Unokudzidzisa sei kusarudza epoxy resin kurapa mumiririri?

An epoxy curing agent ikemikari inoshandiswa kurapaepoxy resinskuburikidza nekuita makemikari nemapoka epoxy mu epoxy resin kuti iite chimiro chemuchinjikwa, zvichiita kuti epoxy resin ive yakaoma, yakasimba yakasimba.
Basa rekutanga re epoxy kurapa maajenti nderekuwedzera kuoma, abrasion kuramba, uye makemikari kuramba epoxy resins, achiaita chinhu chinogara kwenguva refu uye chakasimba, icho chiri chikamu chakakosha cheepoxy pultruded composite. Ichi chinyorwa chinogovera nzira yekusarudza iyo chaiyo epoxy-kurapa mumiriri zvichienderana nezvinhu zvakasiyana:
Maererano nekurapa mamiriro
- Kurapa pane tembiricha yekamuri: Kana kukurumidza kurapa pane tembiricha yekamuri kuchidikanwa, aliphatic amine kurapa maajenti akadai se ethylenediamine uye diethylenetriamine anogona kusarudzwa; kana kukurumidza kuporesa kusingadiwi kuti kuve kwakakwirira, uye kutarisa panguva yekushanda, polyamide kuporesa vamiririri vanogona kusarudzwa.
- Kurapa kwekupisa: Kune yakakwira kupisa kupisa uye michina zvivakwa, inonhuhwirira amine kurapa maajenti, akadai diaminodiphenylsulfone (DDS), nezvimwewo, inogona kushandiswa; kune yakaderera-tembiricha kukurumidza kurapa, yakagadziridzwa amine kurapa maajenti ane accelerator anogona kutariswa.
- Kurapa pasi pemamiriro akakosha: kurapa munzvimbo ine hunyoro, inonyorovesa kurapa inorapa mumiriri inogona kusarudzwa; kune mwenje wekurapa sisitimu, mumiriri wekurapa ane photoinitiator uye epoxy acrylate inogona kusarudzwa.
Maererano nezvinodiwa zvekuita
- Mechanical zvivakwa: kana kuomarara kwakanyanya uye kusimba kwakanyanya kuchidikanwa, anhydride kurapa vamiririri vanogona kusarudzwa; kana kuchinjika kwakanaka uye kupikisa kuramba kuchidikanwa, kuomesa kurapa maajenti akadai se polysulfide rabha akanyanya kukodzera.
- Chemical kuramba: yakakwirira zvinodiwa muasidhi, alkali, uye solvent kuramba,phenolic resinkurapa mumiririri kana imwe yakagadziridzwa amine kurapa mumiririri inonyanya kukodzera.
- Kupikiswa kwekupisa: Kwenzvimbo dzepamusoro-tembiricha, senge pamusoro pe200 ℃, silicone inorapa agent kana kurapa mumiriri ine polyaromatic chimiro inogona kutariswa.
Zvinoenderana nemamiriro ekushandiswa
- Indoor nharaunda: yakakwira kuchengetedzwa kwezvakatipoteredza zvinodiwa, mvura-yakavakirwa epoxy kurapa mumiririri kana yakaderera volatile aliphatic amine kurapa mumiririri inonyanya kukodzera.
-Kunze nharaunda: kunaka kwemamiriro ekunze kunodiwa, alicyclic amine kurapa maajenti ane yakanaka UV kuramba akanyanya kukodzera.
-Nzvimbo dzakakosha: Munzvimbo dzine hutsanana hwakanyanya sechikafu nemishonga, isiri-chepfu kana yakaderera-chepfu epoxy kurapa maajenti akadai seyekuchengetedza chikafu akasimbiswa polyamide kurapa maajenti anoda kusarudzwa.
Funga nezvezvinodiwa pakuita
-Kushanda nguva: Kwenguva yakareba yekushanda, sarudza yakadzikama yekurapa mumiririri, senge dicyandiamide, nezvimwe. Kuti ushande pfupi uye nguva yekurapa, sarudza kukurumidza kurapa aliphatic amine kurapa mumiririri.
- Kurapa Chitarisiko: Kuti chitarisiko chisina ruvara uye chakajeka chinorapa, sarudza alicyclic amine kurapa maamine, nezvimwewo. Nekuda kweruvara rwakaderera, sarudza yakaderera-mutengo general kurapa maamine.
Yakasanganiswa nemutengo wemari
-Pasi pechimiro chekusangana nezvinodiwa zvekuita, enzanisa mutengo uye dosage yeakasiyana anorapa vamiririri. Mutengo weakajairwa amine kurapa maamine wakadzikira, nepo mamwe akakosha ekurapa maajenti akadai senge fluorine-ine uye silicone-ine kurapa maajenti anodhura.
