HPMC n'ifu ya putty

HPMC n'ifu ya putty

1.Ni uwuhe murimo w'ingenzi wo gukoresha HPMC mu ifu yuzuye? Haba hari reaction ya chimique?

—— Igisubizo: Mu ifu yuzuye, HPMC ifite uruhare runini rwo 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. Ongeramo amazi kumashanyarazi hanyuma ukayashyira kurukuta nigisubizo cyimiti, 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.

2. Umubare wa HPMC wongeyeho ni ifu ya putty?

—— Igisubizo: Ingano ya HPMC ikoreshwa mubikorwa bifatika iratandukanye bitewe nikirere, ubushyuhe, ubwiza bwa calcium yivu yaho, amata yifu yifu n "ubuziranenge busabwa nabakiriya". Muri rusange, hagati ya kg 4 na 5 kg. Kurugero: ibyinshi byifu ya putty 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.

3. Ni ubuhe buryo bukwiye bwa HPMC mu ifu yuzuye?

—— Igisubizo: Mubisanzwe, 100.000 yuan birahagije kugirango ifu yuzuye, 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 ibishishwa birenze 100.000, ubwiza buzagira ingaruka kumazi. Ntabwo ari byinshi.

4. Kuki ifu yuzuye ifuro ifuro ifuro?

—— Igisubizo: Fenomenon: ibibyimba bitangwa mugihe cyubwubatsi kandi nyuma yigihe runaka, ubuso bwa putty burabyimbye.

impamvu:

1. Urufatiro rurakabije kandi umuvuduko wo guhomesha urihuta cyane;

2. Igice cya putty mubwubatsi bumwe ni kinini cyane, kirenze 2.0mm;

3. Ibirungo biri mu nzego z'ibanze ni byinshi cyane, kandi ubucucike ni bunini cyane cyangwa buto cyane.

4. Nyuma yigihe cyubwubatsi, guturika no kubira ifuro hejuru biterwa ahanini no kuvanga kutaringaniye, mugihe HPMC igira uruhare mukubungabunga amazi, kubyimba no kunoza imikorere mumashanyarazi ya putty, kandi ntigira uruhare mubitekerezo.

5. Niyihe mpamvu yo gukuraho ifu yo gukuramo ifu yuzuye?

—— Igisubizo: Ibi bifitanye isano ahanini nubunini nubwiza bwa calcium ya calcium yongeyeho. Kalisiyumu nkeya ya calcium yumukara hamwe nigipimo kidakwiye cya CaO na Ca (OH) 2 muri calcium yumukara bizatera gukuramo ifu. Igihe kimwe, bifitanye isano na HPMC. Igipimo cyo gufata amazi ni gito, kandi ivu rya calcium ya calcium ihagije ntabwo ihagije, nayo izatera kuvanaho ifu.

6. Kuki gushyiramo uburemere murwego rwo gusiba?

—— Igisubizo: Muri iki gihe, ubwiza bwa selile ikoreshwa muri rusange ni hejuru cyane. Bamwe mubakora bakoresha 200.000 selile kugirango bakore putty. Ibishishwa byakozwe murubu buryo bifite ubukonje bwinshi, bityo bikumva biremereye mugihe cyo gusiba. Ingano isabwa yifu ya putty kurukuta rwimbere ni kg 3-5, naho viscosity ni 80.000-100.000.
