Kiimarishaji cha Emulsion & Binder
PVA inaweza kutumika sana kama koloidi ya kinga au kinene kwa ajili ya upolimishaji wa emulsion ya vinyl acetate (VAc) au VAc/acrylate.ina sifa zifuatazo: unamata bora;kuongezeka kwa kasi ya awali na kiwango cha kukausha wakati unatumiwa na kichungi;upinzani bora kwa mafuta;filamu bora.
Katika utengenezaji wa nyuzi
Matumizi mawili muhimu ya PVA yanapaswa kutumika kama vinylon feedstock na sizing kikali kwa nguo.Kama malighafi ya vinylon fiber, ina faida ya kuwa juu katika nguvu, kunyonya unyevu, upinzani abrasion, upinzani jua, upinzani kutu na nyeupe katika rangi.Inaweza pia kusokota kwa pamba, pamba na nyuzi za viscose au kusokotwa yenyewe.Kama wakala wa kupima nguo, haitaharibika au kuharibika kwa kushikamana vizuri na pamba, katani, polyester na nyuzi za viscose.
Pulp & PaperPVA imepata matumizi makubwa katika matibabu ya uso wa karatasi kwa kuwa ina mshikamano bora na mtawanyiko na haitaathiri mali ya viunga vingine vinavyotumiwa pamoja.Faida za kutumia PVA:Nguvu ya uso (uwezo wa kuchapisha);Nguvu pamoja na mhimili wa Z(nguvu ya ndani ya karatasi);Upinzani wa kukunja;Ustahimilivu wa abrasive;Ulaini ulioboreshwa;Ung'ao ulioboreshwa wa uso;Kuongeza upinzani dhidi ya mafuta na kutengenezea (kizuizi).
Filamu
PVA inaweza kutumika kutengeneza filamu mumunyifu katika maji na filamu inayostahimili maji. tasnia ya kifurushi, sio tu kwa nguo, bali pia kwa kemikali, chakula, kemikali za kila siku, kemikali za kilimo, rangi, na kadhalika.
Kiimarishaji cha Mtawanyiko
PVA, ambayo ni bora katika ulinzi wa koloidi na ina shughuli bora zaidi ya uso, mara nyingi hutumiwa kama kiimarishaji cha utawanyiko kwa upolimishaji wa kusimamishwa kwa monoma ya kloridi ya vinyl (VCM).Utendaji wa resin ya PVC unaweza kuboreshwa sana kwa kuchagua daraja la PVA linalofaa na kiwango sahihi cha upolimishaji na hidrolisisi.
Tuna zaidi ya ghala la 1000m2 la PVA ili kuhakikisha ugavi thabiti na bei ya ushindani kila wakati.
