Ebe ọ bụ na HEMC nwere ezigbo ihe nkiri na-emepụta ihe nkiri, ọ nwere ike ịmepụta ihe nkiri otu n'elu ihe owuwu ahụ, si otú ahụ na-eme ka adhesion dị n'etiti ihe na mkpụrụ. Ngwongwo a dị mkpa karịsịa na ngwa dị ka adhesives tile na putties, ebe ọ nwere ike imeziwanye ogologo oge na nkwụsi ike.
Melite nguzogide oyi-ịza
N'ebe oyi na-atụ siri ike, nguzogide ihe na-ajụ oyi dị mkpa karịsịa. HEMC na-eme ka ihu igwe na-eguzogide ihe onwunwe site n'ịkwalite nkesa mmiri dị n'ime ihe ahụ na ibelata mgbanwe olu nke oyi na-agbaze nke mmiri na-eme n'oge oyi na-agbaze.
4. Ụdị ikpe na ngwa bara uru
ngwa agha akọrọ
Na ngwa ngwa akọrọ, HEMC ọ bụghị nanị na-eme ka njide mmiri na ịrụ ọrụ nke ngwa agha ahụ dịkwuo mma, kamakwa ọ na-eme ka ọrụ nke ihe na-arụ ọrụ dịkwuo mma, na-eme ka ngwa ngwa dị mfe ịgbasa na ịkpụzi n'oge usoro ihe owuwu.
Gluu tile
HEMC nwere ike imeziwanye ike njikọ nke colloid na nrapado tile seramiiki, hụ na njikọ siri ike n'etiti taịlị seramiiki na ihe ndị dị n'ime ala, ma belata mwepu ihe mgbe a na-ewu ya.
Putty ntụ ntụ
N'ime ntụ ntụ putty, HEMC nwere ike imeziwanye ịdị mma n'elu, mee ka mmiri na-eguzogide mmiri na mgbawa nke mkpuchi, ma mee ka oyi akwa putty rụọ ọrụ nke ọma na-arụ ọrụ na-esote (dị ka agba latex).
Hydroxyethyl methylcellulose abụrụla ihe mgbakwunye dị mkpa na ihe dị mkpa n'ime ihe owuwu ọgbara ọhụrụ n'ihi njiri mara mma ya, njigide mmiri, mmanu na ihe ndị ọzọ. Ọ bụghị naanị na ọ na-eme ka usoro nhazi nke ihe dị mma dịkwuo mma, kamakwa ọ na-eme ka arụmọrụ na ịdịte aka nke ngwaahịa emechara, na-eweta nnukwu mma na uru na ndị ọrụ na-ewu ụlọ na ndị ọrụ. Site na ọganihu teknụzụ na-aga n'ihu, a ga-agbasawanye mpaghara ngwa na mmetụta nke HEMC, na-enyekwu aka na mmepe nke ụlọ ọrụ mmepụta ihe.
