Iyini into evimbela ukushisa?Imithetho evamile yemishini kanye nobuchwepheshe bokufaka amapayipi, impahla yokufakwa kwe-thermal isho ukuthi uma izinga lokushisa elijwayelekile lilingana noma lingaphansi kuka-623K (350°C), i-thermal conductivity ingaphansi kuka-0. 14W/(mK) impahla.Izinto zokuvikela i-insulation ngokuvamile zilula, zixega, zinezimbotshana, futhi zine-thermal conductivity ephansi.Ngokuvamile isetshenziselwa ukuvimbela ukulahlekelwa ukushisa ezintweni ezishisayo namapayipi, noma isetshenziswe ekuqandiseni (okubuye kubizwe ngokubanda okuvamile) kanye nezinga lokushisa eliphansi (elibizwa nangokuthi i-cryogenic), ngakho-ke izinto zokuvikela ukushisa ezweni lami zibizwa nangokuthi ukugcinwa kokushisa noma izinto zokulondoloza ukushisa.Ngesikhathi esifanayo, ngenxa yesakhiwo se-porous noma se-fibrous se-thermal insulation material enomsebenzi omuhle wokumunca umsindo, ibuye isetshenziswe kabanzi embonini yezokwakha.
Izinto zokufakelwa ezishisayo zinezinkomba zokusebenza ezilandelayo.
(1) I-Thermal conductivity.Njengempahla yokufaka ukushisa okushisayo, ukuqhutshwa kokushisa kufanele kube kuncane ngangokunokwenzeka.Ngokuvamile, i-thermal conductivity kufanele ibe ngaphansi kuka-0.14W/(mK).Njengesisetshenziswa sokushisa esishisayo sokulondoloza amakhaza, isidingo sokuhamba kwe-thermal siphezulu.
(2) Ukuminyana ngobuningi, isisindo esiyivelakancane sezinto zokufakelwa-ngokujwayelekile kufanele sibe sezingeni eliphansi, ngokuvamile izinga lokushisa lincane, kodwa ngesikhathi esifanayo amandla omshini nawo azoncishiswa, ngakho-ke ukukhetha okufanele kwenziwe. .
(3) Amandla omshini.Ukuze uvimbele ukufakwa kwe-thermal insulation ukuthi ingakhubazeki noma yonakaliswe ngaphansi kwesisindo namandla ayo, amandla ayo okucindezela akufanele abe ngaphansi kuka-3kg/cm.
(4) Izinga lokumuncwa kwamanzi.Ngemuva kokuthi izinto zokushisa ezishisayo zithatha amanzi, ngeke zinciphise kakhulu ukusebenza kwe-thermal insulation, l Kuyingozi kakhulu ku-skimming yensimbi.Ngakho-ke, umvini kufanele ukhethe into evimbela ukushisa enezinga eliphansi lokumunca amanzi.
(5) Ukumelana nokushisa kanye nokushisa kokusetshenziswa, izinto zokuvikela ukushisa ezinezakhiwo ezihlukene zokumelana nokushisa kufanele zikhethwe ngokuya ngokushisa kwendawo okusetshenziswa kuyo."Ukusebenzisa izinga lokushisa" kuyisisekelo sokumelana nokushisa kwezinto zokushisa ezishisayo.
Ulwazi olungenhla luwulwazi olufanele mayelana nokuthi kuyini okokuvikela ukushisa nezinto eziphikisayo ezethulwa inkampani yebhodi lokuvikela umlilo.Isihloko sivela ku-goldenpower Group
