Isingeniso
Njengento ebalulekile embonini yesimanje yokupakisha, ukusebenza kweglue yokupakisha kuthinta ngqo ikhwalithi yokupakisha nokuphepha kwezokuthutha. Ngokuthuthuka okusheshayo kwezentengiselwano ze-e kanye nezidingo zemvelo eziqinile, kuye kwabekwa phambili izidingo eziphakeme zokusebenza kweglue yokupakisha. Inhloso yalolu cwaningo ukuthuthukisa ukusebenza okuphelele kweglue yokupakisha ngokwenza ngcono ukwakheka kanye nenqubo yokukhiqiza yeglue yokupakisha ukuze kuhlangatshezwane nesidingo semakethe.
Eminyakeni yamuva nje, izazi zasekhaya nakwamanye amazwe zenze ucwaningo olunzulu ngeglue yokupakisha. USmith nabanye bafunde imiphumela yezinamathiseli ezahlukene ekusebenzeni kwezinamathiseli, kuyilapho ithimba likaZhang ligxile ekuthuthukisweni kwezinamathiseli ezinobungani nemvelo. Kodwa-ke, ucwaningo mayelana nokwenza ngcono ukusebenza kwezinamathiseli lusanelanga. Lesi sihloko sizoqala ekukhetheni izinto, ukwenza ngcono ukwakheka kanye nokuthuthukiswa kwenqubo yokukhiqiza, futhi sihlole ngokuhlelekile izindlela zokuthuthukisa ukusebenza kweglue yokupakisha.
I. Ukwakheka kanye nezici zeiglu yokupakisha
I-sealant ikakhulukazi yakhiwe izingxenye ezintathu: i-glue, i-substrate kanye ne-additives. Ama-adhesive ayizithako eziyinhloko ezinquma izakhiwo zama-sealant, futhi avame ukutholakala ku-acrylic, irabha kanye ne-silicone. I-substrate ngokuvamile iyifilimu noma iphepha le-polypropylene, futhi ukujiya kwayo kanye nokwelashwa kwayo kwendawo kuzothinta izakhiwo ze-mechanical ze-tape. Izithasiselo zifaka ama-plasticizer, ama-filler kanye nama-antioxidants ukuthuthukisa izakhiwo ezithile ze-tape.
Izakhiwo ze-sealant zifaka phakathi ukunamathela, ukunamathela kokuqala, ukunamathela kokubamba, ukumelana nokuguquguquka kwemvelo kanye nokuvikelwa kwemvelo. Amandla e-bond anquma amandla okubopha phakathi kwetheyiphu kanye ne-glue, futhi iyisibonakaliso esibalulekile sokusebenza kwe-sealant. I-viscosity yokuqala ithinta ikhono lokuqala lokunamathela letheyiphu, kuyilapho i-viscosity yetheyiphu ibonisa ukuzinza kwayo kwesikhathi eside. Ukumelana nokuguquguquka kwemvelo kuhlanganisa ukumelana nokushisa okuphezulu, ukumelana nokushisa okuphansi kanye nokumelana nomswakama. Ukuvikelwa kwemvelo kugxile ezimpahleni ezibolayo nezingenabo ubuthi zetheyiphu ye-duct, ehlangabezana nezidingo zentuthuko esimeme zezinto zokupakisha zesimanje.
II. Izindawo zokusetshenziswa kwezivalo zokuvala
Ama-sealant asetshenziswa kabanzi ekupakisheni ezimbonini ezahlukahlukene. Kwezokuthutha, ama-sealant anamandla aphezulu asetshenziselwa ukubopha amabhokisi anzima nokuqinisekisa ukuphepha kwezimpahla ekuthuthweni okude. Ukupakisha kwe-e-commerce kudinga ukuthi ama-sealant abe ne-viscosity enhle yokuqala futhi abambe ukunamathela ukuze abhekane nokuhlunga nokuphatha njalo. Emkhakheni wokupakisha ukudla, kuyadingeka ukusebenzisa ama-sealant anobungani nemvelo ukuqinisekisa ukuphepha kokudla kanye nenhlanzeko.
Ezindaweni ezikhethekile, ukusetshenziswa kwezithiyo zokuvala kuyinselele kakhulu. Isibonelo, ezindaweni zokuthutha ezibandayo, iglue yokupakisha idinga ukumelana nokushisa okuhle kakhulu; Ezindaweni zokugcina amazinga okushisa aphezulu kanye nomswakama, itheyiphu iyadingeka ukuze imelane nokushisa okuhle. Ngaphezu kwalokho, ezinye izimboni ezikhethekile ezifana ne-elekthronikhi kanye nokupakisha kwemithi zibeka izidingo eziphakeme ekuvikelweni kwe-electrostatic kanye nezakhiwo zokulwa namagciwane zethiyori. Lezi zidingo zokusetshenziswa ezahlukahlukene ziqhuba ukusungula izinto ezintsha okuqhubekayo kanye nentuthuko yobuchwepheshe bethiyori.
III. Ucwaningo mayelana nokwenza ngcono ukusebenza kwe-sealant
Ukuze kuthuthukiswe ukusebenza okubanzi kwama-sealant, lolu cwaningo lubheka izici ezintathu zokukhethwa kwezinto, ukwenza ngcono ukwakheka kanye nenqubo yokukhiqiza. Ekukhetheni ama-adhesive, izakhiwo zezinto ezintathu, i-acrylic, irabha kanye ne-silicone, zaqhathaniswa, kanti i-acrylic yayinenzuzo ngezakhiwo ezibanzi. Ukusebenza kwe-adhesive ye-acrylic kwathuthukiswa kakhulu ngokulungisa isilinganiso se-monomer kanye nesisindo sama-molecule.
Ukwenziwa ngcono kwezingxenye ezingaphansi komhlaba kugxile kakhulu ekujiyeni nasekuphathweni kwendawo. Ukuhlolwa kukhombisa ukuthi ifilimu ye-polypropylene enobukhulu obungu-38μm eqondiswe kabili ifinyelela ibhalansi engcono kakhulu phakathi kwamandla nezindleko. Ukwelashwa kwe-electrode yendawo kuthuthukisa kakhulu amandla ongaphezulu engxenye futhi kuthuthukisa amandla okubopha nge-glue. Kwasetshenziswa ama-plasticizer emvelo esikhundleni sezinto zendabuko ezisekelwe ku-petroleum, kwathi i-nano-SiO2 yengezwa ukuthuthukisa ukumelana nokushisa.
Ukuthuthukiswa kwenqubo yokukhiqiza kufaka phakathi ukwenza ngcono indlela yokumboza kanye nokulawulwa kwezimo zokumboza. Kusetshenziswa ubuchwepheshe bokumboza obuncane, ukumboza okufanayo kwe-glue kuyaqashelwa, futhi ubukhulu bulawulwa ku-20 ± 2 μm. Izifundo zokushisa nesikhathi sokumboza zikhombisile ukuthi ukumboza ku-80 ° C imizuzu emi-3 kuveza ukusebenza okuhle kakhulu. Ngenxa yalokhu kuthuthukiswa, amandla okumboza e-sealant anda ngo-30%, ukumelana nokushisa kwemvelo kwanda kakhulu, kanti ukuphuma kwe-VOC kwancishiswa ngo-50%.
IV. IZIPHETHO
Lolu cwaningo luthuthukise kakhulu ukusebenza kwalo okuphelele ngokwenza ngcono inqubo yokwakheka kanye nokukhiqiza kwe-sealant ngendlela ehlelekile. I-sealant elungiselelwe kahle isifinyelele ezingeni elihamba phambili embonini maqondana nokunamathela, ukumelana nesimo sezulu semvelo kanye nokuvikelwa kwemvelo. Imiphumela yocwaningo inikeza isisekelo semfundiso kanye nesiqondiso esisebenzayo sokuthuthukiswa kokusebenza kwe-sealants kanye nokuthuthukiswa kwemikhiqizo emisha, futhi ibaluleke kakhulu ekukhuthazeni intuthuko yezobuchwepheshe kanye nentuthuko esimeme yomkhakha wokupakisha. Ucwaningo lwesikhathi esizayo lungaqhubeka nokuhlola izinto ezintsha ezinobungani nemvelo kanye nezinqubo zokukhiqiza ezihlakaniphile ukuze kuhlangatshezwane nezidingo zokuvikela imvelo eziqinile kanye nezidingo zokupakisha ezenzelwe wena.
