12 cov ntsiab lus kom nco ntsoov lub hau ntsaws ntawm txhaj tshuaj molding tshuab
Jun 28, 2019
1. Txav cov khoom siv nrog lub hau ntswj. Tshwj xeeb yog rau cov khoom siv corrosive thiab cov ntaub ntawv nyuab, xws li PVC, hluav taws kub nyhiab, cov ntaub ntawv iav fiber ntau ntxiv yuav tsum siv kev screws, zam tsis zoo tib yam.
2. Yog tias cov khoom siv cav tsis zoo siv, yuav tsum siv cov khoom ruaj khov xws li HDPE, HIPS, thiab lwm yam rau thawj zaug tom qab siv.
3. Yog tias cov tshuab qub siv qee zaus siv iav fiber ntau, nco ntsoov siv cov khoom siv kub siab, qis qis qis, qis qis siab, nco ntsoov nco.
4. Thaum siv tshuaj molding tshuab pib, nws yuav tsum muab siab ua ntej los ntawm txhaj tshuaj molding. Tom qab lub fwj nce mus txog kev kub ntxhov, qhov ntsuas kub cia rau hauv qab Φ 60mm rau 15 feeb. Tom qab qhov saum toj no 30 feeb, lub tshuab pib dua rov qab pib qhov kev txiav txim plaub hau.
5. Txawm tsis muaj cov khoom, sim tsis txhob siv qhov txo qis dua. Piv txwv, cov khoom siv PC yuav ua tau tawm ntawm 250 degrees. ABS kuj tseem siv tau thaum 185 degrees, tab sis nws tsis zoo rau lub hau ntswj vim nws yuav tsum tau loj torque thiab loj hnav. Nyob rau tib lub sijhawm, yog siv qhov qis qis, qhov qis qis siv tsawg.
6. Txhua zaus lub cav nres rau ntau tshaj li ib nrab teev, nws yog qhov zoo tshaj rau qhov kaw qhov chaw txav thaiv thiab ntxuav cov khoom ntawm lub fwj los tsim kom muaj qhov txuag cov txuag.
7. Txhob siv tej khoom txawv teb chaws poob mus rau hauv lub thoob thiab ua rau lub hau ntswj thiab lub phom. Tiv thaiv hlau tawg thiab khib nyiab los ntawm kev poob rau hauv qhov taub. Yog hais tias cov khoom ua tiav, ib qho ntxiv ntawm cov hlau nplaum yog ntxiv los tiv thaiv cov hlau chips tsis txhob nkag rau hauv lub hwj.
8. Thaum siv cov tshuaj tiv thaiv, nco ntsoov tias cov yas hauv lub thoob mas yaj yuav tag nrho kom tsis txhob muaj kev puas tsuaj rau lub hauv nruab nrab ntawm cov tsav tsheb thaum lub hau tawm rov qab.
9. Tsis txhob muaj qhov tshwm sim ntawm txoj kev vau idling thiab slipping.
10. Thaum siv cov yas tshiab, cov khoom seem ntawm lub thoob yuav tsum tau muab ntxuav. Thaum siv POM, PVC, PA + GF thiab lwm yam ntaub ntawv, sim txo qhov degradation ntawm cov ntaub ntawv raw. Tom qab shutdown, yaug nrog ABS thiab lwm cov ntaub ntawv cov tshuab.
11. Tsis txhob sib tov POM thiab PVC mus rau hauv lub thoob rau tib lub sijhawm, thiab hnov mob thaum lub ntsuas kub kom ua rau raug mob loj heev.
12. Thaum qhov kub ntawm cov hlau yas yog li qub tiam sis nws pom tau tias cov hlau yas tau dub me ntsis los yog muaj suab thaj, xyuas seb cov roj hmab rub rov qab ntiv nplhaib lub rooj (dhau ntawm qhov hnyuv, qhov chaw) puas ntsoog.
