Hydroxypropylmethylcylosellose (HPMC) ndeye yakakosha uye inopindirana ingiro inoshandiswa mune akawanda maindasitiri kusanganisira iyo plaster range. HPMC ndeye cellulose ether inotorwa kubva ku cellulose uye isingaoni, mvura-yemvura polymer. Zvinowanzoshandiswa seye thickkener, stabilizer uye emulsifier mumisika yakanyorova uye yakaoma. Muindasitiri yeGypsum, HPMC inoshandiswa seyakavharidzira uye yakanangana neanoti. Chinyorwa ichi chinonyatsokwanisa zvakanakira kushandisa HPMC muGypsum kugadzirwa.
Gypsum ndeyekuitika kwechisikigo inowanzoitika mineral inoshandiswa mune yekuvaka indasitiri kuburitsa simende uye gypsum. Kuti mugadzire zvigadzirwa zveGypsum, iyo gypsum inofanira kutanga kuongororwa mune yepfuma fomu. Maitiro ekugadzira gypsum poda inosanganisira kupwanya nekukuya zvicherwa, wozozvidza pamhepo dzekupisa kubvisa mvura yakawandisa. Iyo inokonzeresa yakaomeswa poda inosanganiswa nemvura kuti iite paste kana slurry.
Imwe yezvinhu zvakakosha zveHPMC mune yeGypsum indasitiri ndeyekupararira kwayo kugona. Muzvigadzirwa zveGypsum, HpMC zviito sekuparadzira, kuputsa mapundu ezvikamu uye kuona yavo yunifomu yekugovera mukati meiyo slurry. Izvi zvinoguma zvaita svutugadzike, zvakanyanya kuwirirana kuti iri nyore kushanda nayo.
Kuwedzera pakuve anoparadzira, HPMC zvakare iri thickkener. Inobatsira kuwedzera iyo visikopa yeiyo gypsum slurry, zvichiita kuti zvive nyore kubata uye kushandisa. Izvi zvinonyanya kukosha kune zvigadzirwa izvo zvinoda mushe kusawirirana, kwakadai sejoinm compand kana plaster.
Chimwe chinhu chakakosha cheHPMC mune yeGypsum indasitiri ndeyekubata kwayo kwakavandudzwa. Kuwedzera HPMC kuenda kuGypsum Slurries inoita kuti chigadzirwa chacho chapararira nyore uye kushanda kwenguva yakareba. Izvi zvinoreva kuti akakosha uye vanhu vane nguva yakawanda yekushanda pane chigadzirwa isati yamisirwa.
HPMC zvakare inovandudza kunaka uye kujaira kwechigadzirwa chekupedzisira. Nekuita senge inopararira, HPMC inovimbisa kuti ma gypsum zvimedu zvakanyatsogovaniswa muchigadzirwa zvese. Izvi zvinoita kuti chigadzirwa chiwedzerwe chakasimba, chinowirirana uye chisina kujairika kupaza uye kuputsa.
HPMC ndeyezvinofarirwa zvine hushamwari. Izvo zvisiri-zvine muchetura, biodegradable uye haina kukonzera kusvibiswa kwemhepo. Izvi zvinoita kuti ive sarudzo yakanaka kwazvo kune maindasitiri ane hanya nezvekukanganisa kwezvakatipoteredza kwezvigadzirwa zvavo.
HPMC chinhu chakakosha mune yeGypsum mhuri ine zvakawanda zvakanakira zvakanaka. Kugona kwayo kuparadzira, kudzikisira, kuvandudza maitiro uye kuguma zvigadzirwa zvechigadzirwa kwakaita kuti ive chikamu chakakosha chenhaurwa. Hushamwari hwayo hwezvakatipoteredza zvakare hunogona kubatsirwa munyika umo maindasitiri akawanda ari kutarisa kuti aderedze maitiro avo ezvemamiriro ekunze.
mumhedziso
Hydroxypronylmethylcellose (HPMC) chinhu chakakosha musanganiswa muplaster renji. Kugona kwayo kuparadzira, kudzikisira, kuvandudza maitiro uye kupedza chigadzirwa hunhu kwakaita kuti ive yakakosha chikamu chenhare. Uyezve, kushamwaridzana kwaro kwezvakatipoteredza mukana wakakosha munyika umo maindasitiri mazhinji anodiwa kuderedza maitiro avo ezvemamiriro ekunze. Zvakazara, HPMC isarudzo yakanaka kwazvo kune chero indasitiri inotarisa kuti uvandudze kunaka kwezvigadzirwa zvavo apo zvakare kuve nekuziva maitiro avo ezvemamiriro ekunze.
