Usebenzisa i-hydroxypropyl methylcelcelgalose hpmc in gypsum

I-HydroxyPOpyl Methylcelceltulose (HPMC) sisisele i-seluplose i-Ether isetyenziswa ngokuqhelekileyo kumashishini ahlukeneyo, kubandakanya ne-gypsum kwishishini lokwakha. Le ngqokelela yeqela elininzi idlala indima ebalulekileyo ekuphuculeni intsebenzo kunye neepropathi ze-gypsim.

1. Intshayelelo kwi-HPMC:

I-Hydroxypropyl Methylcelcelcelose yinto yokwahlulwa kwe-polymer yendalo yendalo. Yenziwe ngokunyanga isellulose kunye ne-propylene oxide kunye ne-methyl chloride. Isiphumo sisipomo esinyibilikayo samanzi ngepropathi eyahlukileyo enokufumana izicelo kuluhlu olubanzi lwamashishini.

I-2. Ukusebenza kwe-HPMC:

I-Solity yaManzi: I-HPMC inyibilika ngokulula emanzini, yenza isisombululo esingenamibala.
Iipropathi zokwenza ifilimu: Ukusekwa kweepropathi zokwenza ifilimu uncedo lwefilimu yokukhusela kumphezulu.
I-thermal gallge: i-HPMC iphantsi kwengqolowa ye-thermal ejijekileyo, oko kuthetha ukuba inokwenza ijeli kumaqondo obushushu aphezulu kwaye ibuyele kwisisombululo ekupholeni.
I-Viskosity: UVenkile wesisombululo se-HPMC unokuhlengahlengiswa ngokusekwe kwinqanaba lokufaka kunye nobunzima bemolekyuli.

I-3. Ukusetyenziswa kwe-HPMC eGypsum:

Ukugcinwa kwamanzi: i-HPMC isebenza njengearhente yokugcina amanzi eGypsum, ukuthintela ukuphulukana namanzi ngexesha lokuseta. Oku kuphucula i-cunepensiles kwaye ibonelela ngobomi obuninzi besicelo.
Ukuphuculwa komthendeleko: Iipropathi zokwenza ifilimu ze-HPMC Uncedo lokuphucula i-Stucco Abinces kwiindidi zendawo, ukudala iqhina elinamandla.
Ulawulo lokungaguquguquki
Ukunganyangeki: Sebenzisa i-HPMC kwi-plaster kunceda ukuphucula uguquko kwaye kunciphise amathuba okuqhekeka kwimveliso egqityiweyo.
Ukuseta ixesha: I-HPMC inokuphembelela ixesha le-gypsum ukuze ilungiswe ukufezekisa iimfuno ezithile zesicelo.

4. Umthamo kunye nokuxuba:

Isixa se-HPMC esisetyenziselwa i-GYPSUM ixhomekeke kwimiba eyahlukeneyo enjengeepropathi ezinqwenelekayo, ukwenziwa kweGypsim kunye neemfuno zesicelo. Ngokwesiqhelo, yongezwa kumxube owomileyo ngexesha lokuxuba. Inkqubo yokuxuba ibaluleke kakhulu ukuqinisekisa ukusasazeka okufanayo kunye nokusebenza ngokugqibeleleyo.

5.Cofatimes kunye nokhuseleko:

I-HPMC iyahambelana nezinye iintlobo zongeziweyo ezisetyenziselwa ukwenziwa kwe-plaster. Ukongeza, kuthathwa njengekhuselekile ukuba isetyenziswe kwizinto zokwakha kwaye zihambelana nemigangatho efanelekileyo yolawulo.

6. ISIQINISEKISO:

I-HydroxyPOpyl Methylcelceltulose (HPMC) idlala indima ebalulekileyo ekuphuculeni intsebenzo ye-gyppum. Ipropathi yayo eyahlukileyo inceda ukuphucula ukusebenza, ukunamathela kunye nomgangatho we-Plaster. Ishishini elisetyenziswe ngokubanzi kwishishini lokwakha, i-HPMC ihlala icandelo elibalulekileyo lemigangatho ephezulu ye-plate.
