HPMC esetyenziswa ekwakheni

I-HPMC Hydroxypropyl methyl cellulose, ekwabizwa ngokuba yi-hydroxypropyl methyl cellulose ether (HPMC), i-cellulose hydroxypropyl methyl ether, kukukhethwa kweselulosi yomqhaphu esulungekileyo kakhulu njengezinto ezikrwada, phantsi kweemeko zealkali ngokufakwa okukhethekileyo kunye nokulungiswa.

I-Hydroxypropyl methyl cellulose HPMC esetyenziselwa ulwakhiwo, i-ether ye-cellulose eyongeziweyo iphantsi kakhulu, kodwa inokuphucula kakhulu ukusebenza kodaka olumanzi, ukusebenza kodaka lodaka lulongezelelo olukhulu. Ngoku, i-hydroxypropyl methyl cellulose esetyenziswa kwi-edry mortar cellulose ether ikakhulu yi-hydroxypropyl methyl cellulose ether (HPMC). I-Hydroxypropyl methyl cellulose kulwakhiwo lodaka olomileyo I-HPMC idlala indima enkulu ekugcineni amanzi, ukuqina, ukuphucula ukusebenza kolwakhiwo.

1, udaka lolwakhiwo lokutyabeka udaka

Ukugcinwa kwamanzi aphezulu kunokwenza i-samente izaliswe ngokupheleleyo, ikhulise kakhulu amandla ebhondi, kwaye inokuphucula ngokufanelekileyo amandla okuqina kunye namandla okucheba, ukuphucula kakhulu umphumo wokwakha, ukuphucula ukusebenza kakuhle.

I-2, i-putty yokumelana namanzi

Kwi-putty ye-HPMC i-hydroxypropyl methyl cellulose ether idlala indima enkulu yokugcina amanzi, ukudibanisa kunye nokuthambisa, ukunqanda isiganeko sokuqhekeka kunye nokuphelelwa ngamanzi emzimbeni okubangelwa ukulahleka kwamanzi ngokukhawuleza, kunye nokuphucula ukunamathela kwe-putty, ukunciphisa isiganeko sokuhamba okujingayo. ulwakhiwo, ukuze ulwakhiwo lube lula.

3, ipeyinti gypsum series

Kuthotho lwegypsum yeemveliso HPMC hydroxypropyl methyl cellulose ether ikakhulu ukudlala ukugcinwa kwamanzi, ukwandisa ukuthanjiswa kunye nezinye iziphumo, kwangaxeshanye inesiphumo ethile ukulibaziseka, ukusombulula inkqubo yokwakhiwa igubu ngokuqhekeka, amandla okuqala ayikho kwingxaki, inokwandisa ixesha elide. ixesha lokusebenza.

4, i-arhente yojongano

Isetyenziswa kakhulu njenge-thickener, inokuphucula amandla okuqina kunye nokomelela kokucheba, iphucule ukugquma komhlaba, iphucule ukunamathela kunye nokomelela kwebhondi.

5, udaka lwangaphandle lokugquma

I-HPMC Hydroxypropyl methyl cellulose, i-ether ye-cellulose kwizinto ezigxininisekileyo kwi-bonding, ukwandisa amandla, ukwenza kube lula ukugquma kodaka, ukuphucula ukusebenza kakuhle, kwangaxeshanye ukuxhathisa ukuhamba ngokuthe nkqo, ukugcinwa kwamanzi aphezulu kunokunyusa ixesha lokusebenza lodaka, ukuphucula i-shrinkage kunye nokumelana nokudinwa kwe-thermal, ukuphucula umgangatho ophezulu, ukuphucula amandla okudibanisa.

6, i-ceramic tile binder

Ukugcinwa kwamanzi aphezulu akukwazi ukucwiliswa kwangaphambili okanye kumanzi i-tile ye-ceramic kunye nesiseko, iphucula ngokubonakalayo amandla ayo ebhondi, i-slurry ingaba ngumjikelo wokwakha omde, ubuthathaka, ufanayo, ulwakhiwo olufanelekileyo, kwaye lunokuxhathisa okulungileyo kumanzi.

I-7, i-ejenti yokuzalisa i-seam, i-arhente yokudibanisa

Ukongezwa kwe-hydroxypropyl methyl cellulose HPMC cellulose ether yenza ukuba ibe ne-adhesion edge enhle, i-shrinkage ephantsi kunye nokumelana nokugqoka okuphezulu, ukukhusela izinto ezisisiseko kumonakalo womatshini, ukuphepha impembelelo yokungena kwisakhiwo sonke.

8, imathiriyeli yokuziphakamisa

I-Hydroxypropyl methyl cellulose cellulose i-ether bond ezinzileyo yokuqinisekisa ubukho bemali elungileyo kunye nokukwazi ukuzilinganisa, ukulawula izinga lokugcinwa kwamanzi ukuze ikwazi ukuqinisa ngokukhawuleza, ukunciphisa ukuqhekeka kunye nokunciphisa.

9. Ipeyinti yeLatex

I-Hydroxypropyl methyl cellulose kushishino lokugquma i-cellulose ether njengefilimu-yangaphambili, i-agent etyebisayo, i-emulsifier kunye ne-stabilizer esetyenzisiweyo, iyenze ibe nokuxhathisa okulungileyo kwe-abrasion, ukugquma, ukunamathela, ukuphucula umgangatho wexabiso le-PH yoxinzelelo lomphezulu, kunye nesiphumo somxube we-solvent. ingcono kwakhona, ukusebenza kweGao Baoshui kuyenza ibe nepropathi elungileyo yokuxukuxa kunye nokuhamba.

10. Iiseramikhi zobusi

Kwiiseramics ezintsha ze-honeycomb, i-billet inikwe i-lubricity, ukugcinwa kwamanzi kunye nokuphucula amandla.

Iimveliso ezigqwesileyo ze-hydroxypropyl methyl cellulose zinokucombulula ngempumelelo ingxaki yokugcinwa kwamanzi phantsi kobushushu obuphezulu. Ngexesha lobushushu obuphezulu, ngakumbi kwiindawo ezishushu nezomileyo kunye nolwakhiwo olubhityileyo kwicala elinelanga, umgangatho ophezulu weHPMC uyafuneka ukuze kuphuculwe ukugcinwa kwamanzi eludaka. Umgangatho ophezulu we-HPMC, ukufana kuhle kakhulu, amaqela ayo e-methoxy kunye ne-hydroxypropyl ecaleni kwe-cellulose molecular chain ukuhanjiswa kweyunifomu, inokuphucula i-hydroxyl kunye ne-ether bond kwii-athom ze-oksijini kunye nombutho wamanzi we-hydrogen bond bond, ukwenza amanzi akhululekile kumanzi adibeneyo, ukuze asebenze ngokufanelekileyo. lawula ukuphuphuma kwamanzi okubangelwa yimozulu yobushushu obuphezulu, ukufezekisa ukugcinwa kwamanzi aphezulu.

Umgangatho ophezulu we-hydroxypropyl methyl cellulose unokusasaza ngokulinganayo nangokufanelekileyo kudaka lwesamente kunye neemveliso zesamente, kwaye upakishe onke amasuntswana aqinileyo, kwaye wenze umaleko wefilimu yokumanzisa, ukufuma kwisiseko ixesha elide kukhutshwe ngokuthe ngcembe, kunye ne-inorganic cementitious material hydration reaction. , ukwenzela ukuba kuqinisekiswe amandla ebhondi kunye namandla oxinzelelo lwezinto. Ke ngoko, kulwakhiwo oluphezulu lobushushu ehlotyeni, ukuze kuphunyezwe isiphumo sogcino lwamanzi, ngokwendlela yokongeza iimveliso zeHPMC ezikumgangatho ophezulu, kungenjalo, kuya kubakho ukomisa ngokukhawuleza okubangelwa kukungena kwamanzi aneleyo, ukunciphisa amandla, ukuqhekeka, igubu elingenanto kwaye ukuwa kunye nezinye iingxaki ezisemgangathweni, kodwa ukwandisa ubunzima bokwakha abasebenzi. Njengoko ubushushu buyancipha, inani le-HPMC lingancitshiswa ngokuthe ngcembe, kwaye umphumo ofanayo wokugcinwa kwamanzi unokufumaneka.
