Selelekela sa litšobotsi tsa 3240 epoxy resin board

1. Mefuta e sa tšoaneng

Li-resin tse fapaneng, liakhente tse phekolang, le litsamaiso tsa ho fetola li ka batla li ikamahanya le litlhoko tsa lits’ebetso tse fapaneng foromong, ‘me mefuta e ka ba ho tloha ho viscosity e tlase haholo ho isa ho lintho tse tiileng tse qhibilihang.

2. Ho khomarela ka matla

Lihlopheng tsa tlhaho tsa polar hydroxyl le li-bond tsa ether ka har’a ketane ea molek’hule ea li-epoxy resin li etsa hore e khomarele haholo linthong tse fapaneng. The shrinkage ea epoxy resin e tlaase ha e phekoloa, ‘me khatello ea ka hare e hlahisoang e nyenyane, e thusang ho ntlafatsa matla a ho khomarela.

3. Pheko e bonolo

Khetha mefuta e fapaneng ea mefuta e fapaneng ea pheko, sistimi ea epoxy resin e ka batla e phekoleha maemong a mocheso a 0 ~ 180 ℃.

4. Thepa ea mechine

Sistimi ea epoxy resin e phekotsoeng e na le thepa e ntle haholo ea mochini.

5. Ho fokotseha ho fokolang

Boitšoaro lipakeng tsa resin ea epoxy le sesebelisoa se phekolang se sebelisitsoeng se etsoa ka karabelo e tobileng ea tlatsetso kapa karabelo ea ho bula li-polymerization ea lihlopha tsa epoxy ka har’a molek’hule ea resin, ‘me ha ho na metsi kapa lihlahisoa tse ling tse senyehang. Ha li bapisoa le li-resin tsa polyester tse sa tsitsang le li-phenolic resin, li bontša ho fokotseha haholo (ka tlase ho 2%) nakong ea ho phekola.

6. Botsitso ba mocheso

Mohlala o behoa ka ontong ka lihora tse 24 mocheso o boletsoeng ke index. Bokaholimo ba sampole ha boa lokela ho phatloha, ‘me ha hoa lokela ho ba le mapetsong a fetang 10mm botebong.

7. Ho cha

E boetse e tsejoa e le ho lieha ha lelakabe, ho itima lelakabe ho itimang, ho lieha ha lelakabe, ho hanyetsa mollo, ho chesa le lintho tse ling tse tukang ke ho hlahloba bokhoni ba thepa ea ho hanela ho tuka.
