Umphumela we-cellulose ether on tile anamathela

Ukunamathela okususelwa kusimende okwamanje kuyinto enkulu kunazo zonke yodaka olukhethekile oluhlanganisiwe, oluhlanganiswa ngosimende njengezinto eziphambili ze-cementle Ngokuvamile, kudinga kuphela ukuhlanganiswa namanzi lapho kusetshenziswa. Uma kuqhathaniswa nodaka olujwayelekile kasimende, lungathuthukisa kakhulu amandla abugqilayo phakathi kwezinto ezibhekene ne-substrate, futhi inokumelana okuhle kwamasheya nokuphikiswa kwamanzi okuhle nokuphikiswa kwamanzi. Kanye nezinzuzo zokuphikiswa komjikelezo we-freeze-thaw, okusetshenziselwa ukunamathisela amathayela angaphakathi nangaphandle, amathayela aphansi nezinye izinto zokuhlobisa, okwamanje, njengamakhishi wokuhlobisa ama-cele asetshenziswa kakhulu.

Imvamisa lapho sikwahlulela ukusebenza kwe-tile anamathela, asinakunaka kuphela ukusebenza kwaso okusebenzayo kanye nekhono lokulwa nokulwa, kepha nalondela amandla alo okuvulwa kanye nesikhathi sokuvula. I-Cellulose Ether in Tile Adhesive ayithintanga kuphela izakhiwo ze-Rheological of Porcelain Adhesive, njengokusebenza okubushelelezi, njll.

1. Amahora okuvula
Lapho i-rubber powder kanye ne-cellulose ether co-ekhona ngodaka olumanzi, amanye amamodeli wedatha akhombisa ukuthi i-reabber powder inamandla okunamathisela imikhiqizo ye-celtetic hydration, futhi i-cellulose ether ikhona ngaphezulu ku-interstitial fluid, okuthinta ukubonakala kwesibhamu esithe xaxa nesikhathi sokusetha isikhathi. Ukungezwani kwe-cellulose ether kukhulu kunalokho kwe-powder yerabha, kanye ne-cellulose ether ecebiselwe esibonakalayo sodumo kuzosiza ekubumbeni amabhondi e-hydrogen phakathi kwendawo eyisisekelo kanye ne-cellulose ether.

Ku-datar omanzi, amanzi asosimende athuthumela, kanti ama-cellulose ether ayacekelwa phansi ebusweni, futhi ifilimu lizokwakhiwa ebusweni bodaka ngaphansi kweminyaka emi-5, kanti amafilimu asuswa engxenyeni engaphansi kodaka, futhi amafilimu asuswa ekuqaleni, futhi ukufuduka kwamanzi kuzoletha okuningi ukucebisa isendlalelo endaweni yodaka.

Ukwakheka kwefilimu kwe-cellulose ether ngaphezulu kodaka kunethonya elikhulu ekusebenzeni kodaka:

1. Ifilimu elakhiwe lincane kakhulu futhi lizoncibilika kabili, alikwazi ukuncibilika ukuhwamuka kwamanzi futhi linciphise amandla.

2. Ifilimu elakhiwe likhulu kakhulu. Ukuqoqwa kwe-cellulose ether ku-uketshezi oluphakathi kodaka kuphakeme futhi i-viscosity iphakeme. Akulula ukwephula ifilimu engaphezulu lapho amathayili enamathiselwe.

Kungabonakala ukuthi izakhiwo ezakha amafilimu ze-cellulose ether zinomthelela omkhulu esikhathini esivulekile. Uhlobo lwe-cellulose ether (HPMC, i-hemc, i-MC, njll.) Futhi izinga lokuthezeka (ukufakwa esikhundleni) lithinta ngqo izakhiwo ezenziwayo ze-cellulose ether, kanye nobulukhuni befilimu.
