Paipu wai wela a me ke anu PB
ʻO ka hoʻomaka ʻana o ka paipu wai wela a me ke anu PB
ʻO ka paipu Polybutene (PB) he polymer inert kiʻekiʻe. ʻO ka resin PB he mea polymer i hoʻohui ʻia mai butene- 1. Loaʻa iā ia kahi kikoʻī kūikawā o 0.937 g / cm3 crystal, he kino heterogeneous me ka maʻalahi. No nā huahana ʻenehana kiʻekiʻe o nā mea kemika organik. A loaʻa ke kūpaʻa wela kiʻekiʻe, kūpaʻa, kūpaʻa kemika a me ka plasticity.
ʻAʻohe ʻono, ʻaʻohe mea ʻawaʻawa, ʻaʻala ʻole, loaʻa ke ʻano wela o -30 ° C a +100 ° C, a me ke anu, pale ʻole i ka wela, paʻa ʻole, ʻaʻohe ʻōpala, ʻaʻohe ʻino, ʻaʻole hoʻopalapala. , a he lōʻihi kona ola (50-100
makahiki). A loaʻa iā ia nā hiʻohiʻona o ke kūpaʻa ʻelemakule lōʻihi. ʻO ia kekahi o nā mea kemika ʻoki loa i ka honua. Hoʻohana nui ʻia ia ma nā ʻāina he nui o ka honua. A loaʻa iā ia ka inoa o "gula i loko
palaki”.
ʻO ka hoʻohālikelike ʻana o ka paipu wai wela a me ke anu
Hoʻomaʻemaʻe ʻia nā mea hoʻoheheʻe kūlohelohe i hana ʻia i loko o ka ʻoihana semiconductor ma lalo o nā kūlana kaʻina hana kūpono ma o kahi mea hoʻoponopono e hana ai i nā huahana e like me ka wehe ʻana i ka wai B6-1, ka wehe ʻana i ka wai C01, a me ka wehe ʻana i ka wai P01. Hoʻohana nui ʻia kēia mau huahana i ka hana ʻana i nā panela hōʻike aniani wai, semiconductor integrated circuit a me nā kaʻina hana ʻē aʻe.
ʻO nā hiʻohiʻona o ka paipu wai wela a me ke anu PB
1. He māmā ke kaumaha, maʻalahi a maʻalahi ke kūkulu. ʻO ke kaumaha o ka paipu PB ma kahi o 1/5 o ka paipu kila galvanized. He maʻalahi a maʻalahi ke lawe. ʻO ka radius piko liʻiliʻi he 6D (D: pipe outer diameter). Hoʻohana ia i ka pilina hoʻoheheʻe wela a i ʻole ka pilina mechanical, kahi kūpono no ke kūkulu ʻana.
2. Loaʻa iā ia ke kūpaʻa maikaʻi, ʻaʻohe mea ʻawaʻawa a me ka pōʻino. Ma muli o kona kaumaha mole kiʻekiʻe, paʻa kona ʻano molekala. ʻAʻohe mea ʻawaʻawa a maikaʻi ʻole a he ola lawelawe ʻaʻole ia ma lalo o 50 mau makahiki me ka ʻole o ka radiation ultraviolet.
3.t maikaʻi ka hau a me ka wela. ʻOiai ma -20 ° C, hiki iā ia ke mālama i ka hopena maikaʻi haʻahaʻa haʻahaʻa. Ma hope o ka hoʻoheheʻe ʻana, hoʻi ka paipu i kona ʻano kumu. Ma lalo o ke kūlana o 100 ℃, mālama mau ʻia nā ʻano āpau o ka hana.
4. He mau paia paipu paheʻe ia a ʻaʻole paʻakikī. Ke hoʻohālikelike ʻia me nā paipu galvanized, hiki ke hoʻonui i ka kahe wai ma 30%.
5. He maʻalahi ka hoʻoponopono. Ke kanu ʻia ka paipu PB, ʻaʻole ia i hoʻopaʻa ʻia i ka pahu. Ke pōʻino, hiki ke hoʻoponopono koke ʻia ma ke pani ʻana i ka paipu. Eia nō naʻe, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka casing (pipe in pipe) no ke kanu ʻana i nā paipu plastik. ʻO ka mea mua, e uhi i ka paipu PB me ka PVC pale hoʻokahi paipu corrugated, a laila kanu iā ia, i mea e mālama ai i ka wā e hiki mai ana.
hiki ke hōʻoiaʻiʻo.
