Kuzvimiririra pachako mongwe kunogona kuvimba nehuremu hwayo kuumba iyo flat, yakatsiga uye yakasimba nheyo pane iyo substrate yekuisa kana kuumba zvimwe zvinhu. Panguva imwecheteyo, inogona kuita yakakura-yakawanda uye inoshanda kuvaka. Naizvozvo, kukunda kwakakwirira chinhu chakakosha kwazvo chekuzvimiririra pachako mukuwedzera, chinofanira kuve nekumwe kuchengetwa kwemvura uye kushamwaridzana kwemvura, hapana husimbiso dzemvura, uye vane hunhu hwekupisa kupisa uye kupisa kwakadzika kusimuka.
Kazhinji, kuunganidza mauto kunoda kuti utsi hwakanaka, asi iyo fluidity yeiyo chaiyo coment paste inowanzo kungoita 10-12cm; Pakati pevaCellulose eva Cellulose, hpdropropyl methylcellose (HPMC) chikamu chikuru chakagadzirirwa, chinogona kuvandudza kuwirirana, kuita basa rekuita, kuita basa rekuita uye kudzokorora kwemvura. Iyo inotora basa rakakosha kwazvo mumunda weDhivha yakagadzirirwa-yakavhenganiswa.
1. Mobility
HydroxyPropyl methylcellose (HPMC) ine yakakosha pesvedzero pakuchengetwa kwemvura, kusakwana uye kuita kwekuvaka kwekuzvienzanisa. Kunyanya seyakaizvikudza dolder, fluidity ndeimwe yezviratidzo zvikuru zvekuongorora kuzvimiririra. Pasi pekutanga kweshanduro yakajairika yekuumbwa kweiyo mongwe, iyo fluidity yemutya inogona kugadziriswa nekuchinja huwandu hweHPMC. Nekudaro, kana iyo Dosi yakanyanya kukwirira, iyo svutugadzike inoderedzwa, saka dosage yeHPMC inofanira kudzorwa mukati meiyo runzwisisika.
2. Kuchengeta mvura
Kuchengetwa kwemvura kwemutya idanho rakakosha kuyera kugadzikana kwezvinhu zvemukati zvezvikamu zvitsva zvakasanganiswa. Kuti vaite zvizere maitiro ehystem yezvinyorwa zveGel, huwandu hwakaringana hweHPMC hunogona kuchengetedza hunyoro mumutumbi kwenguva yakareba. Kazhinji, iyo mvura yekuchengetwa kwemvura yekuwedzera inowedzera nekuwedzera kweHPMC zvemukati. Kuchengetwa kwemvura kweHPMC kunogona kudzivirira iyo substrate kubva mukukora mvura yakawandisa nekukurumidza, uye kukanganisa mvura yemvura, kuitira kuti ive nechokwadi chekuti nzvimbo yakakwana inopa mvura yakakwana yeiyo skment hydration. Uye zvakare, iyo visikopa ye hydroxyprupyl methylcellose ine pesvedzero huru pakuchengeta kwemvura. Iyo yepamusoro viscosity, zvirinani kuchengetwa kwemvura. Kazhinji, zvigadzirwa zvine zvevasangano zvevakanaka zvevakanaka
3. Kugara nguva
HPMC ine imwe yekudzosera mari pane dhaka. Nekuwedzera kweiyo dosage, nguva yekugara yomutema inogara kwenguva refu. Iko kudzoreredzwa kweHPMC pane siment paste inonyanya kuenderana neiyo degree rekutsiva mapoka eAlkyl, uye ine hukama hwacho husina huremu hwayo hwakanaka. Iyo diki iyo degree reAlkyl kutsiva, iyo yakakura iyo hydroxyl yezvinyorwa, uye zvakanyatsojeka maitiro ekudzosera. Uye yakakwira iyo HPMC zvirimo, iyo iri pachena mhedzisiro yeiyo yakaoma firimu danda pane yekutanga hydration kudzoka kwesimendi, saka maitiro ekudzoserazve zvakare zviri pachena.
4. Simba rinoshanduka-shanduka uye simba rekumanikidza
Kazhinji, Simba ndeimwe yeiyo yakakosha yekuongorora indekisi yekuporesa mhedzisiro yezvinhu zvemasimendi zvekushandisa pane musanganiswa. Simba rekumanikidza uye simba rinosindimara resimba remutya richadonha nekuwedzera kweHPMC zvemukati.
5. Bond Simba
HPMC ine pesvedzero huru pakubata kwemutengesi. HPMC inoumba firimu rePolymer ine chisimbiso pakati peiyo simende system uye inosimudzira mvura yakawanda mufirimu kunze kwenyaya, iyo inokodzera kuhukura yeiyo simenti, nekudaro ichivandudza iyo slurry mhando. Simba rakaomeswa simba. Panguva imwecheteyo, achiwedzera huwandu hwakakodzera hweHPMC anowedzera plasticity uye kushanduka kwemutya, kuderedza kuomarara kwenzvimbo yekufambisa pakati pechidimbu uye iyo substrate interface, uye inoderedza mashandiro ekutsvedza pakati pemasangano. Kune imwe nhanho, kushamisika pakati pehudyu uye substrate inosimbiswa. Mukuwedzera, nekuda kwekuvapo kweHPMC muComent Paste, inokosha interface transition zone uye interface layer inoumbwa pakati peiyo motert scucles uye iyo hydration chigadzirwa. Iyi interface layer inogadzira iyo InterFACE Transition zone inochinja uye isinganyanye kuomarara. Naizvozvo, duri rine simba rakasimba kushamisika.
