Kas notiek uz silīcija oglekļa stieņu virsmas, kuriem nepieciešama tūlītēja nomaiņa?

Ja uz silīcija oglekļa stieņa virsmas rodas šādi apstākļi, parasti tas nekavējoties jāmaina, lai izvairītos no sildīšanas efekta ietekmes vai pat rada drošības problēmas:
Severe cracks: When a large number of dense or deep cracks appear on the surface of the silicon carbon rod, its structural integrity is destroyed. Continuing to use it may cause the silicon carbon rod to break, making the heating equipment unable to work properly, and may also cause safety accidents such as circuit short circuits.
Obvious wear and deformation: If the surface of the silicon carbon rod is obviously worn, the diameter becomes significantly thinner, or there are deformations such as bending and bulging, the resistance distribution will be uneven, resulting in local overheating, affecting the heating effect and the stability of the equipment, and may even cause local overheating and fire.
Nopietni bojājumi līdz galam: smaga dedzināšana, korozija, krāsas maiņa vai atslābināšana, ja silīcija oglekļa stienis ir savienots ar elektrodu, palielinās kontakta pretestību un izraisīs nopietnu sildīšanu kontakta daļā, kas ne tikai ietekmēs vadītspējas un apkures veiktspēju, bet arī var izraisīt ugunsgrēku vai citas elektriskās kļūmes ., bet arī ugunsgrēku vai citas elektriskās kļūmes ..
Surface peeling or blistering: Large-scale peeling or blistering on the surface of the silicon carbon rod means that the protective coating or base material on its surface has been severely damaged, which will accelerate the oxidation and aging of the silicon carbon rod, reduce its service life, and the peeling debris may cause pollution or other damage to the inside of the heating equipment. Abnormal color: The color of the silicon carbon rod is relatively stable during normal use. If there is an obvious color change on the surface, such as blackening, whitening or yellow spots, and the surface contamination factor is excluded, it may be that the internal structure has changed, resulting in performance degradation, and it is also necessary to consider immediate replacement.
