Yintoni umsebenzi we-cellulose kwi-adhesive tile?

I-adhesives ye-tile ibaluleke kakhulu ekwakhiweni nasekuhlaziyeni, ukubonelela ngebhondi phakathi kweetayile kunye ne-substrate. Ezi zincamathelisi kufuneka zibonise uluhlu lweempawu, kubandakanya ukusebenza, ukugcinwa kwamanzi, kunye namandla okubambelela. Enye yezinto eziphambili eziphucula ezi mpawu ziphuma kwi-cellulose. I-Cellulose, i-polymer yendalo efunyenwe kwiindonga zeeseli zezityalo, iguqulwa ngamakhemikhali ukuze ivelise izinto ezifana ne-methyl cellulose (MC) kunye ne-hydroxypropyl methylcellulose (HPMC), esetyenziswa kakhulu kwi-adhesives tile.

Iipropati zeCellulose Derivatives

I-cellulose derivatives esetyenziswa kwi-adhesives yethayile ngokuyintloko ziipolima ezinyibilikayo emanzini ezibonisa iimpawu ezizodwa:

Ukugcinwa kwamanzi: Bangakwazi ukubamba amanzi amaninzi, okubalulekileyo kwinkqubo yokunyanga i-adhesive.

I-Agent yokutyebisa: Bandisa i-viscosity yomxube wokunamathela, ukuqinisekisa ukusetyenziswa okufanelekileyo kunye nokunciphisa i-sagging.

Ukwenziwa kweFilimu: Benza ifilimu ebhityileyo xa yomiswe, enegalelo kumandla ebhondi kunye nokuguquguquka kokuncamathelisa.

Ukuguqulwa kwe-Rheology: Baguqula iimpawu zokuhamba kwe-adhesive, ukuphucula ukusebenza kwayo kunye nokulula kwesicelo.

Imisebenzi yeCellulose kwi-Tile Adhesive

1. Ukugcinwa kwamanzi

Omnye wemisebenzi ephambili ye-cellulose derivatives kwi-adhesive tile kukugcinwa kwamanzi. Ngethuba lenkqubo yokunyanga i-sement-based adhesives, ubukho bamanzi aneleyo buyimfuneko kwi-hydration reaction. I-cellulose derivatives ifunxa kwaye igcine amanzi, ngokuthe ngcembe iwakhulula ukuqinisekisa ukugcwala okupheleleyo. Oku kukhutshwa kwamanzi okulawulwayo kuphucula amandla kunye nokuqina kwe-adhesive bond.

Ukuphuculwa Konyango: Ngokugcina amanzi, i-cellulose derivatives ikhusela ukomisa kwangaphambi kwexesha, oku kunokukhokelela ekunyangeni okungaphelelanga kunye neebhondi ezibuthathaka.

Ixesha elongeziweyo lokuvula: I-adhesive ihlala isebenza ixesha elide, ivumela ukulungiswa ngexesha lokubekwa kwe-tile.

2. Ukomelezwa kokuSebenza

I-cellulose derivatives iphucula ukusebenza kwe-adhesives tile ngokuguqula iimpawu zabo ze-rheological. Umxube we-adhesive uba ngokubambisana kwaye kulula ukusabalalisa, ukunciphisa umgudu kunye nexesha ngexesha lokusetyenziswa.

Isicelo esigudileyo: Ukwanda kwe-viscosity kuthintela ukuwohloka kunye nokudilika, ngakumbi kwiindawo ezithe nkqo.

I-Coverage ephuculweyo: I-adhesive isasazeka ngokufanayo, iqinisekisa ukugubungela okupheleleyo kunye nokubambelela okungcono.

3. Ukuphuculwa kokuncamathela

I-cellulose derivatives inegalelo kwiimpawu zokubambelela kwii-tile zokunamathisela. Ikhono lokwenza ifilimu yala ma-polymers liqinisekisa ukudibanisa okuqinileyo phakathi kwe-tile kunye ne-substrate.

Amandla eBond: Ifilimu ebhityileyo eyenziwe yi-cellulose derivatives iphucula i-mechanical interlocking kunye ne-adhesive bond bond.

Ukuguquguquka: I-adhesive ihlala iguquguqukayo, ihambisa ukunyakaza okuncinci kunye nokunciphisa umngcipheko wokuchithwa kwe-tile.

4. Iarhente yokutyebisa

Njengee-agent ezityebisayo, i-cellulose derivatives yandisa i-viscosity ye-adhesives tile. Oku kubaluleke kakhulu ekugcineni ukuhambelana okufanelekileyo kunye nokuzinza komxube wokunamathela.

Ukuhambelana: Umxube onamathele oqiniweyo uhlala u-homogenous, ukuthintela ukuhlukana kwamacandelo.

Ukuzinza: Ukunyuka kwe-viscosity kunciphisa amathuba okuba i-adhesive iqhube okanye ithontsize, iyenze ifaneleke kuzo zombini izicelo ezithe tye kunye nezithe nkqo.

5. Ukumelana ne-Sag

Kwizicelo ezibandakanya umphezulu othe nkqo, njengokufakela iithayili eludongeni, ukuxhathisa kwe-sag kubalulekile. I-cellulose derivatives iphakamisa ukuxhathisa kwe-sag ye-adhesives tile, iqinisekisa ukuba iileyili zihlala kwindawo ngexesha nangemva kokusetyenziswa.

Izicelo eziNqobileyo: I-adhesive ihlala kwindawo ngaphandle kokuslayida phantsi, inikezela ukubamba okuqinileyo kokuqala kunye nokunciphisa imfuno yokuxhaswa komatshini.

Ubukhulu obufanayo: I-adhesive igcina ubukhulu obuhambelanayo, buyimfuneko ekufezekiseni umgangatho olinganayo kunye nomgangatho wethayile.

6. Ixesha eliVulekileyo eliPhuculweyo kunye noLungiso

I-Cellulose derivatives yandisa ixesha elivulekileyo lokunamathelisa i-tile, ixesha apho iileyili zinokulungiswa ngaphandle kokuphazamisa amandla okubambisana. Oku kuluncedo ngakumbi kwiiprojekthi ezinkulu apho ukubekwa ngokuchanekileyo kuyimfuneko.

Ukulungelelaniswa: Ixesha elide elivulekileyo livumela ukubekwa ngokutsha kweethayile ukuqinisekisa ukulungelelaniswa okufanelekileyo kunye nezithuba.

Inkunkuma eNcitshisiweyo: I-adhesive ayibeki ngokukhawuleza, ukunciphisa inkunkuma kunye nokuqinisekisa ukusetyenziswa kakuhle kwezinto.

Iintlobo zeCellulose Derivatives ezisetyenziswa kwi-Tile Adhesive

Iindidi ezininzi ze-cellulose derivatives ziqhele ukusetyenziswa kwii-adhesives zethayile, nganye ibonelela ngeenzuzo ezithile:
