Izithasiselo zibe yingxenye evamile yokunamathisela amathayili futhi zidlala indima ebalulekile ekusebenzeni nasekuphumeleleni kwazo.Ukusetshenziswa kwezithasiselo ku-adhesive tile kubalulekile embonini yezokwakha yanamuhla.Izithasiselo zisiza ukuthuthukisa izici zokunamathela ezifana nokugcinwa kwamanzi, ukucutshungulwa namandla ebhondi, zizenze zisimame futhi zisebenze.I-HPMC (Hydroxypropyl Methyl Cellulose) iyisibonelo sesithasiselo esivame ukusetshenziswa embonini yokunamathisela amathayili.Lesi sihloko sichaza izinzuzo zokusebenzisa i-HPMC ekwenzeni i-adhesive adhesive.
Ayini ama-HPMC?
IHydroxypropyl methylcellulose iphuma ku-cellulose futhi yenza impushana emhlophe noma ekhanyayo ephuzi.Ayinabuthi, ayinaphunga futhi inokuncibilika okuhle kakhulu kwamanzi.I-HPMC itholwa nge-hydrolysis yemicu yezitshalo ukuze kukhiqizwe i-cellulose, ebuye ishintshwe amakhemikhali ngokungeza amaqembu e-methoxy kanye ne-hydroxypropyl ekuxhumaneni kwe-ether.Incibilika emanzini, i-ethanol ne-acetone futhi inezakhiwo ezithile zamakhompiyutha ezinto eziphilayo nezingaphili.Isetshenziswa kakhulu ezimbonini ezifana nezokwakha, izimonyo, ukudla, ezemithi kanye nezingubo zokugqoka.
Izinzuzo Zokusebenzisa i-HPMC Kuzinto Ezinamathelayo Zamathayela
1. Thuthukisa ukugcinwa kwamanzi
Enye yezinzuzo eziyinhloko zokusebenzisa i-HPMC ku-adhesives yamathayili ukuthi ithuthukisa ukugcinwa kwamanzi.Ukugcinwa kwamanzi kubalulekile enqubweni yokukhiqiza okunamathelayo njengoba kuqinisekisa ukuthi ingcina ihlala isebenza futhi ayisheshi yome.Lapho i-HPMC yengezwa ku-adhesive, ihlangana nama-molecule amanzi ukuze kwakheke ukufana okufana nejeli.Imvelo yejeli ye-HPMC iqinisekisa ukuthi ingxube yokunamathela ihlala imanzi futhi ihlangene, okuthuthukisa ukucutshungulwa kokunamathela futhi kuthuthukise ukubopha kwamathayili.
2. Thuthukisa ukusebenza
Ukusetshenziswa kwe-HPMC kuma-adhesives we-tile kuthuthukisa ukusebenza, okuwukuthi i-adhesive ixutshwa kalula, isetshenziswe futhi ilungiswe kalula kanjani.I-machinability ibalulekile enqubweni yokukhiqiza njengoba inquma ukusebenza kahle kwenqubo yokufaka.Uma i-HPMC yengezwa kuma-adhesives, isebenza njenge-thickener, okuholela ekushintshaneni okungcono nokuphatha okulula.Ukuvumelana okuthuthukisiwe kwe-adhesive kuqinisekisa ukuthi ihlala ihlangene futhi ingabunjwa kalula, ibunjwe noma isakazwe ezindaweni ezisezingeni eliphezulu ukuze idale indawo ebushelelezi.
3. Khulisa amandla esibopho
Amandla ebhondi anqunywa isibopho phakathi kwe-substrate (i-tile) ne-adhesive.Ukusebenzisa i-HPMC kokunamathela kuthayela kukhulisa amandla ebhondi ngokwandisa isibopho phakathi kwethayela nokunamathelayo.Indima ye-HPMC ukukhulisa indawo yokuxhumana phakathi kwe-substrate ne-adhesive.Lokhu kuthintana okuthuthukisiwe kubangela isibopho esiqinile esingamelana nokucindezela okukhulu nesisindo.Ukunamathela okuqinile okuhlinzekwa yi-HPMC kuqinisekisa ukuthi amathayili ahlala endaweni ngisho nasezindaweni zethrafikhi ephezulu futhi ahlala emelene namandla emishini.
4. Yehlisa ukushwabana
Njengoba ingcina isoma, iyashwabana, idale izikhala nezikhala phakathi kwama-tile.Izikhala nezikhala zingabonakala zingabukeki futhi zivumele umswakama ukuthi ungene, okungabangela ukuba ama-tile axebuke.Ukusebenzisa i-HPMC kumathayela anamathelayo kuqinisekisa ukuthi ingcina yoma kancane futhi ngokulinganayo, kunciphisa ukushwabana.Inqubo yokomisa kancane ivumela i-adhesive ukuthi ixazulule, iqinisekise ukuthi i-tile ngayinye ibeka ngokulinganayo, inciphisa ingozi yezikhala ngenxa yokuncipha.
5. Thuthukisa ukumelana nesimo sezulu
Ukusetshenziswa kwe-HPMC ku-adhesives yamathayili kungathuthukisa isimo sezulu se-adhesive.I-HPMC inikeza ungqimba olwengeziwe lwesivikelo, iqinisekisa ukuthi ingcina ihlala injalo ngisho nasezimweni zezulu ezinzima.Izimo zangaphandle ezifana nokushintshashintsha kwezinga lokushisa, umswakama kanye nemvula zingenza buthaka isibopho se-adhesive futhi kunciphise ukusebenza kwayo.I-HPMC inikeza ukunamathela okuvikelayo okuvikela okunamathelayo ezimweni zezulu ezinzima, iqinisekisa ukuthi ihlala isebenza isikhathi eside.
Ekuphetheni
Ukwengeza i-HPMC kokunamathiselwe kuthayela kunikeza izinzuzo ezibalulekile, kuthuthukisa ukusebenza kwe-adhesive, ukusebenza, ukusimama namandla.Izinzuzo zihlanganisa ukugcinwa kwamanzi okuthuthukisiwe, ukucutshungulwa okuthuthukisiwe, amandla ebhondi akhuphukayo, ukuncipha kokuncipha kanye nesimo sezulu esithuthukisiwe.Lezi zinzuzo zingathuthukisa ikhwalithi yemisebenzi yokwakha ehlala injalo futhi isebenza ngisho nasezimweni zezulu ezimbi.Ngenxa yezinzuzo zayo eziningi, ukusetshenziswa kwe-HPMC ku-adhesives yamathayili sekuyinto evamile embonini yokukhiqiza i-adhesive adhesive.Ukuguquguquka kwayo kuyenze yathandwa futhi yaba ukukhetha kokuqala kochwepheshe bezokwakha emhlabeni wonke
