Makhalidwe a ntchito ya epoxy glass fiber chubu:

Chubu cha epoxy glass fiber chimapangidwa ndi nsalu yagalasi yagalasi yopanda alkali yomwe imayikidwa ndi utomoni wa epoxy, ndipo imawotchedwa ndikuwotcha-panikizidwa mu nkhungu. Ndodo yozungulira imakhala ndi ntchito yapamwamba yamakina. Dielectric ntchito ndi machinability wabwino. Itha kugwiritsidwa ntchito ngati zida zotchingira zida zamagetsi, malo achinyezi ndi mafuta osinthira.

Maonekedwe a chubu cha epoxy glass fiber: Pamwamba payenera kukhala yosalala komanso yosalala, yopanda thovu, mafuta ndi zonyansa. Mtundu wosagwirizana, zokopa, kusagwirizana pang’ono ndi ming’alu zimaloledwa kumapeto kapena mbali ya epoxy galasi fiber chitoliro chomwe makulidwe awo amaposa 3mm.

Makhalidwe a ntchito ya epoxy glass fiber chubu:

1. Mitundu yosiyanasiyana. Ma resins osiyanasiyana, machiritso ndi makina osinthira amatha kukwaniritsa zofunikira pakugwiritsa ntchito mosiyanasiyana, ndipo kuchuluka kwake kumatha kukhala kocheperako kwambiri mpaka zolimba zosungunuka kwambiri.

2. Kuchiritsa bwino. Pogwiritsa ntchito machiritso osiyanasiyana, makina a epoxy resin amatha kuchiritsidwa pa kutentha koyambira 0 mpaka 180 ° C.

3. Kumamatira mwamphamvu. Pali magulu a polar hydroxyl ndi ma ether chain mu unyolo wa epoxy resin, womwe umapangitsa kuti ikhale yomatira kwambiri kuzinthu zosiyanasiyana. Epoxy resin imakhala ndi kufupikitsa pang’ono komanso kupsinjika kwamkati mkati mwa kuchiritsa, zomwe zimathandizanso kukulitsa mphamvu yolumikizana.

4. Kufupikitsa kochepa. Zomwe zimachitika pakati pa epoxy resin ndi kuchiritsa wothandizila zimachitika mwachindunji kuwonjezera anachita kapena mphete-kutsegula polymerization wa epoxide mu utomoni molekyulu, popanda madzi kapena kusakhazikika zina mwa mankhwala. Poyerekeza ndi unsaturated polyester resins ndi phenolic resins, amawonetsa kufupikitsa kochepa kwambiri (osakwana 2%).

5. Ntchito zamakina. Makina ochiritsidwa a epoxy ali ndi ntchito zabwino zamakina.
