IHydroxypropyl Methylcellulose (HPMC yamafuphi) iyi-ether ebalulekile exubile, eyi-polymer engenawo amanzi, futhi isetshenziswa kabanzi ekudleni, embonini yamakhemikhali, ukukhishwa kwe-polymerization kanye nokwakha njengokumiswa kokusakazwa, ukuqina, I-emulsible, eqinisa nokunamathela, njll., Futhi kukhona igebe elikhulu emakethe yasekhaya.
I-Hydroxypropyllylyly isetshenziswa kabanzi embonini yezokwakha njenge-ejenti eyakha amafilimu, i-binder, i-stabilizer, umgqugquzeli wamanzi, njll., Njll.
Hydroxypropylmethylcellellulose
Igama eligcwele lesiNgisi: I-Hydroxypropyll methyl cellulose English ABzwisiation: HPMC
Ngoba i-HPMC inezakhiwo ezinhle kakhulu njengokuqina, i-emulsation, amafilimu okwakha, ukuvikela i-colloid, ukushesha kwe-polymeric, izindwangu zokwakha, izindwangu, izindwangu, izindwangu, izindwangu, Ama-ceramics asetshenziswa nsuku zonke, amadivaysi kagesi nembewu yezolimo neminye iminyango.
Izinto zokwakha
Ezintweni zokwakha, i-HPMC noma i-MC imvamisa ingezwe ku usimende, ngodaka, nodaka ukuze kuthuthukiswe izakhiwo zokwakha nezokugcinwa kwamanzi.
Ingasetshenziswa njenge:
1). I-ejenti yokunamathela ne-caulking ye-gypsum esekelwe ekunamatheleni;
2). Ukubopha izitini ezenzelwe usimende, amathayili nezisekelo;
3). I-stucco esekwe eceleni;
4). Uhlamvu lwesakhiwo olususelwa kusosimende;
5). Kwifomula yokupenda nopende remover.
Anamathela amathayili we-ceramic
Hpmc 15.3 izingxenye
Perlite 19.1 izingxenye
Amafutha ahlanza futhi ama-cyclic thio ahlanganisa izingxenye ze-2.0
Clay 95.4 izingxenye
Isizini le-silica (22μ) izingxenye ezingama-420
450.4 Izingxenye zamanzi
Kusetshenziswe usimende oboshwe ngezitini ezingaphakathi, amathayili, amatshe noma usimende:
Hpmc (degree degree 1.3) izingxenye ze-0.3
Cattelan usimende 100 izingxenye
I-Silica Sand 50 Izingxenye
Izingxenye ezingama-50 zamanzi
Kusetshenziswe njengesengezo sesakhiwo sokwakha esiphakeme kakhulu:
Cattelan usimende 100 izingxenye
Izingxenye ze-asbestos 5
I-Polyvinyl Alcohol Rood 1 Ingxenye
I-calcium milicate eziyi-15 izingxenye
Clay 0.5 izingxenye
Izingxenye ezingama-32 zamanzi
HPMC 0.8 izingxenye
Umkhakha Wokupenda
Embonini yepende, i-HPMC isetshenziswa kakhulu ku-Latex Paint kanye nezakhi zopende zamanzi ze-resin ze-resin njenge-ejenti eyakha amafilimu, isikhulisi, i-emulsifier ne-stabilizer.
Ukumiswa kwe-polymerization ye-PVC
Inkambu enokusetshenziswa okukhulu kakhulu kwemikhiqizo ye-HPMC ezweni lami ukumiswa kwe-polymerization ye-vinyl chloride. E-polymerization yokumiswa kweVinyl Chloride, uhlelo lokuhlakazeka luthinta ngqo ikhwalithi ye-PVC Resin yomkhiqizo kanye nokusebenza kwayo nemikhiqizo; Kungathuthukisa ukuqina okushisayo kwe-resin futhi kulawule ukusatshalaliswa kosayizi wezinhlayiyana (okungukuthi, lungisa ubuntu be-PVC). Inani lama-akhawunti we-HPMC ka-0.025% ~ 0.03 wokukhipha i-PVC%.
I-PVC Resin elungiselelwe yi-HPMC esezingeni eliphakeme, ngaphezu kokuqinisekisa ukuthi ukusebenza kuhlangabezana nezinga likazwelonke, futhi kunezakhiwo ezinhle zomzimba, izici ezinhle kakhulu zezinhlayiyana kanye nokuhleleka okuhle kwe-bhethe kahle.
Enye Imboni
Eminye imikhakha ifaka phakathi izimonyo ikakhulukazi, ukukhiqizwa kawoyela, okokuhlanza, ubuciko bezindlu kanye nezinye izimboni.
Amanzi ancibilikayo
I-HPMC ingenye yama-polymers ancibilikayo, futhi i-solubility yayo yamanzi ihlobene nokuqukethwe kwe-methoxyl group. Lapho okuqukethwe kwe-Methoxyl Group kuphansi, kungachithwa ku-alkali eqinile futhi akunankinga ye-thermodynamic gelation. Ngokukhuphuka kokuqukethwe kwe-methoxyl, kuzwela kakhulu ukuvuvukala kwamanzi futhi kuncibilike nge-tallute alkali ne-alkali ebuthakathaka. Lapho okuqukethwe kwe-Methoxyl kungu> 38C, kungachithwa emanzini, futhi kungachithwa futhi kuma-hydrocarbons ane-halogenated. Uma kufakwa i-acid ye-period ku-HPMC, i-HPMC izohlakazeka ngokushesha emanzini ngaphandle kokukhiqiza izinto zokukhokha ezingafakwanga. Lokhu kungenxa yokuthi iqiniso lokuthi i-acid yesikhathi inamaqembu e-dihydroxyl endaweni ye-ortho ku-glycogen ehlakazekile.
