Paipu Wai Wela a me Anu PB
Hoʻolauna ʻia ka Paipu Wai Wela a me ke Anu PB
ʻO ka paipu Polybutene (PB) kahi polymer inert molecular kiʻekiʻe. ʻO ka resin PB kahi mea polymer i hana ʻia mai ka butene-1. Loaʻa iā ia kahi mānoanoa kūikawā o 0.937 g/cm3 kristal, he kino heterogeneous me ka maʻalahi. No nā huahana ʻenehana kiʻekiʻe o nā mea kemika organik. A he kūpaʻa wela kiʻekiʻe, kūpaʻa, kūpaʻa kemika a me ka plasticity. He ʻono ʻole, ʻaʻohe ʻawaʻawa, ʻaʻohe ʻala, he pae mahana mai -30°C a i +100°C, a he kūpaʻa anu, kūpaʻa wela, kūpaʻa kaomi, ʻaʻole popo, ʻaʻohe corrosive, ʻaʻohe scaling, a he ola lōʻihi (50-100 mau makahiki). A he mau ʻano o ke kūpaʻa ʻana i ka wā ʻelemakule. ʻO ia kekahi o nā mea kemika ʻoi loa ma ka honua. Hoʻohana nui ʻia ia ma nā ʻāina he nui o ka honua. A he inoa kaulana ʻo "gula i loko o ka plastic".
ʻO nā paipu wai anuanu a me ka wela kiʻekiʻe PB (polybutylene) he 24 mau huahana. Ua māhele ʻia i 4 mau kikoʻī mai dnl6 a i dn32. Wahi a ka moʻo paipu, ua māhele ʻia i ʻeono moʻo: S10, S8, S6.3, S5, S4 a me 3 .2.
Ka Hoʻokaʻawale ʻana o nā Paipu Wai Wela a me Anu PB
Hoʻomaʻemaʻe ʻia a hana hou ʻia nā mea hoʻoheheʻe organik ʻōpala i hana ʻia ma ka ʻoihana semiconductor ma lalo o nā kūlana hana like ma o kahi mea hoʻoponopono e hana i nā huahana e like me ka wai hoʻohemo B6-1, ka wai hoʻohemo C01, a me ka wai hoʻohemo P01. Hoʻohana nui ʻia kēia mau huahana i ka hana ʻana i nā panela hōʻike kristal wai, nā kaapuni hoʻohui semiconductor a me nā kaʻina hana ʻē aʻe.
Nā hiʻohiʻona o ka PB Hot and Cold Water Pipe
1. He māmā, maʻalahi a maʻalahi hoʻi ke kūkulu ʻana. ʻO ke kaumaha o ka paipu PB ma kahi o 1/5 o ke kaumaha o ke paipu kila galvanized. He maʻalahi a maʻalahi hoʻi ke lawe. ʻO ka radius kūlou liʻiliʻi loa he 6D (D: ke anawaena waho o ka paipu). Hoʻohana ia i ka pilina hoʻoheheʻe wela a i ʻole ka pilina mechanical, kahi kūpono no ke kūkulu ʻana.
2. He kūpaʻa maikaʻi kona, ʻaʻohe ʻawahia a ʻaʻohe mea ʻino. Ma muli o kona kaumaha molekala kiʻekiʻe, paʻa kona ʻano molekala. ʻAʻohe mea ʻawahia a ʻaʻohe mea ʻino a he ola lawelawe ʻaʻole i emi iho ma mua o 50 mau makahiki me ka ʻole o ka radiation ultraviolet.
Loaʻa iā 3.t ke kūpaʻa maikaʻi i ka hau a me ke kūpaʻa wela. ʻOiai ma -20°C, hiki iā ia ke mālama i ke kūpaʻa hopena haʻahaʻa maikaʻi. Ma hope o ka hoʻoheheʻe ʻana, hoʻi ka paipu i kona ʻano mua. Ma lalo o ke kūlana o 100℃, mālama maikaʻi ʻia nā ʻano hana āpau.
4. He mau paia paipu laumania kona a ʻaʻole e unahi. Ke hoʻohālikelike ʻia me nā paipu galvanized, hiki iā ia ke hoʻonui i ke kahe ʻana o ka wai ma 30%.
5. He maʻalahi ke hoʻoponopono. Ke kanu ʻia ka paipu PB, ʻaʻole ia e hoʻopaʻa ʻia i ka sima. Ke hōʻino ʻia, hiki ke hoʻoponopono koke ʻia ma ka hoʻololi ʻana i ka paipu. Eia nō naʻe, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ke ʻano casing (paipu i loko o ka paipu) no ke kanu ʻana i nā paipu plastik. ʻO ka mea mua, e uhi i ka paipu PB me ka paipu PVC hoʻokahi paia corrugated, a laila e kanu iā ia, i hiki ke hōʻoia ʻia ka mālama ʻana i ka wā e hiki mai ana.
