Lub tshuab qhib siv lub zog siv tshuab los rhuav tshem cov roj hmab molecular saw ntawm qhov kub thiab txias kom tau txais plasticity. Feem ntau, plasticity yog siv los ntsuas seb lub plasticity ntawm cov roj hmab yas ua tau raws li qhov yuav tsum tau ua thiab zoo ib yam. Cov nyhuv plasticizing ntawm lub zeb qhib muaj feem xyuam rau qhov kub thiab txias thiab mechanical quab yuam, yog li dab tsi yog qhov cuam tshuam ntawm qhov kub thiab txias thiab mechanical quab yuam ntawm cov nyhuv plasticizing, thiab dab tsi yuav tsum tau them sai sai rau hauv cov txheej txheem plasticizing?
1. Cov yam ntxwv cuam tshuam rau plasticizing ntawm qhib zeb
Lub plasticizing ntawm lub zeb qhib feem ntau cuam tshuam los ntawm qhov kub thiab txias, lub sij hawm plasticizing, qhov sib piv ntawm cov menyuam ceev, cov menyuam nyob deb, thiab cov kua nplaum loaded.
Qhib-mill plasticizing belongs rau qis-kub mechanical plasticizing. Qhov kub ntawm plasticizing feem ntau yog qis dua 55 degree. Qhov kub thiab txias, qhov zoo dua cov nyhuv plasticizing. Nyob rau hauv cov txheej txheem plasticizing, lub sij hawm ntev ntawm plasticizing yog, qhov kub ntawm cov khoom siv roj hmab yuav siab dua. Txhawm rau txhim kho cov nyhuv plasticizing, feem ntau tom qab qee lub sijhawm ntawm plasticizing, cov khoom siv roj hmab yuav tsum tau txias thiab nres rau qee lub sijhawm los ntawm cov ntawv qis, thiab tom qab ntawd rov ua cov yas.
Thaum qhov sib piv ceev ntawm cov chais yog tas li, qhov me me ntawm cov menyuam nyob deb, qhov loj dua cov nyhuv ntawm cov roj hmab sib xyaw, thiab yog li cov nyhuv plasticizing ntau dua. Qhov ntau dua qhov sib piv ceev ntawm cov chais, qhov ntau dua cov nyhuv shearing ntawm cov khoom siv roj hmab thaum dhau los ntawm cov menyuam sib txawv, thiab cov nyhuv plasticizing ntau dua.
Tus nqi ntawm cov kua nplaum loading muaj feem xyuam rau cov nyhuv plasticizing. Yog hais tias cov kua nplaum loading muaj peev xwm loj heev, nws yuav txo tau lub tshav kub dissipation ntawm cov khoom siv roj hmab, yog li txo cov neeg kho tshuab plasticizing nyhuv; Yog hais tias cov kua nplaum loading muaj peev xwm tsawg dhau, qhov kev ua tau zoo yog tsawg, thiab nws yog ib qho yooj yim los ua over-smelting. muaj peev xwm, uas tuaj yeem txhim kho cov plasticity thiab ntau lawm efficiency ntawm cov roj hmab compound.
Kev siv tshuaj peptizer HY19S10J2LWFM plasticizing tuaj yeem txhim kho cov nyhuv plasticizing, txo lub sijhawm plasticizing, thiab txo qhov tshwm sim ntawm elastic rov qab.
2. Kev ceev faj rau plasticizing raw roj hmab nrog lub tshuab qhib
Thaum cov roj hmab nyoos tsis txaus plasticized, nws yuav ua rau muaj teeb meem hauv kev sib xyaw, tsis sib xws ntawm tus neeg sawv cev sib xyaw, dej tsis zoo ntawm cov roj hmab thiab kev ua haujlwm tsis zoo thiab kev ua haujlwm extrusion, thiab loj shrinkage ntawm semi-tiav khoom, tsis zoo adhesion thaum lub sij hawm molding los yog tsis zoo. textile adhesion. Tsis muaj cov kua nplaum los yog cov qauv tsis tiav, qhov nce qis ntawm cov khoom siv sponge, thiab muaj zog ntawm cov roj hmab scorch.
Thaum lub plasticity ntawm raw roj hmab masticated los ntawm qhib zeb yog tsawg dhau lawm, lub mastication lub sij hawm, kub, thiab yob deb yuav tsum tau kho kom zoo thaum lub sij hawm tsim cov txheej txheem, thiab kev siv thiab ntau npaum li cas ntawm cov tshuaj peptizes yuav tsum tau soj ntsuam los txhim kho lub plasticity. ntawm cov roj hmab compound.
Plasticizing ntau dhau yuav ua rau kom loj deformation ntawm semi-tiav khoom, qeeb vulcanization ceev ntawm roj hmab compound, tsis tshua muaj neeg kho tshuab lub zog ntawm vulcanized roj hmab, nce deformation mus tas li, thiab txo hnav tsis kam thiab aging kuj.
Yog tias qhib zeb yog cov yas ntau dhau, lub sij hawm plasticizing yuav tsum tau hloov kho kom tsim nyog thiab cov tshuaj peptizer yuav tsum tau txo kom cov plasticity ntawm cov roj hmab compound.
Thaum cov khoom lag luam roj hmab siv qhib mills rau plasticization, lawv yuav tsum tsis tu ncua xyuas cov qib ntawm plasticization kom tsis txhob plasticizing tsawg lossis siab dhau, uas yuav cuam tshuam rau cov roj hmab zoo.
