndipo kumafalikira m'magawo osiyanasiyana.

PU Cast pansi

Pansi pa polyurethane pansi pakhala kutchuka pamsika wapakhomo m'zaka zaposachedwa monga kumaliza kwa malo okhala, khitchini ndi zipinda zogona.Chifukwa cha mawonekedwe ake odziyimira pawokha, utomoni uwu umapanga mawonekedwe owoneka bwino komanso amakono.Zopezeka mumitundu yosiyanasiyana kuti zigwirizane ndi kamvekedwe ka mkati mwanu.Chifukwa cha zotanuka zake, mutha kuyigwiritsanso ntchito ndi kutentha kwapansi ndikupeza cholimba kwambiri komanso chosavala.

PUR utoto Sealine

Chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri ndi PU ndi ngati varnish kapena zokutira.Chifukwa cha kukana kwabwino kwa UV, utoto wa 2K polyurethane wakhala ukugwiritsidwa ntchito m'mafakitale kwa zaka zambiri.Makamaka m'magawo a mayendedwe, apanyanja ndi zomangamanga.Kukhazikika komanso gloss yayikulu kumapangitsa Sealine PUR kukhala kumaliza koyenera kupenta bwato lanu.
