Polyurethane foam "Titan 65": ezibekiweko lobuchwepheshe

Polyurethane foam "Boiler 65" kuyinto eyodwa ingxenye polyurethane ingxube okuyinto senzelwe obandayo zokwakha futhi uphawu. Liveza adhesion okusezingeni eliphezulu nohlobo impahla:

• isitini;
• usimende;
• aphathekako;
• ugodo;
• izinsimbi;
• ingilazi;
• Styrofoam;
• PVC kanzima futhi kanzima.

Phakathi kwezici zayo ezihlaba yilezi: okusezingeni eliphezulu ukushisa-nangokuvikela ikhono umsindo-iyavuleka, ukumelana ukuguga, futhi ukubukeka ukuqhubeka isikhunta zesikhunta. Isicelo of the ukwakheka Kwenziwa isibhamu eqinisekisa ngesivinini nokushintsha kokudla nokufakwa futhi ukunemba okuphezulu umsebenzi.

umnotho

Njengoba umkhuba ubonisa, EVA Foam kuyinto ukonga kakhulu. Ngokusetshenziswa izingxenye ezintsha sizukulwane scalability okusezingeni eliphezulu kufinyelelwa eside Foam ukusebenza. Besuka komunye isilinda kabani ivolumu 750 ml, ungathola impahla 40% ngaphezulu. Uma sikhuluma izinombolo ethize, bese-ke imayelana 60 amalitha Foam ngesikhathi yesivini khulula namamitha 100 komugqa Slots. Kulo mBhalo, i-izimbotshana bengase bazikhandlele endaweni 5 cm ^2. Uma unesithakazelo ubude Slots, ningaqiniseka ukuthi 170 amamitha komugqa. Kulesi slot cross-Sectional kungenzeka 3 cm ^2.

izici lobuchwepheshe

Polyurethane foam "Titan 65" Ukucaciswa okumele kuyo uma uya uzosebenzisa amaphuzu ayo lapho imisebenzi siyingxenye ye le-butane ne diphenylmethane diisocyanate, kuyilapho umbala impahla ungukukhanya ophuzi. Ukuze usebenze le nto singaba ibanga lokushisa +5 ukuze +30 ° C, kanti ukushisa okungenani kungenzeka 0 ° C. Ungakwazi ukubala on isikhathi sokwelapha lekumele azuzwe ngangokunokwenzeka kumaminithi 12. Nakuba inani eliphansi of solidification - imizuzu 8, futhi phakathi naleso sikhathi isifinyelele Uthuli-DRM. Lezi zinqubo evumelekile uma izinga lokushisa ambient cishe elilingana 20 ° C, umswakama - 60%.

Foam inhlangano "Titan", Ukucaciswa, Standard okuzokwenza kube nentshisekelo hhayi kuphela ochwepheshe, kodwa futhi ukuze abathengi yangasese, libhekene nesikhathi pretreatment, okuyinto engavimba imizuzu 45, nomswakama ongafinyelela 93%. Qedela ukuqina kungalindeleka ubusuku bonke, ukuzinza ezishisayo kufinyelelwa emva kokuphothulwa isinyathelo sokuhlanganiswa, okuyilona elidingekayo ukuze kulondolozwe izinga lokushisa ezisukela -60 kuya +100 ° C.

Ungase futhi ube nentshisekelo kwabantu impahla, okuyinto 25 kg / m ^3, noma 0,025 g / cm ^3. ukuzinza ntathu, noma kunalokho, ukuncipha lingaphansi kuka-3%, izinga lokushisa lingase ulingana +40 ° C, futhi nomswakama ongafinyelela 95%, lokhu isigaba kuthathe amahora angu-24. Indaba ukudla kwezimila amanzi e isamba 1.5%, ukumuncwa esiphezulu ifinyelela Foam amahora angu-24. amandla compressive futhi ukunwebeka ngesikhathi esinikeziwe ukwakhiwa Foam kuyinto 0,07 futhi 0,22 MPA, ngokulandelana.

Ngaphambi abathengi ukuthenga avame sinake conductivity ezishisayo endabeni echazwe ngayo 0,036 W / Mcal. I kuphela ingasetshenziswa acetone, kodwa uyokwenza njengoba nje ngaphambi isinyathelo ukuhlanganisa. Ukuze abale lemali edingekayo impahla kubalulekile ukuba banake izici ukusebenza, kuba 65 amalitha noma 750 ml. Uma ufisa ukusebenzisa Foam izakhiwo ukuthi ibhekane imiphumela ilangabi kubalulekile ukujwayelana izici combustibility: B3 (Din 4102) kanye B2 (Din 4102).

izakhiwo Key

Foam inhlangano "Titan" GOST okuyinto okubonakale ukwakhiwa libukeka 22695-77, kufanele kusetshenziswe kuphela ngemva abajwayelene ngokugcwele izakhiwo eziyisisekelo. Ngakho, njengoba base lisetshenziswe ukukhiqizwa polyurethane zobukhulu bawo nezinto ngokwayo has a iphunga othize ngesikhathi isinyathelo sokwelapha. Nakuba emva kokuphothulwa le nqubo, indaba akusho Zikhiphela iphunga.

Lapho ofeza lokushisa kuma kungenzeka ilingana cishe 20 ° C, ukugudluka value set akuyona kakhulu. Isicelo kumele kwenziwe ezingeni lokushisa hhayi ngaphansana -10 ° C. Ungakwazi ukubala on yokuthi Foam uzobuyisa ukushisa ukumelana nezinkinga eziningi ezahlukene kunalokho ebanzi okushisa ukuthi zisukela kweziyizigidi ezimbili -55 kuya +90 ° C. Ngokwe-standard Din 52451, owawuthi ukukhiqizwa Kwenziwa, ushintsho emqulwini Foam kungaba cishe 20%. Kodwa kuyaqina e ukungezwani ilingana u-10%. Ububanzi esiphezulu igebe singavalwa 30 mm.

Izincomo zokusetshenziswa

inhlangano "Titan" igwebu, GOST, TU, okuyinto ihlonipha e womshini yayo futhi umsebenzi, kumele kusetshenziswe ngumkhiqizi. Ngaphambi kokuqala kwamanzi umsebenzi ukugeza ngobuningi wetted ngamanzi amagwebu isilinda kumelwe ngokwemvelo imenze ekamelweni lokushisa. Ngaphambi ukusetshenziswa, kufanele ayonyakaziswa cishe 20 izikhathi ukuthi iyadingeka ukuze kuhlangana.

I cap okuvikela ekhishiwe, kanye ibhaluni unamathele isibhamu. Iyasebenza, kumelwe lisabhekiswe phansi. Lapho usebenzisa i-Foam "Titan", ungakwazi ulungise ivolumu Foam extruded, it is kulawulwa ingcindezi isicelo kwi isibambo umlomo wombhobho noma isibhamu.

Slots kufanele uchichime nakuba kungaze kube yinxenye ukujula, njengoba impahla kuzokhulisa ivolumu emva kokuqedwa. Lapho ukusebenza Slots, ububanzi okuyinto mkhulu kunezinhliziyo 5 cm ke wazigcwalisa Kwenziwa kancane kancane futhi impahla sisetshenziswa izingqimba.

iseluleko kuchwepheshe

Polyurethane foam "Titan" ngemva kokusebenzisa kufanele zihlanzwe isibhamu ngokushesha, idinga ukusebenzisa wezindlu ngoba izibhamu. Ngemva solidifying Foam yayo kungenziwa usike, kodwa ebusweni ukuba camera kumele bavikelwe UV imisebe ngu ukumboza sealant, usimende noma upende.

isiphetho

Polyurethane foam "Titan" ngemva solidification angasuswa athutha kuphela kodwa ngaphambi solidification isinyathelo njengoba kuphela kungenziwa acetone, noma ekhethekile yokuhlanza ejenti kamakhi oyisebenzise.
