Ħin tal-issettjar tal-kolla mdewba bis-sħana

Il - ħin tal - issettjar tal -kolla mdewba bis-sħana refers to the positioning time of the hot melt adhesive and the time required for the adhesive to produce a certain strength during the curing time. The solidification time of kolla mdewba bis-sħana is very important for some adherends with high elasticity and high stress. The curing time is long, the initial strength is insufficient, and the adhesive surface of the adherend will bounce.

 

Il-ħin ta 'solidifikazzjoni huwa affettwat mid-diversi komponenti fit-tidwib sħun u wkoll mit-temperatura ambjentali. Pereżempju, meta x-xama 'tintuża f'komponenti, il-ħin tal-issettjar jista' jitqassar billi tuża xama 'b'kristallinità għolja u punt ta' tidwib għoli, u viċi versa; iktar ma tkun baxxa t-temperatura ambjentali, iktar tkun mgħaġġla d-dissipazzjoni tas-sħana u inqas ikun il-ħin tal-issettjar
