Indlela Yokuhlola I-Xanthan Gum

1. Sukuhlolwa kokuqina

Thatha isampula ye-1 g, kancane kancane uthele ku-beaker equkethe amanzi angu-100 ml, imizuzu engu-15, qaphela ukuthi ufake ibha yokugubha emanzini, kancane kancane uvule i-blender ukusheshisa i-200 r / min, ingancibilika ngokuphelele ngemva kwemizuzu engu-25, ngokwendlela engenhla yokuthi amasampula awancibiliki ku-ethanol, i-acetone noma i-ethyl ether.

2. Gel experiment

Faka amanzi angu-300 ml kubhekhani ongu-500 ml, ushise kuqala kufike ku-80 ℃, vula i-blender ukusheshisa u-200r/min,Ukugqugquzela futhi wengeze isampula elomile elingu-1.5g kanye ne-1.5g yesikhonyane se-beangum.lapho ingxube ibe isixazululo, Qhubeka ugovuze imizuzu engaphezu kuka-30.(izinga lokushisa lamanzi alikho ngaphansi kuka-60 ℃ ngesikhathi sokunyakazisa). Yeka ukunyakazisa, ukupholisa okungenani amahora angu-2 ekamelweni lokushisa, lapho izinga lokushisa lehla ngo-40 ℃, kwakheka into yejeli.Ngokwendlela engenhla lokho kulungiselelwa kwe-1% Isixazululo sesampula ngokuphambene, ungafaki ushingamu wezinkumbi, ngaphandle kweglue.

3.i-viscosity

3.1 Tinsimbi 

Imitha ye-viscosity ejikelezayo yenkundla ye-Brook noma okunye ukusebenza okufanayo.

3.2Tisimo

a) Uhlobo lwerotha: 3

b) Isivinini se-rotor: 60 r/min

c)Izinga lokushisa lokulinganisa:24 ℃ ~ 25 ℃

3.3 Izinyathelo zokuhlaziya

3.3.1 Ukulungisa isisombululo esiqukethe isampula engu-1% no-1% we-potassium chloride.

a)Ngephepha lokukala elihlanzekile, elomile ngokulandelana kwamasampula asuka ku-1.5 g kanye ne-potassium chloride (enembile iye ku-0.01 g), exutshwe ngokulinganayo;

b) Ukulinganisa u-300 ml wamanzi acwecwe ebhodweni elingu-400 ml

c)Thatha ibhika elingenhla namanzi ngaphansi kwe-blender, vula i-blender, ugovuze isampula yengxube kancane kancane umjove oketshezini olunyakazayo naphakathi kwengilazi yamanzi, bese uqala ukubeka isikhathi, 800 r/min amahora amabili, ugqugquzela izinga lokushisa elingu-24 ℃ ~ 25 ℃;

d)Yeka ukunyakazisa, thatha inkomishi, nenduku yokunyakazisa noma ezinye izinto ezifanayo isixazululo saphezulu naphansi izikhathi ezimbalwa.

3.3.2 Ukuzimisela

Thatha inani elifanele lesixazululo sesampula esingu-1% kanye nesisombululo esingu-1% se-potassium chloride, faka uhlobo lwe-beaker engu-100 ml, ukuzimisela ezimweni ezinqunyiwe.

4.Amanani wamandla we-shear

4.1 Indlela yokunquma

Ngokwesinyathelo sesi-3, ngokulandelana inani le-viscosity le-3 rotor speed kuya ku-6 r/min kanye ne-60 r/min,

4.2 Imiphumela yokubala

Amanani wamandla e-shear abalwe ngohlobo (1) :

N=η1/η2 …………………… (1)

Uhlobo:

N - inani lokusebenza kwe-shear;

η1 – i-viscosity yenani elinejubane elingu-6 r/min, iyunithi ye-centipoise (cP);

η2- i-viscosity yenani elinejubane elingu-60 r/min, iyunithi ye-centipoise (cP);

5.Ukuncipha kwesisindo esomile

5.1 Umgomo

Ukomiswa kwesampula kuya esisindweni esingaguquki ngaphansi kwesimo sezinga lokushisa elithile, bala ikhwalithi yezinto ezilahlekile.

5.2 Ithuluzi

a) Ibhodlela lengilazi elinesisindo: ngaphakathi ububanzi 60 ~ 70 mm, ukuphakama ngezansi 35 mm.

b)I-ovini yokushisisa kagesi ehlala ishisa

5.3 Izinyathelo zokuhlaziya

Faka ibhodlela lesisindo ku-105 ℃ + 1 ℃ kuhhavini owomile imizuzu engama-30, isisindo esingaguquki. ibhodlela lesisindo,Ibhodlela lesisindo se-Cargo ulifake kuhhavini,Vula ikepisi nezigqoko zamabhodlela kuhhavini,Ukoma ngaphansi kuka-105 ℃ + 1 ℃ amahora angu-2,Vula uhhavini,Mboza ibhodlela lesisindo ngesampula ngokushesha,Ukupholisa kuze kufike ezingeni lokushisa ekamelweni umshini wokomisa, isisindo esihlala njalo, Ngokokunciphisa ikhwalithi kanye nesampula yesibalo sokubala ukungabi nasisindo okomile.

5.4 Imiphumela yokubala

Ingxenye yesisindo esomile sokungabi nesisindo esibalwa ngohlobo (2) :

X=[(m1-m2)/m]×100………………………(2)

Uhlobo:

X - ingxenye eyomile yesisindo somzimba, %;

m1 -Ikhwalithi yebhodlela lesisindo kanye nesampula ngaphambi kokoma, iyunithi iyigremu (g);

m2 – Ikhwalithi yebhodlela lesisindo kanye nesampula ngemva kokumiswa, iyunithi igremu (g);

m – izinga lesampula, iyunithi igremu (g).
