ʻO nā huila Rubber, ma ke ʻano he ʻāpana hana nui i nā kaʻina hana e like me ka hoʻouna ʻana, ka calendering, a me ka uhi ʻana, ʻo kā lākou waiwai waiwai e hoʻoholo pololei i ka pololei o ka hana, ka pono, a me ka maikaʻi o ka huahana o nā lako. Hōʻike ʻia kēia ʻatikala i nā waiwai mechanical a me nā hiʻohiʻona kemika o nā mea hoʻoheheʻe koʻikoʻi koʻikoʻi e like me ka rubber maoli, ka nitrile rubber, silicone rubber, a me ka fluorine rubber. Ma ka hoʻohui ʻana i nā koi hoʻohana o nā hiʻohiʻona ʻenehana like ʻole, ʻike hohonu ʻo ia i ke kumu kumu o ke koho ʻana i nā mea, e hāʻawi ana i nā ʻōlelo aʻoaʻo a me nā ʻōlelo kūpono no ke koho ʻenehana i nā kula e like me ka hana mechanical, paʻi a me ka paʻi ʻana, a me ka lole lole a me ka paʻi. E hōʻike i ke kānāwai koʻikoʻi "e hoʻoholo ka mea o nā wili wili i kā lākou noi".
I. Ka Ho'oka'awale 'ana i nā mea waiwai a me nā 'ano hana kumu o nā 'olola Rubber
Hoʻoholo pū ʻia ka hana ʻana o nā wili lāʻau e ka molecular structure o ka rubber base, ke ʻano crosslinking a me ke kumu hoʻohui. He mea koʻikoʻi nā ʻokoʻa hana koʻikoʻi o nā mea nui, e hāʻawi ana i kumu no ka hoʻololi ʻana i ke ʻano
1.Natural rubber (NR) roller
ʻO ka hana kumu: Ka ikaika tensile 20-30MPa, rebound rate> 70%, ke kūpaʻa maikaʻi loa, ka paʻakikī kahakai 50-70A, ka pae wela hana -5 degere a 80 degere.
Nā hiʻohiʻona hana: ʻO ka elasticity maikaʻi a me ka maʻalahi, nā waiwai mechanical dynamic, hiki ke hoʻopaʻa pono i nā haʻalulu puʻuwai, akā maikaʻi ʻole ka pale ʻana i ka aila a me ka pale ozone.
2. ʻO ka huila Nitrile (NBR).
ʻO ka hana kumu: Ka ikaika tensile 15-25MPa, Shore hardness 55-75A, ka nui o ka pehu ʻana i ka ʻaila mineral a me ka ʻaila hydraulic ma lalo o 10%, ka pae wela o ka hana -20 degere a 100 degere.
Nā hiʻohiʻona hana: Loaʻa iā ia ka pale ʻaila a me ke kūpaʻa ʻaʻahu, ka ikaika mekini haʻahaʻa, ke kūpaʻa ikaika i ka media non-polar, akā haʻahaʻa haʻahaʻa haʻahaʻa-kūʻai wela a me ke aniau.
3. ʻO ka huila Silicone (VMQ).
ʻO ka hana kumu: Paʻa kahakai 40-60A, ka pae wela hana -60 degere C a 250 degere C, kūlana kiʻekiʻe a me ka haʻahaʻa haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa friction coefficient, biocompatibility e like me nā kūlana USP Class VI.
Nā hiʻohiʻona hana: He kūʻokoʻa kiʻekiʻe kiʻekiʻe -ka wela o ka wā kahiko a me ka hana insulation, maʻalahi ke hoʻoheheʻe ʻia a ʻaʻole pili i nā mea, akā ʻoi aku ka nāwaliwali o kona ikaika mechanical a me kona pale ʻana ma mua o ka lāʻau maoli a me ka nitrile rubber.
4. ʻO ka huila Fluorine (FKM).
ʻO ka hana kumu: Ka ikaika tensile 15-20MPa, Shore hardness 60-80A, ka pae wela o ka hana -20 degere C a 260 degere C, kūpaʻa i nā waikawa ikaika, alkalis ikaika, nā oxidants ikaika a me ka wahie lele a me nā mea hoʻolaha kino.
Nā hiʻohiʻona hana: He paʻa kemika ikaika loa kona a me ke kūpaʻa kiʻekiʻe -mahana, lōʻihi ke ola o ka lawelawe ʻana, akā ʻoi aku ka kiʻekiʻe o ke kumu kūʻai, a ʻo kona elasticity a me ka hiki ke hoʻoponopono ʻia.
5. ʻO ka huila Chloroprene rubber (CR).
ʻO ka hana kumu: Ka ikaika tensile 25-35MPa, Paʻa kahakai 50-70A, ka pae kūʻē o ka ozone a hiki i ka ASTM D1149 Class A, ka pae wela o ka hana -30 degere C a 100 degere C, helu helu oxygen> 38.
Nā hiʻohiʻona hana: Ke kūpaʻa ʻana o ke aniau, ka pale ʻana i ka lapalapa ahi a me ka pale ʻana i ke kino, ka ikaika mechanical kiʻekiʻe, akā ʻoi aku ka nāwaliwali o ka ʻaila ma mua o ka nitrile rubber.
Ii. Maikaʻi - Hoʻololi i ke ʻano: Hoʻomaʻamaʻa pololei ʻana o nā Rola Rubber
ʻO nā koi no ka mahana, waena, kaomi, friction coefficient, a me nā mea ʻē aʻe o nā wili pahu i nā hiʻohiʻona ʻoihana like ʻole. Pono ke koho mea e hoʻokō i ka hoʻohālikelike pololei o "koi hana -"
1. ʻOihana paʻi a pūʻolo: Ke ʻimi nei i ka hoʻololi ʻana i ka ʻīnika like ʻole a me ka ʻaʻahu -like kūʻē
Nā mea kūpono: ʻO nā wili lāʻau maoli (NR), nā wili nitrile (NBR).
Noi noi: Ma ke kaʻina paʻi, hiki i ka elasticity kiʻekiʻe a me ke kūpaʻa maikaʻi loa o nā wili pahu kūlohelohe e hiki ke hōʻoia i ka hoʻohana ʻana i ka inika like ʻole, e pale aku i nā kiko inika a me ka paʻi ʻole ʻana. No nā hiʻohiʻona kahi e hoʻopili ai nā mea hoʻoheheʻe inika, hiki i ke kūpaʻa ʻaila o nā wili pahu nitrile ke pale i ka mea mai ka pehu a me ka deforming, e hōʻoia i ka pololei o ka paʻi ʻana.
Nā mea hoʻohana maʻamau: ʻO nā lola hoʻoili ʻīnika no nā mīkini paʻi offset, nā ʻōwili kaomi no nā mīkini paʻi gravure, a me nā wili laminating no nā kiʻi ʻoniʻoni.
2. ʻOihana paʻi lole a me ka ʻoihana hoʻoluʻu: Ke kaulike ʻana i ke kūpaʻa wela a me ka -pono hoʻohaumia.
Nā mea kūpono: ʻO nā huila Silicone (VMQ), nā wili chloroprene rubber (CR).
Noi noi: I ke kiʻekiʻe -mahana hoʻonohonoho pae o ka paʻi ʻana a me ke kala ʻana (mahanahana 150-200 degere), hiki i ke kiʻekiʻe -mahanahana kū'ē o silicone rubber rollers hiki ke pale i ka wela wela a me ka deformation, a me ka waiwai non-stick o ka ili i nā fibers e ho'ēmi i ka wili wili. Hana ʻia nā ʻōwili alakaʻi lole o nā lako lole waho i ka rubber neoprene, kahi maikaʻi loa ke kūʻē ʻana i ka wā e pale aku ai i ka haki ʻana o nā kukui ultraviolet a me nā wahi humid, no laila e hoʻolōʻihi i ko lākou ola lawelawe.
Nā noi maʻamau: ʻO ka mīkini hoʻonohonoho lole mīkini paʻi paʻi, ka hoʻoluʻu a me ka hoʻopau ʻana i nā mea hana lole alakaʻi lole, ʻili lole mīkini paʻi lole lole.
3. 'Oihana hana metala: Kū'ē i nā 'aila a me nā kūlana hana ki'eki'e
Mea kūpono: ʻO nā wili Nitrile (NBR), nā wili fluorine (FKM).
Loko noi: I ka hana ʻana i nā pā kila -wili ʻia a me ka pepa aluminika, pono e hoʻopili ʻia nā huila lāʻau me ka ʻaila ʻokiʻoki, nā emulsion a me nā mea hoʻolaha ʻē aʻe. Hiki i ke kū'ē aila o ka lāʻau nitrile ke pale i ka pehu ʻana o nā mea, a i ka manawa like, loaʻa iā ia ka ikaika mechanical e pale aku i ka ʻōwili ʻana i ke kaomi kiʻekiʻe. No ka -mea hana metala kiʻekiʻe e pili ana me nā mea hoʻoheheʻe corrosive, ʻo ke kūpaʻa kemika o nā wili fluororubber e hōʻoiaʻiʻo i ka hana paʻa ma ka pāpaʻi paʻakikī.
Nā mea hoʻohana maʻamau: Kākoʻo i nā ʻōwili no nā wili wili anu metala, nā ʻōwili paʻi no nā mīkini ʻoki pepa aluminika, a me nā ʻōwili alakaʻi no nā mea hoʻoheheʻe pololei.
4. ʻOihana hana meaʻai: E hoʻokō i nā koi palekana a me ka mahana
Mea kūpono: Silicone rubber (VMQ) roller
Noi noi: Ma nā kaʻina hana e like me nā kāʻei conveyor meaʻai, ka calendering biscuit, a me ka uhi kokoleka, hiki i ka biocompatibility o nā wili lāʻau silicone ke pale i ka hoʻohaumia ʻana i ka meaʻai. He kūpono ko lākou kiʻekiʻe-kūʻai wela no ke kiʻekiʻe-kaiapuni wela i ke kaʻina hana (80-150 degere ), a ʻo kā lākou hiʻohiʻona maʻalahi -maʻemaʻe e like me nā kūlana hoʻomaʻemaʻe meaʻai.
Nā mea hoʻohana maʻamau: ʻO nā ʻōwili paʻi no nā kāʻei lawe meaʻai, nā ʻōwili no nā mīkini hana biscuit, nā ʻōwili alakaʻi no nā lako pahu lole.
5. Kahua lako -kiʻekiʻe: Hoʻoponopono i nā pilikia kaiapuni
ʻO nā mea kūpono: nā wili fluororubber (FKM), nā wili pahu silicone kūikawā
Loko noi: Ma nā hiʻohiʻona e like me ka hoʻoili ʻana i nā mea aerospace a me ka hoʻoili ʻana i nā mea i loko o nā moku hoʻoheheʻe kemika, pono nā huila fluororubber e kū i nā wela kiʻekiʻe (-50 degere a 250 degere) a me ka pāpaʻi corrosive ikaika. Hiki i ke kūpaʻa kemika a me ke kūpaʻa kiʻekiʻe o ka fluororubber rollers i nā koi koi. I ka hana semiconductor, ua hana ʻia ka wafer transfer rollers i ka silicone rubber kūikawā, nona ka hoʻomaʻemaʻe kiʻekiʻe a me ka hana insulation hiki ke pale i ka haumia o nā wafers.
Nā mea hoʻohana maʻamau: nā mea hoʻolele e wili ai i nā mea hana wili, nā mea kemika lawe wili, semiconductor wafer transfer rollers.
Iii. Nā Kuʻuna Kuleana a me nā kuhikuhi no ka koho ʻana i nā mea
ʻO ke koho ʻana i nā wili wili e pono e hahai i nā kumu nui ʻekolu o "ka mea nui o ka hana, ka hoʻokō ʻana i ka hana, a me ke koena o ke kumukūʻai" : ʻO ka mua, e wehewehe pono i nā ʻāpana kūlana hana nui e like me ka mahana hana, ka waena pili, a me ka ukana kaomi; ʻO ka lua, e hoʻohālikelike i ka pae pale wela, ka hoʻohālikelike kemika a me nā waiwai mechanical o ka mea e like me nā ʻāpana. ʻO ka hope, ma lalo o ka manaʻo o ka hoʻokō ʻana i nā koi o ka hana, pono e noʻonoʻo ʻia ke kumukūʻai waiwai a me ke kaʻina hana.
I ka wā e hiki mai ana, e kālele ana ka hoʻomohala ʻana i nā mea hoʻoheheʻe ʻōpala i nā ʻaoʻao nui ʻelua: ʻo ka hoʻomaikaʻi ʻana i ke kaiapuni, ka hoʻomohala ʻana i nā substrate hiki ke hoʻohaʻahaʻa ʻia a me nā mea hoʻohui haʻahaʻa -VOC e hōʻemi i ka hopena o ke kaiapuni; ʻO ka lua o ka hoʻohuihui hana. Ma o ka hoʻololi ʻana i ka hui ʻana (e like me ka hoʻohui ʻana i ka nitrile rubber me ka polyvinyl chloride) a i ʻole ka ʻenehana uhi uhi, hiki ke hoʻokō ʻia ka hoʻohui ʻana o nā hana he nui e like me "kū pale ʻaʻahu + pale ʻaila + pale wela" hiki ke hoʻokō, e hoʻonui hou i nā palena noi ma nā kahua hana kiʻekiʻe -hope.
