Ni ubuhe buryo bwo gushonga bwa hydroxypropyl methylcellulose HPMC?

1. Ni ubuhe buryo bwo gushonga bwa hydroxypropyl methylcellulose HPMC?

Igisubizo: Uburyo bwo gushonga mu mazi ashyushye: Kubera ko HPMC idashonga mu mazi ashyushye, HPMC ishobora gushonga neza mu mazi ashyushye mu ntangiriro, hanyuma igashonga vuba iyo ikonje. Uburyo bubiri busanzwe busobanurwa butya:

1), ongeramo 1/3 cyangwa 2/3 by'amazi akenewe mu gikoresho, hanyuma ushyushye kugeza kuri 70°C, unyanyagize HPMC ukurikije uburyo bwa 1), hanyuma utegure amazi ashyushye; hanyuma ongeramo andi mazi akonje ku mazi ashyushye, uruvange rugakonjeshwa nyuma yo kuvanga.

Uburyo bwo kuvanga ifu: Vanga ifu ya HPMC n'ibindi bintu byinshi birimo ifu, uvange neza ukoresheje icyuma gishongesha, hanyuma wongeremo amazi kugira ngo ishonge, hanyuma HPMC ishobora gushonga muri iki gihe nta guhurirana, kuko hari HPMC nkeya muri buri mfuruka ntoya Ifu izashonga ako kanya iyo ihuye n'amazi. ——Abakora ifu ya putty na mortar bakoresha ubu buryo. [Hydroxypropyl methylcellulose (HPMC) ikoreshwa nk'ikintu gikomeza ubukonje no kubika amazi muri mortar ya putty.

2) Shyira amazi ashyushye akenewe mu gikoresho hanyuma uyashyushye kugeza kuri dogere selisiyusi 70. Hydroxypropyl methylcellulose yongewemo buhoro buhoro mu kuvanga buhoro buhoro, mu ntangiriro HPMC yarerembaga hejuru y'amazi, hanyuma buhoro buhoro ikora ururenda, rukonjeshwa mu kuvanga.

2. Hari ubwoko butandukanye bwa hydroxypropyl methylcellulose HPMC. Ni irihe tandukaniro mu mikoreshereze yabyo?

Igisubizo: Hydroxypropyl methylcellulose HPMC ishobora kugabanywamo ubwoko bw'ingufu zihita n'ubwoko bw'ingufu zihita zishira. Ibikoresho by'ingufu zihita zishira vuba mu mazi akonje zikabura mu mazi. Muri iki gihe, amazi nta mvubura aba afite, kuko HPMC ikwirakwira gusa mu mazi, nta gushonga nyakuri. Hafi iminota 2, mvubura y'amazi yiyongera buhoro buhoro, igakora colloid ibonerana. Ibikoresho bishyushye, iyo bihuye n'amazi akonje, bishobora gukwirakwira vuba mu mazi ashyushye bikabura mu mazi ashyushye. Iyo ubushyuhe bugabanutse ku bushyuhe runaka, mvubura izagenda igaragara buhoro buhoro kugeza igihe ikoze colloid ibonerana. Ubwoko bw'ingufu zishyushye bushobora gukoreshwa gusa mu ifu ya putty na mortar. Muri kole y'amazi n'irangi, hazabaho ibintu byo gushyira hamwe kandi ntibishobora gukoreshwa. Ubwoko bw'ingufu zihita bukoreshwa mu buryo bwinshi. Bushobora gukoreshwa mu ifu ya putty na mortar, ndetse na kole y'amazi n'irangi, nta binyuranyo.

3. Ni iyihe mikoreshereze nyamukuru ya hydroxypropyl methylcellulose (HPMC)?

Igisubizo: HPMC ikoreshwa cyane mu bikoresho by'ubwubatsi, irangi, resins zikoze mu nganda, ibumba, ubuvuzi, ibiryo, imyenda, ubuhinzi, amavuta yo kwisiga, itabi n'izindi nganda. HPMC igabanywamo ibi bikurikira: urwego rw'ubwubatsi, urwego rw'ibiribwa n'urwego rw'imiti hakurikijwe ikoreshwa. Kuri ubu, ibicuruzwa byinshi byo mu rugo ni urwego rw'ubwubatsi. Mu rwego rw'ubwubatsi, ifu ya putty ikoreshwa ku bwinshi, hafi 90% ikoreshwa mu ifu ya putty, naho ibisigaye bikoreshwa mu ibumba rya sima na kole.

8. Ni iyihe nshingano nyamukuru yo gukoresha HPMC mu ifu ya putty, kandi se bibaho mu buryo bwa shimi?

Igisubizo: Mu ifu ya putty, HPMC igira inshingano eshatu zo gukurura, kubika amazi no kubaka. Gukomera: Selilulose ishobora gukurura kugira ngo ikomeze guhagarara neza no gukomeza gukurura, kandi irinde kugwa. Gukomera kw'amazi: gutuma ifu ya putty yumuka buhoro buhoro, kandi igafasha kalisiyumu y'ivu gukora neza iyo amazi akoze. Imiterere: Selilulose ifite ingaruka zo gusiga amavuta, bishobora gutuma ifu ya putty igira imiterere myiza. HPMC ntabwo igira uruhare mu bikorwa bya shimi, ahubwo igira uruhare rw'inyongera gusa. Kongera amazi ku ifu ya putty no kuyashyira ku rukuta ni imikorere ya shimi, kuko ibintu bishya bibaho. Iyo ukuye ifu ya putty ku rukuta, ukayisya ikameramo ifu, hanyuma ukongera kuyikoresha, ntabwo izakora kuko ibintu bishya (calcium carbonate) nabyo byakozwe. Ibice by'ingenzi bigize ifu ya kalisiyumu y'ivu ni: uruvange rwa Ca(OH)2, CaO n'ingano nto ya CaCO3, CaO+H2O=Ca(OH)2—Ca(OH)2+CO2=CaCO3↓+H2O Kalisiyumu y'ivu iri mu mazi no mu mwuka Mu gihe cya CO2, kalisiyumu karubone irakorwa, mu gihe HPMC igumana amazi gusa, igafasha mu buryo bwiza bwa kalisiyumu y'ivu, kandi ntigira uruhare mu buryo ubwo aribwo bwose.

9. HPMC ni eteri ya cellulose itari ionic, none se itari ionic ni iki?

Igisubizo: Mu magambo y’umuntu usanzwe, non-iyoni ni ikintu kidahinduka iyoni mu mazi. Iyonize yerekeza ku buryo electrolyte ivangwamo iyoni zifite umuriro zishobora kugenda mu buryo bwizewe mu kintu runaka (nk'amazi, alcohol). Urugero, sodium chloride (NaCl), umunyu turya buri munsi, irashonga mu mazi igahinduka iyoni kugira ngo ikore iyoni za sodium zigenda zimuka (Na+) zifite umuriro mwiza na iyoni za chloride (Cl) zifite umuriro mubi. Ni ukuvuga ko iyo HPMC ishyizwe mu mazi, ntabwo ihinduka iyoni zifite umuriro, ahubwo ibaho mu buryo bwa molekile.

10. Ese hari isano iri hagati y'igitonyanga cy'ifu ya putty na HPMC?

Igisubizo: Gutakaza ifu y'ifu ya putty ahanini bifitanye isano n'ubwiza bwa calcium y'ivu, kandi ntaho bihuriye na HPMC. Ingano nke ya calcium y'imvi hamwe n'ikigereranyo kidakwiye cya CaO na Ca(OH)2 muri calcium y'imvi bizatera gutakaza ifu. Niba bifitanye isano na HPMC, niba HPMC ifite amazi make, nayo izatera gutakaza ifu.
