Iron core polyurethane caster ke mofuta oa caster e nang le thepa ea polyurethane, e kopantsoeng le mokokotlo oa tšepe, mokokotlo oa tšepe kapa tšepe ea tšepe, e khutsitseng, e liehang ho ba le boima ba 'mele,' me e loketse libaka tse ngata tsa ts'ebetso.
Hangata, boholo ba li-caster tsa indasteri li pakeng tsa 4 ~ 8 inches (100-200mm), le mabili a polyurethane e le a molemo ka ho fetisisa. Mabili a polyurethane a na le khanyetso e phahameng ea abrasion, ts'ebetso e fapaneng e feto-fetohang, mekhoa e fapaneng ea ts'ebetso, ts'ebeliso e pharaletseng, le ho hanyetsa oli, ozone, botsofali, mahlaseli a kotsi, mocheso o tlase, joalo-joalo, molumo o motle oa ho kenella, matla a sekhomaretsi, biocompatibility e ntle haholo. tumellano ya madi.
Li-caster tsa polyurethane li khetholloa haholo ka likarolo tse latelang:
1. Letoto le leholo le feto-fetohang la ts'ebetso. Ka khetho ea lisebelisoa tse tala le ho lokisa foromo, e ka fetoha ka har'a mefuta e mengata ea liphetoho ho matšoao a mangata a 'mele le a mechine, ho finyella litlhoko tse ikhethang tsa mosebedisi mabapi le ts'ebetso ea lihlahisoa. Mohlala, li-elastomer tsa polyurethane li ka etsoa lirolara tsa rabara tse hatisang le lirolara tsa tšepe tse thata ho fihlela litlhoko tsa basebelisi ba fapaneng.
2. Khanyetso e phahameng ea abrasion. Boteng ba metsi, oli le maemo a mang a ts'ebetso ea mecha ea phatlalatso ea ho koloba, ho hanyetsa ha li-polyurethane casters ho makhetlo a 'maloa ho feta a lisebelisoa tse tloaelehileng tsa rabara.
3. Mekhoa e fapaneng ea ts'ebetso le ts'ebeliso e pharaletseng. Polyurethane elastomer e ka bōptjoa ka polasetiki, ho kopanya le ts'ebetso ea vulcanizing (e bua ka MPU); e ka boela ea etsoa rabara e nang le metsi, ho bopa kapa ho fafatsa, ho pitsa le ho bopa ka centrifugal (e bua ka CPU); e ka boela ea etsoa ka thepa ea granular 'me ea bōptjoa ka ente, extrusion, calendering, blow molding le mekhoa e meng (e bua ka CPU).
4. Ho hanyetsa oli, ozone, botsofali, mahlaseli a kotsi, mocheso o tlaase, phetisetso e ntle ea molumo, matla a matla a ho khomarela, biocompatibility e babatsehang le ho lumellana ha mali.
Leha ho le joalo, polyurethane elastomers na le mefokolo e itseng, tse kang mocheso phahameng endogenous, phahameng mocheso ho hanyetsa ka kakaretso, haholo-holo mpe ho hanyetsa mongobo le mocheso, ha e hanyetsane le solvents matla polar le asiti e matla le alkali mecha ea litaba.
