I-starch ether ku-mortar

I-starch ether Yenza ungqimba lwe-mortar, wandise ukumelana nokuwa, ukumelana nokuwa kanye ne-rheology ye-mortar

Isibonelo, ekwakhiweni kwe-tile glue, i-putty, kanye ne-plastering mortar, ikakhulukazi manje njengoba ukufutha ngomshini kudinga ukugeleza okuphezulu, isibonelo, kubaluleke kakhulu ku-gypsum-based mortar (i-plaster efuthwe ngomshini idinga ukugeleza okuphezulu kodwa izobangela isenzakalo esibi sokuwa, i-starch Ether ingakwazi ukulungisa lesi sici).

Ukumelana noketshezi kanye nokuwa kuvame ukuphikisana, futhi ukwanda kokuwa kuzoletha ukwehla kokumelana nokuwa. Udaka olunezakhiwo ze-rheological lungaxazulula kahle ukuphikisana kokuthi lapho kusetshenziswa amandla angaphandle, i-viscosity iyancipha, okuthuthukisa ukusebenza kahle kanye nokumpompa, futhi lapho amandla angaphandle ehoxiswa, i-viscosity iyanda futhi ithuthukise ukumelana nokuwa.

Ngenxa yendlela yamanje yokwandisa indawo yethayela, ukwengeza i-starch ether kungathuthukisa ukumelana kokushelela kwe-adhesive yethayela.

2) Nweba amahora okuvula

Kuma-adhesive ethayela, ingahlangabezana nezidingo zama-adhesive ethayela akhethekile ngesikhathi sokuvula eside (Isigaba E, sinwebeka kusukela kumaminithi angu-20 kuya kwangu-30 ukuze sifinyelele ku-0.5MPa).

a. Ukuthuthukiswa kokusebenza komphezulu

I-starch ether ingenza ubuso bodaka olusekelwe ku-gypsum kanye nolwesimende bube bushelelezi, kube lula ukubusebenzisa, futhi bunomphumela omuhle wokuhlobisa. Kubaluleke kakhulu kuma-mortar asekelwe ku-plaster kanye nama-mortar ahlotshiswe ngongqimba oluncane njenge-putty.

b. Indlela yokusebenza kwe-starch ether

Uma i-starch ether incibilikiswa emanzini, izohlakazeka ngokulinganayo ohlelweni lwe-cement mortar. Ngenxa yokuthi ama-molecule e-starch ether anesakhiwo senethiwekhi futhi ashajwa kabi, azomunca izinhlayiya ze-cement ezishajwe kahle, ezingasetshenziswa njengebhuloho lokushintsha ukuxhuma i-cement, ngaleyo ndlela zinikeze Uma inani elikhulu lesivuno se-slurry lingathuthukisa umphumela wokulwa nokugoba noma wokungasheleli.
