HDPEbellows, i kapa ʻia ʻo PE curragted pipe, he ʻano hou o ka paipu māmā i hana ʻia me ka polyethylene kiʻekiʻe kiʻekiʻe. Loaʻa iā ia nā ʻano o ke kaumaha māmā, ke kūpaʻa kiʻekiʻe, ka paʻakikī maikaʻi, ke kūkulu wikiwiki ʻana a me ke ola lōʻihi.

ʻO ke anawaena o nā bellows pālua HDPE i hana ʻia ma Kina ʻo φ400 ~ φ1400mm, ʻaʻole wale ia e koi i ka wai nui o nā mea e hoʻokō ai i nā koi o ka hana ʻana o nā mea hana, akā hoʻokō pū nō hoʻi i nā koi o ke apo stiffness grade o nā huahana (ʻoi aku ka nui o ka papa S2 ma mua o 8KN. /m2, no kekahi mea, ʻoi aku ka nui o ke anawaena, ʻoi aku ka liʻiliʻi o ka waiwai o ke apo. ʻAʻole hiki i ka huahana ke hōʻea i ka 8KN / m2. ʻO ka helu hoʻāʻo ʻo ke apo i ka mahana maʻamau (23 ± 2 ℃) ʻo 6.2kN / m2, kahi e koi ai i ka hoʻololi ʻana o ka mea a koi aku me ka ʻole e hōʻemi i ka hana o ka HDPE2480 kumu. ma lalo o ke ʻano o ka hōʻoia ʻana i ka loli o ke apo, ka hopena haʻahaʻa haʻahaʻa a me ka ikaika o ka hopena notch o ka huahana; E hoʻomaikaʻi i ka modulus kulou o nā mea e hōʻoia ai i ka pae o ka ʻoʻoleʻa huahana.
ʻO ke kaʻina hana no ka hoʻopiha piha ʻana i ka masterbatch o ka nui caliber high density polyethylene bellows hiki ke hoʻokō i nā koi o ka nui o ka caliber bellows ring flexibility, haʻahaʻa haʻahaʻa haʻahaʻa, notch hopena ikaika a me kekahi mau kulou make.
Hoʻohui ʻia me 30-50% D50 = 2-7 ​​μm ultrafine calcium carbonate a me 50-70% ultrafine talc pauka, ua hoʻomākaukau ʻia ka pauka composite.
ʻO ka hoʻopiha piha ʻana o nā mea haku i hoʻololi ʻia i hana ʻia me nā mea pauka composite hiki ke hiki i 50% i ka HDPE nui-diameter bellows.Ma lalo o ke kūlana o HDPE∶ mea hou hoʻololi haku mea = 50∶50, ke kaumaha o ka paipu me ka like kaliber piʻi wale 5 ~ 6%, a me kona kulou modulus a hiki i 1360Mpa.ʻO ke kūpaʻa a me ka hopena o ka mea me ka ikaika flexural o 24Mpa e like me ka mea i hoʻololi ʻia i ka wā i hoʻopiha ʻia me 30%: ʻo ka ikaika tensile ʻo ≥24Mpa, a me ka helu rupture o 10 mau mea hoʻohālike me ka hopena hopena ma 0 ℃ ʻoi aku ka liʻiliʻi ma mua o 1, e hoʻokō pono ana i nā koi o nā bellow HDPE nui-caliber.
Hoʻohana i ka 30 ~ 50% D50 = 2 ~ 7μm superfine calcium carbonate a me 50 ~ 70% superfine talc pauka e hui ai i loko o kahi pauka 100-hapa, e hoʻohui i 0.2 ~ 1 ʻāpana hui hui i loko o ka pauka composite a hoʻoulu ʻia no 5 ~ 10 mau minuke ma 120 ~ 140 ℃.A laila e hoʻohui i 3 ~ 6 ʻāpana o ka aila keʻokeʻo, 1 ~ 2 ʻāpana o ka waikawa stearic, 1 ~ 2 ʻāpana o ka ʻaila silicone hydroxyl a me 20 ~ 30 mau ʻāpana o ka polyethylene a i ʻole polypropylene e hoʻoulu like ma hope o ka mea, ma 150 ~ 190 ℃ mahana, ma o ka extruder māhoe māhoe like me kona extrusion hui ʻia a me ka granulating.
No ka hoʻohui ʻana i ka nui o ka masterbatch a hoʻemi i ka ʻōpala a me ka lepo i ke kaʻina hana, ʻoki ʻia ka masterbatch a hoʻopaʻa ʻia e ka ea e loaʻa ai ka nui like.
ʻO ka mea hoʻohui ʻia ʻo ia ka mea hoʻohui titanate a i ʻole ka mea hoʻohui aluminate a i ʻole ka mea hoʻohui silane.
