Tsarin Samar da PVA da Faɗin Aikace-aikace

Polyvinyl Alcohol (PVA) shine polymer roba wanda aka samar ta hanyar polymerization na vinyl acetate wanda ya biyo bayan hydrolysis. Anan ga bayyani na tsarin samar da PVA da faffadan aikace-aikacen sa:

Tsarin samarwa:

1. Polymerization na Vinyl Acetate:
   • Vinyl acetate monomers ana yin su ne ta hanyar yin amfani da mai ƙaddamarwa na kyauta a gaban mai ƙarfi ko azaman emulsion. Wannan matakin yana haifar da samuwar polyvinyl acetate (PVAc), fari, polymer mai narkewa da ruwa.
2. Hydrolysis na polyvinyl acetate:
   • Ana amfani da polymer na PVAc ta hanyar magance shi tare da maganin alkaline (kamar sodium hydroxide) a ƙarƙashin yanayin sarrafawa. Wannan halayen hydrolysis yana raba ƙungiyoyin acetate daga kashin baya na polymer, wanda ya haifar da samuwar polyvinyl barasa (PVA).
3. Tsarkakewa da bushewa:
   • Maganin PVA yana ɗaukar matakan tsarkakewa don cire ƙazanta da kuma monomers marasa amsawa. Za a bushe maganin PVA mai tsabta don samun ƙoshin PVA mai ƙarfi ko foda.
4. Ƙarin Gudanarwa:
   • Za a iya kara sarrafa nau'i na PVA ko foda zuwa nau'i daban-daban kamar granules, pellets, ko mafita, dangane da aikace-aikacen da aka yi niyya.

Faɗin Aikace-aikace:

1. Adhesives da masu ɗaure:
   • Ana amfani da PVA a matsayin mai ɗaure a cikin manne, gami da manne itace, manne takarda, da adhesives na yadi. Yana ba da ƙarfi mannewa zuwa daban-daban substrates kuma yana ba da kyawawan kaddarorin yin fim.
2. Textiles da Fibers:
   • Ana amfani da filaye na PVA a aikace-aikacen yadi kamar saƙa, saka, da yadudduka marasa sakawa. Suna baje kolin kaddarorin kamar ƙarfin ƙarfi mai ƙarfi, juriya, da kwanciyar hankali na sinadarai.
3. Rufe Takarda da Girma:
   • Ana amfani da PVA a cikin suturar takarda da ƙirar ƙira don haɓaka santsi, ɗab'i, da manne tawada. Yana haɓaka ƙarfi da ƙarfin samfuran takarda.
4. Kayayyakin Gina:
   • Ana amfani da kayan aikin tushen PVA a cikin kayan gini kamar ƙari na turmi, tile adhesives, da siminti. Suna haɓaka iya aiki, mannewa, da dorewar samfuran gini.
5. Fina-finan Marufi:
   • Ana amfani da fina-finai na PVA don aikace-aikacen marufi saboda kyawawan kaddarorin shinge, juriyar danshi, da haɓakar halittu. Ana amfani da su a cikin kayan abinci, fina-finai na noma, da aikace-aikacen marufi na musamman.
6. Kayan shafawa da Kayayyakin Kulawa na Kai:
   • Ana amfani da PVA a cikin kayan kwalliya da samfuran kulawa na sirri kamar gels ɗin gashi, creams, da lotions. Yana ba da kaddarorin samar da fim, yin kauri, da tasirin ƙarfafawa.
7. Aikace-aikacen Likita da Magunguna:
   • Ana amfani da PVA a cikin aikace-aikacen likita da magunguna kamar tsarin isar da magunguna, suturar rauni, da murfin ruwan tabarau. Yana da jituwa, ba mai guba ba, kuma yana nuna kyakkyawan narkewar ruwa.
8. Masana'antar Abinci:
   • Ana amfani da PVA azaman ƙari na abinci a cikin aikace-aikace daban-daban kamar fina-finai masu cin abinci, ɓoye abubuwan dandano ko abubuwan gina jiki, kuma azaman wakili mai kauri a cikin samfuran abinci. Ana la'akari da shi lafiya don amfanin ɗan adam.

A taƙaice, Polyvinyl Alcohol (PVA) wani nau'in polymer ne tare da aikace-aikace iri-iri a cikin masana'antu kamar su adhesives, yadi, takarda, gini, marufi, kayan kwalliya, likitanci, magunguna, da abinci. Kaddarorinsa na musamman sun sa ya dace da aikace-aikacen daban-daban waɗanda ke buƙatar ƙirƙirar fim, m, ɗaure, shinge, da kaddarorin masu narkewar ruwa.
