Amasegonda make gusa, gukura kwigunga birasabwa kwiyongera inshuro 60-100 hanyuma uhinduke umusumari mwiza. Tuvuga ibi bikoresho byingirakamaro.
Imizingo n'amasahani yubukungu, Xps plaque mugihe yashyizwemo ishyirwa mubishushanyo byihariye cyangwa koresha ibikoresho byihariye no gufunga. Ingingo zingingo zerekeye umuntu ku giti cye, kimwe n'ahantu hashyizweho, bakunze guhinduka ibiraro bikonje. Ubushyuhe no ku isi yabonetse mu buryo buhoraho bwa Polyurethane ifuro (PPU) yambuwe ayo makosa.
Igifuni cya Polyurethane cyihuse, kikoreshwa mugushinyagurira hamwe ninganda zishingiye ku nganda, zakozwe nkibisubizo byimiti ibiri: Isaminetiote na polyol bivanze mukibazo cyo hejuru. Imiterere ya PPU yakozwe na Hermetic nyinshi (kurwego rumwe cyangwa ubundi) butanga imwe mumirongo yoroheje yubushyuhe buke mu bikoresho byo kwikuramo bisanzwe bikoreshwa mubwubatsi.
Kwinjiza kuri PPU Stepko yihanganiye ingaruka zo mu kirere n'ubushyuhe. Kugirango imiterere yibikoresho itagongana uv, urusaku rushyushye rutandukanijwe na plaster, irangi.
Ariko, ibi bikoresho bifite izindi nyungu nyinshi. Muri Polinethane ifuro nta toxine zihindagurika. Biragira urugwiro ni urugwiro kandi hakanirwa kubuzima bwabantu. Ukurikije abakora, birashobora kuribwa nkigeragezwa. Kandi nubwo igifu kidacukura ibinyabuzima bitandukanije ibibyimba, ntagomba kugira ingaruka mbi kumubiri.
Polyurethane ifuro ifite uburyo bwo hejuru bwibikoresho byo kubaka, usibye polyethylene no hejuru ya fluoroplastique. Gukomera kw'ibice bitanga bikomeza mubuzima bwimiterere. Polyurethane ikubiyemo ibikoresho bidasubirwaho cyangwa bikabije (itsinda ryako rya Flammbility G1 cyangwa G2). Ni ukuvuga, mumuriro ufunguye, urashya, ariko ukimara kuba inkomoko yumuriro irazimira - irashira.
Hanze no imbere
Ppu lifer kuri shingiro, urufatiro rwinzu rurwanya ingaruka zakanishi nubushuhe, bukubitwa munsi ya 2% byimisa
Ibisabwa byo kwinjiza muri PPU biratandukanye cyane. Ni ukugira ngo igisenge, inkuta, urufatiro, aho duse, amagorofa, amagorofa n'akagari, itumanaho, itumanaho, ibidendezi. Amasosiyete yihariye akoreshwa no kwinjiza ibice bya PPU kuva abakora batandukanye, muri bo "Vlatermix", "Chimtrast", Bayer, Bayer, Farntman, Synthesia.
Inzira yo gusaba ntabwo yoroshye kuva aho ibona ikoranabuhanga, guhitamo ibice n'ibikoresho. Ubwiza bwibikoresho byambere byabakora ibishoboka bitandukanye biratandukanye. Ibigo bifite uburambe bwagutse, nkitegeko, tanga guhitamo amahitamo menshi kubikoresho bibisi ku giciro gitandukanye, hamwe nibintu bitandukanye. Byongeye kandi, bamenyereye ibiranga ibiranga mubishushanyo bitandukanye.
Igice cya Ppu ("Ecotermix") hamwe nubunini bwa mm 10 igabanya urusaku na 37 db. Polyurethane ifuro ntabwo yoroshye gusa, ariko nanone hejuru ninzego zuburyo bugoye. Ibikoresho byatewe muburyo bwamazi, kandi iyo bikonje bisaba imiterere.
Ibigize PPU bivanze muburyo runaka ukoresheje generator ya foam hamwe nigitutu kinini binyuze muri pistolet idasanzwe yatewe hejuru. Ibikoresho bikoreshwa nigice gikomeye, cyuzuze ibice bito. Nyuma yibyo, kumasegonda make ihimbano, kwiyongera mugihe cyibihe 100, no gusuka, gukora urwego rugana. Bitewe no kumenyekana hejuru, byizewe hejuru hejuru, nta yihuta. Ubushyuhe bwubushyuhe bwumubumbyi bwifuzwa buboneka kubice bimwe cyangwa byinshi. Igice cyarangiye kiraramba kandi gifunze. Ntabwo ifite icyuho.
Urufatiro rwo gusaba PPU rugomba gukama, rufite isuku, rwanga. Ku bitose kandi, byongeye, ubuso bwamavuta bwifuro ntibuzakomera. Kugabanya ubushyuhe bukabije, ibice byihariye bya PPU bigamije ibisanzwe bikoreshwa. Mugihe cyohereje PPU Gutakaza Umuvuduko mwinshi wibintu hafi 5-10%, kandi iyo ukorera mugihe cyo kwishyiriraho igitutu - 20-30%. Nkuko imyitozo yerekana, ingano yo kwigunga irangiye kuva mubikoresho bimwe mubyimwuga kandi hashobora gutandukana inshuro 2. Umukoresha w'impamyabumenyi yo hasi azahabwa Heron na buke ku buso butunganijwe.
Polyurethane yakiriwe CAISDON irinde amazi akonje muri pompe no muri sisitemu yo gutanga amazi, itanga ibikorwa byamazi yo gutanga amazi ashingiye ku iriba mugihe gikonje
Igiciro cyibikoresho
Igiciro cya 1 M² cyogushimwa gikozwe mubice bitatu byingenzi - Iki nigiciro cyibikoresho bikoreshwa nibikoresho byihariye kandi mubyukuri bikora. Ikiguzi (ubutunzi umurimo) ku bakunja rw'inyuma PPU gikomeye na igerekeranye Umubyimba kuva cm 2.5 kuri 10 bishobora gutandukana Burusiya 550 ngo 1130. Kuri 1 m², kwinjiza imbere ppu yoroshye ppu hand ubunini bwa cm 5 kugeza 15 buhagaze muburyo buke: kuva kuri 350 kugeza 750. Kuri 1 m².
Ibihe bidahwitse byo kuyobora akazi, nko gutera hejuru ya m 3 cyangwa gutunganya igisenge, ongera igiciro cyo kwishinyagurira 10-20%. Mu buryo busa, ibintu bitoroshye nabyo bigira ingaruka, muri byo harimo ubushyuhe bubi kandi bukaba bworoshye mu kirere cyijimye, buganisha ku bicuruzwa byinshi. Mugabanye ikiguzi cyo gutera ppu irashobora gushishoza ahantu heza (kurenza 1000 M²). Ahantu hato (kugeza kuri 200 M²), birashoboka gukoresha Polyurethane ifunze muri ballon (hafi kg 1), bisa na silinderi hamwe na foam. Koresha ibikoresho ukoresheje imbunda. Igipimo cyo gusaba PPU kuva silinderi kugeza umugambi wa 1 m² ni iminota 2 gusa.
Nyuma yo gutera ubushyuhe, icyumba gikorerwa muminota 15-30, nyuma yibyo PPU ntabwo igenera ibice bihindagurika kandi ntabwo binuka. Guhuza hejuru hanyuma ukureho ibice bibyimba, koresha igishishwa cyangwa igiciro gikaze
Ibyiza
- Ubushyuhe buke bwo kwitwara neza: Kuva kuri 0.019 kugeza 0.03 w / (m • k).
- Amajwi meza yo kwishyuza.
- Ibikoresho byoroheje, ntabwo biremereye uburyo bwo gutwara.
- Ubunini buto bwo kuzenguruka: kuva kuri cm 5 kugeza 15.
- Umuvuduko mwinshi.
- Imyitwarire yo kwishishoza kubera ugufi yifuro kubikoresho byose byubaka, ubukana bwurwego, hatabayeho kubura ingingo, habaho ibiraro.
- Gutwikira hejuru yubusa, harimo curvilinear.
- Ibikoresho bya biologique.
- Ubuzima Burebure: Kuva mumyaka 20 nibindi byinshi.
Ibidukikije
- Gukenera gukurura inzobere hamwe nibikoresho byihariye nubuhanga bwo gutera.
- Ingorane iyo ukorana nubukonje.
- Cranes kuva ku ngaruka za UV imirasire ya UV.
Pamp ikomeye cyangwa yoroshye?
Polyurethane ifuro igabanijwemo kandi yoroshye. Ubwoko bwa mbere burimo ibikoresho byakozwe na selile nyinshi zifunze. Iyi nyubako irinda inyura mu rwego rwo kwinginga mu kirere, ubuhehere, buka n'amazi. Ubucucike bwibintu: 20-60 kg / m³, gukorana ubushyuhe: 0.02-0.03 w / (m • k). Kubera imbaraga zihagije, irashobora kwihanganira guhura na mashini, byingenzi mugihe wubaka urufatiro rwinyubako. Byongeye kandi, kwinjiza PPU bigoye gukoreshwa hejuru yinzu, hamwe no kwinjiza hanze yimiryango nishingiro.
Imiterere ya PPU yoroshye yakozwe no guhuza selile zifunguye. Ubucucike bwibintu: 8-20 kg / m³, gukorana ubushyuhe: 0.035-0.06 w / (m • k). Ni elastike, ifite ibipimo byiza kubushyuhe n'amajwi meza, ariko byoroshye kugira ingaruka mbi. Yafunguye selile ppu yatsinze igikona runaka, kimwe nigiti cyangwa amatafari. Kubwibyo, ibikoresho bikoreshwa mumakuru yimbere. Kandi nukuvuga, igiciro cyacyo ntigirenze igiciro cya Harsh PPU.
Cylinder hamwe na Polyurethane Polyurethane Polynor irahagije kuri 1 M² hamwe nubwinshi bwa cm 5 (1 Cylinder - 468 Rables). Nyuma yo guhabwa impamyabumenyi, imbunda yogejwe hamwe nisuku Polynor Cleolnor (1 Cylinder - 155b.)
Andrei Zarestky, Umuyobozi mukuru witsinda rya ekotermix
Kubwamahirwe, kwinjiza Polyurethane akenshi byigisha, bizirikana muburyo bwakazi. Bagerageza ibikoresho bitandukanye kandi bagatanga ikiguzi gito cyakazi kubangamira ubuziranenge. Byinshi muribi bigade koresha igenamigambi rihendutse (20-50 umurongo). Mugihe ibisubizo bihamye bitangwa gusa ibikoresho byimisoro yo hejuru (hejuru ya bar 100). Kwizera akazi ko guterana bigomba kuba abahagarariye abayobozi bahagarariye abakora ibicuruzwa bya PPU. Bafite ibikoresho byikoranabuhanga mu misozi miremire, kandi ba shebuja banyuze mumahugurwa akwiye. Bahindukirira abanyamwuga, barimo abafatanyabikorwa b'ikigo cyacu, batanga serivisi zo kuburira, umukiriya ahabwa ingwate yemewe ku gihingwa, aribwo perigade yigenga idashobora gutanga.
