Kusiyanitsa pakati pa mphira waphika ndikuchiritsa

Labala ikhoza kukhala m'maiko awiri akulu: rait rabara ndi Kuchirikiza mphira.

Rait rabara amatanthauza mphira womwe wasakanikirana ndi zowonjezera zosiyanasiyana komanso mafilimu koma ali osakhala akulcananition . Pakadali pano, zinthuzo zikuwonetsabe chipilala chachikulu koma Mphamvu Yopanda Makina Ndi Elastity . Pamaso pake amakhala owuma komanso omata, ndipo alibe magwiridwe antchito ofunikira pazinthu zomaliza.

Kuchirikiza mphira , omwe amadziwikanso kuti rabara , imapezeka pambuyo pa Chiwopsezo cha Vulcanani , pomwe ma atomu a sulufur Maulalo olumikizirana pakati pa ma unyolo , zomwe zimapangitsa mawonekedwe atatu okhala ndi ma netiweki . Kusintha kumeneku kumapereka zinthuzo Mphamvu zazikuluko, kukwezedwa, kukana kutentha, ndi kukhazikika kwamankhwala.

Rabara imagwiritsidwa ntchito kwambiri pakupanga zosiyana Zophatikiza za mphira , monga mapepala oyenda, Makina mphete zosindikiza, chinsinsi cha chinsinsi , ndipo Ngolo . Izi zimakhala ndi zabwino kwambiri komanso kukhazikika Kutentha kwakukulu, kukakamizidwa, kapena malo a mankhwala , kuwapanga magawo ofunikira ogwira ntchito m'mafakitale.

Rabara amathanso kutchulidwa Kugwiritsa Ntchito mu mphira ndi mphira wapadera:

Mphira zikuphatikiza Rabara wachilengedwe (nr), Buledi (br), Styrene-butadiene rabara (SBR) , ndipo Isoprene rabara (IR).

Mphira wapadera zikuphatikiza Fluorororubber (fkm), Acrylic Hight (ACM), Chlorosulfonal polyethylene (csm), Chlorinated polyethylene (CPE), Silicone mphira (VMQ), Polyther rabara (CO, Eco) , ndipo Polyurethane rabara (pu) . Izi nthawi zambiri zimagwiritsidwa ntchito mkati Asitikali kapena apadera malo zofuna Kukaniza Mafuta, Kukaniza Kutentha, kapena Kukana Kupumula , makamaka mu ziwalo za rabara.

Malinga ndi magwiridwe antchito, rait rabara watero mphamvu yotsika, kulimba, komanso kukanidwa , pomwe Kuchirikiza mphira amawonetsa a Malo osalala, kutalika kwambiri, komanso mphamvu zazikulu . Choncho Vulcananiza ndiye njira yofunika kupanga Zida zapamwamba za mphira Ndi moyo wautumiki wautali komanso ntchito yodalirika.

Labala ikhoza kukhala m’maiko awiri akulu: rait rabara ndi Kuchirikiza mphira.
