PP daim ntawv pob tshab siab extrusion kab

PP pob tshab siab daim ntawv extrusion kab Feem ntau yog siv los tsim cov ntawv polypropylene (PP) pob tshab siab. Vim nws qhov pob tshab zoo, tiv taus tshuaj lom neeg, tawv thiab rov ua dua tshiab, nws yog dav siv hauv kev ntim khoom noj, ntim khoom siv kho mob, kev tiv thaiv khoom siv hluav taws xob, cov khoom luam ntawv thiab lwm yam teb.

Cov hauv qab no yog cov ntsiab lus ntawm cov khoom tseem ceeb thiab cov txheej txheem ua haujlwm ntawm cov kab ntau lawm:

Raw khoom npaj

Ua ntej, siv cov khoom siv PP qhuav ua cov khoom siv raw. Cov khoom siv raw no yuav tsum tau ua kom qhuav kom tshem tawm cov dej noo thiab zam cov npuas thaum lub sijhawm ua tiav, uas yuav cuam tshuam rau qhov pob tshab thiab zoo ntawm daim ntawv.

Extruder

Cov ntaub ntawv sib xyaw ua ke raug pub rau hauv ib lub tshuab extruder ib leeg lossis ob lub tshuab extruder los ntawm lub kaw lus pub mis. tshuab riam yaj cov khoom siv granular rau hauv ib qho sib xws yaj los ntawm kev cua sov thiab qhov seem shearing, seem plasticizing, thiab seem conveying ntawm lub hau ntswj.

Pom lawv

Yuav kom ntseeg tau tias daim ntawv pob tshab thiab huv si, cov yaj yuav dhau los ntawm lub lim dej precision tom qab extrusion kom tshem tawm cov khoom tsis huv, xws li cov khoom tsis yaj lossis cov khoom txawv teb chaws.

Metering twj tso kua mis

Cov yaj uas lim lawm yuav nkag mus rau hauv lub twj ntsuas. Los ntawm kev tswj qhov nrawm ntawm cov yaj thiab ua haujlwm nrog lub tshuab tseem ceeb, cov khoom yaj tuaj yeem xa mus rau lub pwm ua ntawv kom zoo thiab ruaj khov, ua lub luag haujlwm tseem ceeb hauv kev kho qhov tuab ntawm daim ntawv.

Pwm thiab tuag

Tom qab cov khoom siv PP uas yaj tawm hauv lub extruder, nws dhau los ntawm cov pwm thiab pwm tsim tshwj xeeb los ua daim ntawv nrog qhov tuab thiab qhov tiaj tiaj uas xav tau, thiab tswj qhov dav ntawm cov khoom. Rau cov ntawv pob tshab siab, kev tsim cov pwm thiab pwm yog qhov tseem ceeb heev, xyuas kom meej tias cov khoom ntws sib npaug thiab tsis muaj npuas tsim kom ua tiav cov kev xav tau pob tshab siab.

Lub kaw lus txias thiab ua kom zoo nkauj

Cov ntawv kub yaj uas tawm ntawm lub taub hau tuag hla dhau lub pwm lossis lub pwm thiab tam sim ntawd nkag mus rau hauv lub calender kom txias sai thiab ua kom zoo nkauj los kho qhov tuab thiab dav ntawm daim ntawv extrusion. Lub calender tswj lub qhov kub ntawm lub roller kom txias cov dej los ntawm lub pej thuam dej (lossis chiller). Vim tias PP muaj qhov shrinkage loj heev, nws yuav tsum tau txias tag ua ntej winding kom tshem tawm kev ntxhov siab sab hauv, yog li cov khoom tuaj yeem ncav cuag tus qauv thiab yuav tsis shrink tom qab raug tso tseg rau ib lub sijhawm tom qab winding.

Lub cuab yeej traction thiab trimming

Tom qab txias thiab ua kom zoo nkauj, daim ntawv hla dhau lub cuab yeej txiav thiab raug txiav raws li qhov loj me xav tau. Qhov dav xav tau ntawm daim ntawv raug kho thiab cov npoo tsis tsim nyog ntawm ob sab raug txiav tawm. Lub cuab yeej rub thiab lub calender raug txuas ua ke, uas tuaj yeem tswj tau qhov tsim tawm ntawm daim ntawv, tswj nws qhov ceev thiab kev nruj, thiab tswj qhov tiaj tus thiab tuab ntawm daim ntawv.

Winding qhov system

Thaum kawg, cov ntawv txiav raug qhwv rau ntawm lub reel. Lub reel yog tswj los ntawm lub cev muaj zog servo nrog kev nruj tas li, uas tuaj yeem ua kom cov npoo ntawm cov kauj zoo nkauj. Lub zog ntswj ntawm cov kauj sab hauv thiab sab nraud yog tib yam, yog li cov kauj yuav tsis nruj sab hauv thiab xoob sab nraud, uas yooj yim rau kev ntim khoom tom qab, khaws cia thiab thauj mus los.

Yog tias koj xav ua kev txiav, tais, luam ntawv thiab ntim khoom, koj yuav tsum ntxiv lub tshuab txiav rau tom qab kawg. Hauv cov txheej txheem ntau lawm, koj kuj yuav tsum ntxiv lub cuab yeej laminating los laminar sab saud thiab sab qis ntawm daim ntawv ua ntej txiav (zaj duab xis tuaj yeem raug rhuav tshem los ntawm tes) los tiv thaiv daim ntawv thaum lub sijhawm thauj mus los yam tsis ua rau puas tsuaj rau saum npoo ntawm daim ntawv.

Thoob plaws hauv cov txheej txheem ntau lawm, kev tswj qhov kub thiab txias, qhov sib piv ntawm cov khoom siv, kev ua kom txias thiab kev ua haujlwm raug yog cov yam tseem ceeb uas cuam tshuam rau qhov zoo ntawm Cov ntawv PP pob tshab siabNtxiv rau, kom ua tau raws li cov kev cai thov sib txawv, cov kab ntau lawm kuj tseem yuav raug koom ua ke nrog lub kaw lus pub mis ntxiv kom ntxiv cov neeg sawv cev antistatic, cov roj nplua nyeem lossis lwm yam kev hloov kho kom txhim kho kev ua tau zoo ntawm daim ntawv.
