Hom yas rau lub tshuab nqus tsev ua qauv: Qhov kawg cov khoom qhia

Lub tshuab nqus tsev (tseem hu ua thermoforming) yog ib qho kev tsim khoom, nws yuav tsum tau ua haujlwm ntawm cov pwm thiab kev tshaj tawm cov khoom siv cov khoom siv ua khoom noj, nws ib zaug los ntawm cov pwm ua kom txias, nws tau hais txog cov khoom siv roj hmab yas, nws muaj dab tsi los ntawm cov pwm ua kom txias, nws tau hais txog kev kho cov pwm thiab kev tshaj tawm cov khoom siv rau kev kho mob, nws muaj dab tsi los ntawm cov pwm ua kom txias thiab kev tshaj tawm cov khoom siv rau kev kho mob, nws muaj dab tsi los ntawm cov pwm ua kom txias, nws tau hais txog cov khoom siv roj hmab yas, nws muaj dab tsi los ntawm cov pwm ua kom huv thiab kev tshaj tawm cov khoom lag luam rau kev kho mobtsis yog txhua tus coj tus cwj pwm zoo ib yam hauv qab cua sov thiab nqus plua plav. Xaiv cov khoom siv uas koj muaj qhov tsis meej, kev pom tseeb, nqi, thiab txawm tias nws ib puag ncig.

1. Dab tsi yog cov nqus tsev ua tiav?

Ua ntej poob siab rau plastics, nws muaj txiaj ntsig kom nkag siab cov txheej txheem lawv tau siv hauv:

Ib daim ntawv yas yog clamped thiab rhuab kom txog thaum muaj pliable (feem ntau 115-165 degree) {2}.

Daim ntawv muag muag muag yog draped dhau los yog mus rau hauv pwm .

Lub tshuab nqus tsev (≈9 .} 8-12.25 psi) rub daim ntawv kaw kom nruj tawm tsam cov pwm sib nraus.

Tom qab txias, feem ntau yog txiav thiab ua tiav .

Cov txheej txheem qis-siab favors cov ntaub ntawv uasncab tusyees yam tsis muaj thinning ntau dhau, ua raws li cov pwm kom haum, thiab txias yam tsis muaj kev sib tsoo lossis tawg} Tam sim no, cia peb tshawb nrhiav tias plastics xa tawm .
