Ku saabsan TPU
Alifbeetada loo yaqaan 'Aliphatic TPUs' waa nooc gaar ah oo ah polyurethane thermoplastic ah oo muujiya iska caabin sare oo UV ah, taasoo ka dhigaysa kuwo ku habboon isticmaalka bannaanka halkaas oo soo-gaadhista qorraxda ee muddada dheer ay tahay walaac.
ASida ku xusan sifooyinka kiimikada ee qaybaha lipid-ka diisocyanate, TPU waxaa loo qaybin karaa kooxo udgoon iyo aliphatic ah. Udgoonku waa TPU-ga ugu badan ee aan isticmaalno (uma adkaysto huruud ama saameyn huruud ah waa mid liidata, maaha heer cunto), aliphatic guud ahaan waa in la sameeyo badeecooyin heer sare ah. Tusaalooyinka waxaa ka mid ah aaladaha caafimaadka, agabka u baahan iska caabbinta huruudka joogtada ah, iwm.
ALiphatic-ga sidoo kale wuxuu u qaybsan yahay polyester/polyeter.
Kala soocidda iska caabbinta huruudaynta: Guud ahaan waxaa la barbar dhigaa kaarka cawlan, oo loo qaybiyay heerar 1-5 ah. Ka dib tijaabada iska caabbinta wasakhda huruudka ah sida Suntest, QUV ama tijaabada kale ee soo-gaadhista qorraxda, isbarbardhig isbeddelka midabka ee muunadda ka hor iyo ka dib baaritaanka, darajada ugu fiican waa 5, taasoo macnaheedu yahay asal ahaan ma jiro isbeddel midab. 3 Kuwa soo socda waa isbeddel midab oo muuqda. Guud ahaan, 4-5, taas oo ah, isbeddel midab oo yar, ayaa buuxiyay inta badan codsiyada TPU. Haddii aadan u baahnayn isbeddel midab, guud ahaan waxaad u baahan tahay inaad isticmaasho TPU aliphatic, taas oo ah, waxa loogu yeero TPU aan huruud ahayn, substrate-ku waa mid aan MDI ahayn, guud ahaan HDI ama H12MDI, iwm., baaritaanka UV-ga muddada dheerna midab ma beddeli doono.

Maareynta iyo Kaydinta
1. Ka fogow neefsashada qiiqa iyo uumiga farsamaynta kulaylka
2. Qalabka maaraynta farsamada ayaa sababi kara sameysanka boodh. Iska ilaali inaad neefsato.
3. Isticmaal farsamooyin saldhig oo habboon marka aad maareynayso badeecadan si aad uga fogaato kharashyada korontada ku shaqeeya.
4. Pellet-ka dhulka yaallaa waxay noqon karaan kuwo simbiriirixan oo sababi kara dhac
Talooyinka kaydinta: Si loo ilaaliyo tayada badeecada, ku kaydi badeecadda meel qabow oo qalalan. Ku hay weel si adag loo xiray.
