Ibyiciro nibiranga urwego rwubwubatsi

. Nyuma yuruhererekane rwibisubizo, imiti ya selile irakorwa. Mubisanzwe, urwego rwo gusimbuza ni 1.6 ~ 2.0, kandi urwego rwo gusimbuza buratandukanye. Ni iya Not-ionic selile.

1. Methylcellsellllse irashonga mumazi akonje, amazi ashyushye azahura ningorane, kandi ph urwego rwibisubizo bihamye biri hagati ya 3/12. Ibicara, Guar gum hamwe nibindi byinshi byibasiwe birahuye cyane. Gelasiyo ibaho iyo ubushyuhe bugera ku bushyuhe bwa gelale.

Kugumana amazi ya methylcellseliulose biterwa n'amafaranga yongeweho, viscosiya, ubunebwe hamwe nubutaka. Muri rusange, nto, viso ndende, ifungwa ry'amazi menshi. Muri bo, kugumana amazi bifite ingaruka zikomeye, kandi urwego rwa vinosi ntabwo ruringaniye mu buryo butaziguye no kugumana amazi. Igipimo cyo gusebanya cyane cyane giterwa nurwego rwo guhindura ubuso bwa selile duce hamwe nibyiza byibice. Muri erebire yavuzwe haruguru, Methyl selile na hydroxypropyl methyl Methilose ifite igumana ryinshi.

Impinduka zubushyuhe zirashobora kugira ingaruka zikomeye kugumana amazi ya methyl selile. - hejuru yubushyuhe, kubangamira amazi. Niba ubushyuhe bwa minisiteri burenze 40 ° C, ugumana amazi ya methyl selile bizagabanuka cyane, bigira ingaruka zikomeye kubakwa kuri minisiteri.

Methylcellse ifite ingaruka zikomeye ku gikorwa no guhindura minisiteri. "Urukuta" hano rwerekeza ku mahigo hagati y'ibikoresho by'umukozi n'urukuta, ni ukuvuga ko kurwanya minisiteri. Imbaraga zo guswera, imbaraga za mirtar, kandi imbaraga zisabwa nabakozi mukoresha nazo nini nini, kandi iyubakwa rya minisiteri ntabwo ari ryiza. Methycellse yubahirije urwego ruciriritse mu bicuruzwa bya selile.

2. HydroxyPropyl Methylcellsellse (HPMC) [C 6 h 7 o 2 (OH) 4-OHT) NETHYL THWERUPOYL Methyl Methyl Methyl Methyl yiyongereye vuba. Ni selile itari ionic ivanze ether yateguwe nuruhererekane rwibisubizo nyuma ya alkali, aho profloride okiside na methyl bakoreshwa nkabakozi bashya. Urwego rwo gusimbuza ni 1.2 / 2.0. Imitungo yayo iratandukanye ukurikije igipimo cya uburyo na hydroxyPropyle.

1.. HydroxyPropyl methylcellse igabanijwemo ubwoko bwa hot-gushonga nubwoko bwihuse. Ubushyuhe bwa pelale mumazi ashyushye burenze ibyuma bya methylcellse. Irerekana kandi iterambere ryinshi kuri methycellsellse mugihe yashonga mumazi akonje.

Uruzinduko rwa hydroxyPropyl methylcellse ifitanye isano n'uburemere bwa molekile, kandi uburemere bwa molekiri ni bwinshi. Ubushyuhe bugira ingaruka kandi ku rubyiruko, uko ubushyuhe bwiyongera, vicosity igabanuka. Ariko, ingaruka zubushyuhe kuri viscosity iri munsi yubwa methyl selile. Igisubizo ni ububiko buhamye mubushyuhe bwicyumba.

3. Kugumana amazi ya hydroxyPropyl methylcellellse biterwa namafaranga yiyongera, vino, kandi igipimo cyo kugumana amazi hejuru ya methyl selile.

4. HydroxyPropyl Methylcellllse irahamye acide na alkali, kandi igisubizo cyacyo gihamye muri PH tsinda ya 2/12. Imikorere ya soda ya Caustic na Lime ntabwo ifite uruhare runini, ariko alkali irashobora kwihutisha igipimo cyimiseke, kandi uruzinduko rwiyongera. HydroxyPropyl Methylcellse ihamye muminyuhuri isanzwe, ariko mugihe ibitekerezo byumunyu bisumba, viscosity ya hydroxyProppopyl methylcellse igisubizo gikunda kwiyongera.

HydroxyPropyl MethylcellllAse irashobora kuvangwa n'amazi yo gushonga amazi kugirango akore igisubizo kimwe, kinini. Nka Polyvinyl Inzoga, ibikatsi bya Ether, gum yimboga, nibindi

HydroxyPropyl methylcellse ifite enzyme nziza kuruta methylcelllllcelllmethylmethylmethylmethylmethylmethylcellse kurenza iya Methylcellse. Shingiro.

Batatu, hydroxyAythyl selile (HEC) ikozwe mu ipamba yatunganijwe yavuwe na Alkali, imbere ya Acetone, na Etylene okiside ibaho. Impamyabumenyi yacyo ni 1.5 / 2.0. Ifite hydrofilire ikomeye kandi biroroshye gukuramo ubushuhe.

1. Hydroxyyethyl selile irashonje mumazi akonje, ariko biragoye gusesa mumazi ashyushye. Igisubizo kirahagaze ku bushyuhe bwinshi kandi ntabwo gifite ganede. Irashobora gukoreshwa igihe kirekire mumahoro yubushyuhe bwinshi, ariko ugusuka amazi biri hasi kurenza ibya methyl selile.

2. Hydroxyyethyl selile irahamye aside rusange na alkali. Alkali yihutiye gusenya, kandi ubukuru bwayo bwiyongera gato. Gutandukana kwayo mumazi birababaje gato kurenza ibya methyl selile na hydroxyPropyl methyl Methielose.

3. HydroxyAythyl Cellulose afite imikorere myiza yo kurwanya minisiteri, ariko igihe kirekire, hari hydroxyithyl yatunganijwe neza kuruta imikorere minini ya methyl n'ibirimo byinshi.

4.. Urwego rwo gusimbuza ni 0.4 / 1.4, kandi urwego rwo gusimburwa rufite ingaruka zikomeye kumikorere.

Carboxymethyl selile ifite hygroscopique nyinshi, nububiko rusange burimo amazi menshi.

2..

Ikirangantego cyacyo cyibasiwe cyane na PH. Mubisanzwe bikoreshwa kuri minisiteri ya Gypsum, ntabwo ari sima. Ku bijyanye na alkalinity ndende, izatakaza urusyo.

Kugumana amazi ari munsi yubwa methyl selile. Mypsum Mortar ifite ingaruka zidindiza, kugabanya imbaraga. Ariko igiciro cya carboxymethyl selile irari munsi cyane kurenza iya methyl selilese.
