Indlela Yokulinganisa Ukuhlolwa Kwe-Coating Adhesion-Tape
Isivivinyo esivame kakhulu sokuhlola ukunamathela enamathela ukuhlolwa kwe-tape-and-peel, obekusetshenziswa kusukela ngawo-1930. Enguqulweni yayo elula ucezu lwe-adhesive tape lucindezelwa ngokumelene nefilimu kapende kanye nokumelana nezinga lokususwa kwefilimu okubonwa lapho itheyipu ikhishwa. Njengoba ifilimu engaguquki enamathelayo enamathelayo ngokuvamile ayisuswa nhlobo, ubukhulu bokuhlolwa ngokuvamile buthuthukiswa ngokusika ifilimu umfanekiso X noma iphethini enqanyuliwe, ngaphambi kokufaka nokukhipha itheyiphu. Ukunamathela bese kukalwa ngokuqhathanisa ifilimu esusiwe esikalini sokulinganisa esimisiwe. Uma ifilimu eqinile ihlutshiwe ngokuhlanzekile yi-tape, noma uma iboshiwe ngokusika kuyo ngaphandle kokufaka i-tape, ukunamathela kulinganisa nje njengokumpofu noma kubi kakhulu, ukuhlolwa okunembe kakhudlwana kwamafilimu anjalo angekho ngaphakathi kwamandla alokhu. test.
Inguqulo yamanje esetshenziswa kabanzi yashicilelwa okokuqala ngo-1974; izindlela ezimbili zokuhlola zihlanganiswa kuleli zinga. Zombili izindlela zokuhlola zisetshenziselwa ukuthola ukuthi ukunamathela kokunamathela ku-substrate kusezingeni elanele yini; nokho abahlukanisi phakathi kwamazinga aphezulu okunamathela okudingeka kuwo izindlela eziyinkimbinkimbi zokulinganisa.Imikhawulo emikhulu yokuhlolwa kwetheyiphu ukuzwela kwayo okuphansi, ukusebenza kuphela kwezingubo zamandla ebhondi aphansi, kanye nokunganqunywa kokunamathela ku-substrate. lapho ukwehluleka kwenzeka khona ngaphakathi kwejazi elilodwa, njengalapho kuhlolwa iziqalo zodwa, noma ngaphakathi noma phakathi kwamajazi kumasistimu ama-multicoat. Kuzinhlelo ze-multicoat lapho ukwehluleka ukunamathela kungase kwenzeke phakathi noma ngaphakathi kwamajazi, ukunamathela kwesistimu yokumboza ku-substrate akunqunywa.
Ukuphindaphinda ngaphakathi kweyunithi yokulinganisa eyodwa kuwufuzoralkuqashelwe kahle ukuze kuhlanganiswe izinsimbi kuzo zombili izindlela, nokuphindaphindeka kweyunithi eyodwa kuya kwamabili. Ukuhlolwa kwe-tape kuthokozela ukuthandwa okubanzi futhi kubhekwa “njengolula” kanye nezindleko eziphansi. Isetshenziswa ezinsimbi, iyonga ukwenza, iboleka ekufakweni kwesicelo sesizinda somsebenzi, futhi okubaluleke kakhulu, ngemva kwamashumi eminyaka yokusetshenziswa, abantu bazizwa bekhululekile ngayo.
Uma i-tape yokunamathisela eguquguqukayo isetshenziswa endaweni ehlanganisiwe eqinile ye-substrate bese isuswa, inqubo yokususa ichazwe ngokwemibandela "ye-peel phenomenon," njengoba kuboniswe ku-Fig. X1.1.
Ukucwecwa kuqala “onqenqemeni olunamazinyo” (ngakwesokudla) futhi kuqhubekele phambili ngento enamathelayo/isixhumi esibonakalayo noma isixhumi esibonakalayo sokumboza/sangaphansi, kuye ngamandla esibopho esihlobene. Kucatshangwa ukuthi ukususwa kwe-coating kwenzeka lapho amandla aqinile akhiqizwe eduze kwesixhumi esibonakalayo sakamuva, okuwumsebenzi wezakhiwo ze-rheological zezinto ezisekelayo nezinamathelayo zongqimba, mkhulu kunamandla ebhondi kusixhumi esibonakalayo se-coating-substrate (noma amandla ahlangene i-coating).Kodwa-ke, empeleni, la mandla asakazwa ngebanga eliqondile (OA) ku-Fig. X1.1, ehlobene ngokuqondile nezakhiwo ezichazwe, ezingagxiliwe endaweni ethile (O) ku-Fig.
Njengasendabeni yethiyori—nakuba amandla aqinile amakhulu kunawo womabili. Amandla acindezelayo abalulekile avela empendulweni ye-tape esekelayo yokwelulwa. Ngakho-ke kokubili amandla aqinile nacindezelayo ahilelekile ekuhlolweni kwe-adhesion tape.
Ukucutshungulwa ngokucophelela kokuhlolwa kwetheyiphu ngokuphathelene nohlobo lwetheyiphu esetshenzisiwe kanye nezici ezithile zenqubo ngokwayo kuveza okuyisikhombisa.ral izici, ngayinye noma iyiphi inhlanganisela engathinta kakhulu imiphumela yokuhlolwa njengoba kuxoxiwe (6).
