KEPERDISP®-639
Kala-baxa caalamiga ah wuxuu si wax ku ool ah u yareeyn karaa viscosity , iyo madowga koollada midabku waa mid aad u wanaagsan marka la shiidi karo midab madow oo madow oo leh qadar sare oo dheeraad ah.
dulmar alaabta
KEPERDISP®-639 waa ujeedo guud oo kala firdhiya polyurethane. Waxay si wax ku ool ah u kala firdhi kartaa midabyo kala duwan oo ku jira hababka xabagta ee kala duwan. Gaar ahaan lagu taliyay in lagu shiido kaarboon madow midab-sare (oo lagu daro sare)
Xogta jirka
1. Walax wax ku ool ah: polyurethane culeyska molecular sare
2. Waxa ku jira: 40± 2%
3.Solvent: Butyl acetate/PMA
Tilmaamaha alaabta
1.Excellent waafaqid, nidaamyada codsiga ballaaran, kala firdhiyey caalamiga ah, kala firdhi karaa inorganic, pigments organic, carbon madow.
2.Excellent saamaynta dhimista viscosity, qaybinta midabka fiican ee midabka.
Gaar ahaan marka la kala firdhiyo dusha sare ee madow ee kaarboonka oo leh qadar sare oo dheeri ah, madowga filimka rinjiga ayaa aad u muuqda, dhalaalkuna waa sarreeyaa iyada oo aan hooska ceeryaamo ah.
Imtixaanka codsiga
Waxaan tijaabinay waxqabadka kala firidhsan ee taxanahan alaabta (KEPERDISP-6463/639/635, B-163, iwm) ee nidaamyada hydroxy-acrylic acid.
Midabkayada kala firdhisan: Phthalein buluug
Tijaabi iyo isbarbardhigga walxaha: hufnaanta kala firdhisan, viscosity, midabaynta midabaynta, daahfurnaanta, awoodda ka-hortagga qulqulka, xasilloonida kaydinta.
Natiijooyinka tijaabada:
Waxtarka kala firdhinta
Qalabka kala firdhiso: shiidida ciid, Fidinta Fikirka: 5 µ
Waqtiga kala firdhisanaanta si fiican: Dhammaan waxay gaadheen ganaaxa shiididda 2 saacadood gudahood.
Viscosity:Xogta faahfaahsan ayaa lagu muujiyay shaxda hoose. Saamaynta dhimista viscosity ee 6468 ayaa waxyar ka wanaagsan, halka kuwa kale ay ku dhow yihiin.
| B-163 | 6468 | 639 | 635 | ||
| Fineness (µm) | 5µm | 5µm | 5µm | 5µm | |
| Viscosity (mPa.s) | 6rpm | 11800 | 11300 | 12200 | 12500 |
| 12rpm | 7550 | 7300 | 8100 | 8150 | |
| 30rpm | 3980 | 3900 | 4420 | 4400 | |
| 60rpm | 2320 | 2290 | 2520 | 2530 | |
3.Storage xasiloonida: Ka dib 15 maalmood ee kaydinta shaabadeeyey in 50 ℃, ganaax of koollada shiidi ma beddeli. Korodhka viscosity waa la mid.
Natiijooyinka imtixaanku waxay muujinayaan in sifooyinka dhamaystiran ee KEPERDISP®-6468 ay aad ugu dhow yihiin B-163 ee hababka hydroxy-acrylic acid. Awoodda dhimista viscosity iyo waxqabadka horumarinta midabka ee 6468 ayaa ka wanaagsan. Fadlan nala soo xiriir si aad u hesho warbixin tijaabo ah oo faahfaahsan.
Qadarka lagu daro
Wadarta cadadka titanium dioxide: 1-5%
Marka la eego wadarta cadadka midabada aan noolaha ahayn: 2-15%
Wadarta guud ee midabada dabiiciga ah: 30-60%
Wadarta cadadka kaarboonka madow 30-150%
Qiyaasta ugu fiican ayaa loo baahan yahay in lagu helo baaritaan
Goobta codsiga
Kala firdhinta midabada aan noolaha ahayn, midabada organic iyo kaarboon-madow ee hababka resin-ka dareeraha ah.
Nolosha shelf iyo baakadaha
1. Nolosha shelf waa laba sano, laga bilaabo taariikhda wax soo saarka. Marka la kaydiyo, weelka waa in si fiican loo xiraa, heerkulkuna waa inuu u dhexeeyaa 0-40 ℃
