I-HPMC (i-hydroxypropyl methylcellulose) sisixhobo esibalulekileyo sokwakha kwaye sisetyenziswa kakhulu kwi-mortar yokuzilinganisa. I-mortar yokuzilinganisa sisixhobo esinokunyibilika okuphezulu kunye nokukwazi ukuzilinganisa, esisetyenziswa rhoqo ekwakheni umgangatho ukwenza umphezulu ogudileyo nothe tyaba. Kule ndlela yokusebenza, indima ye-HPMC ibonakala kakhulu ekuphuculeni ukunyibilika, ukugcinwa kwamanzi, ukunamathela kunye nokusebenza kokwakhiwa kwe-mortar.
1. Iimpawu kunye nendlela yokusebenza kwe-HPMC
I-HPMC yi-non-ionic cellulose ether ene-hydroxyl kunye namaqela e-methoxy kwisakhiwo sayo se-molecular, esenziwe ngokutshintsha ezinye ii-athomu ze-hydrogen kwii-molecule ze-cellulose. Iimpawu zayo eziphambili ziquka ukunyibilika kwamanzi kakuhle, ukuqina, ukugcinwa kwamanzi, ukuthambisa kunye nokukwazi ukubopha okuthile, okwenza ukuba isetyenziswe kakhulu kwizixhobo zokwakha.
Kwi-mortar e-self-leveling, iziphumo eziphambili ze-HPMC ziquka:
Isiphumo sokutyeba: I-HPMC yonyusa i-viscosity ye-self-leveling mortar ngokusebenzisana nee-molecule zamanzi ukwenza isisombululo se-colloidal. Oku kunceda ukuthintela ukwahlulwa kwe-mortar ngexesha lokwakhiwa kwaye kuqinisekisa ukufana kwezinto.
Ukugcinwa kwamanzi: I-HPMC inamandla okugcina amanzi, nto leyo enokunciphisa ngempumelelo ukulahleka kwamanzi ngexesha lenkqubo yokuqina kwe-mortar kwaye yandise ixesha lokusebenza kwe-mortar. Oku kubaluleke kakhulu kwi-mortar ezilinganisa ngokwayo, kuba ukulahleka kwamanzi ngokukhawuleza kunokubangela ukuqhekeka komphezulu okanye ukuhlala ngokulinganayo kwe-mortar.
Ulawulo lokuhamba kwamanzi: I-HPMC ingakwazi ukugcina ukutyibilika kakuhle kunye nokukwazi ukuzilinganisa ngokulawula ngokufanelekileyo i-rheology ye-mortar. Olu lawulo lunokuthintela i-mortar ekubeni nokutyibilika okuphezulu okanye okuphantsi kakhulu ngexesha lokwakha, ukuqinisekisa inkqubela phambili ethe tye yenkqubo yokwakha.
Ukusebenza kakuhle kokubopha: I-HPMC inokunyusa amandla okubopha phakathi kodaka oluzilinganisayo kunye nomphezulu wesiseko, iphucule ukusebenza kwayo kokunamathela, kwaye iphephe ukugoba, ukuqhekeka kunye nezinye iingxaki emva kokwakhiwa.
2. Ukusetyenziswa okuthe ngqo kwe-HPMC kwi-mortar yokuzilungisa
2.1 Ukuphucula ukusebenza kakuhle kolwakhiwo
I-mortar yokuzilinganisa idla ngokufuna ixesha elide lokusebenza ngexesha lokwakha ukuqinisekisa ukuhamba kakuhle kunye nexesha lokuyilinganisa. Ukugcinwa kwamanzi kwe-HPMC kunokwandisa ixesha lokuqala lokuseta i-mortar, ngaloo ndlela kuphucule ulungelelwaniso lokwakha. Ingakumbi kulwakhiwo lomgangatho olukhulu, abasebenzi bokwakha banokuba nexesha elingakumbi lokulungelelanisa kunye nokuyilinganisa.
2.2 Ukuphucula ukusebenza kwe-mortar
Isiphumo sokutyeba se-HPMC asinakuthintela kuphela ukwahlulwahlulwa kwe-mortar, kodwa sikwaqinisekisa ukusasazwa okufanayo kwe-aggregate kunye neenxalenye zesamente kwi-mortar, ngaloo ndlela siphucula ukusebenza kwe-mortar iyonke. Ukongeza, i-HPMC inokunciphisa ukuveliswa kwamaqamza kumphezulu we-mortar ezilinganisayo kwaye iphucule ukugqitywa komphezulu we-mortar.
2.3 Phucula ukumelana nokuqhekeka
Ngexesha lenkqubo yokuqina kwe-mortar yokuzilinganisa, ukufuma kwamanzi ngokukhawuleza kunokubangela ukuba umthamo wawo unciphe, ngaloo ndlela kubangele ukuqhekeka. I-HPMC inokucothisa ngempumelelo isantya sokomisa kwe-mortar kwaye inciphise amathuba okuqhekeka kokuqhekeka ngokugcina umswakama. Kwangaxeshanye, ukuguquguquka kwayo kunye nokunamathela kwayo kunceda ukuphucula ukumelana nokuqhekeka kwe-mortar.
3. Impembelelo yedosi ye-HPMC ekusebenzeni kodaka
Kwi-mortar ezimeleyo, ubungakanani be-HPMC eyongeziweyo kufuneka bulawulwe ngokungqongqo. Ngokwesiqhelo, ubungakanani be-HPMC eyongeziweyo buphakathi kwe-0.1% kunye ne-0.5%. Isixa esifanelekileyo se-HPMC sinokuphucula kakhulu ukugeleza kwamanzi kunye nokugcinwa kwamanzi kwi-mortar, kodwa ukuba idosi iphezulu kakhulu, inokubangela ezi ngxaki zilandelayo:
Ukutyibilika okuphantsi kakhulu: I-HPMC eninzi kakhulu iya kunciphisa ukutyibilika kwesamente, ichaphazele ukusebenza kolwakhiwo, kwaye ibangele nokungakwazi ukuzilinganisa.
Ixesha elandisiweyo lokuseta: I-HPMC egqithisileyo iya kwandisa ixesha lokuseta i-mortar kwaye ichaphazele inkqubela phambili yokwakha elandelayo.
Ngoko ke, kwiindlela ezisebenzayo, kuyimfuneko ukulungisa ngokufanelekileyo umthamo we-HPMC ngokwefomyula ye-self-leveling mortar, ubushushu be-ambient kunye nezinye izinto ukuqinisekisa ukusebenza kakuhle kolwakhiwo.
4. Impembelelo yeentlobo ezahlukeneyo ze-HPMC ekusebenzeni kwe-mortar
I-HPMC ineenkcazo ezahlukeneyo. Iintlobo ezahlukeneyo ze-HPMC zinokuba nefuthe elahlukileyo ekusebenzeni kwe-mortar yokuzilinganisa ngenxa yobunzima bazo obahlukeneyo beemolekyuli kunye namanqanaba okutshintsha. Ngokubanzi, i-HPMC enezinga eliphezulu lokutshintsha kunye nobunzima obukhulu beemolekyuli inefuthe eliqinileyo lokuqina kunye nokugcinwa kwamanzi, kodwa izinga layo lokunyibilika licotha. I-HPMC enezinga eliphantsi lokutshintsha kunye nobunzima obuphantsi beemolekyuli iyanyibilika ngokukhawuleza kwaye ifanelekile kwiimeko ezifuna ukunyibilika ngokukhawuleza kunye nokuxinana kwexesha elifutshane. Ke ngoko, xa ukhetha i-HPMC, kuyimfuneko ukukhetha uhlobo olufanelekileyo ngokweemfuno ezithile zokwakha.
5. Impembelelo yezinto ezisingqongileyo ekusebenzeni kwe-HPMC
Ukugcinwa kwamanzi kunye nefuthe lokutyeba kwe-HPMC kuya kuchaphazeleka yindawo yokwakha. Umzekelo, kwindawo enobushushu obuphezulu okanye kwindawo enomswakama ophantsi, amanzi ayaphela ngokukhawuleza, kwaye ifuthe lokugcina amanzi le-HPMC libaluleka kakhulu; kwindawo enomswakama, ubungakanani be-HPMC kufuneka buncitshiswe ngokufanelekileyo ukuze kuthintelwe ukubekwa kwe-mortar kancinci kakhulu. Ke ngoko, kwinkqubo yokwakha yokwenyani, ubungakanani kunye nohlobo lwe-HPMC kufuneka luhlengahlengiswe ngokweemeko zendalo ukuqinisekisa uzinzo lwe-mortar ezizilinganiselayo.
Njengesongezo esibalulekileyo kwi-mortar yokuzilinganisa, i-HPMC iphucula kakhulu ukusebenza kolwakhiwo kunye nesiphumo sokugqibela se-mortar ngokuyiqinisa, ukugcinwa kwamanzi, ukulungiswa kolwelo kunye nokuphucula ukunamathela. Nangona kunjalo, kwizicelo zokwenyani, izinto ezifana nobungakanani, uhlobo kunye nendawo yokwakha ye-HPMC kufuneka ziqwalaselwe ngokupheleleyo ukuze kufunyanwe isiphumo esihle sokwakha. Ngokuqhubeka nokuqhubela phambili kwetekhnoloji, ukusetyenziswa kwe-HPMC kwi-mortar yokuzilinganisa kuya kuba kubanzi kwaye kukhule.
