Shandisa: PPH imvura isina ruvara inopenya uye inonhuhwirira zvakanaka. Haina chepfu uye haikuvadzi nharaunda, inoita kuti ideredze mhedzisiro yependi yeV°C. Sezvo ichishanda zvakanaka, emulsion yemvura yakasiyana-siyana uye machira ekupararira mupendi ye gloss uye semi-gloss inoshanda zvakanyanya. Iine vinyl acetate, acrylic esters, styrene - solvent yakasimba yemhando dzakasiyana dze acrylate polymer, diki inonyungudika mumvura (isingasviki mwero wemvura inobuda, inobatsira zvidimbu zvakazvimba), kuti ive nechokwadi chekuti inonyudzwa zvizere nezvidimbu zve latex, yakaumbwa firimu re coating rinoenderera mberi rakanaka kuti ripe latex coalescence kushanda zvakanaka uye kukura kwemavara, asiwo ine kugadzikana kwakanaka kwekuchengetedza. Zvichienzaniswa nezvimwe zvinowedzera kugadzira mafirimu zvakaita seTEXANOL (alcohol ester yakagadzirwa kumba ndeye -12), yakagadzirwa zvizere mufirimu, gloss imwechete, fluidity, anti-sagging, kukura kwemavara, pasi pekukwesha nezvimwe zvinhu, PPH inoderedza huwandu hweinenge 30-50%. Kugona kwakasimba kwe coalescence, kushanda kwakabatana kwe deposition ka1.5-2, mitengo yekugadzira yakadzikira zvakanyanya. Kune akawanda emulsions, PPH yakawedzera mu emulsion huwandu hwe3.5-5%, tembiricha shoma yekugadzira firimu (MFT) inosvika -1°C.
Chipimo chemushonga:
1. Zvinokurudzirwa kuti uise PPH usati waisa emulsion, kana kuisa muchikamu chekukuya pigment, kuitira kuti PPH formulations nezvimwe zvinhu zvive nyore kubatanidza, zviri nani kuti isanganiswe uye iparadzwe, uye nokudaro haizokanganisi kugadzikana kwepigment nezvimwe zvakafanana.
2. Kazhinji, huwandu hwekuwedzera hwe3.5 kusvika 6% acrylic emulsion, acrylic emulsion yevhiniga yakawedzerwa muhuwandu hwe2.5-4.5% yestyrene-acrylic kazhinji 2-4%.
Pasuru:200 kg /madhiramu kana 25 kg /madhiramu epurasitiki uye zvichienderana nezvinodiwa nevatengi.
Kuchengetedza:Chigadzirwa ichi hachina njodzi, chinofanira kuchengetwa munzvimbo inotonhorera uye yakaoma.
