Ukubaluleka kwe-HPMC ekugcinweni kwamanzi kwesamente

I-Hydroxypropyl methylcellulose (HPMC) sisithako esisetyenziswa kakhulu kushishino lokwakha, ingakumbi kwi-mortar. Njenge-compound ene-molecular ephezulu, i-HPMC ineempawu eziyenza isebenze kakuhle ekugcinweni kwamanzi, ekuqineni, ekuthambiseni, ekuzinzeni nasekuphuculeni ukunamathela.

(1) Iimpawu zeekhemikhali kunye nendlela yokusebenza kwe-HPMC

I-HPMC yi-non-ionic cellulose ether efunyenwe ngokuguqulwa kweekhemikhali ze-cellulose yendalo. Amaqela e-hydroxypropyl kunye ne-methyl kwisakhiwo sayo se-molecular ayinika ukunyibilika okuhle kunye ne-viscosity. Ezi mpawu zeekhemikhali zenza i-HPMC idlale ezi ndima zilandelayo zibalulekileyo kwi-mortar:

1.1 Ukusebenza kokugcinwa kwamanzi

Ukusebenza kokugcinwa kwamanzi kwe-HPMC ikakhulu kuvela kumaqela athanda amanzi kwisakhiwo sayo semolekyuli. La maqela anokwenza iibhondi ze-hydrogen kunye neemolekyuli zamanzi, ngaloo ndlela efunxa kwaye egcina amanzi ngempumelelo. Ngexesha lenkqubo yokwakha i-mortar, i-HPMC inokunciphisa ukufuma kwamanzi, igcine umxholo womswakama kwi-mortar, kwaye iqinisekise ukuba isamente ifumana amanzi aneleyo.

1.2 Isiphumo sokuqina

I-HPMC ikwadlala indima yokutyeba kwi-mortar. Isisombululo esiqinileyo esenziwe emva kokunyibilika kwayo sinokwandisa ukuhambelana kwe-mortar, okwenza kube lula ukwakhiwa nokuma kwayo. Oku akuphuculi nje kuphela ukusebenza kokwakhiwa kwe-mortar, kodwa kunciphisa nokugoba kwe-mortar kumphezulu othe nkqo.

1.3 Isiphumo sokuthambisa kunye nokuzinzisa

Isiphumo sokuthambisa se-HPMC senza i-mortar ibe lula ngexesha lokuxuba nokwakha, nto leyo enciphisa ubunzima bokwakha. Kwangaxeshanye, i-HPMC inozinzo oluhle, olunokuphucula amandla e-mortar okulwa nokwahlulwahlulwa kwaye luqinisekise ukusasazwa okufanayo kwezixhobo ze-mortar. 

(2) Ukusetyenziswa okukhethekileyo kwe-HPMC ekugcinweni kwamanzi kwi-mortar

I-HPMC isetyenziswa kakhulu kwiintlobo ezahlukeneyo zeemortar, kwaye isiphumo sayo sokugcina amanzi sinegalelo elikhulu ekuphuculeni ukusebenza kwemortar. Nazi iindlela ezithile zokusetyenziswa kwe-HPMC kwiimortar ezininzi eziqhelekileyo:

2.1 Udaka oluqhelekileyo lwesamente

Kwisigqubuthelo sesamente esiqhelekileyo, isiphumo sokugcina amanzi se-HPMC sinokuthintela ngempumelelo isigqubuthelo ukuba singalahlekelwa ngamanzi ngokukhawuleza ngexesha lokwakhiwa, ngaloo ndlela kuthintelwe ingxaki yokuqhekeka kwesigqubuthelo kunye nokulahleka kwamandla. Ingakumbi kwiindawo ezinobushushu obuphezulu nendawo eyomileyo, ukusebenza kokugcina amanzi kwe-HPMC kubaluleke kakhulu.

2.2 Udaka oludibanisayo

Kwi-bonding mortar, isiphumo sokugcina amanzi se-HPMC asincedi nje kuphela ekumanziseni isamente, kodwa sikwaphucula amandla okubopha phakathi kwe-motar kunye ne-substrate. Oku kubaluleke kakhulu ekwakhiweni kwe-paving yezinto ezifana neethayile namatye, kwaye kunokuthintela ngempumelelo ukwenzeka kokuqhekeka nokuwa.

2.3 Udaka oluzilinganisayo

I-mortar ezenzela ngokwayo ifuna ukutyibilika okuhle kunye neempawu zokuziqinisa. Iziphumo zokuqina kunye nokugcinwa kwamanzi ze-HPMC zinokuphucula ukusebenza kolwakhiwo lwe-mortar ezenzela ngokwayo, ukuqinisekisa ukuba ayizukulahlekelwa ngamanzi ngokukhawuleza ngexesha lokuhamba kunye nenkqubo yokuziqinisa ngokwayo, ngaloo ndlela iqinisekisa umgangatho wolwakhiwo.

2.4 Udaka lokuvala ubushushu

Ii-aggregates ezilula zihlala zongezwa kwi-insulation mortar, nto leyo eyenza ukusebenza kokugcinwa kwamanzi kwe-mortar kubaluleke kakhulu. Isiphumo sokugcina amanzi se-HPMC sinokuqinisekisa ukuba i-insulation mortar igcina umswakama ofanelekileyo ngexesha lokwakhiwa nokuqina, kuthintelwe ukuqhekeka nokuncipha, kwaye kuphuculwe isiphumo sokukhusela kunye nokuqina kwe-mortar.

(3) Iingenelo ze-HPMC ekugcinweni kwamanzi kwi-mortar

3.1 Ukuphucula ukusebenza kolwakhiwo

Isiphumo sokugcina amanzi se-HPMC kwi-mortar sinokuyiphucula kakhulu indlela yokwakha i-mortar. Imiphumo yayo yokutyeba kunye nokuthambisa yenza kube lula ukuyisebenzisa nokuyila i-mortar, nto leyo enciphisa ubunzima kunye nobunzima bomsebenzi ngexesha lenkqubo yokwakha. Kwangaxeshanye, ukusebenza kokugcina amanzi kwe-HPMC kunokwandisa ixesha lokuvula i-mortar, kunike abasebenzi bokwakha ixesha elingakumbi lokusebenza.

3.2 Phucula umgangatho wesamente

Isiphumo sokugcina amanzi se-HPMC sinceda ekufumaneni amanzi ngokupheleleyo kwisamente, ngaloo ndlela siphucula amandla kunye nokuqina kwesamente. Ukusebenza kakuhle kokugcina amanzi kunokuthintela ukuba isamente ingaqhekeki kwaye inciphe ngexesha lenkqubo yokuqina, okuqinisekisa umgangatho kunye nesiphumo sokwakhiwa kwayo.

3.3 Ukonga iindleko

Ukusetyenziswa kwe-HPMC kunokunciphisa ubungakanani besamente kwi-mortar, ngaloo ndlela kunciphisa iindleko zokwakha. Ukusebenza kwayo kokugcina amanzi kwenza ukuba amanzi kwi-mortar asetyenziswe ngokufanelekileyo, kunciphisa ukulahleka kwamanzi kunye nenkunkuma. Kwangaxeshanye, i-HPMC inokunciphisa izinga lokulungiswa kwakhona kwe-mortar ngexesha lokwakha, nto leyo egcina iindleko ngakumbi.

Ukubaluleka kwe-HPMC ekugcinweni kwamanzi kwi-mortar kuyabonakala. Iimpawu zayo ezikhethekileyo zeekhemikhali kunye nendlela esebenza ngayo zenza ukuba idlale indima ebalulekileyo ekuphuculeni ukugcinwa kwamanzi, ukusebenza kolwakhiwo kunye nomgangatho ngokubanzi we-mortar. Ngophuhliso lweshishini lokwakha, ukusetyenziswa kwe-HPMC kuya kuba kubanzi nangakumbi, kwaye kuqhubeke negalelo ekuphuculweni kokusebenza kunye nokuqinisekiswa komgangatho we-mortar kunye nezinye izixhobo zokwakha.
