HPMC (hydroxypropyl methylcellulose) chinhu chakakosha chedhaka musanganiswa chinoshandiswa zvakanyanya mukuvaka zvinhu. Basa rayo guru rinosanganisira kuvandudza kuchengetwa kwemvura kwedhaka, kuvandudza kushanda uye kuwedzera kuputika kwekudzivirira. Iyo yakatsetseka yeAnxinCel®HPMC ndeimwe yeakakosha parameters ekuita kwayo, iyo inokanganisa zvakananga kunyungudika kwayo uye kugovera mudhaka uye kuvandudza kwayo maitiro ezvivakwa zvedhaka.
1. Tsanangudzo yeHPMC fineness
HPMC kunaka kunowanzo kuratidzwa maererano neavhareji saizi yezvikamu zvayo kana muzana inopfuura nepasefa chaiyo. HPMC zvidimbu zvine high fineness madiki uye ane hombe chaiyo nzvimbo; HPMC zvimedu zvine kunyoroka kwakaderera zvakakura uye zvine diki chaiyo nzvimbo. Fineness ine simba rakakura pachiyero chekuparara, kugovera kufanana uye kupindirana kweHPMC nezvikamu zvesimende.
2. Mhedzisiro pakuchengetedza mvura
Kuchengetwa kwemvura chiratidzo chakakosha chekushanda kwedhaka, iyo inobata zvakananga kushanda kwekuvaka uye hutano mushure mekuoma. Iyo yakakwira kunaka kweHPMC, iyo yakawanda yakagovaniswa zvimedu zviri mudhaka, izvo zvinogona kuumba denser rekuchengetedza mvura chipingamupinyi, nokudaro zvakanyanya kunatsiridza kuchengetwa kwemvura kwedhaka. Uye zvakare, yakanaka-grained HPMC inonyungudika nekukurumidza uye inogona kuchengetedza mvura kare, iyo inonyanya kubatsira mukupisa-kupisa kana kunyura-kunyura kwepasi kwekuvaka.
Nekudaro, kunyanyisa kunaka kunogona kuita kuti HPMC ibatane kana yasvika pakusangana nekukurumidza nemvura, zvichikanganisa kugovera kwayo mudhaka, nekudaro ichideredza iyo chaiyo yekuchengetedza mvura. Naizvozvo, izvo zvinodikanwa zvekushandisa zvinofanirwa kutariswa zvizere kana uchisarudza HPMC kunaka.
3. Kukanganisa kushanda
Kushanda kunoreva kushanda kwekuvaka kwedhaka, iyo inonyanya kuenderana neiyo fluidity uye thixotropy yematope. HPMC zvimedu zvine hunyoro hwepamusoro zvinogona kugadzira yunifomu colloid system mudhaka mushure mekunyungudika, iyo inobatsira kuvandudza kuyerera uye lubricity yedhaka, nekudaro kuvandudza kushanda. Kunyanya mukuvaka kwakagadzirwa, yakakwira-fineness HPMC inogona kuderedza kupfapfaidza kuramba uye kunatsiridza mashandiro ekuvaka.
Pane zvinopesana, nekuda kwekunonoka kupera kwehuwandu hweHPMC zvidimbu zvine hunyoro hwakaderera, dhaka rinogona kunge riine viscosity yakakwana mukutanga nhanho yekusanganisa, inokanganisa mashandiro ekuvaka. Mukuwedzera, HPMC ine zvimedu zvakakura zvinogona kugoverwa zvisina kuenzana mudhaka, zvichikanganisa kushanda kwese.
4. Mhedzisiro pakuramba kwekuputika
Crack resistance inonyanya kukanganiswa nekuomesa shrinkage uye mukati kugovera kufanana kwedhaka. HPMC nehupamhi hwepamusoro inogona kugoverwa zvakaenzana mudhaka kuti iite inoenderera cellulose firimu, iyo inononoka chiyero chekubuda kwemvura uye inoderedza kuoma kwedhaka, nekudaro zvinobudirira kuvandudza kutsemuka kuramba.
Nekune rimwe divi, HPMC ine hunyoro hushoma hunoita kuti igadzire nzvimbo dzakadzika mukati medhaka nekuda kwekusapararira zvakanaka, haikwanise kudzora kuoma kwekuoma, uye ine kushomeka kwekudzivirira.
5. Mhedzisiro pasimba
Iko kunaka kweHPMC kune mhedzisiro isina kunanga pakusimba kwedhaka. HPMC ine hunyoro hwepamusoro kazhinji inobatsira simende kuti iite hydrate zvizere nekuda kwekunatsiridza kuchengetedza kwemvura uye kupararira, nekudaro kuvandudza simba rekutanga redhaka. AnxinCel®HPMC ine fineness yakaderera haina simba mukuparara uye kugovera, izvo zvinogona kutungamira kusakwana kwemvura munzvimbo dzemunharaunda, nekudaro kukanganisa kufanana kwesimba redhaka.
Izvo zvinofanirwa kucherechedzwa kuti yakawandisa HPMC yemukati kana kunaka inogona kuve nemhedzisiro yakaipa pasimba, nekuti cellulose pachayo ine shoma mupiro kune mechanic zvinhu zvedhaka, uye yakawandisa inoderedza reshiyo yeaggregate uye simende.
6. Economic uye kuvaka kufunga
Mumapurojekiti chaiwo, hupamhi hwepamusoro-soro HPMC inowanzo kudhura, asi mabhenefiti ayo ekuita ari pachena, uye inokodzera zviitiko zvine zvakakwirira zvinodikanwa pakuchengetedza mvura uye kuramba kutsemuka. Zvezvido zvekuvaka zvakajairwa, zvine mwero HPMC kutsetseka kunogona kazhinji kuwana chiyero pakati pekuita nehupfumi.
HPMC neyakasiyana fineness ine hunhu hunokosha pane zvinhu zvedhaka. High-fineness HPMC inowanzova nekuita kwepamusoro-soro maererano nekuchengetedza mvura, kushanda uye kusagadzikana kwekuputika, asi mutengo wakakwirira uye unogona kukonzera njodzi yeagglomeration panguva yekuparara; low-fineness HPMC yakaderera mumutengo, asi ine zvisingakwanisi mukuvandudza kwekuita. . Kusarudzwa kunonzwisisika kweAnxinCel®HPMC kunaka maererano nezvinodiwa zvekuvaka izano rakakosha rekugadzirisa kuita kwedhaka uye kudzora mitengo.
