Txog kev ntsuas dej ntawm cov yas resin

Cov dej noo ntawm cov khoom yas zoo heev cuam tshuam rau qhov zoo ntawm kev txhaj tshuaj molded khoom. Txawm hais tias nws yog cov dej noo hauv cov khoom yas los yog cov dej noo uas txuas rau saum npoo ntawm cov khoom, nws yuav ua rau muaj teeb meem zoo hauv kev tsim khoom yas.

Ntxiv mus, feem ntau cov yas yuav nqus dej noo los ntawm huab cua mus rau ib qho twg, thiab cov dej noo absorbed los ntawm cov yas feem ntau muaj feem xyuam rau hom resin.

Kev nqus dej ntawm cov yas yuav muaj qhov cuam tshuam tsis zoo rau cov txheej txheem molding, uas tuaj yeem ua rau muaj teeb meem yooj yim xws li ntxhib nto, npuas lossis cov khoom siv tsis zoo ntawm cov khoom ua tiav.

Nws yog ib qho nyuaj los xyuas seb puas muaj cov dej noo hauv cov khoom yas los ntawm kev soj ntsuam qhov muag liab qab. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau siv cov cuab yeej ntsuas sib txuas lossis cov cuab yeej siv los ntsuas cov dej noo ntawm cov yas los txhim kho cov teeb meem tshwm sim los ntawm cov dej noo ntau dhau thaum lub sij hawm molding txheej txheem.

Lub hom phiaj ntawm kev kuaj cov yas ya raws

Nyob rau hauv cov txheej txheem ntawm engineering yas molding, nws yog ib qho tseem ceeb heev los tswj cov dej noo ntawm cov ntaub ntawv yas granule raw khoom. Cov dej noo ntau dhau ntawm cov yas granules tuaj yeem yooj yim ua npuas rau ntawm qhov chaw lossis sab hauv ntawm cov khoom molded, los yog cov teeb meem xws li cov khoom siv tsis zoo, cov tshuaj tsuag, thiab cov xov tooj ntawm cov nyiaj.

Cov dej noo ntawm PP yas granules yuav tsum tau tswj hauv qab no {{0}}.2 lossis 0.4%, thaum cov dej noo ntawm ABS yas granules yuav tsum tswj qis dua 0.1%.

Lub hom phiaj ntawm kev siv lub tshuab ziab khaub ncaws los txiav txim siab cov dej noo ntawm PP granules thiab ABS granules yog los txiav txim siab los ntawm kev ntsuas ntsuas tias cov dej noo ntawm engineering yas raw cov ntaub ntawv ua tau raws li qhov ntsuas qhov ntsuas ntawm: PP granules noo noo tsawg dua lossis sib npaug. {{0}}.2% lossis 0.4%, ABS yas ya raws tsawg dua lossis sib npaug li 0.1%.

Yog tias cov dej noo ntau tshaj tus qauv, kev kho kom qhuav yog ua ntej txhaj tshuaj molding thiab molding.

Yog tias cov ntsiab lus noo noo ua tau raws li qhov tshwj xeeb, nws tsis tas yuav tsum tau ziab kom tsis txhob qhuav qhov muag tsis pom kev, ua kom lub zog noj, thiab ua rau poob.

Txoj cai ntawm kev ntsuas dej noo rau cov khoom yas

Cov dej noo ntawm cov khoom yas yog kuaj los ntawm kev tso cov khoom yas ntawm qhov ntsuas kub, ziab lawv, thiab suav cov feem pua ​​​​ntawm cov khoom sib txawv ua ntej thiab tom qab cua sov thiab qhov loj ntawm cov khoom yas ua ntej cua sov, uas yog, cov ntsiab lus noo noo.

Yas ya raws kuaj sim

1) Cov kev xav tau rau kev npaj ntawm ABS yas particle qauv
ABS yas hais muaj peev xwm nqus dej muaj zog, thiab lawv qhov nqus dej feem ntau tuaj yeem ncav cuag {{0}}.25% rau 0.45%. Nws tuaj yeem pom tau tias tom qab ziab thiab muab tso rau hauv huab cua rau ib lub sijhawm, lawv yuav nqus dej thiab ua kom ntub dej, thiab cov ntsiab lus noo noo yuav ntau dua 0.4%. Yog li ntawd, ua ntej tus neeg siv khoom xav tau cov khoom siv ABS yuav tsum tau muab tso rau hauv qhov cub kom qhuav, qhuav ntawm 82 degree rau 2 teev, txias, thiab kuaj cov dej noo.
2) ABS yas particle xeem hom, cua sov kub thiab sampling ntim
Ua ntej pib qhov kev xeem, ua ntej tsim ib lub tsev qiv ntawv qauv, nkag mus rau tus qauv lub npe: ABS hais, xaiv hom kev ntsuas tsis siv neeg, teeb lub cua sov rau tus qauv, thiab nkag mus rau qhov ntsuas kub hauv kem qhov kub thiab txias.
3) ABS yas particle xeem txheej txheem

Muab li 20g ntawm ABS cov khoom yas rau hauv cov qauv phaj, npog cov cua sov chamber npog, xaiv lub pob pib, thiab thaum kawg ntawm qhov kev xeem, qhov ntsuas yuav cia li kaw thiab tso saib cov ntsiab lus noo noo ntawm cov qauv. Rov ua qhov kev sim 3 zaug thiab sau cov ntaub ntawv.

4) Kev suav cov ntaub ntawv

Qhov nruab nrab noo noo ntawm ABS yas particle W{{0}}}(005%+0.03%+0.06%)/ 3≈0.047%, uas ua tau raws li qhov yuav tsum tau muaj cov dej noo ntawm ABS cov khoom yas tsawg dua lossis sib npaug li 0.1%.

5) PP yas particle qauv kev npaj yuav tsum

PP cov khoom yas muaj peev xwm nqus dej tsis muaj zog, thiab lawv cov dej nqus dej tsawg dua 0.03%. Nws tuaj yeem pom tias tom qab ziab thiab muab tso rau hauv huab cua rau ib lub sijhawm, lawv yuav tsis nqus dej thiab noo noo, thiab cov ntsiab lus noo noo yuav tsis cuam tshuam. Yog li ntawd, cov qauv tuaj yeem raug kuaj ncaj qha.

6) PP yas particle xeem hom, cua sov kub thiab sampling ntim
Ua ntej pib qhov kev ntsuam xyuas, ua ntej tsim ib lub tsev qiv ntawv qauv, nkag mus rau tus qauv lub npe: PP hais, xaiv hom kev ntsuas raws li qhov tsis siv neeg, teeb lub cua sov rau tus qauv, thiab nkag mus rau qhov ntsuas kub hauv kab ntawv kub.

7) PP yas particle xeem txheej txheem

Noj li ntawm 20g ntawm PP cov khoom yas thiab muab tso rau hauv cov qauv phaj, npog cov cua sov chamber npog, xaiv lub pob pib, thiab thaum kawg ntawm qhov kev ntsuam xyuas, qhov ntsuas yuav cia li kaw thiab tso saib cov dej noo ntawm cov qauv. Rov ua qhov kev sim 3 zaug thiab sau cov ntaub ntawv.

Yog tias koj xav tau lub tshuab nqus dej yas, thov saib cov ntaub ntawv ntsuas thiab tiv tauj peb:
