I-Hydroxypropyl Methylcelcelose inokuphucula ukuchitheka kwesamente yesamente

I-Hydroxypropyl Methylcelcelgalose yi-Polymer Polymer ye-Polymer ye-Polymer, ekwabizwa ngokuba yi-relin enyibilikayo okanye i-polymer ye-flaymer. Iphuma umxube ngokwandisa i-viscomosity yamanzi okuxuba. Yinto ye-hydrophilic pollymer. Ingachithwa emanzini ukwenza isisombululo okanye ukusasazeka. Iimvavanyo zibonisa ukuba inani lexabiso le-Naphthalene-Superplaisticiezer linyuswa, ukubandakanywa kwe-Superpasticiezer kuya kunciphisa ukusasazeka kokunganyangeki kwesamente exubeneyo. Kungenxa yokuba i-Naphthalene Superplaistiber yi-surfacnt. Xa iarhente encitshiswa kwamanzi yongezwa kudaka, iarhente encitshiswa kwamanzi icwangciswe kumphezulu wamasuntswana wesamente, ukuze umphezulu wezinto ezinesamente unetyala elinye. Oku kurhoxiswa ngombane kuhlasela isakhiwo seentyatyambo ezenziwe ngamasuntswana, kwaye amanzi asongelwe kwisakhiwo siyakhululwa, esikhokelela ekuphulukaneni nenxalenye yenxalenye yenxalenye yenxalenye yenxalenye yenxalenye yenxalenye yenxalenye yenxalenye yesamente. Kwangelo xesha, kwafunyaniswa ukuba ngokunyuka komxholo we-HPMC, ukusasazeka kokunganyangeki kwesamente yesamente esitsha kuye kwaba ngcono kwaye kungcono.

Amandla ePropathi yeKhonkrithi:

I-HPMC yangaphantsi kwe-HPMC engafakwanga i-Diswmagete isetyenziswe kwi-ridge yendlela yobunjineli besizwe sendlela yobunjineli besiseko, kunye namanqanaba amandla oYilo yi-C25. Ngokutsho kovavanyo olusisiseko, inani lesamente lingama-400kg, inani le microsilica liyi-25kg / m3, isixa se-HPMC siyi-0.6% yexabiso lesamente, umlinganiselo wesanti ngama-40%, kwaye imveliso ye-Naphthyl Superplaistiber yi-8% yexabiso lesamente. , Iisampulu zekhonkrithi emoyeni iintsuku ezingama-28 zinamandla aqhelekileyo e-42.6MPA, kunye nekhonkrithi egalelwe ngaphantsi kwamanzi kangangeentsuku ezingama-60 nge-60.4 MPA.

1. Ukongezwa kwe-HPMC kunefuthe lokugcina ngokucacileyo kumxube wokuxoka. Ngokwanda kwemixholo ye-HPMC, ukuseta ixesha lokutsalwa ngokuthe ngcembe. Ngaphantsi komxholo ofanayo we-HPMC, udaka oluziimpingo lwaphantsi kwamanzi lungcono kunodaka oluwenziwe emoyeni. Ixesha lokuqina lokubumba lide. Eli nqaku liququzelela phantsi kwamanzi athambileyo.

I-2. Ukungcola okutsha kwesamente

3. Umxholo we-HPMC kunye nemfuno yamanzi yobukhoboka kancitshisiwe okokuqala kwaye kwanda kakhulu.

4. Ukufakwa kwe-arhente yokunciphisa amanzi kuphucula ingxaki yokunyuka kwemfuno yodaka, kodwa kufuneka kulawulwe ngokuvakalayo, kungenjalo kuya kungenjalo ngamanye amaxesha kuya kunciphisa ukusasazeka kwamanzi okuxubeneyo.

5. Kukho umahluko omncinci kwisakhiwo sesamente ixutywe ne-HPMC kunye ne-Supemen engenanto, kwaye kukho umahluko omncinci kwisakhiwo kunye nokuxinana kwesamente ekutsaleni amanzi kunye nomoya. Isampuli esetyenzisiweyo emva kweentsuku ezingama-28 phantsi kwamanzi zikhululekile kancinci. Esona sizathu kukuba ukongezwa kwe-HPMC kunciphisa kakhulu ilahleko kunye nokusasazeka kwesamente ngexesha lokugabha emanzini, kodwa kunciphisa ukungcola kwelitye lesamente. Kwiprojekthi, isixa se-HPMC kufuneka sincitshiswe kangangoko kunokwenzeka ngelixa siqinisekisa isiphumo sokungathobeki phantsi kwamanzi.

6. Umdibaniso we-HPMC yangaphantsi kwamanzi angafikelelekiyo, ulawulo lwesixa-mali lulungele amandla amakhulu. Iiprojekthi zokulinga zibonise ukuba ikhonkrithi eyenziwa emanzini inomyinge wamandla angama-84.8% eyenziweyo emoyeni, kwaye impembelelo ibaluleke nangakumbi.
