Kutheni Usebenzisa iTekhnoloji yeDip Spin Coating?

Iposwe kwi 2019-01-11Iimeko ezintathu zoshishino, ummiselo omnye kunye nokusebenza ezimbini ezinxulumeneyo ngabavelisi abaqhubela phambili beziqhoboshi, iikliphu kunye nezitampu ezincinci ezinxulumeneyo ukuba ziqwalasele ukusetyenziswa kwetekhnoloji yediphu yokugquma.
Okokuqala, abalawuli bendalo baqhubeka begxininisa ingqalelo yabo kwi-plating.Okwesibini, inani kunye nomthamo wezicelo ezifuna ukusebenza okuphezulu kokwambathisa ngokwetyuwa yokutshiza, ukukala kweKesternich kunye noxinzelelo lwe-torque oluhambelanayo luyanda.Ukufaka idip spin coating phezu kwepleyiti ye-zinc ebhityileyo ukugquma izinki yimpendulo esebenzayo neyonga imali.Iziphumo zovavanyo lwesitshizi setyuwa zinokunyuswa ukusuka kwiiyure ezingama-120 ukuya kwi-1,000 kusetyenziswa le ndlela.Ikwakhetheka kwezinye iindlela ezininzi ngokwembono yendalo esingqongileyo.Ekugqibeleni, i-hydrogen embrittlement yinkxalabo eqhubekayo, kwaye idiphu / i-spin ibonise amandla okunciphisa kakhulu okanye ukuphelisa le ngxaki.
I-Dip spin yinkqubo apho imveliso ifakwa kwi-mesh ye-mesh, ifakwe kwisisombululo sokugquma kwaye isonte ukuze isuse i-coating engaphezulu.Iqondo lobushushu kunye ne-viscosity yokugquma, ixesha lokuntywiliselwa, i-spin direction kunye ne-velocities kunye nendlela yokunyanga ziphakathi kwezinto ezivumela abasebenzisi ukuba benze iresiphi yenkqubo kwaye bafumane iziphumo ezichanekileyo, eziphindaphindiweyo.
Okunye okuqaphelekayo kukukwazi kwediphu/ukusonta ukunciphisa ixabiso lezinto zokugquma kunye nokulahlwa kwenkunkuma.Oku kungenxa yobuchwephesha obungama-98 pct okanye ngaphezulu kumndilili wogqithiselo olusebenzayo.
Iinkqubo zeDip spin ezifana nezo ziveliswe ziZixhobo ze-Spring, Portage, Michigan, ziluncedo kakhulu kumalungu amancinci aneekhontolo ezithile kunye nezo zinokugqunywa ngobuninzi ngaphandle kokunamathela omnye komnye.Kwaye ngelixa kukho ngaphandle okuphawulekayo (umenzi we-fastener omnye ulungisa iibholithi zakhe ezinobukhulu obungaphezulu kwe-dip / spin processing), ukuphumelela kwenkqubo efanelekileyo kuyenzeka kunye namacandelo angama-intshi ezili-10 okanye ngaphantsi ubude kwaye ngaphantsi kwee-intshi ezimbini ububanzi.
Ngelixa i-washers kunye nezinye izinto ezisicaba zigqitywe ngokufanelekileyo kunye nezinye iindlela, idiphu / i-spin ifaneleke ngokufanelekileyo ukuphahla kunye nezinye izibophelelo zokwakha, i-clamps, i-springs, i-o-rings, i-u-bolts, izikhonkwane kunye nezikrufu, ii-motor mounts kunye nezinye izixhobo ezininzi ezisetyenzisiweyo. ukugqiba oomatshini.
Itekhnoloji yeDip spin iyahambelana nazo zonke iintlobo zokwaleka ezinkulu ezisetyenziswa ekugqityweni kwe-fastener;ngokukodwa, iingubo ezidibanisa ukuchasana okuphezulu kwimichiza kunye ne-galvanic / i-bi-metallic corrosion kunye nokuzinza kwe-UV, iimpawu ezichasene ne-galling kunye / okanye i-anti-vibration.Uninzi luya kuhambelana nokutywinwa, izinto zokuncamathelisa kunye neziziba zokutshixa kwaye ziya komelela xa zinyangwa.Iindidi ezithile zokugquma ezibandakanyekayo ziquka ii-fluorocarbons, i-zinc-rich, i-ceramic metallics (i-aluminiyam-esekelwe kunye ne-organic ororganic topcoat) kunye neenkqubo eziphuma emanzini.
Inkqubo ye-dip spin iquka amanyathelo amathathu: 1) Ukucoca kunye nonyango lwangaphambili;2) Ukusetyenziswa kweeCoatings;kunye ne-3) Unyango.Abavelisi beFastener ngokuqhelekileyo basebenzisa i-grit ye-80- ukuya kwi-100-mesh ye-aluminium oxide ukususa i-oxides kunye nezikali zokunyanga ukushisa.I-Micro-, medium- or heavy-crystalline zinc phosphate lolona nyango luthandwayo apho lufuneka khona, nangona kukho iiconsi ezininzi zediphu/spin ezinokuthi zigalelwe phezu kwentsimbi engenanto.
Emva kokumisa, iinxalenye zilayishwa kwi-wire-mesh line-line basket.Ukuba ukulayisha kuyazenzekela, inkqubo ihambisa iinxalenye kwihopha yesikali sobunzima obunobunzima obusetwe kwangaphambili.Emva kokulayishwa, iinxalenye zithunyelwa kwigumbi le-dip / spin kunye neqonga elijikelezayo elijikelezayo apho livalelwe khona.Isitya sokugquma, esibekwe ngokuthe ngqo ngezantsi, siphakanyiswe ukuntywilisela ingobozi yamalungu kwindawo yokwaleka.
Xa ixesha lokuntywiliselwa ligqityiwe, isitya sokugquma siyehla siye kwindawo apho ingobozi isekwisikhongozeli, kodwa ingaphezulu komgangatho wolwelo.Ibhaskithi ke ibekwe phakathi.
Umjikelo oqhelekileyo wokusonta uya kuba licala elinye kuma-20 ukuya kuma-30 isekhondi, ibhuleki epheleleyo, emva koko ijikelezise umva kangangexesha elilinganayo.Isenzo sokuqhoboshwa siqhelanisa kwakhona iinxalenye ukuze zisuse ngokufanelekileyo ii-coatings kwimivalo.Xa idiphu/i-spin igqityiwe, isitya sokugquma siyathotywa ngokupheleleyo kwaye ibhaskithi ilungelelaniswe kwakhona, ivulwe kwaye isuswe.Ukulayishwa kwakhona kwenzeka kwaye inkqubo iyaphindwa.
Izinto zokugqoka zifakwe kwisitya sentsimbi kwaye zifakwe kwaye zisuswe ngomnyango wecala lokufikelela.Utshintsho lombala lufezwa kwi-10 ukuya kwi-15 min ngokususa nje isitya sokuqala sokugquma kunye nebhasikithi kwaye sitshintshe ngokutsha.Iingubo zigcinwe kwidiphu / i-spin container, evalwe ngentsimbi okanye i-polyethylene lid.Iibhaskithi ezinomnatha zicocwa kusetyenziswa i-solvent soak okanye igrit blast okanye i-mesh liner iyodwa isetyenzwa kwi-oveni etshileyo.
Iingubo ezimbalwa ezisetyenziswa kwi-fastener yokugqiba ukomisa umoya.Kwi-90 pct kunye nezifuna ubushushu, imigca encinci yediphu / spin ibandakanya i-oveni yebhetshi;izixhobo ezinkulu zibandakanya i-oveni yebhanti ehanjiswayo.Iibhanti zokuhambisa zilinganiswe kumalungu.Iinxalenye ezigqunyiweyo zilayishwa ngokuthe ngqo kwibhanti ye-oven kwaye zisasazeke ngesandla phezu kobubanzi.Okanye, zothulwa kwitreyi eshukumayo ebeka iindawo phezu kwebhanti ye-oveni ngokuzenzekelayo.
Imijikelezo yokuphilisa isukela ezintlanu ukuya kwi-30 min;iqondo eliphezulu lobushushu metal incopho yi 149 ukuba 316F.Isikhululo sokupholisa somoya ngenkani sibuyisela ubushushu bemveliso kwindawo ekufutshane.
Isixhobo seDip spin senziwa ngokobukhulu obulinganisiweyo ukuze kuqhutywe iimfuno.Apho iibhetshi zeemveliso zincinci kwaye kufuneka utshintsho oluninzi lwemibala, inkqubo encinci, ene-10-intshi yebhaskithi ye-diameter, umthamo we-750 lb / hr kunye nesantya sokujikeleza ukusuka kwi-zero ukuya kwi-900 rpm kuya kucetyiswa.Olu hlobo lwenkqubo luya kwamkela ukusebenza kwezandla, apho umqhubi ulayisha ibhasikidi kwaye asebenze idiphu kunye neenxalenye zemijikelezo esebenzisa iivalvu zesandla okanye i-automation inxalenye apho ukulayishwa / ukukhulula kusenziwa ngesandla, kodwa imijikelo ilawulwa yi-PLC.
Umatshini ophakathi, olungele uninzi lweevenkile zemisebenzi usebenzisa ibhaskithi eyi-intshi ezili-16 ububanzi kunye nomthamo osebenzisekayo we-cu ft. Umthamo umalunga ne-150 lbs.Le nkqubo iyakuthi iqhube ukuya kuthi ga kwi-4,000 lbs/hr yemveliso kunye nesantya sokujikeleza ukuya kuthi ga kwi-450 rpm.
Abona benzi bezinto zokuqhobosha ezinkulu kunye nokugqiba iivenkile zemisebenzi zisetyenziswa kakuhle ngokubanzi ngenkqubo esebenzisa ibhaskithi ye-intshi engama-24 edayamitha kwaye inesantya sokujikeleza ukuya kuma-400 rpm.
