Kabedo ma pire tek me tic kwede
PVA ki tiyo kwede i tic me yubu bongo. En tiyo calo gin ma pimo dit pa bongo, ma medo teko ki bedo maber i kare me tweyo bongo. Man konyo me dwoko piny tur ki medo rom pa bongo ni. Iyonge yub me tweyo bongo, PVA ki twero kwanyo ne mayot ki lwoko, kun weko bongo ni bedo ki kit ne macon. Medo ikom meno, PVA ki tiyo kwede me yubu bongo ki jami ma mako bongo, ma miyo bongo maber ki rii.
I tic me yubu papara, PVA ki tiyo kwede me pimo dit pa karatac ki gin ma mako ne. Ma calo gin ma ki tiyo kwede me pimo dit pa karatac, en medo tek pa papara, teko, ki kit ma ki twero goyo kwede. En yubu gin ma tidi, ma nen maber i kom karatac, ma gengo ink me nya ki medo rwom me cal ma ki goyo. Ma calo gin ma mako jami, PVA ki tiyo kwede me yubu papara ma ki keto i kome ki papara, ma medo rwate i kin papara ma ki keto iye ki gin ma ki keto piny, ki medo teko ki rii pa jami ma ki yubu ki papara.
PVA bene obedo gin ma pire tek i tic me moko jami. Tye ki jami ma mako jami maber, tutwal pi jami ma tye ki buru calo bao, papara, ki bongo. Gin ma ki lwongo ni PVA - based adhesives are water - soluble, yot me tic kwede, ki tye ki teko me mako maber. Ki tiiyo kwede i gedo, kom ki meja, ki yubu jami ma pat pat.

I dul ma kwako umu, PVA ki tiyo kwede ma calo gin ma yubu filim. En yubu gin ma nen maleng, ma twero loko, ki ma pe twero donyo i pii i kom gin ma ki keto i kome, ma miyo gwok i kom yamo, jami ma ki lwongo ni chemicals, ki lero UV. PVA - ma ki yubu ki jami ma ki lwongo ni PVA pol kare ki tiyo kwede me gwoko yat, nyonyo, ki jami ma ki yubu ki plastik. Gin bene ki tiyo kwede calo gin ma ki lwongo ni primer onyo intermediate coating me medo rwate ki tic pa gin ma ki keto i wiye.
