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;
Adhezija pamučnog platnenog remena otpornog na visoke temperature je relativno niska, a prianjanje remena otpornog na visoke temperature EP je relativno visoko; vijek trajanja EP remena otpornog na visoke temperature očito je duži od vijeka trajanja remena od pamučnog platna otpornog na visoke temperature.
3. Hot glue stripping method (is it good to remove the glue at one end)?
Ovo je još jedna metoda lijepljenja, ova metoda je također moguća, ali ako koristite ovu metodu, obratite pozornost na sljedeće točke:
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.
Obično, kada je temperatura vulkanizacije viša od kritične temperature vulkanizacije akceleratora i sredstva za vulkanizaciju i ne može postići normalnu temperaturu vulkanizacije, može se primijeniti metoda produljenja vremena vulkanizacije kako bi vulkanizacija gume zadovoljila zahtjeve. Općenito, svaki put kada je temperatura niža od 10 stupnjeva, vrijeme vulkanizacije se produljuje za 2-4 puta. Naravno, iz razloga izvedbe, ne preporučujemo korištenje niskih-temperatura i dugotrajne vulkanizacije.
5. Can core rubbers from different manufacturers be mixed?
Ne preporučuje se miješanje jezgrene gume različitih proizvođača jer je formula jezgrene gume različitih proizvođača različita. U gumi postoji mnogo vrsta spojeva, a neki od njih imaju interaktivne reakcije. U formuli istog proizvođača neće biti spojeva s štetnim interaktivnim reakcijama, ali su formule različitih proizvođača vrlo različite. Kada se koristi, može doći do interaktivnih refleksija spojeva, što će utjecati na učinak upotrebe gumene jezgre.
