Umthengisi wePolyvinyl Alcohol (PVA/PVOH) eMzantsi Afrika

I-PVA efakwe ngokupheleleyo nangokuyinxenye kwii-hydrolyzed ukuze kwenziwe ubungakanani belaphu, izinto zokuncamathelisa, ukugquma iphepha, i-emulsion polymerisation, kunye neefilimu zokuthintela.

I-PVA kwizicelo zeLaphu nePhepha

I-Polyvinyl alcohol iveliswa yi-hydrolysis ye-polyvinyl acetate kwaye ifumaneka kwiindidi ezahlukeneyo ukusuka kwi-hydrolysed engaphelelanga (88 mol%, ukunamathela okuhle kunye nokuguquguquka) ukuya kwi-hydrolysed epheleleyo (99 mol%, umqobo ongcono we-oxygen kunye nokumelana namanzi). Abavelisi belaphu basebenzisa i-PVA ukwenza ubungakanani beentambo ze-warp ngaphambi kokuluka, benciphisa ukwaphuka kwi-loom kwaye baphucule ukuluka. Iifektri zephepha zisebenzisa i-PVA kubungakanani bomphezulu kunye nokugquma ukuphucula amandla omphezulu kunye nokuprintwa kwawo.

Ukukhethwa kwamaBanga kunye nokuNikezelwa

I-Terracore inemigangatho emininzi ye-PVA egubungela uluhlu oluphantsi, oluphakathi, noluphezulu lwe-viscosity kwiinkcukacha ezifakwe i-hydrolyzed ngokupheleleyo kunye ne-hydrolyzed ngokupheleleyo. Ifumaneka kwiingxowa ezingama-25 kg kwiipallet. I-COA ixela inqanaba le-hydrolysis, i-viscosity, kunye nomxholo womlotha. I-SDS inikezelwa.
