Yintoni i-HPMC yodaka oluxutywe owomileyo?

1. Inkcazo ye-HPMC
HPMC (Hydroxypropyl Methyl Cellulose)i-ether ye-cellulose engekho i-ionic esetyenziswa ngokubanzi kwizinto zokwakha, amayeza, ukutya, iikhemikhali zemihla ngemihla kunye namanye amashishini. Kwi-dry-mixed mortar, i-AnxinCel®HPMC isetyenziswa kakhulu njenge-thickener, i-agent egcina amanzi kunye ne-modifier, enokuphucula kakhulu ukwakhiwa kodaka.

2. Indima ye-HPMC kumdaka oxutywe owomileyo

Imisebenzi ephambili ye-HPMC kudaka oluxutyiweyo olomileyo yile ilandelayo:

Ukugcinwa kwamanzi: I-HPMC inokufunxa amanzi kwaye idumbe, yenze ifilimu ye-hydration ngaphakathi kodaka, ukunciphisa ukukhuphuka kwamanzi ngokukhawuleza, ukuphucula ukusebenza kakuhle kwe-samente okanye i-gypsum, kunye nokuthintela ukuqhekeka okanye ukulahlekelwa kwamandla okubangelwa ukulahlekelwa kwamanzi amaninzi.

Ukutyebisa: I-HPMC inika udaka i-thixotropy elungileyo, yenza udaka lube neendawo ezifanelekileyo zokumanzi kunye nezakhiwo zokwakha, kunye nokuthintela ukuqhekeka kwamanzi kunye nentlenga okubangelwa kukwahlulwa kwamanzi.

Ukuphucula ukusebenza kolwakhiwo: I-HPMC iphucula i-lubricity yodaka, yenza kube lula ukuyisebenzisa kunye nenqanaba, ngelixa iphucula ukunamathela kwi-substrate kunye nokunciphisa umgubo kunye nomgodi.

Yandisa ixesha elivulekileyo: I-AnxinCel®HPMC inokunciphisa izinga lokunyuka kwamanzi, yandise ixesha elisebenzayo lodaka, yenza ulwakhiwo lube bhetyebhetye, kwaye lufaneleke ngokukodwa usetyenziso lwendawo enkulu kunye neendawo zokwakha ezinobushushu obuphezulu.

I-Anti-sagging: Kwizinto zokwakha ezithe nkqo njengezinto zokuncamathelisa iithayile kunye ne-putty, i-HPMC inokuthintela izinto ukuba zingatyibiliki ngenxa yobunzima bayo kunye nokuphucula uzinzo lokwakha.

3. Ukusetyenziswa kwe-HPMC kwiifama ezahlukeneyo ezinomxube owomileyo

I-HPMC isetyenziswa ngokubanzi kwiindidi ezahlukeneyo zodaka oluxutywe okomileyo, kubandakanywa kodwa kungaphelelanga apho:

Udaka lweMasonry kunye nodaka lokutyabeka: phucula ukugcinwa kwamanzi, ukuthintela ukuqhekeka kodaka, kunye nokuphucula ukunamathela.

Ukunamathiswa kwethayile: phucula ukuncamathelisa, phucula ukwakhiwa lula, kwaye uthintele iithayile ekutyibilikeni.

Udaka oluzilinganisa ngokwalo: phucula ubumanzi, uthintele ukuqina, kwaye wongeze amandla.

Udaka olungenamanzi: ukuphucula ukusebenza kwamanzi kunye nokwandisa ubuninzi bodaka.

Iputty powder: phucula ukusebenza kolwakhiwo, ukomeleza ukuxhathisa kokukhuhla, kwaye uthintele umgubo.

4. Ukukhetha HPMC kunye nokusetyenziswa izilumkiso

Iimveliso zodaka ezahlukeneyo zineemfuno ezahlukeneyo ze-HPMC, ke ezi zinto zilandelayo kufuneka ziqwalaselwe xa ukhetha:

Viscosity: Low-viscosity AnxinCel®HPMC ilungele self-leveling udaka kunye fluidity elungileyo, ngelixa high-viscosity HPMC ilungele putty okanye ithayile ancamatheliswe ngamanzi aphezulu.iimfuno zokugcina.

Ukunyibilika: Umgangatho ophezulu we-HPMC kufuneka ube nokunyibilika okulungileyo, ukwazi ukusasaza ngokukhawuleza kwaye wenze isisombululo esifanayo ngaphandle kwe-agglomeration okanye i-agglomeration.
Isixa esongezelelweyo: Ngokuqhelekileyo, inani elongezelelweyo le-HPMC kwi-dry-mixed mortar yi-0.1% ~ 0.5%, kwaye umlinganiselo othile kufuneka ulungelelaniswe ngokweemfuno zokusebenza zodaka.

HPMCyinto eyongeziweyo eyongezelelweyo kwi-dry-mixed mortar, enokuphucula ukusebenza kokwakhiwa, ukugcinwa kwamanzi kunye nokunamathela kodaka. Isetyenziswa ngokubanzi kwi-masonry mortar, udaka lokutyabeka, i-adhesive tile, i-putty kunye nezinye iimveliso. Xa ukhetha i-HPMC, kuyimfuneko ukufanisa i-viscosity efanelekileyo kunye nefomula ngokwemeko yesicelo esithile ukuqinisekisa isiphumo esihle sokwakha.
