Iyo Shrinkage Cracking yeKongiri ine hukama neHydroxypropyl Methylcellulose (HPMC)?

Shrinkage kupaza inyaya yakajairika mukuvaka kongiri uye inogona kuitika nekuda kwezvikonzero zvakasiyana. Chimwe chezvinogona kukonzera shrinkage kuparuka mukongiri kushandiswa kwehydroxypropyl methylcellulose (HPMC) sechinhu chinowedzera. HPMC inowanzoshandiswa mukongiri kuvandudza kushanda, kuchengetedza mvura, uye kukura kwesimba. Nekudaro, kushandiswa kweHPMC kunogona zvakare kutungamira mukupwanya kwekongiri mune mamwe mamiriro.

Chikonzero chikuru chekupwanya kwekongiri nekuda kweHPMC ndiko kudzikiswa kwehuwandu hwekurasika kwemvura. HPMC inochengetedza mvura inoshanda uye inogona kuderedza zvakanyanya mwero wekurasikirwa kwemvura kubva mukongiri nyowani. Zvisinei, mvura yakachengetwa inosunungurwa zvishoma nezvishoma nekufamba kwenguva, zvichiita kuti shrinkage uye kuputika kunotevera kwekrete.

Uyezve, zvimiro zveHPMC, senge huremu hwayo hwemamorekuru, dhigirii rekutsiviwa, uye kutarisisa, zvinogona zvakare kukanganisa shrinkage kupaza kwekongiri. HPMC ine huremu hwemamorekuru hwepamusoro uye dhigirii rekutsiva inogona kupa kuchengetedza kwemvura kuri nani uye kuderedza chiyero chekurasika kwemvura, nekudaro ichiwedzera mukana wekuputsika.

Uyezve, iko kusungirirwa kweHPMC mumusanganiswa wekongiri kunogona kukanganisawo dhigirii rekuputika kwe shrinkage. Kukwirira kwepamusoro kweHPMC kunogona kukonzera kuchengetwa kwemvura kukuru, izvo zvinogona kukonzera kuwedzera kuderera uye kuputika kunotevera.

Chimwe chinhu chinogona kubatsira mukupwanya kwekongiri nekuda kweHPMC mamiriro ekunze panguva yekurapa. Kupisa kwepamusoro uye hunyoro hushoma hunogona kukurumidzira chiyero chekurasika kwemvura kubva mukongiri itsva uye zvinotungamirira kukurumidza kupera uye kuputika.

Kudzikamisa njodzi yekupwanya kwekongiri nekuda kweHPMC, matanho akasiyana anogona kutorwa. Imwe sarudzo ndeye kushandisa HPMC ine yakaderera mamorekuru huremu uye dhigirii rekutsiviwa, izvo zvinogona kudzikisa simba rekuchengetedza mvura uye chiyero chekurasika kwemvura, nekudaro kuderedza mukana wekuputsika.

Imwe sarudzo ndeyekudzikamisa kusungirirwa kweHPMC mumusanganiswa wekongiri kudzivirira kuchengetedza kwemvura yakawandisa uye kuderera. Pamusoro pezvo, mamiriro ezvakatipoteredza panguva yekurapa, sekuchengetedza nharaunda ine hunyoro uye kudzora tembiricha, anogonawo kubatsira kudzikisa njodzi yekupwanya kwe shrinkage.

Mukupedzisa, kushandiswa kweHPMC mukongiri kunogona kutungamirira mukupwanya kwekuputika nekuda kwekuchengetedza mvura. Izvo zvimiro zveHPMC, senge mamorekuru huremu, dhigirii rekutsiva, uye kuisa pfungwa, pamwe nemamiriro ekunze panguva yekurapa, zvinogona kukanganisa dhigirii rekupwanya kwe shrinkage. Nekudaro, nematanho akakodzera, akadai sekusarudza HPMC ine zvivakwa zvakakodzera uye kudzora mamiriro ezvakatipoteredza, njodzi yekuputsika kwekuputika inogona kuderedzwa.
