Hydroxypropyl methylcelceluplose hpmc eqhelekileyo

1. Yeyiphi eyona njongo ye-HPMC?

Le mveliso isetyenziswa njenge-thi checkerer, isisasazi, isibophelelo, i-fistleng, i-oyile enganyangekiyo, i-filler, i-filler, i-mulsifier kunye nokuzinzisa kwishishini lekhompyuter. Kukwasetyenziswa ngokubanzi kwi-wilthhetic ye-wistlin, i-petrochemical, i-ceramic, iphepha, isikhumba, iyeza, ukutya kunye nemizi-mveliso ye-cosmetics.

2. Iyintoni indima ye-HPMC kudonga lwangaphakathi lwe-interty powder?

I-HPMC inemisebenzi emithathu: i-posty powder yodonga lwangaphakathi, ukuqina, ukutshixa kwamanzi kunye nokwakha amanzi kunye nokwakha amanzi kunye nokwakha amanzi. Uxinzelelo: I-Methyl Selelose inokujongwa ngokutsala okanye isisombululo esibonakalayo sokugcina izinto ezifanayo kunye nemisebenzi engaguqukiyo kunye nokuthintela ukuhamba kunye nokuxhonywa. Ukutshixa kwamanzi: I-powder yodonga ingaphakathi iyothusa kancinci, kwaye i-calcium ye-lime ibonakaliswa ekusebenziseni amanzi. Ulwakhiwo lwezoBunjineli I-HPMC ayithathi nxaxheba kutshintsho lwazo zonke iichemicals, kodwa zithatha inxaxheba kwinguqulelo yokugcwalisa. Udonga lwangaphakathi I-Pollty Powder, eludongeni, lutshintsho lwekhemikhali, kuba kukho iPhemikhali entsha, udonga olungaphakathi ususwe eludongeni, olinyiweyo, ngenxa yokuba ivelisiwe. Amacandelo aphambili e-Grey Calcium Powder yile: umxube we-CA ungathathi nxaxheba kuyo nayiphi na impendulo ngokwayo.

3. Ungawugweba njani umgangatho we-HPMC ngokulula nangokuthathekayo?

. Nangona kunjalo, iimveliso ezilungileyo zinobumnyama obuhle. . Ukulungisa ubuhle, kungcono ngokubanzi. . Owona msebenzi mkhulu, engcono, ebonisa ukuba kukho ukungavumi ngaphakathi. . Ukutshintsha kwesakhelo esithe nkqo kuhle, kwaye i-proctor ethe tyaba imbi kakhulu, kodwa ayithethi ukuba umgangatho wesakhiwo esithe nkqo ulunge ngakumbi kuneso se-reactor ethe tyaba. Umgangatho wemveliso usamiselwa zizinto ezininzi. . Ubunyani obuphezulu bubangelwa yi-hydroxypropy ephezulu kuyo, kwaye uphakame umxholo we-hydroxypropy, kungcono ukugcinwa kwamanzi.

4. Yintoni ekufuneka ithathelwe ingqalelo xa usebenzisa i-viscofity kunye neqondo lobushushu le-HPMC?

Uhlobo lwe-HPMC lulinganayo ngokulinganayo amaqondo obushushu, oko kukuthi, i-viscosity inyuka njengoko ubushushu bokunciphisa. Sivame ukuba i-viscosity yemveliso ibhekisa kwiziphumo zovavanyo lwe-2% ye-acteous yeqondo lobushushu le-20 degrees Celsius. Kwizicelo ezisebenzayo, kwiindawo ezinomahluko wobushushu obukhulu phakathi kwehlobo nasebusika, kufuneka ziqatshelwe ukuba kuyacetyiswa ukuba usebenzise i-viscofity ephantsi ebusika, elungele ngakumbi ukwakhiwa. Ngaphandle koko, xa amaqondo obushushu aphantsi, uVekyusi weSelupolo uya kunyuka, isandla siya kuziva sinzima xa sikhutshiwe.

5. Zithini iindlela zokuchitha i-HPMC?

Indlela eshushu yokuphelisa amanzi Iindlela ezimbini eziqhelekileyo zichazwe ngolu hlobo lulandelayo: 1). Isixa samanzi ashushu kwaye sivuthelwe malunga nama-70 ° C. Ngokuthe ngcembe yongeza i-HydroxyPOpyl Methylcelgalose ecothayo, qala i-HPMC kumphezulu wamanzi, emva koko uphose i-slirry, kwaye upholile ngokutyibilikayo. 2). Yongeza i-1/3 okanye i-2/3 yenani elifunekayo lamanzi kwisitya kwaye sitshise ukuya kwi-70 ° C. Ngokwendlela ye-1), ukusasaza i-HPMC ukulungisa amanzi ashushu; Emva koko yongeza inani eliseleyo lamanzi abandayo ukuya kwamanzi ashushu kwi-slirry, upholile umxube emva kokuvuselela. Indlela yokudibanisa i-powder -Mpawuli wePlader kunye nabavelisi bodaka Sebenzisa le ndlela. [I-HydroxyPOpyl Methyl Selelose (i-HPMC) isetyenziswa njengearhente yokuthambisa kunye nokugcina amanzi kumda we-potty powder. ]

6. YintoniidosiI-HPMC yongezwa kwi-podty powder?

Isixa se-HPMC esetyenziswa kwezicelo eziyinyani ziyahluka ngokuxhomekeke kwimozulu, ubushushu, umgangatho we-Ash Calcium ongu-Ash, ifomula ye-poty powder, kunye "nomgangatho ofunwa ngabathengi". Ngokubanzi, uphakathi kwe-4 kg kunye ne-5 kg. Umzekelo, umgubo obekwe ngumhombiso '> I-Beijing ubukhulu becala i-5 kg; Umgubo obekwe i-setty e-Guizhou ubukhulu becala i-5 kg ​​ehlotyeni kunye ne-4.5 kg ebusika; Imali eyongeziweyo kaYunnan incinci, ngokubanzi i-3 kg-4 kg njalo njalo.
