Potting Material ZveMagetsi Uye Maitiro Ekusarudza Zvakanakisa

Potting inogona kutsanangurwa senzira yekuzadza gungano remagetsi nechakasimba kuti riwedzere mazinga ekupikisa. Iyo inozivikanwawo se embedment uye inoita kuti zvikamu uye maassemblies arambe achizunguzika, kuvhunduka, zvinoparadza, makemikari, mvura, uye kunyangwe hunyoro nekupisa. Bhokisi rekubikira, kazhinji diki repurasitiki casing, rinoshandiswa kuisa zvinhu, zvakaita sePCB, uye resin iri mumhando yemvura inozadzwa uye yobva yabvumidzwa kurapa. Bhokisi racho rinogona zvakare kuve mhango mune yakakura yakavharirwa yekuchengetedzwa kwakasarudzika pane chaiyo gungano kana redunhu bhodhi nzvimbo.

Potting zvemagetsi seakadhindwa edunhu mabhodhi akawedzera dziviriro kubva pakudonha kwemagetsi, hunyoro, uye dzimwe njodzi dzinogona kuvakuvadza neimwe nzira. Kuvandudzwa kwekuita kwemagetsi uye dunhu rakavimbika ndezvimwe zvezvakanakira iwe zvauchawana kana iwe uchinge uchibika.

Iyo nzira zvakare inobatsira kuchengetedza vibration uye kuvhunduka kunokanganisa kushoma. Kukanganisa kwakadai kunogona kusiya zvemagetsi zvisisashande sezvo zvichikanganisa waya uye zvinongedzo. Mafungu eVibration pamabhodhi edunhu uye makesi avo zvakare anowedzera kushushikana zvichikonzera kutadza kwekutanga kwemagetsi. Paunenge uchibika, saka, iwe unowedzera hupenyu hwechishandiso nekureba sezvainozoramba vibration uye kuvhunduka mhedzisiro.

Potted electronics zvakare inodzivirirwa kubva kutsvina neguruva, izvo zvinogona kutungamira mukupisa, zvichikanganisa kumhanya, kuita, uye chiratidzo chemagetsi. Epoxy, urethane, uye silicone zvinhu zvikuru zvinoshandiswa mukugadzira. Nekutarisa maitiro uye zvimiro zveumwe neumwe, iwe unofanirwa kukwanisa kusarudza kuti ndeipi potting zvinhu zvemagetsi ndizvo zvakanakisisa. Nhau dzakanaka ndedzekuti iwe unogara uchiwana chinhu chinonyatsoenderana nezvido zvako zvekushandisa.

Epoxy potting compounds

Semuumbi wehari, epoxy inopa kunamatira kwakanaka uye saka inodzivirira zvikamu zvemagetsi kwenguva yakareba. Ichi chinhu chinoshanda chega pasina chikonzero chekuwedzera maprimers paunenge uchigadzira magetsi. Kusimba kwesimba, modulus, uye kusimba kunoita kuti ive sarudzo yakanaka kune akawanda emagetsi, kunyanya ayo ekushandisa kunze senge midziyo yekurima, ma transformer, uye switch.

Urethane potting compounds 

Sezvo a potting compound, kurebesa, kuchinjika, uye kuramba abrasion kunoita kuti ive sarudzo yakanaka, kunyanya kune zvakakosha zvikamu zvinoda kubata kwakapfava. Midziyo ine substrates segirazi, mapurasitiki, ceramics, uye masimbi alloys achada urethane sechinhu chekuumba.

Silicone potting compounds

Semuumbi wehari, kuchinjika kwesilicone kunoita kuti ive yakanaka kune mamwe maturusi. Iine yakanaka elongation zvimiro uye yakapfava uye inochinjika. Silicone inobatawo tembiricha yakakura uye inoita kushomeka kudiki pazvinhu zvemagetsi zvichienzaniswa ne epoxy.

Paunenge uchisarudza yakanakisa potting zvinhu zvemagetsi ako, unofanirwa kufunga zvinotevera:

Kuoma kwezvinhu. Epoxy uye urethane makomisheni anopa yakanakisa IP dziviriro, mamiriro ekunze, uye abrasion kuramba nekuti iwo akaoma kana achinge arapa. Silicone yakaomawo asi inoshanduka uye haina kuomarara seepoxy. Funga kuti kuoma kunoenderana nemagetsi ako uye sarudza zvinoenderana.

Material viscosity. Yakaderera viscosity inoshanda kune akawanda maapplication nekuti madhiri ega anozvikwirisa uye anoyerera zviri nyore sezvinodiwa. Iwe unogona, zvisinei, kusarudza zvinhu zvine yakakwira viscosity kana zvaunoda zvekushandisa zvichiraira kudaro.

Ruvara rwezvinhu. Clear Potting compounds inopa kuoneka kunyangwe mushure mekurapa uye yakanakira zvinhu zvakakosha zvinoda kuongororwa nguva nenguva. Rima opaque mavara akanaka mune mamwe maapplication, uye iwe unofanirwa kusarudza ruvara rwunonyatsoenderana nemagetsi.

Kupisa kwemafuta. Potting makomisheni ane yakakwira yekupisa conductivity inobvisa zviri nyore kupisa zvigadzirwa zvemagetsi zvinogadzira. Ese matatu makuru ekuputira zvinhu zvakanaka mune izvi, asi silicone inotora korona.

Vimba DeepMaterial kuti upe zvese zvikumbiro zvako neakakodzera uye emhando yekuumba makomisheni, zvinonamira, uye resin. Kuti uwane zvakawanda nezve potting zvinhu zvemagetsi uye maitiro ekusarudza zvakanakisa, unogona kubhadhara kushanya kuDeepMaterial pa https://www.epoxyadhesiveglue.com/category/pcb-potting-material/ nokuti zvimwe info.
