Qhov zoo li qub ntawm cov khoom khov-qhuav yog cov xim sib xws, qhov ntim thiab cov duab ntawm cov khoom yog qhov pib tsis hloov ua ntej thiab tom qab khov-qhuav, thiab cov qauv spongy loj yog tsim. Yog tias muaj cov plhaub tawv tawv, tawg, hollows thiab tawg, lawv tag nrho cov duab txawv txav thiab cov khoom tsis tsim nyog.
Cov khoom khov-dried yog tsim nyog rau cov laj thawj hauv qab no:
A, Lub sij hawm ziab yog luv dhau los yog qhov kub thiab txias qis, los yog ob qho tib si. Yog tias qhov ntsuas kub thiab ntsuas lub tshuab nqus tsev yog qhov qub, thiab ntau qhov sib law liag ntawm cov khoom khov-qhuav tsis tsim nyog, lub sij hawm ziab yuav tsum tau ncua thiab qhov kub sublimation yuav tsum tau nce ntxiv yog tias ua tau. Yog tias cov khoom lag luam yav dhau los zoo, ces nws yuav tshwm sim los ntawm kev ntim khoom yuam kev, qhov tsis raug ntawm qhov khov, thiab lub tshuab nqus tsev tsis raug, thiab lub sijhawm ziab yuav tsum tau txuas ntxiv kom tsim nyog, lossis nws yuav yog qhov tseeb sublimation kub qis dua qhov teeb tsa. sublimation kub vim qhov ntsuas kub tsis raug.
B, Tus nqi khov yog ceev heev. Cov nplej yog zoo heev kom qeeb tus nqi sublimation. Vim qhov txo qis ntawm lub peev xwm filling, los yog lub sij hawm txias ntawm lub thawv khoob yog ntev dhau lawm, qhov kub thiab txias yog qis heev, tus nqi khov yuav nrawm dua, cov nplej yuav zoo dua, thiab kev khiav tawm ntawm cov dej vapor yuav raug cuam tshuam. Yuav tsum tau ncua lub sij hawm kom qhuav, los yog txo tus nqi khov.
C, Lub freezing tsis tiav, yog li ntawd qhov sib txawv los yog huab cua tsis kam yog tsim los ntawm cov khoom khov thiab lub thawv phab ntsa kom txo tau cov cua sov hloov. Vim qhov khov tsis tiav, evaporative freezing tshwm sim thaum lub tshuab nqus tsev sublimation, uas txo qhov ntim ntawm cov khoom thiab tsim qhov sib txawv ntawm cov khoom thiab cov thawv ntim, thiab cov cua sov tsis tuaj yeem hloov mus rau cov khoom. Raws li cov sublimation tshwm sim, cov dej khov nyob ib ncig ntawm cov khoom khov khov sublimates ua ntej, Ib txheej txheej insulating qhuav yog tsim los puag ncig lub thaiv khov, ua rau nws nyuaj dua rau cov cua sov kom hloov mus rau cov khoom khov, yog li lub sijhawm ziab yuav tsum tau ntev.
D, Qee cov khoom tsis tsim nyog rau ziab. Nws tuaj yeem tshwm sim los ntawm qhov sib txawv ntawm qhov kub thiab txias ntau dhau ntawm cov txee, cov tais tsis sib xws lossis cov txee kom cov khoom hauv qab ntawm cov khoom tsis sib xws, lossis cov khoom ntim tsis sib xws. Rau lub tshuab ziab khaub ncaws tsis zoo, tsuas yog txuas ntxiv lub sijhawm khov-qhuav, kom cov dej ntsiab lus ntawm cov khoom feem ntau ua tau raws li qhov yuav tsum tau ua.
