1. I-Foam esezingeni eliphakeme yekhwalithi ephezulu ayigezili phezu kobuso, futhi ilungiswe kahle kuyo. Ekugcineni inqimba ye-foam ye-foam ayiba buthaka futhi iphule, noma ngabe ivezwa amazinga okushisa aphansi.
2, 3, 4. Lapho wenza lo msebenzi, isilinda esinezinkulo (2) nezobuchwepheshe (3, 4) FOAM kufanele zigcinwe "zibheke phansi" ukuze i-gaspropellet ekhanyayo ixutshwe kangcono nezinye izinto zokugibela futhi ibasuse kusuka ethangini. Ngezikhathi ezithile, isilinda kufanele sinyakaziswe ukuze umnikazi anganqamuki kusuka ku-prepolymer. Kuyadingeka ukugcina ama-cylinders nge-foam kuphela endaweni ebheke phezulu emazingeni okushisa angu-5-25 C. Isisindo amathuba okuvuza konyaka kuzoba mancane.
Ukuphuma kwesilinda, i-prepolymer yandisa kakhulu inani (izikhathi ezingama-20-40) futhi liphenduka libe yigwebu. Ukunwebeka, kungena emikhunjini enzima kakhulu ukufinyelela, ukugcwalisa kalula yonke imifino. Lapho-ke isisindo seselula senziwa kancane kancane i-polymerized (qina), sidonsa umswakama ovela emoyeni noma nge-pre-onsisiwe. Ngemuva cishe ngosuku, iba yinto eqinile yamakhemikhali - i-polyurethane. Akuyona ingozi, ayibhujiswa isikhathi eside, imelana nomswakama. Le mali eqinile eqinile eqinile iqukethe amaseli ahlukahlukene avaliwe futhi iyisitayela esihle.
I-Foam ekhuphukayo inamathela ezintweni eziningi zokwakha: izinkuni, ukhonkolo, itshe, insimbi .d. Ngakho-ke, kusetshenziswa ngempumelelo lapho kufakwa iminyango namafasitela, ukufakwa komsindo kanye nokufakwa okushisayo, lapho ufaka izingxenye zokwakha, izimbobo, ama-slow, amalunga nemisipha emikhakheni ehlukahlukene (kufaka phakathi izindawo zokufaka ezindongeni zezakhiwo.
Phakathi kwabakhiqizi balo mkhiqizo - IHenzel (Brand Makroflex, eFinland), iBison Braven, bobabili (bobabili - I-Netherlands), I-Soudal Group (Tytan, Hauser, Bau Master, UDomos (Kokubili - I-Estonia), i-Okyanus Kimya (uphawu lwentengiso soma fix, turkey), "i-hermetic trej" (izinhlobo zokuthenga "izipikili ezikhulu", Chip, Puterch, Russia). Intengo elinganisiwe yesilinda nge-Foam ekhuphukayo incike kwivolumu yayo, isisindo, ukuthandwa komkhiqizo futhi ngama-ruble angama-100.

Izakhiwo ezihlukile ezinjalo
Impahla eyinhloko ye-Foam ekhuphukayo yikhono le-prepolymer ukwandisa ngemuva kokuphuma kwesilinda. Kuboniswa yisandiso, esisukela ku-40 kuye ku-60% (ekhaya) futhi ukusuka ku-180 kuya ku-300% (ipeni lochwepheshe). Izinga lokunwetshwa kanye nevolumu ye-foam ephumayo (isivuno sayo) lithonywa yizici eziningi: izinga lokushisa elikhona nesilinda, isivinini sohlelo lokusebenza, isibhamu noma i-adaptha), inamba ye-prepolymer ngaphakathi kwebhaluni kanye ne-mastery yomuntu owenza umsebenzi. Imvamisa, abakhiqizi bakhombisa isivuno se-Foam esiphezulu. Empeleni, leli nani lingatholakala uma abantu besebenza ezimweni ezijwayelekile futhi behambisana nazo zonke izidingo zemiyalo.
Ukwanda kwe-foam kuyisisekelo (ngokushesha ngemuva kokuphuma kusilinda) kanye nokwenzeka kwesibili okwenzeka kungakapheli isikhathi esithile kuze kube yilapho inqubo ye-polymerization iphelele ngokuphelele. Imikhiqizo eyenziwe ngempesheni eyenziwe ngesibili ingu-20-30%. Lokhu kubhekwe lapho kubhekwa lapho kucutshungulwa imithambo nemithumo, bekugcwalisa hhayi ngokuphelele, kepha ngu-2/3 kuphela, ukuze ivolumu lihlale likhululekile ekunwetshisweni kwesisindo se-Foaming.

Kunezidingo ezithile zamasu okuphepha lapho usebenzisa i-Foam ekhuphukayo yesibhamu. Akunakwenzeka ukuqondisa iphuzu lesibhamu kubantu noma ezilwaneni; Kulandela egumbini elinomoya omuhle, elinombuso ovikelayo phambi kwamehlo.
Amandla wokunamathela ngezindawo ezihlukile ze-surface zibonisa ukunamathela kwegwebu elikhuphuka. Kukalwa ngomzamo wokuphulwa kokutholwa kokutholwa kokutholwa (ngokwesibonelo, ukuguqula isampula). Ukumelana ne-Foam Shift kungu-0.4-0.48 MPA. Kubalulekile ukwazi ukuthi isisindo se-foam asinamatheli kwimikhiqizo enezindawo zokuhlala i-inert: polyethylene, polypropylene, i-teflon idre. Izinto zokwakha eziningi nemikhiqizo zixhumana kahle nayo.
Igwebu elikhuphukayo kufanele libe nokunwebeka, noma i-elastic, okungukuthi, linempahla edonswa kabusha ngaphansi kwesenzo semithwalo yemishini, nangemva kokususa ama-voltages, ibuyele kwifomu lasekuqaleni ngaphandle komonakalo. Akuyona imfihlo yokuthi izakhiwo eziningi zokwakha ezindlini ezintsha nezindala zihlala phansi ("Hamba"). I-insulator elastic izokumelana nale moto ngaphandle kwezinkinga, futhi zingabhubhisa kanzima.
I-Harding Foam ayiyona ingozi empilweni yabantu. Izinto eziyingozi zabelwe kulo kuphela ngesikhathi sokuvutha, futhi uma umthombo womlilo ususiwe, isisindo segwebu lizophuma. Ama-foam ahlukene angaba namakilasi ahlukene okumelana nomlilo: B1, B2, B3 (DIN 4102). Izinga lokushisa lokuzishisa kwalokhu okuqukethwe kungaphezulu kwama-400 C.
Amagwebu noma amagwebu asekhaya?
Qaphela ukuthi ekwakhiweni kwamakhemikhali, ama-foams asendlini kanye nezobuchwepheshe afanayo, yize owesibili aqukethe ama-reagents angcono. Ama-Cylinders anegwebu lezindlu afakwe ngeshubhu lepulasitiki eline-lever (adaptha). Kuyinto elula ukuyisebenzisa ngamanani amancane omsebenzi. Ngemuva kokusebenzisa konke okuqukethwe kwesilinda, ishubhu liyasuswa, ligezwe futhi ligcinwe kuze kube yilapho kusetshenziswa okulandelayo. Isilinda esine-foam ebekiwe (isibhamu) esikhuphukayo sivela esitsheni ngokuba khona komndeni kwe-apula elikhethekile le-apula. Isibhamu esikhuphukayo sokondla nokuthola i-Foam jet iqandisiwe. Isibhamu sifakwe umgqomo wensimbi omude lapho kufaneleka khona ukusebenza ngisho nasezindaweni ezinzima ukufinyelela kuzo, ngaphezu kwalokho, kukuvumela ukuthi uthathe umthamo ngokuqinile umphumela we-foam. Kuliqiniso, kufanelekile ukuthi idivaysi ibiza kakhulu kunebhaluni uqobo - ama-ruble angama-250-4000. Ama-Cylinders anegwebu eliqeqeshiwe, njengomthetho, anevolumu enkulu nesisindo, okusho ukuthi isivuno esiningi segwebu sinikezwa. Zisetshenziswa ngabakhi nasekulungiselelweni, nsuku zonke besebenzisa i-polyurethane sealant. Ngemuva kokuphothula iziqu, isibhamu sihleliwe futhi sahlanzwa ngokucophelela ezinsalweni zegwebu elinezindlela ezikhethekile.
I-coefficient yokuvuselelwa okushisayo kwe-foam mass yi-0.028-0.033W / (m k). Leli nani alicaciswanga kumasilinda, kepha noma yimuphi umsebenzisi onentshisekelo azoyithola encazelweni yezobuchwepheshe eyengeziwe yomkhiqizo ngamunye. Umbala we-Avocence we-Foam ungaba ngaphandle kokufunda imibhalo. Imvamisa, iningi lethu livame ukubona ama-bump aphuzi aphuzi noma ansundu, avimbela ama-slots azungeze i-perimeter yewindi noma eminyango. Lokhu kungumphumela wethonya lemisebe ye-UV akukho lutho oluvikelwe yi-insulator eqandisiwe. Inokumelana ne-Devanced kunoma yimaphi amathonya asemkhathini, ngaphandle kokukhanya kwelanga, ngenxa yawo kancane kancane emnyama futhi ewa, eminyakeni emi-2-3 iphenduka ibe yi-duch. Ukuthi lokhu akwenzeki, zonke izitembu ezivulekile kufanele zipendwe, zilungiswe noma zivale noma yiziphi izinto ezakhayo. Lapho-ke ungaqiniseka ukuthi i-Foam izosebenza iminyaka eyi-10-20 futhi nangaphezulu.

Ingxenye eyodwa noma ezimbili?
Ngaphezu kwepeni eliphakathi nendawo elilodwa, kunengxenye emibili. Ziqukethe izakhi ezimbili ezixutshwe ngengxenye ethile ngaphambi kokusebenzisa. Lokhu kudinga ukufakwa okukhethekile nesibhamu (uma izifunda zisezitsheni ezihlukile) noma izibhamu kuphela (uma izakhi zibekwa kwiphakheji elilodwa). Izakhiwo zepeni elilodwa nelinezinhlaka ezimbili ziyehluka. I-polymerize yesibili kungakhathalekile ukuthi umswakama womoya futhi unesilinganiso esiphakeme sokuvula. Isibonelo, i-foment-compon Foam Madrofl ex Fapipero (Helkel), i-Illbruck 2K (Tremco Illbruck), iSoudafoam 2K (Soudal) yaqina ngokushesha kangangokuba kungenzeka ukuthi inqunywe ngaphezulu kwemizuzu engu-4-10 ngemuva kokufaka isicelo. Imikhiqizo enjalo iphume ngokwengeziwe, kepha futhi ibiza kakhulu.Umbono we-Specialist
Uma umsebenzi wokufaka wenziwa ekushiseni okukhona ngaphansi kwe-5.C, kunconyelwa ukusebenzisa i-Foam ekhuphuka ebusika. Kodwa-ke, izinga lokushisa lesilinda kufanele libe ngu-20-22C. Ukupakishwa nge-foam ekhuphukayo, egcinwe ezakhiweni ezingapheliwe, kufanele zigcinwe emazingeni okushisa asekamelweni (18-25с) ngezinsuku eziyi-1-2. Ukusheshisa ukufudumala, ungabeka isilinda emanzini afudumele ngamazinga okushisa angaphakeme kune-35c futhi ngezikhathi ezithile anikina ngezikhathi ezithile. Akunakukwazi ukwenziwa ngaphansi kwesilinda ngokubeka imiphumela yegwebu elikhulayo lamazinga okushisa angaphezu kuka-50c. Lokhu kuzoholela ekwandeni okuqinile kokucindezela kukagesi ngaphakathi kwebhaluni futhi, mhlawumbe, ekuqhumeni kwalo. Uma ama-cylinders nge-foam ekhuphukayo ayeseLangeni noma awathuthele emotweni uSuku olushisayo lwehlobo futhi bafudumeza ngenhla kwama-30s, ukwakheka kumele kuphohliwe ngaphambi kokusebenzisa. Bamba amasilinda emazingeni okushisa asekamelweni phakathi nosuku noma okokucwilisa isikhashana emanzini abandayo bese unikina ngezikhathi ezithile.
I-Maya Bruzygin, ubuchwepheshe obukhulu benkampani "i-Hermetic-Trade"
Isizini ebusika - ihlobo
Izimo ezifanele zokusebenzisa i-Foam ezikhuphukayo zimi ngokulandelayo: izinga lokushisa nemvelo, namasilinda - 15-25 .I-Air Air Rament - 60-80%. Ngasikhathi sinye, umucu we-foam esezingeni eliphakeme ngesigaba esingu-3.53.5 cm lukhuni ngo-1. Imisebenzi yokwakha nokuqeda ibanjwa ngezimo kude neze. Isibonelo esilula: Ukuze i-polymerization ephumelelayo ye-Foam Mass idinga umswakama olwanele womoya. Uma inani layo lingaphansi kwama-30%, ochwepheshe batusa ukufafaza ingaphezulu kusuka ku-sprayer lapho i-foam izosetshenziswa khona bese ithomu uqobo. Vele, kuyadingeka ukukwenza kancane (njengoba besho, ngaphandle kokuthola isibambiso). Ngemuva kwakho konke, ukuthambisa ngokweqile ngokweqile kungaholela ekubhujisweni kwesakhiwo se-foam, lapho amaseli avaliwe azoqhuma khona, futhi inqwaba yokwehla ngevolumu.

Ukwehla kwezinga lokushisa okukhona, okungaphansi kwe-prepolymer kuyanda, futhi ngenxa yalokho kungaphansi nokukhishwa kwegwebu. Izinga lokushisa lehlisa inqubo yokulapha, ukwelula kusuka ku-1 kuye ku-10h. I-Foam ejwayelekile yehlobo isetshenziswa ekushiseni kwe-5-35c. Okokushisa okuphansi ngisho nangokwezingalo ezingezinhle (kuze kube -10 - 15c), amagwebu asebusika ahloselwe. Ukwakheka kufaka phakathi izingxenye ezikhethekile ezivumela ukuthi zinamathele ngokuqukethwe okuncane kwamanzi emoyeni. Inzuzo ye-foam yesizini yonke ukuthi banebanga elikhulayo lokushisa okusebenzayo. Kodwa-ke, ngokusho kokubuyekezwa, le mikhiqizo iyakhula hhayi kahle njengokuguqulwa kwehlobo.
I-Foam ekhuphukayo ihle futhi iwela ngaphansi kwesenzo sokukhanya kwelanga, ngakho-ke zonke izindawo ezigxiliwe kufanele zifihlwe ngempela: ziboshwe, zipendiwe.
Amanye ama-nuances
Abakhiqizi bancoma ukugcwalisa i-foam ekhuphukayo yobubanzi be-cavity ububanzi ukusuka ku-1 kuya ku-8-10 cm. Le mikhawulo iqinisile. Kunzima kakhulu ama-slots okuthi kunzima ukumane asebenzise inani elifanelekile lezinto ezibonakalayo, kanye nengozi yokuguqulwa kwe-design ngenxa yokwanda kwesibili kuyanda. Okungafakwanga, kunalokho, amandla e-Frozen Foam angenele ukubamba isakhiwo. Kuyasiza kakhulu ukugcwalisa izitini, it.p. (Ngendlela, kuzobiza okushibhile). Izikhala ezibanzi ezifanayo zinzima ukunqwabela kanyekanye ngale ndlela eyenziwa yisakhiwo esisodwa. Kodwa-ke, kwamukeleka impela ukugcwalisa izingqimba eziningana, njengoba impahla ihlungwa kahle naye.Ukunakwa: Umphumela weSpaghetti
Ungagcini ngezibhamu zokufaka igwebu. Imikhiqizo eshibhile yepulasitiki, njengomthetho, ayithinteki ngekhwalithi enhle yama-valves futhi imvamisa ayihlanganiswe kabi ngama-valve kumasilinda ngegwebu. Uma isibhamu esinjalo sivulwa indandatho yesicelo, lapho ucindezela i-trigger esikhundleni se-jet enamandla, igwebu lizophuma into efana ne-macaronin. Lokhu kubizwa ngokuthi yi-spaghetti umphumela. Iqiniso ngukuthi isibhamu esibi sivula i-valve hhayi ngokuphelele, kepha kancane. Ngakho-ke, igesi ye-oscillating ayihlanganisiwe ne-prepolymer, njengoba kufanele, kepha izimpukane, futhi isisindo asigxili ngokwanele. Ngenxa yalokhu, esikhundleni sevolumu ye-foam echazwe kwisilinda, uzothola okumbalwa, nekhwalithi embi kakhulu.
Ukuthenga igwebu, naka impilo yeshelufu: imvamisa kuyizinyanga eziyi-12-18. Kungcono ukusebenzisa i-foam ngaphambi kokuphela kwayo. Yize kukhona i-nuance ethokozisayo: Ngokuhamba kwesikhathi, i-viscosity ye-prepolymer iyakhula, futhi le nqubo isheshiswa ngosuku lokuphelelwa yisikhathi. Isisindo se-viscous sikhula sibi kakhulu kunoketshezi. Izinhlangothi, umphumela womkhiqizo ovela kubhaluni onjalo uzoba ngaphansi kokusuka kukhiqizwe nje, kepha ngakolunye - isakhiwo samaselula se-foam sizophuma sibe sincane, futhi ngenxa yalokho okungcono.
Ngaphambi kokuqala umsebenzi, abakhiqizi bayeluleka ngokuqinisa isilinda nge-Foam (izikhathi 10-20 noma phakathi kwemizuzwana engama-30). Lapho igcinwa, izakhi zinuka: igesi likhuphuka likhuphuka phezulu, futhi isisindo se-viscous sehlisiwe. Ukuthola ukwakheka okujwayelekile kokukhipha, kufanele kuxutshwe, okwenzekayo ngesikhathi sokuzamazama.
Lezi zindawo okufakwa kuyo i-foam ebekwe kuyo kufanele zihlanzeke futhi zingezithuli. Zingaba manzi, kepha kungabikho cala azimbozwa ngeqhwa noma nge-anem (uma umsebenzi wenziwa emazingeni okushisa amabi).
Usebenzisa i-foam ekhuphukayo, qiniseka ukugqoka izingilazi zokuphepha namagilavu, gwema ukuxhumana ne-Skin Sealant, sebenza kuphela egumbini elinomoya omuhle.
Khumbula ukuthi amagesi amagwebu asindayo kunomoya futhi ongezinto ezivuthayo, ngakho-ke ezindaweni zomsebenzi akunakwenzeka ukubhema noma ukusebenzisa imishini engaholela emlilweni ovulekile, izinhlansi, ngakho-ke izingozi zomlilo.
