Ensonga ki evudde ku kufuumuuka, okubeerawo kw’ekizigo ekifuumuuka n’engeri gye kiziyizaamu?
Okufuuyira okufuumuuka, era ekimanyiddwa nga okufuuyira, kye kifaananyi nti ekizibu (ekikalu oba amazzi) ekisangibwa munda mu kapiira akatali kavundu oba vulcanizate kitonnya okusenguka kw’engulu. Frosting kizibu kya mutindo gwa bulijjo mu kukola kapiira.
Analysis of causes: 1 The solubility of various additives in rubber is excessively varied. The smaller the solubility of the additives in the rubber is, the more likely it is that excess additives (ie, the content of additives in rubber exceed its solubility in rubber). Causes blooming. When spraying with excessive amounts of cream, the other components are often sprayed together (this phenomenon kiyitibwa passive blooming), wadde nga bino ebikozesebwa mu kukola ebimuli ebitaliiko kye bikola biri wala nnyo okuva ku saturated mu kapiira.
2 Temperature change The solubility of additives in rubber varies with temperature. Under normal circumstances, the solubility is high when the temperature is high, and the solubility is decreased when the temperature is decreased. Since rubber products are usually used at room temperature, once the outside temperature is lower than room temperature, the content of some additives in the formulation will be close to the solubility and precipitated, resulting in blooming. Okugeza, engatto za kapiira ezikolebwa mu biseera eby’obutiti zirina ebisaanyizo mu kiseera ky’okukebera ekkolero, naye zisangibwa nga zifuumuuka mu kiseera ky’obutiti.
. Bwe kitaba ekyo, mu mbeera y’ekibiriiti wansi, omukutu gw’okusalako ogw’omukutu mutono nnyo era emikisa gy’okufuumuuka gyeyongera okusinziira ku ekyo.

(7) Strengthen the management of finished products, packaging, and storage conditions. The finished products should be sealed in plastic bags to prevent aging during contact with sunlight, oxygen, etc. during storage. Avoid storage at low temperatures.
