Ebumnuche nke ọmụmụ a bụ iji kwalite arụmọrụ zuru oke nke sealants site n'ịkwalite nhazi na mmepụta usoro nke sealants iji gboo mkpa ahịa.
N'afọ ndị na-adịbeghị anya, ndị ọkà mmụta nọ n'ụlọ na ná mba ọzọ emeela nchọpụta dị ukwuu banyere mkpọkọ gluu. Smith et al. mụọ mmetụta nke nrapado dị iche iche na arụ ọrụ nke sealants, ebe ndị otu Zhang lekwasịrị anya na mmepe nke ihe mkpuchi gburugburu ebe obibi. Otú ọ dị, nchọpụta na njikarịcha zuru oke nke arụmọrụ sealant ka ezughị oke. Edemede a ga-amalite site na nhọpụta ihe, njikarịcha nhazi na nhazi usoro mmepụta, wee nyochaa usoro nke ọma ụzọ isi melite arụmọrụ nke gluu mkpọ.
I. Ihe mejupụtara na njirimara nkemkpọ gluu
Ihe mkpuchi na-abụkarị akụkụ atọ: nrapado, mkpụrụ na mgbakwunye. Adhesives bụ isi ihe na-ekpebi njirimara nke sealants, a na-ahụkarị ha na acrylic, roba na silicone. Mkpụrụ ahụ na-abụkarị ihe nkiri polypropylene ma ọ bụ akwụkwọ, na oke ya na ọgwụgwọ elu ya ga-emetụta ihe eji arụ ọrụ nke teepu. Ihe mgbakwunye gụnyere plasticizers, fillers na antioxidants iji melite njirimara nke teepu.
Njirimara nke sealant tumadi gụnyere adhesion, mbido mbụ, njide adhesion, iguzogide ihu igwe okike na nchekwa gburugburu ebe obibi. Ike njikọ ahụ na-ekpebi ike njikọ dị n'etiti teepu na nrapado, na ọ bụ ihe dị mkpa na-egosi arụmọrụ nke sealant. Viscosity nke mbụ na-emetụta ikike nkedo mbụ nke teepu ahụ, ebe viscosity nke teepu na-egosipụta nkwụsi ike ya ogologo oge. Nguzogide ihu igwe sitere n'okike na-agụnye nguzogide okpomọkụ dị elu, obere okpomọkụ na-eguzogide mmiri. Nchedo gburugburu ebe obibi na-elekwasị anya na ihe ndị na-emebi emebi na nke na-adịghị egbu egbu nke teepu duct, nke na-emezu ihe ndị chọrọ mmepe na-adịgide adịgide nke ihe nkwakọ ngwaahịa ọgbara ọhụrụ.
II. Ngwa mpaghara nke sealants
A na-eji sealants eme ihe n'ọtụtụ ebe na nkwakọ ngwaahịa na ụlọ ọrụ dị iche iche. Na ngwa ngwa, a na-eji ihe mkpuchi dị elu na-echekwa katọn dị arọ ma hụ na nchekwa nke ngwaahịa na njem dị anya. Nkwakọ ngwaahịa e-azụmahịa chọrọ ka ndị na-emechi ihe nwere ezigbo viscosity mbụ ma jide adhesion iji nagide nhazi na njikwa oge niile. N'ihe gbasara nkwakọ nri, ọ dị mkpa iji akara mkpuchi gburugburu ebe obibi iji hụ na nchekwa nri na ịdị ọcha.
N'ebe ndị pụrụ iche, ntinye nke sealants na-esiri ike karị. Dị ka ihe atụ, na oyi na-atụ yinye lọjistik, mkpọ gluu kwesịrị inwe ezigbo okpomọkụ nguzogide; N'ebe nchekwa dị elu na iru mmiri dị elu, a chọrọ teepu ka ọ nwee ezigbo nguzogide okpomọkụ. Na mgbakwunye, ụfọdụ ụlọ ọrụ pụrụ iche dị ka ngwa elektrọnik na nkwakọ ngwaahịa ọgwụ na-etinye ihe ndị dị elu chọrọ na nchekwa electrostatic na ihe nje antibacterial nke sealants. Ngwa ndị a dị iche iche chọrọ ịkwalite ihe ọhụrụ na mmepe nke teknụzụ sealant.
III. Nnyocha na njikarịcha nke arụmọrụ sealant
Iji meziwanye arụmọrụ zuru oke nke sealants, ọmụmụ a na-eleba anya n'akụkụ atọ nke nhọrọ ihe, nhazi nhazi na usoro mmepụta ihe. Na nhọrọ nke adhesives, a na-atụnyere njirimara nke ihe atọ, acrylic, rubber na silicone, na acrylic nwere uru na njirimara zuru oke. A na-emeziwanye arụmọrụ nke nrapado acrylic site n'ịgbanwe nha monomer na ịdị arọ molecular.
The njikarịcha nke substrates na-elekwasị anya tumadi na ọkpụrụkpụ na elu treatment.The nnwale na-egosi na 38μm oké biaxially gbakwasara polypropylene film enweta ihe kasị mma itule n'etiti ike na cost.The elu electrode ọgwụgwọ budata mma elu ike nke mkpụrụ na enhances ike bonding na nrapado. A na-eji plasticizer eke eme ihe karịa ihe ndị sitere na mmanụ ala, na nano-SiO2 na-agbakwunyere iji kwalite nguzogide ikpo ọkụ.
Ọganihu na usoro mmepụta ihe na-agụnye njikarịcha nke usoro mkpuchi na njikwa nke ọnọdụ ọgwụgwọ. Iji teknụzụ mkpuchi micro-gravure, a na-ahụta ihe mkpuchi edo nke nrapado, na ọkpụrụkpụ a na-achịkwa na 20 ± 2 μm. Nnyocha nke okpomọkụ na oge ọgwụgwọ egosila na ọgwụgwọ na 80 Celsius C maka nkeji 3 na-eme ka arụmọrụ kachasị mma nke adheim pụta. A na-abawanye sealant site na 30%, iguzogide ihu igwe sitere n'okike na-emewanyewanye nke ọma, ma belata ikuku VOC site na 50%.
IV. NKWUBIOKWU
Ọmụmụ ihe a kwalitere arụmọrụ ya zuru oke site n'ịkwalite usoro nhazi na mmepụta nke sealant. The kacha sealant erutela ụlọ ọrụ na-eduga larịị n'ihe banyere adhesion, iguzogide eke weathering na gburugburu ebe obibi nchebe. Nsonaazụ nyocha na-enye ntọala usoro ihe omimi na ntuziaka bara uru maka mmezi arụmọrụ nke sealants na mmepe nke ngwaahịa ọhụrụ, ma dị oke mkpa maka ịkwalite ọganihu teknụzụ na mmepe mmepe nke ụlọ ọrụ nkwakọ ngwaahịa. Nchọpụta ga-eme n'ọdịnihu nwere ike ịga n'ihu ịchọpụta ihe ọhụrụ na-eme enyi gburugburu ebe obibi na usoro mmepụta ọgụgụ isi iji gboo mkpa nchekwa gburugburu ebe obibi siri ike na mkpa nkwakọ ngwaahịa ahaziri iche.
