Nezve Chinhu Chisina Mvura yeMarambi e LED
Marambi ane dhizaini isina mvura anoshandisa kuzadza potting glue kuti uwane insulation uye kudzivirira mvura, uye shandisa sealant kubatanidza uye kuvhara majoini pakati pezvikamu zvechimiro kuita kuti zvinhu zvemagetsi zvipinde mhepo zvachose uye uwane kusapinda mvura kwemarambi ekunze.
1. Potting glue
Nekuvandudzwa kwetekinoroji yemidziyo isingapinde mvura, mhando dzakasiyana-siyana uye mabhureki ezvokunamira muhari zvemwenje nemarambi zvinoramba zvichionekwa, senge modified epoxy resin, modified polyurethane resin, uye modified silicone. Iyo kemikari formula yakasiyana, iyo elasticity, mamorekuru chimiro kugadzikana, adhesion, UV kuramba, kupisa kupisa, kushoma tembiricha kuramba, kudzoreredza mvura, kuita kwekudzivirira uye zvimwe zvemuviri uye kemikari mashandiro ezviratidzo zvepotting compound zvakasiyana.
Elasticity: Iyo colloid yakapfava uye elastic modulus idiki, saka kuchinjika kuri nani.
Molecular chimiro kugadzikana: Pasi pekuita kwenguva refu kweUV, mhepo uye yakakwirira uye yakaderera tembiricha, chimiro chemakemikari yechinhu chacho chakagadzikana pasina kuchembera uye kuputika.
Kunamatira: Kunamatira kwakasimba kunoita kuti zviome kupepeta.
Hydrophobicity: inoratidza kugona kweiyo colloid kuramba kupinda kwemvura.
Insulation: insulation ine hukama nezviratidzo zvekuchengetedza zvigadzirwa.
2. Kusunga chisimbiso
Sealants anowanzo tubular kurongedza, akakodzera gluing kuvaka, uye anowanzo shandiswa kubatanidza uye kuisa chisimbiso majoini pakati pewaya magumo uye shell zvimiro zvikamu. Inowanzo shandiswa single-component formula, inopindirana nehunyoro hwemhepo patembiricha yepakamuri, uye inoomesa zvega.
Nzira yekugadzirwa kwezvinhu zvisingapindi mvura yakareba. Imwe potting solidification cycle inotora maawa makumi maviri nemana. Mamwe magadzirirwo echigadzirwa akanyanya kuomarara uye anotoda 2 kusvika ku3 potting cycles, zvichikonzera kureba kwekutakura kutenderera uye nhamba huru yenzvimbo dzekugadzira.
