I-HPMC (Hydroxypropyl Methylcellulose)iyinhlanganisela ye-polymer encibilika emanzini eguqulwe ngamakhemikhali isuka ku-cellulose yemvelo. Isetshenziswa kabanzi emikhakheni eminingi efana neyokwakha, ukumboza, imithi, nokudla. Embonini yezokwakha, i-HPMC, njengesengezo esibalulekile sodaka, ingathuthukisa kakhulu ukusebenza kodaka futhi ithuthukise ukusebenza kwayo, ukugcinwa kwamanzi, ukusebenza, ukunamathela, njll.
1. Ukusebenza okuyisisekelo kanye nemisebenzi ye-HPMC
I-HPMC inezakhiwo eziyinhloko ezilandelayo:
Ukuqina:I-AnxinCel®HPMCkungandisa kakhulu i-viscosity yodaka, okwenza udaka lube lufana futhi luzinzile, futhi kulula ukulisebenzisa ngesikhathi sokwakhiwa.
Ukugcinwa kwamanzi: I-HPMC inganciphisa ukuhwamuka kwamanzi odakeni, ibambezele isivinini sokuqina kodaka, futhi iqinisekise ukuthi udaka ngeke lome ngaphambi kwesikhathi phakathi nenqubo yokwakha, ngaleyo ndlela igweme ukwenzeka kwemifantu.
I-Rheology: Ngokulungisa uhlobo nesikali se-HPMC, ukugcwala kodaka kungathuthukiswa, kukwenze kube bushelelezi futhi kube lula ukukwakha ngesikhathi sokufakwa.
Ukunamathela: I-HPMC inezinga elithile lokunamathela futhi ingathuthukisa amandla okubopha phakathi kodaka nezinto eziyisisekelo, okubaluleke kakhulu ekusebenzeni okufana nodaka olomile nodaka lwangaphandle lokuhlobisa.
2. Ukusetshenziswa kwe-HPMC emigodini ehlukene
2.1 Ukufakwa odakeni olukhonkolo
I-Plastering mortar wuhlobo lodaka oluvame ukusetshenziswa ekwakheni. Ivamise ukusetshenziselwa ukudweba nokuhlobisa izindonga, usilingi, njll. Imisebenzi esemqoka ye-HPMC kudaka lokuplasta yilena:
Thuthukisa ukusebenza kahle: I-HPMC ingathuthukisa ukuguquguquka kodaka lokuplasta, iyenze ifane futhi ibe bushelelezi ngesikhathi somsebenzi wokwakha, ikwenze kube lula kubasebenzi bokwakha ukuthi basebenze futhi yehlise izinga lomsebenzi kubasebenzi.
Ukugcinwa kwamanzi okuthuthukisiwe: Ngenxa yokugcinwa kwamanzi kwe-HPMC, udaka olukhonkolo lungagcina umswakama owanele ukuvimbela udaka ukuthi lome ngokushesha, lubangele izinkinga ezifana nokuqhekeka nokuchitheka ngesikhathi sokwakha.
Thuthukisa ukunamathela: I-HPMC ingathuthukisa ukunamathela phakathi kodaka kanye ne-substrate yodonga, ivimbele udaka ukuthi ungawi noma uqhekeke. Ikakhulukazi kumaphrojekthi wangaphandle wokuplasta odongeni, ingavimbela ngempumelelo ukulimala kwesakhiwo okubangelwa izici zangaphandle ezifana nokushintsha kwezinga lokushisa.
2.2 Ukufakwa odongeni lwangaphandle lokufakwa odongeni
Udaka lwangaphandle lokufakwa odongeni luhlobo lodaka oluyinhlanganisela, oluvame ukusetshenziswa ekwakhiweni kongqimba lwezindonga zesakhiwo sangaphandle. Ukusetshenziswa kwe-HPMC odongeni lwangaphandle lokufakwa odongeni kubonakala ikakhulukazi kulezi zici ezilandelayo:
Ukunamathela okuthuthukisiwe: Udaka lwangaphandle lokufakwa odongeni ludinga ukuhlanganiswa eduze namabhodi okufakelwa (njenge-EPS, amabhodi e-XPS, amabhodi woboya bedwala, njll.). I-HPMC ingathuthukisa ukunamathela phakathi kodaka kanye nalezi zinto zokwenziwa ukuze kuqinisekiswe ukuqina nokuzinza kwesendlalelo sokufakelwa. ucansi.
Thuthukisa ukusebenza kahle: Njengoba i-thermal insulation mortar ngokuvamile ikhona ngesimo se-powder eyomile, i-HPMC ingathuthukisa uketshezi kwayo ngezinto eziyisisekelo ngemva kokwengeza amanzi, iqinisekise ukuthi udaka lungasetshenziswa ngokulinganayo ngesikhathi sokwakha futhi alujwayele ukuwa noma ukuqhekeka.
Thuthukisa ukumelana nokuqhekeka: Kumaphrojekthi okufakwa odongeni angaphandle, izinguquko ezinkulu zokushisa zingase zidale imifantu. I-HPMC ingathuthukisa ukuguquguquka kodaka, ngaleyo ndlela inciphise ngempumelelo ukuvela kwemifantu.
2.3 Ukufaka odakeni olungangeni manzi
Udaka olungangeni manzi lusetshenziselwa ikakhulukazi amaphrojekthi okuvikela amanzi kanye namaphrojekthi angangenwa umswakama, ikakhulukazi ezindaweni ezivame ukungena emanzini njengezindlu zangaphansi nezindlu zangasese. Ukusebenza kwesicelo se-HPMC odakeni olungangeni manzi kanje:
Ukugcinwa kwamanzi okuthuthukisiwe: I-HPMC ingathuthukisa ngempumelelo ukugcinwa kwamanzi kodaka, yenze isendlalelo esingangeni manzi sifane futhi sizinze, futhi ivimbele amanzi ukuthi ahwamuke ngokushesha, ngaleyo ndlela iqinisekise ukwakheka nomphumela wokwakhiwa kongqimba olungangeni manzi.
Thuthukisa ukunamathela: Ekwakhiweni kodaka olunganamanzi, ukunamathela phakathi kodaka kanye nesisekelo sezinto kubaluleke kakhulu. I-HPMC ingathuthukisa ukunamathela phakathi kodaka kanye nezinto eziyisisekelo ezifana nokhonkolo namatshe ukuze kuvinjelwe ungqimba olungangeni manzi ukuthi lungaxebuka futhi liwe. .
Thuthukisa i-fluidity: Udaka olungangeni manzi luyadingeka ukuze ube noketshezi oluhle. I-HPMC inyusa uketshezi futhi ithuthukisa ukusebenza ukuze udaka olungangeni manzi lukwazi ukumboza ngokulinganayo izinto eziyisisekelo ukuze kuqinisekiswe umphumela wokuvimbela amanzi.
2.4 Ukufaka odakeni oluzilinganisa ngokwalo
Udaka oluzilinganisa lusetshenziselwa ukulinganisa phansi futhi luvame ukusetshenziswa ekwakhiweni kwaphansi, ukufakwa kwempahla yaphansi, njll.I-AnxinCel®HPMCEzisikeni ezizilinganisayo zihlanganisa:
Thuthukisa i-fluidity nokuzilinganisa: I-HPMC ingathuthukisa ngokuphawulekayo ukugeleza kodaka oluzilinganisa, ilunikeze izici ezingcono zokuzilinganisa, ukuyivumela ukuthi igeleze ngokwemvelo futhi isabalale ngokulinganayo, igweme amabhamuza noma izindawo ezingalingani.
Ukugcinwa kwamanzi okuthuthukisiwe: Udaka oluzilinganisa ludinga isikhathi eside ukuze lusebenze phakathi nenqubo yokwakha. Ukusebenza kokugcinwa kwamanzi kwe-HPMC kungabambezela ngempumelelo isikhathi sokuqala sokusetha udaka futhi kugweme ukwanda kobunzima bokwakha ngenxa yokomiswa ngaphambi kwesikhathi.
Thuthukisa ukumelana nokuqhekeka: Udaka oluzilinganisa lungase lube ngaphansi kwengcindezi ngesikhathi senqubo yokwelapha. I-HPMC ingakhuphula ukuguquguquka nokumelana nokuqhekeka kodaka futhi inciphise ubungozi bokuqhekeka phansi.
3. Iqhaza eliphelele le-HPMC odakeni
Njengesengezo esibalulekile kudaka, i-HPMC ingathuthukisa ukusebenza kwayo okuphelele ngokulungisa izakhiwo ezingokomzimba nezamakhemikhali zodaka. Phakathi kwezinhlobo ezahlukene zodaka, ukusetshenziswa kwe-HPMC kungalungiswa ngokuya ngezidingo zangempela ukuze kuzuzwe umphumela wokwakha ongcono kakhulu nokusebenza kwesikhathi eside:
Ngodaka lokukhonkoloza, ikakhulukazi kuthuthukisa ukusebenza, ukugcinwa kwamanzi kanye nokunamathela kodaka;
Odongeni lwangaphandle lokufakwa odongeni, amandla okubopha ngezinto zokufakelwa ayaqiniswa ukuze kuthuthukiswe ukumelana nokuqhekeka nokusebenza;
Ngodaka olungenamanzi, luthuthukisa ukugcinwa kwamanzi nokunamathela, futhi luthuthukise ukusebenza kokwakhiwa;
Esimendeni esizilinganisa, sithuthukisa uketshezi, ukugcinwa kwamanzi kanye nokumelana nokuqhekeka ukuze kuqinisekiswe ukwakhiwa okubushelelezi.
Njengesengezo se-polymer esisebenza ngezinto eziningi, i-AnxinCel®HPMC inamathuba abanzi okusebenza odakeni lokwakha. Ngokuthuthuka okuqhubekayo kobuchwepheshe bokwakha, izinhlobo nemisebenzi ye-HPMC izoqhubeka nokuthuthukiswa, futhi indima yayo ekuthuthukiseni ukusebenza kodaka, ukuthuthukisa ukusebenza kahle kokwakhiwa, kanye nokuqinisekisa ikhwalithi yephrojekthi izobaluleka kakhulu. Ngokuzayo, ukusetshenziswa kwe-HPMC emkhakheni wokwakha kuzokhombisa inkambiso ebanzi futhi ehlukahlukene.
