Qingdao Topwell Chemical Materials Co., Ltd.E thehiloe ka 2014, ke mofani oa thepa ea hloahloa ea sebetsanang le lipatlisiso, thekiso le dae e ikhethileng e ikhethileng e amanang le mefuta ea mabone-- Leseli la UV, haufi le lebone la infrared(IR), leseli le bonahalang.
Lihlahisoa tsa rona tsa mantlha li kenyelletsa,
1. UV/IR fluorescent pigment le dae,
2. Thermochromic pigment,
3. Haufi le dae e monyang infrared,
4. Perylene pigment,
5. Blue light absorber
6. Dae ea photochromic le pigment
7.Dae e bonahalang e bobebe e bobebe
Re boetse re fana ka le ho itlhophisa dae le pigment, lidae tsa photochromic bakeng sa lense ea optical le fensetere kapa filimi ea koloi, lidae tse phahameng tsa fluorescent bakeng sa filimi e tala ea ntlo le likarolo tse khethehileng tsa koloi, pigment e telele e khuts'oane ea UV le IR pigment bakeng sa indasteri ea khatiso ea ts'ireletso, haufi le dae e monyang infrared, mochini o monyang khanya o moputsoa, lidae tse sefang, dae e sebetsang ea lik'hemik'hale.
Habohlokoa ka ho fetisisa, re etsa mefuta e fapaneng ea lik'hemik'hale tse ntle le lidae tse khethehileng tse hlophisitsoeng le lits'ebeletso tsa ho kopanya, ha re ntse re le lekunutu ho bareki.
Lihlahisoa tsa rona li rekisoa hantle USA, Jeremane, Fora, Brazil, Japane le linaheng tse ling kapa libakeng tse ling. Re tumme ka boleng bo holimo, litheko tsa tlholisano, mesebetsi ea matsoho ea boemo ba pele, sephutheloana se bolokehileng, le ho fana ka thepa kapele.
Re amohela ka tieo metsoalle e tsoang lefats'eng lohle ho etela k'hamphani ea rona le ho sebelisana le rona motheong oa melemo ea nako e telele.
