Gukoresha ubumenyi bwa hydroxypropyl methylcellulose mumashanyarazi

Ingano ya HPMC ikoreshwa mubikorwa bifatika iratandukanye bitewe nikirere, ubushyuhe, ubwiza bwifu ya calcium yivu yaho, amata yifu yifu n "ubuziranenge busabwa nabakiriya".Muri rusange, ni hagati ya 4 kg 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.

Ni ubuhe buryo bukwiye bwa hydroxypropyl methylcellulose (HPMC) kugirango habeho ifu ya putty?

Ifu ya putty muri rusange ni 100.000 Yuan, 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 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.

Nibihe bikorwa nyamukuru byo gukoresha HPMC muri poro ya putty?

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

Kubyimba: Cellulose irashobora kubyimba kugirango ihagarike kandi igumane igisubizo 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 nkeya, CaO H2O = Ca (OH) 2 - Ca (OH) 2 CO2 = CaCO3 ↓ H2O Uruhare rwa calcium yivu muri CO2 mu mazi no mu kirere Muri ubu buryo, karubone ya calcium ikorwa, mu gihe HPMC igumana amazi gusa, igafasha gufata neza calcium ya ivu, kandi ntabwo yitabira ikintu icyo ari cyo cyose ubwacyo.
