Hauv ob xyoos dhau los, nrog kev nce qib ntawm cov iav fwj hauv kev ua lag luam, ntau thiab ntau tus neeg yuav xaiv iav fwj thaum xaiv cov khoom ntim. Thaum tib neeg xaiv cov iav fwj, lawv kuj muaj ntau thiab ntau qhov kev xav tau zoo. siab dua. Qee zaum peb yuav pom tias cov iav fwj uas tsim tawm yuav muaj qee qhov ua tsis tiav tom qab tsim. Qhov no yog vim li cas?
Cov khoom ntawm cov pwm tsis zoo. Qee lub sij hawm thaum tsim cov iav fwj, txhawm rau txo cov nqi, qee cov tuam txhab yuav xaiv pwm nrog cov khoom siv tsis zoo rau kev tsim khoom, yog li nws yooj yim ua rau tsis txaus vim cov khoom ntawm lub raj mis cawv pwm, thiab oxidation yog ceev heev tom qab kub kub. , yog li nws yooj yim heev. Qhov no ua rau tsim cov pits me me rau ntawm qhov chaw ntawm cov pwm, uas ua rau muaj qhov tsis zoo ntawm lub khob iav tom qab molding. Yog li ntawd, peb yuav tsum xyuam xim rau xaiv cov pwm nrog cov ntaub ntawv zoo dua thaum lub sij hawm tsim khoom, kom cov iav fwj uas tsim tawm yuav tsis muaj qhov tsis zoo.
Thawj pwm tsim yog tsis tsim nyog. Hauv kev tsim cov iav fwj, qee zaum vim qhov tsim tsis tsim nyog ntawm qhov pib pwm, pwm kab noj hniav loj dhau los yog me me dhau. Thaum lub sij hawm tsim khoom, tom qab lub gob nkag mus rau hauv cov pwm pwm, nws yog tshuab thiab kis tau unevenly, yog li ntawd thaum siv Nws yuav ua rau me ntsis ntawm lub cev ntawm lub khob lub raj mis, uas yuav cuam tshuam rau qhov zoo ntawm lub khob lub raj mis.
