Chii chinonzi Dip Coating process

Mukuita dip coating process, substrate inonyikwa mune yemvura yekuputira mhinduro uye yobva yabviswa kubva kune mhinduro nekukurumidza inodzorwa. Coating ukobvu generally inowedzera nekukurumidza kubvisa kukurumidza. Ukobvu hunotarwa nechiyero chemasimba panzvimbo yekumira panzvimbo yemvura. Kukurumidza kubvisa kunokwevera mvura yakawanda kumusoro pamusoro pe substrate isati yawana nguva yekuyerera ichidzokera mumhinduro. Ukobvu hunonyanya kukanganiswa ne fluid viscosity, fluid density, uye kushushikana kwepamusoro.
Iyo waveguide kugadzirira ne dip-coating tekinoroji inogona kukamurwa mumatanho mana:

1. Kugadzirira kana kusarudzwa kwe substrate;
2. Nhete dzakatetepa deposition;
3. Kugadzirwa kwemafirimu;
4. Densification mukati mekurapa kwekupisa.

Dip coating, nepo yakanakisa kugadzira emhando yepamusoro, majasi eunifomu, inoda kudzora chaiko uye nzvimbo yakachena. Iyo yakapfekwa inogona kuramba yakanyorova kwevanomweral maminitsi kusvikira solvent yapera. Iyi nzira inogona kukurumidzirwa nekupisa kuomesa. Pamusoro pezvo, iyo yekupfeka inogona kurapwa nenzira dzakasiyana siyana dzinosanganisira dzakajairwa thermal, UV, kana IR matekiniki zvichienderana nekugadzirisa kwekugadzirisa mhinduro. Kana chigadziko charapwa, imwe layer inogona kuiswa pamusoro payo neimwe dip-coating / yekurapa maitiro. Nenzira iyi, yakawanda-layer AR stack inogadzirwa.
