Amagwebu ebusika avumela ukubekwa uphawu kwamabhulokhi ewindi kanye neminyango kanye nezimbobo ezahlukahlukene zokuxhumana emazingeni okushisa aphansi. Sikhuluma ngobuhlakani bokusebenza kwabo.

I-Polyurethane ekhuphuka igwebu yizinto ezifakwayo ezibandakanya i-polymer isisindo kanye nephethelo legesi elivalekile kwisilinda esinguHelmetic. Injongo yayo eyinhloko ukugcwalisa, ukuvalwa okuvalwe uphawu, i-thermo- kanye nokufakwa okuzwakalayo. Faka isicelo segwebu lapho ufaka umnyango namabhulokhi wewindows, ukugcwalisa okungenamsebenzi kanye nomthungo emiklamo ehlukahlukene, kufaka phakathi lapho kubeka ukuxhumana kwezobuchwepheshe.

Ukusetshenziswa kwebanga le-foam elijwayelekile (ehlobo) kusuka ku-5 kuye ku-30 ° C. Ku-20 ° C kwigebe lama-30 mm ububanzi, isisindo liqandisiwe ngemizuzu engama-20-60, futhi inqubo ye-polymerization iphela ngosuku. Ukwehlisa izinga lokushisa okukhona, kukhudlwana ukubonwa kwezinto ezibonakalayo futhi kuhamba kancane kunokuphendula kwamakhemikhali. Ngasikhathi sinye, ngesikhathi sokwelapha, igwebu lidonsa kakhulu umswakama ovela emoyeni, futhi ngokuqala kwamakhaza, okuqukethwe kwalo emoyeni kuyancipha. Ngalesi sikhathi, kuyadingeka ukusebenzisa ama-foams asebusika. Ukwakheka kwabo kuguqulwa yizithasiselo ezikhethekile, ngenxa yokuvulwa okulungile kwesisindo esinqunyelwe kwenzeka kumazinga okushisa ancishisiwe (kuze kube -18 ° C) kanye nomswakama womoya. I-Foam ehlobo ezimweni ezinzima, ngemuva kwesikhashana ngemuva kokugcwalisa igebe, ingahle ibhidlika (i-Flush), futhi amandla efriwa angenayo angeke anganele, ngokuvezwa okuncane kwemishini kungenziwa. Izinto zokulungiswa kobusika zisindisa ukwakheka ngemuva kokuphulukisa, azilahli amapharamitha amandla kanye nezici ezidingekayo zokufakelwa okushisayo.
Ingaphezulu lesisekelo akufanele limbozwe ngeqhwa, iqhwa noma isayensi. Ukuthola isakhiwo esifanelekile se-foam, kusetshenziswa izingqimba eziningana ngobukhulu obungabi ngaphezu kuka-3-4 cm. Abakhiqizi abanconyelwanga ukunqamula isilinda kusuka kusibhamu ngaphambi kokuthi kuqediwe. Photo: Shutterstock / Fotodom.ru
Uyacelwa ukuthi uqaphele ukuthi ukwanda kwe-Foam kuhlukaniswe kwaba yinto yokuqala, ngokushesha endaweni yokuphuma kwesilinda, kanye nesekondari, elihlala kuze kube sekuphothulwe inqubo ye-polymerization. Kubalulekile ukubheka lapho ucubungula imithambo nemisipha. Imvamisa, ukunwetshwa kwesibili kungama-20-30%, ngakho-ke umthungo awugcwaliswa ngokuphelele, kepha ngezingxenye ezimbili kwezintathu.
Isilinda esifudumele se-Foam yasebusika

Uyacelwa uqaphele: Ku-Cylinder nge Foam, umenzi ukhombisa hhayi kuphela uhla lwamazinga okushisa okusebenza kwe-foam (kusuka ku-+30 ° C ebusika), kodwa futhi nokushisa okudingekayo kwebhaluni uqobo. Le yipharamitha ebaluleke kakhulu. Iqiniso ngukuthi emgqonyeni obandayo noma oshesha kakhulu ufudumeza isilinda esiphakeme se-foam. Umkhiqizo uhlala ezindongeni zethangi futhi uphuma kancane futhi ngokunganqikazi. Iphuzu elifanele lesilinda sokuphuma okuphezulu kwe-foam cishe ngo-23 ° C. Ngakho-ke, ngaphambi kokusebenzisa emakhazeni, kugcinwa emazingeni okushisa asekamelweni cishe ngosuku, futhi ngaphambi kokuqala umsebenzi, kunyakaziswa kakhulu (izikhathi eziyi-15- 20) ukuze okuqukethwe kuxutshwe. Yize lesi simo senza kube nzima kwinqubo, ngoba ibhaluni lisheshe liphola emakhazeni.
Ngokubona okukhulu kwe-foam ekhuphukayo okufanele kunamathiselwe, kungcono ukushisa (hhayi ngaphezulu kuka-30 ° C), ngoba ukukhuphuka kokushisa kwesisekelo kuthuthukisa ukunamathela. Lokhu kungenziwa nge-compressor efudumele yomoya.
Inqubo Yokubopha Ukuvalwa kwe-Window
Izindawo ezizoxhumana ne-Foam zihlanzwa ngothuli nezinye izinto ezinciphisa ukunamathela. Photo: Helkel
Isilinda nge-Foam sigcinwa emazingeni okushisa asekamelweni (20 ° C) okungenani amahora ayi-12. Ngaphambi kokusebenzisa, kuyanyakaziswa, khona-ke i-cap evikela iyasuswa bese isusa isibhamu. Photo: Helkel
Ngesikhathi sokusebenzisa i-foam, ibhaluni liphethe phansi. Indawo yokusebenza igcwele kusuka phansi-up, ukukhiqizwa kwesisindo kuphela esikhaleni se-slit, ngoba igwebu liyanda ngesikhathi se-polymerization. Photo: Helkel
Isisindo sobuningi besisindo silawula amandla okushicilela ku-pistol tr. Ngemuva kokuqinisa igwebu, okweqile kusikwa, futhi ungqimba olufakayo luvikelwe emisebeni ye-UV ngopende, udaka. Photo: Helkel
