Halaye Huɗu Masu Muhimmanci na Gilashi
1. Isotropy
Gilashi shinekayan isotropic, ma'ana yana da halaye iri ɗaya a duk hanyoyi.
-
Ƙarfi, tsarin roba, faɗaɗa zafi, ƙarfin wutar lantarki, ma'aunin haske, da ƙarfin lantarki suna ci gaba da kasancewa iri ɗaya ba tare da la'akari da alkibla ba.
-
Sabanin haka, kayan lu'ulu'u galibi suna nuna anisotropy dangane da yanayin.
-
Duk da haka, idan akwai damuwa ta ciki, isotropy na iya katsewa, wanda ke haifar da abubuwan da suka faru kamar birefringence.
Riba:Wannan isotropy yana sa gilashi ya zama abin dogaro kuma mai karko a fannoni kamar na gani, marufi na abinci, da kuma adana sinadarai.
2. Ƙarfin narkewa
Gilashi yana cikin waniyanayin da ba ya canzawa.
-
Daga mahangar thermodynamic, matakin kuzarinsa ya fi na ƙarfe mai ƙarfi na kristal.
-
Daga mahangar motsi, saboda tsananin dankonsa a zafin ɗakin, ba zai iya canzawa zuwa lu'ulu'u ba.
-
Sai a wasu yanayi, idan aka shawo kan shingen makamashin kunnawa don lu'ulu'u, gilashin zai iya lu'ulu'u.
Riba:Ƙarfin narkewar gilashi yana ba shi kyakkyawan kwanciyar hankali na dogon lokaci, yana ba shi damar kiyaye kaddarorinsa a ƙarƙashin yanayin ajiya na yau da kullun. Wannan shine ɗayan manyan dalilan da yasa kwantena na gilashi suka dace don adana abinci da abin sha.
3. Ci gaba da Canjin Halaye da Siffofi
Tsarin gilashin na iya bambanta akai-akai a cikin wani takamaiman iyaka, kuma halayensa suna canzawa daidai gwargwado.
-
Ba kamar daskararrun kristal ba, waɗanda ke buƙatar daidaitattun rabon atomic, gilashi yana ba da ƙarin sassauci a cikin tsari.
-
Ta hanyar daidaita abubuwan da ke cikin gilashin, gilashi zai iya samun halaye daban-daban, kamar babban haske, juriya ga acid da alkali, ko kuma ingantaccen juriya ga girgizar zafi.
Riba:Wannan sassaucin yana sa gilashi ya dace da aikace-aikace daban-daban, dagakwalaben ruwan inabi da kwalaben abincizuwa ga kayan aikin gani da na lantarki masu ci gaba.
4. Ci gaba da Canji Tsakanin Tauri da Narkewa
Gilashi yana yin wanisauyi a hankalitsakanin yanayin ƙarfi da narkewa.
-
Kayan lu'ulu'u suna taurare a yanayin zafi mai ƙayyadadden lokaci, suna nuna canje-canje kwatsam a halayensu.
-
Amma gilashi ba shi da wani kaifi na narkewar abinci. Madadin haka, yana laushi a kan yanayin zafi, wanda aka sani da zafin jiki,kewayon laushi.
-
A cikin wannan kewayon, yana canzawa daga nakasar filastik zuwa nakasar roba ba tare da samar da sabon matakin lu'ulu'u ba.
Riba:Wannan sauyi a hankali yana sauƙaƙa sarrafa gilashin da kuma siffanta shi zuwa nau'ikan kwantena iri-iri, kamarkwalaben giya, kwalaben abin sha, kwalban kayan ƙanshi, kwalban zuma, da gilashin da aka keɓance.
Kammalawa
A taƙaice, an bayyana gilashi da muhimman halaye guda huɗu:
-
Isotropi- halaye iri ɗaya a duk hanyoyi.
-
Daidaitowar metabolism- rashin kwanciyar hankali a yanayin zafi amma kuma yana da kwanciyar hankali a yanayin zafi.
-
Ci gaba da bambancin abun da ke ciki da kaddarorin- sassauƙa da kuma customizable.
-
Ci gaba da sauyawa tsakanin yanayin tauri da ruwa- sauƙin siffantawa da sarrafawa.
Duk wani abu da ya cika waɗannan muhimman siffofi guda huɗu, ba tare da la'akari da sinadaran da ke cikinsu ba, za a iya ɗaukarsa a matsayin gilashi. Fahimtar waɗannan abubuwan na musammankaddarorin gilashiba wai kawai yana zurfafa ilimin kimiyya ba, har ma yana nuna dalilin da yasa gilashi abu ne mai amfani ga rayuwar yau da kullun da masana'antu na zamani.
