Kodi guluu la UV lili bwino kapena ayi?

Uv glue ndi chiyani?

Mawu akuti "guluu wa UV" nthawi zambiri amatanthauza guluu wopanda mthunzi, yemwe amadziwikanso kuti zomatira zomatira kapena zomatira ku ultraviolet.Guluu wa UV amafunikira kuchiritsa kudzera pakuwunika kwa ultraviolet ndipo atha kugwiritsidwa ntchito pomangirira, kujambula, zokutira, ndi zina.Chidule cha "UV" chimayimira Ultraviolet Rays, omwe ndi ma radiation osawoneka a electromagnetic okhala ndi mafunde oyambira 110 mpaka 400nm.Mfundo yochiritsira popanda mthunzi wa zomatira za UV imakhudza kuyamwa kwa kuwala kwa ultraviolet ndi ma photoinitiators kapena photosensitizers muzinthu, zomwe zimapangitsa kuti pakhale ma radicals aulere kapena ma cations omwe amayambitsa ma polymerization ndi kuyanjanitsa pamasekondi.

 

Guluu wopanda mthunzi: guluu wopanda mthunzi umatchedwanso guluu wa ultraviolet, uyenera kukhala kudzera mu kuwala kwa ultraviolet kupita ku guluu pansi pamaziko a machiritso, ndiye kuti, photosensitizer mu guluu wopanda mthunzi ndi kukhudzana ndi kuwala kwa ultraviolet kudzalumikizana ndi monomer, mongoyerekeza popanda guluu. Kuwala kwa guluu wopanda mthunzi wa ultraviolet sikungachiritse.Kuthamanga kwa machiritso a UV kumapangitsa kuti nthawi yochiritsira ikhale yothamanga kwambiri kuyambira masekondi 10 mpaka 60.Zomatira zopanda mthunzi ziyenera kuunikiridwa ndi kuwala kuti zichiritsidwe, kotero zomatira zopanda mthunzi zomwe zimagwiritsidwa ntchito polumikizana zimatha kumangirizidwa ku zinthu ziwiri zowonekera kapena chimodzi mwazo chiyenera kukhala chowonekera, kuti kuwala kwa ultraviolet kuthe kudutsa ndikuyatsa pa guluu.

 

Makhalidwe a glue a UV

1. Kuteteza chilengedwe/chitetezo

Palibe VOC volatiles, palibe kuipitsa mpweya wozungulira;zomatira zomata ndi zochepa zoletsedwa kapena zoletsedwa mu malamulo a chilengedwe;palibe zosungunulira, otsika kuyaka

2. Yosavuta kugwiritsa ntchito ndikuwongolera kupanga bwino

Kuthamanga kwa machiritso ndikofulumira ndipo kumatha kumalizidwa mumasekondi pang'ono mpaka makumi amasekondi, zomwe zimapindulitsa pamizere yopangira makina ndikuwongolera zokolola zantchito.Pambuyo kuchiritsa, ikhoza kuyang'aniridwa ndikusamutsidwa, kupulumutsa malo.Kuchiritsa kutentha kumapulumutsa mphamvu, monga kupanga zomatira zokhala ndi 1g zochizira kuwala.Mphamvu yofunikira ndi 1% yokha ya zomatira zamadzi zofananira ndi 4% ya zomatira zosungunulira.Itha kugwiritsidwa ntchito pazinthu zomwe sizoyenera kuchiritsa kutentha kwambiri.Mphamvu zomwe zimagwiritsidwa ntchito ndi machiritso a ultraviolet zimatha kupulumutsa 90% poyerekeza ndi utomoni wochiritsa matenthedwe.Zida zochiritsira ndizosavuta ndipo zimangofuna nyali kapena malamba oyendetsa.Kupulumutsa malo;dongosolo la gawo limodzi, palibe kusakaniza kofunikira, kosavuta kugwiritsa ntchito.

3. Kugwirizana

Zida zomwe zimakhudzidwa ndi kutentha, zosungunulira ndi chinyezi zingagwiritsidwe ntchito.

Kuwongolera kuchiritsa, nthawi yodikirira imatha kusinthidwa, kuchuluka kwa machiritso kungasinthidwe.Guluu ukhoza kugwiritsidwa ntchito mobwerezabwereza kwa macurings angapo.nyali ya UV imatha kukhazikitsidwa mosavuta pamzere wopangira womwe ulipo popanda kusintha kwakukulu.

4. Kugwiritsa ntchito mosiyanasiyana komanso kugwirizanitsa bwino

Guluu wa UV uli ndi ntchito zosiyanasiyana ndipo umakhala ndi mgwirizano wabwino kwambiri pakati pa mapulasitiki ndi zida zosiyanasiyana.Zili ndi mphamvu zomangirira kwambiri ndipo zimatha kuswa thupi la pulasitiki popanda kusokoneza poyesa kuwononga.Guluu wa UV ukhoza kukhazikitsidwa mumasekondi pang'ono, ndikufikira mwamphamvu kwambiri mphindi imodzi;

Zimawonekeratu pambuyo pochiritsa, ndipo mankhwalawa sadzakhala achikasu kapena oyera kwa nthawi yayitali.Poyerekeza ndi chikhalidwe pompopompo zomatira kugwirizana, ali ndi ubwino kukana chilengedwe mayeso, palibe whitening, kusinthasintha zabwino, etc. Iwo ali kwambiri kutentha otsika, kutentha kwambiri ndi mkulu chinyezi kukana.
