Environmentally friendly white latex must first have sufficient bonding strength, so as to ensure that the bonding will not affect the quality of paper products. To judge whether the bonding strength of environmentally friendly white latex is qualified, two pieces of bonded material can be torn apart along the bonding interface. If the bonding material is damaged after tearing, it proves that the bonding strength is sufficient; if only the bonding interface is separated, it indicates that the strength of environmentally friendly white latex is insufficient. Sometimes environmental friendly white latex with poor performance will degum and brittle film after storage at high temperature or low temperature for a period of time. Therefore, it is necessary to do high temperature and low temperature brittle test to determine whether its quality is reliable.
