Kushandiswa kwe epoxy resin adhesives

Epoxy resin adhesive(inonzi epoxy adhesive kana epoxy adhesive) yakaonekwa kubva munenge muna 1950, makore anopfuura makumi mashanu chete. Asi nepakati pezana remakore rechi20, zvakasiyana-siyana zvekunamatira dzidziso, pamwe chete nemakemikari anonamatira, adhesive rheology uye adhesive damage mechanism uye mamwe mabasa ekutsvakurudza anokosha mukufambira mberi kwakadzama, kuitira kuti maitiro ekunamatira, marudzi uye kushandiswa kwakakurumidza kufambira mberi. Epoxy resin uye yayo yekurapa sisitimu ine yakasarudzika, yakanakisa kuita uye nyowani epoxy resin, nyowani yekurapa mumiririri uye zvinowedzera zvinoramba zvichibuda, inova kirasi yeakakosha anonamira nekuita kwakanakisa, akawanda marudzi, kuchinjika kwakakura.
Epoxy resin adhesive mukuwedzera kune asiri-polar mapurasitiki akadai se polyolefin bonding haina kunaka, kune zvakasiyana siyana zvesimbi zvakaita sealuminium, simbi, simbi, mhangura: zvisiri-metallic zvinhu zvakaita segirazi, huni, kongiri, nezvimwe . Epoxy adhesive is structural adhesive inorema epoxy resin application.
Classification nekurapa mamiriro
Cold kuporesa adhesive (hapana kupisa kurapa adhesive). Zvakare yakakamurwa kuva:

• Kudzikira tembiricha kurapa adhesive, kurapa tembiricha <15 ℃;
• Tembiricha yekamuri inorapa inonamira, inorapa tembiricha 15-40 ℃.
• Kupisa kurapa adhesive. Inogona kugoverwa zvakare mu:
• Yepakati tembiricha inonamira, inorapa tembiricha inenge 80-120 ℃;
• Yakakwira tembiricha inonamira, tembiricha yekurapa> 150 ℃.
• Dzimwe nzira dzekurapa anonamira, senge mwenje unonamira unonamira, wakanyorova pamusoro uye mvura yekurapa inonamira, yakadzikama yekurapa inonamira.

Epoxy adhesives ane zvinotevera zvakanakira pane mamwe marudzi ekunamira:

1. Epoxy resinine mapoka akasiyana-siyana epolar uye anonyanya kushanda epoxy boka, nokudaro ine simba rinonamatira rakasimba rine zvakasiyana-siyana zvepolar zvinhu zvakadai sesimbi, girazi, simende, huni, mapurasitiki, nezvimwewo, kunyanya avo vane basa repamusoro, uye panguva imwe chete simba rakabatana re epoxy cured material yakakurawo, saka simba rayo rekunamatira rakakwirira zvikuru.
2. Iko hakuna kuderera kwema molecular volatiles inogadzirwa kana epoxy resin yarapwa. Iyo vhoriyamu shrinkage yeadhesive layer idiki, ingangoita 1% kusvika 2%, inova imwe yemhando ine diki kurapa shrinkage mu thermosetting resins. Mushure mekuwedzera filler inogona kuderedzwa kusvika pazasi 0.2%. Iyo coefficient yemutsara wekuwedzera weiyo epoxy yakarapwa zvinhu zvakare idiki kwazvo. Nokudaro, kushushikana kwemukati kuduku, uye kune zvishoma pane simba rekubatanidza. Mukuwedzera, iyo inokambaira ye epoxy yakarapwa zvinhu idiki, saka iyo dimensional kugadzikana kweiyo adhesive layer yakanaka.
3. Kune akawanda akasiyana enzvimbo, kurapa vamiririri uye modifiers, izvo zvinogona kurapa kuporesa, kupora kwemvura, nekudzikisira kwekuita tembiricha. Kukwegura kuramba, magetsi conductivity, magnetic conductivity, thermal conductivity, nezvimwewo).
4. Nezvakasiyana siyana organic zvinhu (monomer, resin, rubber) uye inorganic zvinhu (senge fillers, etc.) vane kuenderana kwakanaka uye reactivity, nyore copolymerization, crosslinking, blending, kuzadza uye mamwe magadzirirwo ekuvandudza mashandiro eiyo adhesive layer.
5. Good corrosion resistance uye dielectric properties. Kudzivirira kune acid, alkali, munyu, zvinonyungudutsa uye zvimwe zvinosvibisa media. Vhoriyamu resistivity 1013-1016Ω-cm, dielectric simba 16-35kV/mm.
6. General-chinangwa epoxy resins, kurapa maajenti uye zvinowedzerwa zvine kwakawanda kwakabva, kugadzirwa kukuru, kuri nyore kugadzira, kunogona kuve kusangana nekumanikidza kuumbwa, kunogona kuiswa pamwero mukuru.

Ungasarudza seiepoxy resin

Paunosarudza epoxy resin, pane zvakawanda zvekufunga nezvazvo, zvinosanganisira:

1. Shandisa: Iyo epoxy inogona kushandiswa kune yakajairika chinangwa kana mamwe maindasitiri maapplication?
2. Upenyu hwekushanda: Inguva yakareba sei iyo epoxy inoda kushandiswa isati yarapwa?
3. Kurapa Nguva: Zvichatora nguva yakareba sei kuti chigadzirwa chirapwe uye kunyatsorapwa uchishandisa epoxy?
4. Tembiricha: Chikamu chichashanda patembiricha ipi? Kana hunhu huchidikanwa, iyo epoxy yakasarudzwa yakaedzwa kunyanyisa kwekushisa?

Hunhu:

• High thixotropic properties, inogona kushandiswa kune façade kuvaka.
• Yakakwirira kuchengetedzwa kwezvakatipoteredza maitiro (solvent-isina kurapa system).
• High flexibility.
• High bonding simba.
• High magetsi insulation.
• Yakanakisa ma mechanical properties.
• Excellent tembiricha uye mvura kuramba.
• Yakanakisa kuchengetedza kugadzikana, nguva yekuchengetedza inosvika 1 gore.

Application:Yekubatanidza simbi dzakasiyana-siyana uye dzisiri-simbi, senge magineti, aluminium alloys, sensors, nezvimwe.
