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;
Tá greamaitheacht crios resistant teocht ard chanbhás an chanbhás cadáis sách íseal, agus tá greamaitheacht crios resistant teocht ard PE sách ard; is léir go bhfuil saol seirbhíse crios resistant teocht ard PE níos faide ná sin an crios resistant teocht ard chanbhás cadáis.
3. Hot glue stripping method (is it good to remove the glue at one end)?
Is modh gluing eile é seo, is féidir an modh seo freisin, ach má úsáideann tú an modh seo, tabhair aird ar na pointí seo a leanas:
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.
De ghnáth, nuair a bhíonn an teocht vulcanization níos airde ná an teocht vulcanization ríthábhachtach den luasaire agus an gníomhaire vulcanizing agus nach féidir leis an teocht gnáth vulcanization a bhaint amach, is féidir an modh chun an t-am vulcanization a shíneadh a ghlacadh chun vulcanization an rubair a chomhlíonadh na ceanglais. Go ginearálta, gach uair a bhíonn an teocht níos ísle ná 10 céim, déantar an t-am vulcanization a shíneadh faoi 2-4 huaire. Ar ndóigh, ar chúiseanna feidhmíochta, ní mholaimid úsáid a bhaint as vulcanization íseal-teocht agus fadtéarmach.
5. Can core rubbers from different manufacturers be mixed?
Ní mholtar croí-rubar a mheascadh ó mhonaróirí éagsúla toisc go bhfuil foirmle an chroí-rubair ó mhonaróirí éagsúla difriúil. Tá go leor cineálacha gníomhairí cumaisc i rubair, agus tá imoibrithe idirghníomhacha ag cuid acu. I bhfoirmle an mhonaróra céanna, ní bheidh aon ghníomhairí cumaisc ann le frithghníomhartha idirghníomhacha díobhálacha, ach tá foirmlí na monaróirí éagsúla an-difriúil. Nuair a úsáidtear é, d'fhéadfadh go mbeadh machnaimh idirghníomhacha de ghníomhairí cumaisc, a dhéanfaidh difear d'éifeacht úsáide croí-rubair.
