Ni ubuhe busobanuro bwa fibre, selile, na selile ether kandi ni irihe tandukaniro?

Ifu ya putty igizwe ahanini nibintu bikora firime (ibikoresho byo guhuza), ibyuzuza, ibikoresho bigumana amazi, kubyimbye, defoamers, nibindi.

Fibre:

Fibre (US: Fibre; Icyongereza: Fibre) bivuga ikintu kigizwe na filime ikomeza cyangwa idahagarara. Nka fibre yibimera, umusatsi winyamanswa, fibre ya silike, fibre synthique, nibindi.

Cellulose:

Cellulose ni macromolecular polysaccharide igizwe na glucose kandi nikintu nyamukuru cyubaka urukuta rwibimera. Ku bushyuhe bwicyumba, selile ntishobora gushonga mumazi cyangwa mumashanyarazi asanzwe. Cellulose yibigize ipamba igera hafi 100%, bigatuma iba isoko nziza ya selile. Muri rusange ibiti, selile ifite 40-50%, kandi hariho 10-30% hemicellulose na 20-30% lignine.

Itandukaniro riri hagati ya selile (iburyo) na krahisi (ibumoso):

Muri rusange, ibinyamisogwe na selile ni macromolecular polysaccharide, kandi formula ya molekile irashobora kugaragazwa nka (C6H10O5) n. Uburemere bwa molekuline ya selile nini kuruta iy'ibinyamisogwe, kandi selile irashobora kubora kugirango ikore ibinyamisogwe. Cellulose ni D-glucose na β-1,4 glycoside Macromolecular polysaccharide igizwe na bonds, mugihe ibinyamisogwe bigizwe na α-1,4 glycosidic. Cellulose muri rusange ntabwo ishami, ariko ibinyamisogwe byashamiwe na 1,6 glycosidic. Cellulose ntishobora gushonga mumazi, mugihe ibinyamisogwe bishonga mumazi ashyushye. Cellulose ntiyumva amylase kandi ntabwo ihinduka ubururu iyo ihuye na iyode.

Cellulose Ether:

Izina ry'icyongereza ryaselile etherni selile ya ether, ikaba polymer ivanze hamwe na ether imiterere ikozwe muri selile. Nibicuruzwa byimiti ya selile (igihingwa) hamwe na etherification agent. Ukurikije imiterere yimiti itondekanya ibyasimbuwe nyuma ya etherification, irashobora kugabanywamo anionic, cationic na nonionic ethers. Ukurikije agent ya etherification yakoreshejwe, hariho methyl selulose, hydroxyethyl methyl selulose, carboxymethyl selulose, Ethyl selulose, benzyl selulose, hydroxyethyl selulose, hydroxypropyl methyl selulose, cyanoethyl selulose, benzyl cyanoethyl selulose, carboxymethyl hydroxy, carboxymethyl hydroxy selulose ether nayo yitwa selile, nizina ridasanzwe, kandi ryitwa selile (cyangwa ether) neza.

Uburyo bwo kubyimba bwa Cellulose Ether Thickener:

Umubyimba wa selulose ether ni umubyimba utari ionic ubyimbye cyane bitewe na hydrata no guhuzagurika hagati ya molekile.

Urunigi rwa polymer rwa selulose ether biroroshye gukora hydrogène hamwe namazi mumazi, kandi hydrogène ya hydrogène ituma igira hydrated nyinshi hamwe no guhuza molekile.

Iyoselile etherkubyimbye byongewe kumarangi ya latex, ikurura amazi menshi, bigatuma ubwinshi bwayo bwaguka cyane, bikagabanya umwanya wubusa kuri pigment, kuzuza nuduce twa latex;

Muri icyo gihe, iminyururu ya selile ya selile ihujwe no gukora imiterere y'urusobekerane rw'ibice bitatu, kandi pigment, kuzuza hamwe na latx ibice bikikijwe hagati ya mesh kandi ntibishobora gutembera mu bwisanzure.

Munsi yizi ngaruka zombi, viscosity ya sisitemu iratera imbere! Yageze ku ngaruka zo kubyimba twari dukeneye!
