Indlela yokuvavanya ubukhulu betape yokutywina

Okwangoku, izinto kuphela eziza kuvavanywa kwiimveliso ze-tape zokutywinwa kwimarike yi-viscosity kunye nobukhulu be-mold. Ngapha koko, i-viscosity ye-tape yokutywina iqulathe izikhombisi ezintathu: i-tack yayo yokuqala, ukubamba i-tack, kunye namandla e-peel. Ezi zizinto ezintathu ezisisiseko ezichazwe ngumgangatho wesizwe wovavanyo lwe-viscosity ye-tape yokutywina okanye iimveliso zokuzincamathela. Izixhobo ezihambelanayo zibizwa ngokuba ngumvavanyi wokuqala we-tack, i-tack tester kunye ne-electronic peel tester (umatshini wokuvavanya i-tensile). Unokukhetha kwakhona isixhobo sokuvavanya iteyiphu ehambelanayo ngokweemfuno zakho. I-BOPP tape yokulinganisa ubukhulu befilimu yenye yezinto ezisisiseko zokuhlola kushishino lokwenziwa kweefilimu. Ezinye izibonakaliso zokusebenza zefilimu zihambelana nobukhulu. Ngokucacileyo, ukuba ubukhulu bebhetshi yeefilimu ezinomgangatho omnye abufani, abuyi kuchaphazela kuphela amandla okuqina kunye neempawu zokuthintelwa kwefilimu, kodwa zichaphazela ukusetyenzwa okulandelayo kwefilimu. Kwiifilimu ezidibeneyo, ukufana kobunzima kubaluleke kakhulu. Kuphela xa ubukhulu bubonke bufanayo apho ubukhulu bomaleko ngamnye we-resin bufana. Ngoko ke, ingaba ubukhulu befilimu bufana, nokuba buhambelana nexabiso elimiselweyo, nokuba ukuphambuka kobuninzi kuphakathi koluhlu oluchaziweyo, zonke ezi ziba sisiseko sokuba ifilimu ingaba neempawu ezithile. Kukho iindidi ezimbini zokulinganisa ubukhulu befilimu: uvavanyo lwe-intanethi kunye novavanyo olungekho kwi-intanethi. Eyokuqala esetyenziselwa ukulinganisa ubukhulu befilimu bubuchwephesha bomlinganiselo wokutyeba ngaphandle kwe-line. Emva koko, ngophuhliso oluqhubekayo lobuchwepheshe be-ray, isixhobo sokulinganisa ubukhulu be-intanethi esifakwe kunye nomgca wokuvelisa ifilimu saphuhliswa ngokuthe ngcembe. Itekhnoloji yokulinganisa ubukhulu be-Intanethi isetyenziswe ngokubanzi ngeminyaka yoo-1960, kwaye ngoku iyakwazi ukubona ubukhulu bengubo ethile kwifilimu ebhityileyo. Itekhnoloji yokulinganisa ubukhulu be-intanethi kunye netekhnoloji yokulinganisa ubukhulu be-intanethi yahluke ngokupheleleyo kumgaqo wokuvavanya. Itekhnoloji yokulinganisa ubukhulu be-intanethi ngokuqhelekileyo isebenzisa iindlela ezingaqhagamshelwanga njengetekhnoloji ye-ray, ngelixa itekhnoloji yokulinganisa ubukhulu obungeyo-intanethi ngokuqhelekileyo isebenzisa iindlela zokulinganisa ngoomatshini okanye isekwe kwitekhnoloji ye-eddy yangoku okanye i-electromagnetic induction. Indlela yokulinganisa umgaqo ikwasebenzisa itekhnoloji yokulinganisa ubukhulu bokukhanya kunye netekhnoloji yokulinganisa ubukhulu be-ultrasonic. 1. Umlinganiselo wobukhulu be-intanethi Eyona ndlela ixhaphakileyo yokulinganisa ubukhulu be-intanethi ibandakanya ubuchwepheshe be-β-reyi, iteknoloji ye-X-reyi kunye nobuchwepheshe be-infrared. 2. Itekhnoloji yokulinganisa ubukhulu obungekho kwi-line ubukhulu becala ibandakanya iindidi ezimbini: indlela yokulinganisa umfowunelwa kunye nendlela yomlinganiselo ongaqhagamshelwanga. Indlela yokulinganisa uqhagamshelwano yeyona ndlela yokulinganisa ngoomatshini. Indlela yokulinganisa i-non-contact ibandakanya indlela yokulinganisa i-optical kunye ne-eddy yangoku yokulinganisa. Indlela, indlela yokulinganisa i-ultrasonic, njl. Ngenxa yexabiso eliphantsi kunye nobukhulu obuncinci besixhobo sokulinganisa ubukhulu be-off-line, inoluhlu olubanzi lwezicelo. Kubenzi befilimu, ukufana kobunzima bemveliso yenye yezona zibonakaliso ezibalulekileyo. Ukulawula ngokufanelekileyo ubukhulu bezinto eziphathekayo, izixhobo zokuvavanya ubukhulu zibalulekile, kodwa uhlobo oluthile lwezixhobo zokulinganisa ubukhulu obukhethiweyo kuxhomekeke kwizinto ezifana nohlobo lwempahla yokupakisha ethambileyo, iimfuno zomenzi zokufana kobukhulu, kunye novavanyo. uluhlu lwezixhobo.
