Ukusetyenziswa kwe-cellulose ether kwi-gypsum mortar

I-cellulose ethers idla ngokusetyenziswa njengezongezo kudaka olusekwe kwigypsum ukomeleza iipropathi ezahlukeneyo kunye neempawu zokusebenza.Oku kulandelayo kusetyenziso oluthile lwe-cellulose ethers kudaka lwegypsum:

Ugcino lwamanzi:

I-cellulose ethers zi-hydrophilic polymers, oku kuthetha ukuba zinobudlelwane obuphezulu bamanzi.Xa zifakwe kwi-plaster mortars, zigcina ngokufanelekileyo ukufuma kwaye zithintela umxube ukuba wome ngokukhawuleza.Oku kubalulekile ukuqinisekisa ukuba udaka lunexesha elaneleyo lokufaka amanzi ngokufanelekileyo kunye nokuphucula ukusebenza.

Ukuqhubekeka kunye nokulula kwesicelo:

Iipropati zokugcina amanzi ze-cellulose ethers zinceda ukuphucula ukusebenza kwe-gypsum mortar.Udaka luba lula ukuxuba, ukusabalalisa kunye nokusebenzisa, ukwenza inkqubo yokwakha ibe lula kwaye isebenze ngakumbi.

Nciphisa ukushwabana:

I-cellulose ethers inceda ukulawula ukomisa ukuncipha kodaka lwegypsum.Ngokugcina umxholo wamanzi owaneleyo ngexesha lokumisa kunye nokumisa, i-cellulose ethers inceda ukunciphisa ukuchithwa kwe-shrinkage kunye nokuqinisekisa ukuzinza kwe-dimensional yemveliso egqityiweyo.

Phucula ukuncamathela:

I-cellulose ethers iphucula ukunamathela kwe-gypsum mortar kwiintlobo ezahlukeneyo ze-substrates, kubandakanywa iindonga kunye neesilingi.Oku kubaluleke kakhulu kwizicelo ezifana nokutyatyekwa kunye nokunikezelwa, apho ibhondi eyomeleleyo ibaluleke kakhulu ebukhoneni kunye nobomi obude bomphezulu ogqityiweyo.

Ukuchasana nokuqhekeka:

Ukongeza i-cellulose ether kunokuphucula ukuxhathisa kokuqhekeka kodaka.Oku kunenzuzo ngokukhethekileyo kwiindawo apho ukunyakaza kwesakhiwo kulungele ukwenzeka okanye apho udaka lunokugxininiswa, njenge-compound edibeneyo kunye ne-putty layers.

Anti-sag:

Ukusetyenziswa okuthe nkqo, okufana neeplates eludongeni, i-cellulose ethers isebenza njengezinto ezityebisayo, ezinciphisa i-sag kunye nokudilika kodaka.Olu phawu lunceda ukugcina ubukhulu obufanayo kwiindawo ezithe nkqo, ukuphucula i-aesthetics kunye nokusebenza kwesicelo sokugqibela.

Nyusa umanyano:

I-cellulose ethers inegalelo ekudibaniseni umxube wodaka, ukuphucula ukunyaniseka kwayo kwesakhiwo.Oku kubalulekile kwizicelo apho udaka lufuna ukumelana namandla angaphandle okanye uxinzelelo.

Uzinzo lokunyibilika komkhenkce:

I-cellulose ethers inokomeleza uzinzo lokunyibilika komkhenkce kwiidaka zegypsum, zizenze zixhathise ngakumbi kumonakalo kwindawo enamaqondo obushushu aguqukayo.Oku kubaluleke ngakumbi kwizicelo zokwakha ezivezwe kwiimeko ezimandundu zemozulu.

Yandisa ixesha lokumisela:

Ukusebenzisa i-cellulose ethers kunokwandisa ixesha lokumisela udaka lwe-plaster, ukuvumela ukuguquguquka okukhulu kwisicelo kunye nokugqiba.Oku kuluncedo ngakumbi kwiimeko apho kufuneka iiyure ezinde zokusebenza.

Iimpawu eziphuculweyo zerheological:

I-cellulose ethers igalelo kwiipropati ze-rheological zodaka, ezichaphazela ukuhamba kwayo kunye neempawu zokuguqulwa.Oku kunceda ukufezekisa ukuhambelana okufunekayo kunye nokusebenza kwesicelo.

Kubalulekile ukuba uqaphele ukuba uhlobo oluthile kunye ne-dosage ye-cellulose ether esetyenzisiweyo kunye nokuqulunqwa kwe-gypsum mortar kufuneka kuqwalaselwe ngokucophelela ukufezekisa iziphumo ezifunwayo kwisicelo esinikezelweyo.Abavelisi bahlala besenza uvavanyo kunye nokuphucula ukumisela owona mxholo we-cellulose ether osebenzayo kwiimveliso zabo ezithile kunye nokusetyenziswa okujoliswe kuko.
