Yog vim li cas "Rinsing" feem ntau xaus li tua lub ncoo
Peb pom qhov no txhua lub sijhawm.
Tus neeg siv tau txais me ntsis ntawm lint ntawm lub ncoo, coj nws mus rau hauv lub dab dej, thiab khiav hauv dej. Nws zoo nkaus li huv. Nws xav tias ntub. Tab sis los ntawm kev sib tham tom ntej, nws tsis lo, thiab tus neeg mob pib yws txog "sting."
Thaum lub sijhawm ntawd, tib neeg xav tias lub ncoo yog "siv." Feem ntau, nws tsis yog. Nws nyuam qhuav ntxuav txoj kev tsis ncaj ncees lawm.Qhov teeb meem tsis yog av. Nws yog qhov dej ua rau gel.
Yuav ua li cas tshwm sim thaum koj siv kais dej
① Osmotic Imbalance (Qhov twg nws mus tsis ncaj ncees lawm)
Hydrogel tsis yog "cov khoom ntub dej." Nws yog ib tug tuned polymer network nrog ib tug tshwj xeeb ionic tshuav nyiaj li cas.
Cov dej kais dej tsis phim qhov sib npaug. Tsis txawm nyob ze. Thaum koj yaug lub ncoo, dej tsis yog zaum ntawm qhov chaw; Nws rushes mus rau hauv lub gel kom sib npaug ntawm cov concentration.
- Qhov tshwm sim:Cov qauv polymer softens thiab dhau - swells.
- Qhov Failure:Lub gel poob nws sab hauv tuav (cohesion). Qhov "dawb daim txhuam cev" zoo li cov neeg siv piav qhia? Qhov ntawd yog twb ua tsis tiav gel.
② Vim li cas nws thiaj pib Sting
Tom qab rinsing, qhov chaw chemistry tsis ruaj khov. Tam sim no tsis kis tusyees hla lub thaj ntxiv lawm. Hloov chaw, nws concentrates -feem ntau nyob ze ntawm lub connector los yog ntawm ib qho chaw me me, tsis sib xws.
Qhov ntawd yog qhov "ntse" lossis "tom" los ntawm. Nws tsis muaj zog dua ntawm lub tshuab; nws tsuas yog phem faib thoob plaws lub interface puas lawm.
Yog vim li cas ib tug poob ntawm gel ua hauj lwm zoo dua dej
Peb tau sim qhov no ntau zaus dua li peb suav tau. Dej ua rau lub ncoosaibzoo dua; conductive gel yeej ua rau nwsua haujlwmdua.
Qhov txawv yog yooj yim:Dej dilutes. Gel restores.
Ib tug zoo conductive gel twb ion - sib npaug. Yog li es tsis txhob dej nyab cov hydrogel thiab ua rau nws o, gel integrates nrog polymer matrix.
- Qhov saum npoo rehydrates tsis poob cohesion.
- Micro- qhov khoob ntawm daim tawv nqaij thiab lint tau sau.
- Txoj kev tam sim no stabilizes tam sim ntawd.
Qhov peb pom tiag tiag hauv kev sim:Pads yaug nrog dej feem ntau pom qhov adhesion poob-tawm thaum lawv qhuav. Txawm li cas los xij, cov ntaub qhwv rov qab nrog cov tshuaj chloride- sib npaug ntawm cov khoom nruab nrab tswj cov qauv thiab rov qab siv tau adhesion rau ntau lub voj voog ntxiv. Nws tsis yog ib qho kev txhim kho tas mus li, tab sis nws yog kev rov ua haujlwm engineering.
Yog tias koj xav tau Pads kawg
Tsis nco qab cov lus qhia "tso nrog dej". Qhov ntawd tau sau rau kev yooj yim, tsis yog rau kev ua haujlwm. Nov yog qhov ua tau zoo hauv kev siv tiag tiag:
- Yog tias muaj lint:Tsis txhob ntxuav tag nrho lub ncoo. Tsuas yog tshem cov khib nyiab hauv zos nrog cov damp, lint -dawb ntaub.
- Yog tias adhesion poob:Ntxiv cov txiv laum huab xeeb - qhov loj ntawm cov gel rau qhov chaw. Tsis ntau dhau -koj xav rov qab dej, tsis txhob poob dej.
- Tos ua ntej siv:Muab nws 30 vib nas this. Cia cov gel nyob rau hauv cov qauv hydrogel ua ntej siv rau ntawm daim tawv nqaij.
- Kev khaws cia tseem ceeb tshaj li kev ntxuav:Feem ntau cov ntaub qhwv tsis plam los ntawm av; lawv tsis qhuav tawm. Thaum lub hauv paus noo noo ploj mus, koj tsis nqa nws rov qab nrog cov kais dej.
Yog tias koj pom rov qab los ntawm "Dry Pads"
Nws feem ntau tsis yog lub ncoo. Nws yog li cas nws tau siv - lossis rov qab los. Yog tias koj cov neeg siv tawm tsam nrog stinging lossis luv luv lub neej voj voog, qhov kev daws teeb meem yog nyob rau hauv kev sib txuas chemistry.
