Ubundi UV-Gukiza Ibifata

Igisekuru gishya cya UV-ikiza silicone na epoxies iragenda ikoreshwa mugukoresha amamodoka na electronics.
Igikorwa cyose mubuzima kirimo gucuruza: Kubona inyungu imwe yishyuye iyindi, kugirango uhuze neza ibikenewe biriho. Iyo ibintu birimo guhuza amajwi menshi, gufunga cyangwa gushushanya, abayikora bishingikiriza kumiti ya UV ikiza kuko itanga ibisabwa kandi igakira vuba (amasegonda 1 kugeza kuri 5 nyuma yumucyo).

Ubucuruzi, ariko, ni uko ibyo bifata (acrylic, silicone na epoxy) bisaba substrate ibonerana kugirango ihuze neza, kandi bitwara amafaranga arenze ayo gufatira gukiza ubundi buryo. Nubwo bimeze bityo ariko, inganda zitabarika mu nganda nyinshi zishimiye ubwo bucuruzi mu myaka mirongo ishize. Ibindi bigo byinshi bizabikora kubwigihe kizaza. Itandukaniro, ariko, nuko injeniyeri zizaba zishobora gukoresha silicone cyangwa epoxy UV-ikiza, nkimwe ishingiye kuri acrylic.

Doug McKinzie, visi perezida w’ibicuruzwa byihariye muri Novagard agira ati: "Nubwo twakoze silicone ya UV ikiza mu myaka icumi ishize cyangwa irenga, mu myaka itatu ishize tugomba kongera ingufu mu kugurisha kugira ngo duhuze isoko." Ibisubizo. Ati: “Ibicuruzwa byacu bya UV bikiza silicone byiyongereyeho 50 ku ijana mu myaka mike ishize. Ibi bizagabanya bamwe, ariko turacyategereje iterambere ryiza mu myaka myinshi iri imbere. ”

Mubakoresha cyane silicone ya UV-ikiza harimo imodoka za OEM, hamwe nabatanga icyiciro cya 1 nicyiciro cya 2. Umwe mu batanga icyiciro cya 2 akoresha kashe ya Loctite SI 5031 kuva Henkel Corp. kugeza kumasafuriya mumazu kubikoresho byo kugenzura feri ya elegitoroniki hamwe na sensor ya tine. Isosiyete ikoresha kandi Loctite SI 5039 kugirango ikore UV-yakize-mu mwanya wa silikoni ya silicone ikikije perimetero ya buri module. Bill Brown, umuyobozi ushinzwe porogaramu zikoreshwa muri Henkel, avuga ko ibicuruzwa byombi birimo irangi rya fluorescent kugira ngo bifashe kugenzura niba ibifatika bihari mu igenzura rya nyuma.

Iri teraniro noneho ryoherezwa kubatanga icyiciro cya 1 cyinjiza ibindi bice byimbere kandi bigahuza PCB na terefone. Igifuniko gishyirwa hejuru ya perimeteri kugirango habeho kashe yangiza ibidukikije ku nteko ya nyuma.

UV-gukiza epoxy yifata nayo ikoreshwa kenshi mubikoresho byimodoka nibikoresha ibikoresho bya elegitoroniki. Impamvu imwe ni uko ibyo bifata, kimwe na silicone, byakozwe muburyo bwihariye kugirango bihuze uburebure bwumurabyo utanga urumuri rwa LED (320 kugeza kuri 550 nanometero), bityo ababikora babona inyungu zose zamatara ya LED, nkubuzima burebure, ubushyuhe buke hamwe nuburyo bworoshye. Indi mpamvu nigiciro gito cyamafaranga yo gukiza UV, bityo bikorohereza ibigo gucuruza kugeza kuri tekinoroji.
