Me kōrero tātou mō te hydroxypropyl methyl celluloseHPMCme pēhea te ine i tōna matotoru. Ko te matotoru i konei e pā ana ki te matotoru āhua, he tohutoro nui tēnei ki te hydroxypropyl methyl cellulose.
Paerewa. Ko ngā tikanga ine noa ko te ine matotoru hurihuri, te ine matotoru capillary me te ine matotoru heke. Ko te tikanga whakatau o te hydroxypropyl methyl cellulose ko te piri capillary.
Ko te tikanga whakatau i te nekehanga, mā te whakamahi i te mita wai Uchs. Ko te tikanga ko te whakatau i te otinga he 2% te wai, ko te tātai ko: V=Kdt. Ko V te matotoru i roto i te mpa. s, ā, ko K te pūmau mita wai.
Ko D te mātotoru i te pāmahana pumau, ā, ko T te wā mai i runga ki raro i roto i te ine matotoru i roto i ngā hēkona. He uaua ake tēnei tikanga mahi, mēnā he mea kore e rewa.
He ngāwari te hapa i ngā kupu, he uaua ki te tautuhi i te kounga o te hydroxypropyl methyl cellulose. Ināianei kua whakamahia whānuitia hei ine i te matotoru o te mita hurihuri, te whakamahinga whānui i Haina.
Ko te tātai o te mita waikeri NDJ-1 ko η=Kα. Ko η te matotoru, kei roto hoki i te mpa.s, ko K te tauwehenga o te mita waikeri, ā, ko α te pānui o te tohu mita waikeri.
Tikanga whakamātautau matotoru 2% Hydroxypropyl methyl cellulose:
1, he pai tēnei tikanga mō te whakatau i te matotoru hihiri o ngā wai ehara i te Newtonian (he otinga polymer, he whakatārewatanga, he wai marara emulsion, he otinga surfactant rānei, me ētahi atu).
2. Ngā taputapu me ngā taputapu
2.1 Ine ā-hurihuri (e hiahiatia ana te NdJ-1 me te NDJ-4 e te Pūtaiao Rongoā Hainamana)
2.2 Te pāmahana pumau o te kaukau wai, te tika o te pāmahana pumau 0.10C
2.3 Ko te taumata whakatau pāmahana he 0.20C, ā, ka manatokohia i ia wā.
2.4 Me rāhui ngā mita auau me ngā mita viscometer e whakamahi ana i ngā inenga pumau auau (pēnei i te NDJ-1 me te NDJ-4). Ko te tika o te 1%. A.
8. I paunatia tika te tauira 0g, ā, i whakanohoia ki roto i tētahi kapu maroke, kua whakatōkia, he 400mL te teitei. Tāpirihia kia 100mL te wai wera 80-90 nekehanga, ka whakaohokia mō te 10 meneti kia wehea.
Horahia kia ōrite, whakaohokia, ka tāpirihia he wai matao ki te 400mL katoa. I taua wā, whakaohokia tonutia mō te 30 meneti kia puta he otinga 2% (W/W), ka maka ki roto i te pouaka whakamātao kia whakamatao kia hanga he hukapapa angiangi ki runga i te mata.
Tangohia, ka maka ki roto i te ipu pāmahana pumau kia mau tonu te pāmahana pokapū ki te 20 ℃ 0.1 ℃.
3.1 Me whakahaere te tāutanga me te whakahaere i te taputapu i runga anō i ngā tohutohu whakahaere o te taputapu, ā, me whiriwhiri te rotor me te rotor e tika ana i runga anō i te whānuitanga matotoru o te hua kua whakamatautauria me ngā whakaritenga o te rongoā i raro i te tuhinga o te hua.
Te tere hurihuri.
3.2 Whakatikatikahia te pāmahana pumau o te wai kia rite ki te whakatau i raro i ia tūemi rongoā.
3.3 I whakatakotoria te hua whakamātautau ki roto i te ipu i tohua e te taputapu, ā, i inehia te Koki piko (a) i runga i te ture i muri i te 30 meneti o te pāmahana pumau. Whakawetohia te motuka ka tīmata anō kia whakatauhia anō.
Kaua te rerekētanga i waenga i ngā uara toharite e neke ake i te 3%, ki te kore me mahi i tētahi ine tuatoru.
3.4 Tātaihia te uara toharite o ngā whakamātautau e rua e ai ki te tātai hei whiwhi i te matotoru hihiri o te hua i whakamatautauria.
4. Tuhia me te tatau
4.1 Tuhia te tauira o te mita hurihuri, te tau me te tere o te rotor i whakamahia, te pūmau mita (uara K '), te pāmahana i inehia, me ia uara inenga.
Te tātai tatau o te 4.2
Matotoru hihiri (MPa”s)=Ka ko K te pūmau viscometer i inehia ki te wai paerewa e mōhiotia ana te matotoru, ā, ko A te Koki whakapēhanga
