Yuav ua li cas elastomers tsim?
Cov txheej txheem tsim khoom elastomer suav nrog kev sib txuas cov khoom xyaw raw ntawm elastomer thiab ua rau ntau txoj hauv kev kom ua tiav cov polymer kawg. Ib kauj ruam dhau los, qhov no yog li cas elastomers raug tsim:
Sib tov
Lub hauv paus polymer tuaj yeem ua ke nrog lwm cov khoom xyaw los tsim cov ntaub ntawv muaj zog thiab tiv taus ntau dua los ntawm kev sib xyaw:
Ua ntej, cov polymer yog muab tso rau hauv ib qho qhib sib tov zeb.
Yog li cov batch tsis kub dhau, dej txias yog siv nyob rau hauv lub tshuab chais.
Cov txheej txheem pabcuam tuaj yeem raug ntxiv thaum ntxov kom tshem tawm qhov muaj peev xwm ua raws.
Ob peb hauv-txiav yog ua thoob plaws hauv cov txheej txheem kom ntseeg tau tias cov khoom xyaw sib npaug.
Thaum tag nrho cov khoom xyaw ntxiv tau ua ke, cov batch raug rho tawm thiab ua tiav los ntawm lub zeb dua ntawm qhov chaw nruj tshaj plaws kom ntseeg tau tias cov khoom sib xyaw yog homogenous thiab zoo-dispersed.
Qhov sib tov yog thaum kawg sheeted tawm kom txias.
Kev npaj
Ua ntej moulded, elastomers feem ntau yog hloov pauv kom cov txheej txheem molding tsis muaj qhov tsis zoo. Ua ntej, elastomer raug yuam los ntawm kev tuag los tsim nws rau hauv qhov tsim nyog qhov ntev, hu ua preform extrusion. Qhov no tuaj yeem ua raws li ntau txoj hauv kev ntawm kev npaj, xws li blanking. Ntawm Linde Polymer blanks tuaj yeem txiav los ntawm tes rau cov khoom siv tshwj xeeb lossis tuaj yeem txiav los ntawm lub tshuab. Rau cov kev siv tshwj xeeb, cov cuab yeej preform tuaj yeem siv los yog cov roj hmab tuaj yeem raug punched kom loj.
Tom qab lub elastomer dhau mus rau theem npaj, lub elastomer tuaj yeem raug molded.
Moulding
Muaj peb txoj hauv kev uas elastomers tuaj yeem raug molded kom tiav rau hauv cov khoom kawg. Txhua txoj kev nthuav tawm cov txiaj ntsig sib txawv thiab raug xaiv raws li qhov khoom kawg xav tau rau. Cov hom molding rau elastomers muaj xws li:
Compression
Compression molding yog ib txoj kev zoo heev ntawm molding. Nws yog ua tiav los ntawm thawj muab cov khoom siv tsis tau kho elastomer rau hauv lub pwm preheated. Los ntawm kev siab, lub elastomer tom qab ntawd ua raws li cov qauv ntawm cov pwm. Txoj kev no yog tsim rau tej yam yooj yim thiab kuj complex ib yam. Compression molding muaj qhov zoo ntawm cov cuab yeej siv qis thiab cov kev cai ua haujlwm tsawg. Vim tias cov cuab yeej muaj lub sijhawm teem sijhawm luv luv Linde Polymer tuaj yeem hloov cov pwm compression ntau zaus hauv kev ua haujlwm, ua kev txiav txim qis dua 10 O-rings yooj yim thiab siv tau.
Hloov
Hloov molding yog ib txoj kev zoo sib xws rau compression molding. Lub elastomer muab tso rau hauv lub lauj kaub, thaum lub cuab yeej kaw cov roj hmab yog thawb los ntawm cov rooj vag thiab hloov qhov mus rau hauv cov kab noj hniav. Hloov molding feem ntau yog siv rau cov roj hmab rau substrate bonded Cheebtsam los yog pwm uas muaj ntau kab noj hniav. Whilst nyob rau hauv tej rooj plaub nws muaj peev xwm muab qhov zoo dua ntawm ntau lawm nws yog feem ntau yog ib qho kev xaiv kim tshaj li compression molding. Rau qee yam khoom, cov lus pov thawj kuj tuaj yeem tsim tawm uas tej zaum yuav tsis xav tau hauv cov ntawv thov dynamic lossis tuaj yeem muab cov ntsiab lus pib rau kev tsim kua muag.
Txhaj tshuaj
Kev txhaj tshuaj molding yog ib txoj hauv kev zoo tshaj plaws ntawm molding vim nws cov precision thiab ceev. Lub elastomer yog thawj rhuab nyob rau hauv lub prewarming chamber. Tom qab ntawd lub elastomer raug yuam mus rau hauv pwm los ntawm cov ntsia hlau los yog piston ntawm tus nqi siab shear rau hauv pwm kom zoo li tus yam xav tau. Whilst txhaj pwm yog cov khoom tsim tau zoo, lawv kim heev thiab tuaj yeem siv cov txheej txheem nyuaj ntawm cov neeg khiav dej num. Rau cov ntaub ntawv tseem ceeb xws li FKM thiab FFKM, cov khoom seem tsim los ntawm cov neeg khiav dej num tuaj yeem ua rau cov txheej txheem no tsis muaj kev sib tw. Tsis zoo li cov yas txhaj tshuaj molding, cov neeg khiav dej num tsis tuaj yeem tsuas yog rov ua dua rov qab rau hauv cov khoom.
