Intshayelelo kwi-HPMC yeBanga lezeMveliso

1. Yintoni i-HPMC yoBuchule boShishino

Ibanga lezeMvelisoI-HPMC (iHydroxypropyl Methylcellulose)yi-non-ionic cellulose ether derivative, edla ngokuba yi-powder emhlophe okanye emthubi kancinci. Yenziwe ngeefayibha zekotoni zendalo ngokusebenzisa unyango lwe-alkali kunye nothotho lwee-chemical reactions (ezifana ne-etherification), kwaye ihambelana kakuhle ne-biocompatibility kunye nozinzo lweekhemikhali. Ngenxa yeempawu zayo ezizodwa zomzimba nezekhemikhali, i-HPMC isetyenziswa kakhulu kwiindawo ezininzi zoshishino ezifana nokwakha, ukugquma, iiseramikhi, kunye neekhemikhali zezolimo.

2. Ukusebenza Okuphambili kwe-HPMC yoBuchule boShishino

Ukujiya

I-HPMC inamandla abalaseleyo okutyeba kwaye inokunyusa ngempumelelo ukutyeba kwenkqubo yolwelo, ngaloo ndlela iphucula ulwakhiwo, ukutyibilika kunye neempawu zokuxubha zemveliso.

Ukugcinwa Kwamanzi

Kwizicelo ezifana nodaka kunye ne-putty, i-HPMC inokuphucula kakhulu ukugcinwa kwamanzi kwezinto, ithintele ukulahleka kwamanzi ngokukhawuleza, yandise ixesha lokusebenza, kwaye iphucule uxinano kunye nokunamathela kwemveliso egqityiweyo.

Ukwenziwa kweeFilimu

I-HPMC inokwenza ifilimu eqinileyo necacileyo phezu komphezulu, inika imveliso iipropati ezilungileyo zokukhusela kunye nokukhazimla.

Ukusasazeka kunye nokuxutywa kwe-emulsification

I-HPMC inokusasazeka kakuhle emanzini kwaye ingasetyenziswa njenge-emulsifier ukuzinzisa inkqubo kunye nokuphucula ukuhambelana kunye nokuzinza kwefomyula.

I-gelation yobushushu

Isisombululo samanzi se-HPMC siya kwenza ijeli xa ishushu ukuya kubushushu obuthile. Le propati yejeli eguqulwayo ixabiseke kakhulu kwezinye iinkqubo ezikhethekileyo.

3. Iindawo eziphambili zesicelo se-HPMC yezinga lemizi-mveliso

Ishishini lokwakha

I-mortar exutywe ngomileyo (efana ne-tile adhesive, i-plaster mortar, i-self-leveling mortar): I-HPMC inokuphucula ukugcinwa kwamanzi, ukunamathela kunye nokusebenza kokwakhiwa kwe-mortar.

Umgubo wePutty: Phucula indlela oziva ngayo ulwakhiwo, uthintele ukuqhekeka nokudumba, kwaye uphucule umgangatho womphezulu wemveliso egqityiweyo.

Inkqubo yokukhusela ubushushu yangaphandle (i-EIFS): Yonyusa ukunamathela kunye nokuguquguquka kwesamente kwaye yandisa ukuqina.

Ishishini lepeyinti

I-HPMC isetyenziswa njenge-thickener, i-stabilizer kunye ne-film yangaphambili ukuphucula ukusebenza kwe-anti-wagging, i-can yokuvula uzinzo kunye ne-film efanayo yokwaleka.

Ishishini le-ceramic

Kwimveliso yeembumba zeseramikhi, i-HPMC idlala indima ekugcinweni kwamanzi, ukuthambisa, ukubumba, njl.njl., inceda ekuphuculeni uxinano kunye nokumelana nokuqhekeka kwemveliso.

Iimveliso zeekhemikhali zemihla ngemihla

Ukongeza i-HPMC kwizicoci nakwiisepha kunokunyusa ukuhambelana kwemveliso, kwenze i-foam ibe ncinci kwaye ihlale ixesha elide, kwaye kuphucule uzinzo lwefomyula.

Ukubhola ioyile

Njengesongezelelo solwelo lokugrumba, i-HPMC inokulungisa i-rheology yolwelo lokugrumba, ithintele ukudilika kodonga lomngxuma, kwaye iphucule ukusebenza kakuhle kokugrumba.

4. Indlela yokusebenzisa i-HPMC yodidi lwemizi-mveliso

Ngokwesiqhelo, i-HPMC kufuneka isasazwe emanzini abandayo ukuze yenze isisombululo esifanayo ukuze isebenze ngokupheleleyo. Amanyathelo aqhelekileyo okusetyenziswa ngala alandelayo:

Fafaza i-HPMC kancinci kwaye ngokulinganayo emanzini abandayo axutyiweyo ukuze uphephe ukuhlangana.

Qhubeka uvuselela de kube kusasazeka kwangaphambili.

Yima ixesha elithile (ngokubanzi ngaphezulu kweeyure ezi-2) ukuze unyibilikise i-cellulose ngokupheleleyo kwaye uyinyibilikise.

Ukuba kuyimfuneko, xuba ngononophelo de kubekho isisombululo esicacileyo okanye esikhanyayo esifanayo.

Kwimisebenzi yokwenyani yemizi-mveliso, ubungakanani be-HPMC eyongeziweyo ngamanye amaxesha buhlengahlengiswa njengoko kufuneka, ngokubanzi bulawulwa phakathi kwe-0.1% kunye ne-2.0%, kwaye umlinganiselo othile uxhomekeke kwinkqubo yefomula kunye nesiphumo esifunekayo.

5. Ulawulo lomgangatho kunye nesalathiso sokukhetha

I-HPMC yodidi lwezemizi-mveliso ineenkcazo ezahlukeneyo ze-viscosity (ezifana ne-400 mPa.s, i-15000 mPa.s, njl.njl.) kunye nenqanaba lokutshintsha (oko kukuthi inqanaba lokutshintsha i-hydroxypropyl kunye ne-methyl) ngokweemfuno ezahlukeneyo zesicelo. Ukukhetha imodeli efanelekileyo kunempembelelo ebalulekileyo ekusebenzeni kwemveliso. Izinto zovavanyo eziqhelekileyo ziquka:

Ukuqina (isisombululo se-2% kubushushu begumbi)

Ubungakanani bokufuma

Umxholo wothuthu

Umxholo weMethoxy kunye neHydroxypropyl

ixabiso le-pH (isisombululo samanzi esingu-1%)

I-HPMC yomgangatho ophezulu wemveliso kufuneka ibe neempawu zomlotha ophantsi, ukusasazeka kakuhle, ukuxinana okuzinzileyo, kunye nesantya sokunyibilika ngokukhawuleza.

6. Ukugcinwa kunye nokupakishwa

I-HPMC kufuneka igcinwe kwindawo epholileyo, eyomileyo, enomoya ococekileyo, iphephe ubushushu obuphezulu, ukufuma kunye nokukhanya kwelanga ukuthintela ukufunxwa komswakama, ukuhlangana okanye utshintsho lokusebenza. Ihlala ipakishwa kwiingxowa zephepha ezidityanisiweyo ezinamalaya amaninzi ezifakwe iingxowa zefilimu ze-polyethylene. Imigaqo eqhelekileyo yokupakishwa yi-25 kg/ingxowa, enokuthi yenziwe ngokwezifiso ngokweemfuno zabathengi.

I-HPMC yezinga lezemizi-mvelisoIdlala indima engenakutshintshwa kwiindawo ezininzi zoshishino ngenxa yeempawu zayo ezibalaseleyo zomzimba nezekhemikhali. Ngokukhula kwezixhobo zokwakha eziluhlaza, iingubo ezinobuhlobo nokusingqongileyo kunye nezixhobo ezidityanisiweyo ezisebenzayo, imfuno ye-HPMC esemgangathweni ophezulu nayo iyanda. Kwixesha elizayo, ngokuphuculwa okuqhubekayo kweenkqubo zemveliso kunye nokwandiswa kweendawo zokusetyenziswa, i-HPMC yomgangatho wezoshishino iya kubonisa ithuba elibanzi lophuhliso.
