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

7. Inkqubo

7.1 Khetha indawo engenamabala kunye nokungafezeki okungephi. Uvavanyo ebaleni, qinisekisa ukuba umphezulu ucocekile kwaye womile. Ukugqithiswa kweqondo lokushisa okanye ukufuma okuhambelanayo kunokuchaphazela ukunamathela kwe-tape okanye ukugquma.
7.1.1 Kwimizekelo entywilisiweyo: Emva kokuntywiliselwa, coca kwaye wosule umphezulu ngesinyibilikisi esifanelekileyo esingayi kulimaza ingqibelelo yengubo. Emva koko womise okanye ulungise umphezulu, okanye zombini, njengoko kuvunyelwene phakathi komthengi nomthengisi.
7.2 Yenza iindawo ezimbini zokusikeka kwifilim nganye malunga ne-40 mm (1.5 in.) ubude ezinqumla kufutshane nombindi wazo nge-engile encinci ephakathi kwama-30 nama-45°. Xa usenza i-incisions, sebenzisa i-straightedge kwaye unqumle i-coating ukuya kwi-substrate kwintshukumo enye yokuzinza.
7.3 Hlola izithintelo zokubonisa ukukhanya kwi-substrate yesinyithi ukufumanisa ukuba ifilimu yokwambathisa ingenile. Ukuba i-substrate ayifikelelwanga yenza enye i-X kwindawo eyahlukileyo. Ungazami ukwenza nzulu isikelelo sangaphambili njengoko oku kunokuchaphazela ukuncamathela ecaleni kosiko.
7.4 Susa imilenze emibini epheleleyo ye-tape ye-pressure-sensitive tape kwi-roll kwaye uyilahle. Susa ubude obongezelelweyo kwinqanaba elizinzileyo (oko kukuthi, lingaxutywanga) kwaye usike isiqwenga malunga ne-75 mm (3 in.) ubude.
7.5 Beka i-center of the tape kwi-intersection of cuts kunye ne-tape ehamba ngendlela efanayo nama-angles amancinci. Gcoba iteyiphu kwindawo ngomnwe kwindawo yokusikeka kwaye emva koko uhlikihle ngokuqinileyo ngerabha ekupheleni kwepensile. I umbala phantsi kweteyiphu ecacileyo luphawu oluluncedo xa unxibelelwano oluhle lwenziwe.
7.6 Ngaphakathi kwe-90 6 30 s yesicelo, susa iteyiphu ngokubamba isiphelo esikhululekileyo kwaye uyitsale ngokukhawuleza (ingashukumi) ubuyisele kuyo ngokwayo kufutshane ne-engile ye-180 ° kangangoko kunokwenzeka.
7.7 Hlola indawo ye-X-cut yokukhutshwa kwengubo kwi-substrate okanye i-coating yangaphambili kwaye ulinganise ukunamathela ngokuhambelana nesikali esilandelayo:
5A Akukho kuxobula okanye ukususwa,
4A Umkhondo wokuxobula okanye ukususwa ecaleni kweendawo ezisikelelweyo okanye ekudibaneni kwazo,
3A Ukususwa kweJagged ecaleni kwendlela ukuya kuthi ga kwi-1.6 mm (1⁄16 in.) macala omabini,
2A Ukususwa kweJagged kunye noninzi lwezikeko ukuya kuthi ga kwi-3.2 mm (1⁄8 in.) macala omabini,
1A Ukususwa kwiindawo ezininzi ze-X phantsi kwetape, kunye
0A Ukususwa ngaphaya kwendawo ye-X.
7.8 Phinda uvavanyo kwezinye iindawo ezimbini kwiphaneli yovavanyo nganye. Kuba izakhiwo ezinkulu zenza iimvavanyo ezaneleyo zokuqinisekisa ukuba uvavanyo lokubambelela lumele umhlaba wonke.
7.9 Emva kokwenza isixhenxeral ukusika kuphonononge i-edge yokusika kwaye, ukuba kuyimfuneko, susa nawaphi na amabala acaba okanye i-wire-edge ngokugqabhuka kancinane kwilitye le-oyile elicolekileyo ngaphambi kokuba usebenzise kwakhona. Lahla izixhobo zokusika eziphuhlisa iziqhulo okanye ezinye iziphene ezikrazula ifilimu.

8. Ingxelo

8.1 Xela inani leemvavanyo, intsingiselo yazo kunye noluhlu, kunye neenkqubo zokugquma, apho ukusilela kwenzeke oko kukuthi, phakathi kwedyasi yokuqala kunye ne-substrate, phakathi kwedyasi yokuqala neyesibini, njl.
8.2 Kwiimvavanyo zangaphandle xela ubume okanye inqaku elivavanyiweyo, indawo kunye neemeko zokusingqongileyo ngexesha lovavanyo.
8.3 Iiphaneli zovavanyo zixela i-substrate esetyenzisiweyo, uhlobo lokwaleka, indlela yokunyanga, kunye neemeko zokusingqongileyo ngexesha lovavanyo.
8.4 Ukuba amandla okubambelela kwiteyiphu amiselwe ngokungqinelana neeNdlela zoVavanyo D 1000 okanye i-D 3330, zixele iziphumo ngohlelo lokuncamathisela (ii-adhesion rating). Ukuba amandla okubambelela kwi-tape ayikagqitywa, xela i-tape ethile esetyenzisiweyo kunye nomenzi wayo.
8.5 Ukuba uvavanyo lwenziwa emva kokucwiliswa, xela iimeko zokucwiliswa kunye nendlela yokulungiselela isampuli.

9. Ukuchaneka kunye ne-Bias

9.1 Kuphononongo lwangaphakathi lwale ndlela yovavanyo apho abaqhubi kwiilabhoratri ezintandathu benze umlinganiselo wokuncamathelisa omnye kwiiphaneli ezintathu nganye kwiingubo ezintathu ezigquma uluhlu olubanzi lokunamathela, ukutenxa okusemgangathweni kwangaphakathi kweelabhoratri kwafunyaniswa kuyi-0.33 kunye ne-0.44 phakathi kweelabhoratri ze-95 . Ngokusekwe kolu tshintsho lusemgangathweni, le migaqo ilandelayo kufuneka isetyenziswe xa kujongwa ukwamkelwa kweziphumo kwi-XNUMX% yenqanaba lokuzithemba:
9.1.1 Ukuphindaphinda-Ukunikezelwa kokubambelela kufanayo phezu kwendawo enkulu, iziphumo ezifunyenwe ngumqhubi ofanayo kufuneka zicatshangelwe ukuba zikrokre xa zihluke ngaphezu kweyunithi yokulinganisa i-1 kwimilinganiselo emibini.
9.1.2 Ukuveliswa kwakhona—Iziphumo ezimbini, nganye intsingiselo yee-triplicates, ezifunyenwe ngabaqhubi abahlukeneyo kufuneka zithathwe njengezikrokro ukuba ziyahluka ngeeyunithi zokulinganisa ezingaphezu kwe-1.5.
9.2 I-bias ayinakusekwa kwezi ndlela zovavanyo
