Ungahlola kanjani ubukhulu be-tape yokuvala

Njengamanje, okuwukuphela kwezinto okufanele zihlolwe imikhiqizo ye-tape yokuvala emakethe i-viscosity kanye nobukhulu besikhunta. Eqinisweni, i-viscosity ye-tape yokuvala ngokuyinhloko iqukethe izinkomba ezintathu: i-tack yayo yokuqala, i-tack yokubamba, namandla okuxebula. Lezi futhi izinto ezintathu eziyisisekelo ezishiwo yindinganiso kazwelonke yokuhlolwa kwe-viscosity ye-sealing tape noma imikhiqizo ezinamathelayo. Amathuluzi ahambisanayo abizwa ngokuthi i-initial tack tester, i-tack tester kanye ne-electronic peel tester (umshini wokuhlola i-tensile). Ungaphinda ukhethe ithuluzi lokuhlola i-tape elihambisanayo ngokwezidingo zakho. Isilinganiso sefilimu ye-tape ye-BOPP singenye yezinto eziyisisekelo zokuhlola embonini yokukhiqiza amafilimu. Ezinye izinkomba zokusebenza zefilimu zihlobene nokuqina. Ngokusobala, uma ubukhulu beqoqo lamafilimu ongqimba olulodwa bungafani, ngeke nje buthinte amandla aqinile kanye nezindawo zokuvimbela ifilimu, kodwa futhi kuthinte ukucubungula okulandelayo kwefilimu. Kumafilimu ahlanganisiwe, ukufana kokuqina kubaluleke kakhulu. Kuphela uma ukushuba okuphelele kufana nendawo lapho ukushuba kongqimba ngalunye lwe-resin kungafana. Ngakho-ke, noma ngabe ubukhulu befilimu bufana, noma ngabe buhambisana nevelu elisethiwe, noma ngabe ukuchezuka kogqinsi kungaphakathi kwebanga elishiwo, konke lokhu kuba isisekelo sokuthi ifilimu ingaba nezici ezithile yini. Kunezinhlobo ezimbili zokulinganisa ubukhulu befilimu: ukuhlola ku-inthanethi nokuhlola ungaxhunyiwe ku-inthanethi. Esokuqala esisetshenziselwa ukukala ukushuba kwefilimu ubuchwepheshe bokulinganisa ukushuba okungaxhunyiwe ku-inthanethi. Ngemva kwalokho, ngokuthuthukiswa okuqhubekayo kobuchwepheshe be-ray, umshini wokukala ukushuba okuku-inthanethi ofakwe nolayini wokukhiqiza ifilimu wathuthukiswa kancane kancane. Ubuchwepheshe bokulinganisa ukushuba ku-inthanethi busetshenziswe kabanzi ngeminyaka yawo-1960, futhi manje sebukwazi ukubona ukushuba koqweqwe oluthile lwefilimu elincanyana. Ubuchwepheshe bokulinganisa ukushuba ku-inthanethi kanye nobuchwepheshe bokulinganisa ukushuba okungaxhunyiwe ku-inthanethi kuhluke ngokuphelele esimisweni sokuhlola. Ubuchwepheshe bokulinganisa ukushuba okuku-inthanethi ngokuvamile busebenzisa izindlela zokulinganisa okungathinteki muntu kuzo njengobuchwepheshe be-ray, kuyilapho ubuchwepheshe bokulinganisa ukushuba okungaxhumene ku-inthanethi ngokuvamile busebenzisa izindlela zokulinganisa zemishini noma busekelwe kubuchwepheshe bamanje be-eddy noma ukungeniswa kwe-electromagnetic. Indlela yokulinganisa yomgomo ibuye isebenzise ubuchwepheshe bokulinganisa ukuqina kwe-optical kanye nobuchwepheshe bokulinganisa ukushuba kwe-ultrasonic. 1. Isilinganiso sobukhulu be-inthanethi Izindlela zokulinganisa ukushuba kwe-inthanethi ezivame kakhulu zihlanganisa ubuchwepheshe be-β-ray, ubuchwepheshe be-X-ray kanye nobuchwepheshe obuseduze ne-infrared. 2. Isilinganiso sobukhulu obungaxhunyiwe ku-inthanethi Ubuchwepheshe bokulinganisa ukushuba okungaxhunyiwe ku-inthanethi ikakhulukazi buhlanganisa izinhlobo ezimbili: indlela yokulinganisa othintana naye kanye nendlela yokulinganisa ongathintana naye. Indlela yokulinganisa othintana naye ngokuyinhloko iyindlela yokulinganisa eyimishini. Indlela yokulinganisa okungeyena othintana naye ihlanganisa indlela yokulinganisa yokubona kanye nesilinganiso samanje se-eddy. Indlela, indlela yokulinganisa ye-ultrasonic, njll. Ngenxa yentengo ephansi nobukhulu obuncane bemishini yokulinganisa ukushuba okungaxhunyiwe ku-inthanethi, inezinhlelo eziningi zokusebenza. Kubakhiqizi befilimu, ukufana kokuqina komkhiqizo kungenye yezinkomba ezibaluleke kakhulu. Ukulawula ngempumelelo ukushuba kwezinto, imishini yokuhlola ukujiya ibalulekile, kodwa uhlobo oluthile lwemishini yokulinganisa ukujiya okufanele lukhethwe kuya ngokuthi Kuncike ezintweni ezinjengohlobo lwempahla yokupakisha ethambile, izidingo zomkhiqizi zokufana kogqinsi, kanye nokuhlolwa. ububanzi bemishini.
