(1) Uhlolojikelele lwe-hydroxypropyl methylcellulose esheshayo
I-Instant hydroxypropyl methylcellulose (HPMC) iyi-ether engeyona i-ionic cellulose etholwe ngokuguqulwa kwamakhemikhali e-cellulose yemvelo futhi inezici ezinhle zokuncibilika nezici ze-viscosity.Isakhiwo sayo samangqamuzana siqukethe amaqembu e-hydroxyl, methoxy kanye ne-hydroxypropoxy.Lawa maqembu asebenzayo ayinikeza izakhiwo eziyingqayizivele zomzimba namakhemikhali, okwenza ibaluleke ezinhlobonhlobo zezicelo.
(2) Umsebenzi we-HPMC kuma-adhesives wokwakha
Emkhakheni wokwakha, i-HPMC iyisengezo esibalulekile futhi isetshenziswa kabanzi ezintweni ezinamathelayo zokwakha ezihlukahlukene, njengezinamathiselo zamathayili, ama-wall putties, udaka olomile, njll. Imisebenzi yayo eyinhloko ekunamathiseleni ukwakhiwa ihlanganisa:
1. Ukuqina komphumela
I-HPMC ingakhuphula ngokuphawulekayo i-viscosity kanye nokuvumelana kwezinamathiselo zokwakha.Umphumela wayo wokuqina uvela endaweni yayo yokuvuvukala emanzini kanye nesakhiwo senethiwekhi ye-intermolecular hydrogen bond.I-viscosity efanelekile ingathuthukisa ukusebenza kwezinto ngesikhathi sokwakhiwa futhi ivimbele okunamathelayo ekuncipheni uma kusetshenziswe ezindaweni eziqondile, ngaleyo ndlela kuqinisekiswe ikhwalithi yokwakha.
2. Ukugcinwa kwamanzi umphumela
I-HPMC inezindawo ezinhle kakhulu zokugcina amanzi, ezinganciphisa ukulahleka kwamanzi ngesikhathi sokwakha.Ukugcinwa kwamanzi kuyisici esibalulekile sezinto zokunamathisela zokwakha.Ikakhulukazi ezintweni ezisekelwe kusimende kanye ne-gypsum-based, umphumela wokugcina amanzi we-HPMC unganweba isikhathi esivulekile sokunamathela, unikeze ukulungiswa okude nesikhathi sokwakha, ukuvimbela ukuqhekeka kusenesikhathi nokunciphisa amandla.
3. Thuthukisa ukusebenza
I-HPMC ingathuthukisa kakhulu ukusebenza kwezinamatheliso zokwakha, okuhlanganisa uketshezi, ukwakhiwa kanye nokucaba.Umphumela wayo wokugcoba wenza i-adhesive ibe lula ukuyisebenzisa futhi iklwelwe ngesikhathi sokwakhiwa, ithuthukisa ukusebenza kahle kokwakhiwa kanye nokucaba kwendawo yokwakha, futhi iqinisekisa umphumela wokugcina wokwakha.
4. Thuthukisa amandla okuxhumana
I-HPMC ingathuthukisa ukunamathela phakathi kwe-adhesive kanye ne-substrate futhi ithuthukise amandla okubopha we-adhesive ngokwenza ungqimba olufana nolwe-bonding.Lokhu kubalulekile ekuzinzeni kwezakhiwo zokwakha njengezindonga naphansi, futhi kungavimbela ngempumelelo amathayela, ama-tile abheke, njll. ukuthi angawi.
5. Ukusebenza kwe-anti-slip
Kuzinhlelo zokusebenza ezifana nokunamathiswa kwamathayela, i-HPMC ingathuthukisa ikhono lokungasheleli lento.Lokhu kusiza ukugcina amathayela egxilile ezindaweni zokwakha eziqondile, ukunciphisa imvamisa yokulungiswa nomthwalo womsebenzi, futhi ngaleyo ndlela kuthuthukiswe ikhwalithi yokwakha.
(3) Ukusetshenziswa okuqondile kwe-HPMC ezintweni ezinamathelayo ezakhiweni ezahlukene
1. I-adhesive ye-tile
Ekunamatheleni kwamathayela, i-HPMC ayidlali nje indima ekujikeni nasekugcineni amanzi, kodwa futhi ithuthukisa ukusebenza okunqanda ukushelela kokunamathela kwamathayili, iqinisekisa ukuzinza kwamathayili ngesikhathi sokwakhiwa.Izakhiwo zayo eziyingqayizivele ze-rheological zenza i-adhesive igcine i-viscosity efanelekile ngaphansi kwezimo ezahlukene zokwakha, okwenza kube lula ukulungisa nokwakha.
2. I-wall putty
I-HPMC idlala indima enkulu ekugcineni amanzi kanye nokujiya ku-putty odongeni, okwenza i-putty isebenze kakhulu futhi ibe nendawo ebushelelezi ngemva kokoma.Ukugcinwa kwayo kwamanzi kunganciphisa ukuqhekeka nokuncipha kwesendlalelo se-putty ngesikhathi sokwakhiwa, futhi kuthuthukise ikhwalithi yokugqoka kokugcina.
3. Udaka olomile
Odakeni olomile, umsebenzi oyinhloko we-HPMC ukugcina umswakama nokuvimbela ukulahleka kwamanzi kusenesikhathi, ngaleyo ndlela kuthuthukisa ukusebenza nokunamathela kodaka.Ingaphinda ilungise ukuhambisana kodaka ukuze iyenze ifaneleke ezimeni ezahlukene zokwakha, njengodaka lwamatshe, udaka lokuplasta, njll.
4. I-sealant yokwakha
I-HPMC isetshenziswa kakhulu ekwakheni ama-sealant ukuze kuthuthukiswe uketshezi nokusebenza kwe-colloid, ukuze ikwazi ukugcwalisa amalunga ngesikhathi sokufaka isicelo futhi igcine ukunwebeka okuhle nokunamathela.Ukugcinwa kwayo kwamanzi kungavimbela futhi i-sealant ekulahlekelweni kwamanzi ngokushesha futhi kuthuthukise ikhwalithi yokwakha.
(4) Izinzuzo ze-HPMC ekwakheni okunamathelayo
Ukuvikelwa kwemvelo: I-HPMC isuselwa ku-cellulose yemvelo, inezici zamakhemikhali ezizinzile, ayikhiphi izinto eziyingozi ngesikhathi sokusetshenziswa, futhi inobungani nemvelo nomzimba womuntu.
Ukuzinza: I-HPMC inokuqina okuhle kwamakhemikhali futhi ayithinteki kalula yizici zemvelo ezifana nezinga lokushisa ne-pH, futhi ingagcina ukusebenza kwayo isikhathi eside.
Ukuhambisana: I-HPMC ihambisana nezinhlobonhlobo zezinto zokwakha futhi ingahlanganiswa kahle nezinto ezifana nosimende, igypsum, nodaka ukuze yenze imisebenzi yayo yokujiya nokugcina amanzi.
(5) Amathrendi entuthuko yesikhathi esizayo
Ngokuthuthuka kobuchwepheshe bokwakha, amathemba okufaka isicelo e-HPMC ekwakheni okunamathelayo abanzi.Izikhombisi-ndlela zentuthuko ezizayo zifaka:
Ukuthuthukiswa kokusebenza: Thuthukisa ukusebenzisana kwezinto ezihlukahlukene kwe-HPMC ngokuguqulwa kwamakhemikhali noma ngokuhlanganisa nezinye izithasiselo ukuze kuhlangatshezwane nezidingo zezinhlelo zokusebenza ezahlukene zokwakha.
Imikhiqizo ehambisana nemvelo: Thuthukisa imikhiqizo ye-HPMC evumelana nemvelo futhi eyonakalayo ukuze unciphise umthelela emvelweni.
Izinto ezihlakaniphile: Hlola ukusetshenziswa kwe-HPMC ezintweni zokwakha ezihlakaniphile, njengezinto zokunamathela eziziphilisayo, izinto ezisabela kukushisa, njll., ukuze kuthuthukiswe izinga lobuhlakani bezinto zokwakha.
I-Instant hydroxypropyl methylcellulose, njengesengezo esibalulekile sokwakha izinto zokunamathisela, idlala indima ebalulekile ekuthuthukiseni i-viscosity, ukugcinwa kwamanzi, kanye nezakhiwo zokwakha izinto zokunamathisela.Ukusetshenziswa kwayo kuma-adhesives amathayili, i-wall putty, udaka olomile nezinye izinkambu kuye kwathuthukisa kakhulu izinga lokwakha nokusebenza kahle.Ngokuzayo, ngokusungula izinto ezintsha zobuchwepheshe kanye nokwenza ngcono ukuqwashisa ngemvelo, ukusetshenziswa kwe-HPMC ekwakheni izinto ezinamathelayo kuzongenisa indawo ebanzi yokuthuthukiswa.
