Polyurethane pahuka i: kino ki te hauora. Ko te āhuatanga o te polyurethane pahuka i

He rite mākete hanga Modern ki te whakahere ona kiritaki te rauemi ki te whakamahi wā roa-a ingoa pūmau, me te rārangi roa o te waerau e haere mai i runga i te mākete kore pera i mua, me te tonu whiwhi āhukahuka o mua. Ko reira ki tenei rōpū me ngā polyurethane pahuka i.

He aha te mea te reira - he pahuka i polyurethane?

huanga tenei tohunga rauemi hanga hou ki te rōpū o kirihou hau-ki tonu. Polyurethane pahuka (PUF) Kei o te wāhanga hau e mangere o neke atu i te 85%. He whānui, me te momo hōkai o tenei rauemi. tautohetohe Heoi uaua ki runga ranei i te kino polyurethane ki te hauora hopoi mai, e kore e iti hoki nga tau maha. Ko te tino kōrerohia i tenei wāhi ko te pātai o te whanonga rauemi i roto i ngingiha me paheke o wāhanga paitini i raro i whakawera.

Ko te kōrero o te rauemi

humarie taea te huaina Rā o pahuka i whanau i roto i te 1937, ka ki he rōpū iti o pūtaiao i te taiwhanga Levenkuzene rauemi synthesized ki ngā āhuatanga rerekē. I runga anō i te mea ko te ōwehenga o te ranu wae rauemi hou, me te pehea ka mau tauhohenga nohopuku wahi, nga āhuatanga o te pahuka i polyurethane ki ripeneta rerekē. I runga i te ringa kotahi i ngāwari, me te manahau, engari pakarukaru nui ki pikaunga ka motu te rauemi. I te tahi atu te ringa - kaha, pakeke, kiato, ko te brittleness i piko. Kua whakatuwheratia e te rauemi ake he opuaraa tino whanui, engari tino pakanga te Pakanga Tuarua o te Ao ratou whakatinanatanga. Heoi, mai i te 60raa o te rau tau whakamutunga ka anga te hanga o te pahuka i ki te whakawhanake tere.

hanganga polyurethane Wae

Ko te wāhanga taketake e hanga ake te pahuka i me tika mo te hanganga me te tāpiritanga o te mekameka polymer he polyol (wāhanga A) me te polyisocyanate (wāhanga B). I te tahi taime e taea kaihanga polyol kāinga tāpiri i tētahi atu wāhanga - whakakōkī. Ko te wāhanga taketake o te pahuka i polyurethane he kakara motuhake, me te wai he ōrite feunga matotoru ki atarangi mai i te marama kōwhai ki te parauri pouri.

Polyol ki te rokiroki wā roa-e whangai ana ki te exfoliate, na e tūtohu ana i mua i te whakamahi i ki te uru. tauhohe Polyisocyanate ki te wai - i roto i tīmata whakapā whātioatanga. Hoki te rokiroki auroa i roto i tuwhera te kiriata rangi i hanga i runga i te mata rauemi. E ai ki tona pahuka i hanganga wae e taea kia o rua nga momo - mō te riringi a maka ana.

āhuatanga biogenic

Polyols me polyisocyanate whakamahia mō te polyurethane hanga he hua hinu. Heoi kua mohiotia taua mea e te wāhanga polyurethane me taea te hua i ngā hinu huawhenua. Ko te kōwhiringa pai mo tenei whakaaro - te hinu Katoro. kia hoki kia whiwhi te wāhanga polyol i te hinu putirā, soya, oilseed rape. Heoi, he tiketike nui te utu o enei rauemi mata, me te kore he ohaoha whai takenga te hanga. E hua rauemi pahuka i Biogenic i roto i ngā rahinga iti ka whakamahia ki te whakaoti rawa kuiti mahi motuhake.

ngā āhuatanga PPU

Polyurethane pahuka i, hangaia e ngā kaiwhakanao kāinga me te ke, kua he maha o e rua ngā āhuatanga pai me te kino.

Ko te iti rauemi waiariki kawe ia (0.019 - 0.03 W / m), te tata katoa kohu uruhanga, resistance wai polyurethane pahuka i wera pai, me te godroizolyatorom hanga. Ka taea e te taua te mea e pā ana ki te kaupare mātao tangi. hanga taea whakarea adhesion High ki te tono pahuka i ki tata tetahi mata.

Heoi, te āhuatanga te mau huru pai e kore anake polyurethane pahuka i. kia meinga tūkino i roto i te tahunga o te polyurethane pahuka i ki hauora tangata (ki te kaitahu te rauemi pūtake mura hāngai). I tua atu, E faatae mai polyurethane matū paitini - formaldehydes. Polyurethane, e huru wāhanga ki te rangi, me te wai, ātete ki te mana o te rā. Mai riro te reira pouri me te taka atu i runga i te wā.

Scope o te PPU

Tenei waerau whare hou whakamahia whānuitia i roto i mara ngā o te mahi a te tangata. Ko te rohe whānui o tona tono i roto i te hanga: mātao, mātao oro, me te wuru whare tivira, me te ahumahi o tetahi whakaaro (noho, mau fare whenua, toa, warehouses, hangars, me ētahi atu). Nā ki te kawe ia waiariki iti o te polyurethane pahuka i whakamahia mō te mātao e kore anake tuanui engari ano taiepa, e rua i roto me ngā whare i waho. He mahuinga ia mo te hanganga o ngā kaupapa hanganga taiwhanga awhi Sandwich o polyurethane pahuka i.

Pahuka i ki te kiato o te 30-86 kg / m³ (pahuka mārō) e whakamahia rite haruru me te rauemi tuuraa i ngāwhā. He rauemi ki te kiato o te 70 kg / m³ he hanganga mātotoru e kore e haere te wai, me te pai e whakamahia ana mō te wuru.

I roto i te hanga o te Refrigeration whakamahia rite PUF hladoizolyatora. Te ahumahi hu kaimahi he rauemi mo te hanga o ngā āhuatanga hū me tautoko kikorangi.

Heoi, i reira he wāhi wahi ai ko rawa pāhekeheke whai take o te rauemi pērā i polyurethane pahuka i. Ka taea e mōrearea hauora meinga te rauemi poupou me taima mo te taonga he papura, mattresses, urunga, me ētahi atu (Polyurethane kiato pahuka o 5-40 g / m³ - ngohengohe poraka raima). Ahakoa kaiwhakanao PPU me haapapû e he taiao, me te biologically kūpapa te rauemi, e taea hoki e meinga tona whakamahi kia rite ki te filler mō taonga tākaro whakaaro ngā mātua e pā ana ki te hauora o rātou tamariki.

Moe i roto i nga ringa o te pahuka i ...

Ka arotahi tatou i runga i ngā kaupapa pēnei moenga rite mattresses o pahuka i. Kino, me te kino nui, kia tono mā te ngongoa au paitini matatini pūhui matū ahua (e pā ana ki te 30 ngā momo), te kino tino o ratou he phenol me 2-ethylhexanoic waikawa. Ano, mattresses hou ki polyurethane pahuka i filler emit 5-6 wā matū atu mōrearea atu i te tawhito. Ko te kukū o kohu o enei matū e rite ki te secretions i te kuaha Whakakirihōu hou.

Fakapapau o mattresses haumaru ki filler polyurethane pahuka i pāhekeheke mo te take ohie e te kāpia whakamahia i roto i te taahiraa o to ratou hanga, kaiwhakakökï, whakarewa, wae matū hohe (phenol!).

He te riri o te phenol nui?

whakaaro phenol te he taonga paitini mo te take e hoatu ana e ia atu au paitini paitini, me tenei tukanga kahore ino mate o te tāoke ranei e taea muri mō tau. Ka taea e tēnei huānga matū meinga disorders o nga pūnaha nui o te tinana tangata: te romahā, io me Cardiovascular. Ka taea e te putanga e he ānini, mate o mahara, incoordination. kia hoki kia hono fakahohaasi te mahi o nga whatukuhu, me te ate. whakapā tamau ki phenol me ona kohu taea meinga te ahua o taua mate nanakia rite huangō, mate pūkahukahu hopuhopu, mate pāwera.

E ai ki te pūtaiao whai wāhi i roto i te rangahau i roto i tenei rohe, i te whakamahi o te polyurethane pahuka i mo te hanga o te taonga o ngā tamariki, mattresses, takawairore kiko. pai kia whakakapia PPU ki rauemi haumaru. Ki te he āwangawanga e pā ana ki te hauora o ratou tamariki mau metua, me waiho ratou rawa tahuri ki te whiriwhiri hoki ratou taonga tākaro me mattresses, te wahi rite taea te whakamahi i te filler i polyurethane pahuka i. Ko te nuinga o nga whenua ritenga rāhuitia te whakamahi o phenol mo te hanga o ngā hua rā.

He aha te kino?

E whakamahia tino whānui Products hanga o polyurethane i maha ngā wāhi o te ora te tangata. Polyurethane pahuka i me te poari pahuka i runga i te pūtake o te polyurethane pēhia ngā te pūkahukahu, kiri, kanohi. Peleti mō te mātao i hanga o polyurethane pahuka i, ki te rangi poliizotsoanatov pūhui paitini e taea o meinga mate pāwera huangō ranei. A, no te wera papa PUF whakawera pākahiko piki polyisocyanate rā tīpakonga ranei.

I roto i te take o ngiha pahuka i ahi me tuku hoki hau paitini, i te mea he puna atu o te ati, me te riri ki te ora. Heoi, ko reira ia tapao e kua whakamahia piki i roto i nga tau tata momo kore-pūkākā o te polyurethane pahuka i whiwhi e te whakataki ki to ratou hanganga tāpiritanga motuhake. kino polyurethane pērā ki te hauora, ko te whakaritea e kore e kino.

Na kei hea ko te pono?

pahuka i polyurethane - he aha te mea te reira? Kino ia ranei whai hua? He maha nga wahi i te whakamahi o te polyurethane pahuka i roto i ao rerekē o te ora te tangata e kore e hoatu i te whakahoki tino ki tenei pātai. Hoki te ahumahi hanga he reira tino pai, me te nui. He whai wāhitanga ki te hanga i te ranunga me te tono pahuka i ki ārai i te mata tika i runga i te pae hanga, me te whakaiti i nga utu hāngai ki te hanga i te pahuka i-mata nukurau kotahi, kahore āputa i roto i te huihui, me te ngāwhā piriti. Mātao o pipelines, ko whakauaua taea te mātao o iti-pāmahana paipa me te ahumahi matū i te kau ki te tōtika taua, e whakarato ana te pahuka i polyurethane.

Heoi, ko te whakamahi o tenei rauemi i roto i te hanga o taonga mo te iwi (me ngā tamariki i roto i ngā) maha tohunga i roto i tenei mara te mea e kore e tino tika. Paheke o matū paitini e taea whai i te pā tōraro i runga i te hauora tangata. i mua ara 2003, te hanga kāinga o wāhanga mo te hanga o te hangarau polyurethane pahuka i whakarato hoki te whakamahi o pūhui Etera tino ahua. I teie mahana, e fakapapau'i kaihanga i whakarerea i te hangarau. I roto i te 3 ra i muri i te tono o te rauemi wewete te i te nui iti o te hau e toe i muri i te wāhanga tauhohe, me he taiao pahuka i polyurethane hoa muri.

I roto i te whānui, i roto i ia take, i mua i te whakamahi i te hua o te polyurethane pahuka i, he mea e tika ana ki te whakatata whaitake te ki te aro mātai o te "pai me ngā raruraru" katoa o tenei rauemi i roto i tetahi ruri o te ora.
