UVAVANYO INDLELA-UMNQANDA-KUKA-TAPE UVAVANYO-ASTM D3359-02

10. Izixhobo kunye nezixhobo

10.1 Isixhobo sokusika 9—Incakuba ebukhali, incakuba ebukhali, imela okanye esinye isixhobo sokusika esine-engile yokusika phakathi kwe-15 kunye ne-30° eya kwenza nokuba kukusikwa okukodwa okanye ukusika.ral ukusikwa kwangoko. Kubaluleke kakhulu ukuba i-cut cut or edges ibekwimeko entle.
10.2 Isikhokelo sokusika—Ukuba ukusikwa kwenziwa ngesandla (ngokuchaseneyo nesixhobo somatshini) intsimbi okanye enye i-straightedge yentsimbi eqinile okanye itemplate ukuqinisekisa ukusikwa ngokuthe ngqo.
I-10.3 Umthetho-Umgaqo wensimbi ovuthayo uphumelele kwi-0.5 mm yokulinganisa ukusikwa komntu ngamnye.
10.4 Iteyiphu, njengoko ichaziwe ku-5.3.
10.5 Irabha yeRabha, ekupheleni kwepensile.
10.6 Ukukhanyisa, njengoko kuchaziwe ku-5.5.
10.7 Iglasi yokukhulisa—Isikhulisi esikhanyisiweyo esiza kusetyenziswa xa usika umntu ngamnye kwaye uvavanya indawo yovavanyo.

11. Imizekelo yoVavanyo

11.1 Iisampulu zovavanyo ziya kuba njengoko kuchaziwe kwiCandelo lesi-6. Kufuneka kuqatshelwe, nangona kunjalo, ukuba ii-multitip cutters10 zibonelela ngeziphumo ezilungileyo kuphela kwiindawo zovavanyo ngokwaneleyo ukuba zonke ii-cutting edges ziqhagamshelane ne-substrate kwinqanaba elifanayo. Jonga ukucaba ngomphetho othe tye njengalowo womthetho wentsimbi.

12. Inkqubo

12.1 Apho kufunekayo okanye xa kuvunyelwene ngako, kuxhomekeka kwimizekelo kuvavanyo lokuqala phambi kokwenza uvavanyo lweteyiphu (jonga inqaku lesi-3). Emva kokumisa okanye ukuvavanya i-coating, qhuba uvavanyo lwe-tape kwiqondo lokushisa eliqhelekileyo njengoko kuchazwe kwi-Specification D 3924, ngaphandle kokuba i-D 3924 iqondo lokushisa eliqhelekileyo liyafuneka okanye livunyelwene.
12.1.1 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.
12.2 Khetha indawo engenaziphako kunye nokungafezeki okuncinci komphezulu, beka kwisiseko esiqinileyo, kwaye phantsi kwesikhulisi esikhanyisiweyo, yenzarallel cuts ngolu hlobo lulandelayo:
12.2.1 Kwizinto zokwaleka ezinobunzima befilimu eyomileyo ukuya kuthi ga kunye nokuquka isithuba se-2.0 mils (50 μm) ukusikwa nge-1 mm ukuqelelana kwaye wenze ukusikeka kweshumi elinanye ngaphandle kokuba kuvunyelwene ngenye indlela.
12.2.2 Kwiingubo ezinobunzima befilimu eyomileyo phakathi kwe-2.0 mils (50 μm) kunye ne-5 mils (125 μm), indawo yokusikwa kwe-2 mm ngaphandle kwaye wenze ukusikwa ezintandathu. Kwiifilimu ezityebileyo kune-5 mils sebenzisa Indlela yoVavanyo A.11
12.2.3 Yenza onke amanxeba malunga ne-20 mm (3⁄4 in.) ubude. Sika ifilimu kwi-substrate kwintshukumo enye ezinzileyo usebenzisa uxinzelelo olwaneleyo kwisixhobo sokusika ukuze umgca wokusika ufikelele kwi-substrate. Xa usenza ukusikwa okulandelelanayo okukodwa ngoncedo lwesikhokelo, beka isikhokelo kwindawo enganqunyulwanga.
12.3 Emva kokwenza ukusikwa okufunekayo xuba ifilimu ngokulula ngebrashi ethambileyo okanye izicubu ukususa naziphi na iiflakes okanye iiribhoni zokwaleka.
12.4 Jonga i-edge yokusika kwaye, ukuba kukho imfuneko, susa nawaphi na amabala asicaba okanye i-wire-edge ngokugqabhuka kancinci kwilitye le-oyile elicolekileyo. Yenza inani elongezelelweyo lokusikeka kwi-90 ° ukuya kwaye ugxininise kwi-cuts original.
12.5 Gcoba indawo njengangaphambili kwaye ujonge iindawo zokuhombisa ukukhanya okuvela kwi-substrate. Ukuba isinyithi asifikelelwanga yenza enye igridi kwindawo eyahlukileyo.
12.6 Susa imijikelo emibini epheleleyo yeteyiphu kwaye uyilahle. Susa ubude obongezelelweyo kwinqanaba elizinzileyo (oko kukuthi, lingaxutywanga) kwaye usike isiqwenga malunga ne-75 mm (3 in.) ubude.
12.7 Beka umbindi we-tape phezu kwegridi kunye nommandla wegridi egudileyo kwindawo ngomnwe. Ukuqinisekisa ukuba unxibelelwano oluhle kunye nefilimu gcoba i-tape ngokuqinileyo kunye ne-eraser ekupheleni kwepensile. I umbala phantsi kweteyiphu luphawu oluluncedo xa unxibelelwano oluhle lwenziwe.
12.8 Ngaphakathi kwe-90 6 30 yesicelo, susa iteyiphu ngokubamba indawo ekhululekileyo kwaye ngokukhawuleza (ingashukumi) ubuyele kuyo ngokusondeleyo kwi-engile ye-180 ° kangangoko kunokwenzeka.
12.9 Hlola indawo yegridi ukuze kususwe i-coating kwi-substrate okanye kwi-coating yangaphambili usebenzisa isikhulisa-mandla esikhanyisiweyo. Ukulinganisa ukunamathela ngokuhambelana nesikali esilandelayo esiboniswe kwi-Fig. akukho nasinye sezikwere zeletiyisi esizithunyiweyo.
I-4B Iiflekhi ezincinci zokugquma zivaliwe kwiindawo zokuhlangana; ngaphantsi kwe-5 % yendawo echaphazelekayo.
I-3B Iiflekhi ezincinci zokwaleka zikhutshiwe ecaleni kwemida kunye nakwiindlela zokusikwa. Indawo echaphazelekayo yi-5 ukuya kwi-15 % ye-lattice.
I-2B I-coating i-flaked ecaleni kwe-edges kunye nakwiindawo zesikwere. Indawo echaphazelekayo yi-15 ukuya kwi-35% ye-lattice.
1B I-coating igqabhukile ecaleni kwencam yokusikwa kwiiribhoni ezinkulu kwaye izikwere ezipheleleyo ziye zaqhawuka. Indawo echaphazelekayo yi-35 ukuya kwi-65 % ye-lattice.
0B Ukuqhawuka nokwahlukaniswa kubi kuneBanga loku-1.
12.10 Phinda uvavanyo kwezinye iindawo ezimbini kwiphaneli yovavanyo nganye.

13. Ingxelo

13.1 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;
njalo
13.2 Xela i-substrate esetyenzisiweyo, uhlobo lokwaleka kunye nendlela yokunyanga.
13.3 Ukuba ukuqina kokubambelela kuye kwamiselwa ngokungqinelana neeNdlela zoVavanyo D 1000 okanye i-D 3330, zixele iziphumo ngohlelo lokuncamathisela (i-adhesion rating). Ukuba amandla okubambelela kwi-tape ayikagqitywa, xela i-tape ethile esetyenzisiweyo kunye nomenzi wayo.
13.4 Ukuba uvavanyo lwenziwa emva kokucwiliswa, xela iimeko zokucwiliswa kunye nendlela yokulungiselela isampuli.

14. Ukuchaneka kunye ne-Bias

14.1 Ngokusekelwe kwiimvavanyo ezimbini zelebhu zale ndlela yovavanyo kwenye apho abaqhubi kwiilabhoratri ezintandathu benza imilinganiselo yokuncamathela enye kwiipaneli ezintathu nganye yokwaleka ezintathu ezigquma ukuncamathela okubanzi kwaye kwabanye abaqhubi kwiilabhoratri ezintandathu benza imilinganiselo emithathu kwiipaneli ezimbini. nganye yokwaleka ezine ezahlukeneyo ezisetyenziswa phezu kwezinye ezimbini zokwaleka, ukutenxa umgangatho ezidityanisiweyo ngaphakathi- naphakathi iilebhu kwafunyaniswa ukuba 0.37 yaye 0.7. Ngokusekwe kolu tshintsho lusemgangathweni, le migaqo ilandelayo kufuneka isetyenziswe xa kujongwa ukwamkelwa kweziphumo kwi-95% yenqanaba lokuzithemba:
14.1.1 Ukuphindaphinda-Ukunikezelwa kokubambelela kufanayo phezu kwendawo enkulu, iziphumo ezifunyenwe ngumqhubi ofanayo kufuneka zithathwe njengezikrokro xa zihluke ngaphezu kweyunithi enye yokukala kwimilinganiselo emibini.
14.1.2 Ukuveliswa kwakhona—Iziphumo ezibini, nganye intsingiselo yokuphinda-phinda okanye ukuphinda kabini, ezifunyenwe ngabaqhubi abahlukeneyo kufuneka zithathwe njengezikrokreleka ukuba ziyahluka ngeeyunithi zokureyitha ezingaphezu kwesibini.
14.2 I-bias ayinakusekwa kwezi ndlela zovavanyo.
