(37) Glassfiber kwj Txhaj Moulding Txheej Txheem Kev Tswj Xyuas Kev Tswj Xyuas Tsis Zoo (65 hom)

Qhov saum npoo ntawm cov khoom yas molded nrog iav fiber ntau ntxiv rau ntawm qhov chaw nthuav tawm ntau yam tsis xws luag: grey, ntxhib, thiab qee qhov pom tseeb xws li cov xim hlau ci, tshwj xeeb tshaj yog nyob rau hauv qhov convex ntawm cov khoom ntws hauv cheeb tsam, ze ntawm cov kab sib txuas uas cov dej sib ntsib. dua.
Lub cev ua rau
Yog tias qhov ntsuas kub qis dhau lawm thiab cov pwm kub qis dhau lawm, cov ntaub ntawv uas muaj cov iav fiber ntau yuav ua kom nrawm nrawm rau ntawm pwm nto, thiab tom qab ntawd cov iav fibers yuav tsis muab tso rau hauv cov yaj. Thaum ob txoj hlua ntawm cov khoom ntws sib ntsib, kev taw qhia ntawm cov iav fibers yog nyob rau hauv cov kev taw qhia ntawm txhua strand, uas ua rau irregularities nyob rau hauv cov ntaub ntawv saum npoo ntawm qhov kev sib tshuam, uas ua rau cov kev sib txuas ntawm seams los yog cov ntaub ntawv khiav kab.
Cov phenomena no tshwm sim ntau dua thaum cov khoom molten nyob rau hauv cov khoom chim yog tsis sib tov kiag li, xws li thaum lub ntsia hlau stroke ntev dhau lawm, ua rau tsis sib xws ntawm cov khoom molten thiab txhaj tshuaj ntawm cov khoom molten.
Cov laj thawj thiab kev txhim kho kev ntsuas cuam tshuam txog kev ua tsis tau muaj nyob hauv cov lus hauv qab no:
1. Kev txhaj tshuaj ceev tsawg dhau Kev txhaj tshuaj nrawm: xav txog kev txhaj tshuaj ntau theem: qeeb ua ntej - nrawm tom qab
2. Pwm tsawg heev ua rau pwm kub
3. Yog hais tias qhov kub ntawm melting tsawg dhau lawm, nws yuav ua rau kom lub chim kub thiab ua rau cov ntsia hlau rov qab siab
4. Kev hloov pauv siab hauv qhov kub thiab txias, xws li qhov tsis sib xws ntawm melting nce ntsia hlau rov qab siab; Txo cov ntsia hlau ceev; Siv lub thoob ntev dua los ua kom luv luv
