Isifinyezo
Leli phepha lenza ucwaningo mayelana nokwenza kahle nokusebenza kweama-sealants. Izici ezibalulekile ezithinta ukusebenza kwama-sealant zihlolisiswe ngokuhlaziya ukubunjwa, izici nezindawo zokusetshenziswa kwe-sealant. Ucwaningo lugxile ekukhetheni nasekusebenziseni izinto ezinamathelayo, ama-substrates nezithasiselo, kanye nokwenza ngcono izinqubo zokukhiqiza. Imiphumela yabonisa ukuthi amandla okunamathela, ukumelana nesimo sezulu semvelo kanye nokuvikelwa kwemvelo kwe-sealant eyenziwe kahle kwathuthukiswa kakhulu. Lolu cwaningo luhlinzeka ngesisekelo setiyetha kanye nesiqondiso esisebenzayo sokuthuthukiswa kokusebenza kweglue yokupakisha kanye nokuthuthukiswa kwemikhiqizo emisha, ebaluleke kakhulu ukukhuthaza ukuthuthukiswa kwemboni yokupakisha.

Isingeniso
Njengento ebalulekile embonini yesimanje yokupakisha, ukusebenza kweglue yokupakisha kuthinta ngqo ikhwalithi yokupakisha nokuphepha kwezokuthutha. Ngokuthuthuka okusheshayo kwe-e-commerce kanye nezidingo zemvelo ezikhulayo, izidingo eziphakeme ziye zabekwa phambili ekusebenzeni kwe-glue yokupakisha. Inhloso yalolu cwaningo ukuthuthukisa ukusebenza okuphelele kwama-sealant ngokuthuthukisa ukwakheka kanye nenqubo yokukhiqiza yama-sealant ukuze ahlangabezane nesidingo semakethe.
Eminyakeni yamuva, osolwazi basekhaya nabaphesheya baye benza ucwaningo olunzulu ngokupakisha iglue. Smith et al. lifunde imiphumela yokunamatheliswa okuhlukene ekusebenzeni kwezinsimbi, kuyilapho ithimba likaZhang ligxile ekuthuthukisweni kwezinsimbi ezivikela imvelo. Kodwa-ke, ucwaningo mayelana nokwenza kahle okuphelele kokusebenza kwe-sealant alukanele. Lesi sihloko sizoqala ekukhethweni kwezinto zokwakha, ukwenziwa ngcono kokwakhiwa kanye nokuthuthukiswa kwenqubo yokukhiqiza, futhi sihlole ngokuhlelekile izindlela zokuthuthukisa ukusebenza kweglue yokupakisha.
I. Ukwakheka nezici zeukupakisha iglue
I-sealant ngokuyinhloko iqukethe izingxenye ezintathu: i-adhesive, substrate kanye nesengezo. Ama-Adhesives yizithako eziyinhloko ezinquma izakhiwo zama-sealants, futhi zivame ukutholakala ku-acrylic, irabha kanye ne-silicone. I-substrate ngokuvamile ifilimu ye-polypropylene noma iphepha, futhi ukushuba kwayo kanye nokwelashwa kwendawo kuzothinta izakhiwo zemishini ye-tape. Izithasiselo zihlanganisa ama-plasticizers, ama-fillers kanye nama-antioxidants ukuthuthukisa izakhiwo ezithile ze-tape.
Izakhiwo ze-sealant ikakhulukazi zihlanganisa ukunamathela, ukunamathela kokuqala, ukubamba ukunamathela, ukumelana nesimo sezulu semvelo nokuvikelwa kwemvelo. Amandla esibopho anquma amandla okubopha phakathi kwe-tape ne-adhesive, futhi iyinkomba ebalulekile yokusebenza kwe-sealant. I-viscosity yokuqala ithinta ikhono lokuqala lokunamathela le-tape, kuyilapho i-viscosity ye-tape ibonisa ukuzinza kwayo kwesikhathi eside. Ukumelana nesimo sezulu semvelo kuhlanganisa ukumelana nokushisa okuphezulu, ukumelana nokushisa okuphansi nokumelana nomswakama. Ukuvikelwa kwemvelo kugxile ezintweni ezigugulekayo nezingenabuthi ze-duct tape, ehlangabezana nezidingo zentuthuko esimeme zezinto zokupakisha zesimanje.
II. Izindawo zokufaka ama-sealants
Ama-sealants asetshenziswa kakhulu ekupakisheni ezimbonini ezahlukahlukene. Ku-logistics, ama-sealant anamandla aphezulu asetshenziselwa ukuvikela amabhokisi esindayo futhi aqinisekise ukuphepha kwempahla ekuthuthweni okude. Ukupakishwa kwe-E-commerce kudinga ukuthi ama-sealants abe ne-viscosity enhle yokuqala futhi abambe ukunamathela ukuze abhekane nokuhlunga nokuphatha njalo. Emkhakheni wokupakisha ukudla, kuyadingeka ukusebenzisa ama-sealants anobungani bemvelo ukuze kuqinisekiswe ukuphepha kokudla kanye nenhlanzeko.
Ezimweni ezikhethekile, ukusetshenziswa kwama-sealant kuyinselele kakhulu. Isibonelo, ekusetshenzisweni kwamaketanga abandayo, i-glue yokupakisha idinga ukumelana nokushisa okuhle kakhulu; Ezindaweni zokushisa eziphakeme kanye nomswakama, i-tape iyadingeka ukuze ibe nokumelana okuhle kokushisa. Ngaphezu kwalokho, ezinye izimboni ezikhethekile ezifana ne-electronics kanye nokupakishwa kwemithi zibeka izidingo eziphakeme ekuvikelweni kwe-electrostatic kanye nezakhiwo ezilwa namagciwane zama-sealant. Lezi zidingo ezahlukahlukene zohlelo lokusebenza ziqhuba ukuqamba okusha okuqhubekayo nokuthuthukiswa kobuchwepheshe be-sealant.
III. Ucwaningo mayelana nokwenza kahle kokusebenza kwe-sealant
Ukuze kuthuthukiswe ukusebenza okuphelele kwama-sealants, lolu cwaningo lubheka izici ezintathu zokukhethwa kwempahla, ukuthuthukiswa kokubunjwa kanye nenqubo yokukhiqiza. Lapho kukhethwa izinto zokunamathisela, izakhiwo zezinto ezintathu, i-acrylic, irabha ne-silicone, zaqhathaniswa, kanti i-acrylic yaba nenzuzo ezintweni eziphelele. Ukusebenza kwe-adhesive ye-acrylic kwathuthukiswa nakakhulu ngokulungisa ingxenye ye-monomer nesisindo se-molecule.
Ukwenziwa kahle kwama-substrates kugxile kakhulu ekujimeni nasekuphathweni kwendawo.Ukuhlola kubonisa ukuthi ifilimu ye-polypropylene ewugqinsi engu-38μm ugqinsi ifinyelela ibhalansi engcono kakhulu phakathi kwamandla nezindleko.Ukwelashwa kwe-electrode engaphezulu kuthuthukisa kakhulu amandla angaphezulu we-substrate futhi kuthuthukisa amandla okubopha ngento enamathelayo. Kwasetshenziswa ama-plasticizers emvelo esikhundleni sezinto zendabuko ezisekelwe ku-petroleum, futhi i-nano-SiO2 yengezwe ukuthuthukisa ukumelana nokushisa.
Ukuthuthukiswa kwenqubo yokukhiqiza kuhlanganisa ukuthuthukiswa kwendlela yokugqoka kanye nokulawulwa kwezimo zokuphulukisa. Ukusebenzisa ubuchwepheshe be-micro-gravure coating, ukunamathela okufanayo kwe-adhesive kuyabonakala, futhi ubukhulu bulawulwa ku-20 ± 2 μm. Ucwaningo lokushisa kanye nesikhathi sokuphulukisa kubonise ukuthi ukuphulukiswa ku-80 ° C kumaminithi angu-3 kuveza amandla okusebenza kahle kakhulu, imiphumela emihle kakhulu yemizuzu engu-3. i-sealant yanda ngo-30%, ukumelana nesimo sezulu semvelo kwathuthukiswa kakhulu, futhi ukukhishwa kwe-VOC kwehliswe ngama-50%.
IV. IZIPHETHO
Lolu cwaningo luthuthukise kakhulu ukusebenza kwalo okuphelele ngokulungiselela kahle ukwakheka kanye nenqubo yokukhiqiza ye-sealant. I-sealant eyenziwe kahle ifinyelele izinga elihamba phambili embonini mayelana nokunamathela, ukumelana nesimo sezulu semvelo nokuvikelwa kwemvelo. Imiphumela yocwaningo ihlinzeka ngesisekelo sethiyori kanye nesiqondiso esisebenzayo sokuthuthukiswa kokusebenza kwama-sealant kanye nokuthuthukiswa kwemikhiqizo emisha, futhi ibaluleke kakhulu ekuthuthukiseni inqubekelaphambili yezobuchwepheshe kanye nentuthuko esimeme yemboni yokupakisha. Ucwaningo lwesikhathi esizayo lungaphinde luhlole izinto ezintsha ezivikela imvelo kanye nezinqubo zokukhiqiza ezihlakaniphile ukuze kuhlangatshezwane nezidingo eziqinile zokuvikela imvelo kanye nezidingo zokupakisha eziqondene nawe.
