I. Nā hiʻohiʻona waiwai:
Hana ʻia ʻo PVC me ka vinyl chloride monomer (VCM) polymerization, ʻo ka mea PVC he mea ʻawaʻawa ʻole, anti-aging a me nā hiʻohiʻona kūpaʻa a me ka alkali, no laila kūpono loa ia no ka hoʻohana ʻana i ka pipeline kemika.A me ka PVC maka mea e hoʻohui i kekahi nui o nā mea hoʻohui paʻa (ʻaʻohe plasticizer) haku mele o ka hui ʻana, i kapa ʻia he polyvinyl chloride paʻakikī (i kapa ʻia ʻo UPVC).
ʻO CPVC kahi mea polymer i hoʻololi ʻia e ka chlorination o ka polyvinyl chloride (PVC) hou.Ma hope o ka chlorination, piʻi ka chlorine o ka resin PVC mai 56.7% a i 63-69%, e hoʻonui ai i ka paʻa kemika a pēlā e hoʻomaikaʻi ai i ka pale wela a me ke kūpaʻa corrosion o ka waikawa, ka alkali, ka paʻakai a me ka oxidant o ka mea.ʻOi aku ka kiʻekiʻe o kona wela deformation wela a me nā waiwai mechanical ma mua o ka UPVC.No laila, ʻo CPVC kekahi o nā mea ʻenehana maikaʻi loa no nā pipeline ʻoihana.
2. hoʻolauna ʻōnaehana pipeline:
ʻO ka ʻōnaehana pipeline UPVC a me CPVC he kūpaʻa ʻino, ka hopena o ka hopena, ʻaʻole maʻalahi i ka deformation, ʻoluʻolu o ka paia o loko, ʻaʻole maʻalahi i ka pālākiō, ka insulation thermal maikaʻi, non-conductive, kūpono i ka hoʻopaʻa ʻana, lōʻihi ke ola lawelawe a me nā ʻano ʻē aʻe.No laila, hoʻololi mālie ia i nā ʻōnaehana paipu metala ʻē aʻe i ka maikaʻi o ka hana kiʻekiʻe a me ke kumu kūʻai haʻahaʻa, a ʻo ka UPVC a me ka CPVC piping ʻōnaehana maʻalahi a me ka mālama wikiwiki ʻana, me ka ʻole o ka manawa lōʻihi a me nā poho nui, no laila ʻo UPVC a me CPVC paipu ʻōnaehana ke koho mua. no ka hoʻolālā paipu ʻoihana i kēia manawa.
ʻO 60 ℃ ka wela o ka lawelawe i ʻae ʻia o ka ʻōnaehana paipu UPVC, a ʻo ka mahana lawelawe lōʻihi he 45 ℃.He kūpono ia no ka lawe ʻana i kekahi media corrosive me ka mahana ma lalo o 45 ℃;Hiki ke hoʻohana ʻia no ka lawe ʻana i ka wai kaomi maʻamau, maʻamau i hoʻohana ʻia i ka wai a me nā paipu hoʻoheheʻe, nā pipelines irrigation mahiʻai, nā pipeline ʻenekinia kaiapuni, nā pipeline air conditioning a pēlā aku.
ʻO 110 ℃ ka wela o ka lawelawe i ʻae ʻia o ka ʻōnaehana paipu CPVC, a ʻo ka mahana lawelawe lōʻihi he 95 ℃.He kūpono ia no ka lawe ʻana i ka wai wela a me nā media corrosive i loko o ka pae kaomi ʻae ʻia o ka maʻamau.Hoʻohana maʻamau i ka petroleum, chemical, electronic, electric power, metallurgy, pepa, meaʻai a mea inu, lāʻau lapaʻau, electroplating a me nā ʻoihana ʻoihana ʻē aʻe.
