Budada Putty waxay inta badan ka kooban tahay walxaha filim samaynta (qalabka isku xidhka), buuxinta, wakiilada biyaha, dhumucyada, defoamers, iwm Walxaha kiimikada caadiga ah ee kiimikada caadiga ah ee budada putty inta badan waxaa ka mid ah: cellulose, istaarijka pregelatinized, istaarijka ether, alkolada polyvinyl, budada cinjirka ah, iwm.
Fiber:
Fiber (US: Fiber; English: Fiber) waxaa loola jeedaa walax ka kooban fiilo joogto ah ama joogsan. Sida faybarka dhirta, timaha xoolaha, xuubka xariirta, fiber synthetic, iwm.
Cellulose:
Cellulose waa polysaccharide macromolecular oo ka kooban gulukoos waana qaybta ugu muhiimsan ee gidaarada unugyada dhirta. Heerkulka qolka, cellulose kuma milmo biyaha ama dareerayaasha dabiiciga ah ee caadiga ah. Maaddada cellulose ee suufku waxay ku dhowdahay 100%, taas oo ka dhigaysa isha ugu dabiiciga ah ee cellulose. Guud ahaan alwaax, cellulose waxay xisaabisaa 40-50%, waxaana jira 10-30% hemicellulose iyo 20-30% lignin.
Farqiga u dhexeeya cellulose (midig) iyo istaarijka (bidix):
Guud ahaan, istaarijka iyo cellulose labaduba waa polysaccharides macromolecular, iyo caanaha molecular waxaa lagu sheegi karaa sida (C6H10O5) n. Miisaanka molecular ee cellulose wuu ka weyn yahay kan istaarijka, cellulose waa la kala goyn karaa si loo soo saaro istaarijka. Cellulose waa D-glucose iyo β-1,4 glycoside macromolecular polysaccharides oo ka kooban curaarta, halka istaarijku uu sameeyay α-1,4 glycosidic bonds. Cellulose guud ahaan ma aha mid laami ah, laakiin istaarijka waxaa laashay 1,6 glycosidic bonds. Cellulose si liidata ugu milmay biyaha, halka istaarijku ku milmay biyo kulul. Cellulose waa dareen la'aan amylase oo ma rogto buluug marka ay la kulmaan iodine.
Eter cellulose:
Magaca Ingiriiska eeether cellulosewaa ether cellulose, kaas oo ah xarun polymer ah oo leh qaab dhismeed oo ka samaysan cellulose. Waa sheyga falcelinta kiimikaad ee cellulose (dhirta) oo leh wakiilka etherification. Marka loo eego kala soocida qaabdhismeedka kiimikada ee beddelka ka dib etherification, waxaa loo qaybin karaa anionic, cationic iyo ethers nonionic. Iyada oo ku xidhan wakiilka etherification loo isticmaalo, waxaa jira cellulose methyl, hydroxyethyl methyl cellulose, carboxymethyl cellulose, ethyl cellulose, benzyl cellulose, hydroxyethyl cellulose, hydroxypropyl methyl cellulose, cyanoethyl cellulose, benzyl cyanoethyl cellulose ah, carboxymethyl hydroxyethyl cellulose ah, cellulose ah cyanoethyl iyo warshadaha cellulose carboxymethyl. ether waxa kale oo loo yaqaan cellulose, kaas oo ah magac aan joogto ahayn, waxaana loo yaqaannaa cellulose (ama ether) si sax ah.
Farsamaynta Dhumucda ee Cellulose Ether Thickener:
Dhumucyada ether-ka Cellulose waa dhumucyo aan-ionic ahayn oo dhumucdiisu badan tahay fuuq-baxa iyo isku-xidhka u dhexeeya molecules.
Silsiladda polymer ee ether-ka cellulose waa sahlan tahay in la sameeyo bond hydrogen iyo biyaha ku jira, iyo bond bond ka dhigaysa in ay leedahay fuuq sare iyo is dhex-molecular dhexda.
Markaether cellulosedhumucdiisuna waxa lagu daraa rinjiga cinjirka, waxa ay nuugtaa xaddi badan oo biyo ah, taas oo keenaysa in mugga u gaar ah si weyn u ballaariyo, hoos u dhac ku meel bannaan ee midabada, buuxinta iyo qaybaha cinjirka;
Isla mar ahaantaana, silsiladaha molecular ether cellulose waxay isku xiran yihiin si ay u sameeyaan qaab-dhismeedka shabakad saddex-geesood ah, iyo midabada, buuxinta iyo qaybaha cirridka ayaa ku wareegsan bartamaha mesh oo aan si xor ah u socon karin.
Labadan saameyn, viscosity ee nidaamka waa la wanaajiyey! Waxaan gaarnay saameynta dhumucda aan u baahanahay!
