ʻO ke ʻano

ʻO DB 75 kahi ʻōnaehana wela wai a me nā ʻōnaehana māmā i hoʻolālā ʻia no nā polyurethanes

Palapala noi

Hoʻohana ʻia ʻo DB 75 i nā polyurethanes e like me Reaction Injection Molding (RIM) polyurethane a me thermoplastic polyurethane (TPU). Hiki ke hoʻohana ʻia ka hui ʻana i ka sealant a me nā noi adhesive, i ka uhi polyurethane ma ka tarpaulin a me ka papahele a me ka ʻili synthetic.

Nā hiʻohiʻona / pono

Kāohi ʻo DB 75 i ka hana ʻana, ka māmā a me ka hoʻohaʻahaʻa ʻana i ka wā
ʻO nā huahana polyurethane e like me nā kapuaʻi kāmaʻa, nā mea kani a me nā pani puka, nā huila hoʻokele, nā encapsulations pukaaniani, ke poʻo a me ka hoʻomaha lima.
Hiki ke hoʻohui maʻalahi ʻia ka DB 75 i nā ʻōnaehana polyurethane aromatic a aliphatic paha no nā hoʻoheheʻe thermoplastic, semi-rigid integral foams, in-mold skinning, dope applications. Hiki ke hoʻohana ʻia me nā mea kūlohelohe a me ka pigmented. He kūpono loa ka DB 75 no ka hoʻomākaukau ʻana i nā paʻi kala paʻa māmā no nā ʻōnaehana i ʻōlelo ʻia ma luna.
Nā pōmaikaʻi hou aku:
maʻalahi e pāpaʻi, wai hiki ke hoʻoheheʻe ʻia e ʻae i ka mālama ʻana i ka lepo me ka ʻole o ka lepo, ka mea hoʻohana maʻalahi a me ka pōkole o ka manawa hui
pūʻolo wai a pau; ʻaʻohe sedimentation o nā mea hoʻohui i ka pae polyol ʻoiai ma nā haʻahaʻa haʻahaʻa
kū'ē i ka exudation/crystallization i nā ʻōnaehana PUR he nui

Nā ʻano huahana Māmā, wai melemele iki

Nā kuhikuhi no ka hoʻohana

ʻO nā pae hoʻohana o DB 75 ma waena o 0.2% a me 1.5%, ma muli o ka substrate a me nā koi hana o ka noi hope:
ʻO nā huʻihuʻi hoʻohui ʻelua ʻāpana ʻelua 0.6 % – 1.5 %
Nā mea hoʻopili 0.5 % - 1.0 %
Nā mea hoʻopaʻa paʻa 0.2 % - 0.5 %
Loaʻa ka ʻikepili hana nui o DB 75 no nā noi he nui.
