PolyvinylpyrrolidoneWaxa kale oo loo yaqaan PVP, CAS nambarku waa 9003-39-8. PVP waa isku-dhismeed biyo-milmi leh oo dhammaystiran oo ka samaysan polymerN-vinylpyrrolidone (NVP)xaaladaha qaarkood. Isla mar ahaantaana, PVP waxay leedahay milmayn heer sare ah, xasilooni kiimikaad, kartida samaynta filimada, sunta hoose, jilicsanaanta jireed, nuugista biyaha iyo awoodda qoyaanka, awoodda isku-xidhka, iyo saamaynta koollada ilaalinta. Waxa ay isku dari kartaa xeryo badan oo aan dabiici ahayn iyo kuwo dabiici ah sida wax lagu daro, wax lagu daro, agabka caawinta, iwm.

Polyvinylpyrrolidone (PVP) ayaa dhaqan ahaan loo isticmaali jiray dhinacyo kala duwan sida dawooyinka, qurxinta, cuntada iyo cabitaanka, samaynta, dunta, xuubka kala soocida, iwm. sida resins sawiro, Fiber Optical, Laser discs, jiid walxaha dhimaya, iwm.

Sababta ugu weyn ee sababtaPVPWaxa loo isticmaali karaa sidii co-daadiyaha waa in isku-xidhyada ku jira molecules PVP ay ku dari karaan hydrogen-ka firfircoon ee molecules aan la milmin. Dhinaca kale, unugyo yar yar ayaa noqda amorphous waxayna galaan PVP macromolecules. Dhanka kale, isku-xidhka hydrogen ma beddelo milanka biyaha ee PVP, markaa natiijadu waxay tahay in molecules aan milmi karin ay ku kala firirsan yihiin pVp macromolecules iyada oo loo marayo isku-xidhka hydrogen, taasoo ka dhigaysa inay si fudud u milmaan. Waxaa jira noocyo badan oo PVP ah, Sideen u dooranaa qaabkaas marka aan dooraneyno. Marka qadarka (cufka) ee PVP la mid yahay, kororka milanka ayaa hoos u dhacaya habka PVP K15>PVP K30>PVP K90. Tani waa sababta oo ah saamaynta xalinta PVP lafteedu waxay isu beddeshaa siday u kala horreeyaan PVP K15>PVP K30>PVP K90. Guud ahaan, pVp K 15 ayaa inta badan la isticmaalaa.

Ku saabsan jiilka PVP: kaliya NVP, monomer, ayaa ka qaybqaata polymerization, alaabteeduna waa Polyvinylpyrrolidone (PVP). Monomer-ka NVP waxa uu maraa falcelin isku xidhid ah ama monomerka NVP waxa uu maraa falcelinta isku xidhka isku xidhka isku xidha ee wakiilka isku xidhka (oo ka kooban xeryahooda kooxeedyo badan oo aan saturated ahayn), wax soo saarkiisuna waa Polyvinylpyrrolidone (PVPP). Waxaa la arki karaa in alaabooyin kala duwan oo polymerization ah lagu soo saari karo iyada oo la xakameynayo xaaladaha habka polymerization ee kala duwan.

Waxaan fahamsanahay socodka habka PVP

Codsiga fasalka warshadaha PVP: Taxanaha PVP-K waxaa loo isticmaali karaa sida wakiilka filimada, dhumucdiisuna, saliidayn iyo xabagta warshadaha kiimikada maalinlaha ah, waxaana loo isticmaali karaa qarxinta, Moss, jel hagaajinta timaha, hagaajinta timaha, iwm. Ku darida PVP ee timaha dheeha iyo wax ka beddelayaasha daryeelka maqaarka, xumbo xasiliya shaambada, kala firdhiyaashooda iyo wakiilada xidhiidhka ee wakiilada qaabaynta hirarka, iyo kiriimka iyo muraayadaha qorraxda waxay kor u qaadi karaan saamaynta qoynta iyo saliidaynta. Marka labaad, ku darida PVP ee saabuunta waxay leedahay saameyn wanaagsan oo ka hortagga midabka waxayna kor u qaadi kartaa awoodda nadiifinta.

Codsiga PVP ee beeraha warshadaha iyo farsamada sare: PVP waxaa loo isticmaali karaa sida wakiilka daahan dusha sare ah, kala firdhiya, dhumucdiisuna, iyo xabagta ee midabada, daabacaadda khadadka, dunta, daabacaadda iyo dheehidda, iyo tuubooyinka sawirka midabka. PVP waxay wanaajin kartaa waxqabadka isku xidhka xabagta birta, dhalooyinka, caagagga iyo walxaha kale. Intaa waxaa dheer, PVP ayaa si sii kordheysa loogu isticmaalo xuubka kala-soocidda, xuubka ultrafiltration, xuubka microfiltration, xuubka nanofiltration, sahaminta saliidda, rinjiyada sawir-qaadista, rinjiyada iyo dahaarka, fiber Optical, discs laser iyo beeraha kale ee tiknoolajiyada sare ee soo baxaya.

Codsiga fasalka daawada PVP: Ka mid ah taxanaha PVP-K, k30 waa mid ka mid ah walxaha synthetic ee loo isticmaalo, inta badan wakiilada wax soo saarka, wakiilada koollada ee granules, wakiilada sii-daynta joogtada ah, adjuvants iyo stabilizers irbado, qalabyada socodka, kala firdhiyaa qaabaynta dareeraha iyo chromophores, xasiliyayaal loogu talagalay enzymes iyo daawooyinka heerkulbeegga, isku-darka isku-darka ah ee ay adag tahay in loo dulqaadan karo daawooyinka, fidiyeyaasha saliidaha indhaha, iyo dahaarka wakiilada filim-samaynta.

Polyvinylpyrrolidone iyo polymers-keeda, sida agab kiimiko ah oo cusub, ayaa si weyn loogu isticmaalaa daawada, cuntada, kiimikooyinka maalinlaha ah, daabacaadda iyo dheeynta, dahaarka midabka, agabka noolaha, agabka daaweynta biyaha iyo meelaha kale, oo leh rajooyin suuqgeynta ballaaran. Ka dib sanado badan oo sahaminta joogtada ah, waxaan soo saarnay badeecooyin kala duwan oo isku dhafan, oo ay ku jiraan kuwan soo socda:

Marka la soo koobo, taxanaha PVP ee alaabadu waxay leeyihiin waxqabad aad u wanaagsan waxaana si ballaaran loogu isticmaalaa waxyaabaha lagu daro polymer ee daawada, dahaarka, midabada, resins, khadadka fiber-ka, xabagta, saabuunta, daabacaadda dharka iyo dheehidda. PVP, sida surfactant polymer, waxa loo isticmaali karaa sida kala-firdhiye, emulsifier, dhumuc weyn, wakiilka simaynta, viscosity regulator, wakiilka dareeraha taranka, xinjirowga, qaboojiyaha, iyo saabuun ee hababka kala firdhiso kala duwan.
