Izinto zokuncamathelisa iithayile zidlala indima ebalulekileyo kwishishini lokwakha ngenxa yokukwazi ukukhusela iithayile kwiindawo ezahlukeneyo, kubandakanya iindonga, imigangatho, kunye neetafile. Ukusebenza kwe-adhesive kunqunywe yimiba efana namandla ayo, ukuqina, ukuxhathisa kwamanzi kunye neempawu zokubambisana. Ngokuhamba kwexesha, kuba kubaluleke ngakumbi ukuphucula ukusebenza kwee-adhesives tile ukuhlangabezana neemfuno zokwakhiwa kwanamhlanje. Enye indlela yokufezekisa oku kukusebenzisa i-cellulose ethers.
I-cellulose ethers yiklasi ye-organic compounds ephuma kwi-cellulose, i-polymer yendalo efumaneka kwiindonga zeeseli zazo zonke izityalo. Ezi khompawundi ziyi-hydrophilic, zinyibilika emanzini, kwaye zisebenza kakhulu kumphezulu. Banoluhlu olubanzi lwezicelo kumashishini ahlukeneyo, kuquka ukwakhiwa, amayeza, amalaphu kunye neemveliso zokhathalelo lomntu.
Ukongeza i-cellulose ethers kwi-adhesives ye-tile kunokuphucula ukunamathela kunye neempawu ezidibeneyo, ngaloo ndlela kuphuculwe ukusebenza kwayo. Nazi ezinye iindlela i-cellulose ethers eziphucula ngayo ukusebenza kokuncamatheliswa kweethayile:
Ukwandisa ukugcinwa kwamanzi
Ipropati ebalulekileyo ye-adhesives tile kukugcinwa kwamanzi. I-adhesive ye-tile idinga ukugcina ukuhambelana kwayo kunye nokusebenza xa ibonakaliswe emanzini. Oku kungenxa yokuba amanzi anokuchaphazela kakhulu iimpawu zokuncamathelisa okuncamathelayo. Xa i-cellulose ethers yongezwa kwiifom ze-adhesive ze-tile, zandisa umthamo wokubambelela kwamanzi we-adhesive.
I-cellulose ethers isebenza njengeepolima ezinyibilikayo emanzini ezifunxa amanzi kwaye zenze into efana nejeli. Le nto efana nejeli isasaza amanzi ngokulinganayo kulo lonke umxube wokuncamathelisa, ukuqinisekisa ukuba i-adhesive ihlala isetyenziswa ixesha elide. Eli nqaku liphinda likhulise ixesha elivulekileyo lokubambelela, livumela ixesha elaneleyo lokuba i-tile ilungelelanise ngaphambi kokuba i-adhesive yome.
Ukuphucula amandla ebhondi
Amandla ebhondi ye-adhesive tile enye into ephambili emisela ukusebenza kwe-adhesive. Amandla ebhondi abhekisela kumandla afunekayo ukuze aphule ikhonkco phakathi kwe-adhesive kunye ne-substrate. Xa amandla ebhondi ephakamileyo, i-adhesive imelana noxinzelelo kunye ne-deformation, iqinisekisa ukuba i-tile ibambelele ngokuqinileyo kwi-substrate.
I-cellulose ethers inokuphucula amandla okudibanisa ama-adhesives e-tile ngokunyusa iimpawu zokuxhamla kwi-adhesive. Iimpawu zokubambelela kwi-adhesive zichongwa ngokukwazi kwayo ukunamathela kumphezulu we-substrate. Xa i-cellulose ethers yongezwa kwiindlela zokuncamathelisa iithayile, zenza indawo encangathi ephucula iimpawu zokuncamathelisa.
Ukwandisa ukuguquguquka
I-Flexibility yipropati ebalulekileyo ye-adhesives tile, ngakumbi xa ulungisa iileyile kwii-substrates ezifumana ukwanda kwe-thermal kunye nokucutha. Iisubstrates ezifana nekhonkrithi kunye neenkuni zinokukhubazeka kakhulu ngenxa yokutshintsha kwamaqondo obushushu, okubangela ukuqhekeka kweethayile kunye nokunamathiswa.
I-cellulose ethers inokusebenza njenge-plasticizers ukwandisa i-elasticity ye-adhesives, ngaloo ndlela iphucula ukuguquguquka kwee-adhesive tile ze-ceramic. I-Plasticizers yiikhompawundi ezandisa ukuguquguquka kwezinto ngokunciphisa amandla e-intermolecular abamba iimolekyuli kunye. Xa i-cellulose ethers yongezwa kwi-tile yokunamathisela kwi-adhesive formulations, yenza njengeplastiki, okwenza i-adhesive ibe yi-brittle kwaye ikhulise ukuqina kwayo. Le propati iphakamisa ukukwazi ukunamathela kwi-adhesive yokumelana noxinzelelo kunye ne-deformation, iqinisekisa ukuba iileyili zibambelela ngokuqinileyo kwi-substrate.
Ukuphucula ukusebenza
Ukusebenza kwesicelo se-adhesive tile luphawu olubalulekileyo olumisela ukukhululeka kokusetyenziswa kwe-adhesive ngexesha lokusetyenziswa. Xa usebenzisa i-adhesive tile, umxube wokubambelela kufuneka ube nokuhambelana okuchanekileyo, i-viscosity kunye neempawu zokuhamba. Oku kuqinisekisa ukuba i-adhesive isasazwa ngokulinganayo kwi-substrate, ivumela iileyili ukuba zihambelane ngokufanelekileyo.
I-cellulose ethers inokusebenza njenge-thickeners kunye ne-rheology modifiers ukuphucula ukusebenza kwe-adhesives tile. I-Thickeners yi-compounds eyandisa i-viscosity yesisombululo, ngelixa i-rheology modifiers zikhompawundi ezitshintsha iimpawu zokuhamba kwamanzi. Xa i-cellulose ethers yongezwa kwi-tile adhesive formulations, yandisa i-viscosity yomxube we-adhesive, ukuqinisekisa ukuba i-adhesive isasazeka ngokulinganayo kwi-substrate. Le propati iphinda ikhulise ukusebenza kwe-adhesive, okwenza kube lula ukufaka kunye nokulungelelanisa iithayile.
ukuququmbela
I-cellulose ethers ibonakaliswe ukuphucula kakhulu ukusebenza kwe-adhesives tile. Njengoko imfuno ye-adhesives tile adhesives high-performance iyaqhubeka ikhula, ukufakwa kwe-cellulose ethers kwi-tile adhesive formulations kubaluleke kakhulu. Ukusetyenziswa kwe-cellulose ethers kwi-adhesives ye-tile kuphucula ukugcinwa kwamanzi kwe-adhesive, amandla ebhondi, ukuguquguquka kunye nokusebenza. Ezi zakhiwo ziqinisekisa ukuba i-adhesive inokumelana noxinzelelo kunye nokuguqulwa, ukubonelela ukulungiswa okuthembekileyo kweetayile kwiintlobo ezahlukeneyo ze-substrates.
