Indlela yokusebenza komlawuli we-foam

Isilawuli se-Foam siyisengezo samakhemikhali esisetshenziswa kakhulu, esidlala indima ebalulekile ezisetshenziswayo eziningi zezimboni, ikakhulukazi ekwenziweni kwepulasitiki ye-foam nezinye izinto eziqukethe amabhamuza. Lokhu okulandelayo izindlela eziyinhloko zokusebenza kwesilawuli se-Foam:
Nciphisa ukucindezeleka kobuso boketshezi
Ama-foam regulators ngokuvamile angama-surfactant anganciphisa kakhulu ukucindezelwa kobuso boketshezi. Lesi sici senza kube lula ukuthi uketshezi lwakhe amabhamuza azinzile. Lapho ama-foam regulators engezwa kuketshezi, akha ifilimu elincane ebusweni boketshezi elivimbela ama-molecule omoya ukuthi angangeni ngaphakathi koketshezi. Lapho uketshezi luvuselelwa noma lunyakaziswa ngamandla angaphandle, umoya uzobhajwa kuketshezi, wakhe i-foam 1.
Khiqiza igesi
Ezinye izinhlobo zezilawuli ze-foam, ikakhulukazi izinto ezikhipha amagwebu zamakhemikhali, zikhiqiza amagesi ngokusebenzisa ukusabela kwamakhemikhali. La magesi akha amagwebu oketshezini, okuholela ekukhiqizeni igwebu. Ukusetshenziswa kwe-agent ye-foam yamakhemikhali kudinga ukulawulwa okuqondile, ngoba igesi eningi ingabangela ukungahlaliseki noma ukuphuka kwegwebu4.
Ukugqwala ngokomzimba
Ngaphezu kwalokho, ezinye izilawuli ze-foam zingenisa igesi oketshezini ngezindlela ezibonakalayo, njengokuxuba noma ukugunda ngesivinini esikhulu, ukuze kwakheke i-foam. Le ndlela ngokuvamile idinga imishini namasu akhethekile ukuqinisekisa ukuthi igesi ingasatshalaliswa ngokulinganayo oketshezini.
Thuthukisa isakhiwo samaseli kanye nobuningi be-foam
Ekukhiqizweni kwezinto ze-polymer foam, abalawuli be-foam bangathuthukisa kakhulu isakhiwo seseli kanye nobuningi be-foam. Ngokulungisa uhlobo kanye nenani lomlawuli we-foam, izinga lokunwebeka kanye nesakhiwo seseli se-foam ye-polymer kungalawulwa ngokunembile, ukuze kufezwe ukusebenza okuthile okudingekayo. Isibonelo, i-meta polyanhydride ingalungisa isakhiwo kanye nosayizi weseli we-foam enesisindo esiphansi, kuyilapho i-phenolic resin ingalawula ukwanda kwe-polymer kanye nesakhiwo se-foam2.
Thuthukisa amandla okuncibilika nokugeleza kwamanzi
Enye yezinhloso zokwengeza ama-polymer anesisindo sama-molecule aphezulu kakhulu emikhiqizweni ye-foam ye-PVC ukuthuthukisa amandla okuncibilika kwezinto ze-foam ze-PVC, ukuvimbela ukuhlangana kwama-bubbles, nokuthola imikhiqizo ene-foam efanayo. Ngesikhathi esifanayo, lokhu kuqinisekisa nokuthi i-melt inokuguquguquka okuhle ukuthola imikhiqizo ebukeka kahle.
isiphetho
Abalawuli be-foam basebenza ngezindlela ezahlukahlukene, okuhlanganisa ukunciphisa ukucindezeleka koketshezi ebusweni, ukukhiqiza igesi, ukushukuma ngokomzimba, kanye nokuthuthukisa isakhiwo samaseli kanye nobuningi be-foam. Lezi zindlela zisebenza ndawonye ukwenza abalawuli be-foam badlale indima ebalulekile ekukhiqizweni kwezinkambu ezahlukene, njengokudla, izimonyo, amakhemikhali ansuku zonke kanye nezinto ze-polymer foam. Kodwa-ke, lapho kusetshenziswa abalawuli be-foam, kufanele kuqashelwe futhi umthelela wabo emvelweni, ukuphepha, kanye nezindleko ukuze kufezwe intuthuko esimeme.
