Ibigize ibikoresho bibisi

Hariho ubwoko bwinshi bwibikoresho bibisi, ariko ibihimbano byabo byibanze bifite itandukaniro rito, cyane cyane igizwe nisukari nisukari.

. Ibikoresho bitandukanye byibimera bifite ibikubiye muri buri kintu. Ibikurikira byerekana muri make ibice bitatu byingenzi byo gutera ibikoresho bibisi:

Cellulose Ether, Lignin na Hemicurullese.

1.3 Ibigize Ibikorwa byibanze bya Ibimera Ibikoresho

1.3.1.1 Celeulose

Cellulose ni PILYSACOLECULS POLYSACHALULLUDE igizwe na D-glucose hamwe na β-1,4 glycosic. Nibyishimo kandi byinshi kwisi.

Polymer. Imiterere yayo ya fotoimique ihagarariwe na Hawworty formulaire hamwe nintebe ihuza imiterere yububiko, aho n ni urwego rwa polysaccharide.

1.4 Imiterere yimiti ya selile

1.3.1.2

Igice cyibanze cya Ligin ni Phenylpropane, noneho bihujwe na CC Bonds na Ethers Bonds.

Andika Polymer. Mu rutonde rw'ibihingwa, urwego rwo guhagarika rurimo abantu benshi,

Ibirimo byateye imbere byagabanutse, ariko ibintu bya Lignin byiyongereye mu cyinjiriro y'urukuta rwa kabiri. Nkibintu byibasiye intera, Ligin na Hemifibrils

Bose hamwe buzuza hagati ya fibre nziza y'urukuta rw'akagari, bityo bagakomeza urukuta rw'akagari k'urukuta rw'ibimera.

1.3.1.3 Hemicurullese

Bitandukanye na Ligirin, Hemicurullese ni hethepopolymer yari igizwe nubwoko butandukanye bwa monosaccharides. Ukurikije ibi

Ubwoko bw'isusu no kuba ahari cyangwa kubura amatsinda ya Acyl birashobora kugabanywa muri glucomannan, ArabinoSyl (4-o-methylgLaronICIC acide) -Ibinyamerika,

Galactosyl Glucomannan, 4-O-methylgLanic acid Xylan, ArabinoSyl Galactan, nibindi.

Mirongo itanu ku ijana by'ibiti ni xylan, biri hejuru ya microfibrils ya selile kandi bifitanye isano na fibre.

Bakora urusobe rwa selile zifitanye isano cyane.

1.4 Intego yubushakashatsi, akamaro nibiri muriyi ngingo

1.4.1 Intego n'akamaro k'ubushakashatsi

Intego yubu bushakashatsi ni uguhitamo amoko atatu uhagarariye binyuze mu gusesengura ibice byibikoresho bimwe bitera.

Cellulose yakuwe mubikoresho. Hitamo umukozi ukwiye uhagaze, kandi ukoreshe selile yakuweho kugirango usimbuze ipamba kugirango habeho gutahura kandi ihindurwa gutegura fibre.

Vitamin ether. Ether yateguye Ether yateguye gucapa irangi rya dose, hanyuma hagereranywa nicapiro ryagereranijwe no kumenya byinshi

Abahanga ba selile bazira gucapa.

Mbere ya byose, ubushakashatsi bwiyi ngingo bwakemuye ikibazo cyo kongera gukoresha no kwanduza ibidukikije byo guta imyanda mbisi ku rugero runaka.

Muri icyo gihe, inzira nshya yongewe ku nkomoko ya selile. Icya kabiri, sodium yuburozi bwa sodium ya chlorotate na 2-chloroethanol ikoreshwa nkabakozi bakurikiraho,

Aho kuba uburozi cyane bwa acide

Ubushakashatsi ku basimbuye bufite urwego runaka rwo kuyobora, kandi rufite akamaro gakomeye gakomeye hamwe n'agaciro kerekana.

1.4.2 Ibikorwa byubushakashatsi

1.4.2.1 Kuvugurura selile mubikoresho bibisi

Ubwa mbere, ibice byibikoresho bibisi bipimirwa no gusesengurwa, hamwe nibikoresho bitatu bihagarariye byatoranijwe kugirango bakureho fibre.

Vitamine. Noneho, inzira yo gukuramo selile yari ifite agaciro nubuvuzi bwuzuye bwa alkali na aside. Hanyuma, UV

Kwinjiza ibiciro, FTRIR na XDRD byakoreshejwe muguhuza ibicuruzwa.

1.4.2 Gutegura abakora selile

Ukoresheje ibiti bya pine selile, byateguwe na alkali byibanze, hanyuma ubushakashatsi bwa orthogonal kandi bugeragezwa rimwe na kimwe byakoreshejwe,

Inzira yo kwitegura CMC, Hec na Hecmc bariteguye.

Abatangabutegetsi bateguwe na selile baranzwe na FTIR, H-NMR na Xrd.

1.4.2.3 Gusaba selile ether paste

Ubwoko butatu bwa enerebili na sodium alginate yakoreshejwe nka paste yumwimerere, hamwe nigipimo cyo gushinga cya paste, ubushobozi bwo gufata amazi no guhuza imiti byageragejwe.

Imitungo yibanze ya paste enye zumwimerere zagereranijwe no kubahiriza imitungo nububiko.

Ukoresheje ubwoko butatu bwa elegiteri na sodium alginate nka paste yumwimerere, igena ibara ryanditse paste, kora icapiro rya dose

Kugereranya bitatuAbahanga muri Celefonina

Imitungo yo gucapa ya sodium alginate.

1.4.3 Ingingo zo Guhanga udushya z'ubushakashatsi

.

Inzira nshya, kandi icyarimwe, ku rugero runaka, ikemura ikibazo cyo kongera gukoresha imyanda ibikoresho bibisi hamwe n'umwanda w'ibidukikije; kandi itezimbere fibre

Uburyo bwo gukuramo.

.

Kanseri), nibindi. Byangiza umubiri wumuntu nibidukikije. Muri iyi mpapuro, ibidukikije bya sodium byangiza ibidukikije na 2-chloroethanol ikoreshwa nkabakozi bahorera.

Aho kuba aside chloroacetike na rolonene oxide, bahanganye na selile barateguwe. .
