Kuvandudza mhedzisiro yeHPMC dhaka pane kongiri

Mumakore achangopfuura, nekuenderera mberi kwekuvandudzwa kwekunze kwemadziro ekudzivirira tekinoroji, kuenderera mberi kwehunyanzvi hwekugadzira cellulose, uye hunhu hwakanakisa hweHP cellulose pachayo, HP cellulose yakashandiswa zvakanyanya muindasitiri yekuvaka. Kuti tinzwisise zvakadzama magadzirirwo eHP cellulose uye simende-yakavakirwa zvinhu, bepa rino rinounza kuvandudzwa kweHP cellulose pakubatanidzwa kwesimende-yakavakirwa zvinhu.

kuisa nguva：

Nguva yekumisikidza kongiri inonyanya kuenderana nenguva yekumisikidza simende, uye iyo yakaunganidzwa haina mhedzisiro, saka nguva yekumisikidza yedhaka inogona kushandiswa pachinzvimbo chekudzidza mhedzisiro yeHP cellulose panguva yekumisikidza yepasi pemvura isiri inorasika kongiri musanganiswa. Sezvo nguva yekugadzika yedhaka inobatwa nemvura simenti reshiyo uye simende jecha reshiyo, kuti uongorore mhedzisiro yeHP cellulose panguva yekugadzika kwedhaka, zvinodikanwa kugadzirisa mvura simende ratio uye simende jecha reshiyo yedhaka.

Mhedzisiro yekuedza inoratidza kuti kuwedzera kweHP cellulose kune pachena kudzoreredza musanganiswa wedhaka, uye nguva yekumisikidza yedhaka inowedzerwa nekuwedzera kweHP cellulose yemukati. Pasi peiyo hp cellulose yemukati, nguva yekugadzika yedhaka yakaumbwa pasi pemvura yakareba kupfuura iyo yakaumbwa mumhepo. Kana yakayerwa mumvura, nguva yekugadzika yedhaka yakasanganiswa neHP cellulose ndeye 6 ~ 18 h inononoka mukugadzirisa kwekutanga uye 6 ~ 22 h inononoka mukugadzirisa kwekupedzisira kana ichienzaniswa nemuenzaniso usina chinhu. Naizvozvo, HP cellulose inofanirwa kusanganiswa neyekutanga simba mumiriri.

HP cellulose ndeye yakakwira molecular polymer ine macromolecular linear chimiro uye hydroxyl mapoka pamapoka anoshanda, ayo anogona kugadzira hydrogen zvisungo nemamorekuru emvura anosanganisa kuwedzera viscosity yemvura inosanganiswa. Iyo yakareba mashetani echeni eHP cellulose inokwezva mumwe nemumwe, ichiita HP cellulose mamorekuru anopindirana kuti agadzire network chimiro, inoputira simende nekusanganisa mvura. Nekuda kweiyo network chimiro chakafanana nefirimu yakaumbwa neHP cellulose uye kuputira kwayo simende, inogona kudzivirira zvinobudirira kubuda kwemvura mudhaka uye kutadzisa kana kunonoka hydration kumhanya simende.
