1, Lawv yog tag nrho cov ntaub ntawv ua yeeb yaj kiab. PP cov ntawv hluavtaws yog dawb. Cov ntawv pearlescent muaj cov nyhuv glittering ntawm cov khoom tshwj tsis yog dawb. Tom qab muab tshuaj txhuam nrog PP cov ntawv hluavtaws, nws tuaj yeem raug tshem tawm thiab rov muab dua, tab sis cov ntawv pearlescent tsis zoo. Tom qab raug tshem tawm, nws tsis tuaj yeem siv dua, vim tias qhov chaw yuav pom cov txiv kab ntxwv tev.
2, Vim tias PP cov ntawv hluavtaws muaj cov yam ntxwv ntawm ob qho tib si yas thiab ntawv, nws tau siv dav hauv ntau yam, feem ntau hauv peb yam hauv qab no:
1. Kev luam ntawv zoo. Xws li cov ntawv tshaj tawm, duab, duab, duab qhia chaw, daim ntawv qhia hnub, phau ntawv, thiab lwm yam.

3, Cov ntawv hluavtaws nrog PP raws li cov khoom siv tseem ceeb ntawm cov ntawv pearlescent muaj qis dua qhov tshwj xeeb, zoo rigidity thiab zoo tiv thaiv cov cuab yeej tshaj li cov ntaub ntawv hluavtaws, thiab feem ntau yuav hloov cov ntawv hluavtaws ntawm cov ntawv ntuj. Yog li ntawd, nws yog qhov nyuaj rau kev paub qhov txawv ntawm qhov saum npoo thiab cov ntawv hluavtaws, thiab nws yog qhov zoo tshaj plaws kom paub qhov txawv ntawm lawv tsuas yog los ntawm sab nraud.
Tib neeg kev vam meej xav tau cov peev txheej uas yuav ua rau muaj kev puas tsuaj ib puag ncig. Raws li pearlescent ntawv tsis yog ua los ntawm ntoo cov ntaub ntawv, nws yog tib yam khoom uas yuav txo tau ib puag ncig kev puas tsuaj.
Nws tuaj yeem rov siv tau los txo cov peev txheej pov tseg. Tom qab siv, cov ntawv pearlescent tuaj yeem siv dua, crushed, thiab granulated, thiab tom qab ntawd siv los ua cov khoom siv raw rau kev tsim cov yas pallets thiab cov khoom txhaj tshuaj. Yog li ntawd, nws tuaj yeem rov siv dua los txo cov peev txheej pov tseg.
