Ukusetshenziswa kwe-hydroxypropyl methylcellulose odakeni

1. Ukugcinwa kwamanzi

IHydroxypropyl methylcellulose yokwakha ivimbela umswakama ukuthi ungangeni odongeni.Inani elifanele lamanzi lihlala odakeni, ukuze usimende ube nesikhathi eside sokukhipha amanzi.Ukugcinwa kwamanzi kuhambisana ne-viscosity yesisombululo se-cellulose ether esisetsheni.Ukuphakama kwe-viscosity, kungcono ukugcina amanzi.Lapho ama-molecule amanzi anda, ukugcinwa kwamanzi kuncipha.Ngoba ngenani elifanayo lesisombululo se-hydroxypropyl methylcellulose esiqondene nokwakhiwa, ukwanda kwenani lamanzi kusho ukwehla kwe-viscosity.Ukwenziwa ngcono kokugcinwa kwamanzi kuzoholela ekwandiseni isikhathi sokulungisa udaka olwakhiwayo.

2. Thuthukisa ukwakhiwa

Ukusetshenziswa kwe-hydroxypropyl methylcellulose HPMC kungathuthukisa ukwakhiwa kodaka, kwenze umkhiqizo wodaka ube nokusebenza kangcono kokusabalalisa, ukunciphisa ukunamathela kumathuluzi, ukwenza ukwakhiwa kube lula, futhi kunciphise ukuzikhandla ngokomzimba kwabasebenzi.

3. Okuqukethwe kwebhamuza

Okuqukethwe kwebhamuza lomoya okuphezulu kubangela isivuno esingcono sodaka nokusebenza, kunciphisa ukwakheka kokuqhekeka.Iphinde yehlise inani lokushuba, okuholela entweni "ye-liquefaction".Okuqukethwe kwebhamuza lomoya ngokuvamile kuncike esikhathini sokunyakazisa.Imikhiqizo isetshenziswa kabanzi ukwenza ngcono ukusebenza kwezinto zokwakha ezisebenza nge-hydraulic, njengosimende negypsum.Ezisimendeni ezenziwe usimende, kuthuthukisa ukugcinwa kwamanzi, kwandisa ukulungiswa kanye nezikhathi ezivulekile, futhi kunciphisa ukuwohloka.

4. Anti-sagging

Udaka oluhle olungancibiliki lusho ukuthi uma lusetshenziswa ezingqimbeni eziwugqinsi ayikho ingozi yokucwila noma ukugeleza okuya phansi.Ukumelana ne-Sag kungathuthukiswa ngokwakhiwa okuqondile kwe-hydroxypropyl methylcellulose.Ikakhulukazi i-hydroxypropyl methylcellulose esanda kwakhiwa inganikeza izakhiwo ezingcono zokunqanda ukucwiliswa kodaka.

5. Ikhono lokumanzisa

Imikhiqizo efanelekile ye-cellulose ether ingathuthukisa i-viscosity yodaka ngenkathi iqinisekisa umsebenzi ongaphezulu kanye nokunamathela okumanzi kodaka, okwenza udaka lube nokusebenza okungcono ekumanziseni i-substrate, noma ngabe isetshenziswa ku-EPS noma i-XPS, njll. akukho ukugoqa nokungamanzisi endaweni eyisisekelo ekhethekile.
