Intshayelelo
Njengezinto eziyimfuneko kwishishini lokupakisha lanamhlanje, ukusebenza kweglue yokupakisha kuchaphazela ngokuthe ngqo umgangatho wokupakisha kunye nokhuseleko lokuthutha. Ngophuhliso olukhawulezayo lwe-e-commerce kunye neemfuno ezikhulayo zokusingqongileyo, iimfuno eziphezulu zibekwe phambili ekusebenzeni kweglue yokupakisha. Injongo yolu phononongo kukuphucula ukusebenza okubanzi kwee-sealants ngokulungisa ukubunjwa kunye nenkqubo yokuvelisa izitywini ukuhlangabezana nemfuno yemarike.
Kwiminyaka yakutshanje, abaphengululi basekhaya nakwamanye amazwe baye benza uphando olubanzi ngokupakisha iglu. USmith et al. wafunda imiphumo ye-adhesives eyahlukeneyo ekusebenzeni kwe-sealants, ngelixa iqela likaZhang ligxininise ekuphuhliseni i-sealants ehambelana nokusingqongileyo. Nangona kunjalo, uphando malunga nokulungiswa okubanzi kokusebenza kwe-sealant akwanelanga. Eli nqaku liza kuqala ekukhethweni kwezinto, ukulungiswa kokuqulunqwa kunye nokuphuculwa kwenkqubo yokuvelisa, kunye nokuhlola ngokucwangcisiweyo iindlela zokuphucula ukusebenza kweglue yokupakisha.
I. Ukuqulunqwa kunye neempawu zeukupakisha iglue
I-sealant ikakhulu iqukethe iinxalenye ezintathu: i-adhesive, substrate kunye ne-additive. I-Adhesives yizona zithako eziphambili ezimisela iimpawu ze-sealants, kwaye zifumaneka ngokuqhelekileyo kwi-acrylic, i-rubber kunye ne-silicone. I-substrate ngokuqhelekileyo ifilimu ye-polypropylene okanye iphepha, kwaye ubukhulu bayo kunye nonyango oluphezulu luya kuchaphazela iimpawu zemishini ye-tape. Izongezo zibandakanya iiplastiki, iifayili kunye ne-antioxidants ukuphucula iimpawu ezithile ze-tape.
Iimpawu ze-sealant zibandakanya ukunamathela, ukubambelela kokuqala, ukubambelela, ukuchasana nemozulu yendalo kunye nokukhuselwa kwendalo. Amandla ebhondi amisela amandla okubopha phakathi kwe-tape kunye ne-adhesive, kwaye isalathisi esibalulekileyo sokusebenza kwe-sealant. I-viscosity yokuqala ichaphazela amandla okuqala okubambelela kwi-tape, ngelixa i-viscosity ye-tape ibonisa ukuzinza kwayo kwexesha elide. Ukuchasana nemozulu yendalo kubandakanya ukumelana nobushushu obuphezulu, ukumelana nobushushu obuphantsi kunye nokumelana nokufuma. Ukukhuselwa kokusingqongileyo kugxininise kwiipropati ezichithwayo kunye nezingenabungozi ze-tape tape, ehlangabezana neemfuno zophuhliso oluzinzileyo lwezinto zokupakisha zanamhlanje.
II. Iindawo zokusetyenziswa kwee-sealants
Ii-sealants zisetyenziswa kakhulu ekupakisheni kumashishini ahlukeneyo. Kwi-logistics, ama-sealants anamandla aphezulu asetyenziselwa ukukhusela iibhokisi ezinzima kunye nokuqinisekisa ukhuseleko lwempahla ekuthuthweni okude. Ukupakishwa kwe-E-commerce kufuna ukuba izitywini zibe ne-viscosity yokuqala elungileyo kwaye zibambe ukunamathela ukuze zimelane nokuhlenga-hlengisa rhoqo kunye nokuphatha. Kwintsimi yokupakisha ukutya, kuyimfuneko ukusebenzisa ama-sealants anobungane bendalo ukuqinisekisa ukhuseleko lokutya kunye nococeko.
Kwiindawo ezikhethekileyo, ukusetyenziswa kwee-sealants kunzima kakhulu. Ngokomzekelo, kwi-cold chain logistics, ukupakisha iglue kufuneka ibe nokumelana nokushisa okuphezulu; Kwiindawo zokugcina ukushisa okuphezulu kunye nomswakama, i-tape iyadingeka ukuba ibe nokuchasana kakuhle kwe-thermal. Ukongeza, amanye amashishini akhethekileyo afana nombane kunye nokupakishwa kwamayeza abeka iimfuno eziphezulu kukhuseleko lwe-electrostatic kunye nepropathi yokulwa ne-antibacterial yezitywini. Ezi mfuno zahlukeneyo zosetyenziso ziqhuba ukutsha okuqhubekayo kunye nophuhliso lwetekhnoloji ye-sealant.
III. Uphando malunga nokulungiswa kokusebenza kwe-sealant
Ukuze kuphuculwe ukusebenza okubanzi kwee-sealants, olu pho nonongo lujonga imiba emithathu yokukhethwa kwezinto, ukulungelelaniswa kokuqulunqwa kunye nenkqubo yokuvelisa. Ekukhethweni kwe-adhesives, iipropati zezinto ezintathu, i-acrylic, i-rubber kunye ne-silicone, yafaniswa, kwaye i-acrylic yayinenzuzo kwiipropati ezibanzi. Ukusebenza kwe-adhesive ye-acrylic yaphuculwa ngakumbi ngokulungelelanisa umlinganiselo we-monomer kunye nobunzima be-molecular.
Ukulungelelaniswa kwe-substrates kugxininise kakhulu kubukhulu kunye nonyango olungaphezulu.Uvavanyo lubonisa ukuba ifilimu ye-polypropylene ye-38μm engqingqwa ye-biaxially ifezekisa eyona ndlela ilungileyo phakathi kwamandla kunye neendleko. Iiplasticizers zendalo zisetyenzisiwe endaweni yezinto eziqhelekileyo ezisekelwe kwi-petroleum, kwaye i-nano-SiO2 yongezwa ukuphucula ukuchasana nokufudumala.
Ukuphuculwa kwenkqubo yokuvelisa ibandakanya ukulungiswa kwendlela yokwaleka kunye nokulawulwa kweemeko zokuphilisa. Ukusebenzisa iteknoloji yokugqoka i-micro-gravure, i-coating efanayo ye-adhesive iyafezekiswa, kwaye ubukhulu bulawulwa kwi-20 ± 2 μm. Uphononongo lobushushu kunye nexesha lokunyanga lubonise ukuba ukunyanga kwi-80 ° C kwi-3. i-sealant yandiswe ngama-30%, ukuchasana nemozulu yendalo kwandiswa kakhulu, kwaye ukukhutshwa kwe-VOC kwancitshiswa ngama-50%.
IV. IZIGQIBO
Olu phononongo luphucule kakhulu ukusebenza kwalo olubanzi ngokulungiselela ngokufanelekileyo ukubunjwa kunye nenkqubo yokuvelisa i-sealant. I-sealant ephuculweyo ifikelele kwinqanaba elihamba phambili kwishishini malunga nokubambelela, ukuchasana nemozulu yendalo kunye nokukhuselwa kwendalo. Iziphumo zophando zibonelela ngesiseko sethiyori kunye nesikhokelo esisebenzayo sokuphucula ukusebenza kwezitywina kunye nophuhliso lweemveliso ezintsha, kwaye zibaluleke kakhulu ekukhuthazeni inkqubela phambili yetekhnoloji kunye nophuhliso oluzinzileyo lweshishini lokupakisha. Uphando lwexesha elizayo lunokuphonononga ngakumbi izixhobo ezitsha zokusingqongileyo kunye neenkqubo zokuvelisa ezikrelekrele ukuze kuhlangatyezwane neemfuno ezingqongqo zokukhuselwa kwendalo kunye neemfuno zokupakishwa komntu.
