一.绷网
One. The bandage net
绷网步骤:网框清理--水平检校--涂底层胶--拉网--测张力--涂粘胶--下网、封边--储存
Stretching steps: net frame cleaning - level calibration - coated adhesive - Net - measurement network, edge tension -- adhesive - - storage
作业说明:
Job description:
1.因网框重复使用,网框四周有残存之粘胶、网纱等杂物,必须清除干净,以免影响网纱与网框之粘合力。
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.将网框放置于平台(需水平)检查网框是否变形,如有变形则需进行整平处理。
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,未变形网框与网纱接着面溥而均匀的涂一层不加硬化剂的胶水以便增强拉网后网纱与网框粘合力。
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.待第一次涂胶约10分钟后,将网框放置于拉网台,并调整好相对之位置及高度
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.选择网目,松开四周夹嘴,将网纱平铺在框上,然后将网纱均匀夹进夹嘴里,不能有起皱,注意四角要有较松余网纱,夹嘴一定需锁紧,夹子与夹子之间不能有间隙(自动升架、手动拉网为例)。
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.绷网:第一次张力26,静置5分钟张力为24;第二次张力28,静置5分钟张力26;第三次张力32,静置5分钟张力为30;第四次校正5点张力32,静置20分钟后上胶张力30;15分钟胶固化下网张力28,静置72小时后方可制作网版(以一米×一米全自动生产线使用网版为例)。纵向横向同步拉开,一直拉到所需张力时则刷胶,常用网网纱张力为(100T、110T、120T均为30±2牛顿)(77T、51T均为35±2牛顿)(24T为50±2牛顿)
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.将已调好的胶水用小毛刷均匀地刷在网框与网纱接着面上方,不可将胶水掉进网版中间部位,待胶8分钟干燥后,可用刮刀胶在涂胶面将未完全贴合之地方压紧贴合约10分钟左右胶水彻底干燥后(应采用开放式吹风加强干燥)才可下网。
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.使用裁纸刀去除网版四周多余网纱,并在网版边框注明,日期,网目及下网时张力(以便观察张力变化)为了防止洗网水(防白水)的渗入,在网框的内角用红胶水密封,然后用防水胶带封在网框与网纱接着面上方,同样防止药水的渗入。
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.晒网
Two. Bask net
1.洗网:用磨网膏去油脂(新网),鬼影膏去图形(旧网),除浆粉去网浆、蓝油,用防白水洗杂物,用清洁剂冲洗网,最后用高压水枪冲洗干净,最后用纯净水清洗干净。
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.烘干:--烤箱设定温度应小于48摄氏度。
2. drying: - the setting temperature of the oven should be less than 48 degrees Celsius.
3.使用贴水菲林方法:洗干净的网再用纯净水清洗一次。按工程菲林拼片图形加大20%左右选取水菲林,用三角尺压住水菲林一端在网上,随即用三角尺慢慢往上刮平,再用胶刮刀轻压刮平,毛巾擦多余水份烘干。
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.使用感光胶(网浆):烘干网板再上感光胶,使用刮盒,将刮到网上,其中丝印绿油需上浆三次,(约每隔10分钟以上一次)丝印其他的抗腐蚀油墨则二次,丝印可剥离胶(兰胶〕先上50微米水菲林撕去胶片,再上2次网浆,每次刮三次,上浆完成后烘干。
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.网纱的选用情况一般线路包含字符油墨的丝印、及抗腐蚀油墨(绿油、底油、面油)用120T、100T、110T网纱,碳浆(碳油)51T,丝印可剥离油墨(蓝胶〕24T丝印感光线路及热固化油墨用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.菲林的选用线路用18K水菲林(不用感光胶用感光胶上网容易不均匀会产生:如毛边(狗牙)等问题),其他抗蚀油墨(绿油、底油、面油)选用感光胶(网浆),碳浆(碳油)选用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.用所需工程图形菲林贴在网板选取的位置,放置于爆光机上进行爆光,时间的选用(3000W聚光灯),线路一般在60-80秒、绿油在80-100秒、底面字符油40-60秒、碳油、兰胶350-400秒
7.用所需工程图形菲林贴在网板选取的位置,放置于爆光机上进行爆光,时间的选用(3000W聚光灯),线路一般在60-80秒、绿油在80-100秒、底面字符油40-60秒、碳油、兰胶350-400秒
8.加压水冲网,干燥。
8. pressurized water punching net, dry.
9.网板制成后使用封网胶(蓝油)将丝网上没有被菲林或感光胶覆盖的地方,用丝印刮刀刮上封网胶,干燥。
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.检查、修网、写上完成日期及各相对应编号并记录存档、储存。
10. check, repair the net, write the completion date and each relative number and record the archiving and storage.
三.储存
Three. Storage
储存时一般采用垂直存放,可自制或购买网框架,需存放在与丝印环境相同的环境中以防变形,同时在丝印前需对丝网的张力进行测试,并可用照相底片对图形进行检验。
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.
