Ma àgwà nke PCB ink dị oke mma, n’ụkpụrụ, ọ gaghị ekwe omume ịpụ na nchikota nke isi ihe ndị dị n’elu. Ọdịdị dị mma nke ink bụ ngosipụta zuru oke nke sayensị, ọganihu na nchebe gburugburu ebe obibi nke usoro. A na-egosipụta ya na:

Viscosity bụ mbiri maka viscosity ike. A na-egosipụtakarị site na viscosity, ya bụ, nrụrụ ike nke mmiri na-asọpụta na-ekewa site na gradient ọsọ na ntụzịaka nke oyi akwa, ngalaba mba ụwa bụ Pa / sec (Pa.S) ma ọ bụ milliPascal / sec (mPa.S). Na mmepụta PCB, ọ na-ezo aka na mmiri mmiri nke ink na-emepụta site na ndị agha mpụga.

Mmekọrịta mgbanwe nke ngalaba viscosity:

1Pa. S=10P=1000mPa. S=1000CP=10dpa.s

Plasticity pụtara na mgbe ink megharịrị site na ike mpụga, ọ ka na-ejigide ihe onwunwe ya tupu nrụrụ ya. Plasticity nke ink na-eme ka ọ dịkwuo mma ibipụta akwụkwọ;

The thixotropic (thixotropic) ink bụ gelatinous mgbe guzo, na viscosity na-agbanwe mgbe metụrụ ya. A na-akpọkwa ya thixotropic na mgbochi sagging;

Mmiri (ịkwado) ókè nke ink na-agbasa gburugburu n’okpuru omume nke ike mpụga. Mmiri mmiri bụ ngbanwe nke viscosity, na mmiri mmiri na-ejikọta na plasticity na thixotropy nke ink. Plasticity na thixotropy buru ibu, mmiri mmiri dị ukwuu; mmiri mmiri dị ukwuu, akara ahụ dị mfe ịgbasa. Obere ego, dị mfe ịpụta netting, na-ebute ihe dị n’ichepụta ink, nke a makwaara dị ka netting;

Viscoelasticity na-ezo aka n’ikike nke ink nke a na-akpacha ma gbajie mgbe squeegee kpochapụrụ ink ahụ ịlaghachi ngwa ngwa. A na-achọrọ ka nrụrụ ink na-agba ọsọ ngwa ngwa na ink na-alaghachi ngwa ngwa ka ọ baa uru maka ibipụta;

Akọrọ na-achọ ka ink ahụ kpoo na ihuenyo ka ọ dị nwayọọ dị ka o kwere mee, a na-atụkwa anya na mgbe a na-ebufe ink na mkpụrụ, ngwa ngwa ka mma;

The size nke fineness pigmenti na siri ike ihe ahụ, PCB ink bụ n’ozuzu ihe na-erughị 10μm, na size nke fineness kwesịrị ịbụ ihe na-erughị otu ụzọ n’ụzọ atọ nke ntupu oghere;

Mgbe a na-eji shọvel ink were bulie ink, ogo nke ink filamentous adịghị agbaji mgbe a gbatịa ya ka a na-akpọ eriri. The ink filament dị ogologo, na e nwere ọtụtụ filaments n’elu ink na elu obibi akwụkwọ, nke na-eme ka mkpụrụ na-ebipụta efere ruru unyi na ọbụna enweghị ike ibipụta;

Nghọta na ike izo nke ink

Maka ink PCB, dị ka ojiji na ihe dị iche iche si dị, a na-etinyekwa ihe dị iche iche a chọrọ maka nghọta na ike izo ezo nke ink. N’ikwu okwu n’ozuzu, ink sekit, ink na-eduzi na ink agwa niile chọrọ ike nzuzo dị elu. Ihe mgbochi na-ere ahịa na-agbanwe karịa.

Nguzogide kemịkalụ nke ink

PCB ink nwere ụkpụrụ siri ike maka acid, alkali, nnu na ihe mgbaze dịka ebumnuche eji;

Nguzogide anụ ahụ nke ink

PCB ink ga-ezute nguzogide mpụta nke mpụga, nguzogide ujo, nguzogide igwe, ma zute ihe dị iche iche chọrọ ịrụ ọrụ eletrik;

Nchedo na nchekwa gburugburu ebe obibi nke ink

Achọrọ ink PCB ka ọ bụrụ ihe na-egbu egbu, enweghị isi, enweghị nchekwa yana enyi na gburugburu ebe obibi.

N’elu, anyị achịkọtala njirimara bụ isi nke ink PCB iri na abụọ. N’ime ha, na arụ ọrụ nke mbipụta ihuenyo, nsogbu nke viscosity nwere njikọ chiri anya na onye ọrụ. Viscosity dị ezigbo mkpa maka ịdị nro nke ihuenyo silk. Ya mere, na PCB ink teknuzu akwụkwọ na QC akụkọ, na viscosity na-n’ụzọ doro anya akara, na-egosi n’okpuru ụdị ọnọdụ na ụdị viscosity ule ngwá ọrụ.

N’ime usoro obibi akwụkwọ n’ezie, ọ bụrụ na viscosity nke ink dị oke elu, ọ ga-esi ike ibipụta ya, na akụkụ nke eserese ga-agbaji nke ukwuu. Iji meziwanye mmetụta obibi akwụkwọ, a ga-agbakwunye thinner iji mee ka viscosity mezuo ihe ndị a chọrọ. Mana ọ naghị esiri ike ịchọta na n’ọtụtụ ọnọdụ, iji nweta ezigbo mkpebi (mkpebi), n’agbanyeghị viscosity ị na-eji, ọ ka na-agaghị ekwe omume imezu ya. n’ihi gịnị? Mgbe nyocha nke omimi gasịrị, a chọpụtara na viscosity ink bụ ihe dị mkpa, ma ọ bụghị naanị ya. Enwere ihe ọzọ dị ezigbo mkpa – thixotropy. Ọ na-emetụtakwa izi ezi nke mbipụta.
