Amorphous Txhaj Moulding Tshuab

Cov tshuab txhaj tshuaj molding feem ntau yog muab faib ua cov tshuab rau cov khoom siv crystalline thiab amorphous plastics. Ntawm lawv, amorphous yas txhaj tshuaj molding tshuab yog cov tshuab tsim thiab ua kom zoo rau kev ua cov ntaub ntawv amorphous (xws li PC, PMMA, PSU, ABS, PS, PVC, thiab lwm yam).

Nta ntawm amorphous txhaj tshuaj molding tshuab

Kub tswj qhov system:

Nruab nrog kev tswj qhov kub thiab txias kom ntseeg tau tias nws tuaj yeem tswj tau qhov kub thiab txias kom tsis txhob muaj cov khoom overheating thiab decomposition.
Kev tswj qhov kub ntawm segmented feem ntau yog xav tau.

1. Screw tsim:

Cov ntsia hlau yuav tsum muab cov shear kom raug thiab kev sib xyaw ua haujlwm rau cov khoom siv amorphous, feem ntau nrog cov compression qis thiab cov qauv tsim tshwj xeeb kom haum rau cov khoom siv.

2. Txhaj ceev thiab siab:

Kev txhaj tshuaj ntau dua thiab kev txhaj tshuaj qeeb qeeb yuav tsum tau zam kom tsis txhob muaj cua npuas thiab ua kom lub ntsej muag du.

3. Pwm cua sov thiab cua txias:

Kev tswj qhov kub thiab txias ntawm cov pwm yog yuav tsum tau, thiab pwm thermostat feem ntau yog siv los tswj qhov kub thiab txias.

4. Cua venting thiab degassing:

Amorphous plastics yog qhov ua rau cov pa roj npuas lossis cov pa roj decomposition, yog li cov tshuab molding thiab pwm xav tau kev ua haujlwm zoo.

Cov khoom ntawm Amorphous Plastics

• Tsis tas li melting point: softens maj mam thaum rhuab, es melting sai sai ntawm ib tug tej yam kub zoo li crystalline plastics.
• Kev hloov pauv ntawm iav siab (Tg): Kub siab dua yuav tsum tau ua kom tiav cov yas ntws.
• qis shrinkage: Ua tiav amorphous plastics yog qhov tseeb dua thiab muaj kev sib tw tsawg dua thiab kev sib txawv.
• Zoo pob tshab:Qee cov ntaub ntawv amorphous, xws li PC thiab PMMA, muaj cov khoom siv kho qhov muag zoo heev.
• Txwv tshuaj tsis kam:cov kev cai tshwj xeeb rau cov khoom siv thiab pwm.
