Ni irihe tandukaniro riri hagati ya hydroxypropyl methyl selile na methyl selile?

1.(HPMC) Umubiri na shimi:

1. Kugaragara: MC ifite fibrous yera cyangwa ifu ya granular cyangwa granular, impumuro.

2. Ibyiza: MC hafi idasobanutse muri ethanol yuzuye, ether na acetone. Gukwirakwiza vuba no kubyimba mumazi ashyushye kuri 80 ~ 90 ° C, kandi ushonga vuba nyuma yo gukonja. Igisubizo cya akeque kirahagaze neza mubushyuhe bwicyumba, kandi gishobora gufata ubushyuhe bwinshi, kandi gel irashobora guhinduka hamwe nigisubizo cyubushyuhe. Ifite ubuvuzi buhebuje, itatatana, kugendera, kubyimba, gusumba, kugumana amazi hamwe numutungo wa firime, hamwe namavuta. Filime yashinzwe ifite uburwayi buhebuje, guhinduka no gukorera mu mucyo. Kuberako ntabwo ari ionic, birashobora guhuza nabandi ebyesiers, ariko biroroshye kumunyu, kandi igisubizo kirahagaze murwego rwa PH2-12.

3. Ubucucike bugaragara: 0.30-0.70g / cm³, ubucucike kuri 1.3g / cm³.

2. Uburyo budahungabanya:

Iyo ibicuruzwa MC byongewe mumazi, bazatera ubwoba hanyuma barashonga, ariko iseswa riratinda cyane kandi rigoye. Hariho uburyo butatu bwibitekerezo bukurikira, kandi abakoresha barashobora guhitamo uburyo bworoshye ukurikije imikoreshereze yabo:

1. Uburyo bwamazi ashyushye: Kubera ko MC idashonga mumazi ashyushye, MC irashobora gutatanya mumazi ashyushye mugihe cyambere, hanyuma iyo bikonje, uburyo bubiri busanzwe busobanurwa ngo:

1). Shira umubare ukenewe wamazi ashyushye muri kontineri no gushyuha kugeza kuri 70 ° C. MC yongeyeho buhoro buhoro kubyutsa gahoro, ibanza MC yareremba hejuru y'amazi, hanyuma ikaba yaratembaga buhoro buhoro, yakonje yadutse.

2). Ongeramo 1/3 cyangwa 2/3 by'amazi asabwa muri kontineri, kandi ubushyure kuri 70 ° C. Ukurikije uburyo bwa 1), gutatanya MC gutegura amazi ashyushye; Noneho ongeramo umubare usigaye wamazi akonje cyangwa amazi ya barafu kugirango usuzugure amazi ashyushye, imvange yarakonje nyuma yo gukangura.

2. Uburyo bwo kuvanga powder: Ifu ya MC Ibice bingana cyangwa byinshi byibintu byatatanye byuzuye no kuvanga byumye, hanyuma mpumeke mumazi, noneho MC irashobora gushonga muri iki gihe nta mubabaro.

3. Uburyo bworoshye bworoshye: Gutatana cyangwa gutose mc hamwe na erhanol glycol cyangwa etylene glycol cyangwa amavuta, hanyuma wongere amazi kugirango ashongesheje neza muri iki gihe.

3. GUKORESHA:

Iki gicuruzwa gikoreshwa cyane mu kubaka inyubako, ibikoresho byo kubaka, amasasu adahitanye, ipaki, inka, ibibyimba, ibibyimba, ibibindi, ibibari bigumaho amazi, nkabakiriya bashinzwe amazi mubikoresho byo kubaka, nkumukozi wa firime Kandi ubyimbye mu nganda zo gupfuka, kandi nacyo ikoreshwa cyane mugutegura peteroli n'imiti ya buri munsi.

Methycellsellse (MC) kumubiri no mumiti:

1. Kugaragara: MC ifite fibrous yera cyangwa ifu ya granular cyangwa granular, impumuro.

2. Ibyiza: MC hafi idasobanutse muri ethanol yuzuye, ether na acetone. Gukwirakwiza vuba no kubyimba mumazi ashyushye kuri 80 ~ 90> ℃, kandi arashonga vuba nyuma yo gukonja. Igisubizo cya akeque kirahagaze neza mubushyuhe bwicyumba, kandi gishobora gufata ubushyuhe bwinshi, kandi gel irashobora guhinduka hamwe nigisubizo cyubushyuhe. Ifite ubuvuzi buhebuje, itatatana, kugendera, kubyimba, gusumba, kugumana amazi hamwe numutungo wa firime, hamwe namavuta. Filime yashinzwe ifite uburwayi buhebuje, guhinduka no gukorera mu mucyo. Kuberako ntabwo ari ionic, birashobora guhuza nabandi ebyesiers, ariko biroroshye kumunyu, kandi igisubizo kirahagaze murwego rwa PH2-12.

3. Ubucucike bugaragara: 0.30-0.70g / cm³, ubucucike kuri 1.3g / cm³.

4. Uburyo budahungabanya:

MC> Iyo ibicuruzwa byongewe mumazi, bizatera hanyuma bishonga, ariko ibyuma biratinda cyane kandi biragoye. Hariho uburyo butatu bwibitekerezo bukurikira, kandi abakoresha barashobora guhitamo uburyo bworoshye ukurikije imikoreshereze yabo:

1. Uburyo bwamazi ashyushye: Kubera ko MC idashonga mumazi ashyushye, MC irashobora gutatanya mumazi ashyushye mugihe cyambere, hanyuma iyo bikonje, uburyo bubiri busanzwe busobanurwa ngo:

1). Shira umubare ukenewe wamazi ashyushye muri kontineri no gushyuha kugeza kuri 70 ° C. MC yongeyeho buhoro buhoro kubyutsa gahoro, ibanza MC yareremba hejuru y'amazi, hanyuma ikaba yaratembaga buhoro buhoro, yakonje yadutse.

2). Ongeramo 1/3 cyangwa 2/3 by'amazi asabwa muri kontineri, kandi ubushyure kuri 70 ° C. Ukurikije uburyo bwa 1), gutatanya MC gutegura amazi ashyushye; Noneho ongeramo umubare usigaye wamazi akonje cyangwa amazi ya barafu kugirango usuzugure amazi ashyushye, imvange yarakonje nyuma yo gukangura.

2. Uburyo bwo kuvanga powder: Ifu ya MC Ibice bingana cyangwa byinshi byibintu byatatanye byuzuye no kuvanga byumye, hanyuma mpumeke mumazi, noneho MC irashobora gushonga muri iki gihe nta mubabaro.

3. Uburyo bworoshye bworoshye: Gutatana cyangwa gutose mc hamwe na erhanol glycol cyangwa etylene glycol cyangwa amavuta, hanyuma wongere amazi kugirango ashongesheje neza muri iki gihe.

5. GUKORESHA:

Iki gicuruzwa gikoreshwa cyane mu kubaka inyubako, ibikoresho byo kubaka, amasasu adahitanye, ipaki, inka, ibibyimba, ibibyimba, ibibindi, ibibari bigumaho amazi, nkabakiriya bashinzwe amazi mubikoresho byo kubaka, nkumukozi wa firime Kandi ubyimbye mu nganda zo gupfuka, kandi nacyo ikoreshwa cyane mugutegura peteroli n'imiti ya buri munsi.
