Ukusetyenziswa kwe-Hydroxypropyl Methyl Cellulose kwi-Gypsum Mortar

(1), iimpawu zei-hydroxypropyl methylcellulose kwi-gypsum mortar:

1. Ukusebenza kakuhle kokwakhiwa: kulula kwaye kulula ukuxhoma, inokubunjwa ngexesha elinye, kwaye ibe neplastiki ngexesha elifanayo.

2. Ukuhambelana okuqinileyo: Kufanelekile kuzo zonke iintlobo zesiseko se-gypsum, kwaye kunokunciphisa ixesha lokucwila kwe-gypsum, ukunciphisa izinga lokunciphisa ukomisa, kwaye udonga alulula ukugoba kunye nokuqhekeka.

3. Izinga elilungileyo lokugcinwa kwamanzi: linokwandisa ixesha lokusebenza kwesiseko se-gypsum, ukuphucula ukunyanzeliswa kobunzima besiseko se-gypsum, ukwandisa amandla okubambisana phakathi kwesiseko se-gypsum kunye nesiseko sesiseko, ukusebenza kakuhle kokubambisana okumanzi, kunye nokunciphisa umlotha wokufika kunye nezinye iingxaki.

4. Ukuphucula izinga lokusasazeka kwesiseko se-gypsum: Xa kuthelekiswa ne-hydroxypropyl methylcellulose ether efanayo, izinga lokusasazeka liya kwandiswa kakhulu. Iimveliso zeHydroxypropyl methylcellulose zinokunyusa kakhulu izinga lokugquma, zinokugubungela iindawo ezininzi, zinokunciphisa ukuqina kwabasebenzi, zonga izixhobo, kwaye ziphucule iinzuzo zoqoqosho.

5. Ukusebenza kakuhle kwe-anti-sagging: xa uxhoma iileya ezingqingqwa, ukwakhiwa kwe-single-pass akuyi kugoba, kwaye ngaphezulu kweepaseji ezimbini, ngaphezulu kwe-3cm, aziyi kuncipha xa zixhonywa, kwaye iplastiki ilungile.

6. Iinkalo zesicelo kunye ne-dosage: i-gypsum ephantsi yokukhanya ephantsi, i-dosage ecetyiswayo yi-2.5-3.5 kg / toni.

(2) Uvavanyo lovavanyo lwesicelo se-hydroxypropyl methylcellulose:

1. Uvavanyo lwamandla: Emva kovavanyo, i-gypsum-based hydroxypropyl methylcellulose inamandla okudibanisa okuqinileyo kunye namandla oxinzelelo.

2. Uvavanyo lwe-Anti-sagging: Akukho sag xa ulwakhiwo lwepasi enye lusetyenziswa kumaleko ashinyeneyo, kwaye akukho sag xa isetyenziselwa ukudlula ngaphezulu kwesibini (ngaphezu kwe-3cm), kwaye iplastiki ilungile.

3. Uvavanyo lokuxhoma eludongeni: lulula kwaye lugudile xa lujinga, kwaye lunokubunjwa ngexesha elinye. Umphezulu uthambile kwaye uthambile, unokukhanya.

4. Uvavanyo lwesantya sokusasazeka: Isantya sokusasazeka kwesiseko segypsum sibhekisa kwisiphumo esifunyenwe ngokulinganisa ubuninzi obumanzi besiseko segypsum. Itoni enye yemveliso esekwe kwigypsum yolwakhiwo lwendawo eludongeni olungqindilili lwe-10mm.

5. Uvavanyo lwezinga lokugcinwa kwamanzi: Ireyithi yokugcinwa kwamanzi ireferensi yomgangatho we-GB/T28627-2012 “Plastering Gypsum”, izinga lokugcinwa kwamanzi kwi-gypsum yokukhanya ephantsi kwe-gypsum inkulu okanye ilingana ne-60%, kunye ne-0.2% kunye ne-0.25% ye-gypsum-based i-hydroxypropyl methylcellulose yongezwa Inokusebenza kakuhle kokugcinwa kwamanzi.
