Ihe na-akpata na ọgwụgwọ nke ogbenye adhesion nke UV gwọọ agba spraying film

Agba ọgwụgwọ UV bụ ụdị agba mkpuchi gburugburu ebe obibi ndụ ndụ ndụ, nke nwere njirimara nke nghọta dị elu, ike siri ike na nguzogide ọkọ.A na-ejikarị ya eme ihe na plastik ma ọ bụ metal substrate mmanụ ịgba usoro.Ihe pụtara ìhè nke na-emetụta ogo mkpuchi na mkpụrụ na ịgbasa UV bụ agba na-ada, ya bụ, nrapado n'etiti agba agba UV na mkpụrụ adịghị mma.Mgbe ahụ, anyị ga-enyocha ihe na-akpata na ngwọta nke adhesion siri ike site n'akụkụ abụọ nke agba UV na spraying substrate.

Ihe kpatara ihe eji gwọọ agba UV siri ike ịrapara na mkpụrụ:

Site na nyocha nke agba ọgwụgwọ UV, mmetụta nke mkpuchi UV na mkpụrụ ahụ adịghị ike n'ihe banyere ịbanye.N'ịtụle arụmọrụ mgbe ọgwụgwọ gasịrị, viscosity nke usoro resin dị ala dị ala na-abawanye na mmiri na-ebelata, ya mere wetting na ntinye nke mkpụrụ ezughị.Ọzọkwa, mbelata olu nke agba UV n'oge ọgwụgwọ na oge mmeghachi omume ngwa ngwa bụ akụkụ abụọ.Nke mbụ ga-eme ka ọdịiche dị na nrụrụ dị n'etiti mkpuchi na mkpụrụ, si otú a na-emepụta nrụgide n'etiti mkpuchi;Nke ikpeazụ bụ n'ihi mmeghachi omume ngwa ngwa, nke ga-eme ka ọ bụrụ ihe na-adịghị mma nke usoro ihe osise UV.

Site n'echiche nke mkpụrụ nke agba agba UV, ihe mbụ ị ga-aghọta bụ ọrụ nke adhesion.Ike nke ịdị adị ya na-ekpebi ma agba na mkpụrụ nwere ike nweta adhesion iji mepụta mkpuchi siri ike.Ya mere, ebe a anyị ga-ekwu mmetụta nke mkpụrụ polarity, crystallinity, elu ike na ire ụtọ na mkpụrụ n'elu adhesion.Polarity na-adịghị ala ma ọ bụ polarity, dị ka PP rọba, nke siri ike mmanụ, kristal dị elu na ike dị ala, dị ka PA nylon substrate, ebe ire ụtọ na-ewu ewu na igwe anaghị agba nchara.Ya mere, usoro ihe omimi na ihe onwunwe nke mkpụrụ ahụ nwekwara mmetụta dị ukwuu na adhesion.Ya mere, mgbe agba UV nwere ike gbanwee, isi ihe na-edozi nsogbu nke adịghị mma adhesion nke UV agba bụ imeziwanye adhesion n'etiti mkpụrụ na UV agba.

Ụzọ iji kwalite adhesion n'etiti mkpuchi agba UV na mkpụrụ:

Na usoro nke na-edozi adhesion nke UV ọgwụgwọ agba fesa na plastic ma ọ bụ metal elu, a oyi akwa nke static agba na-fesa n'elu nke mkpụrụ Sichuan nrapado ọgwụgwọ gị n'ụlọnga bụ irè ngwọta welie adhesion n'etiti mkpụrụ na UV mkpuchi. .Nke mbụ, onye na-ahụ maka ọgwụgwọ nrapado nwere ike ime ka mkpụrụ osisi ahụ zuru oke.Nke abuo, onye na-ahụ maka ọgwụgwọ ahụ nwere hydrogen bonded free radicals na polar otu dị ka hydroxyl nke mkpụrụ, nke na-eme ka ihe nkiri ahụ dịkwuo ọnụ.N'otu oge ahụ, onye na-ahụ maka ọgwụgwọ nrapado na agba nwekwara ike ịmepụta njikọ kemịkalụ, nke ga-ejikọta elu nke mkpụrụ osisi na mkpuchi UV, ma na-akwalite nguzobe nke nrachi dị elu n'etiti agba UV na mkpụrụ.
