He mau mea hana like ʻole nā hui rapa i lilo i mea pono ʻole i ka ʻoihana hou. Ma ka hoʻohui ʻana i nā polymers kumu me nā mea hoʻopihapiha, nā plasticizers, nā mea hoʻōla, a me nā mea hoʻohui ʻē aʻe, hiki i nā mea hana ke hoʻopilikino i nā waiwai mechanical, thermal, a me nā kemika e hoʻokō i nā pono kikoʻī. Hoʻokaʻawale nui ʻia nā hui rapa i ʻelua mau māhele nui: rapa maoli (NR) a me ka rapa synthetic. Hoʻokaʻawale hou ʻia nā rapa synthetic i nā ʻano kumu maʻamau a me nā ʻano kūikawā. Hōʻike kēlā me kēia papa i nā ʻano kū hoʻokahi e hoʻoholo ai i kona kūpono no nā ʻoihana like ʻole.
1. Lahopa Kūlohelohe (NR)
Loaʻa mai ka latex o ka lāʻau Hevea brasiliensis, ua mahalo ʻia ka laholio kūlohelohe no kona ikaika tensile koʻikoʻi, ke kūpaʻa i ka haehae, a me ka elasticity. Loaʻa iā ia ke kūpaʻa luhi dynamic maikaʻi loa a me ka hōʻiliʻili wela haʻahaʻa ma lalo o ka ukana cyclic. Eia nō naʻe, ʻaʻole maikaʻi ka pale ʻana o ka NR i nā aila, nā mea hoʻoheheʻe, ka ozone, a me ka radiation UV, a emi iho kona hana i nā mahana kiʻekiʻe.
Nā Hoʻohana: Hoʻohana nui ʻia ka laholio kūlohelohe i nā kaila no nā kaʻa ohua, nā kalaka, a me nā mokulele, ʻoi aku hoʻi ma nā paia ʻaoʻao a me nā hehi kahi e koʻikoʻi ai ka maʻalahi a me ke kūpaʻa. ʻO nā hoʻohana ʻē aʻe e pili ana i nā kāʻei conveyor, nā mea hoʻopau haʻalulu, nā pūnāwai laholio, nā mea hoʻopili, nā mīkina lima latex, nā baluna, a me nā ʻōpae kāmaʻa.
2. Laho Synthetic - Nā ʻAno Hana Laulā
Ua hoʻolālā ʻia nā laholio synthetic no ke kumu maʻamau e pani a hoʻokō paha i ka laholio kūlohelohe i nā noi nui, e hāʻawi ana i ke kūpaʻa maikaʻi aʻe i ka ʻelemakule, ka ʻā ʻana, a i ʻole ka wela.
· Styrene-Butadiene Rubber (SBR): ʻO ka rubber synthetic i hana nui ʻia, hāʻawi ʻo SBR i ke kūpaʻa maikaʻi i ka abrasion, ke kūpaʻa o ka wā ʻelemakule, a me ka paʻa ʻana o ka pulu, ʻoiai he haʻahaʻa kona ikaika tensile a me ka elasticity ma mua o NR. Hoʻomalu ia i ka ʻoihana huila (treads), a me nā kāʻei conveyor, nā hoses, nā gaskets, nā tile papahele, a me nā ʻaoʻao kāmaʻa.
· Polybutadiene Rubber (BR): Me ke kūpaʻa ʻana i ka abrasion, ka hysteresis haʻahaʻa (ka nalowale ikehu haʻahaʻa), a me ke elasticity kiʻekiʻe ʻoiai ma nā mahana haʻahaʻa, hoʻohui pinepine ʻia ʻo BR me NR a i ʻole SBR e hoʻomaikaʻi i ke kūpaʻa ʻana i ka ʻaʻahu. ʻO kāna mau noi e pili ana i nā hehi huila a me nā paia ʻaoʻao, nā pōpō kolepa, nā uhi wili conveyor, a me nā mea hoʻololi hopena no nā plastics.
· ʻO ka Butyl Rubber (IIR): ʻIke ʻia no kona pale ʻana i ka ea a me nā kinoea, i hui pū ʻia me nā waiwai damping maikaʻi a me ke kū'ē ʻana i ka ozone. He mea pono loa ka IIR i loko o nā paipu o loko, nā liners o loko o nā huila, nā ʻōpū hoʻōla, nā mea pani lāʻau lapaʻau, a me nā ʻāpana mask kinoea.
3. Laho Synthetic - Nā ʻAno Kūikawā
Hana ʻia nā laholio kūikawā no nā wahi koʻikoʻi e pili ana i ka wela kiʻekiʻe, nā kemika huhū, ka wahie, a i ʻole ke aniau o waho. Loaʻa iā lākou nā kumukūʻai kiʻekiʻe akā hiki ke hoʻohana i nā noi koʻikoʻi.
· Nitrile Rubber (NBR): Kū'ē maika'i loa i nā aila, nā wahie, a me nā mea ho'ohehe'e i hana 'ia ma ka petroleum, i hui pū 'ia me nā waiwai mechanical maika'i ma kahi ākea o ka mahana (–35°C a i +120°C). 'O NBR ke kūlana no nā hose wahie, nā sila aila, nā O-ring, nā gaskets, nā hose hydraulic, nā mīkina lima no ka lawelawe 'ana i nā kemika, a me nā wili pa'i.
· Chloroprene Rubber (CR - Neoprene): He elastomer kaulike e hāʻawi ana i ke kūpaʻa ʻaila kaulike, ke kū'ē ʻana i ke aniau maikaʻi a me ka ozone, ka pale ʻana i ka lapalapa, a me nā waiwai mechanical paʻa. Hoʻohana nui ʻia ʻo CR i nā kāʻei kaʻa (nā kāʻei manawa a me nā kāʻei serpentine), nā ʻaʻahu kaula, nā wetsuits, nā ʻano hoʻopili, nā bearings alahaka, a me ka wehe ʻana i ke aniau.
· ʻEthylene-Propylene Rubber (EPM/EPDM): Ke kūpaʻa maikaʻi loa i ka wela (a hiki i 150°C), ozone, UV, mahu, a me nā wai polar, akā ʻaʻole kūpono me nā aila a me nā wahie. Hoʻomalu ka EPDM i nā hose ʻōnaehana hoʻoluʻu kaʻa, nā sila o ke aniau, nā membrane o ka hale, nā insulation uila, nā liner loko, a me nā ʻāpana ʻōnaehana brake.
· ʻO ka Silicone Rubber (Q): Me kahi laulā lawelawe mai –60°C a i +230°C (a ʻoi aku paha no nā papa kūikawā), hāʻawi ka silicone rubber i ka maʻalahi maikaʻi loa, ka insulation uila, ka biocompatibility, a me ke kū'ē ʻana i ka hoʻokuʻu ʻana o ka corona. Hoʻohana ʻia ia i loko o nā paipu lapaʻau, nā implants, nā nipples ʻōmole pēpē, nā moena bakena, nā insulators voltage kiʻekiʻe, nā sila aerospace, a me nā pilina keypad.
· Nā Fluoroelastomers (FKM, Viton®): Ke koho premium no ke kūpaʻa kemika a me ka wela koʻikoʻi. Kūpaʻa nā FKM a hiki i ka 250°C mau a kūʻē i nā ʻaila āpau, nā wahie, nā waikawa, a me nā mea hoʻoheheʻe. Hoʻokomo pū ʻia nā noi me nā sila ʻenekini mokulele, nā apo-O o ka ʻōnaehana wahie kaʻa, nā gaskets hale hana kemika, nā lako hana semiconductor, a me nā ʻāpana ʻeli ʻaila.
4. Nā Elastomers Thermoplastic (TPE)
ʻOiai ʻaʻole nā lapu thermoset maʻamau, hoʻohui nā TPE i ka maʻalahi e like me ka laholio me ka hiki ke hana like me ka plastic. Hiki ke hana hou ʻia nā TPE a ʻaʻole pono e hoʻōla. ʻO nā ʻano maʻamau e komo pū me nā styrenic block copolymers (SBS, SEBS) a me nā thermoplastic polyurethanes (TPU). Hoʻohana ʻia lākou i nā lima paʻa palupalu, nā ʻili o loko o ke kaʻa, ka overmolding o nā mea lapaʻau, nā ʻaoʻao kāmaʻa, a me ka insulation wire.
ʻIkepili ʻoihana
· Kaʻa a me ka Halihali: ʻO ka mea kūʻai nui loa o nā hui rubber. ʻO nā kaila (NR, SBR, BR, IIR), nā hose (NBR, EPDM), nā sila (FKM, NBR), nā kāʻei (CR, EPDM), a me nā mauna haʻalulu (NR) e hilinaʻi nei i nā ʻano rubber kikoʻī e hōʻoia i ka palekana, ka pono, a me ke kūpaʻa.
· Hana ʻOihana: ʻO nā kāʻei hoʻoili (NR, SBR), nā wili (NBR, PU), nā gaskets (nā ʻano like ʻole), nā sila hydraulic (TPU, NBR), a me nā pads hoʻokaʻawale haʻalulu (NR) e mālama i nā hale hana a me nā mīkini e holo.
· Aerospace a me ka Pale Kaua: Hoʻohana ʻia nā ʻūpā hana kiʻekiʻe e like me FKM a me silicone no nā sila ʻōnaehana wahie, nā O-ring hydraulic, nā pale wela, a me nā sila kaomi cabin, kahi i hiki ʻole ai ke hāʻule.
· Lapaʻau a me ke Ola Kino: ʻO ka laholio silicone a me ka laholio butyl ka mea nui ma kēia kahua no nā plunger syringe, nā mea pani vial, nā tubing, a me nā kaula hāmeʻa hiki ke hoʻokomo ʻia ma muli o ko lākou biocompatibility a me ka sterilizability.
· Ke Kūkulu ʻana a me nā ʻOihana Hana: ʻO nā membrane uhi hale EPDM, nā gaskets puka makani CR, nā pads bearing bridge NR, a me nā sealant silicone e hāʻawi i ka pale ʻana i ka wā, ka hoʻonui ʻana, a me ke ola lōʻihi i nā hale a me nā papahana ʻenekinia kīwila.
· Nā Waiwai Kūʻai: ʻO nā kapuaʻi wāwae (SBR, BR, TPE), nā waiwai haʻuki (pōpō kolepa, nā peʻa luʻu - NR/CR), nā mīkina lima o ka hale (NR, NBR), a me nā hihia uila (TPE) e hōʻike ana i ka maʻalahi o ka laholio i ke ola o kēlā me kēia lā.
Hopena
ʻO ka hoʻokaʻawale ʻana o nā hui rapa i loko o nā elastomers kūlohelohe, synthetic kumu maʻamau, synthetic kūikawā, a me nā thermoplastic e hōʻike ana i ka laulā o nā koi hana ma nā ʻoihana. Mai ka SBR haʻahaʻa i nā kaila kaʻa a hiki i ka FKM pipiʻi i nā mīkini jet, ʻo kēlā me kēia hui rapa he mea i hana pono ʻia e hāʻawi i ka palekana, ka pono, a me ka hana hou. I ka puka ʻana mai o nā noi hou i nā kaʻa uila, ka ikehu hou, a me ka ʻenehana hiki ke hoʻohana ʻia, e hoʻomau ka hoʻomohala ʻana i nā hui rapa holomua i kahi hana koʻikoʻi i ka ʻepekema mea a me ka ʻenekinia.
