IHydroxypropyl Methylcellulose (HPMC) iyi-ether ye-cellulose ebalulekile enezinhlobonhlobo zezicelo embonini yezokwakha. Kuyinhlanganisela ye-polymer encibilika emanzini etholwe ngokushintsha amakhemikhali i-cellulose yemvelo. Inokuncibilika okuhle kwamanzi, ukuqina, ukwakheka kwefilimu, ukubopha, ukuthambisa kanye nezinye izici, ngakho idlala izindima ezihlukahlukene ezibalulekile ezintweni zokwakha.
1. Udaka lukasimende nokhonkolo
Odakeni lukasimende nokhonkolo, i-HPMC isetshenziswa kakhulu njengesigxivizo, isigcini samanzi kanye nesibophezelo. Imisebenzi yayo eyinhloko ihlanganisa:
Ukuqina komphumela: I-HPMC ingakhuphula i-viscosity kasimende noma ukhonkolo, ngaleyo ndlela ithuthukise ukusebenza kokwakhiwa futhi yenze kube lula ukusabalala nokusebenza. Ngaphezu kwalokho, udaka olujiyile lungakwazi ukunamathela kangcono ku-substrate futhi lunciphise amathuba okuba impushana nokuwa.
Umphumela wokugcinwa kwamanzi: I-HPMC inamandla okugcina amanzi aqinile, anganciphisa ukulahlekelwa kwamanzi odaka noma ukhonkolo, andise isikhathi sokusabela kwe-hydration sikasimende, futhi ngaleyo ndlela ithuthukise amandla okugcina nokuqina. Lesi sici sibaluleke kakhulu ezindaweni zokushisa ezomile noma eziphezulu, njengoba zingavimbela ukuqhekeka kanye nokuqina okungaphelele okubangelwa ukomiswa ngaphambi kwesikhathi kukasimende.
Umthelela we-Anti-sagging: Uma wakha endaweni eqondile, i-HPMC ingavimbela udaka noma ukunamathela ekusheleleni phansi, igcine ukujiya komfaniswano nokumboza kahle.
2. Izinamatheliso zamathayili
Ezinamathiselwe zamathayili, indima ye-HPMC ibaluleke kakhulu. Akugcini nje ukuthuthukisa ukunamathela kwe-adhesive, kodwa futhi kuthuthukisa ukusebenza ngesikhathi sokwakhiwa. Ngokuqondile, iboniswa ngale ndlela elandelayo:
Ukuthuthukisa ukunamathela: I-HPMC ithuthukisa ukunamathela phakathi kwezinamathelisi zamathayili namathayili nama-substrates, iqinisekisa ukuzinza nokuqina kwamathayili ngemva kokubeka.
Ukuthuthukisa ukusebenza kokwakhiwa: I-HPMC ingandisa isikhathi sokuvula sokunamathisela amathayili, okungukuthi, yandise isikhathi lapho isikhundla se-tile singalungiswa ngaso ngaphambi kokuba i-adhesive isomile, ebaluleke kakhulu kubasebenzi bezokwakha futhi ingaqinisekisa ukunemba kokubeka i-tile.
I-Anti-slip: Kumathayela anosayizi omkhulu noma uma akha endaweni eqondile, i-HPMC ingavimbela ngempumelelo ukushelela kwamathayili, ngaleyo ndlela ithuthukise ikhwalithi yokwakha.
3. Uhlelo lwangaphandle lokufakwa kwezindonga
Kuhlelo lwangaphandle lokufakwa kwezindonga, i-HPMC iphinde idlale indima yokugcina amanzi, ukujiya kanye nokubopha. Uhlelo lwangaphandle lwe-insulation ludinga ukuthi izinto zokwakha zibe nezindawo ezinhle zokugcina amanzi ukuze kuqinisekiswe ukuthi i-bonding mortar ngeke ihluleke ngenxa yokulahlekelwa kwamanzi amaningi ngesikhathi sokwakha kanye nezigaba zokuphulukisa. Ukwengezwa kwe-HPMC kuthuthukisa ukusebenza, ukunamathela kanye nokumelana nokuqhekeka kodaka, ngaleyo ndlela kuthuthukisa ikhwalithi yokwakha kanye nokuqina kwalo lonke uhlelo lokufakelwa.
4. Izinto zokuzilinganisa phansi
Ezintweni ezizilinganisa phansi, i-HPMC idlala indima yokulawula uketshezi kanye nokwenza ngcono ukugcinwa kwamanzi. Lesi sici sidinga ukulinganisa ngesikhathi sokwakhiwa, kodwa asikwazi ukukhiqiza ukucwiliswa kwe-sedimentation ngokweqile noma i-stratification. Umthelela wokujiya we-HPMC ungagcina ukufana kwento ngaphandle kokuthikameza uketshezi, iqinisekise ukuthi indawo yaphansi iyisicaba futhi ibushelelezi.
5. I-putty powder
I-HPMC isetshenziswa kabanzi ku-putty powder ezindongeni zangaphakathi nangaphandle zezakhiwo. Ingakwazi ukuthuthukisa ukwakhiwa nokuqina kwe-putty powder, ithuthukise ukunamathela kwayo odongeni, futhi ithuthukise isikhathi sokumisa kanye nokumelana nokuqhekeka kwe-putty powder. Ikakhulukazi ezindaweni ezomile, i-HPMC ingavimbela ngokuphumelelayo ukuqhekeka kwendawo noma ukuwa okubangelwa ukulahlekelwa kwamanzi okusheshayo kwe-putty powder.
6. Ezinye izinhlelo zokusebenza
Ngaphezu kwalokhu kusetshenziswa okuyinhloko okungenhla, i-HPMC iphinde ibe nendima kwezinye izindawo zokwakha, njengemikhiqizo esekwe kwi-gypsum, okokugquma okungangenwa amanzi, izinto zokugaya, ama-sealant, njll. Izakhiwo zayo ezisebenza ngezinto eziningi ezifana nokujiya, ukugcinwa kwamanzi, kanye nokuhlanganisa isengezo esibalulekile ezintweni zokwakha.
IHydroxypropyl methylcellulose inezinhlobonhlobo zezicelo ezibalulekile embonini yezokwakha. Ithuthukisa kakhulu ikhwalithi nokusebenza kahle kokwakhiwa kwezinto zokwakha ngokuthuthukisa ukusebenza kokwakhiwa kwezinto ezisekelwe kusimende kanye ne-gypsum, ukwandisa isikhathi sokusebenza, ukuqinisa ukubopha, nokuthuthukisa ukumelana nokuqhekeka. Ngakho-ke, amathemba okufaka isicelo e-HPMC ekwakhiweni kwesimanje abanzi kakhulu, futhi ngokuthuthuka okuqhubekayo kobuchwepheshe bokwakha, indima ye-HPMC izogqama kakhulu.
