1. HPMC yakakamurwa kuva mhando yekukurumidza uye mhando yekukurumidza kuparadzira.
Rudzi rweHPMC runonzi rapid dispersion type rune bhii S se suffix. Glyoxal inofanira kuwedzerwa panguva yekugadzira.
Rudzi rweHPMC runopararira nekukurumidza haruwedzere mabhii, akadai sekuti “100000″ zvinoreva kuti “100000 viscosity inopararira nekukurumidza HPMC”.
2. Kana paine kana pasina S, hunhu hwacho hwakasiyana
HPMC inopararira nekukurumidza inopararira nekukurumidza mumvura inotonhora yonyangarika mumvura. Mvura iyi haina viscosity panguva ino nekuti HPMC inongopararira mumvura chete uye hainyungudike chaizvo. Mushure memaminitsi maviri, viscosity yemvura inowedzera zvishoma nezvishoma, zvichiita mvura yakajeka ine viscosity. Colloid gobvu.
HPMC inokurumidza inogona kuparadzirwa nekukurumidza mumvura inopisa panosvika 70°C. Kana tembiricha yadzikira kusvika patembiricha yakati, viscosity inooneka zvishoma nezvishoma kusvika yaumbwa colloid yakajeka ine viscous.
3. Chinangwa chakasiyana neS kana kuti kwete
HPMC Instant inogona kushandiswa chete muupfu hweputty nemortar. Mumaglue emvura, pendi nezvinhu zvekuchenesa, mabundu anogona kuitika uye haachashandiswi.
HPMC inopararira nekukurumidza ine mashandisirwo akasiyana-siyana. Inogona kushandiswa pakugadzira putty powder, mortar, liquid glue, pendi, uye zvinhu zvekuchenesa pasina chero chipingamupinyi.
nzira yekunyungudutsa
1. Tora huwandu hunodiwa hwemvura inopisa, uiise mumudziyo woipisa kusvika pamusoro pe80℃, wobva wawedzera chigadzirwa ichi zvishoma nezvishoma uchikurunga zvishoma nezvishoma. Cellulose inoyangarara pamusoro pemvura pakutanga, asi inopararira zvishoma nezvishoma kuti iite slurry yakafanana. Tonhodza mushonga uchikurunga.
2. Kana kupisa 1/3 kana 2/3 yemvura inopisa kusvika pamusoro pe85°C, wedzera cellulose kuti uwane slurry yemvura inopisa, wobva wawedzera mvura inotonhora yasara, kurunga nguva dzose, wotonhodza musanganiswa wabuda.
3. Cellulose ine saizi yakatsetseka uye inowanikwa sezvidimbu zvidiki zvidiki muupfu hwakasanganiswa. Inonyungudika nekukurumidza kana yaiswa mumvura kuti igadzire viscosity inodiwa.
4. Wedzera cellulose zvishoma nezvishoma uye zvakaenzana patembiricha yemumba, uchikurunga nguva dzose kusvika mhinduro yakajeka yagadzirwa.
Ndezvipi zvinhu zvinokanganisa kuchengetwa kwemvura kwehydroxypropyl methylcellulose?
Kuchengetwa kwemvura kwezvigadzirwa zve hydroxypropyl methylcellulose HPMC pachako kunowanzo kanganiswa nezvinhu zvinotevera:
1. Kufanana kwe cellulose ether HPMC
Mapoka eHPMC methoxy nehydroxypropoxy ane mhinduro dzakafanana akapararira zvakaenzana uye ane mvura yakawanda inochengetwa.
2. Kupisa kwegel yekupisa yeCellulose ether HPMC
Kana tembiricha yegel inofambisa mvura yakakwira, chiyero chekuchengetedza mvura chakakwira; asi, chiyero chekuchengetedza mvura chakaderera.
3. Kupenya kwe cellulose ether HPMC
Kana viscosity yeHPMC ikawedzera, mwero wekuchengetedza mvura unowedzerawo; kana viscosity yasvika padanho rakati, kuwedzera kwemwero wekuchengetedza mvura kunowanzova kushoma.
Kuwedzera kwehuwandu hwekuwedzera kweCellulose ether HPMC
Kana huwandu hwe cellulose ether HPMC hwakawedzerwa hwakawanda, mwero wekuchengetedza mvura unowedzera uye mhedzisiro yekuchengetedza mvura iri nani.
Muchikamu che0.25-0.6%, mwero wekuchengetedza mvura unowedzera nekukurumidza sezvo huwandu hwekuwedzera huchiwedzera; kana huwandu hwekuwedzera huchiwedzera, mwero wekuwedzera kwehuwandu hwekuchengetedza mvura unoderera.
