Rabara yomwe imagwiritsidwa ntchito kwambiri pamawaya ndi zingwe: mphira wachilengedwe

Labala wachilengedwe ndi zinthu zotanuka kwambiri zomwe zimatengedwa kuchokera kumitengo monga mitengo ya rabara. Chifukwa cha njira zosiyanasiyana zopangira, mphira wachilengedwe umagawidwa m'mitundu iwiri: mphira wosuta ndi mphira wa crepe. Rubber wosuta amagwiritsidwa ntchito popangawaya ndi chingwemakampani.

Mapangidwe ndi kapangidwe ka mphira wachilengedwe

Chigawo chachikulu cha mphira wachilengedwe ndi rabara hydrocarbon. Zomwe zimapangidwa ndi rabara ya hydrocarbon ndi isoprene, yokhala ndi mamolekyulu a C5H8.

Makhalidwe

1. Mphamvu zamakina apamwamba. Raba yachilengedwe ndi mphira wa crystalline wokhala ndi ntchito yabwino yodzilimbitsa. Kulimba kwamphamvu kwa mphira koyera kumatha kufika kupitirira 170 kg/cm2.

2 Kuchita bwino kwambiri kwamagetsi amagetsi. Raba wachilengedwe amakhala ndi ntchito yabwino yotchinjiriza magetsi, kukana kwambiri kutsekereza, komanso kutayika pang'ono kwa dielectric.

3. Good elasticity. Pakati pa mphira zonse, mphira wachilengedwe umakhala ndi kusungunuka kwabwino

4. Good kukana kuzizira. Natural mphira mankhwala angagwiritsidwe ntchito pa -50 ℃.

5. Kuchita bwino kwa ndondomeko. Rabara yachilengedwe ndiyosavuta kusakaniza ndi zinthu zophatikizira monga vulcanizers, yosavuta kugwiritsa ntchito ndi rabala iliyonse ndi pulasitiki, yosavuta kuwongolera njirayo, ndikuchita bwino kwavulcanization.

Zoyipa za mphira wachilengedwe ndikuti zimakhala ndi kutentha kochepa, kukana kukalamba kwa okosijeni, kukana kwa ozoni, kukana kwamafuta, komanso kukana zosungunulira, ndipo imatha kuyaka ndipo ili ndi magwero ochepa.
