Hais txog cov khoom Waterproof ntawm LED Teeb
Teeb nrog cov khoom siv tsis muaj dej tsis zoo siv cov kua nplaum ua kua nplaum kom ua tiav cov rwb thaiv tsev thiab cov dej tsis zoo, thiab siv cov sealant rau kev sib khi thiab kaw cov pob qij txha ntawm cov khoom siv los ua kom cov khoom siv hluav taws xob tag nrho airtight thiab ua tiav cov dej tsis zoo ntawm cov teeb sab nraum zoov.
1. Cov kua nplaum nplaum
Nrog rau txoj kev loj hlob ntawm cov khoom siv tsis muaj dej tsis zoo, ntau hom thiab hom tshwj xeeb potting nplaum nplaum rau cov teeb thiab teeb ci txuas ntxiv, xws li hloov kho epoxy resin, hloov polyurethane resin, thiab hloov silicone. Cov tshuaj formula sib txawv, lub elasticity, molecular qauv stability, adhesion, uV tsis kam, tshav kub tsis kam, tsis kub tsis kam, dej repellency, rwb thaiv tsev kev ua tau zoo thiab lwm yam kev ua tau zoo ntawm lub cev thiab tshuaj ntawm lub potting compound yog txawv.
Elasticity: Lub colloid yog mos thiab elastic modulus me dua, yog li qhov kev hloov pauv tau zoo dua.
Molecular qauv ruaj khov: Raws li kev ua haujlwm ntev ntawm uV, huab cua thiab siab thiab qis, cov qauv tshuaj ntawm cov khoom ruaj khov tsis muaj kev laus thiab tawg.
Adhesion: Muaj zog adhesion ua rau nws nyuaj rau tev tawm.
Hydrophobicity: qhia lub peev xwm ntawm colloid tiv thaiv dej nkag.
Rwb thaiv tsev: rwb thaiv tsev muaj feem xyuam rau cov khoom ntsuas kev nyab xeeb.
2. Cov nplaum nplaum
Cov sealants feem ntau yog ntim cov tubular, tsim nyog rau kev tsim kho gluing, thiab feem ntau yog siv rau kev sib txuas thiab sib khi cov pob qij txha ntawm cov xaim kawg thiab cov khoom siv plhaub. Feem ntau siv cov mis ib leeg, reacts nrog huab cua noo ntawm chav tsev kub, thiab solidifies lawm.
Cov txheej txheem tsim khoom ntawm cov khoom siv dej tsis zoo yog ntev. Ib lub voj voog ua kom lub cev muaj zog yuav siv sijhawm 24 teev. Qee cov qauv tsim khoom yog qhov nyuaj thiab txawm tias yuav tsum tau 2 mus rau 3 lub voj voog, ua rau lub voj voog xa khoom ntev thiab ntau qhov chaw tsim khoom.
