Ukubeka kafushane
Leli phepha liqhuba ucwaningo ngokusebenza kahle kokusebenza nokusetshenziswa kweizicabha. Izici ezibalulekile ezithinta ukusebenza kwama-sealants zahlolisiswa ngokuhlaziya ukwakheka, izici nezindawo zohlelo lokusebenza lwe-sealant. Ucwaningo lugxile ekukhethweni nasekusebenzeni kwezikhangiso, ama-substrates kanye nezithasiselo, kanye nokwenza ngcono izinqubo zokukhiqiza. Imiphumela ikhombisile ukuthi amandla anamathela, ukumelana nesimo sezulu semvelo nokuvikelwa kwemvelo kwe-sealant elungisiwe yathuthukiswa kakhulu. Lolu cwaningo luhlinzeka ngesisekelo sethiyori kanye nokuholwa okusebenzayo kokuthuthukiswa kokusebenza kwe-glue yokupakisha kanye nokuthuthukiswa kwemikhiqizo emisha, okubaluleke kakhulu ukukhuthaza ukuthuthukiswa komkhakha wokufaka.

Ukuqalisa
Njengezinto ezisemqoka embonini yanamuhla yokufaka embonini, ukusebenza kokupakisha i-glue kuthinta ngqo ikhwalithi yokupakisha nokuphepha kwezokuthutha. Ngokuthuthuka okusheshayo kwe-e-commerce kanye nezidingo eziqinile zemvelo, izidingo eziphakeme zibekwe phambili ekusebenzeni kweglue. Inhloso yalolu cwaningo ukuthuthukisa ukusebenza okuphelele kwama-sealants ngokwazisa ukwakheka kanye nenqubo yokukhiqiza yama-sealants ukufeza isidingo semakethe.
Eminyakeni yamuva nje, izazi ekhaya nakwamanye amazwe ziye zaqhuba ucwaningo olunzulu ngokupakisha i-glue. Smith et al. wafunda imiphumela yokunamathela okuhlukahlukene ekwenzeni ama-sealants, ngenkathi iqembu likaZhang ligxile ekuthuthukisweni kwama-sealants anobungane bemvelo. Kodwa-ke, ukucwaninga ngokusebenza okuphelele kokusebenza kwe-sealant akulungile. Le ndatshana izoqala ekukhetheni kwezinto zokwenziwa kwezinto zokwakha, ukwakhiwa kwenqubo yokukhiqiza kanye nokuthuthuka kwenqubo yokukhiqiza, futhi ihlole ngezindlela ngokuhlelekile ukuthuthukisa ukusebenza kwe-glue yokupakisha.
I. Ukwakheka kanye nezimpawu zeukupakisha glue
I-sealant ikakhulukazi iqukethe izingxenye ezintathu: ukunamathela, okuphansi kanye nokungeza. Adhesives yizithako eziyinhloko ezinquma izakhiwo zama-sealants, futhi zivame ukutholakala ku-acrylic, irabha kanye ne-silicone. I-substrate imvamisa iyifilimu noma iphepha le-polypropylene, futhi ubukhulu bawo kanye nokwelashwa komhlaba kuzothinta izakhiwo zemishini zetheyipu. Izengezo zifaka phakathi amapulasitiki, ama-filler kanye nama-antioxidants ukuthuthukisa izakhiwo ezithile zetheyipu.
Izakhiwo ze-sealant zihlanganisa ikakhulukazi ukunamathela, ukunamathela kokuqala, ukunamathela, ukumelana nokuvikelwa kwesimo sezulu kanye nokuvikelwa kwemvelo. Amandla ebhondi anquma amandla ahlanganisiwe phakathi kwetheyipu kanye nokunamathela, futhi kuyinkomba ebalulekile yokusebenza kwe-sealant. Insiza yokuqala ithinta amandla okuqala wokunamathela weteyipu, ngenkathi i-viscosity yeteyipu ikhombisa ukuqina kwayo kwesikhathi eside. Ukumelana nesimo sezulu semvelo kufaka phakathi ukumelana okushisa okuphezulu, ukumelana kwezinga lokushisa okuphansi kanye nokumelana komswakama. Ukuvikelwa kwezemvelo kugxile ezingxenyeni ezingokoqobo nezingezinhle ze-tepe tepi, ezihlangabezana nezidingo zentuthuko esimeme zezinto zesimanje zokupakisha.
II. Izindawo zohlelo lokusebenza lwe-sealants
Ama-sealants asetshenziswa kabanzi ekupakisheni ezimbonini ezahlukahlukene. Kwezinto ezifuywayo, ama-sealants anamandla aphezulu asetshenziselwa ukuvikela amabhokisi amakhulu asebekhulile futhi aqinisekise ukuphepha kwezimpahla ezintabeni ezinde. Ukufakelwa kwe-e-commerce kudinga ukuthi ama-sealants anokubonakala okuhle kokuqala futhi abamba ukunamathela ukuze ubhekane nokuhlelwa kaningi nokuphatha. Ensimini yokupakishwa kokudla, kuyadingeka ukusebenzisa ama-sealants anobungane bemvelo ukuqinisekisa ukuphepha kokudla nokuhlanzeka.
Ezindaweni ezikhethekile, ukusetshenziswa kwama-sealants kuyinselele ngokwengeziwe. Isibonelo, ezindaweni ezibandayo ze-Chain Logistics, ukupakisha i-glue kudinga ukuba nokumelana okuhle kakhulu kwezinga lokushisa; Ezindaweni eziphakeme zokushisa nendawo yomswakama, itheyipu iyadingeka ukuba nokumelana okuhle okushisayo. Ngaphezu kwalokho, ezinye izimboni ezikhethekile ezinjenge-elekthronikhi kanye nezindawo zokupakisha ezenza imithi zibeka izidingo eziphakeme ekuvikelweni kwama-elektrostiki kanye nezakhiwo ze-antibacterial zama-sealants. Lezi zicelo ezahlukahlukene zidinga ukushayela okusha okuqhubekayo nokuthuthukiswa kobuchwepheshe be-sealant.
III. Ucwaningo ngokusebenza kahle kokusebenza kwe-sealant
Ukuze uthuthukise ukusebenza okuphelele kwama-sealants, lolu cwaningo lubheka izici ezintathu zokukhethwa kwezinto ezibonakalayo, ukusebenza kahle kwenqubo kanye nenqubo yokukhiqiza. Ekukhetheni izinamathela, izakhiwo zezinto zokwakha ezintathu, i-acrylic nenjoloba kanye ne-silicone, ziqhathaniswa, futhi i-acrylic yayinenzuzo ezakhiweni eziphelele. Ukusebenza kwesikhangiso se-acrylic kwaphinde kwakhiwe ngokulungisa isilinganiso se-monomer kanye nesisindo samangqamuzana.
Ukusebenziseka kalula kwe-substrates kugxile kakhulu ekubumbeni nasekwelashweni komhlaba okuphezulu.Ukuhlolwa kukhombisa ukuthi ifilimu le-polypropylene eliminyene elithambekele lifinyelela ibhalansi engcono kakhulu phakathi kwamandla futhi kukhulisa amandla okubumbana nge ukunamathela. Amapulasitiki wemvelo asetshenziswa esikhundleni sezinto zokwakha ama-petroleum endabuko kaphethiloli, kanti iNano-Sio2 yengezwa ukuthuthukisa ukumelana nokushisa.
Intuthuko yenqubo yokukhiqiza ifaka phakathi ukusebenza kwendlela ye-coating kanye nokulawulwa kwezimo zokwelapha. futhi isikhathi sokwelapha sikhombisile ukuthi ukwelashwa ku-80 ° C imizuzu 3 kuveza ukusebenza okuhle kakhulu.Aba umphumela walezi zindawo, ukumelana nokuqina kwesimo sezulu kwandiswa kakhulu, kanye Ukuphuma kwe-VOC kwehliswe ngo-50%.
IV. Iziphetho
Lolu cwaningo luthuthukise kakhulu ukusebenza kwalo okuphelele ngokwenza kahle ukwakheka kanye nenqubo yokukhiqiza ye-sealant. I-sealant elungiselelwe ifinyelele ezingeni lokuhola embonini ngokuya ngokunamathela, ukumelana nokuvikelwa kwesimo semvelo kanye nokuvikelwa kwemvelo. Imiphumela yocwaningo ihlinzeka ngesisekelo sethiyori kanye nokuholwa okusebenzayo kokuthuthukiswa kokusebenza kwama-sealants kanye nokuthuthukiswa kwemikhiqizo emisha, futhi kubaluleke kakhulu ekuthuthukiseni inqubekela phambili yezobuchwepheshe kanye nokuthuthuka okuqhubekayo komkhakha wezobuchwepheshe. Ucwaningo lwesikhathi esizayo lungaphinde luhlole izinto ezintsha zemvelo kanye nezinqubo zokukhiqiza ezihlakaniphile zokuhlangabezana nezidingo eziqinile zemvelo zokuvikela imvelo nezidingo zokufaka ezenziwe ngezifiso.
