Imikorere ya hydroxypropyl methylcellulose (HPMC) murukuta
1.Ni ibihe bintu nyamukuru byerekana tekinike ya hydroxypropyl methylcellulose (HPMC)?
Hydroxypropyl ibirimo hamwe nubwiza, abakoresha benshi bahangayikishijwe nibi bipimo byombi. Abafite hydroxypropyl nyinshi muri rusange bafite amazi meza. Iyifite ubukonje bwinshi ifite gufata neza amazi, ugereranije (ntabwo rwose), naho iyifite ubukonje bwinshi ikoreshwa neza mumabuye ya sima.
2.Ni uwuhe murimo w'ingenzi wo gukoresha HPMC mu ifu yuzuye?
Ifu yuzuye, HPMC ifite imirimo itatu yo 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.
3. Haba hari isano hagati yigitonyanga cyifu ya HPMC?
Gutakaza ifu yifu ya putty bifitanye isano ahanini nubwiza bwa calcium yivu, kandi ntaho bihuriye na HPMC. Kalisiyumu yuzuye ya calcium yumukara hamwe nikigereranyo cya CaO na Ca (OH) 2 muri calcium yumukara ntibikwiye, bizatera gutakaza ifu. Niba bifite aho bihuriye na HPMC, noneho gufata amazi mabi ya HPMC nabyo bizatera gutakaza ifu.
4. Umubare wahydroxypropyl methylcellulose (HPMC) murukutaifu?
Ingano ya HPMC ikoreshwa mubikorwa bifatika iratandukanye bitewe nikirere, ubushyuhe, ubwiza bwa calcium y ivu ryaho, amata yifu yifu n "ubuziranenge busabwa nabakiriya". Muri rusange, hagati ya kg 4 na 5 kg. Kurugero: ibyinshi mubifu byamavuta i Beijing ni kg 5; ifu ya putty muri Guizhou ni kg 5 mu cyi na 4.5 kg mu gihe cy'itumba; ingano ya putty muri Yunnan ni nto, mubisanzwe kg 3 kugeza kg 4, nibindi.
5. Ni ubuhe buryo bukwiye bwa hydroxypropyl methylcellulose (HPMC)?
Mubisanzwe, 100.000 Yuan yifu ya putty irahagije, kandi 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 ubwiza buri hasi (70.000-80,000), birashoboka. Birumvikana ko hejuru yubukonje, niko gufata amazi ugereranije. Iyo ibishishwa birenze 100.000, ibishishwa nta ngaruka bigira ku kubika amazi. binini.
6. Nigute ushobora guhitamo hydroxypropyl methylcellulose (HPMC) kubwimpamvu zitandukanye?
Gukoresha ifu ya putty: ibisabwa ni bike, viscosity ni 100.000, birahagije, icyangombwa nukubungabunga amazi neza. Porogaramu ya Mortar: ibisabwa cyane, ubukonje bwinshi, 150.000 nibyiza, gusaba kole: ibicuruzwa byihuse birasabwa, ubwiza bwinshi.
7. Gukoresha HPMC mu ifu yuzuye, niyihe mpamvu itera ibibyimba mu ifu yuzuye?
Ifu yuzuye, HPMC ifite uruhare runini rwo kubyimba, gufata amazi no kubaka. Ntukagire uruhare mubitekerezo byose. Impamvu zitera ibibyimba:
(1) Shira amazi menshi.
(2) Igice cyo hasi ntabwo cyumye, kandi ikindi gice cyashizwe hejuru, kandi biroroshye kubira ifuro.
