Xabagta UV-daynta Kaduwan

Jiil cusub oo silikoon ah oo daawaynaya UV iyo epoxies ayaa si isa soo taraysa loogu isticmaalayaa codsiyada baabuurta iyo elektiroonigga ah.
Ficil kasta oo nolosha ka mid ah wuxuu ku lug leeyahay is-dhaafsi: Helitaanka faa'iido mid ka mid ah kharashka kale, si loo daboolo baahiyaha xaaladda taagan. Marka xaaladdu ay ku lug leedahay isku xidhka mugga sare, xidhidhiyaha ama xidhidhiyaha, soosaarayaashu waxay ku tiirsan yihiin xabagta daawoyinka UV sababtoo ah waxay u ogolaadaan daawaynta degdega ah iyo baahida (1 ilaa 5 sekan ka dib iftiinka iftiinka).

Ganacsi-off, si kastaba ha ahaatee, waa in koollada kuwan (acrylic, silicone iyo epoxy) waxay u baahan yihiin substrate hufan si ay si sax ah ugu xidhmaan, oo waxay aad uga qiimo badan yihiin xabagta lagu daweeyo siyaabo kale. Si kastaba ha ahaatee, warshado badan oo aan la tirin karin oo ku jira warshado badan ayaa si farxad leh u sameeyay ganacsigan dhowr iyo toban sano. Shirkado badan oo kale ayaa sidaas samayn doona mustaqbalka la filayo. Farqiga u dhexeeya, si kastaba ha ahaatee, waa in injineerada ay u badan tahay inay isticmaalaan silikoon ama epoxy UV-cure xabagta, sida mid ku salaysan akril.

"Inkasta oo aan samaynay silikoon UV-daaweeya tobankii sano ee la soo dhaafay ama wax ka badan, saddexdii sano ee la soo dhaafay waxaan ku qasbanahay inaan xoojino dadaalkeena iibinta si aan ula socono baahida suuqa," ayuu yiri Doug McKinzie, madaxweyne ku xigeenka alaabada gaarka ah ee Novagard. Xalka "Iibkayaga silikoonka UV-cure wuxuu kordhay 50 boqolkiiba dhowrkii sano ee la soo dhaafay. Tani waxay yarayn doontaa qaar, laakiin waxaan wali rajeyneynaa koboc wanaagsan dhowrka sano ee soo socda."

Isticmaalayaasha ugu waaweyn ee silikoonnada UV-cure waxaa ka mid ah OEM-yada baabuurta, iyo alaab-qeybiyeyaasha Tier 1 iyo Tier 2. Mid ka mid ah alaab-qeybiyaha Tier 2 wuxuu isticmaalaa Loctite SI 5031 sealant oo ka socda Henkel Corp. ilaa meelaha dheriga ee guryaha loogu talagalay modules-control brake-electronic iyo dareemayaasha cadaadiska taayirka. Shirkaddu sidoo kale waxay isticmaashaa Loctite SI 5039 si ay u samayso gaas silikoon ah oo UV-ku-ku-daawan oo ku wareegsan wareegga qayb kasta. Bill Brown, oo ah maamulaha injineernimada codsiyada ee Henkel, ayaa sheegay in labada alaab ay ku jiraan dheeha fluorescent si ay u caawiyaan xaqiijinta joogitaanka xabagta inta lagu jiro kormeerka ugu dambeeya.

Qayb-hoosaadkan ayaa markaa loo diraa alaab-qeybiye Tier 1 kaas oo geliya qaybo dheeraad ah oo gudaha ah oo ku xidha PCB-ga terminalka. Dabool ayaa la dulsaaraa gaaska wareega si loo abuuro shaabad deegaan ahaan dhagan kulanka ugu dambeeya.

Xabagta Epoxy UV-cure ayaa sidoo kale inta badan loo isticmaalaa codsiyada elektiroonigga ah ee baabuurta iyo macaamiisha. Mid ka mid ah sababaha ayaa ah in xabagta, sida silicones, si gaar ah loo qaabeeyey si ay u dhigmaan hirarka dhererka ilaha iftiinka LED (320 ilaa 550 nanometers), sidaas darteed wax-soo-saarayaashu waxay helayaan dhammaan faa'iidooyinka iftiinka LED-ka, sida nolosha dheer, kuleylka xaddidan iyo qaababka dabacsan. Sababta kale ayaa ah kharashka hoose ee raasumaalka ee daaweynta UV, taas oo u sahlaysa shirkadaha inay ka ganacsadaan ilaa tiknoolajiyadan.
