HPMC (hydroxyprEpropyl methylcellose) inowanzoitwa polymer yezvinhu inoshandiswa zvakanyanya mukuvaka, mishonga, chikafu, makemikari ezuva nezuva uye mamwe minda. Zvinoenderana nekunyarara kwayo mumvura, inogona kukamurwa kuita mvura inotonhora yemvura inopisa uye inopisa yekupisa mhando. Kune mutsauko wakakosha mukugadzirwa kwemaitiro emhando mbiri idzi dzeHPMC.
(1), kudzima zvinhu zvekugadzirisa
1. Cold mvura Instant Type
Mukugadzirwa kwekugadzira kwemvura inotonhora ipapo HPMC, zvinhu zvakawandisa zvinotanga kufungidzira. Zvishandiso zvakawandisa zvinosanganisira Cellulose, methanol, propyl chloride, methyl chloride, methyl chloride, yakasanganiswa panguva yekunyepedzera kuti ive nechokwadi chekusagadzikana uye kukwana kwekuita. Kunyanya, kurapwa kwe cellulose kunoda kuomesa simba uye kupwanya kuti uwane saizi yakakodzera chikamu chekugoverwa.
2. Hot Melt mhando
Kupisa-Melt HPMC kwakafanana neCold-Water Pink HPMC maererano neRaw zvinyorwa zvekugadzirisa, asi zvine zvinodiwa zvepamusoro zvekugadzirisa cellulose. Nekuti inopisa-melt HPMC inoda kuita kupisa kwakanyanya, kuchena uye kusvitsa kukura kwemheremello kune maitiro akakosha pane maitiro ekuita. Izvo zvinowanzodiwa kuti ushandise yakanyanya-yakanyanya cellity Cellity, uye saizi yemukati inofanira kudzorwa zvakanyatso kudzorwa panguva yekupwanya.
(2), synthesis maitiro
1. Cold mvura Instant Type
Iyo synthesis yakaitwa yemvura inotonhora inowanzoitika HPMC inowanzoitwa pakudziya kwakadzika, inowanzo kudzorwa pamadhora mazana maviri -50 celsius. Munguva yekuita, cellulose inotanga kunyepedzera pasi peAlkaline mamiriro ezvinhu kuHydrolyze iyo cellulose maCellular maketani uye gadzira mahara hydroxyl mapoka. Zvadaro, kuita senge methanol, profylene oxide uye methyl chloride inowedzerwa pasi pemamiriro ekukurudzira kuita shanduko yekuchinja. Iyo yese maitiro maitiro inoda kudzora kudzora kwekushisa uye ph kuti ive nechokwadi chekufanana uye kugadzikana kwechigadzirwa.
2. Hot Melt mhando
Iyo synthesis maitiro ekupisa-melt hpmc inoitwa pakudziya kwakanyanya, kazhinji 50-80 degrees celsius kana kunyange kupfuura. Maitiro ekuita akafanana neyechando mvura inonyura Pakupisa kwakanyanya, iyo hydrolysis uye erfitifitifitifitifiti yeCellulose yakakwana, uye iyo molecular uremu kugoverwa kwechigadzirwa chakanyanya yunifomu.
(3) post-kugadzirisa maitiro
1. Cold mvura Instant Type
Mushure mekuitwa kweSyntesis yemvura inotonhora nekukurumidza HPMC yapedzwa, nhevedzano yekutumira-maitiro maitiro anodiwa. Chekutanga chiitiko chekusarerekera chekusarerekera zvinhu zveAlkaline mumusanganiswa wekuita. Filt uye gages inobva yaitwa kuti ibvise isina kugadzirwa zvisingaiti zvigadzirwa uye ne-zvigadzirwa. Nhanho yekupedzisira iri kuoma uye kudhonzwa. Iyo chigadzirwa chakaomeswa kudzora izvo zvinyoro-nyoro, uye wobva wadururwa kune yakakodzera chidimbu chehukuru hwekuwana iyo yakapera chigadzirwa HPMC.
2. Hot Melt mhando
Iyo post-yekurapa maitiro ekupisa-melt hpmc yakafanana neiyo yeinotonhora-mvura pakarepo hpmc. Nekudaro, nekuda kwekushisa kwakanyanya kunoshandiswa mukuita maitiro, iyo unyoro hwechigadzirwa huri kuderera uye kuomesa maitiro zvakareruka. Mukuwedzera, kupisa-melt HPMC kunoda kutarisisa kutevedzera kupisa kwekupwanya panguva yekupwanya yekudzivirira kuita kwechigadzirwa kwekuita nekuda kwekushisa kwakanyanya.
(4), performance uye application
Mvura inotonhora ipapo HPMC inoshandiswa zvakanyanya muminda inoda kukurumidza kuumbwa kwefirimu kana kuti yakakora, yakadai seyakagadzika matsvuku, etc. Izvo zvigadzirwa zvekugadzira zvido zvakakwirira zvakakwirira, kunyanya kudzora kwemamiriro ezvinhu pakudziya kwekushisa.
Kupisa-Melt HPMC kwakakodzera kune zvinoshandiswa pasi pemamiriro ekunze ekushisa, senge tile inonamira, etty poda, nezvimwe, nekuda kwekunetseka kwayo kwakanyanya mumvura inopisa. Maitiro ayo ekugadzira anoshayiririsa, asi ane zvido zvepamusoro pakucheneswa kwezvinhu zvisina kugadzirwa uye kuita tembiricha tembiricha.
Musiyano mukuru mukugadzira pakati pemvura inotonhora nekukurumidza-mhando Mvura inotonhora inoda kuti iite pakudziya kwakadzika uye kune zvinodiwa pakudziya nePH temport Ivo vaviri vakasiyanawo muminda chaiyo yekushandisa, uye rimwe nerimwe rinoita basa rakakosha.
