Hydroxypropyl methylcellulose (HPMC) ubumenyi?

1. Intego nyamukuru ya hydroxypropyl methyl selulose (HPMC) niyihe?

HPMC ikoreshwa cyane mubikoresho byubwubatsi, gutwikira, ibisigazwa byubukorikori, ububumbyi, ubuvuzi, ibiryo, imyenda, ubuhinzi, kwisiga, itabi nizindi nganda.

HPMC irashobora kugabanywa mubyiciro byubwubatsi, ibyiciro byibiribwa nicyiciro cyubuvuzi ukurikije intego yabyo.

Kugeza ubu, ibicuruzwa byinshi byo murugo biri murwego rwo kubaka. Mu cyiciro cyubwubatsi, ifu ya putty ikoreshwa mubwinshi, hafi 90% ikoreshwa kubifu ya putty, naho ibindi bikoreshwa mumasima ya sima na kole.

2. Hariho ubwoko bwinshi bwa hydroxypropyl methyl selulose (HPMC). Ni irihe tandukaniro riri hagati yimikoreshereze yabo?

HPMC irashobora kugabanwa muburyo bwubwoko nubwoko bushushe.

Ibicuruzwa ako kanya bikwirakwira vuba mumazi akonje bikabura mumazi. Muri iki gihe, amazi ntagira ubukonje, kubera ko HPMC ikwirakwizwa mu mazi gusa kandi ntishonga. Hafi yiminota 2, ubwiza bwamazi bwiyongereye buhoro buhoro, bikora colloid ibonerana.

Ubwoko bwihuse, ubwoko bwagutse bwibisabwa, burashobora gukoreshwa mubifu ya pome na minisiteri, kimwe no mumazi ya kole hamwe n irangi.

Ibicuruzwa bishyushye, iyo bihuye namazi akonje, birashobora gukwirakwira vuba mumazi ashyushye bikabura mumazi ashyushye. Iyo ubushyuhe bugabanutse ku bushyuhe runaka, ubukonje bugaragara buhoro buhoro kugeza igihe habaye ibibyimba bisobanutse neza.

Ubwoko bushyushye burashobora gukoreshwa gusa muri poro ya pome na minisiteri.

3. Ni ubuhe buryo bwo gusesa hydroxypropyl methyl selulose (HPMC)?

Uburyo bwo gushonga amazi ashyushye: Kubera ko HPMC idashonga mumazi ashyushye, HPMC irashobora gukwirakwizwa kimwe mumazi ashyushye mugihe cyambere, hanyuma igashonga vuba iyo ikonje. Uburyo bubiri busanzwe busobanurwa gutya:

(1) Shira amazi asabwa muri kontineri hanyuma uyashyuhe kugeza kuri 70 ° C. Buhoro buhoro ongeramo hydroxypropyl methylcellulose hamwe no gukurura buhoro, tangira HPMC ireremba hejuru y’amazi, hanyuma buhoro buhoro ukora ibishishwa, hanyuma ukonje ibishishwa ukoresheje.

(2). Ongeramo 1/3 cyangwa 2/3 by'amazi asabwa muri kontineri hanyuma ubishyuhe kuri 70 ° C. Ukurikije uburyo bwavuzwe haruguru, kwirakwiza HPMC kugirango utegure amazi ashyushye; hanyuma ongeramo amazi asigaye mumazi ashyushye. Muburyo bworoshye, shyira imvange nyuma yo gukurura.

Uburyo bwo kuvanga ifu: Kuvanga ifu ya HPMC hamwe ninshi mubindi bintu byifu yifu hamwe na mixeur, hanyuma ukongeramo amazi kugirango ushonga, hanyuma HPMC irashobora gushonga muriki gihe idakomye, kuko buri mfuruka ntoya, hariho akantu gato ka HPMC Ifu izahita ishonga iyo ihuye namazi.

4. Nigute dushobora gusuzuma ubuziranenge bwa hydroxypropyl methylcellulose (HPMC) byoroshye kandi byihuse?

. Nyamara, ibyinshi mubicuruzwa byiza bifite umweru mwiza.

.

. Kurenza ukohereza, nibyiza, byerekana ko imbere bitagaragara neza.

(4) Igipimo: uko igipimo kinini, kiremereye ni cyiza. Umwihariko wo muri rusange uterwa na hydroxypropyl nyinshi irimo, kandi uko hydroxypropyl iri hejuru, niko gufata amazi neza.

5. Ni ibihe bimenyetso nyamukuru bya tekinike ya hydroxypropyl methyl selulose (HPMC)?

Hydroxypropyl ibirimo hamwe nubwiza, ibyinshi muribi bireba ibi bipimo byombi. Kugumana amazi muri rusange nibyiza kubafite hydroxypropyl nyinshi. Ubukonje bwinshi, kubika amazi, isano (aho kuba byimazeyo) nibyiza, hamwe nubwiza bwinshi, bukoreshwa neza muri sima ya sima.

6. Nibihe bikoresho nyamukuru bya hydroxypropyl methyl selulose (HPMC)?

Ibikoresho by'ibanze bya HPMC: ipamba inoze, methyl chloride, okiside ya propylene, nibindi.

7. Ni ubuhe butumwa nyamukuru bwo gukoresha hydroxypropyl methyl selulose (HPMC) mu ifu yuzuye? Haba hari reaction ya chimique?

Mu ifu yuzuye, HPMC ifite uruhare runini rwo kubyimba, gufata amazi no kubaka.

Kubyimba: Cellulose irashobora kubyimba kugirango ihagarike kandi igumane igisubizo kimwe kandi hejuru no hepfo, hamwe no kurwanya kugabanuka.

Kubika amazi: kora ifu ya putty yumye gahoro gahoro, kandi ufashe calcium yumukara gukora mugihe cyamazi.

Ubwubatsi: Cellulose igira amavuta yo kwisiga, ishobora gutuma ifu ya putty igira imikorere myiza.

HPMC ntabwo yitabira imiti iyo ari yo yose, igira uruhare runini.

8. Impumuro ya hydroxypropyl methyl selulose (HPMC) ni ubuhe?

HPMC yakozwe nuburyo bwo gukemura ikoresha toluene na isopropanol nkigisubizo. Niba idakarabye neza, izaba ifite impumuro isigaye.

9. Nigute ushobora guhitamo hydroxypropyl methylcellulose (HPMC) kubwimpamvu zitandukanye?

Gukoresha ifu ya putty: ibisabwa ni bike, viscosity ni 100.000, birahagije, icyangombwa nukugumya amazi neza.

Gukoresha minisiteri: ibisabwa byinshi, ubukonje bwinshi, 150.000 nibyiza.

Porogaramu ya kole: ibicuruzwa byihuse birasabwa, hamwe nubwiza bwinshi.

10. Gukoresha hydroxypropyl methyl selulose (HPMC) mu ifu yuzuye, niki gitera ifu ya putty kubyara ibibyimba?

Mu ifu yuzuye, HPMC ifite uruhare runini rwo kubyimba, gufata amazi no kubaka. Ntukagire uruhare mubitekerezo byose.

Impamvu zibibyimba:

1）. Shira amazi menshi.

2）. Niba igice cyo hasi kitumye, kuraho ikindi gice hejuru, bizoroha no kubira ifuro.

Ibicuruzwa byacu byamenyekanye cyane kandi byizewe nabaguzi kandi bizahaza ibyifuzo byubukungu n’imibereho byimyaka 8 byohereza ibicuruzwa mu Bushinwa Ubwubatsi Grade Cellulose HPMC Yifashishijwe Drymix Mortar HPMC, Ibintu byacu bihora bitangwa mumatsinda menshi ninganda nyinshi. Hagati aho, ibicuruzwa byacu bigurishwa muri Amerika, Ubutaliyani, Singapuru, Maleziya, Uburusiya, Polonye, ​​hiyongereyeho Uburasirazuba bwo hagati.

Imyaka 8 yohereza ibicuruzwa mu Bushinwa HPMC, Ibikoresho byubaka, Duhuza igishushanyo, gukora no kohereza hanze hamwe nabakozi barenga 100 babishoboye, sisitemu yo kugenzura ubuziranenge hamwe nikoranabuhanga rifite uburambe.Tugumana umubano wigihe kirekire mubucuruzi nabacuruzi hamwe nababigurisha bagize ibihugu birenga 50, nka Amerika, Ubwongereza, Kanada, Uburayi na Afurika n'ibindi
