8. Nqus Moulding txheej txheem

(1) Qhov hnyav
Txiav txim siab tus nqi ntawm "C tivthaiv" raws li hardness koj xav tau thiab ntxiv rau A tivthaiv.
Ntsuas tus nqi tib yam los ntawm qhov hnyav ntawm B tivthaiv raws li A tivthaiv nyob rau hauv ib lub khob cais coj mus rau hauv tus account tus nqi uas yuav nyob twj ywm hauv lub khob.

(2) Pre-degassing
Ua ntej degassing hauv degassing chamber li 5 feeb.
Degass ntau npaum li koj xav tau.
Peb pom zoo kom degass tom qab cov khoom cua sov rau cov kua kub ntawm 25 ~ 35 ° C.

(3) Kub ntawm resin
Khaws cia txiasre of25 ~ 35 °C rau ob leeg A(muaj C tiv thaiv) thiab B tiv thaiv.
Thaum qhov kub ntawm cov khoom yog siab, lub lauj kaub lub neej ntawm kev sib tov yuav luv luv thiab thaum kub ntawm cov khoom yog tsawg, lub lauj kaub lub neej ntawm sib tov yuav ntev.

(4) Pwm kub
Khaws qhov kub ntawm silicone pwm pre-rhuab mus rau 60 ~ 700C.
Cov pwm kub qis dhau tuaj yeem ua rau kev kho tsis raug kom ua rau lub cev qis dua.Pwm qhov kub thiab txias yuav tsum tau tswj kom meej raws li lawv yuav cuam tshuam qhov tseeb qhov tseeb ntawm kab lus.

(5) Casting
Cov thawv ntim tau muab tso rau hauv ib txoj kev uasB tiv thaiv is ntxiv to A tiv thaiv (contais C tiv thaiv).
Siv lub tshuab nqus tsev rau lub chamber thiab de-gass A tivthaiv rau 5 ~ 10 feebthaum it is stirred los ntawm lub sij hawm mus rau lub sij hawm.
Ntxiv B tiv thaiv to A tiv thaiv(muaj C tiv thaiv)thiab do rau 30 ~ 40 vib nas this thiab tom qab ntawd nrum qhov sib tov nrawm rau hauv cov pwm silicone.
Tso lub tshuab nqus tsev hauv 1 thiab ib nrab ib feeb tom qab pib qhov sib tov.

(6) Kho mob
Muab cov pwm ntim rau hauv qhov cub thermostatic ntawm 60 ~ 700C rau 60 feeb rau Hom A hardness 90 thiab rau 120 feeb rau Hom A hardness 20 thiab demold.
Ua tom qab kho ntawm 600C rau 2 ~ 3 teev nyob ntawm qhov yuav tsum tau ua.

9. Flow daim ntawv ntawm lub tshuab nqus tsev casting

10. Ceev faj hauv kev tuav

(1) Raws li tag nrho A, B thiab C tivthaiv yog rhiab rau dej, tsis txhob cia dej nkag mus rau hauv cov khoom.Tsis tas li ntawd txwv tsis pub cov khoom los ntev kev sib cuag nrog dej.Kaw lub thawv kom nruj tom qab txhua qhov siv.

(2) Kev nkag mus rau hauv dej rau hauv A lossis C tivthaiv tuaj yeem ua rau muaj ntau cov pa npuas hauv cov khoom kho thiab yog tias qhov no yuav tsum tshwm sim, peb pom zoo kom sov A lossis C tivthaiv rau 80 ° C thiab degass hauv lub tshuab nqus tsev li 10 feeb.

(3) Ib feem yuav khov ntawm qhov kub qis dua 15 ° C.Kub rau 40 ~ 50 ° C thiab siv tom qab co nws zoo.

(4) B tivthaiv yuav hnov mob nrog noo noo los ua turbid lossis kho rau hauv cov khoom siv.Tsis txhob siv cov khoom siv thaum nws tau poob qhov pob tshab lossis nws tau pom tias muaj qhov tawv tawv vim cov ntaub ntawv no yuav ua rau lub cev qis dua.

(5) Lub sijhawm ntev cua sov ntawm B tivthaiv ntawm qhov kub siab tshaj 50 ° C yuav cuam tshuam rau qhov zoo ntawm B tivthaiv thiab cov kaus poom tuaj yeem nce siab los ntawm lub siab sab hauv.Khaws ntawm chav tsev kub.

11. Kev ceev faj txog kev nyab xeeb thiab kev nyiam huv

(1) B tivthaiv muaj ntau tshaj 1% ntawm 4,4'-Diphenylmethane diisocyanate.Txhim kho cov pa hauv zos hauv lub khw ua haujlwm kom ruaj ntseg zoo ntawm cov pa.

(2) Saib xyuas kom txhais tes lossis tawv nqaij tsis tuaj yeem sib cuag nrog cov khoom siv raw.Thaum muaj kev sib cuag, ntxuav nrog xab npum thiab dej tam sim ntawd.Nws yuav ua rau khaus tes lossis tawv nqaij yog tias lawv sab laug nrog cov ntaub ntawv raw rau lub sijhawm ntev.

(3) Yog tias cov khoom nyoos nkag rau hauv qhov muag, yaug nrog dej ntws rau 15 feeb thiab hu rau kws kho mob.

(4) Txhim kho cov kav dej rau lub tshuab nqus tsev kom ntseeg tau tias cov pa tawm mus rau sab nraud ntawm lub khw ua haujlwm.
