Imibuzo ebuzwa rhoqo malunga nokusetyenziswa kwe-hydroxypropyl methylcelcelce

Yintoni ukusetyenziswa kwe-hydroxypropyl methylceltulose?
Isetyenziswe ngokubanzi ngezinto zokwakha, iingubo, i-reatsins, i-ceramic, i-ceramics, i-cemaradi, ukutya, ibala, ezolimo, icuba kunye namanye amashishini. I-HPMC inokwahlulwa ibe: Ibanga lokwakha, iBanga lokutya kunye namayeza ngokwenjongo. Okwangoku, uninzi lweemveliso zasekhaya libakala lokwakha. Kwinqanaba lokwakha, isixa se-potty powder sikhulu kakhulu, malunga ne-90% isetyenziselwa umgubo ongezantsi, kwaye okuseleyo kusetyenziselwa ukuqina kwesamente kunye neglu.

Zeziphi iindlela zokuphelisa i-hydroxypropy ye-methyl fiber?
1. I-Hot All AMANZI AMANZI: UKUBA I-HPMC ayichithi njengamanzi ashushu, i-HPMC inokuba isasazeke ngendlela efanayo emanzini okuqala, emva koko ikhawuleza inyibilikisiwe.

2. Indlela yokuxuba i-powder: xuba i-HPMC POMDER enezinye izinto eziphezulu zemichiza, umxube ngokupheleleyo kwikona, kwaye emva koko inyibilike inyibilike, kwaye iya kunyibilika i-HPMC, kwaye iya kunyibilika ngokukhawuleza xa idibana kwangoko xa idibana kwangoko xa idibana nangoko.

Ungayikhetha njani i-viscosity ye-hydroxypropyl methylcelgulose?
Khetha ii-viscofis ezahlukeneyo ngokwezicelo ezahlukeneyo, ukusetyenziswa komgubo wokusela: Unokukhetha i-viscosity ye-100,000, into ebalulekileyo kukugcina amanzi ngcono. Ukusetyenziswa kodaka: Iimfuno eziphezulu, i-viscofity ephezulu, khetha i-viscosity ye-150,000. Ukusetyenziswa kweglue: Ufuna iimveliso ezikhawulezileyo, uVenkile okuphezulu, khetha i-viscosity 200,000.

Ungawubona njani umgangatho we-hydroxypropyl methylcelgulose?
Ubumhlophe: Nangona ubumhlophe bungaqali ukuba i-HPMC kulula ukuyisebenzisa, kwaye ukuba iarhente yomhlophe yongezwa kwinkqubo yemveliso, iya kuchaphazela umgangatho wayo. Nangona kunjalo, uninzi lweemveliso ezilungileyo lube mhlophe mhlophe.

Ukuhlelwa: Ukulunga kwe-HPMC yi-Mesh ye-80 Mesh kunye ne-100 Mesh, kunye ne-120 mesh incinci. Uninzi lwe-HPMC luveliswe eHebei yi-80 mesh. Ukuhlekisa kakuhle, ngcono.

Ukuhambisa: Beka i-hydroxypropyl methylcelcellulose (i-HPMC) emanzini ukwenza i-colloid engabonakaliyo, kwaye ujonge ukuhanjiswa kwayo. Ukufakwa kwe-verctoctor olwenziweyo kulungile, kwaye i-proctor ethe tyaba imbi kakhulu, kodwa ayinakuthethwa ukuba umgangatho wesakhiwo esithe nkqo ungcono kuneso sixhobo esithe nkqo, kwaye zininzi izinto ezimisela umgangatho wemveliso.

Ubuninzi obuthile: Kuyinto enkulu umxhuzulane othile, ubunzima obunzima. Ubuninzi obuthile bukhulu, kuba ngokubanzi kuba umxholo we-hydroxypropy kuwo uphakamile, kwaye umxholo we-hydroxypropy uphuphume, ukugcinwa kwamanzi kungcono.

Ubudlelwane phakathi kwe-viscofity kunye neqondo lokushisa ye-hydroxypropyl methylcelcelgalose
I-viscosity equacy ye-HPMC ihambelana ngokulinganayo kubushushu, oko kukuthi, njengoko iqondo lobushushu liyancipha, kwaye isisombululo se-2% sivavanywa kwi-20 degrees cymesi. Kwizicelo ezisebenzayo, kwiindawo ezinomahluko wobushushu obukhulu phakathi kwehlobo nasebusika, kufuneka kuqatshelwe ukuba i-viscofity esezantsi isetyenziswa ebusika, elungele ngakumbi ukwakhiwa.

Iyintoni indima ye-HPMC kwi-posty powder?
Kwimiphetho ye-setty, i-HPMC idlala imisebenzi emithathu: Ukugcinwa kwamanzi, ukugcinwa kwamanzi kunye nokwakha.

Ukutyibilika: I-SelelUlose inokuba ihlawulwe ukunqumamisa, gcina iyunifomu yesisombululo kwaye iyaguquka, kwaye iyaxhathisa.

Ukugcinwa kwamanzi: Yenza umgubo wokubekwa kancinci, kwaye uncede ukuphendula kwe-ASH Calcium phantsi kwesenzo samanzi.

Ulwakhiwo: I-Seleculose inefuthe lokunyathela, elinokwenza umgubo obekiweyo unokuphumelela. I-HPMC ayithathi nxaxheba kuyo nayiphi na indlela yokuphendula yemichiza kwaye idlala kuphela indima encedisayo. Ukongeza amanzi kwi-pople powder kwaye uyibeke eludongeni yindlela yokuphendula yemichiza. Ngenxa yokusekwa kwezinto ezitsha, thatha umgubo obekwe eludongeni eludongeni, gxotha ube ngumgubo, kwaye uphinde uyisebenzise. Ayizukusebenza, kuba izinto ezintsha (ze-calcium carbonate) zenziwe. ) phezulu) phezulu.

Amacandelo aphambili e-Ash Calcium Powder yile: umxube we-CA (oh) 2, i-Cao kunye ne-CAO SHIT ye-COHCIUM ye-CO2, i-CAO HOO = CO YORORCE kuphela I-calcium, kwaye ayithathi nxaxheba kuyo nayiphi na impendulo ngokwayo.
