ABS Extruded Profiles
1. ABS muaj ntau dua hygroscopicity thiab av noo rhiab heev. Ua ntej moulding, nws yuav tsum tau ua kom qhuav thiab preheated (tsawg kawg 2 teev ntawm 80 ~ 90 ° C) txhawm rau tswj cov ntsiab lus noo noo hauv qab 0.03%.
2. Cov yaj yaj viscosity ntawm ABS resin yog qhov tsis raug rau qhov kub thiab txias (sib txawv ntawm lwm cov amorphous resins).
Nws tuaj yeem nce fluidity los ntawm nce ntsia hlau ceev lossis txhaj tshuaj siab. Qhov ntsuas kub tag nrho yog nyiam dua 190-235 ° C.
3. Qhov yaj yaj viscosity ntawm ABS yog qhov nruab nrab, siab dua li ntawm PS, HIPS, thiab AS yog siab dua, thiab npias nrog txhaj tshuaj dua (500 ~ 1000bar) yog qhov yuav tsum tau ua.
4. Hauv kev siv ntawm ABS Extruded Profiles, qhov siab tshaj tawm npias txhaj tshuaj nrawm nrawm nrawm dua thiab cov nyhuv tau zoo dua. (Tshwj tsis yog tias cov duab yog qhov nyuaj thiab qhov sib txawv-phab ntsa qhov yuav tsum tau txhaj tshuaj ntau dua), cov dej qib ntawm cov khoom lag luam yog cuam tshuam rau cov pa ib puag ncig.
5. Kev ntsuas kub ntawm molding ntawm ABS Extruded Profiles yog tus nqi siab, thiab cov pwm kub feem ntau kho ntawm 25-70 ° C. Thaum ua cov khoom lag luam loj, qhov kub ntawm cov pwm ruaj khov (pwm nyob rau sab pem hauv ntej) feem ntau siab dua qhov ntsuas kub ntawm cov pwm txav (sab pwm tom ntej) los txog 5 ° C. (Cov pwm kub yuav cuam tshuam qhov ua tiav ntawm qhov chaw yas, thiab qhov kub qis dua yuav cuam tshuam qhov ua tiav thiab txo qhov ua tiav).
