Litšobotsi tsa tšebeliso ea lipoleiti tsa insulating ke life
Litšobotsi tsa tšebeliso ea lipoleiti tsa insulating ke life
1. Mechini ea mechini. Sisteme e phekotsoeng ea epoxy resin e na le litšobotsi tse ntle haholo tsa mochini.
2. Pheko e bonolo. Khetha mefuta e fapaneng ea mahlahana a fapaneng a folisang, sistimi ea epoxy resin e kanna ea phekoloa mochesong oa 0 ~ 180 ℃.
3. Mefuta e fapaneng. Li-resin tse fapa-fapaneng, lisebelisoa tsa ho folisa le mekhoa ea ho fetola li ka ‘na tsa ikamahanya le litlhoko tsa likopo tse sa tšoaneng ka foromo,’ me moeli o ka ba ho tloha viscosity e tlase haholo ho isa ho lintho tse phahameng tse qhibilihisang.
4. Khomaretsi e matla. Lihlopha tsa tlhaho tsa polar hydroxyl le li-ether bond lihlopheng tsa limolek’hule tsa li-epoxy resin li etsa hore e khomarele lintho tse fapaneng. Ho fokotseha ha epoxy resin ho tlase ha ho phekoloa, mme khatello ea kahare e hlahisoang e nyane, e thusang ho ntlafatsa matla a mamarello.
5. Ho fokotseha ho fokolang. Karabelo lipakeng tsa epoxy lehoakhoa le sesebelisoa se phekolang se sebelisitsoeng e etsoa ka ho kopanya ka kotloloho kapa ho buloa ha lesale ka bongata ba lihlopha tsa epoxy ka har’a molek’hule ea lehoakhoa, ‘me ha ho na metsi kapa lihlahisoa tse ling tse sa lokang tse lokolloang. Ha li bapisoa le li-resin tsa polyester tse sa tšeloang le li-phenolic resin, li bonts’a shrinkage e tlase haholo (e ka tlase ho 2%) nakong ea ho folisa.
