1. Chii chinonzi UV Curing Technology?
UV Kurapa Tekinoroji tekinoroji yekurapa nekukasira kana kuomesa mumasekonzi umo ultraviolet inoiswa kune maresheni akadai semajasi, anonamira, yekumaka inki uye mafoto-resist, nezvimwewo, kukonzera photopolymerization. Ne olymerization reaction nzira nekupisa-kuomesa kana kusanganisa zvinwiwa zviviri, zvinowanzotora pakati pemasekondi mashoma kusvika maawa akati wandei kuomesa resin.
Anenge makore 40 apfuura, tekinoroji iyi yakatanga kushandiswa kuomesa kudhinda paplywood yezvinhu zvekuvaka. Kubva ipapo, yakashandiswa mune chaiyo minda.
Munguva pfupi yapfuura, kuita kweUV inorapika resin kwakavandudza zvakanyanya. Zvakare, mhando dzakasiyana dzeUV dzinorapika resin dzave kuwanikwa uye kushandiswa kwavo pamwe nemusika kuri kukura nekukurumidza, sezvo zvine pundutso maererano nekuchengetedza simba / nzvimbo, kuderedza tsvina, uye kuwana chibereko chepamusoro uye kurapwa kwakaderera.
Pamusoro pezvo, UV yakakodzerawo kuumbwa kwemaziso sezvo iine simba rakanyanya density uye inogona kutarisa pane mashoma madhayamita enzvimbo, ayo anobatsira kuwana zviri nyore zvigadzirwa zvakaumbwa.
Chaizvoizvo, kuve isiri-inonyungudika mumiririri, UV inorapika resin haina chero organic solvent inokonzera yakaipa mhedzisiro (semuenzaniso, kusvibiswa kwemhepo) pane zvakatipoteredza. Uyezve, sezvo simba rinodiwa pakurapa riri shoma uye kubuda kwecarbon dioxide kwakadzikira, tekinoroji iyi inoderedza kuremerwa kwezvakatipoteredza.
2. Zvimiro zveUV Kurapa
1. Kurapa kuita kunoitika mumasekonzi
Mukuita kwekurapa, monomer (Liquid) inoshanduka kuita polymer (Solid) mukati memasekondi mashoma.
2. Kunyatsoteerera kwezvakatipoteredza
Sezvo zvinhu zvese zvichinyatso rapwa ne solvent-isina photopolymerization, inoshanda chaizvo kuzadzisa zvinodiwa zvemitemo ine chekuita nenharaunda uye maodha akadai sePRTR (Pollutant Release and Transfer Register) Law kana ISO 14000.
3. Yakakwana kune process automation
UV inorapika zvinhu haipore kunze kwekunge yakavhenekerwa nechiedza, uye kusiyana nezvinhu zvinorapika zvinopisa, haiporeswe zvishoma nezvishoma panguva yekuchengetedzwa. Nekudaro, iyo poto-hupenyu ipfupi zvakakwana kuti ishandiswe mune otomatiki maitiro.
4. Kurapa kwakaderera-kupisa kunogoneka
Sezvo nguva yekugadzira ipfupi, zvinokwanisika kudzora kukwira kwekushisa kwechinhu chinotarirwa. Ichi ndicho chimwe chezvikonzero nei ichishandiswa mune dzakawanda kupisa-sensitive electronics.
5. Inokodzera mhando yega yega yekushandisa sezvo zvakasiyana siyana zvekushandisa zviripo
Zvinhu izvi zvine kuoma kwepamusoro uye kupenya. Uyezve, iwo anowanikwa mune akawanda mavara, uye nekudaro anogona kushandiswa kune akasiyana zvinangwa.
3. Nheyo yeUV Kurapa Technology
Maitiro ekushandura monomer (mvura) kuita polymer (yakasimba) nerubatsiro rweUV inodaidzwa kuti UV Kurapa E uye iyo yakagadzirwa organic zvinhu inorapwa inonzi UV Inorapika Resin E.
UV Inorapika Resin musanganiswa une:
(a) monomer, (b) oligomer, (c) photopolymerization initiator uye (d) zvakasiyana-siyana zvinowedzera (stabilizers, fillers, pigments, etc.).
(a) Monomer chinhu chakasimwa chinoitwa polymerized uye chinoshandurwa kuita mamorekuru epolymer kuita plastiki. (b) Oligomer chinhu chakatoita kune monomers. Nenzira imwecheteyo semonomer, oligomer inogadzirwa nepolymer uye inoshandurwa kuita mamorekuru makuru kuita plastiki. Monomer kana oligomer haiite nyore kuita polymerization reaction, saka ivo vanosanganiswa neye photopolymerization initiator kuti vatange kuita. (c) Iyo photopolymerization initiator inofara nekutorwa kwechiedza uye kana maitiro, akadai seanotevera, aitika:
(b) (1) Cleavage, (2) Hydrogen abstraction, uye (3) Electron transfer.
(c) Nekuita uku, zvinhu zvakaita se radical molecules, hydrogen ions, nezvimwewo, izvo zvinotanga kuita zvinogadzirwa. Iwo anogadzirwa radical mamorekuru, hydrogen ions, nezvimwewo, kurwisa oligomer kana monomer mamorekuru, uye matatu-dimensional polymerization kana crosslinking reaction inoitika. Nekuda kwekuita uku, kana mamorekuru ane saizi yakakura kupfuura saizi yakatsanangurwa akaumbwa, mamorekuru akafumurwa kuUV anoshanduka kubva kumvura kuenda kune yakasimba. (d) Zvimwe zvinowedzera (stabilizer, filler, pigment, nezvimwewo) zvinowedzerwa kune UV inorapika resin kuumbwa sezvinodiwa,
(d) ipe kugadzikana, simba, nezvimwe.
(e) Liquid-state UV inorapika resin, iyo inoyerera zvakasununguka, inowanzo rapwa nematanho anotevera:
(f) (1) Photopolymerization inotanga kutora UV.
(g) (2) Aya mafotopolymerization ekutanga atora UV anofara.
(h) (3) Activated photopolymerization initiators vanoita ne resin zvikamu zvakadai se oligomer, monomer, nezvimwewo, kuburikidza nekuora.
(i) (4) Uyezve, zvigadzirwa izvi zvinopindirana nezvikamu zve resin uye ketani inoenderera mberi. Zvadaro, matatu-dimensional crosslinking reaction inoenderera mberi, huremu hwema molecular hunowedzera uye resin inorapwa.
(j) 4. Chii chinonzi UV?
(k) UV inonzi electromagnetic wave ye100 kusvika 380nm wavelength, yakareba kupfuura iya yeX-rays asi ipfupi pane iya yemwaranzi inooneka.
(l) UV yakakamurwa kuita zvikamu zvitatu zvinoratidzwa pazasi zvichienderana newavelength yayo:
(m) UV-A (315-380nm)
(n) UV-B (280-315nm)
(o) UV-C (100-280nm)
(p) Kana UV ichishandiswa kurapa resin, mayunitsi anotevera anoshandiswa kuyera huwandu hwemwaranzi yeUV:
(q) - Irradiation intensity (mW/cm2)
(r) Irradiation intensity pane imwe unit nzvimbo
(s) - UV kuratidzwa (mJ/ cm2)
(t) Irradiation simba pachikamu cheyuniti uye huwandu hwakazara hwemafotoni kusvika pamusoro. Chigadzirwa cheirradiation kusimba uye nguva.
(u) - Hukama pakati pekuratidzwa kweUV uye kusimba kwekuvhenekesa
(v) E=I x T
(w) E=Kuratidzwa kweUV (mJ/cm2)
(x) I =Kusimba (mW/cm2)
(y) T=Nguva yekuvheneka (s)
(z) Sezvo kuratidzwa kweUV kunodiwa pakurapa kunoenderana nechinhu, nguva inodiwa yekuvhenekesa inogona kuwanikwa nekushandisa fomula iri pamusoro kana iwe uchiziva kusimba kwe UV irradiation.
