Indima yeepolymers ezihlaziywayo kunye neselulosi kwii-adhesives tile

I-adhesives ye-tile idlala indima ephambili kwishishini lokwakha, inika izisombululo ezihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala khona. Ukusebenza kwee-adhesives tile kuxhomekeke kakhulu kumxholo wezongezo eziphambili, apho i-polymers e-dispersible kunye ne-cellulose zimbini izithako eziphambili.

1. Iipholima eziphinde zihlakazwe kwakhona:

1.1 Inkcazo kunye neepropati:
Iipolymers ezihlaziywayo zizongezo zomgubo ezifunyenwe ngokutshiza i-emulsions ye-polymer okanye i-dispersions. Ezi polima zihlala zisekelwe kwi-vinyl acetate, i-ethylene, i-acrylics okanye ezinye ii-copolymers. Ifom yepowder ilula ukuyiphatha kwaye ingabandakanywa kwiifom ze-adhesive ze-tile.

1.2 Nyusa ukuncamathela:
Iipolymers ezihlaziywayo ziphucula ngokuphawulekayo ukubambelela kweetayile zokubambelela kwiintlobo ezahlukeneyo ze-substrates. I-polymer iyoma ukuze yenze ifilimu eguquguqukayo, enamathele eyenza ibhondi eqinile phakathi kwe-adhesive kunye ne-tile kunye ne-substrate. Oku kubambelela okuphuculweyo kubalulekile ekuqinisekiseni ixesha elide kunye nokuzinza kwendawo yethayile.

1.3 Ukuguquguquka kunye nokumelana nokuqhekeka:
Ukongezwa kwepolymer edibeneyo kunika ukuguquguquka kwe-adhesive tile, evumela ukuba ihambelane nokunyakaza kwe-substrate ngaphandle kokuqhekeka. Oku kuguquguquka kubaluleke kakhulu kwiindawo apho utshintsho lweqondo lokushisa okanye utshintsho lwesakhiwo lunokuthi lwenzeke, ukuthintela ukubunjwa kweentanda ezinokuthi ziphazamise ingqibelelo yendawo ye-tile.

1.4 Ukumelana namanzi:
Iipolymers ezihlaziywayo zifaka isandla ekuxhathiseni kwamanzi kwi-adhesives tile. Ifilimu ye-polymer eyenza njengoko yomile isebenza njengesithintelo, ikhusela amanzi ekungeneni kwaye ngaloo ndlela ikhusela ibhondi. Oku kubaluleke ngakumbi kwiindawo ezifumileyo ezifana namagumbi okuhlambela kunye namakhitshi, apho amanqanaba okufuma aphezulu.

1.5 Ukwakhiwa kunye neeyure zokuvula:
Iimpawu ze-rheological ze-polymers eziphinda zenziwe kwakhona zidlala indima ebalulekileyo ekusebenzeni kwe-adhesives tile. Banceda ukugcina ukuhambelana okufanelekileyo kunye nokuqinisekisa ukusetyenziswa okulula. Ukongeza, i-polymer ephinda ihlaziywe inceda ukwandisa ixesha elivulekileyo lokuncamathelisa, inika abafakeli ixesha elaneleyo lokulungelelanisa indawo yethayile phambi kweeseti zokuncamathelisa.

2. ISelulosi:

2.1 Inkcazo kunye neendidi:
I-Cellulose yipolymer yendalo ephuma kwiindonga zeeseli zezityalo kwaye isoloko isetyenziswa njengesongezo kwi-adhesives tile. I-cellulose ethers, efana ne-methylcellulose (MC) kunye ne-hydroxyethylcellulose (HEC), isetyenziswa rhoqo ngenxa yokugcinwa kwamanzi okugqwesileyo kunye neempawu zokuqina.

2.2 Ukugcinwa kwamanzi:
Omnye wemisebenzi ephambili ye-cellulose kwi-adhesives ye-tile kukukwazi ukugcina amanzi. Olu phawu lwandisa ixesha elivulekileyo lokuncamathelisa, ngaloo ndlela ukwandisa ukuqhubekeka. Xa i-cellulose ithatha amanzi, yenza i-gel-efana nesakhiwo esithintela i-adhesive ukuba yome ngokukhawuleza ngexesha lokusetyenziswa.

2.3 Phucula ukuqhubekeka kunye nokumelana ne-sag:
I-Cellulose iphucula ukusebenza kwe-adhesive ye-tile ngokuthintela ukugoba ngexesha lokusetyenziswa ngokuthe nkqo. Umphumo wokuqina we-cellulose unceda i-adhesive igcine imilo yayo eludongeni, iqinisekisa ukuba iileyili zihambelana ngokulinganayo ngaphandle kokuwa.

2.4 Nciphisa ukushwabana:
I-cellulose inokunciphisa i-shrinkage ye-adhesive tile ngexesha lokumisa. Oku kubaluleke kakhulu kuba ukucutheka okugqithisileyo kunokukhokelela ekwenziweni kwe-voids kunye nokuqhekeka, ukuphazamisa ingqibelelo yonke yebhondi.

2.5 Ifuthe kumandla okuqina:
Izinto zokuncamathelisa iithayile zineselulosi ukunyusa amandla azo okuqina. Oku kubaluleke kakhulu kwiindawo eziphantsi kwemithwalo enzima okanye uxinzelelo, njengoko igalelo ekuhlala kuyo yonke into kunye nokusebenza komphezulu we-tile.

3. Impembelelo ye-Synergistic ye-polymer ephinda ihlakazwe kunye neselulosi:

3.1 Ukuhambelana:
Iipolymers ezihlaziywayo kunye ne-cellulose zihlala zikhethwa ngokuhambelana kwazo kunye nezinye izithako ekubunjweni kwe-adhesive tile. Oku kuhambelana kuqinisekisa umxube we-homogeneous owandisa iinzuzo zesongezo ngasinye.

3.2 Indibaniselwano yentsebenziswano:
Ukudityaniswa kwepolymer edispersible kunye ne-cellulose ivelisa umphumo we-synergistic kwi-bonding. Iifilimu eziguquguqukayo ezenziwe kwi-polymers eziphinda ziphinde zenziwe zincedisana nokugcinwa kwamanzi kunye neempawu ezityebisayo ze-cellulose, ezikhokelela kwi-adhesive eyomeleleyo, ehlala ixesha elide kunye nesebenzayo.

3.3 Ukusebenza okuphuculweyo:
I-polymer edibeneyo kunye ne-cellulose edibeneyo iphucula ukusebenza ngokubanzi kwe-adhesive tile, inikezela ukunamathela okungcono, ukuguquguquka, ukuchasana kwamanzi, ukuqhutyelwa phambili kunye nokuqina. Olu luhlu lunenzuzo ngakumbi kwaye luyimfuneko kwizicelo ezifuna ukuxhamla okuthembekileyo kunye nexesha elide.

Ukubandakanya iipolymers eziphinda zihlakazwe kunye neselulosi kwi-adhesives ye-tile yinkqubo ecwangcisiweyo kwaye eqinisekisiweyo kwishishini lokwakha. Ezi zongezo zidlala indima ephambili ekwandiseni ukubambelela, ukuguquguquka, ukuxhathisa kwamanzi, ukuqhubekeka kunye nokuqina kwexesha elide. I-synergy phakathi kweepolymers eziphinda zihlakazwe kunye ne-cellulose iphumela kwi-balanced adhesive formulations ehlangabezana neemfuno ezifunekayo zeeprojekthi zokwakha zanamhlanje. Njengoko iteknoloji kunye nophando luqhubeka luqhubela phambili, ezinye izinto ezintsha kwindawo yokubambelela kwi-tile kulindeleke ukuba zenzeke, ngokugxininisa ngokuqhubekayo ekuphuculeni ukusebenza kunye nokuzinza kwezi zixhobo zokwakha ezibalulekileyo.
