1. The longitudinal tear in the middle of the steel belt is 14-15 meters, how to repair it?
The upper and lower covering glue of the damaged part can be peeled off (the length exceeds the damaged part by 50-100mm, and the width exceeds the damaged part by 30-50mm), and at the same time, take a piece of rubber with the same size as the peeled part (preferably with a layer of cloth), and then It can be repaired according to the cold glue method.
2. Comparison of EP high temperature resistant belt and cotton canvas high temperature resistant belt:
a. The same point: the surface covering glue is the same.
b. Differences: cotton canvas can withstand a maximum temperature of 150 degree ; EP-TNG canvas can be used for a long time at 200 degree , and can be used at a maximum of 220 degree ;
The strength of cotton canvas is relatively low, only 50N/mm; while the strength of EP-TNG canvas is relatively high, and the commonly used type 200 is 200N/mm;
Adhesion nan senti koton twal ki reziste tanperati a se relativman ba, ak adezyon nan senti a ki reziste tanperati ki wo EP se relativman wo; lavi sa a ki sèvis EP segondè tanperati ki reziste senti a se evidamman pi long pase sa yo ki nan twal la koton senti tanperati ki reziste.
3. Hot glue stripping method (is it good to remove the glue at one end)?
Sa a se yon lòt metòd kole, metòd sa a posib tou, men si ou itilize metòd sa a, peye atansyon sou pwen sa yo:
a. Be sure to use sealing glue;
b. The parts where the edge rubber parts meet must be connected by vulcanized rubber;
c. The parts where the rubber is connected must be polished
The disadvantage is that the edge glue part is easily damaged if it is not handled properly.
4. The joint temperature reaches 120 degree , but does not reach the normal vulcanization temperature?
no. The normal vulcanization and crosslinking temperature of rubber is determined by the vulcanizing agent and accelerator in the rubber. In order to ensure the safety of rubber processing, the general manufacturer will not set the vulcanization starting temperature of the rubber used in the conveyor belt to be very low. Therefore, when the temperature reaches 120 degree , the rubber will not enter the normal vulcanization state. Therefore, at 120 degree , the quality of the conveyor belt joint will be greatly affected.
Anjeneral, lè tanperati vulkanizasyon an pi wo pase tanperati vulkanizasyon kritik akseleratè a ak ajan vulkanize epi li pa ka rive nan tanperati vulkanizasyon nòmal, yo ka adopte metòd pou pwolonje tan vulkanizasyon an pou fè vulkanizasyon kawotchou a satisfè kondisyon yo. Anjeneral, chak fwa tanperati a pi ba pase 10 degre, tan vulkanizasyon an pwolonje pa 2-4 fwa. Natirèlman, pou rezon pèfòmans, nou pa rekòmande pou sèvi ak ba -tanperati ak vulkanizasyon alontèm.
5. Can core rubbers from different manufacturers be mixed?
Li pa rekòmande pou melanje nwayo kawotchou ki soti nan diferan manifaktirè paske fòmil la nan nwayo kawotchou ki soti nan diferan manifaktirè diferan. Gen plizyè kalite ajan konpoze nan kawotchou, ak kèk nan yo gen reyaksyon entèaktif. Nan fòmil la nan menm manifakti a, pa pral gen okenn ajan konpoze ak reyaksyon negatif entèaktif, men fòmil yo nan manifaktirè diferan yo trè diferan. Lè yo itilize, ka gen refleksyon entèaktif nan ajan konpoze, ki pral afekte efè a itilize nan kawotchou nwayo.
