Fim ɗin Polyvinyl Alcohol (PVA) ana amfani dashi sosai a masana'antu daban-daban saboda sabiodegradability, ruwa solubility, da kuma m film-forming Properties. Duk da haka, cimma wani high quality-PVA shafi na fimyana buƙatar ainihin zaɓi na albarkatun ƙasa. Fahimtar waɗannan abubuwa masu mahimmanci yana da mahimmanci don haɓaka aikin fim, karko, da aiki.
1. Polyvinyl Alcohol (PVA) - Babban Bangaren
A zuciyar PVA fim shafi karyapolyvinyl barasa, polymer roba wanda ke ba da kyakkyawar mannewa, sassauci, da kaddarorin shinge. Matsayin kwayoyin halitta da digiri na hydrolysis na PVA kai tsaye yana tasiri gaƙarfin fim, narkewa, da juriya na sinadarai. Zaɓin madaidaicin matakin PVA yana tabbatar da kyakkyawan aiki a aikace-aikace kamar marufi, noma, da magunguna.
2. Plasticizers - Haɓaka sassauci da Ƙarfi
Ana ƙara masu filastikinganta sassauci da kayan aikin injiniyafim din PVA. Ba tare da robobi ba, fim ɗin na iya zama mai karye kuma yana iya fashewa. Na yau da kullum plasticizers amfani aPVA shafi na fimsun hada da:
•Glycerol- Plasticizer mai amfani da yawa wanda ke haɓaka sassauci da riƙe danshi.
•Polyethylene Glycol (PEG)- Inganta elasticity na fim kuma yana hana raguwa.
•Sorbitol- Yana haɓaka karko yayin kiyaye babban matakin bayyana gaskiya.
Zaɓin filastik mai dacewa yana taimakawa daidaitawaƙarfi, gaskiya, da sassaucidon buƙatun masana'antu daban-daban.
3. Crosslinking Agents - Inganta Dorewa da Ruwa Resistance
Fina-finan PVA galibi suna buƙatar wakilai masu haɗa kai zuwahaɓaka juriya na sinadarai, kwanciyar hankali, da ƙarfin injina. Wadannan jami'ai suna aiki ta hanyar ƙirƙirar haɗin sinadarai tsakanin sarƙoƙi na polymer, suna yin fim ɗin ƙarim kuma m. Wakilan haɗin kai gama gari sun haɗa da:
•Borates (Borax)- Inganta taurin fim da abubuwan mannewa.
•Glutaraldehyde- Yana haɓaka juriya na ruwa yayin kiyaye sassauci.
•Dicarboxylic acid- Ƙarfafa tsarin fim ɗin ba tare da lalata biodegradability ba.
Haɗin da ya dace na ma'aikatan haɗin gwiwa yana tabbatar da aFim ɗin PVA mai tsayi da tsayi mai tsayi.
4. Fillers - Haɓaka kayan aikin injiniya da kayan gani
Don canza launi, bayyanar, da ayyuka na suturar fim na PVA,masu cikawaana yawan karawa. Wadannan kayan zasu iya ingantafim ɗin baƙar fata, ƙarfi, da ingancin farashi. Wasu filaye da aka saba amfani da su sun haɗa da:
•Titanium Dioxide (TiO₂)- Yana ba da fari da juriya na UV.
•Silica (SiO₂)- Yana haɓaka ƙarfin fim kuma yana rage jujjuyawar ƙasa.
•Calcium Carbonate (CaCO₃)- Rage farashin samarwa yayin kiyaye amincin fim.
Yin amfani da filaye masu dacewa yana taimakawa wajen tsara fina-finai na PVA dontakamaiman aikace-aikace, kamar marufi masu lalacewa, fina-finan noma, ko jakunkuna masu narkewa da ruwa.
5. Surfactants - Inganta Rufin Uniformity
Don wani ko dam PVA fim shafi, surfactants suna da mahimmanci. Wadannan mahadirage tashin hankali, ƙyale murfin ya yada a ko'ina a cikin saman. Key surfactants da aka yi amfani da su a cikin samar da fim na PVA sun haɗa da:
•Non-ionic surfactants- Inganta jigon fim da watsawa.
•Anionic surfactants- Haɓaka kwanciyar hankali da abubuwan mannewa.
•Silicone na tushen surfactants- Rage lahani na saman kuma inganta daidaiton fim.
Zaɓin surfactant mai dacewa yana tabbatarm fim kauri da santsi, wanda ke da mahimmanci ga aikace-aikacen da ke buƙatar takamaiman kaddarorin shinge.
6. Additives - Inganta Ayyuka da Ayyuka

•UV Stabilizers– Kare daga lalacewa daga hasken rana.
•Agents na hana hana toshewa- Hana yadudduka na fim daga haɗuwa tare yayin ajiya.
•Ma'aikatan Antimicrobial- Tsawaita rayuwar rayuwar samfur ta hana haɓakar ƙwayoyin cuta.
