1 、 Ua rau cov khoom ua tiav tsis zoo
1-1 pwm tiav tsis siab
1-2 pwm kub tsawg dhau
2 、 Paub txog kev paub
2-1 vim tias qhov ua tiav saum npoo ntawm cov khoom (thaj tsam tag nrho hauv kev sib tiv tauj nrog lub pwm) yog txiav txim siab los ntawm cov nplaim npoo ntawm cov pwm, yog tias pwm tiav qhov tsis zoo, qhov ua tiav ntawm cov khoom yuav tsis zoo vim lub me me concave thiab convex chaw, yog li nyob rau hauv cov khoom siv pob tshab, lub teeb xa hluav taws xob tseem yuav poob, thiab lub pob tshab yuav poob.
2-2 vim tias pwm kub siab, qhov ua tiav tiav yuav zoo dua, yog li cov dej kub kom sov ntau yuav siv rau hauv cov pwm kom qhov pwm kub nyob ntawm ib qho nqi, kom cov cua sov ntawm cov khoom xa mus sai, kom lub voj voog tuaj yeem ua kom luv thiab cov khoom lag luam nrog cov kev ntxhov siab me me tuaj yeem tau txais.
2-3 txhawm rau kom tau txais cov pwm nrog kev ua tiav siab, nws yog ib qho tsim nyog rau plating nyuaj chromium nyob rau saum npoo ntawm pwm cov khoom lag luam, tab sis nws nyuaj rau kev kho cov pwm puas.
3 、 Kev daws
3-1 instant: nce pwm kub
3-2 lub sij hawm luv luv: txhim kho qhov saum npoo ntawm cov khoom lag luam pwm
3-3 lub sijhawm ntev: siv cov khoom siv pwm nyuaj thiab pob zeb diamond sib tsoo hmoov rau sib tsoo.
4 、 Vim cov khoom sib txawv:
4-1 vim tias cov ntaub ntawv tsis zoo lub cev tiv thaiv nrog cov pwm khoom lag luam saum npoo, uas yog hais, lawv tau ua tiav tam sim ntawd, thiab tsis tuaj yeem hais tau zoo nrog cov khoom lag luam pwm. Tsis tas li ntawd, cov evaporation ntawm cov hluav taws xob hauv cov khoom siv thiab cov khoom siv nrog qhov tsis txaus ua ntej ziab muaj nyob nruab nrab ntawm cov khoom thiab cov pwm tom qab sib tiv tauj thiab hws nrog cov pwm, uas ua rau cov khoom lag luam ua tsis tiav.
4-2 cov ntaub ntawv nrog daim ntawv zoo rau ua tiav: GPPS, ABS, pp
