ʻO Yuru Railway bridge polyurethane uhi wai

Description:

ʻO ka uhi wai wai polyurethane no nā alahaka kaʻaahi (no ke kaʻa kaʻa holo kiʻekiʻe) he ʻelua ʻāpana kemika hoʻoheheʻe wai. ʻO ka ʻāpana A kahi prepolymer hoʻopau isocyanate i loaʻa ma ka polycondensation o ka polyether a me ka isocyanate. Hoʻokumu ʻia ka Component B me ka mea hoʻoikaika a me ka plasticizer. ʻO ka wai kala i haku ʻia me nā mea hana, nā mānoanoa a me nā coagulants. I ka hoʻohana ʻana, hoʻohui like i nā ʻāpana A a me B, e hoʻopili iā lākou ma ka ʻaoʻao kumu wai, a me ka loulou keʻa a paʻa i nā wela kiʻekiʻe e hana i kahi kiʻi ʻoniʻoni elastic like me ka ikaika kiʻekiʻe a me ka elongation kiʻekiʻe.

hiʻona:

◇ Ka ikaika kiʻekiʻe, a hiki i ka 6.0MPa a ʻoi aku paha; maikaʻi elongation hana a maikaʻi haʻahaʻa wela hana.

◇ Hiki ke hoʻopili ʻia ka huahana me ka mānoanoa, a ʻo ke kiʻi ʻoniʻoni ʻoniʻoni ʻeleʻele a ʻeleʻele ʻole e hana i kahi papa wai elastic mau.

◇ ʻO ke kūkulu anuanu, hiki ke hana ʻia ke kūkulu ʻana ma hope o ka hui pū ʻana o nā ʻāpana A a me B i ka like, a maʻalahi ka hana.

◇ ʻO ka hoʻokumu ʻana i ke kiʻiʻoniʻoni kemika, ka pale ʻana i ka corrosion, ka pale ʻana i ka maʻi, ka haʻahaʻa haʻahaʻa haʻahaʻa, a me ka ikaika ʻole o ka wai.

noi:

ʻO nā papahana pale wai a me ka moisture e like me nā ala kaʻa holo kiʻekiʻe, nā ala ala, nā alaloa, nā papahana ma lalo o ka honua, nā papahana municipal, nā loko, nā dams, etc.;

Hoʻohana ʻia e hoʻopili i ka membrane wai a hoʻohana pololei ʻia e like me ka papa wai;

Hiki ke hoʻohana ʻia no ka mālama anti-corrosion o nā mea metala, pipelines, waʻa lāʻau, etc.

hoakaka:

'Apono kūpono:

1. Ka lōʻihi o ke ola lawelawe: hiki ke hoʻomau i nā makahiki he 50 ma hope o ʻekolu mau kapa pena.

2. Ke kū'ē kū'ē i ke aniau: Hiki ke hoʻomau i ka hana paʻa no ka manawa lōʻihi ma lalo o nāʻano aniau, aʻaʻole maʻalahi ka makahiki, haki a hāʻule paha.

3. Ke kū'ē kū'ē kemika maikaʻi: Loaʻa i ka puʻupuʻu PU ke kūpaʻa maikaʻi a hiki ke pale aku i ka hoʻoheheʻe ʻana o nā mea kemika e like me nā waikawa, alkalis, a me nā paʻakai, a pale i nā hale a me nā alahaka mai ka ʻino.

4. Hana maikaʻi i ka hoʻopaʻa ʻana: Hiki ke hoʻopaʻa paʻa ka uhi ʻana o ke alahaka ʻo polyurethane wai me ka mea kumu e hana ai i kahi papa wai ikaika, e pale pono ai i ke komo ʻana o ka makū.

5. Kiʻekiʻe elasticity a me ka maʻalahi: Railway bridge polyurethane waterproof coating he kiʻekiʻe ka elasticity a me ka maʻalahi, kiʻekiʻe tensile ikaika, nui elongation, ikaika kū'ē i ka base deformation, a hiki ke hoʻololi i ka deformation a me ka vibration o ke alanui a me ke alahaka hale, a 'aʻole maʻalahi. i Māhā a haki paha.

6. Hana maʻalahi: He maʻalahi ke kūkulu ʻana i ka uhi wai polyurethane alahaka ala a hiki ke hana ʻia e ka pulupulu ʻana, ka ʻōpala, ka ʻōwili ʻana, a me nā mea ʻē aʻe.

01 Nā mea nui o ke kūkulu ʻana:

◇ Pono ka papa kumu e paʻa, palahalaha, ʻaʻohe ʻōpala, a maloʻo loa.

◇ Pono e hui pū ʻia nā mea hoʻohui e like me ka hapa o nā ʻāpana ʻelua A a me B e like me ke ʻano o ke kūkulu ʻana, a hoʻoulu like ʻia me kahi koʻokoʻo uila. Pono e hana hou i nā ʻāpana node e like me ka mea e pono ai.

◇ Hoʻohana ʻia ke kūkulu ʻana i ka ʻōpala a i ʻole ka pulupulu ʻana, a pono ke ʻano like ka mānoanoa. ʻO ka mānoanoa maʻamau he 1.5mm-2.5mm, a pono e hoʻopau ʻia ma 3-4 mau ala. Pono e hana ʻia ka uhi ʻana ma hope o ka hoʻōla ʻana o ka uhi mua, a ʻo ke kuhikuhi o ka pulupulu ʻana a i ʻole ka pipi ʻana e kū pono i ka uhi mua.

◇ Ma hope o ka ʻae ʻia ʻana o ke kiʻi ʻoniʻoni, e kūkulu ʻia ka pale kaʻawale e like me nā koi hoʻolālā.

02 Pono nā mea e nānā:

◇ Hoʻohana ʻia i ka ua, ka hau, ka makani a me ke one, a me ke anuanu haʻahaʻa.

◇ Inā loaʻa ka ua ma ka māhele B, ʻaʻole ia e pili i ka maikaʻi o ka huahana. I ka hoʻohana ʻana, e hoʻoulu like a hui pū me ka mea A i ka like.

◇ Ua pāpā loa ʻia ke ahi ahi ma ke kahua kūkulu.

◇ Ma hope o ka ʻae ʻia ʻana o ke kiʻi ʻoniʻoni, pono ke kūkulu ʻia ka pale pale i ka manawa.

Papaa a me ka halihali:

E mālama i nā mea i loko o kahi lumi maloʻo a me ka makani. I ka wā o ka lawe ʻana, e makaʻala ʻaʻole e ʻike ʻia i ka lā a i ʻole ka ua, e pale aku i ka hui ʻana, a e hoʻolohe i ka pale ʻana i ke ahi. Hoʻokahi makahiki ka manawa mālama huahana. Hiki ke hoʻohana wale ʻia ma hope o ka hala ʻana o ka nānā hou ʻana ma hope o ka manawa mālama.

Kuhikuhi helu:No kēlā me kēia millimeter mānoanoa kiʻiʻoniʻoni, uhi ʻia ke kaumaha ma kahi o 2.2kg/㎡-2.6kg/㎡.
