Hōʻike huahana

ʻO nā hui hoʻonui Rubber ua kapa ʻia ʻo ia he ʻāpana pulupulu, ʻāpana pulupulu hiki ke hoʻololi ʻia, compensator pulupulu hiki ke hoʻopaʻi ʻia, nā mea haʻalulu, nā mea hoʻoheheʻe hao, a me nā mea ʻē aʻe. ua vulcanized i ka wela kiʻekiʻe a me ke kaomi kiʻekiʻe a laila hui pū ʻia me kahi flange metala a i ʻole ka lima ʻoluʻolu o kahi hui like.Hiki iā ia ke hōʻemi i ka haʻalulu a me ka walaʻau ma muli o ka elasticity kiʻekiʻe, ke kiʻekiʻe o ka ea permeability, ke kūpaʻa waena, ka pale ʻana i ka wā a me ka pale radiation o ka lāʻau, a hiki ke uku no ka hoʻonui ʻana i ka wela a me ka hoʻohaʻahaʻa anuanu i hoʻololi ʻia e ka hoʻololi wela.Hoʻohana nui ia i nā ʻōnaehana pipeline like ʻole.

ʻano:

He kiʻekiʻe kūloko kūloko, hiki ke kū i ke kaomi kiʻekiʻe, a he hopena deformation elastic maikaʻi.

Pōmaikaʻi:

E ho'ēmi i ka haʻalulu, ka walaʻau a me ka māmā.

Ke kumu:

ʻO ka pilina me nā pumps, valves a me nā mea hana ahi, nā paipu me ka haʻalulu nui, a me nā paipu me nā loli pinepine i ke anu a me ka wela.

Media pili:

ʻO ka wai kai, ka wai maʻemaʻe, ka wai anuanu a me ka wela, ka wai inu, ka wai hoʻoheheʻe hale, ka ʻaila maʻemaʻe, ka ʻaila hinu, ka aila lubricating, ka aila huahana, ka ea, ke kinoea, ka mahu a me ka pauda granular.

Ke ano pili:

ʻO ka maʻamau, loaʻa ke ʻano flange loose (semi seal), ʻano flange paʻa (seal piha), ʻano clamp a me ka pilina pili.

Mea o ka ami hikiwawe pulupulu:

ʻO ke kāpiliami hikiwaweUa haku ʻia ka poepoe me ka paipu kopa me nā ʻāpana he nui o ka lole kaula naylon i ʻoki ʻia a me ka papa ʻōpala waho i loko o ka papa ʻōpala o loko a me ka papa hoʻoikaika.ʻOkoʻa nā mea lāʻau i hoʻohana ʻia e like me nā media like ʻole, e like me ka ʻōpala maoli, ka styrene butadiene rubber, butyl rubber, nitrile rubber, ethylene propylene diene monomer, neoprene rubber, silicone rubber, fluorine rubber, etc. kū'ē, kū'ē alkali, kū'ē'ā'ī, kū'ē abrasion, pale aila, etc.

ʻO ka hoʻokaʻawale kikoʻī ʻana o nā ʻāpana hiki ke hoʻopaʻa ʻia: ʻO ka hui ʻana i ka puʻupuʻu kūpaʻa maikaʻi ʻole, ka hui ʻana i ka ʻakika a me ka alkali kūpaʻa ʻana, ka ʻaila ami ʻaʻaʻa, ka wela wela a me ke poʻo.

Ke hoʻokomo ʻana i ka hui ʻana o ka lāʻau lapaʻau:

Hoʻohana nui ʻia nā hui hoʻonui Rubber i ka hoʻomehana wai ahoʻokomonā paipu hoʻoheheʻe kūlohelohe maoli, ka lako wai a me ka hoʻoheheʻe ʻana a me nā paipu wai kahe, nā paipu pahu hau, nā paipu anti-corrosion, ke kaua ahi a me nā paipu compressor refrigeration, a me nā laboratories, nā keʻena noiʻi ʻepekema, nā moku, nā moku a me nā papahana ʻenehana pipeline e hōʻemi i ka haʻalulu. a me ka walaʻau, offset a me nā ʻano hana mālama a mālama ʻana.E hoʻopaʻa paʻa ʻia ka paipu i loko o ka wai ea a me ka ʻōnaehana hoʻoheheʻe ma ka hui pōpō pālua pālua ma ke kākoʻo, kākoʻo a heleuma paha.

ʻO nā hiʻohiʻona nui o ka hui hoʻonui pāpaʻi EPDM

1. Ke kū ʻana o ka ʻelemakule:EPDM hui lāʻauhe maikaʻi ke kū'ē i ka wā, ke kū'ē ozone, ke kū'ē i ka wela, kaʻakika a me ka alkali, ke kū'ēʻana i ka mahu wai, ka paʻa o ka waihoʻoluʻu, ka hana uila, ka hoʻopihaʻana i kaʻaila a me ka wai wela o ka lumi.

2. ʻO ke kūpaʻa wela kiʻekiʻe: Hiki ke hoʻohana ʻia ka hui ʻōpala EPDM no ka manawa lōʻihi ma 120 ℃, a hiki ke hoʻohana pōkole a i ʻole ma waena o 150 - 200 ℃.He ʻoi aku ka maikaʻi o ka pale ʻana i ka mahu wai a manaʻo ʻia ʻoi aku ka maikaʻi ma mua o kona kūpaʻa wela.

3. Ke kū'ē i ka corrosion: ma muli o ka nele o ka polarity a me ka haʻahaʻa haʻahaʻa o ka ethylene propylene rubber ma ka EPDM rubber joints, he kū'ē maikaʻi ia i nā kinikini polar likeʻole e like me ka waiʻona, ka waikawa, ka alkali, ka oxidant, refrigerant, detergent, holoholona a me ka aila meaʻai, ketone a me ka momona.

4. Elasticity maikaʻi: ʻOi aku ka elasticity o ka hui ʻana o ka EPDM ma mua o ka hui ʻana o ka lāʻau maoli.

Hiki i ka EPDM rubber soft connector ke hiki i ka 150h me ka haki ʻole ma lalo o ke kūlana o 50 pphm ozone concentration a me 30% stretching, me ka pale ʻana i ka wā (hoʻohana i ka pae wela - 40 ℃ - 150 ℃) a me ke kūpaʻa kemika.Ma hope o ka hoʻohui ʻana i ka lapalapa ahi, loaʻa iā ia ka retardancy lapalapa maikaʻi a me ka retardancy lapalapa.Hoʻopili ʻia ka huahana e ka microwave hoʻomau vulcanization i hoʻokahi manawa, me ka maʻalahi a me ka nani o ka ʻili, ʻoi aku ka paʻa o ka hana (a ʻaʻole maʻalahi ke hoʻololi.
