UV CURING Technology

1. Kodi UV Curing Technology ndi chiyani?

UV Kuchiritsa Technology ndi ukadaulo wochiritsa kapena kuyanika pompopompo m'masekondi momwe ultraviolet imayikidwa pazitsulo monga zokutira, zomatira, inki yolembera ndi zokanira zithunzi, ndi zina zotero, kuyambitsa photopolymerization. Ndi njira za olymerization reaction poyanika kutentha kapena kusakaniza zakumwa ziwiri, nthawi zambiri zimatenga pakati pa masekondi angapo mpaka maola angapo kuti ziume utomoni.

Pafupifupi zaka 40 zapitazo, luso limeneli linayamba kugwiritsidwa ntchito poyanika makina osindikizira a plywood popangira zomangira. Kuyambira pamenepo, wakhala akugwiritsidwa ntchito m'madera enaake.

Posachedwapa, ntchito ya utomoni wochiritsira wa UV yapita patsogolo kwambiri. Kuphatikiza apo, mitundu yosiyanasiyana ya ma resin ochiritsira a UV tsopano ikupezeka ndipo kugwiritsidwa ntchito kwawo komanso msika ukukula mwachangu, chifukwa ndizothandiza pakupulumutsa mphamvu / malo, kuchepetsa zinyalala, ndikukwaniritsa zokolola zambiri komanso chithandizo chotsika kwambiri.

Kuphatikiza apo, UV ndiyoyeneranso kuumbidwa ndi kuwala chifukwa imakhala ndi mphamvu zambiri ndipo imatha kuyang'ana ma diameter ang'onoang'ono, omwe amathandizira kupeza zinthu zopangidwa mwaluso kwambiri.

Kwenikweni, pokhala chinthu chosasungunuka, utomoni wochizira wa UV ulibe zosungunulira zilizonse zomwe zimayambitsa mavuto (mwachitsanzo, kuipitsidwa kwa mpweya) pa chilengedwe. Komanso, popeza mphamvu yofunikira pochiritsa ndi yochepa komanso mpweya woipa wa carbon dioxide ndi wochepa, lusoli limachepetsa mphamvu ya chilengedwe.

2. Makhalidwe a UV Kuchiritsa

1. Kuchiritsa kumachitika mumasekondi

Pochiritsa, monomer (Liquid) imasintha kukhala polima (Yolimba) mkati mwa masekondi angapo.

2. Kusamala kwapadera kwa chilengedwe

Popeza kuti zinthu zonsezo zimachiritsidwa ndi photopolymerization yopanda zosungunulira, ndizothandiza kwambiri kukwaniritsa zofunikira zamalamulo okhudzana ndi chilengedwe monga PRTR (Pollutant Release and Transfer Register) Law kapena ISO 14000.

3. Wangwiro kwa ndondomeko zochita zokha

Zinthu zochiritsira za UV sizichiritsa pokhapokha zitakhala ndi kuwala, ndipo mosiyana ndi zida zochiritsira kutentha, sizichira pang'onopang'ono pozisunga. Chifukwa chake, moyo wake wamphika ndi wamfupi mokwanira kuti ugwiritsidwe ntchito popanga makina.

4. Chithandizo chochepa cha kutentha ndi kotheka

Popeza nthawi yokonza ndi yochepa, ndizotheka kulamulira kukwera kwa kutentha kwa chinthu chomwe mukufuna. Ichi ndi chimodzi mwazifukwa zomwe zimagwiritsidwa ntchito pamagetsi ambiri osamva kutentha.

5. Yoyenera pamtundu uliwonse wa ntchito popeza zipangizo zosiyanasiyana zilipo

Zidazi zimakhala ndi kuuma kwapamwamba kwambiri komanso gloss. Kuphatikiza apo, amapezeka mumitundu yambiri, chifukwa chake amatha kugwiritsidwa ntchito pazinthu zosiyanasiyana.

3. Mfundo ya UV Kuchiritsa Technology

Njira yosinthira monoma (zamadzimadzi) kukhala polima (yolimba) mothandizidwa ndi UV imatchedwa UV Kuchiritsa E ndipo zinthu zopangidwa ndi organic zomwe ziyenera kuchiritsidwa zimatchedwa UV Curable Resin E.

UV Curable Resin ndi gulu lomwe lili ndi:

(a) monomer, (b) oligomer, (c) photopolymerization initiator ndi (d) zosiyanasiyana zowonjezera (stabilizers, fillers, pigments, etc.).

(a) Monomer ndi zinthu zakuthupi zomwe zimapangidwa ndi polymer ndikusinthidwa kukhala mamolekyulu akulu a polima kupanga pulasitiki. (b) Oligomer ndi zinthu zomwe zakhala zikuchita kale kwa ma monomers. Mofanana ndi monomer, oligomer imapangidwa ndi ma polima ndikusandulika kukhala mamolekyu akuluakulu kupanga pulasitiki. Monomer kapena oligomer samapanga ma polymerization mosavuta, chifukwa chake amaphatikizidwa ndi choyambitsa cha photopolymerization kuti ayambe kuchitapo kanthu. (c) Woyambitsa photopolymerization amasangalala ndi kuyamwa kwa kuwala komanso pamene zochita, monga izi, zikuchitika:

(b) (1) Cleavage, (2) Hydrogen abstraction, ndi (3) Electron transfer.

(c) Pochita izi, zinthu monga mamolekyu akuluakulu, ma hydrogen ions, ndi zina zotere, zomwe zimayambitsa zomwe zimachitika zimapangidwa. The kwaiye mamolekyulu kwambiri, ayoni haidrojeni, etc., kuukira oligomer kapena monoma mamolekyu, ndi mbali zitatu polymerization kapena crosslinking anachita zimachitika. Chifukwa cha izi, ngati mamolekyu okhala ndi kukula kwakukulu kuposa kukula kwake apangidwa, mamolekyu omwe amawonekera ku UV amasintha kuchoka kumadzi kukhala olimba. (d) Zowonjezera zosiyanasiyana (stabilizer, filler, pigment, etc.) zimawonjezedwa pakupanga utomoni wochiritsira wa UV ngati pakufunika, kuti

(d) ipatseni bata, mphamvu, ndi zina.

(e) Utoto wamadzimadzi amtundu wa UV, womwe umayenda momasuka, nthawi zambiri umachiritsidwa ndi izi:

(f) (1) Oyambitsa Photopolymerization amatenga UV.

(g) (2) Oyambitsa ma photopolymerization awa omwe atenga UV amasangalala.

(h) (3) Oyambitsa photopolymerization oyambitsa amachitira ndi zigawo za utomoni monga oligomer, monomer, etc., kupyolera mu kuwonongeka.

(i) (4) Kupitilira apo, zinthuzi zimachita ndi zigawo za utomoni ndikuchitapo kanthu kwa unyolo. Kenako, mawonekedwe amitundu itatu amapitilira, kulemera kwa maselo kumawonjezeka ndipo utomoni umachiritsidwa.

(j) 4. Kodi UV ndi chiyani?

(k) UV ndi mafunde a electromagnetic wa 100 mpaka 380nm wavelength, wautali kuposa wa X-ray koma wamfupi kuposa wa kuwala kowoneka.

(l) UV imagawidwa m'magulu atatu omwe ali pansipa malinga ndi kutalika kwake:

(m) UV-A (315-380nm)

(n) UV-B (280-315nm)

(o) UV-C (100-280nm)

(p) UV akagwiritsidwa ntchito kuchiza utomoni, mayunitsi otsatirawa amagwiritsidwa ntchito kuyeza kuchuluka kwa cheza cha UV:

(q) - Kuchuluka kwa waya (mW/cm2)

(r) Kuchuluka kwa waya pagawo lililonse

(s) - Kuwonekera kwa UV (mJ/cm2)

(t) Mphamvu yowunikira pagawo lililonse ndi kuchuluka kwa mafotoni kuti afike pamwamba. Mankhwala mphamvu ya walitsa ndi nthawi.

(u) - Ubale pakati pa kuwonekera kwa UV ndi mphamvu yamagetsi

(v) E=I x T

(w) E=Kuwonekera kwa UV (mJ/cm2)

(x) I =Kulimba (mW/cm2)

(y) T=Nthawi yoyatsa (s)

(z) Popeza kuti kuwala kwa UV kumafunika kuchiritsa kumadalira zinthu, nthawi yoyatsa yofunikira imatha kupezeka pogwiritsa ntchito fomula ili pamwambapa ngati mukudziwa mphamvu ya kuwala kwa UV.

(aa) 5. Chiyambi cha Zamalonda

(ab) Zida Zochiritsira za UV

(ac) Zida Zochiritsira Zothandiza ndi zotsika mtengo komanso zotsika mtengo za UV Kuchiritsa Zida pakati pazopanga zathu.

(ad) Zida Zopangira UV Zochiritsira

(ae) Zida Zopangira UV Zochiritsira zimaperekedwa ndi njira yochepera yofunikira yogwiritsira ntchito nyali ya UV, ndipo imatha kulumikizidwa ku zida zomwe zili ndi chotengera.

Chida ichi chimapangidwa ndi nyali, choyatsira, gwero lamagetsi ndi chipangizo chozizirira. Zigawo zomwe mungasankhe zitha kumangirizidwa ku choyatsira. Mitundu yosiyanasiyana ya magwero amagetsi kuchokera ku inverter yosavuta kupita ku inverters yamitundu yambiri ilipo.

Desktop UV Kuchiritsa Zida

Ichi ndi UV Curing Equipment yopangidwira kugwiritsidwa ntchito pakompyuta. Popeza kuti ndi yaying'ono, imafuna malo ochepa kuti akhazikitse ndipo ndiyopanda ndalama zambiri. Ndizoyenera kwambiri zoyeserera ndi zoyeserera.

Chida ichi chili ndi makina otsekera omangira. Nthawi iliyonse yomwe mukufuna kuyatsa imatha kukhazikitsidwa kuti ikhale yothandiza kwambiri.

Zida Zochiritsira za UV zamtundu wa Conveyor

Zida Zochiritsira za UV zamtundu wa conveyor zimaperekedwa ndi ma conveyor osiyanasiyana.

Timapanga ndi kupanga zida zosiyanasiyana kuchokera ku compact UV Curing Equipment yokhala ndi ma conveyors ophatikizika kupita ku zida zazikuluzikulu zomwe zimakhala ndi njira zosiyanasiyana zosinthira, ndipo nthawi zonse timapereka zida zoyenera kwa kasitomala.
