Kodi kusiyana kwa PU glue strip ndi silicone strip ndi kotani?

Monga tikudziwira, pali ma IP rating ambiri a kuwala kwa LED, ma strip ambiri osalowa madzi amapangidwa ndi guluu wa PU kapena silicone. Ma strip onse a guluu wa PU ndi ma strip a silicone ndi ma strip omatira omwe amagwiritsidwa ntchito m'njira zosiyanasiyana. Komabe, amasiyana kapangidwe kake, mawonekedwe ake, ndi momwe amalangizidwira kugwiritsa ntchito.

Kapangidwe kake:

Guluu wa PU (Polyurethane): Guluu uwu wapangidwa ndi polyurethane. Guluu uwu umapangidwa pophatikiza polyol ndi isocyanate, zomwe zimapangitsa kuti guluu likhale lolimba komanso losinthasintha.
Mzere wa Silicone: Uwu ndi mzere womatira wopangidwa ndi silicone. Silicone ndi chinthu chopangidwa ndi ma polima a silicone omwe amatha kupirira kutentha kwambiri komanso kusinthasintha.

Katundu:

Mzere wa Guluu wa PU: Mizere yomatira ya PU imadziwika bwino chifukwa cha mphamvu zake zabwino zomangira, kukana chinyezi ndi mankhwala, komanso kusinthasintha. Imamatira bwino ku zipangizo zosiyanasiyana, kuphatikizapo matabwa, chitsulo, pulasitiki, ndi nsalu.

Zingwe zomatira za silicone sizimatentha kwambiri, sizimalowa madzi, ndipo zimakhala ndi mphamvu zabwino zotetezera kutentha. Nthawi zambiri zimagwiritsidwa ntchito pazinthu zomwe zimafuna zomatira zamphamvu, monga chitseko, zenera, ndi malo olumikizirana.

Kagwiritsidwe Ntchito Koyenera:

Mzere wa Guluu wa PU: Mizere yomatira ya PU imagwiritsidwa ntchito kwambiri m'magawo omanga, magalimoto, ndi mafakitale polumikiza ndi kutseka. Ndi yoyenera kulumikiza zipangizo zosiyanasiyana pamodzi, zomwe zimapangitsa kuti pakhale mgwirizano wolimba komanso wokhalitsa.
Zingwe zomatira za silicone nthawi zambiri zimagwiritsidwa ntchito potseka ndi kutchingira. Ndizoyenera kugwiritsa ntchito zomwe zimafuna kukana kutentha kwambiri, kukhudzana ndi mankhwala, komanso kulowa m'madzi. Makina a HVAC, mapanelo amagetsi, ndi zotchingira zamagalimoto zonse zimagwiritsa ntchito kwambiri zingwe za silicone.

Mwachidule, kusiyana kwakukulu pakati pa PU glue strip ndi silicone strip kumapezeka mu kapangidwe kake ndi makhalidwe ake. Silicone strip imapereka kukana kutentha bwino, kuletsa madzi kulowa, komanso kuteteza magetsi, pomwe PU glue strip imapereka mgwirizano wamphamvu komanso kusinthasintha. Chisankho pakati pa ziwirizi chimatsimikiziridwa ndi momwe zimagwiritsidwira ntchito payekhapayekha komanso makhalidwe omwe mukufuna.

Ngati mukufuna kudziwa zambiri zokhudza kupanga zinthu zokhudza mzere wa LED wosalowa madzi, kapena mzere wa SMD,Mzere wa COB/CSPndi mzere wamagetsi okwera, omasuka kuteroLumikizanani nafe!
