Usetyenziso oluNxulumeneyo lwePoly(1-vinylpyrrolidone-co-vinyl acetate) iCopolymer: Isisombululo esithembisayo sokwenza ifilim.

Poly(1-vinylpyrrolidone-co-vinyl acetate)I-copolymer, ekwabizwa ngokuba yiPPVVA, yipolymer eguquguqukayo enikezela uluhlu olubanzi lwezicelo ngenxa yeempawu zayo ezintle zokwenza ifilimu.I-PVPVA ine-solubility egqwesileyo emanzini kunye ne-solvents ye-organic kwaye inokuthi ifakwe ngokulula kwiintlobo ezahlukeneyo zokuqulunqa.Ukongeza kwi-thermal stable kunye nokumelana nokuthotywa, i-copolymer iphinda ibonise ukuhanjiswa kombane okuphuculweyo, okwenza ukuba ilungele ukusetyenziswa kwi-electronics kunye nezicelo zokugqoka eziqhubayo.Kule bhlog, siza kuphonononga iimpawu ezizodwa kunye nokusetyenziswa okunokwenzeka kwePPVVA.

1. Ukwenziwa kwefilimu okugqwesileyo:

Okokuqala, ii-copolymers ze-PVVA zivelele kwiimpawu zazo ezibalaseleyo zokwenza ifilimu.Xa isetyenziswe njengesithako ekuqulunqweni okufana neengubo, i-adhesives kunye nemveliso yokunyamekela komntu, inikeza iifilimu ezigudileyo, ezifanayo eziphakamisa ukubonakala kunye nokuqina kwemveliso.Izakhono zokwenza ifilimu ye-PVPVA iqinisekisa ukugubungela ngokufanelekileyo kunye nokubambelela, ukuphucula ukusebenza kwiintlobo ezahlukeneyo zezicelo.

2. Ukunyibilika emanzini kunye nezinyibilikisi eziphilayo:

I-PVPVA copolymers ibonisa ukunyibilika okugqwesileyo emanzini kunye neentlobo ezahlukeneyo ze-solvents eziphilayo.Le propati ivumela ukuba idibaniswe ngokulula kwiindlela ezahlukeneyo kunye neenkqubo, okwenza ukuba ibe yinto edibeneyo kumashishini ahlukeneyo.Ukususela kumachiza ukuya kwi-sprays yeenwele, i-PVVA iyahambelana kwaye izinzile kwii-solvents ezahlukeneyo, ibonelela ngeefomyula ngokuguquguqukayo ekuphuhlisweni kwemveliso.

3. Ukuguqulwa kokuqhutywa kweengubo zombane kunye ne-conductive:

Ikhono elikhethekileyo lokutshintsha i-conductivity ye-PPVVA yenza kube yinto efanelekileyo kwi-electronic and conductive coating applications.Ngokulungiswa kwesiko, i-copolymer inokufezekisa iipropathi zombane ezifunwayo, iyenze ibe yinto efanelekileyo kwizicelo ezinjengezinzwa, iibhodi zeesekethe eziprintiweyo kunye neengubo ezichasene ne-antistatic.Ikhono le-PVPVA lokubonelela nge-conductivity ngaphandle kokuchaphazela iipropati zokwenza ifilimu yenza kube lukhetho oluhle kakhulu kwezi zicelo ezizodwa.

4. Uzinzo lwe-Thermal kunye nokumelana nobushushu:

Olunye uphawu oluphawulekayo lwe-PVPVA copolymer kukuzinza kwayo kwe-thermal kunye nokuchasana nokuthotywa.Oku kuyenza ilungele izicelo ezifuna ukuvezwa kumaqondo obushushu aphezulu okanye imo engqongileyo erhabaxa.Kungakhathaliseki ukuba kwi-adhesive formulations ye-automotive assembly okanye i-coatings yokukhusela kwizixhobo zoshishino, i-PVVA iqinisekisa ubomi obude kunye nokuqina kwiimeko ezinzima.

Poly(1-vinylpyrrolidone-co-vinyl acetate)I-copolymer yimathiriyeli esebenzayo eneempawu ezibalaseleyo zokwenza ifilim, ukunyibilika emanzini kunye nezinyibilikisi ze-organic, ukuhanjiswa kombane, kunye nokuzinza kwe-thermal.Ezi mpawu ziyenza ibe sisithako esibalulekileyo kumashishini ahlukeneyo, kubandakanywa izinto zokuncamathelisa, iingubo, amayeza kunye ne-elektroniki.I-PVPVA yenza ukuba abavelisi baphuhlise iimveliso ezintsha kunye nokusebenza okuphuculweyo kunye nokuqina.Njengophando lwesayensi yepolymer kunye nophuhliso oluqhubela phambili, silindele ukubona izicelo ezinomdla ngakumbi zePPVVA kwixesha elizayo.
