Gel ice packs, raws li cov cuab yeej ua kom txias thiab ua kom sov, ua lub luag haujlwm tseem ceeb hauv kev kho mob, kev tiv thaiv kev ua kis las, thiab lub neej txhua hnub. Lawv lub luag haujlwm tseem ceeb yog nyob ntawm kev sib koom ua ke ntawm cov khoom siv lub cev ntawm cov khoom nruab nrab ntawm cov gel nruab nrab thiab cov qauv ntim sab nraud, ua tiav qhov sib npaug ntawm qhov ntsuas kub thiab qhov yooj yim ntawm kev siv los ntawm kev tsim qauv.
Qauv thiab Txoj Cai Ua Haujlwm ntawm Gel Ice Packs
Gel ice packs feem ntau muaj peb txheej: ib txheej txheej ntawm hnav- cov khoom siv tiv taus thiab tsis muaj dej tsis zoo (xws li PVC lossis TPU), ib txheej nruab nrab ntawm cov txheej ntim dej tsis sib haum, thiab txheej txheej sab hauv uas muaj cov khoom nqus dej zoo heev. Cov gel no siv dej los ua qhov nruab nrab dispersion, tov nrog cov thickeners xws li hydroxyethyl cellulose thiab carrageenan, ua ib tug semi- cov khoom muaj zog nrog peb - cov qauv sib txuas. Thaum lub ambient kub txo, cov gel khaws cia txias zog los ntawm hydrogen bonding; conversely, nws maj mam tso cua sov. Nws cov theem hloov pauv kub yog feem ntau tswj ntawm 0℃thiab 15 degree, ua tau raws li qhov yuav tsum tau muaj rau kev nyab xeeb cryotherapy ntawm tib neeg cov ntaub so ntswg.
Kev sim cov ntaub ntawv qhia tau hais tias tom qab tau khov ntawm -18℃rau 2 teev, gel-filled ice packs tswj qhov kub thiab txias ntawm 4℃thiab 8 degree, ua tiav 30% siab dua qhov ua kom txias dua li cov ntim dej khov, thaum tsis txhob muaj kev pheej hmoo ntawm frostbite los ntawm kev sib cuag ntawm daim tawv nqaij.
Multi-Scenario Application Value Analysis
(I) Kev Kho Mob Kub Ceev
Hauv kev kho mob ntawm cov nqaij mos raug mob, gel ice packs ua rau vasoconstriction hauv zos los ntawm txias compresses, zoo txo capillary exudation txog li 42% (raws li kev tshawb fawb 2021 nyob rau hauv * Phau ntawv Journal of Sports Medicine*), yog li no relieving o thiab mob. Piv nrog rau cov dej khov crushed, nws cov yas siab tso cai rau nws ua raws li qhov sib koom ua ke (xws li lub hauv caug thiab lub luj tshib), ncua sij hawm ua haujlwm rau 40-60 feeb.
(II) Kev Tiv Thaiv Kev Ua Si
Cov kws ncaws pob kws tshaj lij feem ntau siv ua ntej- cov pob khoom txias gel rau cov leeg nqaij tom qab kev cob qhia. Cov kev tshawb fawb tau pom tias muab cov pob dej khov rau ntawm lub quadriceps rau 15 feeb tuaj yeem ua rau cov lactic acid metabolism nce los ntawm 27%, thiab thaum siv nrog cov ntaub qhwv elastic, tuaj yeem txo qhov tshwm sim qeeb ntawm cov leeg nqaij mob los ntawm kwv yees li 35%. Qee cov khoom siv siab- kawg suav nrog cov pa roj carbon activated, muab cov khoom siv tshuaj tua kab mob ntxiv.
(III) Cold Chain Transportation Supplementary Solutions
Hauv qhov kawg - mais kev xa tshuaj tiv thaiv lossis cov khoom tshiab, gel ice packs tuaj yeem ua lwm txoj hauv kev hloov cov ntaub ntawv. Thaum lub thauj khoom nce mus txog 20% ntawm lub ntim ntim, nws tuaj yeem tuav tau 4℃ib puag ncig rau kwv yees li 6-8 teev yam tsis muaj lub tub yees sab nraud, ua rau nws tsim nyog rau kev thauj khoom thauj mus los.
Technological Innovation thiab Development Trends
Cov txheej txheem niaj hnub no txhim kho gel stability los ntawm nanoscale microencapsulation tshuab. Kev taw qhia txog cov ntaub ntawv hloov pauv tshiab xws li vinyl acetate copolymer (EVA) tso cai rau cov ntim dej khov rov qab siv dua 50 zaug. Environmentally friendly products siv biodegradable cellulose gel, uas tag nrho decomposes nyob rau hauv ib puag ncig ntuj nyob rau hauv 6-12 lub hlis tom qab muab pov tseg. Hais txog kev tsim qauv ntse, qee cov tuam ntxhab tau tsim cov khoom siv hluav taws xob hluav taws xob nrog cov ntsuas kub sib xyaw ua ke, muaj peev xwm xa cov ntaub ntawv hauv lub sijhawm mus rau lub xov tooj ntawm tes ntawm Bluetooth.
Los ntawm kev kho mob yooj yim mus rau kev ua kis las, gel ice packs txuas ntxiv nthuav lawv daim ntawv thov ciam teb ua tsaug rau lawv cov txheej txheem kev ntsuas kub ntsuas. Nrog rau kev nce qib hauv cov ntaub ntawv tshawb fawb, cov khoom lag luam yav tom ntej yuav ua tiav qhov kev ua tiav tob dua hauv kev ua haujlwm ruaj khov, kev phooj ywg ib puag ncig, thiab tib neeg- kev sib cuam tshuam hauv computer, muab cov kev daws teeb meem zoo dua rau qhov kub thiab txias - qhov xwm txheej ceev.
