Ndi Mulingo Uti Wotsimikizira Kuphulika Ndi Wapamwamba, BT5 kapena BT4

Mlingo wotsimikizira kuphulika kwa BT5 umadziwika kuti ndi wapamwamba.

Mayunitsi onse adavotera pamlingo wa IIB. Komabe, Zida za T4 zimakhala ndi malire a kutentha pamwamba pa 135 ° C, pomwe zida za T5 ndizochepera 100°C. Kutsika kwakukulu kwa kutentha kwapamwamba kumasonyeza chitetezo chachikulu. Choncho, zida zogwirizana ndi miyezo ya BT5 zimagwirizananso ndi BT4, koma mmbuyo sikugwira ntchito.
