Carboxymethyl TOLLECOULOSE:
Ionicselile etherikozwe muri fibre karemano (ipamba, nibindi) nyuma yo kuvura alkali, ukoresheje sodium monochlorotate nkabakozi bahorera, kandi barimo kuvura urukurikirane. Urwego rwo gusimbuza ni 0.4 ~ 1.4, kandi imikorere yacyo igira ingaruka kurwego rwo gusimburwa.
.
. Iyo ubushyuhe burenze 50 ° C, viscosity ntasubirwaho.
(3) Guhagarara kwayo byatewe cyane na PH. Mubisanzwe, irashobora gukoreshwa muri minisiteri ishingiye ku nshinge, ariko ntabwo muri minisiteri ishingiye kuri sima. Iyo alkaline nyinshi, izabura vicosity.
(4) Kugumana amazi ari munsi yubwa methyl selile. Ifite ingaruka zidindiza kuri minisiteri ishingiye kuri Gypsum kandi igabanya imbaraga. Ariko, igiciro cya carboxymethyl selile irari munsi cyane kurenza iya methyl selile.
Cellulose Alkyl Ether:
Abahagarariye ni methyl selile na Ethyl selile. Mubikorwa byinganda, chloride ya methyl cyangwa ethyl chloride isanzwe ikoreshwa nkumukozi wabuze, kandi reaction ni izi zikurikira:
Muri formula, r ahagarariye ch3 cyangwa c2h5. Kwibanda kuri Alkali ntibigira ingaruka gusa kurwego rworoshye, ariko nanone bigira ingaruka kubikoresha Alkyl Halides. Hafi ya Alkali Yibanda, Akomeye Hydrolysis ya Alkyl Halide. Kugirango ugabanye kunywa umukozi uhangayitse, kwibanda kuri Alkali bigomba kwiyongera. Ariko, iyo kwibanda kuri Alkali ari hejuru cyane, ingaruka za selile ziragabanuka, zidafasha kubyitwaramo ibintu, kandi urwego rwo guhindura rero rugabanuka. Kubwiyi ntego, yibanze kuri Lye cyangwa Lye ikomeye birashobora kongerwaho mugihe cyimyitwarire. Reaction igomba kugira igikoresho cyiza kandi cyo gutanyagura kugirango alkali ishobora kugabanywa cyane.
Methyl selile ikoreshwa cyane nka Thickener, Adhesive kandi ikingira Colloid nibindi birashobora gukoreshwa nkabasiganwa ku mbuto, ikwirakwizwa ry'imbuto, ikwirakwizwa ry'imbuto, ikwirakwizwa ry'imbuto, ikwirakwizwa ry'imbuto, ihitike, ihinduka ry'ibiyobyabwenge Ibikoresho, no gusiga irangi rya latex, icapiro yiruka, umusaruro w'ububari, kandi uvanze muri sima yakoreshejwe mu kugenzura igihe cyo gushyiraho no kongera imbaraga za mbere, n'ibindi.
Ibicuruzwa bya selile etthl bifite imbaraga nyinshi zubukanishi, guhinduka, kurwanya ubushyuhe nubukonje bukonje. Ubudodo buke bwa selilel selile irashonganye mumazi na dilute alkaline ibisubizo, nibicuruzwa byasimbuwe birashonga cyane mubintu byiza cyane. Ifite neza hamwe nibice bitandukanye na plastistizers. Irashobora gukoreshwa mugukora plastiki, firime, zirangira, ingirakamaro, ya latex hamwe nibikoresho byo gutwara ibiyobyabwenge, nibindi.
Intangiriro yamatsinda ya hydroxyalky muri selile Alkyl irashobora kunoza ibyiyumvo byayo, kugabanya ubushyuhe bwa gelation no kunoza imitungo yavuzwe haruguru iratandukanye na kamere ya asimbuye na Ikigereranyo cya Alkyl kumatsinda ya hydroxyalkyl.
Ubugari bwa Cellroxyalkl ether:
Abahagarariye ni hydroxyyerthyl selile na hydroxyPropyl selile. Abakozi bakurikiraho ni epoxides nka royoyne okiside hamwe na propaylene okiside. Koresha aside cyangwa shingiro nka catalyst. Umusaruro w'inganda nukwitwara selile ya alkali hamwe numukozi wabuze: HydroxyEthyl selile selile hamwe nimbaraga nyinshi zo gusimbuza amazi akonje namazi ashyushye. HydroxyPropyl selile hamwe nimbaraga nyinshi zo gusimbuza ni ugushonga gusa mumazi akonje ariko atari mumazi ashyushye. HydroxyAythyl selile irashobora gukoreshwa nk'ubuhunzi bwa peatings, gucapa imyenda no gusiga irangi, ibikoresho bingana n'ibikoresho, ihimbaza no kurinda inkoni. Gukoresha hydroxyPropyl selile irasa niya hydroxyyethyl selile. HydroxyPropyl Cellulose hamwe nagaciro gake cyane birashobora gukoreshwa nka farumasi ya farumasi, ishobora kugira byombi bihuza kandi bigasenyuka.
Carboxymethylcellselicese, akubise mu magambo nkCmc, muri rusange ibaho muburyo bwa sodium umunyu. Umukozi ukurikiraho ni aside monochlorocetic, kandi reaction ni izi zikurikira:
Carboxymethyl selile nizo zakoreshejwe mumazi menshi-gusoza filile. Kera, byakoreshejwe cyane cyane nko gushushanya icyondo, ariko ubu byaraguweho kugirango bikoreshwe no kongeramo ibintu byongeraga, gusiga imyenda, ibishushanyo mbonera, ibisigazwa bya carboxymethyl birashobora gukoreshwa mubiryo, imiti, kwisiga, kandi no gufatira ifumbire no kubumba.
Polyinic TOLLOULIT (PAC) ni ionicselile etherkandi ni ibintu bisoza birebiye kuri carboxymethyl selile (cmc). Ni ifu yera, iri mu ifu yumuhondo cyangwa granule, idafite uburozi, yoroshye, yoroshye mumazi itunganya neza hamwe nuburwayi bwumunyu. Nta muco wawe no kwangirika. Ifite ibiranga ubuziranenge buhanitse, urwego rwo hejuru rwo gusimbuza, no gukwirakwiza imyenda imwe. Irashobora gukoreshwa nka Binder, Thickener, Imyifatire ya Rheologiya, Ikigo cyo Guhagarika Amazi, Ibiti Polyanionic (PALC gushikama no guhaza ibisabwa byinshi.
Cyanoethyl Cellulose nigicuruzwa cya selile ya selile na acrylonike munsi ya kajuguli ya alkali:
Cyanoethyl Cellulose afite indyo yuzuye ihoraho kandi yo gutakaza hasi kandi irashobora gukoreshwa nka matrix ya resin kuri fosifore na electrouminescent. Kanoethyl yasimbuwe hasi ya kallulose irashobora gukoreshwa nkimpapuro zibuza guhindurwa.
Abatanga amavuta menshi babyibushye, ba Alkenyl, kandi inzoga zanduye za selile zateguwe, ariko ntizikoreshwa mubikorwa.
Uburyo bwo kwitegura bwa selile burashobora kugabanywamo uburyo bwo hagati bwamazi, uburyo bwo gucika intege, uburyo bwo guteka, uburyo bworoshye, uburyo bukomeye, uburyo bwihariye bwa gaze no guhuza uburyo bwavuzwe haruguru.
