Hoʻākāka ʻano

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

Noi

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

Nā hiʻohiʻona/pōmaikaʻi

Pale ʻo DB 75 i ka hana ʻana, ka mālamalama a me ka hōʻino ʻia e ke aniau
o nā huahana polyurethane e like me nā kapuaʻi kāmaʻa, nā panela mea kani a me nā puka, nā huila hoʻokele, nā encapsulations puka makani, nā hoʻomaha poʻo a me nā lima.
Hiki ke hoʻohui maʻalahi ʻia ʻo DB 75 i nā ʻōnaehana polyurethane ʻala a aliphatic paha no nā hoʻoheheʻe thermoplastic, nā foams integral semi-rigid, ka ʻili ʻana i loko o ka mold, nā noi dope. Hiki ke hoʻohana ʻia me nā mea kūlohelohe a me nā mea pigmented. He kūpono loa ʻo DB 75 no ka hoʻomākaukau ʻana i nā pastes kala paʻa māmā no nā ʻōnaehana i ʻōlelo ʻia ma luna.
Nā pono hou aʻe:
maʻalahi ke pamu, wai hiki ke ninini ʻia e ʻae ana i ka lawelawe ʻole ʻana i ka lepo, ka nui hana automated a me ka hoʻopōkole ʻana i ka manawa hui
ʻeke wai āpau; ʻaʻohe sedimentation o nā mea hoʻohui i loko o ka pae polyol ʻoiai i nā mahana haʻahaʻa
kū i ka exudation/crystallization ma nā ʻōnaehana PUR he nui

Nā ʻano huahana Wai moakaka, melemele iki

Nā kuhikuhi no ka hoʻohana ʻana

Aia nā pae hoʻohana o DB 75 ma waena o 0.2% a me 1.5%, ma muli o ke substrate a me nā koi hana o ka noi hope loa:
Nā huʻa hoʻohui ʻelua ʻāpana reactive 0.6% - 1.5%
Nā mea hoʻopili 0.5% – 1.0%
Nā mea sila 0.2% – 0.5%
Loaʻa ka ʻikepili hana nui o DB 75 no nā noi he nui.
