Iyo inoshamisa michina ye hydroxylyl cellulose ndeyekuwedzera iyo viscosity kuburikidza nekuumbwa kweiyo intermolecular uye Intramolecular hydrogen zvisungo, pamwe nehydration uye keteni yekunetseka kwemaketani. Naizvozvo, nzira yakakora ye hydroxylyl cellulose inogona kukamurwa kuita zvikamu zviviri: imwe ibasa reIntermolecular uye Intramolecular Hydrogen zvisungo zveHydrogen. Iyo hydrophobic main main yekubatanidza nemamolekora emvura akakomberedza kuburikidza neHydrogen zvisungo, izvo zvinovandudza hunhu hwePolymer pachayo. Iyo vhoriyamu yezvikamu zvinodzora nzvimbo yekufamba yemahara yezvidimbu, nekudaro ichingowedzera zvevisangano yehurongwa; Chechipiri, kuburikidza neyekunyorwa kwemaketani anonyora, maketani cellulose maketani ari mune matatu-dimensional network network muhurongwa hwese, nekukasira nekuvandudza mavhoti.
Ngatitarisei kuti cellulose inoita sei basa rekuchengetedza system: Kutanga, basa reHydrogen Kuchengetwa kwemvura Yemahara, anoita basa rekuchengetwa kwemvura, uye rinobatsira kudzivirira kupatsanurwa kwemvura; Chechipiri, kutaurirana kwemachinguwa nemapepa emapapu emapepa anogadzira network-yakabatana network kana nzvimbo yakaparadzaniswa pakati penzvimbo, mafirita uye anodzivirira kugadzirisa.
Iko kusanganiswa kwemhando mbiri dziri pamusoro dzekuita dzinoita kuti hydroxylyl cellulose kuve nekugona kwakanaka kwazvo kugadzirisa kuchengetedza kwekuchengetedza. Mukugadzirwa kweLatex Paint, iyo Hec yakawedzera kurova uye kupararira inowedzera mugwara rekunze, iro remagetsi rekuputika rinopera, iro riri nyore kutsvedza pamwe chete, iyo viscosity system inoderera. Sezvo iyo system ine huwandu hwakawanda hwezvimwe zvikamu (pachena, mafirita, emelsions), kurongeka kwakarongeka), kurongeka kwakarongeka), kurongeka kwakarongeka hakugone kudzoreredza mamiriro ekuyambuka uye kuiswa kunyange kwenguva yakareba mushure mekunge pendi yakasanganiswa. Mune ino kesi, hec chete inovimba nezve hydrogen zvisungo. Mhedzisiro yekuchengetwa kwemvura uye kuremerwa kunodzora kugona kwemvura kweec, uye mupiro wekuparadzira uku mamiriro kune kugadzikana kwekuchengetedza kwehurongwa zvakare kwakaderedzwa. Nekudaro, iyo yakanyungudutswa hec yakanga yakafanana nehurongwa hwakasarudzika pakumhanya kwakadzika panguva yekuregedzwa Saka kuratidza yakakwira zvakanyanya kugona uye kugadzikana kwekuchengetedza. Zviripachena, chiitiko chakangofanana chedzidzo mbiri dzakakomberedza ndiko kuenderana kwekunyora kwekunyora kwemheremalose uye kuverengera kugadzikana kwekuchengetedza. Mune mamwe mazwi, iyo yakanyungudutswa uye yakapararira mamiriro emasero mumvura ichakanganisa zvakanyanya mhedzisiro uye mupiro waro wekuchengetedza kugadzikana.
