ʻO ke kumu hoʻokomo keleawe PPR kala keʻokeʻo
PPR paipu
Ke hoʻohālikelike ʻia me nā paipu metala, ʻoi aku ka maikaʻi o nā paipu PPR o ka hoʻonohonoho maʻalahi, ʻoi aku ka maikaʻi o ka insulation thermal, a me ke kū ʻana i ka corrosion. ʻO ia ka mea ʻoi aku ka maikaʻi a me ka pili o ka wai wai a ʻo ia hoʻi ka huahana hoʻolako wai nui ma ka mākeke. Loaʻa nā paipu PPR i nā waihoʻoluʻu aʻe, keʻokeʻo, hina, ʻōmaʻomaʻo a me nā kala curry, no ke aha ke kumu o kēia ʻokoʻa ma muli o nā masterbatches ʻokoʻa i hoʻohui ʻia.
Ma kahi o nā hiʻohiʻona o nā paipu plastik maʻamau e like me ke kaumaha māmā, ka pale ʻana i ka corrosion, non-scaling, a me ke ola lawelawe lōʻihi, loaʻa i nā paipu PP-R nā hiʻohiʻona nui:
1 ʻAʻole ʻona a maʻemaʻe.
ʻO nā molekala waiwai o PP-R he mau mea kalapona a me ka hydrogen wale nō, ʻaʻohe mea ʻino a ʻona. He maʻemaʻe a hilinaʻi. ʻAʻole hoʻohana wale ia no nā paipu wai anuanu a wela, akā no nā ʻōnaehana wai inu maʻemaʻe.
2 Mālama i ka wela a mālama i ka ikehu.
ʻO ka conductivity thermal o ka paipu PP-R he 0.21w / mk, ʻo ia wale nō 1/200 o ka paipu kila.
3 ʻOi aku ka maikaʻi o ka pale ʻana i ka wela.
ʻO ka wahi palupalu o Vicat o ka paipu PP-R he 131.5 ℃. Hiki ke piʻi ka mahana hana kiʻekiʻe loa i 95 ℃, hiki ke hoʻokō i nā koi o ka ʻōnaehana wai wela i ka lako wai hale a me ke code wai.
4Loaʻa ke ola lawelawe.
Ma lalo o nā kūlana o ka mahana hana o 70 ℃ a me ke kaomi hana (PN) o 1.0MPa, hiki i ke ola lawelawe o ka paipu PP-R ke piʻi aku ma mua o 50 mau makahiki (inā pono ka mea paipu he S3.2 a me S2.5 series a i ʻole. hou aku); ma lalo o ka mahana maʻamau (20 ℃) Hiki ke ola o ka lawelawe ma mua o 100 mau makahiki.
5 Hoʻopili maʻalahi a pili pono.
He maikaʻi ka hana kuʻi ʻana o PP-R. Hiki ke hoʻopili ʻia nā paipu a me nā mea pono e ka hoʻoheheʻe wela a me ka electrofusion. He mea maʻalahi ka hoʻokomoʻana a ua hilinaʻi nā hono. ʻOi aku ka ikaika o ka hui ma mua o ka ikaika o ka paipu ponoʻī.
6 Hiki ke hana hou ia na mea.
Hoʻomaʻemaʻe ʻia ka ʻōpala PP-R, haki, a hana hou ʻia no ka hana ʻana i nā paipu a me nā pono. ʻAʻole ʻoi aku ka nui o nā mea hana hou ma mua o 10% o ka nui a ʻaʻole pili i ka maikaʻi o ka huahana.
