Iindlela eziqhelekileyo nezilula zokwahlula umgangatho we-HPMC cellulose

Iindlela eziqhelekileyo nezilula zokwahlula umgangatho we-HPMC cellulose:

1. Ubume obubonakalayo be-HPMC ecocekileyo ye-cellulose i-fluffy, kwaye i-bulk density incinci, kunye noluhlu lwe-0.3-0.4g / ml; Iselulosi ye-HPMC egqwethiweyo inobumanzi obungcono kunye nokuziva kwesandla esinzima, okwahluke kakhulu kwinkangeleko yeemveliso zokwenyani.

2. Ubumhlophe be-HPMC cellulose ecocekileyo ilungile, nto leyo ethetha ukuba izinto ezisetyenziswayo kwimveliso zinyulu kwaye ukusabela kucokisekileyo ngaphandle kokungcola. Xa kuthelekiswa neemveliso ze-ether ze-cellulose zangaphandle ezifanelekileyo, kunokubonwa ukuba ubumhlophe bemveliso ye-ether ye-cellulose efanelekileyo buhlala bungcono kunemveliso yasekhaya yomgca wesibini.

3. I-HPMC ecocekileyo ye-cellulose isisombululo se-aqueous icacile, kunye nokuhanjiswa kokukhanya okuphezulu, kunye nesantya sokugcinwa kwamanzi ≥ 97%; Isisombululo esinamanzi seselulosi ye-HPMC sigxunyekwe, kwaye izinga lokugcinwa kwamanzi kunzima ukuhlangabezana neemfuno. Ukuhanjiswa kokukhanya kwesisombululo se-aqueous kulungile, esibonisa ukuba imveliso iqulethe izinto ezincinci ezingenayo kunye nomxholo ophezulu wezithako ezisebenzayo.

4. Iselulosi ye-HPMC ecocekileyo ayifanele ivumba i-ammonia, isitashi kunye notywala; Iselulosi yeHPMC egqwethiweyo inokujoja zonke iintlobo zencasa. Nokuba ayinancasa, iya kuva ubunzima.

5. I-HPMC ecocekileyo ye-cellulose powder i-fibrous phantsi kwe-microscope okanye iglasi yokukhulisa; Iselulosi ye-HPMC egqwethiweyo inokubonwa njengento eqinileyo yegranular okanye ikristale phantsi kwemakroskopu okanye iglasi yokukhulisa.

6. Indlela elula yokuvavanya isiqulatho sothuthu lwe-etere ye-cellulose: ubunzima obunye ukuya kwiigram ezimbini ze-ether yeselulosi, yivutha nge-lighter, ulinganise intsalela yothuthu eshiywe kukutsha kwe-ether cellulose, kwaye xa intsalela yothuthu / i-ether cellulose ≥ 5 %, umgangatho we-cellulose ether ngokusisiseko awufaneleki. (kukho iimpazamo ngamanye amaxesha kule ndlela. Okokuqala, umenzi wadibanisa iimveliso ezilungele abathengi abathile kubathengi ngaphambi kokushiya umzi-mveliso; okwesibini, ii-arhente okanye abavelisi bongeza izinto ezinokutsha ezinothuthu oluphantsi xa zikrexeza)

7. Ezinye iifektri kunye namakhaya zisebenzisa inani elincinci le-C cellulose elixutywe kwi-hydroxypropyl methyl cellulose ether, kwaye xa isisombululo se-aqueous se-C cellulose sidibana ne-tin, isilivere, i-aluminium, i-lead, isinyithi, ubhedu kunye nezinye izinyithi ezinzima, ukusabela kwemvula kuya kwenzeka; Xa i-c-cellulose isisombululo se-aqueous sihlala kunye ne-calcium, i-magnesium kunye netyuwa, ayiyi kuvelisa imvula, kodwa iya kunciphisa i-viscosity ye-c-cellulose isisombululo samanzi.

8. Ukuba iimeko zivuma, vavanya ngokuthe ngqo i-viscosity yesisombululo esinamanzi se-cellulose ether kwaye uthelekise izinga lokugcinwa kwamanzi kumxholo ophantsi we-cellulose ether mortar.

Njengomvelisi we-cellulose ether oyingcali, uYoungcel cellulose iya kubonelela abathengi ngeemveliso ezikumgangatho ophezulu kunye neenkonzo ngentliziyo iphela
