Handheld UV curing lamp hi ultraviolet (UV) radiation hmanga chemical reaction tichhuaktu hmanrua a ni a, coating, adhesive emaw ink emaw rang taka tidam thei hmanrua a ni. An hnathawh dan bulpui ber chu photochemical reaction a ni: Wavelength bik UV radiation chuan photoinitiator a tichak a, chu chuan material chhunga monomer emaw oligomer emaw te chu polymerize emaw crosslink emaw a siam a, a tawpah chuan solid coating a siam ta a ni.
Heng hmanrua te hian mercury vapor lamp emaw LED light source emaw an hmang tlangpui a, mercury vapor lamp hi UV output efficiency sang tak a neih avangin hman a ni nasa hle. Lamp chhunga mercury vapor kal tlanga current a kal chuan mercury atom te chu high-energy state ah an excited thin. Chumi hnuah ground state-ah an inthlak leh a, UV radiation an pe chhuak a, wavelength chu 365nm (UVA), 385nm, emaw 405nm vel a ni. Heng UV wavelength te hian photoinitiators (benzophenone emaw benzoin ether ang chi) te chu a tichak hle a, chu chuan a ti chhe a, free radicals emaw cations emaw a siam a, chu chuan resin material chu polymerization a ti tan ta a ni.
Handheld UV curing lamp hi portability leh precise control atan siam a ni a, a tam zawkah chuan material hrang hrang curing mamawh ang zela adjustable power output leh exposure time te a awm thin. Entirnan, low-intensity mode hi thin coatings atan a tha a, high-intensity mode erawh chu layer thicker zawkte rang taka tihdam nan hman a ni thung. Chubakah, tunlai LED UV curing lamp te hian hmanlai mercury lamp te chu an thlak nasa hle a, hei hi energy hmang tlem, dam rei tak, leh mercury-free operation vang a ni. Mahse, an wavelength range tawi tak hian photoinitiator system bik a mamawh a ni.
Application process chhung hian operator chuan UV light hian cured tur surface chu a rualin a ti eng a, chu chu shadow emaw light leakage emaw, curing tling lo thlen thei tur a awm loh nan a enfiah tur a ni. Chubakah, UV light hian mihring vun leh mit a tichhe avangin hmanruaah hian himna hmanrua, timed alarm emaw optical filter emaw te pawh a tel fo thin.
A tawi zawngin, kut hmanga UV curing lamp hi UV radiation dik taka control leh thil tihthianghlimna tha tak hmanga tihdamna hmangin electronic assembly, ha siamthatna, leh industrial coatings-ah te hman a ni nasa hle. Technology lama hmasawnna kal zel hian thil siamchhuah leh siamthatna chak tak a tipung a ni.
