Iyo instant hydroxypropyl methylcellulose ether yakagadzirirwa zvigadzirwa zvemvura. Iyo yepamusoro yehydroxypropyl methylcellulose ether inobatwa ne glyoxal pasi peimwe tembiricha uye pH kukosha. Iyo hydroxypropyl methyl cellulose ether inobatwa nenzira iyi inongoparadzirwa mumvura isina kwayakarerekera isina kuzvimba uye viscosity, iyo inobata basa mukunonoka kuzvimba. Panguva ino, mhinduro yemvura inokurudzirwa kwemaminitsi mashanu-10 kana iyo Kana iyo mhinduro nharaunda (PH kukosha) inogadziriswa kuti ive alkaline, hydroxypropyl methylcellulose ether inotanga kuzvimba uye kugadzira viscosity. Iyi mhando inorapwa pamusoro inowanzonzi imhando yekukurumidza.
Hunhu hweinstant hydroxypropyl methylcellulose ndeyekuti kana ikasangana nemvura inotonhora, inokurumidza kupararira mumvura inotonhora, asi inotora nguva kuti viscosity yayo isimuke, nekuti inongopararira mumvura mukutanga, uye haina kunyungudika mune pfungwa huru. Viscosity yaro inosvika pakukosha kwepamusoro kwemaminetsi makumi maviri kana kupfuura. Kubatsira kweizvi ndechokuti inoshandiswa mune imwe indasitiri isina kusanganiswa kwehupfu hwakaoma, kana painoda kunyungudutswa uye mvura inopisa haigone kushandiswa nekuda kwemamiriro emidziyo nezvimwe zvikonzero. Instant hydroxypropyl methylcellulose inogadzirisa dambudziko rakadaro.
Instant-type hydroxypropyl methylcellulose inopararira nekukurumidza mumvura (dispersion degree iri 100%), inonyungudika nekukurumidza, haina kudhumhana, kunyanya muchikamu chekupedzisira, iyo colloidal solution ine kujeka kwakanyanya (kusvika 95%) uye kuwirirana kukuru, kunogadzirisa matambudziko. mumashandisirwo anoshanda. Zvipingamupinyi, kuwedzera munda wekushandisa, senge kunyorera mukuvaka glue, iko kushandiswa mumisanganiswa yemvura yakasanganiswa, uye minda yakakosha senge zuva nezuva kugeza makemikari.
Takaunza midziyo yekugadzira uye tekinoroji yepasirose yepamusoro, tine mutsara wemazuva ano wekugadzira cellulose ether uye redispersible latex poda, uye tive nechokwadi chekupa vashandisi zvigadzirwa zvinogutsa nehurongwa hwayo hwekudzora mhando, yekuyedza uye yakakwana pa-saiti sevhisi. Iye zvino zvigadzirwa zvinotungamira ndeye hydroxypropyl methylcellulose HPMC, hydroxyethyl cellulose HEC, hydroxypropyl starch ether HPS, redispersible latex powder series. Zvigadzirwa zvinoshandiswa zvakanyanya mukuvaka, indasitiri yemakemikari, pendi, indasitiri yemakemikari yemazuva ese, indasitiri yemauto nedzimwe minda, uye zvakateerana zvinogadzirwa kuita mafirimu-ekugadzira vamiririri, zvinonamira, zvinoparadzira, stabilizers, thickeners, nezvimwe.
Ichivimba nemhando yechigadzirwa chayo uye chimiro chayo uye pesvedzero muindastiri yehupfu yakaoma yekuvaka zvinhu zvekuwedzera, uye pasi pechikonzero chekugara ichichengetedza chinangwa chekambani chemhando yekutanga, ikozvino yave kushandira pamwe nevagadziri vepasi rese uye vekumba vanozivikanwa vagadziri vezve zvigadzirwa zvinowirirana. Kutsigira mashandiro: polypropylene faibha, Wood fiber, yakagadziridzwa starch ether, polyvinyl doro poda, poda defoamer, mvura inodzikisira, inodzinga mvura, calcium formate uye mamwe akaoma ekuwedzera poda.
