I-Hydroxypropyl methylcellulose (HPMC)yikhemikhali ye-polymer yendalo esetyenziswa kakhulu kwizixhobo zokwakha, ingakumbi kwiimortar, ii-coating, i-adhesives kunye nezinye iimveliso. Umsebenzi ophambili womxube we-HPMC kukuphucula ukusebenza kolwakhiwo lwemortar, ukuphucula ukugcinwa kwamanzi kunye nokwandisa ixesha lokuvulwa. Njengoko imfuno yezixhobo zokusebenza okuphezulu kushishino lokwakha iqhubeka isanda, ukusetyenziswa kwe-HPMC kuye kwafumana ingqalelo enkulu.
1. Iimpawu ezisisiseko ze-HPMC
I-HPMC yi-cellulose ether enyibilikayo emanzini eneempawu zokufunxa amanzi, ukunamathela kunye nokuqina. Ingaphucula kakhulu ukugcinwa kwamanzi kwi-mortar, yandise ixesha lokuvula, kwaye iphucule ukumelana nokuwa kunye nokusebenza kolwakhiwo lwe-mortar. Ezi mpawu zibalaseleyo zenza i-HPMC ibe yenye yezinto eziqhelekileyo kwi-mortar nakwezinye izixhobo zokwakha.
2. Inkqubo yokomisa udaka
Inkqubo yokomisa i-mortar idla ngokuquka iinxalenye ezimbini: ukufuma kwamanzi kunye nokusabela kokufuma kwesamente. Ukufuma kwesamente yindlela ephambili yokunyanga i-mortar, kodwa ukufuma kwamanzi ngexesha lokomisa nako kudlala indima ebalulekileyo. Ukufuma kwi-mortar yesamente kufuneka kususwe kancinci ngenkqubo yokufuma, kwaye isantya sale nkqubo sichaphazela ngokuthe ngqo umgangatho, ukuqina kunye nokusebenza kokwakhiwa okulandelayo kwemveliso egqityiweyo emva kokwakhiwa.
3. Impembelelo ye-HPMC kwisantya sokomisa udaka
Impembelelo yomxube we-AnxinCel®HPMC kwisantya sokomisa i-mortar ibonakala kakhulu kwiinkalo ezimbini: ukugcinwa kwamanzi kunye nolawulo lokuphuma kwamanzi emkhenkceni.
(1) Ukugcinwa kwamanzi okuphuculweyo kunye nesantya sokomisa esicothayo
I-HPMC ineempawu ezinamandla zokufuma kunye nokugcina amanzi. Ingenza ifilimu yokufuma kwi-mortar ukunciphisa ukufuma kwamanzi ngokukhawuleza. Okukhona ukugcinwa kwamanzi kwi-mortar kungcono, kokukhona yoma kancinci kuba amanzi agcinwa kwi-mortar ixesha elide. Ke ngoko, emva kokongeza i-HPMC, inkqubo yokufuma kwamanzi kwi-mortar iya kuthintelwa kwinqanaba elithile, nto leyo ekhokelela kwixesha elide lokoma.
Nangona ukucothisa ukufuma kwamanzi kunokwenza ixesha lokomisa i-mortar lihlale lide, le nkqubo yokomisa kancinci iluncedo, ingakumbi ngexesha lenkqubo yokwakha, njengoko inokuthintela ngempumelelo iingxaki ezinje ngokoma komphezulu kunye nokuqhekeka kwe-mortar kwaye iqinisekise umgangatho wokwakha.
(2) Ukulungiswa kwenkqubo yokufunxwa kwesamente
Indima ye-HPMC kwi-samente mortar ayipheleli nje ekuphuculeni ukugcinwa kwamanzi. Ingalawula nenkqubo yokufunxa amanzi kwi-samente. Ngokutshintsha i-rheology ye-samente, i-HPMC inokuchaphazela inqanaba lokudibana phakathi kwamasuntswana esamente kunye nokufuma, ngaloo ndlela ichaphazela izinga lokufunxa amanzi kwi-samente. Kwezinye iimeko, ukongezwa kwe-AnxinCel®HPMC kunokulibazisa kancinci inkqubo yokufunxa amanzi kwi-samente, okubangela ukuba i-samente iphole kancinci. Esi siphumo sidla ngokufezekiswa ngokulungelelanisa ukusasazwa kobungakanani bamasuntswana esamente kunye nokuqhagamshelana kwamasuntswana esamente, ngaloo ndlela kuchaphazele isantya sokomisa.
(3) Ukuziqhelanisa nokufuma kokusingqongileyo
I-HPMC inokuphucula ukumelana nokuphuma kwamanzi kwi-mortar, yenze i-mortar ikwazi ukuzivumelanisa nokufuma kwendalo. Kwindawo eyomileyo, isiphumo sokugcina amanzi se-HPMC sibaluleke kakhulu. Ingayilibazisa ngempumelelo ilahleko yokufuma komphezulu kwaye inciphise ukuqhekeka komphezulu okubangelwa sisantya esomileyo. Oku kubaluleke kakhulu kwiindawo ezishushu okanye ezomileyo. Ke ngoko, i-HPMC ayilungisi nje kuphela izinga lokuphuma kwamanzi, kodwa ikwaphucula ukuzivumelanisa kwe-mortar nendalo yangaphandle, yandisa ngokungathanga ngqo ixesha lokomisa.
4. Izinto ezichaphazela isantya sokomisa
Ukongeza kokongezwa komxube we-HPMC, isantya sokomisa sedaka sikwachaphazeleka zezinye izinto ezininzi, kuquka:
Umlinganiselo wesamente: Umlinganiselo wesamente kumanzi kunye nomlinganiselo wesamente ecolekileyo kumxube oqinileyo uya kuchaphazela umxholo wokufuma kwesamente kwaye ngaloo ndlela isantya sokomisa.
Iimeko zokusingqongileyo: Iimeko zobushushu, ukufuma kunye nokujikeleza komoya zizinto ezibalulekileyo ezichaphazela isantya sokomisa kwesamente. Kwimeko yobushushu obuphezulu kunye nokufuma okuphantsi, amanzi aphuma ngokukhawuleza, kwaye ngokuchaseneyo.
Ubukhulu besamente: Ubukhulu besamente buyichaphazela ngqo inkqubo yayo yokomisa. Iiscreed ezityebileyo zihlala zithatha ixesha elide ukuba zome ngokupheleleyo.
5. Iingqwalasela zesicelo esisebenzayo
Kwizicelo ezisebenzayo, iinjineli zokwakha kunye nabasebenzi bokwakha badla ngokufuna ukulinganisela isantya sokomisa se-mortar kunye nokusebenza kakuhle kwesakhiwo. Njengomxube, i-HPMC inokulibazisa isantya sokomisa, kodwa olu phawu luluncedo kakhulu kwiindawo apho ixesha lokwakha kufuneka ligcinwe khona. Umzekelo, kwiindawo ezinobushushu obuphezulu, ezomisa umoya, i-HPMC inokuthintela ngokufanelekileyo ukoma komphezulu kunye nokuqhekeka, iqinisekisa ukusebenza ngcono kunye nexesha elide lokuvula i-mortar ngexesha lokwakha.
Nangona kunjalo, kwezinye iimeko ezithile, ezifana neeprojekthi ezifuna ukomiswa ngokukhawuleza kwesamente, kunokufuneka ukulawula ubungakananiI-HPMCyongeza okanye khetha ifomula engenayo i-HPMC ukukhawulezisa inkqubo yokomisa.
Njengomxube we-mortar, i-AnxinCel® HPMC inokuphucula ngokufanelekileyo ukugcinwa kwamanzi kwi-mortar, yandise ixesha lokuvula, kwaye ichaphazele ngokungathanga ngqo isantya sokomisa se-mortar. Emva kokongeza i-HPMC, isantya sokomisa se-mortar sidla ngokucotha, nto leyo enefuthe elihle ekuphepheni iingxaki ezifana nokuqhekeka okomileyo ngexesha lokwakha. Nangona kunjalo, utshintsho kwisantya sokomisa luchaphazeleka zizinto ezahlukeneyo ezifana nomlinganiselo we-mortar kunye neemeko zokusingqongileyo. Ke ngoko, kwizicelo ezisebenzayo, ubungakanani be-HPMC kufuneka bukhethwe ngokufanelekileyo ngokweemeko ezithile ukuze kufezekiswe isiphumo esihle sokwakha.
