Ukuhlaziywa Kobuchwepheshe Ekuvimbelweni Manzi Kwezakhiwo Nezinto ezibonakalayo kwezibani ze-LED zangaphandle
Mayelana nokuvinjelwa kwamanzi okubalulekile
Idizayini yezibani ezingangeni manzi, ukusetshenziswa kweglue yokugcwalisa i-filler ukuze kufakwe amanzi, ukusetshenziswa kwe-sealant bonding phakathi kwesakhiwo esivaliwe phakathi kwama-seams, ukuze izingxenye zikagesi zingabi namoya ngokuphelele, ukufeza indima yokuvikela isibani sangaphandle.
1) Gcwalisa ingcina
Ngokuthuthuka kobuchwepheshe bezinto ezingangeni manzi, izinhlobo ezahlukahlukene nemikhiqizo yeglue efakwe isibani ethize ihlala ivela, ngokwesibonelo, i-epoxy resin eguquliwe, i-polyurethane resin eguquliwe, i-silicone eguquliwe nokunye. Ifomula yamakhemikhali ihlukile, ukuqina, ukuqina kwesakhiwo samangqamuzana, ukunamathela, i-anti-uV, ukumelana nokushisa, ukumelana nezinga lokushisa eliphansi, ukwenyanya amanzi, ukusebenza kokufakwa kwe-insulation nezinye izinkomba zokusebenza ngokomzimba namakhemikhali zihlukile.
I-Elasticity: i-collate ithambile, imojula yokunwebeka incane, khona-ke ukuguquguquka kuba ngcono. Phakathi kwazo, imodyuli yokunwebeka ye-silicone eguquliwe incane kakhulu.
Ukuzinza kwesakhiwo samangqamuzana: Ngaphansi kwesenzo sesikhathi eside se-UV, umoya kanye nezinga lokushisa eliphezulu neliphansi, ukwakheka kwamakhemikhali ezinto ezibonakalayo kuzinzile, akugugi futhi akuqhekeki. Phakathi kwazo, i-silicone eguquliwe iyona ezinzile kakhulu.
Ukunamathela: ukunamathela okuqinile akulula ukucwecwa, lapho ukunamathela kwe-epoxy resin kunamandla kakhulu, kodwa ukuqina kwesakhiwo samakhemikhali akubi, kulula ukuguga ukuqhekeka.
Ukunengwa kwamanzi: kubonisa ikhono lekholaji lokumelana nokugeleza kwamanzi. Phakathi kwabo, ukulungiswa kwamanzi abicah abicah okuguquguqukayo kungcono.
Ukufakwa kwe-insulation: ukufakwa kwe-insulation okuhlobene nezinkomba zokuphepha komkhiqizo, izinto ezimbalwa ezingenhla zeglue ekhethekile yokugcwalisa ziyizinto ezinhle zeglue ekhethekile ye-potted zinhle.
Kusukela ekusebenzeni okuphelele okungenhla kwe-physicolic, ukusebenza kwezinto eziguquliwe ze-silicone kungcono kakhulu.
2) Vala i-adhesive
Ama-sealants avamise ukubopha amaphakeji, alungele ukwakhiwa kokunamathelayo, ngokuvamile asetshenziselwa iziphetho zocingo, izingxenye zesakhiwo segobolondo elingaqondile lokubopha umthungo nokubeka uphawu. I-dispenser yeqembu elilodwa evame ukusetshenziswa, ekamelweni lokushisa nokusabela komhwamuko womoya, ukuqina kwemvelo.
Ukunakwa okukhethekile: ezinye izitshalo zokukhiqiza izibani zisebenzisa i-glue yodonga lwamakhethini engathathi hlangothi, kune-sealant ye-elekthronikhi echwepheshile, kulula ukudiliza izinto eziyingozi, izibani zokulimala.
Izinhlobo ezithile zama-potting gels kanye nama-sealants enqubweni yejeli, zizodiliza inani elincane loketshezi lwamakhemikhali noma igesi, njengobuhlalu besibani eduze nokubola kwe-colloidal yokulimala kobuhlalu besibani kubuhlalu besibani obuyimpuphu ye-fluorescent, okuholela ekushiseni kombala. ukukhukhuleka, noma ukwephula i-chip ye-led, noma ukubola ngokusabela kwamakhemikhali epulasitiki e-PC esobala, ukulimala kwesakhiwo se-PC sento, njalonjalo. Lokhu kuyingozi engaba khona ezinhlelweni zokuhlanganisa futhi kufanele kuklanywe nomkhiqizi oqoqiwe eqondwa ngokugcwele ngezakhiwo zawo zamakhemikhali nezomzimba futhi ahlolelwe ukuqinisekiswa.
I-Sealant ekwakhiweni kwegobolondo lesibani se-seal yokubopha, ethinteke kakhulu ekunciphiseni ukushisa okubandayo, ikakhulukazi izibani ezinkulu, izinto ezihlukene zomehluko we-coefficient umehluko omkhulu, ukunwetshwa okushisayo okubandayo kudonsa njalo, kulula kakhulu ukuvela imifantu. Ngakho-ke, ikhono lokuvimbela amanzi lomklamo ongenamanzi wezinto ezibonakalayo ikakhulukazi lincike ekugcwaliseni ibhodi lesifunda.
Inqubo yokukhiqiza engangeni manzi yinde, umjikelezo ongu-1 wokuqinisa ijeli lokunisela udinga amahora angama-24, ukwakheka komkhiqizo othile kuyinkimbinkimbi kakhulu, kudinga ngisho nomjikelezo wokunisela ongu-2 kuya kwemi-3, okuholela emjikelezweni omude wokuthumela, inani elikhulu lomsebenzi wezindawo zokukhiqiza, kanye nokukhiqizwa. imvelo ingcolile. Ngemuva kokuqina kwe-colloidal, ukulungiswa komkhiqizo kunzima kakhulu.
Isakhiwo sesakhiwo sesibani esingangeni manzi asidingi ukunemba kakhulu, inqobo nje uma umklamo ugcina indawo ye-collage potted, uketshezi aluvuzi, ukusebenza kwalo okungangeni manzi kunembile kakhulu. Ngakho-ke, inqubo yokuvinjelwa kwamanzi yezinto ezibonakalayo ifaneleka kakhulu ezibanini ezincane zangaphandle, izibani zangaphakathi ezifaka umswakama. Ivamise ukusetshenziswa emikhiqizweni yemodi yomphakathi esezingeni eliphansi futhi engabizi. Okufana nebhande elithambile elikhanyayo, amalambu amancane, amalambu angcwatshwe nezinye izibani ezincane.
Sekukonke, kungakhathaliseki ukuthi isakhiwo singenawo amanzi noma impahla ayinawo amanzi, izibani zangaphandle ukuzinza komsebenzi wesikhathi eside, izidingo zezinga eliphansi lokuhluleka, umklamo owodwa ongenamanzi kunzima ukufeza ukwethembeka okuphezulu kakhulu, izingozi ezingase zibe khona ezifihliwe zokugeleza kwamanzi zisekhona.
Ngakho-ke, ukuklanywa kwezibani ze-LED zangaphandle eziphezulu, kunconywa ukusebenzisa ubuchwepheshe obungangeni manzi ngokuguquguquka, ubuchwepheshe bokuvimbela amanzi obuhlelekile kanye nobuchwepheshe bokuvimbela amanzi ukuze kuhlanganiswe izinzuzo zesikhathi eside nesifushane, ukuqinisekisa ukuzinza kwesikhathi eside komsebenzi wesifunda se-LED. . Uma umklamo impahla manzi, kungenziwa wanezela ukuze ukuphefumula ukuqeda ingcindezi negative. Futhi ukwakheka okungangeni manzi, kungabuye kucabangele ukwandisa ibhodwe, ukuvikela okungangeni manzi kabili, ukuthuthukisa ukuzinza kokusetshenziswa kwesikhathi eside kwezibani zangaphandle, ukunciphisa izinga lokuhluleka komswakama.
