Yintoni ibhodi yesekethe yokwaleka ngokusesikweni?yintoni umphumo?

Indlela yokwenza iimveliso ezihlala ixesha elide kwiindawo ezinzima nazo ziyisihloko esibalulekileyo.Sizikhusela njani iimveliso zethu ezichanekileyo kwezi ziphumo ziyingozi?Ekuqaleni, izixhobo zombane zazikhuselwe yindlela ebizwa ngokuba yimbiza.Oku kuphunyezwa ngokuvalela izinto zombane kwindawo ebiyelweyo yeplastiki evulelekileyo kwelinye icala, efana nesixhobo sokutyala esimile ngendlela engaqhelekanga.Emva koko ugcwalise ngezinto ezingezizo zokuqhuba ezifana ne-acrylic okanye i-silicone.Oku kukhusela isixhobo kwindawo engaphandle, kodwa idla ixesha, ininzi, inzima kwaye ibiza kakhulu.Bambalwa kakhulu abantu abangaphandle kwabathengi basemkhosini okanye kwimizi-mveliso abanokusebenzisa ngokwenene.Njengoko izixhobo zombane ziba zincinci kwaye indawo, ubunzima, ixesha kunye neendleko zibaluleke ngakumbi, enye indlela yokomeleza iye yaxhaphaka ngakumbi: ukugqoka okuhambelanayo, umgangatho wokwaleka okuhambelanayo ngokubanzi Kukugquma ubukhulu obungaphantsi kwe-0.21mm.

Ukwambathisa ngokusesikweni kukusetyenziswa kwemathiriyeli ukugquma umphezulu wemveliso ukukhusela amacandelo e-elektroniki kwiindawo ezirhabaxa.Eyona nto ixhaphakileyo kukufuma.Amashishini ahlala esebenzisa i-conformal coatings nawo ayakhula, kodwa ngakumbi ezonyango, ezomkhosi, zaselwandle, ezemoto kunye nezoshishino.Iingubo zokwaleka ngokusesikweni zikwasetyenziswa rhoqo kwiimveliso ezithile ezigqityiweyo ezihlala zisesichengeni samanzi okanye kwiikhemikhali, ezinje ngoomatshini bokuhlamba izitya, oomatshini bokuhlamba, okanye naziphi na izixhobo ezenzelwe ukuba ngaphandle, ezifana neekhamera zokhuseleko.Ukongeza ekukhuseleni i-elektroniki, i-conformal coatings ingasetyenziswa kwi-cosmetic applications njengokongeza ukukrala okanye ukuchasana ne-oxidation kumphezulu (iidyasi ezicacileyo ezimotweni), ukongeza i-glossy okanye i-slick feels kwi-casings, ukongeza i-smudges / iminwe okanye ukuguqula iimpawu ze-optical properties. ilensi.

Indlela yokugcina ibhodi yesekethe?

Kukho iindlela ezahlukeneyo zokugubungela iibhodi zeesekethe, nganye kuzo idinga izinto ezahlukeneyo zokugquma ukuze zifezekiswe.Okokuqala, kufuneka unqume ukuba yintoni injongo yokugqoka.Ngaba ukhusela i-PCBA kwimozulu, ii-oyile ezahlukeneyo, ukungcangcazela koomatshini, ukungunda, njl.Izinto ezahlukeneyo zisetyenziselwa iinjongo ezahlukeneyo, kwaye ikhemistri esetyenziselwa ukugquma ichaza ngokuthe ngqo into enokuyifeza.Umzekelo, ukuba ufuna ukukhusela i-PCBA yakho kubumanzi kunye nesitshizi setyuwa, kwaye ufuna ukonyusa ukumelana ne-ESD, i-parylene iya kuba lukhetho oluhle.Nangona kunjalo, ukuba izinto ezikwi-PCBA zinovakalelo kubushushu okanye kwi-vacuum, i-parylene ayilokhetho lulungileyo kuba zombini izinto zikhona ngexesha lenkqubo yokwambathisa i-parylene.I-Acrylic ayikwazi ukwenza umbane omninzi, kodwa iyakukhusela i-PCBA yakho kumswakama kunye nokutshiza kwetyuwa.Inokusetyenziswa ngeendlela ezahlukeneyo kwiqondo lokushisa.

UHlelo kunye neMathiriyeli ekrwada yeeNgqungquthela eziQhelekileyo

I-Acrylics mhlawumbi iipende ezisetyenziswa ngokuqhelekileyo namhlanje.Ikwayeyona imathiriyeli inexabiso eliphantsi esetyenziswayo.Iingenelo zayo eziphambili ziindleko kunye nokulula ukuphatha, kodwa ikwanazo ezinye izinto ezingalunganga.Ubushushu buyayithambisa, kwaye iyatsha, nto leyo ethetha ukuba inokuba brittle phantsi kweemeko ezithile kwaye, njengezinye izinto zokungunda, isesichengeni sokonakala kweekhemikhali kunye nohlaselo lwebhayoloji.Ukuba kuphinda kusebenze kwakhona, kunokususwa ngokusebenzisa izinyibilikisi okanye ubushushu.

I-polyurethane enye isambatho esiqhelekileyo.Ngenxa yeempawu zayo ezityibilikayo ze-hydrophobic kunye ne-oleophobic, sisixhobo esihle kakhulu sokugquma.Nangona kunjalo, ezi zakhiwo zifanayo zithetha ukuba akunakufane ubambelele kweminye imiphezulu, kwaye ukuncipha kufuneka kuncitshiswe.Ukusebenza kwakhona kufuna izinyibilikisi ezikhethekileyo ukususa.

I-Silicones ineempawu ezikhethekileyo ezenza ukuba zibe neengubo ezincedo apho abanye bengekho.Iyakwazi ukumelana nokushisa okuphezulu, i-biologically kunye ne-chemically inert, kunye ne-hydrophobic kunye ne-oleophobic ngaxeshanye.Ezi propati zikwathetha ukuba kunzima ukudibanisa kunye nezinye izinto, kwaye amanyathelo okunciphisa kufuneka athathwe ukuthintela i-delamination.Ubume bayo berabha kunye nokunganyangeki kweekhemikhali kuthetha ukuba kufuneka isuswe ngomatshini ukuze iphinde isebenze.

I-epoxy resin yinto enzima kakhulu ekwanosetyenziso olukhethekileyo.Ukuqina kwayo kuthetha ukuba ingasetyenziselwa ukuqiniswa koomatshini, kodwa ngakumbi umdla ingasetyenziswa njengesixhobo sokhuseleko.Ukudibanisa i-epoxy kunye nezinye izinto, ezinje ngee-crossbar, zenza ulwakhiwo oluqinileyo oluya kuzitshabalalisa lona kunye nezixhobo ezikufutshane ukuba zizame ukwahlula ngomatshini kwi-PCBA.Ii-epoxies nazo ziyakwazi ukumelana nobushushu kunye neekhemikhali.Ukuqina kwayo kunye nexesha lokumisela nako kuyingozi njengoko kwandisa ixesha lokucubungula kwaye kwenza ukuba ukusebenza kwakhona kuphantse kungenzeki.

I-Nanocoatings sisisombululo esivelayo.Njengoko le teknoloji ikhula, iipropati kunye nokusebenza kwee-nanocoatings zivela ngokukhawuleza.I-solvent equkethe i-nanoparticles enqunyanyisiweyo isetyenziswe kwi-plate, kwaye ipleyiti emva koko yomiswe ngomoya okanye ibhakwe kwi-oven.I-oven iyanyibilika i-nanoparticles kwi-substrate efana neglasi.Ubume obuncinci be-nanocoatings buthetha ukuba banokunxiba kodwa kulula ukuphinda basebenze.
