Lintlha tse tharo tse ka sehloohong tse amang ho phekola ka sekhomaretsi

Karabelo ea ho folisa ea likhomaretsi ke ts'ebetso e hlahisang le ho ntlafatsa thepa e joalo ka matla a tlamahano ka karabelo ea lik'hemik'hale (polymerization le crosslinking). Ho folisa ke mohato oa bohlokoa oa ho fihlela ts'ebetso e ntle ea maqhama; matla a mangata a tlamahano a ka finyelloa feela ha ho phekoloa ka ho feletseng. Mabapi le nako ea ho phekola, e arotsoe ka mekhahlelo e meraro: pheko ea pele, pheko ea mantlha le kamorao-ho folisa.

Ho phekola ha pele ho bolela hore ka mor'a nako e itseng mocheso o tsitsitseng, sekhomaretsi se fumana matla a itseng, bokaholimo ba sona bo thatafala 'me ha bo khomarele, empa ha bo e-s'o fole ka ho feletseng.

Pheko ea mantlha e bolela ka mor'a hore nako e fete, lihlopha tse ngata tse sebetsang hantle li nka karolo karabelong ea lik'hemik'hale 'me li fihle boemong bo itseng ba li-crosslink.

Post-ho phekola ho bolela ho phekola likarolo tse tlanngoeng ka mor'a pholiso ea mantlha ho ntlafatsa ts'ebetso ea bonding kapa ho fihlela litlhoko tsa ts'ebetso. Hangata re li boloka mocheso o tsitsitseng ka nako e itseng. Mohato ona o eketsehileng o phethela pheko, o phahamisa boemo ba ho folisa ho feta, o tlosa khatello ea kelello hantle 'me o etsa hore maqhama a be matla.

Ho fumana sekhomaretsi se phekotsoeng hantle, mokhoa oa ho folisa o tlameha ho etsahala tlasa maemo a nepahetseng. Mokhoa oa ho phekola oa li-adhesive o ama haholo boleng ba ho kopanya. Ho na le mekhoa e meraro ea motheo ea ho phekola: mocheso, khatello le nako. Lintlha tsena tse tharo li na le tšusumetso e kholo mabapi le hore na likhomaretsi li phekola joang.

Lintlha tse tharo tse kholo tse amang ho phekola ka sekhomaretsi

1. Mocheso oa ho folisa ke e 'ngoe ea likarolo tsa bohlokoa bakeng sa ho folisa sekhomaretsi. Haeba mocheso o le holimo haholo, sekhomaretsi se tla phalla habonolo kapa sekhomaretsi se tla fetoha brittle, se theole matla a ho kopanya. Haeba mocheso o le tlase haholo, limolek'hule tsa thepa ea motheo ha li khone ho tsamaea ka bolokolohi. Sena se lebisa ho sekhahla se tlase sa li-crosslink le ho folisa ho sa phethahalang. Kahoo re tlameha ho laola mocheso ka thata nakong ea ho phekola, kaha sekhomaretsi se seng le se seng se na le mocheso oa sona o loketseng oa ho phekola.

2. Ho folisa khatello ho bolela ho sebelisa khatello e itseng nakong ea ho folisa ho thusa sekhomaretsi se tlamahane hantle le lintho tse tlamiloeng le ho tiisa boleng bo botle, 'me li-adhesives tse fapaneng li hloka khatello e fapaneng e ka aroloa ka mefuta e meraro: khatello ea ho kopana e sebelisa feela boima ba lintho tse tlamahaneng ntle le khatello e eketsehileng, e loketseng sekhomaretsi sa epoxy, α-cyanoacrylate sekhomaretsi, sekhomaretsi sa acrylic sekhomaretsi, sekhomaretsi sa polyurethane le polyester unsaturated; khatello ea 0.1~0.3 MPa e sebetsa ho solvent-based adhesives ho kenyeletsa phenolic-acetal glue, phenolic-nitrile butadiene glue, epoxy-nitrile butadiene glue, epoxy-nylon glue le polyimide glue; khatello ea 0.3 ~ 0.5 MPa ke ea filimi, phofo, tube, li-adhesives tsa pellet le sekhomaretsi se chesang se qhibilihisang, 'me khatello e phahameng e ka ntlafatsa ho ba metsi.

3. Nako ea ho folisa e bolela nako e hlokahalang bakeng sa tlamahano e feletseng tlas'a mocheso o tsitsitseng le khatello. Likhomaretsi tse fapaneng li na le lebelo le fapaneng la ho folisa: α-cyanoacrylate glue le hot melt glue li phekola hang-hang; kamore-mocheso ka potlako-phekola sekhomaretsi sa epoxy le sa bobeli-sekhomaretsi sa acrylic sa moloko ho nka lihora tse 'maloa; Sekhomaretsi sa epoxy polyamide se hloka matsatsi a 'maloa ho fola ka botlalo. Ntle le moo, nako ea ho folisa e angoa ke mocheso le khatello. Mocheso o phahameng o khutsufatsa nako ea ho folisa, ha mocheso o tlase o o eketsa haholo, 'me li-glues tse ling li ka' na tsa se ke tsa fola ka matsatsi a mangata haeba li bolokiloe ka tlas'a mocheso oa kamore.
