Tikanga mo te whakamahi hydroxypropyl methylcellulose me te tikanga mo te whakarite otinga

Me pehea te whakamahi hydroxypropyl methylcellulose:

Tāpiri tika ki te hanga, ko tenei tikanga te mea ngawari me te wa poto rawa atu, ko nga waahanga e whai ake nei:

1. Tāpirihia he wai kohua (he wairewa nga hua o te hydroxyethyl cellulose ki te wai matao, kia taea e koe te tapiri he wai matao) ki te ipu whakakorikori i te ahotea kutikuti teitei;

2. Tahurihia te mahi whakaoho me te iti-tere, ka ata tatari te hua ki roto i te ipu whakaoho;

3. Me whakaoho tonu kia makuku katoa nga matūriki;

4. Taapirihia he wai matao me te whakaoho tonu kia rewa katoa te hua (kua tino pai ake te maarama o te otinga)

5. Kātahi ka tāpirihia ētahi atu kai ki te tātai

Ko nga mea hei maumahara i te wa e whakareri otinga

(1) Nga hua kaore he maimoatanga mata (haungahydroxyethyl cellulose) kaua e rewa tika ki te wai matao

(2) Me ata tatari ki roto i te ipu whakaranu, kaua e taapirihia te hua nui ki roto i te ipu whakaranu.

(3) Ko te pāmahana me te uara pH o te wai he tino hononga ki te whakakorenga o te hua, na reira me aro nui

(4) I mua i te makuku o te paura hua, kaua e taapiri etahi matū kawakore ki te ranunga, i muri i te makuku o te paura hua ka taea te whakanui ake i te uara ph, ka awhina i te whakakore.

(5) I mua i te taapiri i te kaihoko anti-fungal ka taea

(6) I te wa e whakamahi ana i nga hua-nui, ko te taumaha o te waipiro whaea kaua e neke ake i te 2.5% -3%, mena he uaua te mahi a te waipiro whaea.

(7) Ko nga hua kua tukuna i te maimoatanga tere kaore e whakamahia mo te kai me te rongoa
