Kodi Kusiyanitsa Pakati pa Polyurethane ndi Epoxy Resin Ndi Chiyani?

1. Kufanana Ndi Kusiyana Pakati pa Polyurethane Ndi Epoxy Resin:

The Commonality:

1) Polyurethane ndi epoxy resin ndi zigawo ziwiri, ndipo zida ndi njira zogwirira ntchito ndizofanana;

2) Onse ali ndi kukana kwabwino kwamphamvu, osasweka, osagwa ndi zinthu zina;

3) Onse ali ndi katundu wotsutsa dzimbiri ku asidi amphamvu, alkali, mchere ndi zinthu zosiyanasiyana zamafuta;

4) Onsewa ali ndi mphamvu zoletsa fumbi, madzi, kukana kuvala pamwamba, kukana kupanikizika kwakukulu, kukana mphamvu ndi zina zotero;

Kusiyana kwake:

1) Polyurethane (PU) ndi polyphenylene diisocyanate ndi polyether polyol.Zimalumikizidwa ndikuchiritsidwa pamaso pa chothandizira triethylene diamine kupanga polima wapamwamba.Poyerekeza ndi epoxy resin, ndi poizoni kwambiri.

Polyurethane ali ndi makhalidwe abwino adhesion, kutchinjiriza ndi kukana nyengo.Kuuma kumatha kusinthidwa ndikusintha zomwe zili diisocyanate ndi polyether polyol, ndipo zitha kugwiritsidwa ntchito pakuyika zida zosiyanasiyana zamagetsi ndi zamagetsi.

2) Epoxy resin nthawi zambiri imakhala ndi bisphenol A epoxy resin, mankhwala ochiritsira (amine kapena acid anhydride), wothandizira wothandizira, filler, etc. Imakhala ndi nthawi yayitali yochiritsa kutentha kwa chipinda ndipo imatha kuchiritsidwa ndi kutentha.Pambuyo pochiritsa, imakhala ndi mphamvu yolumikizana kwambiri komanso kuuma.Nthawi zambiri, ndi yayikulu ndipo imatha kupangidwa kuti ikhale yowonekera kuti ipangitse ma module amagetsi ndi ma diode.

Polyurethane ili ndi mphamvu yolimbana ndi nyengo yabwino, simaphwanyidwa potentha kwambiri komanso yotsika, komanso ndi yokwera mtengo pang'ono.

2.kugwiritsa ntchito polyurethane ndi epoxy resin:

1) Polyurethane utomoni:

Utomoni wa polyurethane ndi zinthu za polima zomwe zimakhala ndi mphamvu zambiri, kukana misozi, kukana kuvala ndi zina;

Amagwiritsidwa ntchito ngatiodzigudubuza,malamba otumizira, mapaipi, zida zamagalimoto,nsapato za nsapato, zikopa zopangidwa, mawaya ndi zingwe ndi ziwalo zopangira zamankhwala, etc.;

Pakuti kupanga mankhwala pulasitiki, kuvala zosagwira kupanga mphira mankhwala, ulusi kupanga, okhwima ndi kusintha thovu mankhwala, zomatira ndi zokutira, etc.;

Amagwiritsidwa ntchito pomaliza matabwa osiyanasiyana, zida zamankhwala, zida zotumizirana mauthenga ndi zida ndi njira zosiyanasiyana zoyendera.

2)Epoxy utomoni: itha kugwiritsidwanso ntchito zokutira, zomatira, zinthu zophatikizika, etc.

Kupaka utomoni wa epoxy ndi mtundu wapamwamba kwambiri, wosavala komanso wokongola pansi, womwe uli ndi ubwino wosasunthika, mawonekedwe olimba, kukana mankhwala abwino, anti-corrosion, fumbi, kukonza bwino komanso kutsika mtengo.

Ma ziwembu osiyanasiyana amatha kupangidwa malinga ndi zomwe makasitomala amafuna, monga zokutira zosanjikiza zoonda, 1-5mm wandiweyani wodziyimira pawokha, odana ndi skid ndi kuvala zosagwira pansi, pansi pamatope, odana ndi malo amodzi, odana ndi dzimbiri, etc.

Zogulitsa ndizoyenera malo osiyanasiyana, monga ma workshop, zipinda zamakompyuta, malo osungiramo zinthu, ma labotale, ma ward, zipinda zogwirira ntchito, malo ochitira misonkhano, ndi zina.

3. Chovala choyambirira ndi choyenera kugwiritsidwa ntchito panja, pomwe chomalizacho ndi choyenera kugwiritsidwa ntchito m'nyumba;

Kufooka kwakukulu kapena kuipa kwa chotsiriziracho ndikuti kumawopa cheza champhamvu cha ultraviolet, ndipo chidzasanduka chikasu pansi pa cheza champhamvu cha ultraviolet, ndiko kuti, kuzimiririka, koma sichidzawola ndipo sichidzakhudza ntchito;

Komabe, zoyambazo zimakhala bwino kwambiri pakulimbana ndi nyengo kusiyana ndi zotsirizirazi, makamaka nthawi yachikasu yachikale ndi yotalika kwambiri kuposa yotsirizirayi, kotero kuti nthawi zambiri imagwiritsidwa ntchito pomanga panja.
