Lub tshuab nqus tsev qub coated PVC seem ntaub txiav rau hauv me me
Lub siab polymer aqueous tov yog xa mus rau lub pre-concentrator tom qab lim tawm cov xim muab tshuaj txhuam, muab tub lim thiab lwm yam tshuaj. Kev sib xyaw ntawm ob lub xim txhaj tshuaj molding tshuab thaum lub tackifier tseem nyob hauv cov kuab tshuaj, cov tshuaj polyvinyl chloride epoxy resin tau lim tawm, thiab tom qab ntawd qhov kawg ziab yog nqa tawm hauv cov yeeb yaj kiab evaporator lossis lub tshuab ziab khaub ncaws hauv qab lub tshuab nqus tsev. . Kev ziab yog txaus, thiab cov kuab tshuaj tau xa rov qab mus rau hauv lub ntsws tom qab kev tsis txaus ntseeg. Hom kev ua no tuaj yeem cais cov PVC los ntawm PVC-coated npuag lossis nws cov khoom sib xyaw. PVC-coated npuag yog thawj zaug ntawm cov ntaub npuag txiav rau hauv me me.
Nqus txoj kev tshuab tubular reactor ntxuav 3 zaug nrog hnyav
Tom qab cov ntaub ntawv saum toj kawg nkaus tau qhuav lawm, nws raug xa mus rau lub nkoj tsho uas muaj cov kuab tshuaj xws li tetrahydrofuran, uas yog cov txheej txheem ntawm kev yuav khoom software rau txheej txheej high-pressure polyethylene fabrics. Cov kev pabcuam tau muab faib thiab sib xyaw, thiab cov khoom sib xyaw yog nplawm thiab khaws cia ntawm qhov kub thiab txias kom txog thaum lub siab-siab polyethylene yog tag nrho melted. Tom qab lub nkoj kaw lawm, ib qho roj tsawg tau qhia. Thaum sib tov, cov khoom khaws cia ntawm cov tshuaj fiber ntau yog muab rho tawm los ntawm lub tshuab lim. Lub compound yog rhuab mus rau qhov kub me ntsis hauv qab lub melting point ntawm cov kuab tshuaj, uas, txawm hais tias nws tsis tuaj yeem yaj PVC, ces tau ntim nrog cov dej daws rau hauv cov tso tsheb hlau luam, thiab cov tubular reactor tau ntxuav 3 zaug nrog cov kuab tshuaj, tab sis tuaj yeem ua tau. tag nrho (los yog tseem ceeb) tshem tawm ntawm cov kuab tshuaj tov ua ke.
Qhov kub siab ntawm lub tshuab nqus tsev tsim lub tshuab puas tsuaj rau qhov chaw ntawm cov qauv roj hmab
Qhov nce ntawm qhov kub yuav ua rau cov viscosity ntawm cov roj txo. Yog tias qhov xwm txheej zoo li no tshwm sim, ces nws yuav txo qhov kev ua tau zoo ntawm txhua lub tshuab ntawm lub tshuab txhaj tshuaj molding. Vim qhov txo qis hauv viscosity, hnav qib ntawm cov khoom hauv lub lubricated ib feem kuj yuav nce ntxiv, uas yuav ua rau muaj teeb meem hnav. Qhov kub ntau dhau tuaj yeem ua rau cov khoom siv roj hmab puas. Vim hais tias yog tias qhov kub thiab txias dhau lawm, qhov kev laus ntawm cov roj hmab yuav nrawm dua, yog li nws txoj kev sib khi yuav txo qis, kev pabcuam lub neej kuj yuav txo qis, thiab kev sib tsoo yuav tshwm sim. Yog tias qhov kub thiab txias dhau lawm, nws kuj tseem tuaj yeem tshwm sim los ntawm kev txhaws ntawm cov raj xa dej, xws li kev txhaws ntawm cov ntxaij lim dej thiab qhov thaiv ntawm cov cua txias ntauwd.
