Ukwakhiwa kwe-HPMC ekwakheni nasekupekeni

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.

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.

BIzinto zokwakha

Ezintweni zokwakha, i-HPMC noma i-MC imvamisa ingezwe ku usimende, ngodaka, nodaka ukuze kuthuthukiswe izakhiwo zokwakha nezokugcinwa kwamanzi.

I-HPMC 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% wokukhishwa kwe-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.

OUmkhakha Wezempilo

Eminye imikhakha ifaka phakathi izimonyo ikakhulukazi, ukukhiqizwa kawoyela, okokuhlanza, ubuciko bezindlu kanye nezinye izimboni.

WI-ater incaluble

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.
