Superabsorbent Polymers (SAP): Superabsorbentpolymers yog feem ntau siv li ib nqus tau forwater thiab aqueous daws rau cov pawm, cov neeg laus incontinenceproducts, feminine hygiene khoom, thiab cov ntawv zoo sib xws.
Ntxiv rau qhov no, super absorbent polymer ua haujlwm li cas?
SAP ( Super Absorbent Polymer ) raug cais tawm ashydrogels thaum sib txuas, nqus cov kev daws teeb meem los ntawm hydrogen bonding nrog dej molecules. High cross-link density polymers nthuav tawm qis dua nqus tau muaj peev xwm thiab o, tab sis lub gel lub zog yog firmer thiab muaj peev xwm tswj tau particle zoo txawm nyob rau hauv me ntsis siab.
Tsis tas li ntawd, super absorbent polymers pab tau li cas hauv cov lim roj? Cov tseem ceeb ntawm no super absorbentpolymers lays ntawm qhov tseeb tias lawv tsim nyog rau txo cov av noo uas nkag mus rau hauv lub cav, txhawm rau tiv thaiv lub cav thiab lwm yam. tseem ceeb qhov chaw los ntawm xeb. Cov roj lim los ntawm nws tus kheej tshem tawm cov khoom txaus ntshai rau lub cav, thaum lub polymers nqus cov av noo.
Yog li ntawd, puas yog super absorbent polymer lom?
SAPs raug suav hais tias tsis yog tshuaj lom , nonsensitizing, tsis irritant thiab tsis mutagenic. Txhua yam, siv dej absorbent polymer yog ib qho zoo. Lawv tsis yog tshuaj lom thiab nyab xeeb, thiab lawv pab kom cov nappies thinner, sothere muaj pov tseg tsawg.
Cov dej ntau npaum li cas tuaj yeem nqus tau super absorbent polymer?
Cov super absorbent yuav nqus tau txog 800 npaug nws qhov hnyav hauv distilled dej . Tib yam polymer yuav nqus tau tsuas yog kwv yees li 300 npaug ntawm nws qhov hnyav hauv kais dej . Qhov no polymer yuav nqus tau tsuas yog kwv yees li 60 npaug ntawm nws qhov hnyav ntawm 0.9% sodium chloride tov.

Dab tsi yog kev siv cov saw hlau nuclear siv rau?
Nuclear chain reaction. Nuclear chain reactions yog cov tshuaj tiv thaiv uas tau txais lub zog nuclear, feem ntau los ntawm nuclear fission. Cov kev cuam tshuam ntawm cov saw hlau no yog qhov muab cov chaw tsim hluav taws xob nuclear nrog lub zog uas tom qab ntawd hloov mus ua hluav taws xob siv los ntawm tib neeg
Plaub hom polymers yog dab tsi?
Muaj plaub yam yooj yim ntawm biomacromolecules: carbohydrates, lipids, proteins, thiab nucleic acids.Cov polymers no yog tsim los ntawm cov monomers sib txawv thiab ua haujlwm sib txawv. Carbohydrates: molecules tsim los ntawm qab zib monomers. Lawv tsim nyog rau kev khaws cia hluav taws xob
Dab tsi yog super phosphate siv rau?
Kev lag luam superphosphate cov ntaub ntawv hais tias cov khoom lag luam yog txhawm rau txhim kho cov hauv paus hniav thiab pab cov nroj tsuag cov suab thaj txav mus los zoo dua rau kev ua kom sai dua. Nws txoj kev siv ntau dua yog nyob rau hauv kev txhawb nqa ntawm cov paj loj thiab ntau cov txiv hmab txiv ntoo
Dab tsi yog qhov sib npaug siv los xam tag nrho cov khoom siv hluav taws xob siv?
Cov mis uas txuas lub zog thiab lub zog yog: Zog = Lub Zog x Sijhawm. Chav tsev ntawm lub zog yog joule, lub zog ntawm lub zog yog watt, thiab chav tsev ntawm lub sijhawm yog qhov thib ob
Dab tsi yog cov khoom uas tsis yog absorbent?
Adj tsis muaj peev xwm nqus los yog nqus tau (kua) Cov ntsiab lus: nonabsorptive repellent, resistant. tsis muaj peev xwm nqus los yog sib xyaw nrog. Antonyms: nqus, nqus. muaj zog los yog muaj peev xwm los yog nyiam nqus los yog nqus tau ib yam dab tsi (kua lossis lub zog thiab lwm yam) absorbefacient, sorbefacient
