Usoro ọrụ nke starch ether na ngwa agha

Starch ether bụ ụdị cellulose ether nke a na-ejikarị eme ihe dị ka ihe mgbakwunye na ngwa agha iji melite arụmọrụ ya. Ọrụ bụ isi nke starch ether na ngwa agha bụ ịkwalite arụmọrụ ya, njigide mmiri, na ihe nrachi. Enwere ike ịkọwa usoro nke starch ether na ngwa agha dị ka ndị a:

1. Nkwalite arụmọrụ: Starch ether nwere ike imeziwanye arụmọrụ nke ngwa agha site na ibelata viscosity nke ngwakọta. A na-enweta nke a site na ntinye nke starch ether molecules n'elu akụkụ simenti, nke na-ebelata ụgwọ eletrik ha ma na-abawanye njem ha. Nke a na-ebelata esemokwu n'etiti ụmụ irighiri ihe, na-enye ha ohere ịkwaga n'efu na ngwa ngwa. N'ihi ya, ngwa agha na-aghọwanye mmiri ma dị mfe iji rụọ ọrụ.
2. Njide mmiri: Starch ether nwere ike imezi njide mmiri nke ngwa agha ahụ site n'ịme ihe nkiri nchebe gburugburu akụkụ ciment. Ihe nkiri a na-egbochi mmiri dị na ngwakọta ka ọ ghara ikpochapụ ngwa ngwa, na-ekwe ka ngwa agha ahụ nọgide na-arụ ọrụ ruo ogologo oge. Nke a dị mkpa karịsịa na ọnọdụ na-ekpo ọkụ ma na-ekpo ọkụ, ebe oke ikuku nke mmiri si na ngwa agha dị elu.
3. Adhesion: Starch ether nwere ike melite nrapado nke ngwa agha na mkpụrụ site na ịba ụba tackiness ya. A na-enweta nke a site na nguzobe nke njikọ hydrogen n'etiti starch ether molecules na elu nke mkpụrụ osisi, nke na-eme ka ike nchikota interfacial dịkwuo elu. Nke a na-eme ka ike njikọ zuru ezu dị n'etiti ngwa agha na mkpụrụ osisi, na-ebelata ohere nke ịwepụ ma ọ bụ ọdịda.

Na nchịkọta, usoro ọrụ nke starch ether na ngwa agha na-adabere n'ikike ya iji kwalite ọrụ, njide mmiri, na nrapado nke ngwakọta. Starch ether na-enweta nke a site n'ibelata viscosity nke ngwakọta, na-eme ihe nkiri nchebe gburugburu akụkụ ciment, na ịbawanye tackiness nke ngwa agha ahụ. Iji starch ether eme ihe na ngwa agha nwere ike imeziwanye arụmọrụ na ịdịte aka nke ngwakọta ahụ, na-eme ka usoro ihe owuwu dị mma ma dị irè.
