LSR kua silicone ua pwm daim ntawv thov

Cov kua roj kua nyeem ua kua silica yog sau ua LSR, uas yog cov khoom lag luam uas tuaj yeem nyiam los ntawm cov neeg siv khoom thiab cov tsim khoom. Cov kua nplaum ua kua silica yog tsim cov tshuaj pleev xim silica. Nws muaj zoo elasticity, waterproof thiab noo noo tsis kam, thiab yog tiv taus acid, alkali thiab lwm yam tshuaj lom neeg. Feem ntau siv los hloov cov khoom yas txhua hnub.

Silicone kua roj hmab txhaj tshuaj molding tshuab (LIM) yog cov tshiab thiab txuag silicone roj hmab molding kev tsim qauv thaum kawg xyoo 1970. Nws ua ke kev ua tau zoo tshaj plaws kua roj hmab silicone nrog cov khoom siv uas tuaj yeem hais kom raug thiab khov kho kom tiav kev txhaj tshuaj molding. Cov txheej txheem tsim hom tshiab ntawm silicone roj hmab molding thiab kev siv tshuab yuav tsum tau tsuas yog ob feem (uas tseem tuaj yeem suav cov khoom siv ntu xws li xim sib txuam) rau hauv cov khoom siv, thiab cov txheej txheem los ntawm kev pub mis, metering, kev sib xyaw rau moulding yog tag nrho cov tshuab. Lub tshuab ua haujlwm no tuaj yeem ua tiav lub hom phiaj ntawm cov txheej txheem yooj yim, lub sijhawm ua tiav cov sijhawm tsawg, txuag khoom, thiab txhim kho kev ua tau zoo. Thiab tsis muaj lub hauv paus tsis muaj pov tseg pov tseg hauv cov txheej txheem ntau lawm, uas tau txais txiaj ntsig ib puag ncig kev tiv thaiv.

 

 

 

Cov tshuab txhaj tshuaj tag nrho yog muab faib rau cov ntu hauv qab no:

Thawj chav yog chav ntsuas khoom noj thiab ntsuas khoom noj, uas ntsuas qhov tseeb ntawm ob qho kev sib xyaw ntawm cov kua roj silicone roj ncaj qha los ntawm lub thawv ntim rau hauv qhov system los ntawm hydraulic siab phaj;

Chav ob yog chav sib xyaw. Ob qhov sib xyaw ua ke nkag mus rau hauv lub kaw lus tau siab sib xyaw ua ke los ntawm kev sib tov zoo li qub, thiab tsis muaj kab npuas tuaj rau hauv qhov system;

Qhov thib peb yog chav txhaj tshuaj txhaj molding. Cov khoom siv roj hmab silicone sib xyaw ua ke yog qhov sib xyaw ntawm qhov txhaj tshuaj, thiab tusyees faib rau txhua qhov kab noj hniav, thiab tom qab ntawd thermally vulcanized. Tag nrho cov txheej txheem yog tag nrho cov tshuab, thiab tsis muaj kev tuav tswj tau pom tau tom qab teeb tsa cov tsis dhau los txhim kho kev ua haujlwm ntau lawm.

 

Cov kev txwv qee yam ntawm LSR kev ua hauj lwm zoo

LSR muaj ntau qhov zoo, nws yuav tsum muaj lub zeem muag dav dav hauv khw. Tab sis raws li qhov tam sim no cov tshuab kev lag luam yog kev txhawj xeeb, LSR tsis yog tus phooj ywg zoo, uas tau muab tso ua ke hauv kev txwv ntawm kev tsim khoom. Hais txog qhov kev tsim khoom ntau lawm, koj tuaj yeem xa mus rau hauv daim duab hauv qab no. Cov khoom tivthaiv muaj cov catalyst thiab cov B tivthaiv tus B muaj tus sawv cev sib txuas. Tom qab sib tov los ntawm 1: 1, nws tau txhaj rau hauv cov pwm los ntawm cov ntsia hlau tshwj xeeb thiab vulcanized mus rau hauv elastomer thaum kub, thiab tom qab ntawd kho cov kab mob hauv pwm. txoj kev ua.

 

Cov teeb meem tseem ceeb tau tam sim no suav nrog:

1. Kev kho qhov ceev ntawm cov khoom siv nws tus kheej yog 5-8S / hli, uas txwv qhov kev txhaj tshuaj molding kev ua haujlwm ntawm tus nrawm nrawm dua.

2. Cov kua silicone muaj qhov ntau fluidity ua ntej kho, thiab nws yog qhov yooj yim los tsim flash thaum lub sijhawm txhaj tshuaj, uas yuav tsum muaj qhov siab xav tau ntawm kev ua haujlwm ntawm cov pwm thiab raug qhov tseeb ntawm lub tshuab txhaj tshuaj.

3. Cov kua roj ua kua silicone yog cov muag muag, thiab cov khoom lag luam yuav nthuav dav hauv qhov txheej txheem thaum lub sijhawm ua cov txheej txheem, thiab ntsws hauv ntim tom qab txias, uas ua rau muaj teeb meem loj hauv cov khoom lag luam thaum lub tshuab ua lag luam.
