Amandla okuguqula igwebu lethusi: isishintshi segeyimu kusayensi yezinto

Igwebu lethusiiyinsimbi enezimbobo kakhulu, engasindi eyakhiwe ngemicu yethusi exhumene. Lesi sakhiwo esiyingqayizivele sisinika izinto eziningi eziphakeme ezisihlukanisa nethusi eliqinile lendabuko. Kokunye, indawo yayo ephezulu nesilinganiso sevolumu iyenza ibe ikhandidethi elihle kakhulu labashintshisi bokushisa nezinhlelo zokuphatha ezishisayo. Ikhono layo lokukhipha ukushisa ngendlela efanele liyenza ibe into efanelekile kumadivayisi kagesi, lapho ukuphathwa kwe-thermal kuyindaba eyinhloko.

Ukwengeza, i-porous nature ye-foam yethusi iphinda iyenze ibe yisinqumo esihle kakhulu sezinhlelo zokuhlunga. Inethiwekhi yayo yezimbotshana ezixhumene ivumela uketshezi ukuthi ludlule kahle ngenkathi ibamba izinhlayiya nokungcola, okuyenza ibe into efanelekile yezinhlelo zokuhlunga amanzi nomoya. Lokhu kungaba nomthelela omkhulu ekuthuthukiseni ukufinyelela emanzini ahlanzekile nomoya emazweni asathuthuka nasezimeni zezimboni lapho ukuhlunga kubalulekile.

Ngaphezu kwezakhiwo zayo ezishisayo nezokuhlunga,igwebu lethusifuthi ikhombisa izakhiwo ezinhle kakhulu zemishini. Isilinganiso sayo esiphezulu samandla nesisindo siyenza ibe yinto ekhangayo yezinhlelo zokusebenza zesakhiwo lapho ukunciphisa isisindo kubaluleke kakhulu. Lokhu kungase kube nomthelela omkhulu ezimbonini ezifana ne-aerospace nezimoto, lapho ukwehlisa isisindo kungathuthukisa ukusebenza kahle kukaphethiloli nokusebenza.

Izicelo ezingaba khona ze-foam yethusi azikhawulelwe kulezi zindawo. Inhlanganisela yayo eyingqayizivele yezakhiwo futhi iyenza ibe ikhandidethi elikhangayo lamadivayisi wezokwelapha, i-catalysis kanye nokugcinwa kwamandla. Ukuguquguquka kwalolu hlelo lokusebenza kuvula umhlaba wamathuba wokuqamba izinto ezintsha kanye nentuthuko ezimbonini ezahlukahlukene.

Esinye sezici ezijabulisa kakhulu ze-foam yethusi amandla ayo okusimama. I-Copper iyinto ekwazi ukuphinda isetshenziswe kabusha, futhi ukukhiqizwa kwegwebu lethusi kungafinyelelwa ngokusebenzisa izinqubo ezinobungani bemvelo. Lokhu kusho ukuthi ukwamukelwa okusabalele kwegwebu lethusi kunganciphisa kakhulu umthelela wendawo, kukwenze kube inketho ekhangayo ezinkampanini ezifuna ukuthuthukisa iziqinisekiso zazo zokusimama.

Njenganoma iyiphi into entsha, ukwamukelwa okwandile kweigwebu lethusikusenezinselele okufanele zinqotshwe. Lokhu kufaka phakathi izindaba ezifana nezindleko, ukulinganisa kanye nokuthuthukiswa kwenqubo yokukhiqiza engakhiqiza igwebu lethusi ngobuningi. Kodwa-ke, izinzuzo ezingaba khona zalesi sihloko zibalulekile, futhi abacwaningi nabaholi bezimboni basebenza ngenkuthalo ukubhekana nalezi zinselele futhi balethe igwebu lethusi phambili ekusungulweni kwezinto.

Ngokufigqiwe,igwebu lethusiimele intuthuko eguquguqukayo ngempela kwisayensi yezinto. Inhlanganisela yayo eyingqayizivele yezinto ezishisayo, ezomshini nezokuhlunga, okuhambisana namandla ayo okusimama, kuyenza iguqule umdlalo ezimbonini eziningi. Njengoba ucwaningo nentuthuko kule ndawo iqhubeka nokuthuthuka, silindele ukuthi izicelo eziningi ezithokozisayo zegwebu lethusi zivele, ziphinde ziqinise isikhundla salo njengomdlali obalulekile ezintweni zesikhathi esizayo.
