I-HPMC (HYDROXYPROPYL Methylcellulose)yi-poly-soluble polymer compact eguqulwa ngamakhemikhali kusuka ku-cellulose yemvelo. Kusetshenziswa kabanzi emikhakheni eminingi efana nokwakha, ukumboza, umuthi nokudla. Embonini yezokwakha, i-HPMC, njengesengezo esibalulekile sodumo, ingathuthukisa kakhulu ukusebenza kodaka futhi ithuthukise ukusebenza kwayo, ukugcinwa kwamanzi, ukunxusa, njll.
1. Ukusebenza okuyisisekelo nemisebenzi ye-HPMC
I-HPMC inezakhiwo ezilandelayo ezilandelayo:
Ukuqina:ICICCINCELX ®PPMCIngakhulisa kakhulu ukubonwa kodaka, okwenza umfaniswano kasimende futhi uzinze, futhi kube lula ukuzisebenzisa ngesikhathi sokwakha.
Ukugcinwa kwamanzi: I-HPMC inganciphisa ukuhwamuka kwamanzi kudaka, ukubambezela ijubane elikhuni ngodaka, futhi liqinisekise ukuthi udaka ngeke lolome ngaphambi kwesikhathi ngesikhathi sokwakha, ngaleyo ndlela ugweme ukwenzeka kwemifantu.
I-RHEOLOGY: Ngokushintsha uhlobo kanye nomthamo we-HPMC, uketshezi lodaka lungathuthukiswa, okwenza kube bushelelezi futhi kube lula ukwakha ngesikhathi.
I-Adhesion: I-HPMC ine-degree ethile yokunamathela futhi ingathuthukisa amandla okubopha phakathi kodaka kanye nezinto ezisetshenziswayo, ezibaluleke kakhulu ngodaka oludonsayo nodaka oluhlobisa lodonga lwangaphandle.
2. Ukusetshenziswa kwe-HPMC ngohlobo oluhlukile
2.1 Isicelo ku-dilasting ngodaka
Udaka oluphamba luhlobo lodaka oluvame ukusetshenziswa ekwakheni. Imvamisa isetshenziselwa ukupenda nokuhlobisa izindonga, ophahleni, njll. Imisebenzi esemqoka ye-HPMC ku-Plasting Data yilezi:
Thuthukisa ukukhiqizwa: I-HPMC ingathuthukisa uketshezi lodaka oluphambayo, okwenza kube yunifomu ngokwengeziwe futhi bushelelezi ngesikhathi sokwakha, okwenza kube lula ukusebenza ukuze basebenze futhi banciphise ukuqina kwabasebenzi kubasebenzi.
Ukugcinwa kwamanzi okuthuthukisiwe: Ngenxa yokugcinwa kwamanzi kwe-HPMC, udaka olubusayo angagcina umswakama owanele ukuvimba udaka ekumiseni ngokushesha okukhulu, ebangela izinkinga ezinjengenqubo yokwakha.
Thuthukisa i-Adhesion: I-HPMC ingathuthukisa ukunamathela phakathi kodaka nodonga substrate, ukuvimbela udaka ekuweni noma ukuqhekeka. Ikakhulu kumaphrojekthi wokufaka odongeni wangaphandle, kungavimba ngempumelelo ukulimala kokwakheka okubangelwa yizinto zangaphandle ezifana nezinguquko zokushisa.
2.2 Isicelo kudumbu lodonga olungaphandle
Isidumbu sodonga lwangaphandle sangaphandle luhlobo lodaka oluhlanganisiwe, oluvame ukusetshenziselwa ukwakhiwa ungqimba olufakwayo lwezakhiwo zangaphandle. Ukusetshenziswa kwe-HPMC kudumo ngodonga olungaphandle lokufakwa kodonga kuboniswa ikakhulukazi ezicini ezilandelayo:
Isikhangiso esithuthukisiwe: Isidumbu sodonga lwangaphandle olungaphandle ludinga ukuhlanganiswa namabhodi wokufaka okufakwayo (njengama-EPS, amabhodi we-XPS, amabhodi woboya edwala, njll.). I-HPMC ingathuthukisa ukunamathela phakathi kodaka kanye nalezi zinto zokuqinisekisa ukuqina nokuqina kongqimba lokufakelwa. ucansi.
Thuthukisa ukukhiqizwa: Kusukela ngodumo lokufakwa okushisayo okuvame ukuba khona ngendlela ye-powder eyomile, i-hpmc ingathuthukisa uketshezi lwayo ngesengezo ngemuva kokungeza amanzi, iqinisekise ukuthi udaka lungasetshenziswa ngokulinganayo ngesikhathi sokwakha futhi aluthambekele.
Thuthukisa ukumelana kokuqhekeka: Kumaphrojekthi wokufaka odongeni wangaphandle, izinguquko ezinkulu zokushisa zingadala imifantu. I-HPMC ingathuthukisa ukuguquguquka kodaka, ngaleyo ndlela yanciphisa ngokuphumelelayo ukuvela kwemifantu.
2.3 Isicelo ngodaka lwamanzi
UDotar ongangeni manzi usetshenziselwa amaphrojekthi angenamanzi kanye namaphrojekthi wokufaka umswakama, ikakhulukazi ezindaweni ezithambekele ekungeneni kwamanzi njengezisekelo nezindlu zokugezela. Ukusebenza kwesicelo se-HPMC ngoGotar wamanzi kungokulandelayo:
Ukugcinwa kwamanzi okuthuthukile
Thuthukisa ukunamathela: ekwakheni udaka lwamanzi, ukunamathela phakathi kodaka kanye nokuqukethwe kwesisekelo kubaluleke kakhulu. I-HPMC ingathuthukisa ukunamathela phakathi kwezinto zodaka nezisekelo ezifana nokhonkolo kanye nama-masonry ukuvimbela ungqimba lwamanzi kusuka ekunciphiseni bese uwa. .
Ukwenza ngcono i-fluidity: kudingeka udaka olungananzi amanzi ukuze ube nobunzima obuhle. I-HPMC inyusa u-fluidity futhi ithuthukise ukusebenziseka ukuze udaka lwamanzi lungaze lumboze ngokulinganayo impahla eyisisekelo ukuze aqinisekise umphumela ongavunyelwe.
2.4 Isicelo ku-dat-selveling data
Udaka lokuzilinganisa lusetshenziselwa ukuvelela phansi futhi luvame ukusetshenziswa ekwakheni phansi, ukufakwa kwezinto ezibonakalayo, njll. Izicelo zeICICCINCELX ®PPMCKu-Maler-Welsering Bonders kufaka:
Thuthukisa ushukela kanye nokuzilinganisa: I-HPMC ingathuthukisa kakhulu uketshezi lodaka lokuzimela, olunikeze ukugcwala okungcono, ukuvumela ukugeleza ngokwemvelo, ukugwema ama-bubble noma izindawo ezingalingani.
Ukugcinwa kwamanzi okuthuthukisiwe: Udaka oluzimisele ludinga isikhathi eside ukusebenza ngesikhathi sokwakha. Ukusebenza kokugcinwa kwamanzi kwe-HPMC kungabambezela ngempumelelo isikhathi sokuqala sodaka futhi ugweme ubunzima bokwakha obukhulayo ngenxa yokomiswa ngaphambi kwesikhathi.
Thuthukisa ukumelana nokuqhekeka: Udaka oluzimele lungaba ngaphansi kwengcindezi ngesikhathi senqubo yokwelapha. I-HPMC ingakhuphula ukuguquguquka nokumelana nokuqhekeka kodaka futhi kunciphise ubungozi bokuqhekeka emhlabathini.
I-3. Iqhaza eliphelele le-HPMC kuDinga
Njengesengezo esibalulekile kuDinga, i-HPMC ingathuthukisa ukusebenza kwayo okuphelele ngokulungisa izakhiwo zomzimba nezamakhemikhali zodaka. Phakathi kwezinhlobo ezahlukene zodaka, ukusetshenziswa kwe-HPMC kungashintshwa ngokuya ngezidingo zangempela ukuze kufinyelelwe umphumela omuhle wokwakha nokusebenza kwesikhathi eside:
Ku-fortar olandu, kuthuthukisa kakhulu ukuwenza, ukugcinwa kwamanzi nokutholwa kodaka;
Esithweni sodonga lwangaphandle odongeni, amandla eBonding ane-infation aqiniswa ukuze athuthukise ukumelana nokuqina komzimba;
Ngodaka lwamanzi, kuthuthukisa ukugcinwa kwamanzi nokunamathela kwamanzi, futhi kuthuthukise ukusebenza kokwakha;
Ngodaka lokuzimela, kuthuthukisa uxhaso, ukugcinwa kwamanzi kanye nokumelana nokuqhekeka ukuqinisekisa ukwakhiwa okubushelelezi.
Njengesengezo se-polymer esisebenzayo, i-ComCinCel®HPMC inamathemba wokusebenzisa abanzi ezingotsheni zokwakha. Ngokuthuthuka okuqhubekayo kobuchwepheshe bokwakha, izinhlobo nemisebenzi ye-HPMC kuzoqhubeka nokuthuthukiswa, futhi indima yayo ekwenzeni ngcono ukusebenza kodaka, ukwenza ngcono ukusebenza kahle kokwakha, kanye nokuqinisekisa ukuthi ikhwalithi yephrojekthi izothuthuka ngokwengeziwe. Ngokuzayo, ukusetshenziswa kwe-HPMC enkombeni yokwakha kuzokhombisa ukuthambekela okubanzi futhi okuhlukahlukene.
