Zovala zochizira bwino za UV zakhala zikugwiritsidwa ntchito popanga pansi, mipando, ndi makabati kwa zaka zambiri. Kwa nthawi yayitali, zokutira zolimba komanso zosungunulira zochokera ku UV zakhala ukadaulo wotsogola pamsika. M'zaka zaposachedwa, ukadaulo wopaka utoto wokhazikika wa UV wakula. Ma resin opangidwa ndi madzi a UV atsimikizira kuti ndi chida chothandiza kwa opanga pazifukwa zosiyanasiyana, kuphatikizapo kudutsa banga la KCMA, kuyezetsa kukana kwa mankhwala, ndi kuchepetsa ma VOC. Kuti ukadaulo uwu upitilize kukula pamsika uno, madalaivala angapo adadziwika kuti ndi madera omwe akufunika kukonza. Izi zidzatenga utomoni wochiritsira wokhala ndi madzi ndi UV kupitilira kungokhala ndi "zoyenera kukhala nazo" zomwe ma resin ambiri amakhala nazo. Adzayamba kuwonjezera zinthu zamtengo wapatali pa zokutira, kubweretsa phindu pamalo aliwonse motsatira unyolo wamtengo wapatali kuchokera ku makina opangira zokutira kupita ku makina opaka fakitale mpaka oyikapo, ndipo pamapeto pake, kwa eni ake.
Opanga, makamaka masiku ano, amalakalaka zokutira zomwe zingachite zambiri kuposa kungopereka zomwe zidanenedwa. Palinso zinthu zina zomwe zimapereka phindu pakupanga, kulongedza, ndi kukhazikitsa. Chimodzi mwazofunikira ndicho kupita patsogolo kwa zomera. Kwa zokutira zokhala ndi madzi izi zikutanthauza kutulutsa madzi mwachangu komanso kutsekereza kukana. Khalidwe lina lomwe mukufuna ndikuwongolera kukhazikika kwa utomoni kuti mugwire / kugwiritsiranso ntchito zokutira, ndikuwongolera zomwe adalemba. Kwa wogwiritsa ntchito ndi woyikirapo, zomwe mukufuna ndizomwe zimawotcha bwino ndipo palibe chizindikiro chachitsulo pakuyika.
Nkhaniyi ifotokoza zakusintha kwaposachedwa kwa ma polyurethanes opangidwa ndi madzi opangidwa ndi UV omwe amapereka utoto wokhazikika wa 50 °C momveka bwino, komanso zokutira zamtundu. Ikukambirananso momwe ma resinswa amalumikizirana ndi zomwe zimafunidwa ndi chopaka utoto powonjezera liwiro la mzere kudzera pakutulutsa madzi mwachangu, kulimba kwa block, komanso kukana kwa zosungunulira pamzere, zomwe zimathandizira kuthamanga kwa ma stacking ndi kulongedza. Izi zithandiziranso kuwonongeka kwapaintaneti komwe kumachitika nthawi zina.

Mawonekedwe amakampani opanga zokutira akusintha nthawi zonse. "Zoyenera kukhala nazo" zongopereka zomwe zanenedwa pamtengo wokwanira pa mil yomwe wagwiritsidwa ntchito sizokwanira. Malo a zokutira zopaka fakitale ku cabinetry, joinery, flooring, ndi furnitures akusintha mwachangu. Opanga omwe amapereka zokutira kumafakitale akufunsidwa kuti apangitse zokutira kuti zikhale zotetezeka kuti ogwira ntchito azigwiritsa ntchito, achotse zinthu zodetsa nkhawa, m'malo mwa VOC ndi madzi, komanso agwiritse ntchito mpweya wocheperako komanso mpweya wambiri wa bio. Chowonadi ndi chakuti nthawi yonseyi yamtengo wapatali, kasitomala aliyense akufunsa zokutira kuti achite zambiri kuposa kungokwaniritsa zomwe akufuna.
Powona mwayi wopanga fakitale yochulukirapo, gulu lathu linayamba kufufuza pamlingo wa fakitale zovuta zomwe ofunsirawa amakumana nazo. Pambuyo pa zokambirana zambiri tidayamba kumva mitu yodziwika bwino:
- Zopinga zololeza zikulepheretsa zolinga zanga zakukulitsa;
- Mitengo ikuchulukirachulukira ndipo ndalama zathu zazikulu zikuchepa;
- Mtengo wa mphamvu ndi ogwira ntchito ukuwonjezeka;
- Kutaya antchito odziwa ntchito;
- Zolinga zathu zamakampani za SG&A, komanso za kasitomala wanga, ziyenera kukwaniritsidwa; ndi
- Mpikisano wakunja.
Mitu iyi idapangitsa kuti mawu amtengo wapatali omwe adayamba kukhudzidwa ndi ogwiritsira ntchito ma polyurethanes ochiritsira a UV opangidwa ndi madzi, makamaka m'malo olumikizirana ndi makabati monga: "opanga ma joinery ndi cabinetry akufuna kukonza magwiridwe antchito a fakitale" ndi "opanga". ndikufuna kukulitsa kupanga pamizere yayifupi yopangira ndikuwonongeka pang'ono chifukwa cha zokutira zomwe zimangotulutsa madzi pang'onopang'ono. ”
Table 1 ikuwonetsa momwe, kwa wopanga zokutira zopangira, kuwongolera kwazinthu zina zokutira ndi mawonekedwe akuthupi kumatsogolera ku magwiridwe antchito omwe amatha kuzindikirika ndi wogwiritsa ntchito.

Mbiri ya UV-Curable Polyurethane Dispersions
M'zaka za m'ma 1990, kugwiritsidwa ntchito kwa malonda a anionic polyurethane dispersions okhala ndi magulu a acrylate omwe amamangiriridwa ku polima anayamba kugwiritsidwa ntchito m'mafakitale.1 Zambiri mwazinthuzi zinali muzopaka, inki, ndi zokutira zamatabwa. Chithunzi 1 chikuwonetsa mawonekedwe amtundu wa PUD yochiritsika ndi UV, kuwonetsa momwe zida zokutirazi zimapangidwira.
CHITHUNZI 1 | Generic acrylate ntchito polyurethane dispersion.3
Monga momwe chithunzi 1 chikusonyezera, UV-curable polyurethane dispersions (UV-curable PUDs) amapangidwa ndi zigawo zomwe zimagwiritsidwa ntchito popanga polyurethane dispersions. Aliphatic diisocyanates amachitidwa ndi ma esters, ma diol, magulu a hydrophilization, ndi zowonjezera zowonjezera zomwe zimagwiritsidwa ntchito popanga polyurethane dispersions. . Kusankha kwazinthu zomwe zimagwiritsidwa ntchito ngati midadada yomangira, komanso kamangidwe ka polima ndi kukonza, kumapangitsa kuti PUD igwire ntchito komanso kuyanika. Zosankhazi muzinthu zowonongeka ndi zowonongeka zidzatsogolera ku ma PUD ochiritsidwa ndi UV omwe angakhale osapanga mafilimu, komanso omwe amapanga mafilimu.
Kupanga filimu, kapena kuyanika monga momwe kumatchulidwira nthawi zambiri, kumapereka mafilimu omangika omwe amakhala owuma mpaka kukhudza pamaso pa UV kuchiritsa. Chifukwa ofunsira akufuna kuchepetsa kuipitsidwa ndi mpweya chifukwa cha tinthu tating'onoting'ono, komanso kufunikira kwachangu popanga, izi zimawumitsidwa mu uvuni ngati njira yopitilira kuchiritsa kwa UV. Chithunzi 2 chikuwonetsa kuyanika ndi kuchiritsa kwa PUD yochiritsika ndi UV.
