Vim li cas cov ntses ntab ntab pellet ua tshuab tso tawm muaj cov khoom siv raw khoom? Ua thiab daws

 

Thaum lub sij hawm noj cov khoom noj tas mus li, tshwj xeeb tshaj yog tom qab lub sijhawm ua haujlwm ntev,floating ntses pub pellet extruder tshuabtej zaum yuav pib tsim pellets nrog qhov loj me, ntom, thiab cov duab tsis sib xws. Qhov teeb meem no feem ntau tshwm sim los ntawm kev sib xyaw ntawm cov khoom siv raw tsis sib xws, teeb meem khoom siv, thiab cov txheej txheem tsis ruaj khov. Ib txoj hauv kev daws teeb meem kev teeb tsa yuav pab rov ua kom cov zis zoo ib yam sai

 

 

Vim li cas kuv cov ntses ntab ntab pellet txiag tshuab tsim cov khoom siv tsis tau nthuav dav?

• Cov khoom nyoos yog ntxhib dhau los yog muaj cov impurities
• Kub los yog chav siab tsis txaus
• Screw ceev los yog pub mis tsis zoo sib xws
• Cov khoom siv hnav lossis tuag thaiv

Kev daws:
Optimize raw cov ntaub ntawv, stabilize kub thiab siab, kho cov txheej txheem tsis, thiab tswj cov cuab yeej tsis tu ncua.

 

I. Cov tsos mob ntawm Raw Material Residues

Tej Cim Cim

• Unexpanded hais los yog hmoov nyob rau hauv tiav pellets
• Hard residues txawv txawv ntawm cov pellets ib txwm
• Tuag qhov blockage thiab txo tus nqi tawm
• Nce lub cev muaj zog tam sim no thiab txawv txav chamber nrov

⚠️ Yog tias seem ntau dhau5%, cov khoom feem ntau ua tsis tau zoo cov qauv thiab yuav tsum tau reprocessing los yog scrapping.

II. Cov Uas Tseem Ceeb ntawm Cov Khoom Siv Hauv Extruder Discharge

1. Kev ua cov khoom nyoos tsis txaus

• Particle loj loj heev → cua sov tsis txaus thiab gelatinization
• Impurities (pob zeb, khib nyiab) → tsis tuaj yeem nthuav
• Moisture too high (>15%) → clumping thiab cua sov tsis sib xws

👉 Qhov tshwm sim:
Cov khoom siv raw tawm ntawm lub tshuab yam tsis muaj kev nthuav dav

✅ Kev daws:

• Sib tov cov khoom rau20-40 mesh
• Tshem tawm impurities ua ntej noj
• Khaws noo noo ntawm12%–15%

2. Tsis txaus kub lossis siab

• Chamber kub hauv qab no150 degree
• Chav siab hauv qab no0.3 MPa rau
• Tsawg ntsia hlau ceev → lub sij hawm nyob luv luv

👉 Qhov tshwm sim:
Tsis tiav gelatinization → unexpanded residue

✅ Kev daws:

• Khaws qhov kub thiab txias ntawm150-180 degree
• Khaws lub siab ntawm qhov chaw0.3-0.5 MPa
• Kho cov ntsia hlau nrawm rau lub sijhawm ua haujlwm txaus

3. Cov khoom siv hnav lossis thaiv

• Hnav ntsia hlau thiab chim → txo shear thiab compression
• Tuag qhov blockage → ntws tsis sib xws
• Manifold blockage → cov khoom siv tsis zoo

👉 Qhov tshwm sim:
Qee cov khoom siv hauv qab - ua tiav lossis overheated

✅ Kev daws:

• Hloov cov khoom hnav tsis tu ncua
• Ntxuav lub qhov tuag thiab cov kab noj
• Xyuas kom cov khoom ntws zoo

4. Cov txheej txheem tsis raug Parameter nqis

• Kev pub mis ntau dhau → lub sijhawm ua haujlwm tsis txaus
• Tsis sib npaug los yog tsis txaus additives → tsis zoo expansion
• Cov cua txias ua haujlwm tsis zoo → overheating lossis cua sov tsis sib xws

👉 Qhov tshwm sim:
Inconsistent expansion thiab residue tsim

✅ Kev daws:

• Sib npaug pub tus nqi nrog cov ntsia hlau ceev
• Xyuas kom muaj kev sib xyaw ua ke ntxiv
• Ua kom ruaj khov qhov kub thiab txias

III. Cov kev daws teeb meem zoo thiab kev ntsuas kom zoo

1. Raw Material Optimization

• Xyuas kom zoo ib yam particle loj thiab ya raws
• Ua raws li kev soj ntsuam cov khoom siv nruj
• Tsim kom muaj kev ntsuam xyuas zoo ua ntej ntau lawm

 

---

2. Txheej txheem Parameter Control

• Preheat lub tshuab ua ntej pib
• Saib xyuas qhov kub thiab txias tsis tu ncua
• Kho qhov ntsuas dynamically raws li tus cwj pwm ntawm cov khoom siv

 

---

3. Cov cuab yeej tu thiab tu

• Ntxuav chamber, tuag taub hau, thiab manifold tom qab txhua qhov khiav
• Tshawb xyuas cov ntsia hlau thiab lub thoob hnav tsis tu ncua
• Tshem cov blockages tam sim ntawd

 

---

4. Txheej txheem tswj thiab Standardization

• Standardize raw khoom piv thiab ua tsis
• Calibrate kub thiab siab sensors tsis tu ncua
• Qhia cov neeg ua haujlwm kom ua raws li cov txheej txheem sib xws

 

FAQ

Q1: Vim li cas thiaj muaj cov khoom tsis ua tiav hauv kuv cov ntses pub pellets?

Vim tias qhov kub tsis txaus, kev npaj khoom tsis zoo, lossis lub sijhawm extrusion tsis txaus.

Q2: Dab tsi yog qhov zoo tshaj plaws particle loj rau ntab ntses noj pellet txiag tshuab?

Feem ntau 20-40 mesh rau cov cua sov thiab nthuav dav.

Q3: Cov dej noo siab puas tuaj yeem ua rau muaj teeb meem residue?

Yog lawm, noo noo tshaj 15% tuaj yeem ua rau clumping thiab tsis tiav gelatinization.

Q4: Yuav ua li cas kho cov teeb meem residue sai sai?

Kho qhov kub thiab txias, xyuas cov khoom siv raw, thiab ntxuav cov tuag.

Q5: Yuav ua li cas tiv thaiv residue nyob rau hauv lub sij hawm ntev?

Siv cov khoom siv raw zoo ib yam, tswj cov cuab yeej tsis tu ncua, thiab ua cov txheej txheem txheej txheem.
