Kauwili hiki ke noho ma nā moku'āinaʻelua: raw rubber a cured rubber.

Raw rubber e pili ana i ka'ōpala i hui pūʻia me nā mea hoʻohui likeʻole a me nā mea hoʻopihapiha akā ua loaʻa ʻaʻole naʻe i lalo o ka vulcancization . ^. I kēia manawa, e hōʻike mau ana ka waiwai i nā mea momona kiʻekiʻe akā loaʻa ʻO ka ikaika o ka ikaika a me ka elastity . ^. He mau'āpana o konaʻili a paʻakikī, a lacks i nāʻano hana i koiʻia no nā huahana hope loa.

Cured rubber ,ʻike houʻiaʻo rulchen streeber , ua loaʻa ma hope o ka ʻO ka hopena o Vulcancization , i ka manawa o nāʻano sulfur atoms nā loulou ma waena o nā kaula molecular , e hopena ana i a ʻekolu-dimensional pūnaewele hoʻonohonoho . ^. Hāʻawi kēia hoʻololi i ka waiwai ʻO ka ikaika ikaika, elasticity, pale wela, a me keʻano maʻi.

Rulchen streeber ua hoʻohana nuiʻia i ka hanaʻana i nā mea likeʻole Nā Kūlana Kūlana , e like me ʻO nā patomotive tamping, Ke hoʻololi nei i nā apo, Nā Pahu Kāla , a Nā Kūlana Kūʻai . ^. Mālama kēia mau huahana i nā elasticity maikaʻi loa a me ke kauʻana i ka hana ma lalo nei nā kiʻekiʻe kiʻekiʻe, ke kumu, a iʻole nāʻano kūlohelohe , e hana ana iā lākou nā hana hana kūpono ma nā noi hana.

Hiki ke heluʻiaʻo Rubber e kāna Hoʻohanaʻia i loko o laulā-kumu a ʻO ka'ōpala kūikawā kūikawā:

Laulā-kumu Hoʻohuiʻia Kūlohelohe kūlohelohe (nr), ʻO Butadiene Griber (Br), Styrene-baldiene rubber (sbr) , a Isoprene rubber (ir).

ʻO ka'ōpala kūikawā kūikawā Hoʻohuiʻia Fluurorubber (FKM), Acrylic Rubber (ACM), Clorosulineted polythylene (CSM), Crinricated poyethylone (cpe), Silicone silber (vmq), Polythea Bleas (C BO, ECO) , a Polyurethane Rubber (Pu) . ^. Hoʻohana pinepineʻia kēia mau mea ʻO nā mea hōʻeha a iʻole nā ​​hana kūikawā koi ʻO ka paleʻana i ka pale, ka pale wela, a iʻole ke kū'ēʻana i ke kū'ēʻana , nui ma Nā'āpana'ōpala.

Ma nā'ōlelo o ka hana, raw rubber ai ʻO ka ikaika o kaʻeha, ke kūpaʻa, a me ka hoʻopaʻapaʻaʻana , tiha cured rubber hōʻike i ka E nānā pono, elasticity kiʻekiʻe, a me nā waiwai maikaʻi loa . ^. No laila, vulcanchition ʻo keʻano nui no ka hanaʻana nā kūlana kiʻekiʻe kiʻekiʻe me ke ola lōʻihi a me ka hana kūpono.
