Xanthan Gum Test Method

1. Solubility test

Tora 1 g sampuli, zvishoma nezvishoma udire mubeaker ine 100 ml mvura, kwemaminitsi gumi nemashanu, chenjerera kuisa bhari mumvura, zvishoma nezvishoma vhura blender kuti ikurumidze 200 r / min, inogona kunyungudutswa zvachose mushure memaminitsi makumi maviri nemashanu, maererano nenzira iri pamusoro apa iyo samples hainyungudika mu ethanol, acetone kana ethyl ether.

2. Gel experiment

Wedzera 300 ml mvura mubeaker 500 ml, preheat kusvika 80 ℃, vhura blender kuti ikurumidze 200r/min,Kukurudzira nekuwedzera 1.5g yakaoma sampu uye 1.5g mhashu beangum.kana musanganiswa kuva mhinduro, Ramba uchimutsa anopfuura maminitsi makumi matatu.(tembiricha yemvura haina kuderera kupfuura 60 ℃ panguva yekubvongodza).Rega kubvongodza, kutonhora zvishoma kwemaawa maviri patembiricha yekamuri, kana tembiricha yadzikira mu40 ℃, kugadzira chinhu chegel. Maererano nenzira iri pamusoro iyo kugadzirira kwe1% ye sampuli mhinduro nekusiyanisa, usawedzera mhashu bhinzi chingamu, pasina glue.

3.viscosity

3.1 Tchiridzwa chake 

Brook munda inotenderera viscometer viscosity mita kana kumwe kuita kwakaenzana.

3.2Test condition

a) Rotor rotor mhando: 3

b) The rotor kumhanya: 60 r/min

c) Kuyeresa tembiricha:24 ℃ ~ 25 ℃

3.3 Ongororo matanho

3.3.1 Gadzirira mushonga une 1% sample uye 1% potassium chloride.

a) Nebepa rekuyera rakachena, rakaoma zvichiteerana zvichienderana nemasampuli kubva ku1.5 g uye potassium chloride (yakarurama kusvika 0.01 g), yakasanganiswa zvakaenzana;

b)Kuyera 300 ml yemvura yakadirwa mu400 ml beaker

c)Tora beaker iri pamusoro nemvura pasi peblender, vhura blender, simbisa musanganiswa wemusanganiswa zvishoma nezvishoma jekiseni mumvura inovhenganiswa uye pakati pegirazi remvura, uye tanga nguva, 800 r/min kwemaawa maviri, uchikurudzira tembiricha 24 ℃ ~ 25 ℃;

d)Rega kubvongodza, tora kapu, ine bhara kana zvimwe zvinhu zvakafanana up-and-down solution kakati wandei.

3.3.2 Kutsunga

Tora huwandu hwakakodzera hwe1% sampuli mhinduro uye 1% potassium chloride mhinduro, isa mumhando 100 ml beaker, kutsunga mune zvakatemwa mamiriro.

4.Kuveura masimba masimba

4.1 Nzira yekusarudza

Zvinoenderana nedanho rechitatu, zvichiteerana kukosha kwe viscosity ye3 rotor kumhanya kusvika 6 r/min uye 60 r/min,

4.2 Mibairo yekuverenga

Shear simba kukosha kwakaverengerwa nemhando (1) :

N=η1/η2 ……………………… (1)

Type:

N - shear performance value;

η1 - viscosity yekukosha nekumhanya 6 r/min, iyo unit ye ​​centipoise (cP);

η2- iyo viscosity yekukosha nekumhanya 60 r/min, iyo unit ye ​​centipoise (cP);

5.Dry uremu kurasikirwa

5.1 Nheyo

Muenzaniso wekuomesa kune uremu hunogara huri pasi pemamiriro eimwe tembiricha, verenga iyo yakarasika yemhando yemhando.

5.2 Chiridzwa

a) Girazi rinoyera bhodhoro: mukati dhayamita 60 ~ 70 mm, iyo yakakwira pazasi ye35 mm.

b)Electric kudziyisa inogara tembiricha yekuomesa oveni

5.3 Ongororo matanho

Isa bhodhoro rehuremu pa105 ℃ + 1 ℃ ovheni yakaoma kwemaminitsi makumi matatu, uremu hunogara huripo. bhodhoro rekuyeresa,Bhodhoro rekuyeresa remutoro woriisa muovheni,Vhura kepisi nemabhodhoro evhavha muovheni,Kuomesa pasi pe105 ℃ + 1 ℃ kwemaawa maviri,Vhura ovheni,Vhivha bhodhoro rekuyeresa nesample nekukasika,Kutonhora kusvika kukamuri tembiricha mukati. iyo dryer, uremu hwenguva dzose, Zvinoenderana nekudzikisa kunaka uye sampling huwandu hwekuverenga iyo yakaoma huremu.

5.4 Mibairo yekuverenga

Dry misa chikamu chehuremu chakaverengerwa nerudzi (2):

X=[(m1-m2)/m]×100………………………(2)

Type:

X - yakaoma misa chikamu chekurema,%;

m1 -The quility yekuyera bhodhoro uye sampuli isati yaoma , chikwata igiramu (g);

m2 - Iyo quility yekuyera bhodhoro uye sampuli mushure mekuoma, iyo unit igiramu (g);

m - kunaka kwemuenzaniso, chikwata igiramu (g).
