Te Pūtauora Waikawa (HEC)He etera cellulose kore-ionic te mea e whakamahia whānuitia ana i roto i ngā pūnaha peita wai. Hei whakamātotoru nui, hei kaihoko pupuri wai, hei kaihoko whakatārewatanga hoki, he mea nui te mahi a te HEC i roto i te hanga me te tono peita rapa. Ka pā tika ngā āhuatanga matotoru o te HEC ki te mahi hanga, te mahi paninga me te kounga kiriata peita o te peita rapa.
1. Ngā mahi taketake o te hydroxyethyl cellulose
Ko ngā mahi a HEC i roto i te peita rapa e whai ake nei:
Pānga whakamātotoru: Mā te whakanui ake i te matotoru o te pūnaha o te peita rapa, ka whakarei ake i te rheology o te peita, ka māmā ake te whakahaere i te wā hanga.
Ārai-heke: Whakanuia te kaha thixotropy o te peita hei ārai i te hinga me te heke.
Te whakapai ake i te hanganga: Whakapai ake i te maeneene o te paraihe, te hurihuri, te rehu rānei.
Te whakapai ake i te pumau: Whakapai ake i te whakatarewatanga o ngā tae me ngā whakakī hei ārai i te whakatōputanga me te paparanga.
Te whakaroa i te maroke: Ka āwhina ki te whakapai ake i te hanganga kiriata, te mātotoru me te papatahi o te kiriata peita.
2. Te whakarōpūtanga o te HEC me ngā matotoru rerekē
E toru ngā wāhanga o te HEC, e ai ki te matotoru o tōna wairewa wai i tētahi kukū motuhake: te matotoru iti, te matotoru waenga me te matotoru teitei. Ko te tikanga ka wehewehea mā te matotoru o tētahi wairewa wai 2% (mPa·s):
He iti te matotoru o te HEC: 100-5,000 mPa·s
He matotoru waenga HEC: 5,000-30,000 mPa·s
HEC matotoru teitei: 30,000-100,000 mPa·s, neke atu rānei
3. Te whakataurite i ngā pānga tono o te HEC me ngā matotoru rerekē i roto i te peita rapa
3.1. Ngā āhuatanga tono o te HEC matotoru iti
Ngā Painga: he pai te horapa, he tere te whakarewa, ā, he mārama te pūnaha.
Ngā horopaki e tika ana: He pai mō ngā taiao hangahanga e hiahia ana kia iti te matotoru me te whakataurite pai, pērā i te peita rapa rehu.
Ngā Here: Ka ngoikore te kaha ki te whakamātotoru, ka piko pea i te wā e hangaia ana, ā, he iti noa te āwhina ki te aukati i te ua.
3.2. Ngā āhuatanga tono o te HEC matotoru waenga
Ngā Painga: Mā te whakaaro ki te matotoru me te rere, ka taea te hanga i te thixotropy taurite, ā, ka taea te whakatutuki i ngā hiahia o ngā momo tikanga hanga.
Ngā āhuatanga e tika ana: He whānuitia te whakamahinga i roto i te peita rapa pakitara noa, he pai mō te paraihe me te hurihuri.
Mahi: Ka taea te whakahaere pai i te whakahekenga, me te whakarite kia papatahi, kia ōrite hoki te kiriata peita.
3.3. Ngā āhuatanga tono o te HEC matotoru teitei
Ngā Painga: He kaha whakamātotoru pai, he pai te mahi ārai-totoka mō te peita, ā, he pumau hoki mō te whakatārewatanga.
Ngā āhuatanga e tika ana: He pai mō te peita matotoru, te peita rapa pakitara o waho, ngā huihuinga rānei e hiahiatia ana he nui mō te ārai-totoka.
Kia mōhio: He roa te wā memeha o te HEC matotoru teitei, ā, he ngāwari ki te hanga i ngā puranga. Me aro nui ki te whakahaere i te tere o te horapa me te horapa; i te wa ano, ka pā te matotoru teitei ki te whakataurite i te hanganga.
4. Ngā tūtohutanga kōwhiringa me te arotautanga tātai
I te hoahoa i te tauira peita rapa, me whai whakaaro te kōwhiringa matotoru o te HEC ki ngā āhuatanga e whai ake nei:
Tikanga hanga: Ka whakatairangahia e te rehu ngā hua matotoru iti, ā, ka taea te whakamahi i te matotoru reo me te matotoru teitei mā te paraihe me te hurihuri.
Momo peita: Ka taea te whakamahi i te matotoru waenga mō te peita pakitara o roto; me whiriwhiri te matotoru teitei mō te peita pakitara o waho me te peita matotoru.
Te pumau o te rokiroki: He pai ake te whai huatanga o te HEC matotoru teitei ki te aukati i te taunga me te wehewehe.
Taiao āhuarangi: I roto i te taiao maroke, ka taea e te HEC matotoru teitei te pupuri i te wai.
Ka taea te whakatutuki i te taurite mahi mā te whakakotahi i ngā HEC o ngā matotoru rerekē. Hei tauira, ka tāpirihia he wāhanga iti o te matotoru iti me te wāhanga nui o ngā hua matotoru reo ki te peita rapa hei whakapai ake i te hanganga me te thixotropy.
Ngā pānga o te tonote hydroxyethyl cellulose o ngā matotoru rerekē i roto i te mamae rapakāore he arotahi rerekē. Mā te whiriwhiri tika me te whakatakotoranga pūtaiao e kore e taea te whakapai ake i te mahi a te peita anake, engari ka arotau hoki i te wheako kaiwhakamahi me te utu hua. Me whakakotahi e ngā kaihanga peita ngā āhuatanga tono motuhake me te tono mākete, me te whiriwhiri tika kia nui ake ai te whai huatanga o te HEC.
