Liphaephe tsa Tšepe tse Entsoeng ka Rabara
Liphaephe tsa tšepe tse nang le rabara li etselitsoe ho sebelisoa lits'ebetsong tse fapaneng tsa ho pompa ka mokhoa o khorofo. Lisebelisoa tse kang ho ntša metsi ka har'a polasi, lipompo tsa khatello e phahameng, mela e melelele ea ho hula, lits'ebetso tsa pompo ea slurry e hlokang matla le liphaephe tsa matla a khoheli. Qetello ka 'ngoe e na le flange e tsitsitseng ea tiiso ea rabara e entsoeng ka vulcanized.
Phaephe ea tšepe e nang le rabara e hanelang ho tsofala le e hanelang ho tsofala e entsoe ka phaephe e tloaelehileng ea tšepe e le thepa ea foreimi 'me e sebelisoa ka thepa e ntle ea rabara e hanelang ho tsofala, e hanelang ho tsofala le e hanelang mocheso e le lera la lesela. E kopantsoe ke theknoloji e ikhethang e nang le sekhomaretsi se sebetsang hantle. E sebelisoa haholo-holo ho tsa tšepe, motlakase, indasteri ea lik'hemik'hale, peterole, mashala, samente le libaka tse ling tsa indasteri. Mosebetsing oa merafo, e sebelisoa haholo tsamaisong ea ho tsamaisa merafo ea merafo, ho tlatsa morao ha morafo oa mashala le masimo a amanang le tsamaiso ea liphaephe. Haholo-holo, phaephe e loketse haholo ho fetisa mocheso o pakeng tsa -50°C le +150°C, e leng se bonolo ho se apara le ho tsofala. Re ka eketsa botenya ba lebota sekhutlong sa phaephe ho latela tlhoko ea moreki, ka hona ra eketsa bophelo ba tšebeletso. Ho sa le joalo, bophelo ba tšebeletso ba phaephe ea tšepe e nang le rabara bo ka fihla lilemo tse 15-40 ka kakaretso. Phaephe e ka potoloha hoo e ka bang likhato tse 90 kamora lilemo tse 6-8 tsa tšebeletso. Nako le nako ha e potoloha e ka eketsa nako ea ho sebeletsa, Phaephe ea tšepe e ka manehoa ka rabara ka makhetlo a mararo ho isa ho a mane, ka hona e fokotsa tšebeliso ea litšenyehelo ho ea pele.
