Polyurethane HW - HW oe

Nā makahiki i hōʻike i ka hooulu ana o ka 'ike loea hou kēia, aole ia e ana i ka lua. Ulu nui hou ka paleʻana, 'ike loea iaono? Ienoai, hoʻonui nā manawa kūpono e uhau ana a me nā kānaka kūʻai mai Pono. Ke kumu nui ke keʻena o ke kālā? Acaeoey ua lilo iʻimi hoʻopunipuni mea - polyurethane. Ua Ua hoʻomano hoʻohana ', akā, ka hapanui pinepine ia hiki ke ike i ka hope o maoli laholio a me ka laholio. Naʻe, ka mea kū hoʻokahi waiwai o polyurethane ae ia e puku ea, a hiki metala.

Ano, eia nae, e kamaʻilio pū mākou no kēia huahana like me ka polyurethane HW. Ia mea i ka pono kekahi 'ano, he haʻahaʻa kāki, a me ka mea, pale aku me mechanical deformation, hiki ke ku imua o ke akea ka mahana huahelu, a mai ka pono lōʻihi hana ola.

Polyurethane HW ua i wehewehe aku ma kekahi degere kiʻekiʻe no e kū'ē'ē mai a hiki i ka luku keiki o nāʻakika a me alkalis, kela mea kāhinu, a me ka kakolina. Oia HW ka paleʻana hiki ke maheleia i mau pūʻulu: hookahi-ke keʻena a me nā-ke keʻena.

E like me ka inoa hoʻohuʻu, ka papa likeʻole ma waena o kēia mau pūʻulu i loko o ka nui o ka eiiiiiaiou. One-ke keʻena HW mea he'ōlewa laholio-me HW, a nana me ka maʻamau HW. i kūʻai koke makaukau e hoʻohana i na hui, a 'o ia hoʻi i ole hou ana no kona makaukau, a ho'ēmi i kā nui ka lōʻihi like' ole o ke kapili hana.

I ka Ia manawa, he mau o eiiiiiaiou e hoʻohui pū i ka polyurethane ka penaʻana - hoola iho la hope, a resinous 'ole - e ke aupuni' o kekahi ipu. Ka mea, pono e pili ana i ka mea i ho'ākāka 'huliāmahi. Eia naʻe, 'ike loea keia he nui kona maikaʻi hiʻona:

1. I ka ka penaʻana o ke kaʻina hana o ka poe paakiki, a me polymerization o ka haku mele 'ana. He ana holo me ka ona mau, a nolaila, e like me ka naohʻo ia ka mea hiki ole i ka hoʻolohe, e map kumumea like me ka hau, ka ua, ka noe.

2. Easy e paka i ka makemake ka leo o ka HW mea. Me ka i ka manawa i? Aneii wale i ke koi 'ia ka nui o ka inika hiki me ka nui loa ho'ēmi i kona hokii, a, nolaila, e hoola i ke kuai ana o ka pono hana. Eia naʻe, polyurethane HW poorly waiho i loko o ka dilution o ka wā lōʻihi o ka manawa. A hiki ma lalo o kekahi mau kumu.

3. E ho ohana i hopena o ka ikaika a me ka mau nō ka penaʻana. Ma keia e pili ana, elua-ke keʻena ka penaʻana mai i ka nui ia Morohiha maluna o ke dute hookahi ke keʻena.

Nolaila, ke polyurethane ka penaʻana e hoʻolako i ka Wear hoʻopale laholio ka penaʻana i ka nui kūpono hoʻopale i ÿole mechanical poino a me ka Nine Inch i huiʻia, a me ka mea, pale aku UV. Oia ka ka penaʻana ua hoʻomano palahalaha ae ma hoʻohana versatility: ia mea hiki, a mawaho, a na unuhi.
