Sodium Alginate rau Fibers

 

 

 

Alginic acid fibers yog tsim los ntawm extracting alginic acid sodium thiab siv ntub spinning tshuab. Lawv yog ib hom biodegradable regenerated cellulose fiber ntau. Cov tuam txhab textile tau tsim algal fibers thiab tsim qee cov khoom siv algal fiber ntau. Cov khoom no tsis tsuas yog ua tau raws li tib neeg cov kev xav tau rau cov khoom siv ua haujlwm xwb, tab sis kuj tseem txo qis qhov tsis txaus ntawm cov khoom siv fiber ntau.

 

Kev siv cov khoom siv algal fiber ntau tuaj yeem ua lub luag haujlwm ntxiv hauv kev tiv thaiv ib puag ncig. Txhua zaus siv cov khoom siv biodegradable fiber ntau, kev siv cov khoom siv tsis zoo biodegradable chemical fiber yog txo, yog li txo qhov kev puas tsuaj ib puag ncig thiab tiv thaiv lub ntiaj teb zoo dua uas peb vam khom kom muaj sia nyob.

 

 

1. Lub hauv paus ntsiab lus tseem ceeb: Txoj kev ntub dej spinning

Kev tsim cov alginate fibers feem ntau yog siv cov txheej txheem "ntub spinning", uas yog raws li ionic exchange gel khoom ntawm alginate.

Cov ntaub ntawv raw:Soluble alginate sodium.

Spinning pab:Dissolve alginate sodium nyob rau hauv dej los tsim ib tug viscous thiab uniform spinning tov.

Coagulation:Calcium chloride tov.

Tsim mechanism:Thaum cov alginate spinning tov yog extruded los ntawm spinneret thiab cov kwj zoo nkag mus rau hauv cov coagulation tov uas muaj calcium ions, sodium ions yuav instantly pauv nrog calcium ions. Cov calcium ions ua raws li tus ntoo khaub lig- sib txuas cov neeg ua haujlwm thiab tsim kom muaj lub zog ionic sib txuas ntawm cov alginate molecules, yog li ua kom cov kua dej tsis sib haum rau hauv dej - calcium alginate gel fibers tsis soluble.

 

2. txheej txheem ntws

Ua tiav alginate fiber ntau lawm kab feem ntau muaj cov kauj ruam hauv qab no:

Kauj Ruam 1: Kev npaj cov tshuaj spinning

1) Cov txheej txheem tawg: Maj mam ntxiv siab -purity alginate particles rau hauv dej, thiab nyob rau hauv cov xwm txheej ntawm nplawm thiab nruab nrab cua sov, ua kom lawv yaj tag los ua ib qho kev sib xws, pob tshab thiab npuas - dawb viscous tov.

2) Pom thiab degassing: Cov tshuaj tau pom zoo kom tshem tawm cov impurities thiab tau txais kev kho lub tshuab nqus tsev kom ntseeg tau cov txheej txheem kev ruaj ntseg thiab fiber ntau.

 

Kauj Ruam 2: Cov txheej txheem ntub dej spinning

3) Spinning txheej txheem: Cov tshuaj spinning yog raug xa mus rau lub tshuab spinning (ib lub phaj hlau nrog ntau qhov me me) los ntawm lub twj tso kua mis ntsuas. Cov tshuaj spinning yog nyem tawm los ntawm lub qhov ntawm spinning net, tsim ntau cov kua dej zoo heev.

4) Cov txheej txheem Solidification: Cov kua dej nyem tam sim ntawd nkag mus rau hauv calcium chloride solidification tank. Tsis pub dhau ob peb vib nas this, ib qho kev sib pauv ion tshwm sim rau ntawm qhov chaw thiab sab hauv ntawm cov kua dej, ua rau cov kua dej no ua rau cov alginate gel fibers.

5) Tom qab tawm hauv qhov kev daws teeb meem, cov fibers tau qis qis kom tso cai rau cov saw hlau molecular kom ua raws li cov kev taw qhia fiber ntau, yog li ua kom lub zog thiab tawv ntawm cov fibers.

 

Kauj Ruam 3:

6.) Ntxuav: Cov fibers uas ntws tawm ntawm cov kua coagulation muaj ntau cov calcium ions thiab chloride ions. Yog li ntawd, lawv yuav tsum tau ntxuav ntau zaus nrog dej sov kom txog thaum lawv ncav cuag lub xeev nruab nrab.

7.) Cov txheej txheem ziab: Cov fibers ntxuav tau qhuav hauv qhov cub kom qhuav kom tshem tawm cov dej noo, ua rau cov calcium alginate fibers qhuav.

8.) Wrapping: Cov fibers qhuav yog qhov txhab rau ntawm lub bobbin los ua ib pob fiber ntau.

 

Kauj Ruam 4:

9.) Ion Txauv: Nyob ntawm cov ntawv thov zaum kawg, cov alginate fibers qhuav tuaj yeem muab tso rau hauv lwm cov ntsev tov rau kev sib pauv ion. Piv txwv li, immersing lawv nyob rau hauv ib tug sodium chloride tov yuav ua rau lawv ib nrab reconvert mus rau alginate sodium fibers (nrog rau cov dej muaj zog nqus dej). Muab lawv tso rau hauv cov kev daws teeb meem uas muaj cov nyiaj, zinc, lossis lwm yam ions yuav ua rau tsim cov alginate sodium fibers nrog cov tshuaj tua kab mob.
