Cellulose eraification shanduko

01. Nhanganyaya yeCellulose

Cellulose ndeye macromolecular polysaccharide yakaumbwa ne glucose. Kusakwana mumvura uye general organic sol sol. Icho chinhu chikuru chemadziro ezvimedu madziro, uye zvakare ndiyo yakapararira zvakanyanya uye yakawanda yakawanda polysacchari mune zvakasikwa.

Cellulose ndiyo yakanyanya kuwanzosvitswazve bhuku repasi, uye zvakare ndeyakasikwa polymer nekuunganidzwa kukuru. Iyo ine zvakanakira kuvandudzwa, zvizere zvipenyu zvizere, uye zvakanaka biocomputer.

02. Zvikonzero zvekugadzirisa cellulose

Cellulose macromolecules ine nhamba huru ye -Oo mapoka. Nekuda kwemhedzisiro yehydrogen zvisungo, simba pakati paMacromolecules rakakura kwazvo, iyo ichatungamira kune yakakura yekunyungudutsa】 h; Kune rimwe divi, pane zvindori mu cellulose macromolecules. Kufanana nechimiro, kuomarara kweiyo molecular keteni yakakura, iyo ichatungamira kune diki yekunyungudika entropy shanduko δs. Izvi zviviri zvikonzero zvinoita kuti tembiricha yemulten cellen cellen cellen cellen cellen cellen Naizvozvo, kana cellulose ichipiswa kune imwe tembiricha, mafa anozoonekwa phenomenson kuti mheremerwa ada isati yatanga kunyungudika, saka, iyo yekugadziriswa kweCellulose zvinhu hazvigone kuve kwekutanga kunyungudika uyezve kuumba.

03. Kukosha kweCellulose Kugadziridzwa

Nekuderera zvishoma nezvishoma kwezvinhu zveFossil uye zvinonyanya kuitika zvemamiriro ekunze zvakakonzerwa nemwenje maFibheri, kushandisirwa uye kushandiswa kwezvinhu zvakasikwa zvasara zvinhu zvinopisa izvo vanhu vanoteerera. Cellulose ndiyo yakanyanya kuvhunduka zvakanyanya zvisikwa zvakasikwa mune zvakasikwa. Iyo ine zvinhu zvakanakisa senge zvakanaka hygrapicity, antistatic mhepo, yakasimba mhepo yekufungidzira, yakanaka yekudyara, yakakwana kupfeka, iri nyore machira, uye biodegradability. Iyo ine hunhu husingaenzaniswi nemakemikari machemaketi. .

Ma Cellulose Molecules ane nhamba huru yemapoka ehydroxyl, ayo ari nyore kuumba intramolecular uye intermolecular uye yekuita hydrogen zvisungo, uye kuora pakupisa kwakanyanya pasina kunyungudika. Nekudaro, cellulose ine chekuita zvakanaka, uye chisungo chayo cheHydrogen chinogona kuparadzwa nemakemikari kugadziridzwa kana kugadzira maitiro, izvo zvinogona kunyatsoburitsa iyo yekunyora pfungwa. Sezvinonyanya kugadzirwa zvigadzirwa zveindasitiri, zvinoshandiswa zvakanyanya muzvinyorwa, kupatsanurwa kwepurasitiki, mapurasitiki, fodya uye zvipuka.

04. Cellulose eraification shanduko

Cellulose ether rudzi rwemuterevhizheni inobviswa yakawanikwa nekuchinja shanduko ye cellulose. Iyo inoshandiswa zvakanyanya nekuda kwekukakavara kwayo kwakanaka, emulsifing, kumiswa, kuumbwa kwefirimu, kuchengetedza mari, kunyorovesa, uye kuderedza zvinhu. Inoshandiswa mukudya, mushonga, pepa kugadzira, pendi, kuvaka zvinhu, nezvimwe.

Kuwedzera kweCellulose inhevedzo yerudzi kunogadzirwa neiyo maitiro eHydroxyl mapoka paCellulose Molecular Cain ine alkylating vamiriri pasi peAlkaline mamiriro. Iko kunwa kwehydroxyl mapoka anodzora huwandu hwenzvimbo yekudyara hydrogen yekudzora mauto eCelluru, nekuvandudza maitiro ekugadzirisa, uye panguva imwe chete kuderedza nzvimbo yekunyungudika yemhereman.

Mienzaniso yemhedzisiro yekuchinja shanduko pane mamwe mabasa e cellulose:

Kushandisa machira akanyatsonongedzerwa, vaongorori vakashandisa matanho ekunyora. Uchishandisa imwe-nhanho yekuzadzisa maitiro, iyo yakagadzirwa carboxymethyl hydroxyprishlpropyl cellulose ine yakanaka yemunyu kurwisa, acid kuramba uye solidhi. Nekuchinja huwandu hwehuwandu hwehuwandu hweropa uye chloroacetic acid, zvigadzirwa zvine mwero mauto emhando uye hydroxyprupropyl zviri zvirimo zvinogona kugadzirira. Mhedzisiro yebvunzo inoratidza kuti iyo carboxymethyl hydroxyprichcyl cellylosel cellyproproproprocess neyakaipisisa yekugadzira, uye chigadzirwa chakawedzera kupokana nekuita zvinyoronyoro uye zvakabatana.

05. Tarisiro yeCellulose eraification shanduko

Cellulose imimwe yemakemikari yakakosha uye makemikari zvisakakura zvinhu zvakapfuma mune zviwanikwa, zvakasvibirira uye zvakatipoteredza hushamwari, uye kuvandudza. Iyo DEVENTIVES yeCellulose ertheification shanduko ine mashandiro akanakisa, akasiyana siyana ekushandisa uye anoshandisa zvakanaka kushandisa, uye kuzadzisa zvinodiwa zvehupfumi hwenyika kusvika pamwero mukuru. Uye zvido zvekuvandudza munharaunda, nekuenderera mberi kwehunyanzvi hwekutengeserana mune ramangwana, kana nzira dzekushandiswa kweCellulose dzinogona kunyorwa, ivo vanozobatwa zvizere uye vanoziva huwandu hwakawanda hwekushandisa .
