I-cellulose ether, eyaziwa ngokuba yi-methylcellulose / hydroxypropylmethylcellulose (HPMC / MHEC), i-polymer e-soluble yamanzi esetyenziswa ngokubanzi kwizicelo zokwakha. Ineempawu ezininzi ezibalulekileyo eziyenza ibe yimathiriyeli ekrwada ebalulekileyo ekwenzeni udaka kunye nesamente. Iimpawu ezikhethekileyo ze-cellulose ethers zibandakanya ukugcinwa kwamanzi, ukunamathela kakuhle, kunye nokukwazi ukwenza njengama-thickeners.
I-cellulose ethers yonyusa amandla ebhondi yodaka ngokubonelela ngokuguquguquka kunye nokunwebeka kumxube wodaka. Ngenxa yoko, izinto eziphathekayo ziba lula ukusebenza kunye nemveliso yokuphela ihlala ixesha elide. Eli nqaku liza kuhlolisisa indlela i-cellulose ethers (HPMC / MHEC) echaphazela ngayo amandla e-bond of mortars.
Isiphumo se-cellulose ether kudaka
I-cellulose ethers zizithako eziphambili kwizinto ezininzi zokwakha, kuquka udaka kunye nesamente. Xa isetyenziselwa udaka, i-cellulose ether isebenza njenge-binder, inceda ukubopha umxube kunye nokuphucula ukusebenza kwezinto. Iipropati zokugcina amanzi ze-cellulose ethers zibonelela ngeemeko ezifanelekileyo zokunyangwa ngokufanelekileyo kwee-mortars kunye neesimenti, ngelixa ukunamathela kakuhle kunceda ukwenza ibhondi eqinile phakathi kwamacandelo ahlukeneyo.
Udaka sisixhobo sokwakha esibalulekileyo esisetyenziselwa ukuncamathelisa izitena okanye iibhloko. Umgangatho webhondi uchaphazela amandla kunye nokuqina kwesakhiwo. Ukongezelela, amandla ebhondi yipropati ebalulekileyo yokuqinisekisa ukuba isakhiwo sinokumelana nazo zonke iimeko eziphantsi kwayo. Amandla ebhondi yodaka abaluleke kakhulu kuba isakhiwo esiphantsi koxinzelelo okanye umthwalo sixhomekeke kakhulu kumgangatho webhondi wodaka. Ukuba amandla ebhondi awanelanga, isakhiwo sixhomekeke kwiingxaki ezinkulu ezifana nokuqhekeka okanye ukungaphumeleli, okubangelwa iingozi ezingalindelekanga, ukunyuka kweendleko zokugcina kunye neengozi zokhuseleko.
Indlela yokusebenza ye-cellulose ethers
I-cellulose ether yipolymer enyibilikayo emanzini esetyenziselwa ukuphucula iimpawu zodaka. Indlela yokusebenza ye-cellulose ether kumdaka kukusasazeka kwezongezo, ezilungele kakhulu iipolima ezinyibilikayo zamanzi, kwaye ziphucula amandla ezinto ngokunciphisa ukuxinana komphezulu wezinto. Oku kuthetha ukuba xa i-cellulose ether yongezwa kudaka, isasazwe ngokulinganayo kuwo wonke umxube, ukuthintela ukubunjwa kwamaqhuma anokubangela amabala abuthathaka kwibhondi yodaka.
I-ether ye-cellulose iphinda isebenze njenge-arhente yokuqina kwi-mortar, idala umxube we-viscous ovumela ukuba ubambelele ngokuqinileyo kwisitena okanye ibhloko esetyenziswa kuyo. Ukongeza, iphucula umthamo womoya kwaye iphucula ukusebenza kodaka ukuze isebenze ngokufanelekileyo kunye nokwanda kokulula kokusetyenziswa. I-cellulose ethers ezongeziweyo kudaka zicotha isantya apho amanzi akumxube aphuphumayo, nto leyo eyenza udaka lube lula ukusebenzisa kunye nokudibanisa amacandelo kunye ngamandla ngakumbi.
Izinto eziluncedo ze-cellulose ether kumdaka
Ukongezwa kwe-cellulose ethers (HPMC / MHEC) kwiifama kuneenzuzo ezininzi ezibandakanya ukuphuculwa kwamandla ebhondi. Amandla ebhondi aphezulu anyusa ukuqina kwexesha elide lesakhiwo, ukuphepha ukulungiswa kweendleko.
I-ethers ye-cellulose iphinda ibonelele ngokusebenza ngcono kumdaka, okwenza kube lula ukwakha kunye nokunciphisa ixesha elifunekayo kwimisebenzi enzima kakhulu. Oku kuphucula ukusebenza kunceda ukwandisa isantya kunye nokusebenza kakuhle, ngaloo ndlela kwandisa imveliso kushishino lokwakha.
I-ether ye-cellulose inokuphucula ukusebenza kokugcinwa kwamanzi kwi-mortar kunye nokuqinisekisa ixesha elaneleyo lokunyanga okuzinzileyo. Oku kwandisa ukudibanisa kwezinto ezisetyenziselwa ukwakhiwa, okukhokelela kwisakhiwo esomelele ngakumbi.
I-cellulose ether additive mortars kulula ukuyicoca, kwaye ukususa izinto ezingaphezulu kwisakhiwo esigqityiweyo akunzima. Ukunyuka kokubambelela kodaka kwizinto zokwakha kuthetha inkunkuma encinci ngenxa yokuba umxube awuyi kuphazamiseka okanye ukhulule kwisakhiwo ngexesha lenkqubo yokulinganisa.
ukuququmbela
Ukongezwa kwe-cellulose ethers (HPMC / MHEC) kwi-mortars idlala indima ebalulekileyo ekuphuculeni amandla ebhondi yodaka lwezicelo zokwakha. I-cellulose ethers ibonelela ngokugcinwa kwamanzi, iphucula ukusebenza kodaka, kwaye ivumela isantya esicothayo sokunyuka komphunga ukwenzela ukudibanisa izinto ezingcono. Ukonyuka kwamandla ebhondi kuqinisekisa ukuqina kwesakhiwo, ukunciphisa imiba yokugcina engalindelekanga, ukuphucula ukhuseleko kunye nokunciphisa iindleko zokwakha. Ukuqwalasela zonke ezi nzuzo, kuyacaca ukuba ukusetyenziswa kwe-cellulose ethers kufuneka kwamkelwe ngokubanzi kwishishini lokwakha umgangatho ongcono kunye neeprojekthi zokwakha eziqinileyo.
