Igwebu (elibuye laziwe ngokuthi i-polyurethane foam sealant) liyi-polymer material enwebekayo futhi iqine ngokusabela kwamakhemikhali. Ihlinzeka ngempahla engasindi, i-thermal insulating, ivikela umsindo, kanye nezakhiwo ezingangeni manzi. Ngenxa yokusebenziseka kalula nokuvumelana nezimo, isiphenduke insiza ebaluleke kakhulu kubunjiniyela besimanje nempilo yansuku zonke. Okulandelayo ukusetshenziswa okuvamile kwegwebu kanye nezimo zabo zokusebenza ezithile:
I. Ukwakha Nokuhlobisa
1. Ukugcwalisa Izikhala kanye Nezikhala
Igwebu livame ukusetshenziselwa ukugcwalisa izikhala ezindongeni, ezicabheni nasezinhlakeni zamafasitela, kanye naseduze kwamapayipi. Ngemva kokunwetshwa, ibambelela ngokuqinile ezindaweni ezingavamile, ivimbela ngokuphumelelayo ukungena komoya nomswakama. Isibonelo, lapho ufaka iminyango namafasitela, i-foam ingagcwalisa igebe phakathi kohlaka nodonga, ithuthukise uphawu.
2. I-Sound and Thermal Insulation
Isakhiwo seseli elivaliwe{0}}legwebu livimba ukudluliswa komsindo futhi livame ukusetshenziswa kuma-interlayers odongeni noma ekugcwalisweni kosilingi ukuze kuncishiswe ukuphazamiseka komsindo. Ngaphezu kwalokho, i-thermal conductivity yayo ephansi (cishe i-0.03 W/m·K) inciphisa ukulahlekelwa ukushisa futhi ithuthukisa ukusebenza kahle kwamandla okwakhiwa.
II. Isondlo Sasekhaya Nemihla Ngemihla
1. Ukuvikela Ifenisha kanye Nokuvikela Ukushaqeka
Lapho kuhlanganiswa ifenisha, i-foam glue ingasetshenziswa ukugcwalisa izimbobo zesikulufa noma amalunga phakathi kwezingxenye ukuze kuthuthukiswe ukuzinza nokunciphisa ukunyakaza. Isibonelo, ukugcwalisa amakhabethe ngeglue eyigwebu endaweni oxhumene kuyo nodonga kungavimbela ukuxega ngemva{1}}kokusetshenziswa isikhathi eside.
2. Ukuvimbela Ukuvuza Kwepayipi kanye Nokufakwa Kwamanzi
Izimbobo lapho amapayipi amanzi noma izintambo zikagesi zidlula khona ezindongeni zingavalwa ngeglue eyigwebu, elingangenwa amanzi futhi lingasheshi ilangabi-elingavimbeli ilangabi (lihlangabezana nezindinganiso zokulinganisa umlilo ezingu-UL94).
III. Imboni kanye Nezicelo Ezikhethekile
1. Ukukhiqiza Nokulungisa Izimoto
I-Foam glue isetshenziselwa ukugcwalisa izimbobo ezicabheni zemoto, ophahleni, nakwezinye izindawo, ukunciphisa isisindo nokuthuthukisa ukuvala umsindo. Amanye{1}}amaglue amagwebu aphezulu angaphinde asetshenziselwe ukulungisa ubhampa.
2. Ukupakishwa kanye Nokuvikelwa Kwezokuthutha
Lapho uthutha izinto ezintekenteke, i-foam glue ingasetshenziswa ukugcwalisa izikhala emabhokisini ukuze kuvinjwe ukudlidliza nokushaqeka. Uma seselaphekile, ayisindi futhi ayinyusi izindleko zokuyithumela.
Izinyathelo zokuzivikela
-Nyakazisa ithini okungenani iminithi elilodwa ngaphambi kokulisebenzisa ukuze uqinisekise ukuxutshwa okulinganayo.
- Izinga lokushisa elinconywayo lohlelo lokusebenza liphakathi kuka-5℃no-35℃. Amazinga okushisa aphansi angase ehlise izinga lokunwetshwa.
- Ngemva kokwelapha, ingcina yegwebu idinga ukusikwa ngommese ukuze kuvinjelwe ukuguga kwezindawo ezivelile ezingase zithinte ukubukeka.
Ukuhlaziywa okungenhla kukhombisa ukuthi ukusetshenziswa kwe-adhesive ye-foam kudlulela ngalé kwe-caulking elula. Ukusebenziseka kwayo ngezindlela eziningi kuyenza ibe yisixazululo esisebenzayo kuzo zonke izimboni eziningi. Ukukhetha uhlobo olufanele lokunamathelisa igwebu (njengokukhula-okuphezulu noma ukumelana nomlilo-ukumelana nomlilo) nokuyisebenzisa ngendlela efanele kungakhulisa izinzuzo zayo zokusebenza.
