bwanji mankhwala epoxy resin board

Resin, harderer, modifier systems zilipo kuti zigwirizane ndi zofunikira zonse za fomu yofunsira, kuyambira ma viscosity otsika kwambiri mpaka zolimba zosungunuka kwambiri. Mankhwala osiyanasiyana amagwiritsidwa ntchito pochiritsa, ndipo epoxy resin system imatha kuchiritsidwa pafupifupi kutentha kwa 0 mpaka 180 ° C.

1. Kumamatira mwamphamvu

Kukhalapo kwa polar hydroxyl ndi ma ether bond omwe amapezeka mumtundu wa molekyulu wa epoxy resin kumapangitsa kuti ikhale yomatira kwambiri kuzinthu zosiyanasiyana. Ma epoxy resins amakhala ndi kuchepa pang’ono pakuchiritsa komanso kupsinjika pang’ono kwamkati, zomwe zimathandiziranso kukulitsa mphamvu zomata.

2. Kufupikitsa mwamphamvu

Zomwe zimachitika pakati pa utomoni wa epoxy ndi mankhwala ochiritsira omwe amagwiritsidwa ntchito amachitidwa kudzera mu njira yowonjezera yowonjezera kapena phokoso lotsegula la polymerization la gulu la epoxy mu molekyulu ya utomoni, ndipo palibe madzi kapena zinthu zina zowonongeka zomwe zimatulutsidwa. Amawonetsa kuchepa kwambiri (osakwana 2%) panthawi yochiritsa poyerekeza ndi unsaturated polyester resins ndi phenolic resins.

3. Ntchito zamakina

Makina ochiritsidwa a epoxy resin ali ndi makina abwino kwambiri.

4. Ntchito yamagetsi

Makina ochiritsira a epoxy resin ndi zida zabwino zotetezera zomwe zimakhala ndi dielectric zambiri, kukana kutayikira kwamadzi komanso kukana kwa arc.

5. Kukhazikika kwamankhwala

Nthawi zambiri, makina ochiritsidwa a epoxy resin ali ndi kukana kwambiri kwa alkali, kukana kwa asidi komanso kukana zosungunulira. Monga ntchito zina zamakina ochiritsidwa a epoxy, kukhazikika kwamankhwala kumatengera utomoni wosankhidwa ndi wochiritsa. Kusankhidwa koyenera kwa epoxy resin ndi mankhwala ochiritsa kungapangitse kuti ikhale ndi ntchito yapadera yokhazikika yamankhwala.

6. Kukhazikika kwa sikelo

Kuphatikiza kwa zinthu zambiri zomwe zili pamwambazi kumapereka makina a epoxy resin kukhazikika komanso kukhazikika.

7. Kusamva nkhungu

Makina ochiritsidwa a epoxy amalimbana ndi nkhungu zambiri ndipo amatha kugwiritsidwa ntchito m’malo otentha kwambiri.
