Mhando uye Phenomena Yehurombo Ultraviolet Kurapa

Kune kazhinji kwakasiyana-siyana kusimba zviitiko muUV yekurapa tekinoroji. Inonyanya kutarisana nechiitiko chakaipa ndeinotevera. Nekudaro, dzimwe nguva chikonzero chekurapa kwakashata chakazara. Mune mamwe mazwi, dzimwe nguva 2 kana kupfuura yakasimbiswa chiitiko chinoitika panguva imwe chete muchigadzirwa chimwe chete. Mhinduro chaiyo ndeye kubata vashandi vehunyanzvi vevagadziri ve UV resin, UV mercury marambi, zvigadzirwa zvechigadzirwa, uye UV kurapa michina kutanga, kana kunyatsoona chikonzero chaicho chechiitiko chekusimba. Inoshanda mhinduro. Pfungwa yekusasimba kwakashata, kunonzi kusimba, kunoreva: kutanga, hapana chimiro chakakwana chekusimba, ndiko kuti, mamiriro ekusaomesa; chechipiri, mamiriro ekunyanya kusimba, ndiko kuti, overcured. Kana chiitiko chekuomesera chikaitika, chinopiswa nekurapa, kana shanduko yekupisa inoitika nekuda kwekoriori yakakura yebhini rekurapa. Kana chiitiko chechiitiko chisingaonekwi ndechekuti resin haina kusimba zvachose, chigadzirwa chakanamira, simba rekunamira richaderedzwa zvakanyanya, kana resin mhinduro isina kusimba pamusoro pechigadzirwa. 1. Product thermal deformation heat haina zvakawanda zvinokanganisa simbi kana huni, asi iyo yakatetepa yepurasitiki yakatevedzana yefirimu kana firimu zvigadzirwa zvinonyanya kunzwira kupisa. Iwo macalorie ane hanya zvakanyanya, saka zvinogona kutaurwa kuti iyo inonyanya kukosha mubasa rekugadzirisa chigadzirwa chemafuta deformation mundima iyi. 1) Wave: Thermal deformation ndiyo yekutanga nhanho. 2) Curl: Tanga chikamu deformation. 3) Shrinkage: yakakomba deformation yenzvimbo. 4) Carbonization yekutanga nhanho: ese anoshanduka yero, dema, uye yakanyanya kupisa inopisa. 2. Kunyangwe iyo yekunamatira mhedzisiro inoratidzika kunge yapedza kurapa maitiro, iyo adhesion mhedzisiro pakati pezvinhu uye coating haina kunaka. Inogona kukweshwa nembambo kana coin zvinyoro nyoro, iyo yekurapa layer ichabviswa, uye muchinjiko-yekucheka bvunzo haugone kuyedzwa. Nharembozha, LCD kuratidza zvikamu kana mafirimu, COG/BGA uye zvimwe chip zvikamu zvinofanirwa kuve zvakasimba. 3. Swaging, Bulging) Chigadzirwa chaamai chinoda kupendwa chakafanana nepurasitiki kana rabha, iyo inonzwa zvakanyanya kuzvinhu zvinopisa. Chikamu chechinhu chaamai kana resin chinozvimba nekuda kwekudziya kana uchirapa. , Ichakonzera chiitiko chekutsva kwechinhu chaamai kana resin. Kuwedzera kwekukotama kwemukati nekunze kwakaoma, uye chiitiko chebubbles chinoonekwa mukati, kuitira kuti kutaridzika mushure mekusimba kurege kutaridzika zvakanaka. Rudzi urwu rwehuipi hunoonekwa mufirimu remaziso uye nharembozha inoratidza flat solidification. 4. Kuputika (Bubbling, Air Bubble) firimu, firimu remhando yepamusoro uye mamwe mafirimu akanyatsojeka, kunyange zvazvo kusimba uye kusungirirwa kunogona kupedzwa zvakakwana, kana ukaicherechedza nemaikorosikopu, uchaona kuti pane zvakanaka uye micro-cracks iripo. Chikonzero chacho hachisati chapedzwa, icho chiriwo chiitiko chechigadzirwa chakaipa chakaoma kugadzirisa. Isu tinotenda kuti iyi ndiyo mhedzisiro yekristaro yeresin mukugovewa kwakatwasuka mushure mekunge resin yasimbiswa. 5. Surface crack film, firimu remhando yepamusoro uye rimwe firimu chairo. Kunyange zvazvo kusimba uye kunamatira kunogona kupedzwa zvakakwana, kana iwe ukaicherechedza ne microscope, uchaona kuti pane zvakanaka uye micro-cracks. Chikonzero chacho hachisati chapedzwa, icho chiriwo chiitiko chechigadzirwa chakaipa chakaoma kugadzirisa. Isu tinotenda kuti iyi ndiyo mhedzisiro yekristaro yeresin mukugovewa kwakatwasuka mushure mekunge resin yasimbiswa. 6. Iyo phenomenon ye yellowing chiitiko chinoitika zvakanyanya kana chaoma pane transparent resin. Iwe unogona kuderedza chiitiko cheyero shanduko kubva pakuwedzera yeyero shanduko mukuumbwa kweresin kuderedza chiitiko cheyero shanduko. 7. Firimu isina-yakaoma glue inki kudhinda inowanzoshandiswa yakatetepa -firimu isiri-kuomesa zvinhu ndeiyi: polyethylene, polypropylene, polyester, polyvinyl chloride, polystyrene, polyolefin, nezvimwe. Asi mutsauko ndewekuti iyo firimu haina kubatwa. Naizvozvo, kudhindwa kwefirimu hakuomese glue kunonyanya kushandisa UV convex mamaki uye UV nyoro kudhinda. Zvakadaro, mukuita kudhinda nekugadzirisa, dambudziko rinowanzosangana nemakambani anodhinda ingi isina kukwana yeUV inki pamusoro pefirimu. The solidification ine simba guru pakutambanudza simba. Nekuwedzera kwekuporeswa kweadhesive, muchinjikwa -linked density inowedzera, chiyero che molecular mass yemuchinjikwa -linking point inova diki. Kana iyo epoxy uye polyurethane acrylics zvakabatanidzwa, kunamatira kuchawedzerwa zvikuru.
