FAQ
Chii chinoita kuti silicone coating ive yakasiyana?
Kuvhara kwesilicone conformal kunoramba kuchichinjika kana tembiricha ikachinja. Kunovhara hunyoro zviri nani pane acrylic. Shandisa zvinhu zvakagadziriswa ne neutral chete. Mhando dzakagadziriswa ne acid dzinokuvadza majoini ako e solder nekufamba kwenguva.
Ungaisa sei silicone conformal coating nemazvo?
Kutanga, pisa bhodhi rako kusvika pa100–150°F. Danho iri rinobvisa hunyoro hwakavharirwa. Isa chifukidziro zvakaenzana. Shandisa silicone isina kuvharwa. Rega ipore zvizere usati waedza. Dunhu rako rinoramba rakachengetedzwa.
Ndechipi chiyero chemvura chaunoda pakushandisa magetsi ekunze?
IP67 inobata mita imwe yemvura kwemaminitsi makumi matatu. IP68 inodzika uye inogara kwenguva yakareba. Enzanisa chiyero chako nenzvimbo yako. Zvishandiso zvemugungwa zvinowanzoda IP68. Zvishandiso zvevatengi zvinowanzo shanda zvakanaka neIP67.
Ko silicone coating inopa dziviriro yehunyoro here?
Ehe. Kuputira kwesilicone kunoumba chipingamupinyi chinovhara hunyoro. Kunobata hunyoro nekuchinja kwetembiricha zvakanaka. Magetsi ako anowana dziviriro yakavimbika kubva mukuora uye mashort circuits.
