Nā waiwai a me nā hiʻohiʻona

ʻO RE he mea hana hoʻohui kea ikaika loa, Hoʻohana ʻia i nā mea hoʻopili i hana ʻia e ka hydroxyl polyurethane, ka lāʻau kūlohelohe a i ʻole synthetic,

Loaʻa iā ia ka pilina maikaʻi loa hoʻohana ʻia ka ikaika i ka ʻōpala a me ke kaʻa i ka resin, antioxidant, plasticizing agent, pressure-sensitive etc.

Hiki ke hoʻohana ʻia ma ke ʻano he crosslinker ma kahi o BAYER Desmodur RE

Hoʻohana

Pono e hoʻohana ʻia ʻelua mea hoʻopili i loko o ka manawa kūpono ma hope o ka hoʻokomo ʻana i RE.

ʻAʻole pili wale ka lōʻihi o ka manawa kūpono i ka ʻikepili polymer o ka adhesive, akā ʻo nā mea pili ʻē aʻe (e like me resin, antioxygen, plasticizer, solvent, etc.

Ke kokoke i ka manawa kūpono, maʻamau he mau hola a i ʻole hoʻokahi lā hana, ʻoi aku ka paʻakikī o ka hoʻopili ʻana, a piʻi koke ka viscosity.

ʻO ka hope, lilo ia i ka jelly hiki ʻole ke hoʻololi. 100 mea hoʻopili maikaʻi, Hydroxyl polyurethane (Polyurethane account no kahi o 20%), RE dose 4-7. Chloroprene rubber (Rubber account for around 20%), RE is 4-7.

Waihona

E ʻoluʻolu e mālama ʻia i loko o ka pahu i hoʻopaʻa ʻia ma lalo o 23 ℃, hiki ke mālama ʻia nā huahana no 12 mau mahina.

He mea maʻalahi loa ia i ka mosture; e hua mai ke kalapona kalapona a me ka urea hiki ole ke hooheheeia me ka wai.

Inā ʻike ʻia i ka ea a i ʻole ka māmā, e wikiwiki ia i nā loli kala, akā ʻaʻole e pili ka hana kūpono.

Pūʻolo

750 g / ʻōmole a i ʻole 50 kg / pahu a i ʻole 180 kg / pahu a i ʻole ma muli o nā koi o ka mea kūʻai aku.

Manawa Hoʻouna

1, Ka nui: 1-1000 kg, i loko o 3 mau lā hana ma hope o ka loaʻa ʻana o nā uku
2, Ka nui: Ma luna o 1000 kg, I loko o 2 mau pule ma hope o ka loaʻa ʻana o nā uku.
