Dab tsi yog Cov Khoom Siv Diaper
Dec 01, 2022
Kev yug me nyuam ntawm txhua tus me nyuam yuav ua rau muaj kev xyiv fab heev rau tsev neeg. Cov me nyuam mos yog cov tswv cuab tseem ceeb hauv tsev neeg, yog li txhua kab lus ntawm kev siv txhua hnub xaiv rau tus menyuam yuav tsum tau soj ntsuam nruj me ntsis. Tus me nyuam daim pawm kuj yuav tsum tau soj ntsuam nruj me ntsis. Tam sim no muaj ntau hom pawm hauv khw. Yog tias lawv tsis raug xaiv kom raug, lawv yuav ua rau muaj kev phom sij loj rau tus menyuam lub plab me me. Yog li, dab tsi yog cov khoom siv pawm?
Dab tsi yog cov khoom siv pawm
Cov pawm yog cov khoom siv niaj hnub uas niaj hnub siv los ntawm cov menyuam mos, thiab yog lub npe dav dav ntawm daim pawm, daim ntawv pawm thiab rub lub ris. Cov ntaub qhwv qhuav tuaj yeem ua rau tus menyuam tsaug zog txhua hmo. Nws yog feem ntau hu ua "diaper" vim nws cov dej muaj zog.
Ntawm lawv, super absorbent resin (SAP luv luv) yog ib qho khoom siv zoo heev rau kev ua cov ntaub qhwv me me, uas yog ua los ntawm cov hmoov txhuv nplej siab thiab acrylate ua cov ntaub ntawv tseem ceeb; Qhov tseem ceeb tshaj plaws yog tias qhov nqus dej thiab khaws cia muaj peev xwm zoo heev
Kev taw qhia yooj yim
Super absorbent resin (SAP luv luv) yog cov khoom siv zoo heev rau kev ua cov pawm menyuam yaus. Nws yog ua los ntawm cov hmoov txhuv nplej siab thiab acrylate ua cov ntaub ntawv tseem ceeb. Qhov zoo tshaj plaws ntawm "diaper" yog tias qhov nqus dej thiab lub peev xwm cia tau zoo heev. Nws absorbs physiological saline 40 ~ 60 npaug ntawm nws tus kheej qhov hnyav thiab purified dej 50 ~ 100 npaug ntawm nws tus kheej qhov hnyav. Yog li ntawd, cov menyuam yaus tsis tas yuav txhawj txog kev ntub lawv lub ris thaum tso zis. Cov zis yuav ua tiav "dej" los ntawm lawv, feem ntau hu ua "cov zis ntub".
Keeb kwm ntawm daim pawm
Xyoo 1961, Soviet cosmonaut Gagarin xav tias ceev ceev thaum nws tab tom yuav nkag mus rau hauv lub tso tshuaj ntsiav, yog li nws yuav tsum tau nqis los tso zis raws cov hlab ntawm nws lub spacesuit; Nyob rau hauv tib lub xyoo, American astronaut Shepard, uas tsis muaj peev xwm mus tso rau hauv nws spaceship, kuj raug kev txom nyem los ntawm ceev ceev tso zis. Tus thawj coj hais kom nws tso zis rau hauv nws lub tsho.
Nyob rau xyoo 1980, Tang Xinyuan, "leej txiv ntawm qhov chaw suits", ib tug Suav, tau txhim kho qhov chaw nplua los daws qhov teeb meem ntawm tso zis ntawm astronauts. Nws ntxiv polymer absorbers thiab tsim ib daim ntawv diaper uas nqus tau 1400ml dej. Cov zis tsis yog ib qho teeb meem rau cov astronauts lawm. Cov cuab yeej siv tom qab tau hloov mus rau kev siv pej xeem, uas tam sim no yog "pob pawm" siv los ntawm ntau txhiab tsev neeg.
Super absorbent resin
Superabsorbent resin yog ib qho tshiab tsim cov khoom siv ua haujlwm polymer nrog cov pab pawg muaj zog hydrophilic thiab qee qhov kev sib txuas. Lub peev xwm nqus dej ntawm cov khoom siv adsorption yav dhau los, xws li ntawv, paj rwb thiab hemp, tsuas yog 15-40 lub sij hawm ntawm nws tus kheej qhov hnyav (xws li dej deionized, tib yam hauv qab no), thiab cov dej khaws cia muaj peev xwm kuj tsis zoo. . Nyob rau nruab nrab -1970s, Lub Chaw Tshawb Fawb ntawm Tebchaws Meskas Lub Tsev Haujlwm Saib Xyuas Kev Ua Liaj Ua Teb thawj zaug tau tsim ib qho super absorbent resin. Txij thaum ntawd los, ntau hom super absorbent resins tau tshwm sim. Cov resins yog insoluble nyob rau hauv dej thiab organic solvents. Lawv tuaj yeem nqus tau ntau pua mus rau txhiab zaus ntawm lawv tus kheej qhov hnyav ntawm cov dej, thiab muaj cov dej ruaj khov. Txawm tias cov dej siab yuav tsis raug nyem tawm, uas tau nyiam cov teb chaws thoob ntiaj teb. Kev lag luam muaj peev xwm ntawm super absorbent resin txuas ntxiv nthuav dav, thiab nws yog dav siv hauv kev kho mob thiab kev kho mob, cov khoom siv hauv tsev, kev tiv thaiv ib puag ncig, kev ua liaj ua teb, hav zoov thiab zaub mov kev lag luam.
yam ntxwv
1. Kev nqus dej siab: Nws tuaj yeem nqus tau ntau pua lossis ntau txhiab zaus ntawm nws tus kheej qhov hnyav.
2. Kev nqus dej siab: Txhua gram ntawm super absorbent resin tuaj yeem nqus tau ntau pua grams ntawm cov dej tsis-ionic hauv 30 vib nas this.
3. Kev tuav dej siab: dej tsis yooj yim rau kev nyem tawm ntawm cov gel tom qab nqus dej hauv qab lub siab sab nraud.
4. High expansion: lub ntim ntawm super absorbent resin gel tom qab nqus dej yuav nthuav ntau pua zaus.
5. Ammonia absorption: low cross-linked polyacrylate type super absorbent resin muaj carboxyl anions hauv nws cov qauv molecular, uas tuaj yeem nqus tau thaum ntsib ammonia thiab muaj cov nyhuv deodorization pom tseeb.
