Ubumenyi bwo gukoresha hydroxypropyl methylcellulose mu ifu ya putty

Ingano ya HPMC ikoreshwa mu bikorwa iratandukanye bitewe n'ikirere, ubushyuhe, ubwiza bw'ifu ya kalisiyumu y'ivu, formula y'ifu ya putty n' "ubwiza busabwa n'abakiriya". Muri rusange, ni hagati ya kg 4 na kg 5. Urugero: ifu nyinshi ya putty i Beijing ni kg 5; ifu nyinshi ya putty i Guizhou ni kg 5 mu mpeshyi na kg 4.5 mu gihe cy'itumba; ingano ya putty i Yunnan ni nto, muri rusange ni kg 3 kugeza kuri kg 4, nibindi.

Ni ubuhe buryo bukwiye bwo gukora ifu ya putty bwa hydroxypropyl methylcellulose (HPMC)?

Ifu ya putty muri rusange ni yuan 100.000, kandi ibisabwa kuri sitrove ni byinshi, kandi yuan 150.000 birakenewe kugira ngo byorohe kuyikoresha. Byongeye kandi, akazi k'ingenzi ka HPMC ni ukubika amazi, hagakurikiraho gucumba. Mu ifu ya putty, igihe cyose amazi abika neza kandi ubukana buri hasi (70.000-80.000), birashoboka. Birumvikana ko uko ubukana bwiyongera, ni ko amazi abika neza. Iyo ubukana burenze 100.000, ubukana buzagira ingaruka ku bukana bw'amazi. Ntabwo bikiri byinshi.

Ni iyihe nshingano nyamukuru yo gukoresha HPMC mu ifu ya putty?

Mu ifu ya putty, HPMC igira uruhare rutatu mu gutuma amazi akomera, kuyabika no kuyashyiraho.

Ububyimbirwe: Selilulose ishobora gukongerwa kugira ngo ikomeze guhagarara neza kandi ikomeze kuba imwe hejuru no hasi, kandi irinde kugwa.

Kubika amazi: tuma ifu ya putty yumuka buhoro buhoro, kandi ufashe kalisiyumu y'ivu gukora iyo amazi arimo gukora.

Imiterere: Selulosi ifite ubushobozi bwo gusiga amavuta, ibyo bikaba bishobora gutuma ifu ya putty ikora neza.

HPMC ntabwo igira uruhare mu bikorwa bya shimi, ahubwo igira uruhare rw'inyongera gusa. Kongera amazi ku ifu ya putty no kuyishyira ku rukuta ni igikorwa cya shimi, kuko ibintu bishya bibaho. Iyo ukuye ifu ya putty ku rukuta, ukayisya ikamera nk'ifu, hanyuma ukongera kuyikoresha, ntabwo izakora kuko ibintu bishya (calcium carbonate) 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 Uruhare rwa kalisiyumu y'ivu muri CO2 mu mazi no mu mwuka Muri iki kibazo, kalisiyumu karubone irakorwa, mu gihe HPMC igumana amazi gusa, igafasha mu bikorwa byiza bya kalisiyumu y'ivu, kandi ntigira uruhare mu bikorwa ibyo ari byo byose.
