Yuav ua li cas daws qhov chaw dub thaum granulating?

 

 

Peb yuav ua li cas yog tias cov pob dub tshwm thaum lub sij hawm granulation hauv granulator?

Thaum lub sij hawm txheej txheem granulation, nws yog ib qho teeb meem tshwm sim uas cov pob dub tshwm rau ntawm cov granules pumped.

Yuav daws qhov teeb meem no li cas? Puas yog qhov tshwm sim no tshwm sim los ntawm qhov teeb meem nrog cov granulator, cov khoom siv raw, lossis lwm yam?

Tam sim noCOLOWEyuav tshuaj xyuas nws rau txhua tus.Qhov teeb meem ntawm cov pob dub thaum lub sij hawm granulation txheej txheem yog ib qho tshwm sim tsis ua hauj lwm, tshwj xeeb tshaj yog nyob rau hauv cov khoom xim thiab lub teeb xim. Nws yog feem ntau thaum lub sij hawm kawg loj-scale ntau lawm txheej txheem uas nws tau pom tias tsis muaj teeb meem nrog cov khoom ua tau zoo thiab cov khoom xim. Txawm li cas los xij, tom qab lub sijhawm dhau los, peb tau txais kev tsis txaus siab los ntawm cov neeg siv khoom, "Cov khoom tsim nyog tus nqi qis dhau, muaj cov pob dub, thiab lawv xav tau rov qab," thiab lwm yam.

Lub sijhawm no, qhov teeb meem ntawm vim li cas cov pob dub tshwm sim ua rau ntau tus phooj ywg mob taub hau.

Txhawm rau kom tsis txhob muaj kev puas tsuaj ntawm carbonization rau cov khoom yas kom ntau li ntau tau, tus yuam sij yog los tiv thaiv thiab txo qhov poob. Peb yuav tsum muaj kev nkag siab tob txog qhov ntawm carbonization thiab ua tib zoo siv cov kev daws teeb meem zoo. Peb yuav tsum nruj me ntsis tswj txhua kauj ruam hauv kev daws thiab tiv thaiv carbonization ntawm cov khoom yas.

Txhawm rau ntxuav cov carbide hauv lub tshuab sai sai, koj yuav tsum siv cov yas tawv tawv lossis cov khoom siv rov ua dua tshiab thiab ntxiv cov roj ntxhia dawb rau kev ntxuav, thiab qhov kub yuav tsum tau nce 10 ~ 15 degree. Nyob rau lub sijhawm no, lub peev xwm plasticizing ntawm me me extruder yuav tsum tau xav txog. Rau qhov loj thiab nruab nrab-qhov loj me extruders uas tuaj yeem plasticize ultra-siab molecular hnyav plastics, lawv tuaj yeem ntxuav nrog ultra-siab molecular hnyav plastics lossis lawv cov khoom siv rov ua dua ntxiv rau cov roj ntxhia dawb.

Vim hais tias ultra-siab molecular hnyav plastics kuj yog ib qho nyuaj, thiab thaum kub siab, cov khoom tu yuav soften thiab yooj yim poob tawm, uas yog conducive rau cov carbide raug coj tawm los ntawm cov yas yaj. Thaum lub sij hawm ntxuav, lub extruder lub rotational ceev hloov dua siab tshiab ntawm tsawg ceev thiab siab ceev ob peb zaug. Yog hais tias lub cev muaj zog load tseem txaus, lub extruder tuaj yeem rov ua dua thiab rov pib dua ob peb zaug thaum lub sijhawm ua haujlwm txhawm rau txhim kho cov nyhuv tu. Thaum cov carbide (dub me ntsis) hauv cov yaj yog txo qis, hloov nws nrog cov yas li niaj zaus thiab ntxuav nws kom txog thaum nws huv. Maj mam kho nws kom haum rau qhov kub thiab txias, thiab tom qab ntawd cov khoom lag luam ib txwm tuaj yeem ua tiav.

Nyob rau hauv qhov tseeb ntawm cov khoom yas, cov khoom noj khoom haus feem ntau yog cais tawm ntawm lub hauv ntej ntawm cov yas granulator, cov yas yaj hauv lub tshuab taub hau thiab lub tshuab taub hau raug tshem tawm, qhov kub ntawm txhua cheeb tsam raug kaw, thiab tom qab ntawd lub hwj chim yog muab tshem tawm. tawm. Txij li cov yas yaj muaj cov nplaum nplaum rau ntawm cov hlau, nws tsis tuaj yeem tshem tawm tag nrho nws txhua lub sijhawm. Thaum kawg, ib txheej nyias nyias ntawm cov yas yaj ua kom ruaj khov rau lub thoob thiab cov phab ntsa sab hauv ntawm lub taub hau ntawm cov neeg nkag.

Ntawm cov ntsia hlau, thaum cov cuab yeej txias txias thiab cua sov hauv cov kauj ruam tom ntej, nws nyob ntawm qhov kub thiab txias rau lub sijhawm ntev, ua rau pom tseeb thermal deterioration, maj mam tig daj thiab zooming rau hauv carbide. Raws li cov qauv kev cai, tsis muaj kev sib khi zoo ntawm ob qho kawg ntawm qhov qhib qhov tuag thiab pub chaw nres nkoj ntawm lub tshuab taub hau, uas ua rau huab cua nkag mus rau hauv lub tshuab thiab ua rau oxidation, ua rau cov yas seem hauv lub tshuab kom tiv thaiv thermal. deterioration, uas muab tej yam kev mob zoo rau carbonization.

Txij li thaum cov cuab yeej muaj cov qauv hlau, qhov thermal expansion nce ntawm nws thiab cov yas nce, thiab cov yas carbonized tau txo foaming zog tiv thaiv cov hlau. Nws yog ib qho yooj yim los sib tov hauv cov yas granulator los ntawm cov phab ntsa sab hauv ntawm lub thoob, sab hauv phab ntsa ntawm lub tshuab taub hau thiab lub qhov (socket) sab sauv ntawm cov ntsia hlau. Nyob rau hauv cov yas yaj, muaj ntau qhov chaw dub ntawm cov phab ntsa sab nrauv ntawm cov khoom, uas ua rau muaj teeb meem hluav taws kub zoo xws li qhov los yog qhov dej.

Tom qab lub sijhawm ntev, cua sov yuav ua rau ntau qhov pib, thiab cov pob dub loj loj yuav yooj yim tshwm rau ntawm phab ntsa sab nrauv ntawm cov khoom yas, uas tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov khoom. Cov kev xav tau zoo, cov pob dub no yog cov carbide los ntawm thermal degradation ntawm cov yas seem hauv lub tshuab. Feem ntau, lub tshuab ntxhua khaub ncaws yog siv los txuas ntxiv cov yas thiab tshem tawm cov yas yaj nrog cov xim dub. Lub sijhawm ntxuav yog ntev li 3-5 teev. Yog tias thawj lub khob yas ultra-siab yog carbonized thiab cov khoom xim thawj yog tsim, nws yuav nce ntxiv. Kev siv lub tshuab ntxhua khaub ncaws ua rau lub tshuab ntxhua khaub ncaws siv sij hawm ntev dua thiab lub tshuab ntxhua khaub ncaws ntau dua.

COLOWE ua raws li hom kev ntseeg ntawm "cia thev naus laus zis ua tiav kev tsim khoom ntse hauv kev lag luam kos duab" thiab tus nqi tseem ceeb ntawm "ua qhov sib npaug ntxaib-ntsia hlau automation". Cov khoom tseem ceeb muaj xws li co-directing parallelntxaib ntsia hlauCov cuab yeej ntse, strand granulation, filling, thiab blending forming Dej-ntiv nplhaib txiav, cua txias tuag txiav, underwater pelletizing, thiab nruam sib xyaw cov kab ntau lawm muab cov neeg siv khoom nrog tag nrho cov kev daws teeb meem rau qhov chaw tsim khoom ntse raws li cov roj hmab thiab cov yas, tsim kom muaj zog, lub zog- txuag, ruaj khov, nyab xeeb, thiab ntse tsim daim ntawv thov scenarios.
