Te pānga matotoru o te cellulose ether

Etera celluloseHe tino matotoru te moata maku, ka taea te whakanui ake i te kaha piri o te moata maku me te moata taketake, te whakapai ake i te mahi ārai-totoka o te moata, e whakamahia whānuitia ana i roto i te moata parai, te pūnaha whakamahana o waho me te moata piri pereki. Ka taea hoki e te pānga matotoru o te cellulose ether te whakanui ake i te ōritetanga me te kaha ārai-marara o ngā rauemi sima hou, hei ārai i te paparanga, te wehewehe me te toto o te moata me te raima, ka taea te whakamahi i roto i te muka raima, te raima raro wai me te raima whakakī-whaiaro.

Etera celluloseKa whakanui ake i te matotoru o ngā rauemi sima mai i te matotoru o te otinga cellulose ether. Ko te tikanga, ka whakamahia te "matotoru" o tēnei inenga hei aromatawai i te matotoru o te otinga cellulose ether, ko te matotoru o te cellulose ether e pā ana ki tētahi kukū (2%) o te otinga cellulose ether, te pāmahana (20 ℃) ​​me te tere kutikuti (te tere hurihuri rānei, pērā i te 20 RPM) tikanga, me ngā whakaritenga o te taputapu ine, pērā i te ine hurihuri i ngā uara matotoru. Ko te matotoru he tawhā nui mō te aromatawai i te mahi a te cellulose ether me te cellulose ether, ko te teitei ake o te matotoru o te otinga, ko te pai ake o te matotoru o te rauemi turanga sima, ko te matotoru o te rauemi turanga ka taea te ātete totoro me te ātete ki te kaha o te marara, engari ki te nui rawa te matotoru, ka pā ki te nekenekehanga me te nekehanga o te rauemi turanga sima (pērā i te hanganga o te moata piri moata). Nō reira, ko te matotoru o te cellulose ether e whakamahia ana i roto i te moata maroke-whakaranu he 15,000 ~ 60,000 Mpa. s-1, ā, me iti ake te matotoru o te cellulose ether mō te moata whakataurite-ake me te raima whakakī-ake me ngā whakaritenga rere teitei ake. Hei tāpiri, ka whakanui ake te pānga matotoru o te cellulose ether i te hiahia wai o ngā rauemi sima, ā, ka whakanui ake i te putanga o te moata. Ko te matotoru o te otinga cellulose ether e whakawhirinaki ana ki te taumaha ngota (te tohu rānei o te polymerization) me te kukū o te cellulose ether, te pāmahana otinga, te tere kutikuti, me te tikanga whakamātautau. Ko te teitei ake o te tohu polymerization o te cellulose ether, ko te nui ake o te taumaha ngota, ko te teitei ake o te matotoru o tōna otinga wai; Ko te teitei ake o te horopeta (te kukū rānei) o te cellulose ether, ko te teitei ake o te matotoru o tōna otinga wai, engari i te whakamahinga me aro ki te whiriwhiri i te horopeta tika, kia kore ai e tino nui te ranunga, ka pā ki te mahi o te moata me te raima; Pērā i te nuinga o ngā wai, ka heke te matotoru o te otinga cellulose ether me te pikinga o te pāmahana, ā, ko te teitei ake o te kukū o te cellulose ether, ko te nui ake o te pānga o te pāmahana; Ko te otinga cellulose ether he tinana pseudoplastic me te āhuatanga o te angiangi kutikuti. Ka iti ake te matotoru ka nui ake te tere kutikuti.

Nō reira, ka whakaitihia te piri o te moata e te kaha o waho, ā, ka āwhina tēnei ki te hanga waru o te moata, ka pai ai te mahi me te piri o te moata. Heoi, ka whakaatu te otinga cellulose ether i ngā āhuatanga wai Newtonian ina tino iti te kukū, ā, he iti rawa te matotoru. Ina piki te kukū, ka āta whakaatu te otinga i ngā āhuatanga wai rūpahu, ā, ki te teitei ake te kukū, ka kitea te rūpahu.
