Kwiminyaka yakutshanje, ngokuphuhliswa okuqhubekayo kwetekhnoloji yodonga lwangaphandle, inkqubela phambili yeTekhnoloji yeSelupolose, kunye neempawu ezintle ze-HPMC ngokwayo, i-HPMC isetyenziswe ngokubanzi kwishishini lokwakha.
Ukwenzela ukuphinda uphonononge indlela yesenzo senyathelo phakathi kwe-HPMC kunye neZixhobo esekwe kwiSanti, eli phepha ligxile kwiziphumo zoPhuculo lwe-HPMC kwiipropathi ezihlanganisiweyo zesamente.
ixesha lokuvula
Ixesha lokuseta ikhonkrithi linxulumene ikakhulu kwixesha lesamente, kwaye i-aggregate inefuthe elincinci, ngenxa yoko ukucwangciswa kwe-HPMC kwixesha lokuthengiswa kwe-HPMC, kuba kufuneka kulungiswe i-HPMC kwi-quatio yesamente yodaka.
Ngokutsho kovavanyo, ukongezwa kwe-HPMC kunesiphumo esibonakalayo sokuntywila kodaka, kunye nexesha lokufakelwa koludaka ngokulandelelana ngokunyuka komxholo we-HPMC. Ngaphantsi komxholo ofanayo we-HPMC, umanzi ophantsi kwamanzi abunjiweyo uphakame ngokukhawuleza kunodaka lwendalo. Ixesha lokuhlala eliphakathi lide lide. Xa ilinganiswa emanzini, xa kuthelekiswa nenqaku elingenanto, ixesha lokumiselwa kwe-HPMC lilibazisekile ngeeyure ezingama-6 ukuya kweli-18 zokuseta okokuqala kunye neeyure ezingama-6 ukuya kwezi-2 zokuseta okokuqala. Ke ngoko, i-HPMC kufuneka isetyenziswe ngokudibeneyo kunye nee-aclerators.
I-HPMC yipolly yemolekyuli ephezulu kunye neqela le-macromolecular kunye neqela le-hydroxyl kwiqela elisebenzayo, elinokwenza iimolethi ze-hydrogen ngokuxuba iimolekyuli zamanzi kunye nokunyusa i-viscosity yamanzi okuxuba. Iimolekyuli ezinde ze-HPMC ziya kutsalane, zenza iimolekyuli ze-HPMC zidibanisa kunye nezinye izinto zokwenza isakhiwo senethiwekhi, sisonga isamente kunye nokudibanisa amanzi. Ukususela kwi-HPMC yendlela yenethiwekhi efana nefilimu kwaye isongela isamente, iya kuthi inqande ngokuphumelelayo ukungcungcutheka kwamanzi elulambo, kwaye ithintele umgangatho we-qumeration yesamente.
Ukopha
I-phenomeno eyophalaza i-dunon ifana neyo yekhonkrithi, eya kuthi ibangele indawo yokuhlala enkulu, ekhokelela ekunyukeni kweplastiki ye-quarry, kwaye iqhekeza, kunye namandla omphezulu obuthathaka.
Xa idosi ingaphezulu kwe-0.5%, ngokusisiseko sobuso. Kungenxa yokuba i-HPMC ixutywe nodaka, i-HPMC iqulunqe ifilimu kunye nolwakhiwo lwenethiwekhi, kunye ne-adsorvo yamaqela e-hydroleyl yenza isamente kunye nokudibanisa isakhiwo esihleweyo sodaka. Emva kongeza i-HPMC kudaka, kuya kwenziwa amaqamli amaninzi amaqamji amaninzi. Ezi gubble zomoya ziya kuhanjiswa ngokoludaka kwaye zithintele i-repotion ye-aggregate. Intsebenzo ye-HPMC inefuthe elikhulu kwizinto ezisekwe kwizinto ezisisiseko, kwaye ihlala isetyenziselwa ukulungiselela izinto ezintsha ezinobungozi ezifana nodaka lomgubo kunye nokugcinwa kwamanzi kakuhle.
Ibango lamanzi omdaka
Xa inani le-HPMC lincinci, linempembelelo enkulu kwimfuno yamanzi odaka. Kwimeko yokugcina inqanaba lokwandiswa kombhobho omtsha ngokusisiseko, ngokomxholo we-HPMC kunye nemfuno yamanzi kunye nemfuno yamanzi kulwalamano oluthile, kwaye imfuno yamanzi yodaka iyancipha kwaye inyuke ngokunjalo. Xa isixa se-HPMC singaphantsi kwe-0.025%, ngokunyuka kwenani, imfuno yamanzi yodaka iyancipha phantsi kwe-HPMC, inomphumo wokunciphisa amanzi kudaka, kwaye i-HPMC inesiphumo sokungena komoya. Inani elikhulu lamaqamza amancinci omoya ozimeleyo eluphangweni, kwaye la maqabu ahlala asebenza njengeoyile ukuphucula ubulwele bodaka. Xa idosi ingaphezulu kwe-0.025%, imfuno yamanzi yodaka inyuka inyuka idosi. Kungenxa yokuba ubume benethiwekhi ye-HPMC bugqityiwe, kwaye umsantsa phakathi kwe-flocs kwi-molecular ye-molecular ivunyelwe, enesiphumo sokutsala kunye nokudibanisa, kwaye kunciphisa ubulwele bodaka. Ke ngoko, phantsi kwemeko apho inqanaba lokwandiswa ngokusisiseko, isilayidi sibonisa ukwanda kwemfuno yamanzi.
I-01. Ukusasazwa kokunyangwa:
Ukuhlaselwa okuchasene nesalathiso esibalulekileyo sobugcisa ukulinganisa umgangatho wearhente ye-anti-ukusasazeka. I-HPMC yi-polymer ye-polymer yamanzi, ebizwa ngokuba yi-relin enyibilikisi okanye i-polymer ye-folymer. Iyonyusa ukungqinelana komxube ngokwandisa i-viscomosity yamanzi okuxuba. Yinto ye-hiddrophilic pollymer enokunyibilika emanzini ukwenza isisombululo. okanye ukusasazeka.
Iimvavanyo zibonisa ukuba isixa senani le-NAPHTHHALE-isekwe kwi-Superplaizer ePhezulu, ukongezwa kwe-superplastikizer kuya kunciphisa ukusasazeka kokunganyangeki kwesamente exubeneyo. Kungenxa yokuba i-Naphthalene esekwe kwi-Naphthalene Eneration Right inciphise i-surfacnt. Xa amanzi edityanisiwe kudaka, umgangatho wamanzi uya kugxininiswa kumphezulu wamasuntswana e-cele ukwenza umphezulu wesuntswana lwesamente linentlawulo efanayo. Oku kurhoxiswa ngombane kwenza amasuntswana e-cengsen enze ubume bokubhalwa kwesamente kuyadinwa, kwaye amanzi asongelwe kwisakhiwo sikhutshiwe, esiya kuthi senze ilahleko yenxalenye yenxalenye yesamente. Kwangelo xesha, kufunyaniswe ukuba ngokunyuka komxholo we-HPMC, ukusasazeka kokunganyangeki kwesamente yesamente kuya kuba ngcono kwaye kube ngcono.
I-02. Amandla eempawu zekhonkrithi:
Kwiprojekthi yelinge lesiseko, i-HPMC yangaphantsi kwamanzi angasasaziweyo yasetyenziswa, kwaye iBakala lamandla oYilo yayiyi-C25. Ngokutsho kovavanyo olusisiseko, inani lesamente lingama-400kg, i-slica i-slica i-25kg / i-HPMC i-0.42, i-Subre-ratiment yexabiso lesamente yi-8% yamandla angama-28d yekhonkco kwikhonkrithi yekhonkrithi Umoya yi-42.6MPA, amandla angama-28D ophakathi kwekhonkrithi yekhonkrithi ye-60mm ngu-36.4MPA, kunye nomyinge wamandla owenziwe ngekhonkrithi owenziweyo yi-84.8%, impembelelo ibaluleke kakhulu.
I-03. Iimvavanyo zibonisa:
(1) ukongezwa kwe-HPMC kunefuthe elibonakalayo kumxube ongumdaka. Ngokwanda kwemixholo ye-HPMC, ixesha lokumiselwa lidluliselwe ngokulandelelana. Ngaphantsi komxholo ofanayo we-HPMC, udaka oluwayo phantsi kwamanzi lukhawuleze kunelo luyekwe emoyeni. Ixesha lokuhlala eliphakathi lide lide. Eli nqaku liyingenelo kwikhonkrithi yekhonkrithi yangaphantsi.
.
(3) Isixa se-HPMC kunye nemfuno yamanzi yobukhoboka
.
. I-piment yenziwe phantsi kwamanzi kangangeentsuku ezingama-28 icrisp encinci. Esona sizathu kukuba ukongezwa kwe-HPMC kunciphisa kakhulu ilahleko kunye nokusasazeka kwesamente xa kuthulule emanzini, kodwa kunciphisa ukwenziwa kwelitye lesamente. Kwiprojekthi, phantsi kwemeko yokuqinisekisa ukusebenza okungasasazwanga phantsi kwamanzi, umthamo we-HPMC kufuneka uncitshiswe kangangoko kunokwenzeka.
. Iprojekthi yokulinga ibonisa ukuba umyinge wamandla wekhonkrithi esenziwe ngamanzi kunye nekhonkrithi eyenziwe ngomoya yi-84.8%, kwaye isiphumo sibaluleke kakhulu.
