HPMC esetyenziswa eludongeni putty

1. Zeziphi iimpawu eziphambili zobugcisa ze-hydroxypropyl methyl cellulose (HPMC)?

Umxholo we-HPMC Hydroxypropyl kunye ne-viscosity, abasebenzisi abaninzi banenkxalabo malunga nezi zalathisi zibini.Ukugcinwa kwamanzi ngokuqhelekileyo kungcono kwabo banomxholo ophezulu we-hydroxypropyl.I-viscosity ephezulu, ukugcinwa kwamanzi, ngokuthe ngqo (kunokuba kuphelele) ngcono, kunye ne-viscosity ephezulu, isetyenziswe ngcono kwi-samente mortar.

2. Yintoni umsebenzi ophambili wokusetyenziswa kwe-HPMC kwi-putty eludongeni?

Kwi-putty eludongeni, i-HPMC inemisebenzi emithathu: ukuqina, ukugcinwa kwamanzi kunye nokwakhiwa.

Ukujiya: Iselulosi inokujiya ukuze inqunyanyiswe kwaye igcine iyunifomu yesisombululo, kunye nokuxhathisa ukuhexa.Ukugcinwa kwamanzi: yenza udonga lwe-putty lome kancinci, kwaye uncedise i-calcium engwevu ukuba isabele phantsi kwesenzo samanzi.Ukwakhiwa: I-Cellulose inefuthe lokuthambisa, elinokwenza i-putty eludongeni ibe nokusebenza kakuhle.

3. Ngaba ukuhla kwe-putty eludongeni kunxulumene ne-HPMC?

Ukuhla kwe-putty eludongeni kuhambelana ikakhulu nomgangatho we-ash calcium, kodwa kungekhona kwi-HPMC.Ukuba umxholo we-calcium we-ash calcium kunye nomlinganiselo we-CaO kunye ne-Ca (OH) 2 kwi-ash calcium ayifanelekanga, iya kubangela ukulahleka kwe powder.Ukuba inento yokwenza ne-HPMC, ke ukugcinwa kwamanzi kakubi kwe-HPMC kuya kubangela ukuhla komgubo.

4. Ingakanani ihydroxypropyl methyl cellulose (HPMC) kwi putty eludongeni?

Isixa se-HPMC esisetyenzisiweyo kwizicelo zangempela siyahluka ngokuxhomekeke kwimozulu, ubushushu, umgangatho wekhalsiyam yothuthu lwendawo, ifomula ye-putty eludongeni, kunye "nomgangatho ofunwa ngabathengi".Ngokuqhelekileyo, phakathi kwe-4 kg kunye ne-5 kg.Umzekelo: I-Beijing wall putty ininzi i-5 kg;I-Guizhou ininzi i-5 kg ​​ehlotyeni kunye ne-4.5 kg ebusika;IYunnan incinci ngokwentelekiso, idla ngokuba yi-3 kg ukuya kwi-4 kg njalo njalo.

5. Yintoni i-viscosity efanelekileyo ye-hydroxypropyl methyl cellulose (HPMC)?

I-wall putty yi-100,000 ngokubanzi, kodwa udaka lufuna kakhulu, kwaye kuthatha i-150,000 ukusebenza.Ngaphezu koko, eyona ndima ibalulekileyo ye-HPMC kukugcina amanzi, kulandele ukutyeba.Kwi-putty eludongeni , ngokude nje ukugcinwa kwamanzi kulungile, i-viscosity iphantsi (70-80,000), inokwenzeka kwakhona, ngokuqinisekileyo, i-viscosity iphezulu, kwaye ukugcinwa kwamanzi okuhambelanayo kungcono.Xa i-viscosity idlula i-100,000, i-viscosity ayinayo impembelelo ekugcinweni kwamanzi.

6. Indlela yokukhetha i-hydroxypropyl methylcellulose (HPMC) efanelekileyo ngeenjongo ezahlukeneyo?

Ukusetyenziswa kwe-putty eludongeni : imfuno iphantsi, i-viscosity yi-100,000, yanele, into ebalulekileyo kukugcina amanzi angcono.Ukusetyenziswa komdaka: iimfuno eziphezulu, i-viscosity ephezulu, ingcono kune-150,000, ukusetyenziswa kweglue: iimveliso ezichithwa ngokukhawuleza, i-viscosity ephezulu.

7. Ukusetyenziswa kwe-HPMC kwi-putty eludongeni, yintoni ebangela ukuba i-putty eludongeni ivelise amaqamza?

I-HPMC idlala iindima ezintathu eludongeni lwe-putty: ukuqina, ukugcinwa kwamanzi kunye nokwakhiwa.Musa ukuthatha inxaxheba kuyo nayiphi na impendulo.Izizathu zamaqamza:

(1) Kufakwa amanzi amaninzi kakhulu.
