I-Hydroxypropyl methyl cellulose (ngeresiphi)

I-Hydroxypropyl Methylcellulose (HPMC yamafuphi) iyi-ether ebalulekile exubile, okuyi-polymer engenawo amanzi, futhi isetshenziswa kabanzi njengokumiswa kokusakazwa, ukunamathela, i-polymerization reaction kanye nokwakhiwa, njll, futhi kunegebe elikhulu emakethe yasekhaya.

Hydroxypropylmethylcellellulose
Igama eligcwele lesiNgisi: I-Hydroxypropyll methyl cellulose English ABzwisiation: HPMC

Ngoba i-HPMC inezakhiwo ezinhle kakhulu njengokuqina, i-emulsication, amafilimu okwakha, ukufundwa okuvikelekile, ukukhiqizwa kwamafutha, izindwangu, izindwangu zokudla, izindwangu zezolimo kanye 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 ku:
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:
I-HPMC (degree of dispacesion 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.
