KUYESA NJIRA-KUDULA TAPE KUYESA-ASTM D3359-02

10. Zida ndi Zida

10.1 Chida Chodulira 9—Lezala lakuthwa, ng’amba, mpeni kapena chida china chodulira chokhala ndi ngodya yodula pakati pa 15 ndi 30° yomwe ingadulire limodzi kapena kudulako mbali imodzi.ral amacheka nthawi yomweyo. Ndikofunikira kwambiri kuti m'mphepete mwake kapena m'mphepete mwake mukhale bwino.
10.2 Zodulira - Ngati kudula kumapangidwa pamanja (mosiyana ndi makina opangira makina) chitsulo kapena chitsulo china cholimba chowongoka kapena template kuti muwonetsetse mabala owongoka.
10.3 Lamulo-Lamulo lachitsulo chotenthetsera linamaliza maphunziro awo mu 0.5 mm poyeza mabala a munthu aliyense.
10.4 Tepi, monga tafotokozera mu 5.3.
10.5 Rubber Eraser, kumapeto kwa pensulo.
10.6 Kuwala, monga tafotokozera mu 5.5.
10.7 Magnifying Glass—Chikukulitsira chowala chogwiritsidwa ntchito pocheka munthu payekha ndikuwunika malo oyesera.

11. Mayesero a Zitsanzo

11.1 Zitsanzo zoyesera zidzakhala monga momwe zafotokozedwera mu Gawo 6. Tiyenera kuzindikira, komabe, kuti multitip cutters10 amapereka zotsatira zabwino kokha pa malo oyesera mokwanira kuti mbali zonse zodula zigwirizane ndi gawo lapansi pamlingo womwewo. Yang'anani kutsetsereka ndi m'mphepete mowongoka monga lamulo lachitsulo chokhazikika.

12. Ndondomeko

12.1 Ngati pangafunike kapena ngati mwagwirizana, yesani zitsanzozo kukayezetsa koyambirira musanayese kuyesa tepi (onani Zolemba 3). Mukaumitsa kapena kuyesa zokutira, yeserani tepi kutentha kutentha monga momwe tafotokozera mu Specification D 3924, pokhapokha ngati kutentha kwa D 3924 kumafunika kapena kuvomerezedwa.
12.1.1 Kwa zitsanzo zomwe zamizidwa: Pambuyo pa kumizidwa, yeretsani ndi kupukuta pamwamba ndi zosungunulira zoyenera zomwe sizingawononge kukhulupirika kwa zokutira. Kenaka yimitsani kapena konzekerani pamwamba, kapena zonse ziwiri, monga momwe mwagwirizana pakati pa wogula ndi wogulitsa.
12.2 Sankhani malo opanda zilema ndi zolakwika zazing'ono, ikani pamalo olimba, ndi pansi pa chokulitsa chowunikira, panganirallel cuts motere:
12.2.1 Pa zokutira zomwe zimakhala ndi filimu yowuma mpaka kuphatikizirapo 2.0 mils (50 μm) danga lodula 1 mm motalikirana ndi kupanga mabala khumi ndi limodzi pokhapokha mutagwirizana.
12.2.2 Pa zokutira zomwe zimakhala ndi filimu yowuma pakati pa 2.0 mils (50 μm) ndi 5 mils (125 μm), patulani mabala 2 mm motalikirana ndikupanga mabala asanu ndi limodzi. Kwa makanema okhuthala kuposa 5 mils gwiritsani ntchito Njira Yoyesera A.11
12.2.3 Pangani mabala onse pafupifupi 20 mm (3⁄4 in.) kutalika. Dulani filimuyo ku gawo lapansi ndikusuntha kokhazikika pogwiritsa ntchito kukanikiza kokwanira pa chida chodulira kuti m'mphepete mwake mufikire gawo lapansi. Popanga mabala amodzi motsatizana mothandizidwa ndi kalozera, ikani kalozera pamalo osadulidwa.
12.3 Pambuyo popanga mabala ofunikira tsukani filimuyo mopepuka ndi burashi yofewa kapena minofu kuti muchotse ma flakes otsekedwa kapena nthiti za zokutira.
12.4 Yang'anani m'mphepete mwake ndipo, ngati kuli kofunikira, chotsani madontho athyathyathya kapena mawaya potulutsa pang'ono pamwala wabwino wamafuta. Pangani manambala owonjezera pa 90 ° mpaka ndikukhazikika pamadula oyambira.
12.5 Tsukani malowo monga kale ndikuyang'ana mayendedwe a kuwala kwa gawo lapansi. Ngati chitsulo sichinafike pangani gululi ina kumalo ena.
12.6 Chotsani mizere iwiri yathunthu ya tepi ndikutaya. Chotsani utali wowonjezera pamlingo wokhazikika (ndiko kuti, osagwedezeka) ndikudula chidutswa cha 75 mm (3 in.) utali.
12.7 Ikani pakati pa tepi pamwamba pa gululi ndi m'dera la gridi yosalala bwino ndi chala. Kuonetsetsa bwino kukhudzana ndi filimu pakani tepi mwamphamvu ndi chofufutira pa mapeto a pensulo. The mtundu pansi pa tepi ndi chizindikiro chothandiza cha pamene kukhudzana kwabwino kwapangidwa.
12.8 Mkati mwa 90 6 30 s pogwiritsira ntchito, chotsani tepiyo pogwira malekezero aulere ndi mofulumira (osagwedezeka) kubwereranso pawokha pafupi ndi ngodya ya 180 ° momwe mungathere.
12.9 Yang'anani malo agululi kuti muchotse zokutira ku gawo lapansi kapena zokutira zam'mbuyomu pogwiritsa ntchito chokulitsa chowunikira. Vomerezani kumamatira molingana ndi sikelo yotsatiridwa yomwe ikuwonetsedwa mkuyu 1: 5B Mphepete mwa mabala ndi yosalala; palibe mabwalo onse a latisi omwe atsekedwa.
4B Ma flakes ang'onoang'ono a zokutira amachotsedwa pamipata; ochepera 5 % a madera omwe akhudzidwa.
3B Ma flakes ang'onoang'ono a zokutira amatsekedwa m'mphepete ndi m'mphepete mwa mabala. Malo omwe akhudzidwa ndi 5 mpaka 15% ya lattice.
2B Chophimbacho chang'ambika m'mphepete ndi mbali zina za mabwalo. Malo omwe akhudzidwa ndi 15 mpaka 35 % ya lattice.
1B Chophimbacho chaphwanyidwa m'mphepete mwa mabala m'maliboni akuluakulu ndipo mabwalo onse atsekedwa. Dera lomwe lakhudzidwa ndi 35 mpaka 65% ya lattice.
0B Kuphulika ndi kuthamangitsidwa koyipa kuposa Giredi 1.
12.10 Bwerezani mayeso m'malo ena awiri pagawo lililonse loyesa.

13. Lipoti

13.1 Nenani kuchuluka kwa mayeso, tanthauzo lake ndi mtundu wake, ndi machitidwe opaka, pomwe kulephera kudachitika, ndiye kuti, pakati pa malaya oyamba ndi gawo lapansi, pakati pa malaya oyamba ndi achiwiri,
etc.
13.2 Nenani gawo lapansi lomwe lagwiritsidwa ntchito, mtundu wa zokutira ndi njira yochizira.
13.3 Ngati mphamvu yomatira yatsimikiziridwa molingana ndi Njira Zoyesera D 1000 kapena D 3330, nenani zotsatirazo ndi mavoti omatira. Ngati mphamvu yomatira ya tepiyo siinatsimikizidwe, nenani tepi yeniyeni yomwe imagwiritsidwa ntchito ndi wopanga.
13.4 Ngati mayeso achitika pambuyo pa kumizidwa, lipoti mikhalidwe yomiza ndi njira yokonzekera zitsanzo.

14. Kulondola ndi kukondera

14.1 Pamaziko a mayeso awiri a m'ma labotale a njira yoyeserayi m'modzi mwa omwe ogwira ntchito m'ma labotale asanu ndi limodzi adayesa kuyeza komatira pamapanelo atatu chilichonse mwa zokutira zitatu zomwe zimaphimba kumatira kosiyanasiyana ndipo ena ogwira ntchito m'ma labotale asanu ndi limodzi adapanga miyeso itatu pamapanelo awiri. Iliyonse mwa zokutira zinayi zosiyana zomwe zidayikidwa pazovala zina ziwiri, zopatuka zomwe zidaphatikizidwa mkati ndi pakati pa ma laboratories zidapezeka kuti ndi 0.37 ndi 0.7. Kutengera zopatuka izi, njira zotsatirazi ziyenera kugwiritsidwa ntchito poweruza kuvomerezedwa kwa zotsatira pamlingo wodalirika wa 95 %:
14.1.1 Kubwerezabwereza-Kuperekedwa kumamatira kumakhala kofanana pamtunda waukulu, zotsatira zopezedwa ndi wogwiritsa ntchito yemweyo ziyenera kuganiziridwa ngati zokayikira ngati zimasiyana ndi mayunitsi oposa amodzi pamiyeso iwiri.
14.1.2 Kuchulukirachulukira—Zotsatira ziwiri, chilichonse chotengera kubwereza kapena kubwereza katatu, zopezedwa ndi ogwiritsa ntchito osiyanasiyana ziyenera kuganiziridwa kuti ndi zokayikitsa ngati zikusiyana ndi mayunitsi opitilira awiri.
14.2 Tsankho silingakhazikitsidwe panjira zoyesera izi.
