4. Chotsukira cha Polyurethane (CPU) Elastomer Wheel Swivel Caster
Casting polyurethane elastomer (CPU) ndi thermosetting polyurethane elastomer yopangidwa pogwiritsa ntchito njira ya chemical reaction. Mawilo opangidwa pogwiritsa ntchito chipangizochi amateteza nthaka, ndipo ali ndi kukana kwabwino kwambiri kwa kukwawa, kukana dzimbiri ndi kukana kwa UC radiation, komanso kusinthasintha kwakukulu. Komabe, ziyenera kudziwika kuti chipangizochi sichimalimbana ndi madzi otentha, nthunzi, mpweya wonyowa, chinyezi kapena zosungunulira zonunkhira. Kutentha koyenera kuli pakati pa -30℃ ndi +70℃, ndi nthawi yochepa mpaka +90℃ kwa kanthawi kochepa. Kulimba kwa polyurethane elastomer ndikwabwino kwambiri kutentha kozungulira kosakwana -10℃ ndipo kuuma kwake ndi 75°+5° Shore A.
5. Chotsukira cha Polyurethane (CPU) Wheel Swivel Caster
Casting polyurethane (CPU) ndi thermosetting polyurethane elastomer yopangidwa pogwiritsa ntchito mankhwala. Ndi yoyenera kwambiri kugwiritsa ntchito yomwe imafika liwiro lalikulu la 16km/h, ndipo makasitomala amatha kusankha mitundu kutengera zomwe akufuna. Kutentha kwa ntchito kumakhala pakati pa -45℃ ndi +90℃, ndipo kugwiritsidwa ntchito kwakanthawi kochepa kumafika mpaka +90℃.
6. Chotsukira Nayiloni (MC) Wheel Swivel Caster
Nayiloni yopangira zinthu (MC) ndi pulasitiki yopangira zinthu zotenthetsera yomwe imapangidwa pogwiritsa ntchito mankhwala, ndipo nthawi zambiri imakhala yabwino kuposa nayiloni yopangira zinthu zothira. Ili ndi mtundu wachilengedwe ndipo siigwira ntchito kwambiri. Kutentha komwe kumagwiritsidwa ntchito popanga nayiloni ndi pakati pa -45℃ ndi +130℃, ngakhale ndikofunikira kudziwa kuti mphamvu yonyamula zinthu idzachepa kutentha kopitirira +35℃.
7. Chotsukira Mawilo cha Polyurethane (PUE) cha Thovu
Foam polyurethane (PUE), yomwe imadziwikanso kuti microcellular polyurethane, imakhala ndi mphamvu yabwino yotetezera ikagwiritsidwa ntchito pamphamvu komanso kupanikizika kwambiri, chinthu chomwe nthawi zambiri sichipezeka mu pulasitiki kapena zipangizo za rabara.
8.Tayala Lolimba la Mphira
Pamwamba pa gudumu la matayala olimba a rabara amapangidwa pokulunga rabara yapamwamba kwambiri kuzungulira m'mphepete mwa gudumu, kenako n’kuliika pamalo otentha kwambiri. Matayala olimba a rabara amayamwa bwino kwambiri komanso amakana kugwedezeka, amasinthasintha bwino, komanso amateteza nthaka bwino komanso amakana kukokoloka. Mitundu ya matayala olimba a rabara ndi yakuda, imvi kapena imvi yakuda, yokhala ndi kutentha koyenera kwa -45℃ ndi +90℃ komanso kuuma kwa 80°+5°/-10° Shore A.
9. Chotsukira Mawilo a Pneumatic
Ma wheel casters a pneumatic amaphatikizapo matayala a pneumatic ndi matayala a rabara, onse awiri opangidwa pogwiritsa ntchito rabala. Amateteza nthaka, ndipo ndi oyenera kwambiri pa nthaka yoipa. Kutentha koyenera ndi -30℃ ndi +50℃.
10. Chotsukira Mawilo a Mphira Chofewa
Mawilo ofewa a rabara amateteza nthaka, ndipo ndi othandiza kwambiri pa nthaka yoipa. Kutentha koyenera ndi -30℃ ndi +80℃ ndi kuuma kwa 50°+5° Shore A.
11. Chotsukira Mawilo a Rabara Chopangidwa
Ma wheel casters a rabara opangidwa ndi thermoplastic rabara elastomers (TPR), omwe ali ndi cushion yabwino kwambiri komanso mphamvu yoyamwa shock, zomwe zimathandiza kuteteza zida, katundu ndi pansi. Magwiridwe ake ndi abwino kuposa a rock steel core rabara wheel, ndipo ndi abwino kwambiri m'malo omwe ali ndi miyala kapena zitsulo. Kutentha koyenera ndi -45℃ ndi +60℃ ndi kuuma kwa 70°±3° Shore A.
12. Chotsukira Mawilo a Mphira Chopangidwa ndi Antistatic
Chotsukira mawilo a rabara chopangidwa ndi antistatic chimapangidwa ndi thermoplastic rubber elastomer (TPE), ndipo chimakhala ndi mphamvu yolimba. Kutentha komwe kumagwiritsidwa ntchito ndi pakati pa -45℃ ndi +60℃ ndi kuuma kwa 70°±3° Shore A.
13. Chotsukira Chitsulo Chotayira Mawilo
Mawilo opangidwa ndi chitsulo cholimba ndi mawilo opangidwa ndi chitsulo cholimba chotuwa chokhala ndi mphamvu zambiri zonyamulira. Kutentha koyenera kumakhala pakati pa -45℃ ndi +500℃ ndi kuuma kwa 190-230HB.
