Basa reHPMC mune simende-based tile adhesives

(1) Mhedziso yeHPMC

Hydroxypropyl Methyl Cellulose (HPMC) isiri-ionic cellulose ether inowanzoshandiswa mukuvaka zvinhu.HPMC ine yakanakisa kunyungudika kwemvura, kuchengetwa kwemvura, firimu-kugadzira zvivakwa uye kugadzikana, uye inoshandiswa zvakanyanya mukuvaka zvinhu zvakaita semataira anonamira, putty poda, gypsum board uye yakaoma dhaka.Mune simende-based tile adhesives, HPMC inoita basa rakakosha, uye basa rayo rinonyanya kuratidzwa mukuvandudza mashandiro ekuvaka, kuwedzera simba rekubatanidza, kuwedzera nguva yakavhurika, uye kuwedzera anti-slip zvivakwa.

(2) Basa reHPMC mune simende-based tile adhesives

1. Kuvandudza kushanda kwekuvaka
HPMC inogona kunyatso kuvandudza mashandiro ekuvaka simende-based tile adhesives, ayo anonyatso kuratidzwa mune zvinotevera zvinhu:

Kuwedzera rheology: HPMC inowedzera viscosity yekunamatira kuburikidza nekukora kwayo, zvichiita kuti zvive nyore kuparadzira uye kugadzirisa, nekudaro kunatsiridza kuve nyore kwekuvaka.Rheology yakakodzera inovimbisa kuti iyo yakanamatira inogona kuumba yunifomu yekubatanidza dhizaini pamadziro kana pasi, iyo inonyanya kukosha yekuisa mataira makuru.

Natsiridza kuchengetwa kwemvura: HPMC ine yakanakisa kuchengetedza mvura uye inogona kukiya mvura mune inonamira kudzivirira mvura kuti ibude nekukasira.Izvi hazvingobatsiri simenti kuti inyatso hydrate, asiwo inowedzera nguva yakazaruka yekunamatira, zvichibvumira vashandi vekuvaka nguva yakawanda yekugadzirisa nekugadzirisa nzvimbo yematairi.

Kuvandudza anti-slippage: Pakuisa mataira, kunyanya matiles akakura pamadziro akatwasuka, dambudziko rekutsvedza kwetairi rinowanzonetsa vashandi vekuvaka.HPMC inowedzera viscosity yekunamatira, ichibvumira matiles kuti akurumidze kuwana imwe yekutanga yekubatanidza simba mushure mekuiswa, nekudaro zvinobudirira kudzivirira kutsvedza.

2. Kuvandudza chisungo simba
HPMC inogona kuvandudza zvakanyanya kusimba kwechisungo chesimende-based tile adhesives nekuti inogona kuita basa mune zvinotevera zvinhu:

Kurudzira simende hydration: Iyo yekuchengeta mvura pfuma yeHPMC inogona kuchengetedza hunyoro mune inonamira uye kukurudzira yakawanda yakakwana hydration ye simende.Chimiro chematombo esimende chakaumbwa nekuzara kwe hydration ye simenti yakaoma, nekudaro ichiwedzera kusimba kwechisungo chekunamatira.

Enhanced interface effect: HPMC inogona kuumba firimu repolymer rakatetepa pakati pekunamatira uye tile.Iyi firimu ine yakanaka kunamatira uye kuchinjika, iyo inogona kunyatso kusimudzira iyo interfacial simba pakati pekunamatira uye tile base base uye kuvandudza iyo yakazara yekubatanidza simba.

3. Yakawedzerwa nguva yakazaruka
Nguva yakazaruka inoreva nguva kubva pakushandiswa kwekunamatira kusvika pakuisa tile.Iyo yekuchengetedza mvura uye rheological control zvivakwa zveHPMC zvinogona kuwedzera nguva yakavhurika yesimende-based tile adhesives, iyo inonyanya kuratidzwa mune zvinotevera zvinhu:

Kunonoka kubuda kwemvura: Iyo firimu repolymer rakagadzirwa neHPMC rinogona kuderedza kubuda kwemvura kubva painamira, kuitira kuti inonamira ichengetedze kushanda kwenguva yakareba.

Ramba wakanyorova: Nekuda kweiyo hygroscopicity yeHPMC, iyo yekunamatira inogona kuramba yakanyorova kwenguva yakareba, nekudaro ichiwedzera hwindo rekushanda uye kuwedzera kugadzirisa uye kuisa nguva yevashandi vekuvaka.

4. Kuwedzera kurwisa-slip performance
Anti-slip performance (Anti-slip performance) inoreva kuramba kwematiles kuti aendeswe nekuda kwehuremu hwawo kana simba rekunze paanongoiswa.Iko kukora uye gelling mhedzisiro yeHPMC inogona kukwidziridza anti-slip zvivakwa zve simende-based tile adhesives mune zvinotevera zvinhu:

Kuvandudza kunamatira kwekutanga: HPMC inovandudza kunamatira kwekutanga kwekunamatira, ichibvumira matiles kuti akurumidze kuwana yakagadzikana chinzvimbo mushure mekuisa uye kuderedza kutamiswa.

Kugadzira iyo elastic chimiro: Iyo network dhizaini yakaumbwa neHPMC mune inonamira inogona kupa imwe elastic kudzoreredza simba, iyo inoita basa rakakosha mukuramba kutsvedza kwetairi.

(3) Huwandu hweHPMC hunoshandiswa mune simende-based tile adhesives

Huwandu hweHPMC hwakawedzerwa hunowanzo kutsanangurwa zvinoenderana nezvinodiwa zvakasiyana zvekushandisa, kazhinji pakati pe0.1% ne0.5%.Mumashandisirwo chaiwo, zvinodikanwa kugadzirisa huwandu hunoenderana neiyo chaiyo fomula yekunamatira, mamiriro ekuvaka, uye mataira maratidziro kuti uwane yakanakisa mhedzisiro.Kuwedzera kushoma HPMC kunozokonzera kusabatana kwakashata, nepo kuwedzera yakawandisa kunogona kuwedzera mutengo uye kukanganisa kuita kwekuvaka.

(4) Kusarudzwa uye kuenderana kweHPMC

Kusarudza iyo yakakodzera HPMC yakatarwa mune simende-yakavakirwa mataira anonamira kwakakosha pakuita kwechigadzirwa.Maparamendi akadai seHPMC viscosity, substitution degree uye particle size inozokanganisa mhedzisiro yayo yekupedzisira.Kazhinji, iyo yakakwira viscosity yeHPMC, zviri nani kuchengetedza kwayo mvura uye kukora mhedzisiro, asi nguva yekuparara ichawedzerawo zvishoma.Naizvozvo, zvinodikanwa kuti usarudze zvakatemwa zvinoenderana nezvinodiwa chaizvo.

HPMC inoda kufananidzwa zvine mutsindo nezvimwe zvekuwedzera kuti uwane kuita kwakaringana.Semuyenzaniso, musanganiswa nezvinowedzerwa senge ethylene glycol, propylene glycol uye mamwe cellulose ethers zvinogona kuwedzera optimize mashandiro ekuvaka uye kusimba kwekunamira.

(5) Kuvandudza maitiro eHPMC mune simende-based tile adhesives

Nekuenderera mberi kwekufambira mberi kwehunyanzvi hwekuvaka, izvo zvinodikanwa zvekuita kwesamende-based tile adhesives zviri kuwedzera nekukwira.Seimwe yeakakosha ekuwedzera, maitiro ekusimudzira eHPMC anonyanya kuratidzwa mune zvinotevera zvinhu:

Tsvagiridzo nekuvandudza kwezvakatipoteredza HPMC: Nekuwedzera kwekuziva kwezvakatipoteredza, kutsvagisa uye kusimudzira kweyakaderera organic komisheni (VOC) uye inoshatisa inoshamwaridzana nharaunda HPMC yave tsika.

Kuvandudzwa kwekushanda kweHPMC: Kuti isangane nezvinodiwa zvekuvaka zvakasiyana, zvigadzirwa zveHPMC zvine mabasa chaiwo (senge anti-mildew, antibacterial, color retention, nezvimwewo) zvinogadzirwa kuti zvivandudze mashandiro akazara ematairi anonamira.

Kushandiswa kwehungwaru HPMC: Intelligent HPMC inogona kugadzirisa otomatiki kuita kwayo zvinoenderana nemamiriro ekunze (senge tembiricha, humidity, nezvimwewo), kuitira kuti simende-based tile adhesives inogona kuchengetedza kuita kwakanaka pasi pemamiriro akasiyana ekuvaka.

Kushandiswa kweHPMC mune simende-based tile adhesives inovandudza zvakanyanya mashandiro ezvinonamira, kusanganisira kuvandudza mashandiro ekuvaka, kuwedzera simba rekubatanidza, kuwedzera nguva yakavhurika uye kuwedzera anti-slip zvivakwa.Kuchengetwa kwayo kwemvura, kukora uye yakanaka interface inogonesa simende-yakavakirwa mataira anonamira kuti awane mamwe akanakisa mhedzisiro mukuvaka chaiko.Nekuenderera mberi kwekufambira mberi kwetekinoroji, nzvimbo dzekushandisa uye mabasa eHPMC ari kuramba achiwedzera, achipa tarisiro yakafara yekuvandudza simende-based tile adhesives.
