Ngwa nke Starch Ether na ngwaahịa ndị dabeere na ciment

Starch ether bụ ụdị Hydroxypropyl starch ether nke a na-ejikarị dị ka ihe mgbakwunye na ngwaahịa ndị sitere na ciment dị ka ngwa agha, konkịtị, na grouts.Ọrụ bụ isi nke starch ether na ngwaahịa ndị a bụ imeziwanye ọrụ ha, njide mmiri, na njigide.Enwere ike ịkọwa ngwa nke starch ether na ngwaahịa simenti dị ka ndị a:

1. Nkwalite arụ ọrụ: Starch ether nwere ike melite arụmọrụ nke ngwaahịa ndị sitere na ciment site na ibelata viscosity ha.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-enye ohere ka akụkụ ciment ahụ na-agagharị n'efu, na-eme ka mmiri dịkwuo mfe ma dị mfe ịrụ ọrụ na ngwakọta.
2. Njide mmiri: Starch ether nwere ike melite njide mmiri nke ngwaahịa simenti sitere na ịmepụta ihe nkiri nchebe gburugburu akụkụ ciment.Ihe nkiri a na-egbochi mmiri dị na ngwakọta ahụ ka ọ ghara ikpochapụ ngwa ngwa, na-ekwe ka ngwaahịa ciment na-arụ ọrụ ruo ogologo oge.Nke a dị mkpa karịsịa na ọnọdụ na-ekpo ọkụ ma na-ekpo ọkụ, ebe ọnụọgụ mmiri nke mmiri si na ciment dabeere na ngwaahịa dị elu.
3. Adhesion: Starch ether nwere ike imeziwanye nrapado nke ngwaahịa simenti na mkpụrụ site n'ịbawanye tackiness ha.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 oke dị n'etiti ngwaahịa simenti na mkpụrụ, na-ebelata ihe ize ndụ nke nkwụsị ma ọ bụ ọdịda.
4. Nguzogide mgbawa: Starch ether nwekwara ike imeziwanye mgbape mgbape nke ngwaahịa ndị sitere na ciment site n'ịkwalite ike nkwụsị ha.A na-enweta nke a site n'ịmepụta netwọk akụkụ atọ nke starch ether molecules na ngwakọta, nke na-arụ ọrụ dị ka ihe nkwado ma na-enyere aka kesaa nrụgide tensile karịa.Nke a nwere ike imeziwanye ogologo oge na ogologo oge nke ngwaahịa sitere na ciment.

Na nchịkọta, ntinye nke starch ether na ngwaahịa ndị dabeere na ciment nwere ike ime ka ọrụ ha dịkwuo mma, njide mmiri, adhesion, na mgbawa na-eguzogide.Starch ether na-enweta nke a site n'ibelata viscosity nke ngwakọta, na-eme ihe nkiri nchebe gburugburu akụkụ ciment, na-abawanye tackiness nke ngwakọta, na ịkwalite ike ike nke ngwaahịa ahụ.Iji starch ether eme ihe na ngwaahịa ndị dabeere na ciment nwere ike imeziwanye arụmọrụ na ịdịte aka nke ngwakọta ahụ, na-eme ka usoro ihe owuwu dị mma ma dị irè.
