Inqubo ye-X-CUT TAPE TEST INDLELA-ASTM D3359-02

I-7. Inqubo

7.1 Khetha indawo engenawo amabala nokungapheleli okuncane kwendawo. Ukuze uthole izivivinyo ensimini, qinisekisa ukuthi ingaphezulu lihlanzekile futhi lomile. Ukushisa ngokweqile noma umswakama ohlobene kungase kuthinte ukunamathela kwe-tape noma ukumboza.
7.1.1 Ezibonelweni ezicwilisiwe: Ngemva kokucwiliswa, hlanza futhi usule indawo nge-solvent efanele engeke ilimaze ubuqotho be-coating. Bese womisa noma ulungise indawo engaphezulu, noma kokubili, njengoba kuvunyelwene phakathi komthengi nomthengisi.
7.2 Yenza ukusikeka okubili kwefilimu ngakunye okungaba ngu-40 mm (1.5 in.) ubude obuphambana eduze nendawo emaphakathi nge-engeli encane ephakathi kuka-30 no-45°. Lapho wenza ama-incision, sebenzisa i-straightedge bese usika ukugqoka ku-substrate ngokunyakaza okukodwa okuqinile.
7.3 Hlola ama-incision ukuze kukhanye ukukhanya okuvela ku-substrate yensimbi ukuze uthole ukuthi ifilimu yokumboza ingenile. Uma i-substrate ingafinyelelwanga yenza enye i-X endaweni ehlukile. Ungazami ukujulisa ukusikeka kwangaphambilini njengoba lokhu kungase kuthinte ukunamathela eduze kokusikeka.
7.4 Khipha imizuliswano emibili ephelele yetheyiphu ezwela ukucindezela emgqeni bese uyilahla. Susa ubude obengeziwe ngezinga elizinzile (okungukuthi, elinganyakazi) futhi usike ucezu olungaba ngu-75 mm (3 in.) ubude.
7.5 Beka isikhungo setheyiphu ezimpambanweni zokusikeka nge-tape egijima ngendlela efanayo nama-engeli amancane. Hlehlisa itheyiphu endaweni ngomunwe endaweni yezisikele bese uyihlikihla ngokuqinile ngerabha ekugcineni kwepensela. I umbala ngaphansi kwetheyiphu esobala kuyinkomba ewusizo yokuthi ukuxhumana okuhle kwenziwe nini.
7.6 Phakathi namasekhondi angu-90 6 30 wokufaka isicelo, susa itheyiphu ngokubamba indawo evulekile bese uyikhipha ngokushesha (hhayi ukunyakaziswa) ibuyele kuyo ngokwayo eduze ne-engeli engu-180° ngangokunokwenzeka.
7.7 Hlola indawo ye-X-cut ukuze kukhishwe okokunamathela ku-substrate noma ukunamathela okudlule bese ulinganisela ukunamathela ngokuhambisana nesilinganiso esilandelayo:
5A Akukho ukuxebuka noma ukususwa,
4A Ukulandelela ukuxebuka noma ukususwa eduze kwezisikele noma ezimpambanweni zazo,
3A Ukususwa okumangelengele ngokusikwa kufika ku-1.6 mm (1⁄16 in.) nhlangothi zombili,
2A Ukususwa okumangelengele eduze kweningi lokusikeka kufika ku-3.2 mm (1⁄8 in.) nhlangothi zombili,
1A Ukususwa ezindaweni eziningi ze-X ngaphansi kwetheyiphu, futhi
0A Ukususwa ngale kwendawo ye-X.
7.8 Phinda ukuhlolwa kwezinye izindawo ezimbili kuphaneli yokuhlola ngayinye. Ukuze izakhiwo ezinkulu yenza izivivinyo ezanele ukuze uqinisekise ukuthi ukuhlola ukunamathela kumelela yonke indawo.
7.9 Ngemva kokwenza isikhombisaral ukusikeka kuhlola unqenqema lokusika futhi, uma kunesidingo, susa noma yimaphi amachashaza ayisicaba noma unqenqema locingo ngokuhuzuka kancane etsheni likawoyela elicolekileyo ngaphambi kokulisebenzisa futhi. Lahla amathuluzi okusika athuthukisa ama-nick noma ezinye izinkinga ezidabula ifilimu.

8. Bika

8.1 Bika inani lokuhlola, isilinganiso sakho nobubanzi, kanye nezinhlelo zokumboza, lapho kwenzeke khona ukwehluleka okungukuthi, phakathi kwejazi lokuqala ne-substrate, phakathi kwejazi lokuqala nelesibili, njll.
8.2 Ngokuhlolwa kwenkundla bika isakhiwo noma i-athikili ehloliwe, indawo kanye nezimo zemvelo ngesikhathi sokuhlolwa.
8.3 Kumaphaneli okuhlola bika i-substrate esetshenzisiwe, uhlobo lokumboza, indlela yokwelapha, nezimo zemvelo ngesikhathi sokuhlolwa.
8.4 Uma amandla okunamathela etheyiphu enqunywe ngokuhambisana Nezindlela Zokuhlola D 1000 noma D 3330, bika imiphumela ngezilinganiso zokunamathela. Uma amandla okunamathela we-tape engakanqunywa, bika i-tape ethile esetshenzisiwe kanye nomkhiqizi wayo.
8.5 Uma ukuhlolwa kwenziwa ngemva kokucwiliswa, bika izimo zokucwiliswa kanye nendlela yokulungiselela isampula.

9. Ukunemba nokuchema

9.1 Ocwaningweni lwangaphakathi lwale ndlela yokuhlola lapho ama-opharetha emalabhorethri ayisithupha enza isilinganiso esisodwa sokunamathela kumaphaneli amathathu ngakunye kokunamathelayo okuhlanganisa uhla olubanzi lokunamathela, ukuchezuka okujwayelekile kwangaphakathi kwelabhorethri kutholwe kungu-0.33 kanti amalabhorethri aphakathi kwawo angu-0.44 . Ngokusekelwe kulokhu kuchezuka okujwayelekile, le mibandela elandelayo kufanele isetshenziselwe ukwahlulela ukwamukelwa kwemiphumela ezingeni lokuzethemba elingu-95 %:
9.1.1 Ukuphindaphinda—Ukunamathela okunikezwayo kufana nendawo enkulu, imiphumela etholwe isisebenzisi esifanayo kufanele ibhekwe njengesolisayo uma ihluka ngeyunithi yokulinganisa engaphezu kuka-1 ezilinganisweni ezimbili.
9.1.2 Ukukhiqiza kabusha—Imiphumela emibili, ngayinye isho ukuphindaphindeka kathathu, etholwe abaqhubi abahlukene kufanele kubhekwe njengesoleka uma ihluke ngamayunithi okulinganisa angaphezu kuka-1.5.
9.2 Ukuchema akukwazi ukusungulwa kulezi zindlela zokuhlola
