Cov yam ntxwv ntawm extrusion tuag rau tsheb roj hmab sealing sawb

Extrusion yam ntxwv ntawm roj hmab sealing sawb
Yuav kom nkag siab zoo txog kev paub txog roj hmab extrusion pwm, cia peb paub txog cov yam ntxwv ntawm cov roj hmab extrusion ua ntej.
1) Cov roj hmab ntxiv sib xyaw thiab plasticized los ntawm kev sib hloov ntawm cov ntsia hlau extruder kom ntseeg tau tias qhov zoo ntawm cov roj hmab extruded semi-tiav yog ntau ntom thiab sib xws;
2) Nws muaj ntau yam kev siv. Los ntawm kev hloov cov tuag, nws muaj peev xwm extrude roj hmab profiles nrog ntau yam cross-section duab thiab preformed semi-tiav khoom rau nias tuag;
3) Extruded khoom muaj kev kub ceev thiab ntau lawm efficiency, uas yog conducive rau tsis siv neeg ntau lawm;
4) Extrusion molding tsis txwv qhov ntev, thiab tuaj yeem tsim cov khoom ntev ntev uas tsis tuaj yeem molded.
Roj hmab extruder
Extrusion tuag qauv ntawm roj hmab sealing sawb
Tam sim no, roj hmab extrusion tuag tau muab faib ua ob hom, uas yog monomer roj hmab extrusion tuag thiab puas roj hmab extrusion tuag. Ob hom extrusion tuag no muaj ob qho tib si generality thiab tus kheej. Ib qho extrusion tuag feem ntau yog tsim los ntawm ib lub vaj huam sib luag nrog cov qauv yooj yim; Qhov sib xyaw extrusion tuag feem ntau yog tsim los ntawm vaj huam sib luag, cov phaj khiav, cov phaj splitter thiab cov lus qhia fiber ntau, uas yog qhov nyuaj. Cov lus dab neeg yog raws li nram no.

Kev ceev faj rau roj hmab foob extrusion tuag tsim
Feem ntau siv software tsim rau pwm tsim muaj xws li AutoCAD, Pro / E, UG, CATIA SolidWorks, thiab lwm yam. Vim tias cov khoom extrusion ntawm sealing strips tsis txwv ntev; Ntxiv mus, hom sealing sawb suav nrog tsis tsuas yog ib qho roj hmab sealing sawb (cov roj hmab ntshiab sealing sawb), tab sis kuj muaj cov roj hmab sealing sawb (composite sealing sawb ntawm cov hlau txhawb nqa); Tsis tas li ntawd, lub sealing sawb yuav nthuav tawm cov khoom siv kho tshuab nyuaj heev thaum lub sijhawm teeb tsa thiab siv, xws li cov khoom siv, geometric nonlinearity, ciam teb tsis zoo, thiab lwm yam, yog li cov txheej txheem sealing strip molding yog qhov tseeb thiab nyuaj, yog li thaum tsim pwm, them sai sai rau qhov shrinkage ntawm roj hmab ntawm cov khoom sib txawv, nrog rau cov khoom tsim thiab cov qauv sab hauv.
1) Kev ceev faj rau kev tsim ntawm monomer roj hmab extrusion tuag
Rau txhua qhov extrusion tuag, lub ntsiab lus tseem ceeb ntawm nws cov qauv tsim yog los xyuas kom meej cov qauv tsim ntawm cov seem loj thiab cov duab ntawm cov khoom extrusion. Yog li ntawd, cov nram qab no 6 yam yuav tsum tau xav txog nyob rau hauv lub tsim ntawm monomer roj hmab extrusion tuag:
(1) Thaum twg cov roj hmab extruded los ntawm extrusion tuag, nws yuav nthuav txawv. Thaum lub hardness ntawm cov roj hmab nce los ntawm me me mus rau loj, tus nqi ntawm extrusion seem yuav txo los ntawm loj mus rau me me;
(2) Thaum lub extruder kub hloov ntawm qis mus rau siab, qhov extrusion seem expansion tus nqi hloov los ntawm me me mus rau loj;
(3) Thaum lub extrusion ceev hloov ntawm qis mus rau siab, cov khoom extrusion tsuas yog hloov los ntawm me me mus rau loj;
(4) Ntau hom roj hmab lossis roj hmab sib xyaw nrog cov roj hmab sib txawv muaj qhov sib txawv ntawm cov khoom siv extruded;
(5) Tus nqi nthuav dav ntawm txhua qhov hauv ntu ntawm cov khoom extrusion tsis xav kom dhau, tshwj xeeb tshaj yog rau ntu ntawm kev sib deev;
(6) Cov qauv tsim sib txawv ntawm extrusion tuag yuav muaj qhov sib txawv ntawm cov ntu thiab qhov loj ntawm cov khoom extrusion.
2) Cov teeb meem xav tau kev saib xyuas hauv kev tsim cov khoom siv roj hmab extrusion tuag
Ntxiv nrog rau cov yam ntxwv ntawm monomer roj hmab extrusion pwm tsim, kev tsim cov khoom sib xyaw roj hmab extrusion pwm kuj muaj cov cai tshwj xeeb hauv qab no.
(1) Nws yog ib qho tsim nyog los xyuas kom meej tias qhov sib txawv ntawm cov roj hmab sib txawv (thiab cov pob txha pob txha) yuav tsum ua tib zoo xyuas kom ntseeg tau tias cov roj hmab sib txawv (thiab cov pob txha) tuaj yeem ua ke zoo rau tag nrho;
(2) Rau qhov sib xyaw extrusion tuag nrog cov pob txha (hlau lossis hlau braid), nws yog ib qho tsim nyog los xyuas kom meej seb qhov kev sib txuas ntawm qhov sib txuas ntawm cov pob txha hlau lead-hauv tuag thiab cov extrusion tuag thiab kev xauv tsim ntawm kev kho qhov sib txawv. yog tsim nyog;
(3) Lub kaum sab xis ntawm cov pob txha txhuas-hauv tuag thiab cov kab noj hniav ntawm cov khoom sib xyaw extrusion tuag nyob rau hauv compound extrusion tuag yuav tsum tsim nyog.
