Mabhenefiti eUV/LED Curing Adhesives

Chikonzero chikuru chekushandisa ma LED curing adhesives panzvimbo pe UV adhesives anorapika ndechipi?

Zvinonamira zve LED zvinoporesa zvinowanzo poresa mumasekonzi 30-45 pasi pechiedza che405 nanometer (nm). Zvinonamira zvechinyakare zvinoporesa chiedza, zvakasiyana, zvinoporesa pasi pechiedza che ultraviolet (UV) zvine marefu ari pakati pe320 ne380 nm. Kune mainjiniya ekugadzira, kugona kuporesa zvinonamira zvizere pasi pechiedza chinoonekwa kunovhura nzira dzakasiyana dzekubatanidza, kufukidza uye kuvhara izvo zvaisambokodzera zvigadzirwa zvechiedza, sezvo mumashandisirwo mazhinji, zvinhu izvi zvingasatapurirana muwavelength yeUV asi zvichibvumira kutapurirana kwechiedza chinoonekwa.

Ndezvipi zvimwe zvezvinhu zvinogona kukanganisa nguva yekurapa chirwere?

Kazhinji, simba rechiedza chemwenje we LED rinofanira kuva pakati pe1 ne4 watts/cm2. Chimwe chinhu chinofanira kufungwa nezvacho idaro kubva parambi kuenda kune rinonamira, semuenzaniso, kana rambi riri kure nerinonamira, nguva yekuchenesa inoreba. Zvimwe zvinhu zvekufunga nezvazvo ihukobvu hwerinonamira, jira rakatetepa rinopora nekukurumidza kupfuura jira rakakora, uye kuti ma substrates acho akajeka sei. Maitiro acho anofanirwa kugadziriswa kuti nguva yekuchenesa ive yakanaka, zvichibva kwete chete pajometri yedhizaini yega yega, asiwo parudzi rwemichina inoshandiswa.

Unoita sei kuti uve nechokwadi chekuti namati ye LED yapora zvizere?

Kana namati ye LED yanyatsogadzirwa, inoumba nzvimbo yakaoma uye isingatsvedzerere inotsvedzerera segirazi. Dambudziko rekare rekuedza kupora pahurefu hwema wavelengths chirwere chinonzi oxygen inhibition. Oxygen inhibition inoitika kana oxygen yemumhepo ikadzivisa maitiro e free-radical polymerization anorapa anenge ma UV adhesives ese. Izvi zvinoguma nenzvimbo yakaoma uye yakatsvedzerera zvishoma.

Kudziviswa kweokisijeni kunonyanya kuonekwa mukushandiswa kusina chipingamupinyi kune okisijeni yemumhepo. Semuenzaniso, kudziviswa kweokisijeni kunowanzova kwakaipa mukushandiswa kwependi yakavharirwa ine mhepo yakavhurika kupfuura mukushandiswa kunoisa namira pakati pegirazi.

Ndezvipi zvimwe zvakanakira kuchengetedzeka kwe LED curating glues vs. UV curating?

Mwenje yeUV inogona kukonzera dambudziko rekuchengetedza sezvo inogona kukonzera kutsva kweganda nekukuvara kwemaziso; kunyangwe mwenje ye LED ichiri kufanira kushandiswa nemidziyo yekudzivirira yakakodzera, inowanzo kusakonzera njodzi yakafanana neyevamwe vayo vanorapa UV.

Ndeapi masisitimu ehunyanzvi anopiwa neMaster Bond ekurapa nemwenje we LED?

Master Bond LED 400 series ine hunhu hwakasiyana-siyana hunodiwa hweinjiniya uye zvichienderana negiredhi rayo, inogona kushandiswa pakubatanidza, kufukidza, uye kuputira. Chigadzirwa chitsva museries iyi iLED405Med.
