Ukuphucula ukusebenza kwe-putty kunye ne-gypsum cement usebenzisa i-MHEC

I-Putty kunye ne-plaster zizinto ezidumileyo ezisetyenziswa ngokubanzi kwishishini lokwakha. Ziyimfuneko ekulungiseleleni iindonga kunye neesilingi zokupeyinta, ukuvala iintanda, ukulungisa iindawo ezonakeleyo, kunye nokudala umphezulu ogudileyo, olinganayo. Ziqulunqwe ngezithako ezahlukeneyo ezibandakanya isamente, isanti, ikalika kunye nezinye izongezo ukubonelela ukusebenza okufunekayo kunye neempawu. I-Methylhydroxyethylcellulose (MHEC) yenye yezongezo eziphambili ezisetyenziselwa ukuveliswa kwe-putty kunye ne-plaster powder. Isetyenziselwa ukuphucula iimpawu ze powders, ukuphucula iimpawu zabo zokusebenza kunye nokwandisa izicelo zabo.

Izibonelelo zokusebenzisa i-MHEC ukuvelisa i-putty kunye ne-gypsum powder

I-MHEC ivela kwi-cellulose kwaye iveliswa ngenkqubo yokuguqulwa kweekhemikhali. Yikhompawundi enyibilikayo yamanzi esetyenziswa ngokubanzi njenge-thickener, stabilizer kunye ne-emulsifier kushishino lokwakha. Xa ifakwe kwi-putty kunye ne-gypsum powders, i-MHEC igubungela amaqhekeza, inika uluhlu olukhuselayo olubavimbela ukuba badibanise kwaye bahlale. Oku kuvelisa umxube othe kratya, ongaguquguqukiyo ekulula ukusebenza ngawo kwaye unike ukugqitywa okungcono.

Enye yeenzuzo eziphambili zokusebenzisa i-MHEC kwii-putty kunye ne-plasters kukuba iphakamisa iimpawu zabo zokugcina amanzi. I-MHEC ifunxa kwaye igcina umswakama, iqinisekisa ukuba umxube uhlala usetyenziswa kwaye awumi ngokukhawuleza. Oku kubaluleke kakhulu kwiindawo ezishushu nezomileyo apho umxube ukhawuleza ungasebenzi, okukhokelela ekugqityweni kokuphazamiseka.

I-MHEC iphinda iphucule ukusebenza kunye nexesha lokusebenza kweeputty kunye ne-plasters. I-MHEC yenza ukuxuba kunye nokusebenzisa umxube lula ngokugcina ukufuma kunye nokuthintela umxube ukuba wome. Ukongeza, i-MHEC's smooth, i-buttery texture ivumela i-putty kunye ne-stucco ukuba isasazeke ngokulinganayo phezu komhlaba ngaphandle kokushiya amaqhuma okanye i-clumps, iqinisekisa ukugqiba okungenasici, okuhle.

Ukongeza ekuphuculeni ukuthungwa kunye nokusebenza kwee-putty kunye ne-plasters, i-MHEC inokuphucula iimpawu zabo zokudibanisa. Ngokwenza umaleko okhuselayo ojikeleze amasuntswana, i-MHEC iqinisekisa ukuba badibanisa ngcono kwindawo abayiphathayo. Oku kukhokelela kwindawo eyomeleleyo, eyomelele ngakumbi ekungenakwenzeka ukuba iqhekeke, iqhekeke okanye ixobuke ngokuhamba kwexesha.

Enye inzuzo ebalulekileyo yokusebenzisa i-MHEC kwi-putty kunye ne-plaster kukuba kwandisa ukuchasana kwabo emoyeni kunye nomswakama. Oku kuthetha ukuba xa i-putty okanye i-stucco isetyenzisiwe, iya kuxhathisa umonakalo ovela emoyeni kunye nokufuma, ukuqinisekisa ukuba umphezulu uhlala uhleli kwaye uhle ixesha elide.

Ukuphucula ukusebenza kwePutty kunye neGypsum usebenzisa i-MHEC

Ukwandisa ukusebenza kwe-putty kunye ne-plaster powder, kubalulekile ukuqinisekisa ukuba i-MHEC isetyenziswe kwimilinganiselo echanekileyo. Oku kuthetha ukuba ukusebenzisa inani elichanekileyo le-MHEC kunokufezekisa ukusebenza okufunwayo kunye neempawu ze-putty okanye i-stucco eveliswayo.

Izinto ezisingqongileyo ezinokuchaphazela ukusebenza kwe-putty kunye ne-gypsum powder kufuneka ziqwalaselwe. Ngokomzekelo, kwiindawo ezishushu nezomileyo, i-MHEC eninzi ingadinga ukufakwa ukuqinisekisa ukuba umxube uhlala usebenza kwaye uhambelana.

Kubalulekile ukuqinisekisa ukuba i-putty okanye istucco isetyenziswe ngokuchanekileyo ukunyusa ukusebenza kwayo. Oku kuthetha ukulandela imiyalelo yomenzi ngononophelo kwaye uqinisekise ukuba umxube uxutywe kakuhle phambi kokusetyenziswa. Ukongezelela, izixhobo ezikhethekileyo zingafuneka ukuqinisekisa ukuba i-putty okanye i-stucco isetyenziswe ngokulinganayo kwaye ngokuqhubekayo kwindawo ephathwayo.

I-MHEC iyongezo ebalulekileyo esetyenziselwa ukuveliswa kwe-putty kunye ne-plaster powder. Iphucula iipropati kunye neempawu zezi zinto, ukuphucula ukuqhutyelwa kwazo, ukugcinwa kwamanzi, ukunamathela kunye nokuchasana nomoya kunye nokufuma. Oku kubangela ukugqiba okungaguquguqukiyo, okuhlala ixesha elide kunye nokukhangayo okungenakufane kwenzeke ukuqhekeka, ukukrazula okanye ukuxobula ngokuhamba kwexesha. Ukuze kulungiswe ukusebenza kwe-putty kunye ne-gypsum powder, kubalulekile ukuqinisekisa ukuba i-dosage echanekileyo ye-MHEC isetyenzisiweyo, ngokuqwalasela izinto ezisingqongileyo ezinokuchaphazela ukusebenza kwazo. Ukongezelela, kubalulekile ukusebenzisa i-putty okanye i-stucco ngokuchanekileyo ukwandisa ukusebenza kwayo kunye nokufezekisa iziphumo ezifunwayo.

I-HEMC isetyenziselwa ukwakhiwa kwesamente ukuphucula iimpawu zayo I-Hydroxyethyl methylcellulose (HEMC) yikhemikhali esetyenziswa kakhulu kwishishini lokwakha. Lunxulumano phakathi kokusebenza, ukugcinwa kwamanzi, ithixotropy, njl.njl. Kule mihla, uhlobo olutsha lwe-cellulose ether lufumana ingqalelo engakumbi nangakumbi. Yintoni eye yatsala ingqalelo ngakumbi yi-hydroxyethyl methylcellulose (MHEC).

Enye yezona zinto zibalulekileyo ezimisela umgangatho weemveliso zesamente kukusebenza komxube. Yiloo ndlela ilula ngayo isamente ukuxuba, ukumila kunye nendawo. Ukufezekisa oku, umxube wesamente kufuneka ube lulwelo olwaneleyo lokugalela kwaye uhambe lula, kodwa kufuneka ube ne-viscous ngokwaneleyo ukubamba ukumila kwawo. I-MHEC inokufezekisa le propati ngokunyusa i-viscosity ye-samente, ngaloo ndlela iphucula ukusebenza kwayo.

I-MHEC inokukhawulezisa i-hydration yesamente kunye nokuphucula amandla ayo. Amandla okugqibela esamente axhomekeke kubungakanani bamanzi asetyenzisiweyo ukuyixuba. Amanzi amaninzi aya kunciphisa amandla e-samente, ngelixa amanzi amancinci kakhulu aya kwenza kube nzima kakhulu ukusebenza. I-MHEC inceda ukugcina umlinganiselo othile wamanzi, ngaloo ndlela iqinisekisa i-hydration efanelekileyo ye-samente kunye nokukhuthaza ukubunjwa kwezibophelelo ezinamandla phakathi kweengqungquthela zesamente.

I-MHEC inceda ukunciphisa inani leentanda zesamente. Njengoko i-samente iphilisa, umxube uyancipha, onokukhokelela ekubunjweni kokuqhekeka ukuba i-shrinkage ayilawulwa. I-MHEC ikhusela le ngqungquthela ngokugcina umlinganiselo ochanekileyo wamanzi kumxube, ngaloo ndlela ukhusela i-samente ekuqhekekeni.

I-MHEC iphinda isebenze njengefilimu ekhuselayo kwindawo ye-samente, ikhusela amanzi ukuba aphume emoyeni. Le filimu ikwanceda ukugcina ubumanzi bokuqala besamente, inciphisa ngakumbi amathuba okuqhekeka.

I-MHEC ikwalungele okusingqongileyo. Okokuqala, i-biodegradable, oko kuthetha ukuba ayihlali kwindawo engqongileyo ixesha elide. Okwesibini, kunokunceda ukunciphisa isixa sesamente esifunekayo kwiiprojekthi zokwakha. Oku kungenxa yokuba i-MHEC ikwandisa ukusebenza kunye ne-viscosity ye-cement, ukunciphisa imfuno yamanzi angaphezulu adibanisa nje umxube we-samente.

Ukusetyenziswa kwe-MHEC kwisamente kunika iingenelo ezininzi kwaye kungenza igalelo elibalulekileyo kwishishini lokwakha. Iphucula ukusebenza komxube we-samente, inciphisa inani leentanda ezenziwe ngexesha lokunyanga, ikhuthaza i-cement hydration kunye namandla, kwaye yenza njengefilimu ekhuselayo kwindawo ye-samente. Ukongeza, i-MHEC ilungile kokusingqongileyo. Ngoko ke, i-MHEC iyimveliso ebalulekileyo kwishishini lokwakha njengoko liphucula umgangatho we-samente kwaye libonelela ngeenzuzo kubasebenzi kunye nokusingqongileyo.
