Iyo kambani Qingdao Topwell Chemical Materials Co., Ltd.yakavambwa muna 2014, inyanzvi mutengesi ari kuita tsvagiridzo, kutengesa uye yakasarudzika pigment uye dhayi izvo zvine hukama nemhando dzemwenje- UV mwenje, pedyo ne infrared mwenje (IR), inooneka mwenje.
Zvigadzirwa zvedu zvikuru zvinosanganisira,
1. UV/IR fluorescent pigment uye dhayi,
2.Thermochromic pigment,
3. Pedyo ne infrared dhayi inotora,
4.Perylene pigment,
5. Blue light absorber
6. Photochromic dhayi uye pigment
7.Dhayi inooneka yakareruka
Isu tinopawo uye nekugadzirisa idzi dhayi uye pigment, photochromic dhayi yeOptical lens uye hwindo kana firimu remota, madhayi efluorescent egirinhi reimba firimu uye mota dzakakosha zvikamu, refu pfupi UV fluorescent pigment uye IR pigment yekuchengetedza indasitiri yekudhinda, padhuze infrared dhayi, yebhuruu mwenje inonyudza, sefa dhayi, dhayi inoshanda, dhayi yemakemikari.
Chinonyanya kukosha, tinoita akasiyana siyana emakemikari akanaka uye madhayi akasarudzika akagadziridzwa uye masevhisi masevhisi, asi zvakavanzika kune vatengi.
Zvigadzirwa zvedu zvinotengeswa zvakanaka muUSA, Germany, France, Brazil, Japan, nedzimwe nyika kana matunhu. Isu tine mukurumbira wemhando yepamusoro, mitengo yemakwikwi, yekutanga-kirasi craftworks, yakachengeteka pasuru, uye nekukurumidza kuendesa.
Isu tinogamuchira nemoyo wese shamwari kubva pasirese kuti vashanyire kambani yedu uye vashande nesu pahwaro hwenguva refu yekubatsirana.
