Sobanukirwa imitungo ya hydroxyproppopyl methylcellse (HPMC) mubwubatsi

HydroxyPropyl MethylcellAlose (HPMC) irakoreshwa cyane mubwubatsi kubera imitungo yayo myinshi. Kubaka byubwubatsi bigira uruhare runini muburyo butandukanye, harimo hasi, amabati, igipfukisho cyanyuma no kwishishoza. Ibi bifatika bigomba kugira imitungo runaka, nkayo ​​ikomeye, ibikorwa byiza no kuramba, kwemeza ko ihuza ryizewe mubintu bitandukanye byubwubatsi. HydroxyPropyl MethylcellALese (HPMC) nimwe mu nzoga zingenzi mugutegura ibanga ryubwubatsi. Ibintu byabo byihariye byongera cyane imikorere no guhinduranya ibyo bifatika.

1.Gira imiterere ya HPMC
HydroxyPropylmethylcellcellcellCellse (HPMC) ni polymer-synthique polymer ikomoka kuri selile. Ikozwe nu kuvura selile hamwe na alkali hanyuma ukinjizamo imyanda ya propalene kugirango itangire amatsinda ya hydroxyPropyle. Nyuma yaho, methyl chloride yakoreshejwe mu kumenyekanisha amatsinda ya Methyl, bityo agakora imiterere hamwe na hydroxyproppopyl (-ch2chohch3) na methyl (-ch3) abasimbuye kuri selile. Iyi miterere yimiti iha Hpmc imitungo itandukanye, bigatuma bikwiranye nuburyo butandukanye.

2.Inshingano za HPMC mumyitozo ngororamubiri
HPMC ikora imirimo itandukanye mubwubatsi. Ubwa mbere, ikora nka romologiya imyuka, kugenzura viscosity hamwe nimyitwarire yo kumeneka. Icya kabiri, itezimbere itunganijwe mukurinda gutandukana no gutura ahantu hakomeye muri binder kuvanga. Icya gatatu, HPMC izamura imitungo ifatika yo kumukora kandi iteza imbere ubumwe bukomeye hagati yimyitozo na substrate. Byongeye kandi, bifasha kwagura igihe cyo gufungura hamwe nubuzima bwinkono yo kugendera, kwemerera umwanya uhagije wo gusaba no guhinduka mbere yo gutangaza.

3.Imitungo nyamukuru ya HPMC mubwubatsi

3.1 Gufungwa Amazi
Kimwe mu bintu by'ingenzi bya HPMC mubwubatsi nubushobozi bwayo bwo kugumana amazi. HPMC Molecules ikora imiterere yumurongo mubisobanuro bya Matrix, umutego wamazi molekile binyuze muri hydrogen. Ubu bushobozi bwo gukora amazi bufasha kurangiza hydration yibice bigize gucikamo ibice, biteza imbere gukiza no kwiyongera kwubatsi. Kugumana amazi ahagije ni ngombwa, cyane cyane muburyo buke bwayo cyangwa mugihe cyigihe kirekire cyo gukira, kugirango birebe imikorere idahwitse.

3.2 kubyimbye
HPMC ikora nkumubyimba mubwubatsi, atanga vicosity kandi ituze mu mikorere. Kuba hari amatsinda ya hydroxyle na methyl kuri selile ya selile yemerera molekile ya HPMC ikorana na molekile yamazi hanyuma ugakora imiterere ya sul. Iyi mvugo yijimye yateje imbere SAG irwanya SAG nibikoresho bitatonyanga, byoroha gusaba hejuru yubushyuhe butanyerera cyangwa ikora. Kugenzura vicosity yo kumeza ni ngombwa kugirango ugere ku kugera ku buryo bukwiye no guhuriza hamwe mugihe cyo gusaba.

3.3
HPMC yongerera ibintu byo guhuza imigabane yubwubatsi mugutezimbere imikoranire yububabare hagati yimyitozo nubutaka. Kubaho kw'amatsinda ya hydroxyle na methyl kuri molekile ya HPMC yemerera gukora ingwate za hydrogen hamwe na subgesrate zitandukanye, harimo n'ibasire, beto, ceralics. Kugera ku buhungiro bukomeye hamwe n'imbaraga nyinshi ndetse no mubihe bitoroshye nko kwishyurwa cyane cyangwa guhindagurika k'ubushyuhe. Guhitamo Uburemere bwa HPMC burashobora kuzamura ibintu bifatika.

3.4 Gushiraho firime
Usibye uruhare rwayo muguhuza ibigo, HPMC ifasha gukora firime ikomeza ku buso bwa substrate. Mugihe cyumye kandi gikizana, molekile ya HPMC irahuza kandi yizirikamo, ikora film yo guhuriza hamwe igaburira ibihuha hamwe nukurikiza substrate. Filime ikora nk'inzitizi, irinda ingufu mu bintu biterwa ibidukikije nk'ubushuhe, ubushyuhe n'ubushishozi. Byongeye kandi, imiterere ya firime ya HPMC ifasha kunoza ibintu bifatika no kurwanya ikirere.

4. Ingaruka za HPMC ku mitungo ifatika ni romantique
Ongeraho HPMC yo kubaka ibifungo birashobora kugira ingaruka zikomeye kubiranga imikorere. Guhitamo neza amanota ya HPMC, kwibanda hamwe nibipimo byo kwibandaho nibyingenzi kugirango ugere kubintu bifatika kandi byubahiriza ibisabwa. Byinshi Hpmc irashobora kuvamo kubyimba cyane no kugabanya imbaraga zo gutwika, mugihe ibintu bidahagije bya HPMC bishobora kuvamo ibikorwa bibi no guhuza bidahagije. Kubwibyo, uburyo bwo kwemeza no kwipimisha ni ngombwa kugirango buringanire imitungo itandukanye ya HPMC kandi igagera ku mikorere myiza yo guhuza.

HydroxyPropyl MethylcellllAlose (HPMC) ifite uruhare runini mugutezimbere imikorere no guhinduranya ibifatika byubwubatsi. Umutungo wacyo wihariye, harimo no kugumana amazi, kubyimba, gusohora no gukora siporo, bifasha kunoza imikorere rusange no kuramba byo gufatirwa muburyo butandukanye bwo kubaka. Mugusobanukirwa numuntu wingenzi wa HPMC ningaruka zabyo kumyitozo ngororamubiri, abamushinyagurira barashobora guhitamo uburyo bwo gufata ibyemezo kugirango bahuze ibisabwa byihariye kandi bizemeza ko guhuza byizewe mubintu bitandukanye byubwubatsi.
