Gukoresha HPMC mu ifu ya putty

1. Ni ubuhe bunini bukwiye bwa HPMC?

——Igisubizo: Muri rusange, yuan 100.000 irahagije ku ifu ya putty. Ibisabwa kuri mortier ni byinshi, kandi yuan 150.000 ni byo bikenewe kugira ngo byoroshye kuyikoresha. Byongeye kandi, akazi k'ingenzi ka HPMC ni ukubika amazi, hagakurikiraho gukuba. Mu ifu ya putty, igihe cyose amazi abika neza kandi viscosity ikaba iri hasi (70.000-80.000), birashoboka kandi. Birumvikana ko uko viscosity iba nyinshi, ni ko amazi abika neza. Iyo viscosity irenze 100.000, viscosity izagira ingaruka ku kubika amazi. Ntabwo bikiri byinshi.

2. Ni ibihe bimenyetso by'ingenzi by'ikoranabuhangaHPMC?

——Igisubizo: Ingano ya Hydroxypropyl n'ubukana, abakoresha benshi bahangayikishijwe n'ibi bimenyetso bibiri. Abafite ubukana bwinshi bwa hydroxypropyl muri rusange bafite ubukana bwiza bwo kubika amazi. Ifite ubukana bwinshi bwo kubika amazi ni nziza kurushaho, mu rugero runaka (atari rwose), naho igifite ubukana bwinshi cyo gikoreshwa neza mu gusya sima.

3. 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 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.

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

——Igisubizo: Mu magambo y’abantu basanzwe, ibintu bitari ioni ni ibintu bitazavamo iyoni mu mazi. Iyoniziyo yerekeza ku buryo electrolyte ivangwamo iyoni zifite umuriro zishobora kugenda mu buryo bwihuse mu kintu runaka (nk'amazi, alcohol). Urugero, sodium chloride (NaCl), umunyu turya buri munsi, irashonga mu mazi igatanga iyoni zigenda zimuka mu buryo bwihuse (Na+) zifite umuriro mwiza na iyoni za chloride (Cl) zifite umuriro mubi. Ni ukuvuga ko iyo HPMC ishyizwe mu mazi, ntabwo izavamo iyoni zifite umuriro, ahubwo izaba mu buryo bwa molekile.

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

——Igisubizo: Ifu itakaza ifu ya putty ifitanye isano ahanini n'ubwiza bwa calcium y'ivu, kandi ntaho ihuriye na HPMC. Ingano nke ya calcium y'imvi hamwe n'ikigereranyo kidakwiye cya CaO na Ca(OH)2 muri calcium y'imvi bizatera ifu itakaza. Niba bifitanye isano na HPMC, niba amazi ya HPMC ari make, bizanatera ifu itakaza.

6. Uburyo bwo guhitamo ikwiriyeHPMCku mpamvu zitandukanye?

——Igisubizo: Gukoresha ifu ya putty: ibisabwa ni bike, kandi viscosity ni 100.000, birahagije. Icy'ingenzi ni ugukomeza amazi neza. Gukoresha morti: ibisabwa byinshi, viscosity nyinshi, 150.000 ni byiza kurushaho. Gukoresha kole: ibikoresho byihuse bifite viscosity nyinshi birakenewe.
