1. The CommonalityAnd DchidwiBpakatiPolyurethaneAnd EpoxyResin:

TheKufanana:

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 zina;

3)Onse awiri ali ndi katundu wa dzimbiri kukana kwa asidi amphamvu, alkali, mchere ndi zosiyanasiyana mafuta zinthu;

4)Onse ali ndi katundu waosagwira fumbi, chosalowa madzi, kukana kuvala pamwamba, kukana kupanikizika kwakukulu, kukana kwamphamvu ndi zina zotero;

The Dchidwi:

1)Polyurethane (PU)ndi polyphenylene diisocyanate ndi polyether polyol.Ndi zolumikizana ndi mtanda     anachiritsidwa pamaso pa chothandizira triethylene diamine kupanga mkulu polima.Poyerekeza ndi epoxy resin, ndi poizoni kwambiri.

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

2)Epoxy utomoni nthawi zambiri amapangidwa ndi bisphenol A epoxy resin, machiritso (amine kapena asidi anhydride), wothandizira wothandizira, filler, ndi zina zotero. 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, mabomba, zida zamagalimoto, nsapato za nsapato, zikopa zopangira, mawaya ndi zingwe ndiziwalo zopangira mankhwalandi zina;

Popanga zinthu zapulasitiki, zinthu zopanga mphira zosamva kuvala, ulusi wopangira, chithovu cholimba komanso chosinthika katundu,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.
