Paipu Nylon, Paipu Rubber, Paipu Metala

I kēia manawa, hiki ke hoʻokaʻawale ʻia nā mea pipeline i hoʻohana ʻia i nā kaʻa i ʻekolu mau ʻāpana: ka paipu nylon, ka paipu ʻōpala a me ka paipu metala.ʻO nā paipu nylon maʻamau ka nui o PA6, PA11 a me PA12.ʻO kēia mau mea ʻekolu i hui pū ʻia e like me aliphatic Pa. PA6 a me PA12 nā apo polimerization wehe a ʻo PA11 ka polymerization condensation.

1. Na pomaikai opaipu nylonpenei: ▼ ʻoi aku ka maikaʻi o ka aila kūpaʻa (gasoline, diesel), lubricating aila a me ka momona, a me ka pale kemika.▼ hiki ke pale i ka hopena wela haʻahaʻa: hiki i ka PA11 ke pale i ka hopena haʻahaʻa haʻahaʻa o - 50 ℃ a hiki i ka PA12 ke kū i ka hopena haʻahaʻa haʻahaʻa o - 40 ℃.▼ ākea ākea ākea ākea: ʻo ka pae wela o ka noi ʻana o PA11 he - 40 ~ 125 ℃, a ʻo ke kūlana o PA12 ʻo - 40 ~ 105 ℃.Ma hope o ka ho'āʻo kahiko ma 125 ℃, 1000h, 150 ℃ a me 16h, PA11 paipu he haʻahaʻa haʻahaʻa hopena hopena maikaʻi.▼ kū'ē i ka oxygen a me ka zinc paʻakai ʻino: kūʻē i ka 50% zinc chloride solution no ka ʻoi aku ma mua o 200H.▼ kūʻē i ka waika pākaukau a me ka ozone.▼ he mea lubricating pono'ī me ke kū'ē ha'alulu, ke kū'ē kū'ē, ke kū'ē i ka luhi a me ka helu ha'aha'a.▼ ʻO ka pale ʻana o UV a me ka ʻelemakule o ka lewa: hiki ke hoʻohana ʻia ka pale UV o ka waihoʻoluʻu kūlohelohe PA11 no 2.3-7.6 mau makahiki ma muli o nā wahi like ʻole;Ua hoʻonui ʻia ka mana anti ultraviolet o PA11 ʻeleʻele i ʻehā mau manawa ma hope o ka hoʻohui ʻana i ka anti ultraviolet absorbent.

ʻO ke kaʻina hana o ka paipu nylon: ① kaʻina extrusion ② kaʻina hana ③ kaʻina hui ④ kaʻina ʻike.Laulaha,paipu nylonLoaʻa iā ia nā pōmaikaʻi nui i ka hana i hoʻohālikelike ʻia me ka paipu metala, ʻoiai ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion a me ke kūpaʻa ʻaʻahu i hoʻohālikelike ʻia mepaipu kila kila, ka mea nui i ka ho'ēmiʻana i ke kaumaha o ke kaʻa a me ka uku hana.

2. He nuipaipu pulupulunā hale no ke kaʻa, a ʻo nā hale maʻamau ke ʻano maʻamau, ʻano hoʻoikaika a me ke ʻano i uhi ʻia.

ʻO ka hoʻolālā kumu o ka hose rubber i kēia manawa, ʻo ka mea hoʻohana nui ʻia o ka paipu paipu ma ka mākeke ʻo FKM, NBR, Cr, CSM a me eco: ▼ ʻo ka mahana lawelawe o FKM (fluororubber) he 20 ~ 250 ℃, ka mea i hoʻohana nui ʻia no O- apo, sila aila, papa o loko opaipu wahiea me nā huahana hoʻopaʻa sila ʻē aʻe.▼ ʻO ka mahana lawelawe o NBR (nitrile rubber) he 30 ~ 100 ℃, ka mea i hoʻohana nui ʻia no ka hose rubber, sealing ring a me ka sila aila.▼ ka lawelawe ana wela o Cr (chloroprene pulupulu) mea 45 ~ 100 ℃, ka mea i nui hoʻohana 'ia no ka lipine, hose, uea uhi, pulupulu papa gasket 'puehu uhi, etc. ▼ ka lawelawe wela o CSM (chlorosulfonated polyethylene rubber) he 20 ~ 120 ℃, ka mea maʻamau i hoʻohana ʻia no nā kaila, tape, spark plug sheath, wires, electrical parts, O-rings, door and window sealing strips, etc. ka mea i hoʻohana nui ʻia no ke apo wela, diaphragm, shock pad, rubber hose, etc.

3. He ano paipu paakiki,paipu metalaloaʻa nā pōmaikaʻi o ke kaumaha kaumaha, ke kumu kūʻai kiʻekiʻe a me ka haʻihaʻi maʻalahi.No laila, ʻoi aku ka nui o nā ʻoihana kaʻa e koho e haʻalele i ka hoʻohana ʻana i ka paipu metala.I kēia manawa, ʻoi aku ka maikaʻi o ka paipu alumini metala no ka ʻōnaehana ea.Eia nō naʻe, ʻoi aku ka maikaʻi o ka ikaika tensile, ka pohā a me ke kūpaʻa ʻelemakule o nā paipu metala ma mua o nā paipu nylon a me nā paipu ʻōpala.
