一.繃網
One. The bandage net
繃網步驟:網框清理--水平檢校--塗底層膠--拉網--測張力--塗粘膠--下網、封邊--儲存
Stretching steps: net frame cleaning - level calibration - coated adhesive - Net - measurement network, edge tension -- adhesive - - storage
作業說明:
Job description:
1.因網框重複使用,網框四周有殘存之粘膠、網紗等雜物,必須清除幹淨,以免影響網紗與網框之粘合力。
1. because the net frame of repeated use, the remnants of the net frame glue, gauze and other debris around, must be clean, so as not to affect the adhesion of gauze and net frame.
2.将網框放置于平台(需水平)檢查網框是否變形,如有變形則需進行整平處理。
2. the net frame is placed on the platform (level required) to check whether the net frame is deformed, and the leveling process is required if there is a deformation.
3.将清理好,未變形網框與網紗接着面溥而均勻的塗一層不加硬化劑的膠水以便增強拉網後網紗與網框粘合力。
3. will be cleaned, the undeformed gauze net frame and then the surface of thin and uniform coating layer without hardener glue so as to enhance the net after the gauze and net frame adhesive force.
4.待第一次塗膠約10分鐘後,将網框放置于拉網台,并調整好相對之位置及高度
4. after the first gumming for about 10 minutes, the net frame is placed on the netting table and the relative position and height is adjusted.
5.選擇網目,松開四周夾嘴,将網紗平鋪在框上,然後将網紗均勻夾進夾嘴裡,不能有起皺,注意四角要有較松餘網紗,夾嘴一定需鎖緊,夾子與夾子之間不能有間隙(自動升架、手動拉網為例)。
5. choose the mesh, loosen the clamp around the mouth, the gauze tile in the box, then the gauze evenly clamped in the mouth, not wrinkle, pay attention to the four angle to have a song'yu Jacobs, a clamp mouth must be locked, not between the clip and the clip has a gap (automatic or manual net frame, for example).
6.繃網:第一次張力26,靜置5分鐘張力為24;第二次張力28,靜置5分鐘張力26;第三次張力32,靜置5分鐘張力為30;第四次校正5點張力32,靜置20分鐘後上膠張力30;15分鐘膠固化下網張力28,靜置72小時後方可制作網版(以一米×一米全自動生産線使用網版為例)。縱向橫向同步拉開,一直拉到所需張力時則刷膠,常用網網紗張力為(100T、110T、120T均為30±2牛頓)(77T、51T均為35±2牛頓)(24T為50±2牛頓)
6.: the first 26 stretch mesh tension, set aside for 5 minutes second times tension tension is 24; 28, set aside for 5 minutes third times tension tension 26; 32, set aside for 5 minutes fourth times tension is 30; 5 point correction tension 32, after standing for 20 minutes 15 minutes 30 glue tension; tension curing 28, standing for 72 hours before making screen (with a m x m automatic production line using the screen as an example). The horizontal and vertical synchronization opened, has been pulled to the desired tension when the brush glue used for mesh tension (100T, 110T and 120T were 30 + 2 Newton (77T), 51T was 35 + 2 (24T Newton) 50 + 2 Newton)
7.将已調好的膠水用小毛刷均勻地刷在網框與網紗接着面上方,不可将膠水掉進網版中間部位,待膠8分鐘幹燥後,可用刮刀膠在塗膠面将未完全貼合之地方壓緊貼合約10分鐘左右膠水徹底幹燥後(應采用開放式吹風加強幹燥)才可下網。
7. will be tuned with a small brush glue evenly the gauze net frame and then the surface can not be above the middle part of the glue into the screen, 8 minutes after the glue dried, available in rubber scraper coating surface will not fully fit the local press posted 10 minutes contract thoroughly dried glue (should be open blow drying can strengthen the net).
8.使用裁紙刀去除網版四周多餘網紗,并在網版邊框注明,日期,網目及下網時張力(以便觀察張力變化)為了防止洗網水(防白水)的滲入,在網框的内角用紅膠水密封,然後用防水膠帶封在網框與網紗接着面上方,同樣防止藥水的滲入。
8. the use of paper cutting knife to remove excess around the screen mesh, and indicate the date, in the screen frame, mesh and net tension (in order to observe the change of tension) to prevent wash water network (anti white water) infiltration, sealed with red glue inside the screen frame, and then use waterproof tape in net frame with gauze then the plane, also to prevent the infiltration of liquid medicine.
二.曬網
Two. Bask net
1.洗網:用磨網膏去油脂(新網),鬼影膏去圖形(舊網),除漿粉去網漿、藍油,用防白水洗雜物,用清潔劑沖洗網,最後用高壓水槍沖洗幹淨,最後用純淨水清洗幹淨。
1., wash nets: use grease to remove grease (new net), ghosting paste to graph (old network), remove pulp, remove net oil and blue oil, wash objects with white water, rinse the net with detergent, and rinse with high pressure water gun, and clean it with pure water at last.
2.烘幹:--烤箱設定溫度應小于48攝氏度。
2. drying: - the setting temperature of the oven should be less than 48 degrees Celsius.
3.使用貼水菲林方法:洗幹淨的網再用純淨水清洗一次。按工程菲林拼片圖形加大20%左右選取水菲林,用三角尺壓住水菲林一端在網上,随即用三角尺慢慢往上刮平,再用膠刮刀輕壓刮平,毛巾擦多餘水份烘幹。
3. use the method of water patch: clean the net and clean it with pure water once. According to the engineering film, the graphics should be increased by 20% or more. The water flair should be selected. One side of the water should be pressed with a triangular ruler on the Internet. Then it will be scraped up slowly with a triangular ruler. Then it will be pressed gently by glue scraper, and the towel will wipe the excess water to dry.
4.使用感光膠(網漿):烘幹網闆再上感光膠,使用刮盒,将刮到網上,其中絲印綠油需上漿三次,(約每隔10分鐘以上一次)絲印其他的抗腐蝕油墨則二次,絲印可剝離膠(蘭膠〕先上50微米水菲林撕去膠片,再上2次網漿,每次刮三次,上漿完成後烘幹。
4. the use of photosensitive glue (net pulp): to screen drying emulsion, scraping the box, will blow to the Internet, which needs three green screen sizing, (approximately every 10 minutes more than once) corrosion screen printing ink and others two times, screen printing adhesive glue (Blue first 50 micron. Water film tear film, then 2 times net pulp, shaving three times each time, after the completion of drying and sizing.
5.網紗的選用情況一般線路包含字符油墨的絲印、及抗腐蝕油墨(綠油、底油、面油)用120T、100T、110T網紗,碳漿(碳油)51T,絲印可剝離油墨(藍膠〕24T絲印感光線路及熱固化油墨用77T。
The general line contains 5. mesh screen printing, ink characters and corrosion (green ink, bottom oil, surface oil) by 120T, 100T, 110T Jacobs, carbon paste (carbon oil) 51T, 77T (with screen printing can peel ink blue glue 24T screen printing line and heat curing photosensitive ink.
6.菲林的選用線路用18K水菲林(不用感光膠用感光膠上網容易不均勻會産生:如毛邊(狗牙)等問題),其他抗蝕油墨(綠油、底油、面油)選用感光膠(網漿),碳漿(碳油)選用50微米的水菲林
18K water film selection line 6. film (not easy to produce uneven photographic emulsion for Internet: such as flash (dog) etc), other resist ink (green, bottom oil, surface oil) using photosensitive glue (net pulp), carbon paste (carbon oil) 50 m water film selection
7.用所需工程圖形菲林貼在網闆選取的位置,放置于爆光機上進行爆光,時間的選用(3000W聚光燈),線路一般在60-80秒、綠油在80-100秒、底面字符油40-60秒、碳油、蘭膠350-400秒
7.用所需工程圖形菲林貼在網闆選取的位置,放置于爆光機上進行爆光,時間的選用(3000W聚光燈),線路一般在60-80秒、綠油在80-100秒、底面字符油40-60秒、碳油、蘭膠350-400秒
8.加壓水沖網,幹燥。
8. pressurized water punching net, dry.
9.網闆制成後使用封網膠(藍油)将絲網上沒有被菲林或感光膠覆蓋的地方,用絲印刮刀刮上封網膠,幹燥。
9. screen made use of block glue (blue oil) will not be online silk film or photographic coverage, with a screen scraper on the block glue, drying.
10.檢查、修網、寫上完成日期及各相對應編号并記錄存檔、儲存。
10. check, repair the net, write the completion date and each relative number and record the archiving and storage.
三.儲存
Three. Storage
儲存時一般采用垂直存放,可自制或購買網框架,需存放在與絲印環境相同的環境中以防變形,同時在絲印前需對絲網的張力進行測試,并可用照相底片對圖形進行檢驗。
Generally, vertical storage is used for storage, and can be made or purchased for network frame. It needs to be stored in the same environment as silk screen printing to prevent deformation. At the same time, the screen tension should be tested before screen printing, and it can be tested with photographic negatives.
