Sealant Testing kalpui dan thlirletna

Construction, automotive, leh industrial sector-a sealing material pawimawh tak a nih angin sealants-te hnathawh hian project quality leh service life a nghawng nghal vek a ni. Sealant rintlakna tur chuan systematic testing process hmanga evaluation kimchang tak neih a ngai a ni.

1. Sample buatsaih leh Pretreatment

Test hmain sealant sample hi standard specification angin siam tur a ni. Hei hian a tlangpuiin substrate buatsaih (eg, tihfai leh polishing), adhesive mixing (component pahnih hi a zat dik taka inhmeh taka inhmeh tur), leh siam (eg, injection molding emaw coating) te a huam tlangpui. Sample te chu standard environment (temperature 23±2℃, humidity 50±5% RH)-ah hun bituk (eg, darkar 24) chhung cured a ngai a, chu chu hman tak tak dinhmun simulate turin a ni.

2. Taksa thil neih tehna

Hardness Testing: Shore Durometer hmang hian cured sealant chu a hman dan tur a tlin theih nan a khauh leh nem loh tehna a ni.

Tensile Adhesion: Tensile testing machine hmangin sealant leh substrate inkar break-a bond strength leh elongation te chu a displacement laka a resistance tehna atan hman a ni.

Elastic Recovery Rate: Hei hian colloid chu compression hnua deformation atanga a lo harhchhuah theih dan a teh a, hun rei tak-a hman chhunga a fatigue resistance a lantir a ni.

III. Chemical leh Weathering Test neih a ni

Heng test-ah hian temperature resistance (temperature sang/hniam dahkhawm hnua performance inthlak danglamna), tui laka invenna (immersion hnua adhesion retention), leh UV aging testing (hun rei tak-term light exposure avanga yellowing emaw chalking emaw simulating) te a ni. Special application thenkhatah pawh chemical stability test a ngai a, chu chu oil leh solvent resistance te hi a ni.

IV. Thil hlauhawm leh Environment Indicator te

Regulations kaihhnawih (GB 18583 ang chi) angin, volatile organic compound (VOC) content, heavy metal residue, leh formaldehyde emission te chu environment mamawh zawm a nih leh nih loh enfiah thin a ni.

V. Result hrilhfiahna leh Reporting

Test data zawng zawng hi ram pum standard (GB/T 14683 leh ASTM C920 ang chi) emaw industry standard emaw nen khaikhin tur a ni. Test dan, condition leh conclusion te awmna formal report tihchhuah a ni ang a, chu chuan material thlan dan tur scientific basis a pe ang.

He standardized process hmang hian sealant hnathawh dan chu systematic takin a finfiah theih a, chu chuan environment complex takah hun rei tak-a rintlakna a tichiang thei a ni.
