I-LED Ultraviolet Irradiation Polyolefin Crosslinking Equipment

The new LED ultraviolet irradiation polyolefin cross-linking equipment adopts the new technology. The power consumption of the LED lamp is 70% lower than that of the old irradiation, and the cross-linking speed is more than twice of the original. The new product solves the shortcomings of the thick insulation, impervious to radiation and slow speed. Less land occupation, more reasonable design, eliminating the steam cross-linking process, greatly improving production efficiency. Significant cost and time savings based on customer response.

The process of UV irradiation polyolefin crosslinking equipment uses ultraviolet light as a radiation source, and the mixed photo-crosslinked polyolefin compound is extrusion-molded on the conductive core, and then immediately enters into a special irradiation equipment. The molten state is crosslinked by light. The light-crosslinked polyolefin insulated wire and cable products can be obtained by the light-radiated cross-linked insulated core after cooling treatment at different temperatures and other subsequent processing.

The UV irradiation polyolefin crosslinking equipment only needs to be slightly modified in the original ordinary extrusion production line, and the upper traction, radiation box, electric control cabinet, etc., which occupy a small area,  can be installed to meet the operational requirements and produce UV irradiated crosslinked polyethylene wire and cable products.

Idivayisi ye-Ultraviolet LED ingumthombo wemisebe ye-ultraviolet ethuthuke kakhulu emhlabeni, enamandla amakhulu kakhulu (cishe ama-30%), ukukhetha okuphezulu okusebenzayo kwe-wavelength (umkhawulokudonsa wamandla ayingxenye ye-wavelength 5nm), impilo yesevisi ephezulu kakhulu (amahora angu-30,000), ukushisa okuphansi kwe-infrared isizukulwane, asikho isizukulwane se-ozone, esilungele kakhulu ukuphulukiswa okuxhumanisa ukuphambana kwe-polyolefin exhumene nesiphambano nezinye izinto.

 Umthombo we-UV LED usebenzisa isakhiwo selensi enelungelo lobunikazi ukuze ukhanyise ubuso bekhebula ngokulinganayo nangokulinganayo. Idizayini ye-substrate yenziwa ngenhlanganisela ye-Fluent software simulation fluid kanye nokuhlolwa kwezinga lokushisa kwe-junction ye-LED, futhi ibhodi lesifunda le-LED liklanywe ngenhlanganisela ye-aluminium nitride ceramic nesisekelo sethusi esisebenza kangcono ngokukhipha ukushisa, futhi inokukhipha ukushisa okuphumelelayo. uhlelo.

 Umthombo we-UV LED usebenzisa umthombo wamandla wenethiwekhi osabalalisiwe ukushayela i-UV LED. Amandla kagesi okushayela ahlanganiswe ohlelweni lwe-vacuum potting ukuqinisekisa ukwethembeka kokunikezwa kwamandla. Ngesikhathi esifanayo, ukwakheka kwamandla okushayela kuthatha isakhiwo esincane futhi eside, futhi umthombo wokukhanya we-LED wohlobo olude usebenzisa imodi yokufaka i-back-to-back yesekethe ye-LED ukuze unciphise ubude bentambo. Bona ukuthi umthombo wokukhanya uvuliwe, uvaliwe, futhi ufiphalisa imisebenzi.

Imishini yokuxhumanisa i-UV LED irradiation polyolefin cross-linking yamukela isakhiwo somhubhe oyisiyingi, futhi ifakwe umthombo wokukhanya we-ultraviolet LED ukwenza umhubhe wokukhanyisa isifunda esimaphakathi, futhi amandla edivayisi angasethwa ngaphandle kwesinyathelo ebangeni le-10. ku-100%.

Uma kuqhathaniswa nemishini yokuxhumanisa isibani se-mercury yendabuko yohlobo lwe-irradiation (i-UVI/UVII eqhutshwa yi-transformer yendabuko kanye ne-UVE-I eqhutshwa ngamandla kagesi), ukuxhumanisa i-electron accelerator cross-linking, kanye ne-silane cross-linking, inalezi zinzuzo ezilandelayo:

1 Ukusetshenziswa Okuphansi Amandla

Amandla afakiwe e-UV LED irradiation polyolefin cross-linking alingana ne-1/4 yezinto zokuqala zokushisisa i-ultraviolet, i-1/30 ye-electron accelerator, amanzi noma umhwamuko wamanzi udinga ukufudumeza isikhathi eside, futhi ukusetshenziswa kwamandla okushisa kwamanzi kukhulu kakhulu. phezulu.

2 Isikhathi esifushane

I-cross-linking isebenzisa indlela yokuxhumanisa i-inthanethi ye-extrusion cross-linking ukuze kuncishiswe inqubo elandelayo yokuhlanganisa ukuxhumanisa, uma kuqhathaniswa nesikhathi esidingekayo sokuxhumanisa i-silene ebilisiwe noma esizwa ngesitimu kanye nokucutshungulwa kwe-electron beam irradiation, ukonga isikhathi sokukhiqiza izintambo. , ikakhulukazi izimo eziphuthumayo Ukuqedwa komsebenzi, izinzuzo zibalulekile.

3 Izindleko Eziphansi

Uma kuqhathaniswa nokuxhumanisa amanzi afudumele nokucutshungulwa kokusebenza kwemisebe ye-electron, intengo yekhebula lomsebe we-ultraviolet iphansi, futhi izinqubo eziningi eziyinkimbinkimbi ziyehliswa enqubweni yokukhiqiza, njengezindleko zokuthutha zezintambo eziqedwe kancane kanye nezindleko zomqhubi ezihambisanayo.

4 Ayikho i-Ozone

Ukukhethwa kwe-wavelength ephezulu kakhulu, kukhipha kuphela amaza awusizo, akukho misebe ye-infrared, inani eliphansi le-calorific; inani eliphansi kakhulu lemisebe ebonakalayo, akukho ukungcoliswa kokukhanya; akukho misebe ye-ultraviolet yamaza amafushane, akukho monakalo emzimbeni womuntu, ukukhishwa kwe-ozone okuyi-zero. Asikho isidingo sokupholisa ukugeleza komoya kwefeni enamandla amakhulu, asikho isidingo sepayipi elikhipha ukushisa eliyinkimbinkimbi ikakhulukazi ne-ozone-dicharging, sidinga kuphela ukuxhuma ipayipi lokukhipha umoya elinobubanzi obuncane kanye nesiphephetha-moya esingu-2kW ukuze singafaki intuthu ephansi yamangqamuzana ekhiqizwe ngesikhathi sokufakwa kwe-insulation. . Vimbela imiphumela ye-irradiation elula.

5 Usayizi Omncane, Kulula Ukuwufaka

Vele ungeze ibanga elingama-2m phakathi komugqa wokuqala wokukhiqiza isikhunta se-extruder kanye nethangi lamanzi afudumele, bese ubeka umshini wokukhipha imisebe endaweni engamamitha angu-2.5~3 ububanzi, noma encane. I-chiller ingabekwa endaweni.

6 Kulula Ukusebenza

Ukuvula nokuvala umhubhe othule, kulula ukuhlanza nokugqoka umkhondo, kulula ukusebenza, akukho nqubo eyinkimbinkimbi, ingaqedwa ngu-opharetha we-extruder.

7 Ukuphila Okude Nezindleko Zokulungisa Eziphansi

Ukuphila kwamadivayisi e-LED cishe amahora angu-30,000, futhi impilo yezinye izinto zikagesi neze-elekthronikhi ayikho ngaphansi kwempilo evamile yemikhiqizo kagesi neye-elekthronikhi, ngaphandle kokugcinwa njalo. Ukugcinwa okuvamile ukugcina i-lens optical ihlanzekile, izinto ezisetshenziswayo ziyi-industrial wipes kanye ne-soot cleaners, engenziwa ngu-opharetha. Izinto ezisetshenziswayo zendabuko zokuthela imisebe amalambu e-UV nezibonisi, ezidinga ukushintshwa ngesikhathi esifushane. Iyunithi ye-electronic ray irradiation nayo iyadingeka ukuze kugcinwe ithimba lokulungisa.

8 Okuhlaza

I-Ambient Air Quality Standard (GB3095-2012) ku-Industrial Hygiene Standard ibeka ukuthi izinga lokuphepha le-ozone ngu-0.15ppm. Imishini yokuxhumanisa i-UVLED UV ngeke ikhiqize i-ozone, kuyilapho izibani zesibani ze-mercury zendabuko zizokhiqiza inani elikhulu le-ozone. I-ozone igesi eyingozi.
