Ni ubuhe buryo bukwiye bwa hydroxypropyl methylcellulose (HPMC)?
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 ibishishwa birenze 100.000, ubwiza buzagira ingaruka kumazi. Ntabwo ari byinshi.
Nubuhe buryo bwo gusesa hydroxypropyl methylcellulose (HPMC)?
. Nyamara, ibyinshi mubicuruzwa byiza bifite umweru mwiza.
(2) Ubwiza: Ubwiza bwa HPMC mubusanzwe bufite mesh 80 na mesh 100, naho mesh 120 ni mike. HPMC nyinshi ikorerwa muri Hebei ni mesh 80. Nibyiza, mubisanzwe, nibyiza.
. Ninini yohereza urumuri, nibyiza, byerekana ko harimo ibidashobora gukemuka muri byo. . Ubucucike bwa reaction ya vertical muri rusange nibyiza, kandi nibya reaction ya horizontal ni bibi, ariko ntibisobanuye ko ubwiza bwa reaction ya vertical iruta iya reaction ya horizontal, kandi ubwiza bwibicuruzwa bugenwa nibintu byinshi. (4) Uburemere bwihariye: Ninini nini ya rukuruzi, niko iremereye. Umwihariko ni munini, muri rusange kubera ko ibiri mu itsinda rya hydroxypropyl muri yo ari byinshi, kandi ibikubiye mu itsinda rya hydroxypropyl ni byinshi, gufata amazi ni byiza.
Ni ubuhe butumwa nyamukuru bwo gukoresha HPMC mu ifu yuzuye, kandi bibaho muburyo bwa shimi?
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. 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 mumazi numwuka Mubikorwa bya CO2, karubone ya calcium ikorwa, mugihe HPMC igumana amazi gusa, ifasha reaction nziza ya calcium yivu, kandi ntabwo yitabira reaction ubwayo.
Isano iri hagati yubukonje nubushyuhe bwa HPMC, ni iki gikwiye kwitabwaho mubikorwa bifatika?
Ubukonje bwa HPMC buragereranywa nubushyuhe, ni ukuvuga ko ubukonje bwiyongera uko ubushyuhe bugabanuka. Ubukonje bwibicuruzwa dukunze kuvuga bivuga ibisubizo byikizamini cyumuti wacyo wa 2% mubushyuhe bwa dogere selisiyusi 20.
Mubikorwa bifatika, twakagombye kumenya ko mubice bifite itandukaniro rinini ryubushyuhe hagati yizuba nimbeho, birasabwa gukoresha ubukonje buke ugereranije nimbeho, bifasha cyane kubaka. Bitabaye ibyo, iyo ubushyuhe buri hasi, ubukonje bwa selile buziyongera, kandi ukuboko kumva kuremereye mugihe cyo gukuraho.
Ubucucike buciriritse: 75000-100000 bukoreshwa cyane muri putty
Impamvu: gufata neza amazi
Ubukonje bukabije: 150000-200000 bukoreshwa cyane cyane mubice bya polystirene insulaire ya minisiteri ya rubber na vitrifike ya microbead insulation.
Impamvu: ubukonje bwinshi, mortar ntabwo byoroshye kugwa, kugabanuka, biteza imbere ubwubatsi.
