Ukusebenza okugqwesileyo komgangatho ophezulu wepoly (1-vinylpyrrolidone-vinyl acetate) evela kubavelisi abadumileyo

Umzi-mveliso owaziwayo womgangatho ophezulu wePoly(1-vinylpyrrolidone-co-vinyl acetate

Xa kuziwa kwiipolymers ezikumgangatho ophezulu, igama elinye livelele kwishishini - i-poly (1-vinylpyrrolidone-co-vinyl acetate).Le copolymer, edityaniswe ne-vinylpyrrolidone (VP) kunye ne-vinyl acetate (VA) ngokusebenzisa i-polymerization ye-radical yamahhala, yonwabela udumo oluphezulu kumashishini ahlukeneyo.Iimpawu zayo ezigqwesileyo zenza ukuba ibe sisithako esiyimfuneko kwiimveliso ezininzi.Kule bhlog, siza kujonga ngakumbi kwiipropathi zale polima yeprimiyamu evela kumenzi owaziwayo kwaye sijonge ukuba kutheni ithandwa kangaka.

Ubuninzi bezinto ezininzi (I-1-vinylpyrrolidone-vinyl acetate) yenye yeenzuzo zayo ezibalulekileyo.Ubume bayo beekhemikhali buvumela ukuba ibonise ukunyibilika okugqwesileyo kumanzi kunye nezinyibilikisi zendalo.Le propati ikhethekileyo yenza ukuba ilungele iintlobo ezahlukeneyo zezicelo ezifana ne-adhesives, i-coatings, kunye neenkqubo zokuhanjiswa kweziyobisi.Ukukwazi kwe-copolymer ukunyibilikisa zombini i-hydrophilic kunye ne-lipophilic substances yenza ukuba ibe yindlela eguquguqukayo kumashishini ahlukeneyo.

Ukongeza kokuguquguquka, i-copolymer inekhono elihle kakhulu lokwenza ifilimu.Xa isetyenziswe kwiindawo eziphezulu, yenza ifilimu efanayo, ecacileyo, eyenza ibe yinto efanelekileyo yokugqoka kunye neengqimba zokukhusela.I-poly high-quality (1-vinylpyrrolidone-vinyl acetate) iqinisekisa indawo epholileyo kunye neyomeleleyo, inika ukhuseleko kumswakama, ukushisa kunye nokubetha.Le propati yenza isithako esiphambili kwimveliso yepeyinti, ii-inki kunye neengubo zamashishini.

Enye yezona zinto ziphawuleka kakhulu kule polima ikumgangatho ophezulu bubuchule bayo bokudibanisa.Ngenxa yesakhiwo sayo semolekyuli, i-poly(1-vinylpyrrolidone-vinyl acetate) inoncanyathiso oluqinileyo kwiindawo ezahlukeneyo, kubandakanya iglasi, isinyithi kunye neeplastiki.Oku kwenza ukuba kube yinto ebalulekileyo kwi-adhesive, glue kunye ne-tape formulations.Amandla ayo aphezulu ebhondi kunye nokuxhathisa ukufuma kuqinisekisa iibhondi ezihlala ixesha elide nakwiimeko ezinzima.

I-Poly (1-vinylpyrrolidone-vinyl acetate) iyaziwa ngokuzinza kwayo okugqwesileyo kunye nokuhambelana nezinye izinto.Iimpawu zayo zokulwa ne-antioxidant, ukuxhathisa kwimitha ye-UV kunye nokuchasana nokuguquguquka kweqondo lokushisa kwenza kube yinto efanelekileyo kwiintlobo ezahlukeneyo zemiqulu.Nokuba isetyenziselwa amayeza, izithambiso okanye usetyenziso lweshishini, le copolymer inika uzinzo kunye nokuqina.Ukongeza, ukuhambelana kwayo kunye nezongezo ezahlukeneyo kunye nezithako ezisebenzayo kuphucula ukusebenza kunye nokusebenza kwemveliso yokugqibela.

Isishwankathelo, umgangatho ophezulu wepoly (1-vinylpyrrolidone-co-vinyl acetate) ubonakalise ukuba yipolymer engabalulekanga kumashishini angenakubalwa.I-solubility yayo egqwesileyo, amandla okwenza ifilimu, iipropati zokubambelela, ukuzinza kunye nokuhambelana kwenza kube yinto yokuqala yokukhetha abavelisi kunye nabavelisi.Nokuba ukhangela isithako esisebenza ngeendlela ezininzi zokwaleka, izinto ezincamathelayo okanye iinkqubo zokuhanjiswa kweziyobisi, le copolymer iqinisekisa ukusebenza okugqwesileyo kweklasi.Themba le polima ikhethekileyo ukuze uvule amandla okwenyani emveliso yakho.
