Muuqaal

Looxa kaydinta qaboobaha ee poliurethane wuxuu isticmaalaa poliurethane fudud sida walxaha gudaha ee looxa kaydinta qabowga.Faa'iidada poliurethane waa in waxqabadka kuleylka kuleylka uu aad u fiican yahay.Dusha sare ee guddiga kaydinta qabow ee poliurethane wuxuu ka kooban yahay taargooyin bir ah oo midab leh iyo taarikada birta ah.Kala duwanaanta heerkulka weyni waxay keenaysaa fidinta heerkulka, si kaydinta qabowgu u noqoto mid tamar badan badbaadisa, waxay noqon kartaa sida saameeynta kulaylka nooca qaboojiyaha, hoos u dhigista isticmaalka korontada iyo hagaajinta waxtarka qaboojinta.

Doorashada guddiga PU
Guddiga PU waxaa loo habeyn karaa iyadoo loo eegayo shuruudaha macaamiisha ee heerkulka qolka qabow.Dhumucdiisuna waxay u dhaxaysaa 50mm 200mm (50mm, 75mm, 100mm, 120mm, 150mm, 200mm).Sagxadaha kala duwan ayaa la bixiyaa si ay u buuxiyaan shuruudaha fayadhowrka kala duwan iyo shuruudaha alaabta qaboojiyaha (PPGI, SISI, Aluminium Embossed iwm.).

Codsiga

Inta badan loo isticmaalo qalabka qaboojiyaha ee cuntada iyo warshadaha kale: sida qaboojiyaha, qaboojiyaha, kaydinta qaboojiyaha, baabuurta qaboojiyaha, iwm. Xumbada adag ee polyurethane waa alaabta kulaylka ugu fiican ee qalabka qaboojiyaha.
