Gukoresha HPMC mu ifu yuzuye

1. Ni ubuhe buryo bukwiye bwa HPMC?

—— Igisubizo: Mubisanzwe, 100.000 yuan birahagije kubifu. Ibisabwa kuri minisiteri ni byinshi, kandi 150.000 yuan birakenewe kugirango bikoreshwe byoroshye. Byongeye kandi, umurimo wingenzi wa HPMC nukubika amazi, ugakurikirwa no kubyimba. Mu ifu ya putty, mugihe cyose gufata amazi ari byiza kandi ibishishwa bikaba bike (70.000-80,000), birashoboka. Birumvikana ko hejuru yubukonje, niko gufata amazi ugereranije. Iyo ubwiza burenze 100.000, ubwiza buzagira ingaruka kumazi. Ntabwo ari byinshi.

2. Ni ibihe bimenyetso nyamukuru bya tekinike yaHPMC?

—— Igisubizo: Hydroxypropyl ibirimo hamwe nubwiza, abakoresha benshi bahangayikishijwe nibi bipimo byombi. Abafite hydroxypropyl nyinshi muri rusange bafite amazi meza. Iyifite ubukonje bwinshi ifite amazi meza, ugereranije (ntabwo rwose), naho iyifite ubukana bwinshi ikoreshwa neza muri sima ya sima.

3. Ni ubuhe butumwa nyamukuru bwo gukoresha HPMC mu ifu yuzuye, kandi bibaho muburyo bwa shimi?

—— Igisubizo: Mu ifu yuzuye, HPMC ifite inshingano eshatu zo kubyimba, gufata amazi no kubaka. Kubyimba: Cellulose irashobora kubyimba kugirango ihagarike kandi igumane igisubizo kimwe hejuru no hepfo, kandi irwanya kugabanuka. Kubika amazi: kora ifu ya putty yumye gahoro gahoro, kandi ufashe calcium yivu gukora mugihe cyamazi. Ubwubatsi: Cellulose ifite amavuta yo gusiga, ashobora gutuma ifu ya putty yubaka neza. HPMC ntabwo yitabira imiti iyo ari yo yose, ariko igira uruhare gusa. Kongeramo amazi kumashanyarazi no kuyashyira kurukuta ni reaction ya chimique, kuko havutse ibintu bishya. Niba ukuyemo ifu ya putty kurukuta kurukuta, ukayisya ifu, ukongera ukayikoresha, ntabwo bizakora kuko havutse ibintu bishya (calcium karubone). ) na. Ibice byingenzi bigize ifu ya calcium yivu ni: imvange ya Ca (OH) 2, CaO hamwe na CaCO3, CaO + H2O = Ca (OH) 2 —Ca (OH) 2 + CO2 = CaCO3 ↓ + H2O Kalisiyumu yivu iri mumazi numwuka Mubikorwa bya CO2, karubone ya calcium ikora, mugihe HPMC igumana amazi gusa, ikagira uruhare mukwitabira ivu.

4. HPMC ni selile ya ionic selile, nonese non-ionic niki?

—— Igisubizo: Mu magambo y’abalayiki, non-ion ni ibintu bitazaba ioni mumazi. Ionisation bivuga inzira electrolyte igabanyijemo ion zishishwa zishobora kugenda mubwisanzure mumashanyarazi yihariye (nk'amazi, inzoga). Kurugero, sodium chloride (NaCl), umunyu turya burimunsi, ushonga mumazi na ionize kugirango ubyare sodium yimuka yimuka kubuntu (Na +) byuzuye neza na ioni ya chloride (Cl) byashizwemo nabi. Nukuvuga ko, iyo HPMC ishyizwe mumazi, ntabwo izitandukanya na ion zashizwemo, ahubwo ibaho muburyo bwa molekile.

5. Haba hari isano hagati yigitonyanga cyifu ya HPMC?

—— Igisubizo: Gutakaza ifu yifu ya putty bifitanye isano ahanini nubwiza bwa calcium yivu, kandi ntaho bihuriye na HPMC. Kalisiyumu nkeya ya calcium yumukara hamwe nigipimo kidakwiye cya CaO na Ca (OH) 2 muri calcium yumukara bizatera gutakaza ifu. Niba bifite aho bihuriye na HPMC, noneho niba amazi ya HPMC ari mabi, bizatera no gutakaza ifu

6. Nigute wahitamo igikwiyeHPMCku mpamvu zitandukanye?

—— Igisubizo: Gukoresha ifu ya putty: ibisabwa ni bike, kandi ibishishwa ni 100.000, birahagije. Icyangombwa nukubungabunga amazi neza. Gukoresha minisiteri: ibisabwa hejuru, viscosity nyinshi, 150.000 nibyiza. Gukoresha kole: ibicuruzwa byihuse hamwe nubwiza bwinshi birasabwa.
