7. Ndondomeko

7.1 Sankhani malo opanda zilema ndi zolakwika zazing'ono. Pamayeso m'munda, onetsetsani kuti pamwamba ndi poyera komanso mowuma. Kutentha kwambiri kapena chinyezi chambiri kumatha kukhudza kumamatira kwa tepi kapena zokutira.
7.1.1 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.
7.2 Pangani mabala awiri mufilimu iliyonse pafupifupi 40 mm (1.5 in.) kutalika komwe kumadutsa pafupi ndipakati ndi ngodya yaing'ono ya pakati pa 30 ndi 45 °. Popanga zopangazo, gwiritsani ntchito njira yowongoka ndikudula zokutira ku gawo lapansi mukuyenda kokhazikika.
7.3 Yang'anani zowunikira kuti ziwonetsere kuwala kuchokera kugawo lachitsulo kuti muwonetsetse kuti filimu yokutira yalowetsedwa. Ngati gawo lapansi silinafike pangani X ina pamalo ena. Osayesa kuzama mdulidwe wam'mbuyomu chifukwa izi zitha kukhudza kumamatira komwe kumapangidwira.
7.4 Chotsani mipiringidzo iwiri yathunthu ya tepi yovutirapo pampukutu ndikutaya. Chotsani utali wowonjezera pamlingo wokhazikika (ndiko kuti, wosagwedezeka) ndikudula chidutswa cha 75 mm (3 in.) utali.
7.5 Ikani pakati pa tepiyo pa mphambano ya mabala ndi tepi yomwe ikuyenda mofanana ndi ngodya zing'onozing'ono. Sambani tepiyo m'malo mwa chala m'dera la zodulidwazo ndiyeno pakani mwamphamvu ndi chofufutira kumapeto kwa pensulo. The mtundu pansi pa tepi yowonekera ndi chizindikiro chothandiza cha pamene kukhudzana kwabwino kwapangidwa.
7.6 Mkati mwa 90 6 30 s yogwiritsira ntchito, chotsani tepiyo pogwira mapeto aulere ndikuyikoka mofulumira (osagwedezeka) kubwerera payokha pafupi ndi ngodya ya 180 ° momwe mungathere.
7.7 Yang'anani malo odulidwa a X kuti muchotse zokutira ku gawo lapansi kapena zokutira zam'mbuyo ndikuyesa zomatira molingana ndi sikelo iyi:
5A Palibe kusenda kapena kuchotsa,
4A Tsatirani kusenda kapena kuchotsedwa panjira kapena pamphambano zawo,
3A Kuchotsa zokhotakhota m'mbali mwake mpaka 1.6 mm (1⁄16 mkati) mbali zonse,
2A Kuchotsa zokhotakhota m'mbali zambiri zocheka mpaka 3.2 mm (1⁄8 in.) mbali zonse,
1A Kuchotsedwa kumadera ambiri a X pansi pa tepi, ndi
0A Kuchotsa kupitirira dera la X.
7.8 Bwerezani mayesero m'malo ena awiri pagawo lililonse loyesera. Pakuti zomanga zazikulu zimapanga mayesero okwanira kuti zitsimikizire kuti kuwunika kumayimira kuyimira pamwamba.
7.9 Pambuyo kupanga zisanu ndi ziwiriral macheka amayesa m'mphepete mwake ndipo, ngati kuli kofunikira, chotsani madontho athyathyathya kapena mawaya pobisala pang'ono pamwala wamafuta musanagwiritsenso ntchito. Tayani zida zodulira zomwe zimapanga ma nick kapena zolakwika zina zomwe zimang'amba filimuyo.

8. Lipoti

8.1 Nenani kuchuluka kwa mayeso, tanthauzo lake ndi mtundu wake, ndi machitidwe opaka, pomwe kulephera kudachitika, ndiko kuti, pakati pa malaya oyamba ndi gawo lapansi, pakati pa malaya oyamba ndi achiwiri, ndi zina zambiri.
8.2 Pamayeso am'munda nenani za kapangidwe kake kapena nkhani yomwe idayesedwa, malo ndi momwe chilengedwe chimakhalira panthawi yoyesedwa.
8.3 Pamapulogalamu oyesa afotokozereni gawo lapansi lomwe lagwiritsidwa ntchito, mtundu wa zokutira, njira yochiritsira, komanso momwe chilengedwe chimakhalira panthawi yoyesedwa.
8.4 Ngati mphamvu yomatira ya tepiyo yatsimikiziridwa molingana ndi Njira Zoyesera D 1000 kapena D 3330, nenani zotsatirazo ndi chiwerengero cha adhesion. Ngati mphamvu yomatira ya tepiyo siinatsimikizidwe, nenani tepi yeniyeni yomwe imagwiritsidwa ntchito ndi wopanga.
8.5 Ngati mayeso achitika pambuyo pa kumizidwa, lipoti mikhalidwe yomiza ndi njira yokonzekera zitsanzo.

9. Kulondola ndi kukondera

9.1 Pakufufuza kwapang'onopang'ono kwa njira yoyesera iyi momwe ogwiritsira ntchito m'ma labotale asanu ndi limodzi adapanga muyeso umodzi womatira pamapanelo atatu chilichonse mwa zokutira zitatu zomwe zimaphimba kumatira kosiyanasiyana, kupatuka kwamkati mwama labotale kunapezeka kuti ndi 0.33 ndi ma laboratories apakati 0.44 . Kutengera zopatuka izi, njira zotsatirazi ziyenera kugwiritsidwa ntchito poweruza kuvomerezedwa kwa zotsatira pamlingo wodalirika wa 95 %:
9.1.1 Kubwerezabwereza-Kuperekedwa kumamatira ndi yunifolomu pamtunda waukulu, zotsatira zopezedwa ndi wogwiritsa ntchito yemweyo ziyenera kuganiziridwa ngati zokayikira ngati zimasiyana ndi chiwerengero cha 1 pa miyeso iwiri.
9.1.2 Kuchulukitsanso—Zotsatira ziwiri, chilichonse chofanana ndi katatu, zopezedwa ndi ogwiritsa ntchito osiyanasiyana ziyenera kuganiziridwa kuti ndi zokayikitsa ngati zikusiyana ndi mayunitsi opitilira 1.5.
9.2 Tsankho silingakhazikitsidwe panjira zoyesera izi
