Hoʻolauna Huahana
Hot-Dipped Galvanized PC Strand haʻahaʻa hoʻomaha prestressed kila strand ua hana ʻia i ʻehiku wela wela i hoʻopaʻa ʻia me nā uʻi kila a puni me ka pale ʻana i ka corrosion maikaʻi, hiki ke hoʻolōʻihi i ke ola o nā mea i loko o ka mokuʻāina o nā wahi corrosive e like me nā wahi kahakai, i ʻike ʻia ʻo ia. he ʻano kūpono o ka pale ʻana i ka corrosion i kēia manawa a ma ka honua.
Pili kēia maʻamau i ke kaula alahaka, nā ʻāpana hoʻopaʻa paʻa, hoʻokiʻekiʻe a hoʻopaʻa ʻana i nā ʻāpana ʻāʻī o nā hale a me nā hale hana prestressed ʻē aʻe, ʻaʻole i hoʻohana pololei ʻia i nā kūkulu grouting concrete, anawaena: 12.7mm, 15.mm, 15.7mm, 17.8mm, ikaika. papa: 1770MPa, 1860MPa, 1960MPa. (ma hope aku i kapa ʻia ʻo "paʻi kila").
ʻO ke ʻano o ka 1x7, 1x19 wela-hoʻopaʻa galvanized prestressed steel strand series huahana, ka ikaika tensile hiki ke hōʻea i 1860MPa a me nā kikoʻī like me ke kaula kila PC maʻemaʻe a puni e pili ana i nā pae hana acc.to GB/T 33363, ASTM A416, EN10138, BS a me ka NFA35-035 etc.
Nā hiʻohiʻona huahana
Hiki ke hana ʻia ka huahana e like me nā noi o ka zinc coating mai nā mea kūʻai aku, hiki i ka zinc coating ke piʻi i ka 250 gsm a i luna paha, ʻo ka like ʻana o ka ʻāpana zinc coating he 3-4 mau manawa me ka wehe ʻole ʻana i ke keleawe, a ʻaʻole i haki ka adhesion a ʻaʻole i ʻili. ma lalo o ke kūlana ma ka wili ʻana i 8 pōʻai ma hope o ka uhi ʻia ʻana o ka zinc.
Ma muli o nā mea hana holomua o ka hui, hiki iā mākou ke hoʻolālā i ke kaʻina hana galvanized e hoʻokō i nā koi kūikawā o nā mea hoʻohana i ka maikaʻi o ka papa zinc, ka maikaʻi o ka honua, etc.
Ke hoʻohālikelike ʻia me ke kaula kila PC me ka uhi ʻole ʻia a me ke kaula kila PC galvanized, ʻike ʻia ka mea mua i ka ʻulaʻula ma hope o ka hoʻāʻo ʻana i ka paʻakai no 24 mau hola.
Nā hoʻololi laʻana o ke kaula kila PC me ka uhi ʻole ʻia a me ke kaula kila PC galvanized ma hope o 21 mau lā o ka hoʻāʻo ʻana i ka paʻakai paʻakai ʻole penei,
Nā noi huahana
1) Hiki ke hoʻohana ʻia nā huahana i ka ʻenekinia kūkulu hale a me ke kākoʻo ʻana i ka ʻenekinia mine mine ma lalo o nā kūlana kūlohelohe.
2) I nā makahiki i hala iho nei, ua hoʻohana ʻia ma ke kahua o ka mana makani. "1x7-medium 21.6mm, Large-Sized Hot-Dipped Galvanized PC Steel Strand", i hoʻohana ʻia ma ka honua "160m, low-wind-speed prestressed frame wind turbine tower", me ka hiki ke lawe kiʻekiʻe, kahi conductive e hoʻomaikaʻi. ka pale makani o ka halekiai. Me ke kūpaʻa corrosion maikaʻi, hiki ke hoʻonui i ke ola lawelawe o ka hale kiaʻi.
ʻO ka hale kiaʻi kiʻekiʻe hoʻokolohua 160m haʻahaʻa makani haʻahaʻa ma Shandong
