Te karaehe peita HEC
Te taumata peitaKo te HEC Hydroxyethyl cellulose he momo pūmua wai-wai kore-ionic, he paura mā, he paura kōwhai rānei, he ngāwari ki te rere, kāore he kakara, kāore he reka, ka taea te wairewa i roto i te wai matao me te wai wera, ā, ka piki ake te tere wairewa i te pāmahana, kāore e wairewa i te nuinga o ngā whakarewa waro. He pai te pumau o te PH me te iti o te huringa matotoru i roto i te awhe ph2-12. He nui te ātete o te HEC ki te tote me te kaha hygroscopic, ā, he kaha te pupuri wai hydrophilic. He kaha te mahi o te mata o tana otinga wai, ā, he teitei te pseudoplasticity o ngā hua matotoru. Ka taea te hanga hei kiriata mārama kore-wai me te kaha ngawari, kāore e poke ngāwari i te hinu, kāore e pāngia e te mārama, kei a ia tonu te kiriata wai-wai HEC. I muri i te maimoatanga mata, ka marara te HEC, kāore e hono ki te wai, engari ka rewa pōturi. Ka taea te whakarite i te PH ki te 8-10, ā, ka tere te rewa.
Ngā āhuatanga matua
Hte hidroksietiri o te pūtau(HEC)Ko te take he taea te rewa ki te wai matao me te wai wera, ā, kāore he āhuatanga tiēre. He whānuitia te whānuitanga o te whakakapinga, te wairewatanga me te matotoru. He pai te pumau o te wera (i raro i te 140°C) ā, kāore e puta he ua i raro i ngā āhuatanga waikawa. Ka taea e te otinga hydroxyethyl cellulose (HEC) te hanga i tētahi kiriata mārama, he āhuatanga kore-ionic kāore e taunekeneke ki ngā ion, ā, he pai te hototahitanga.
Hei korori tiaki, ka taea te whakamahi i te HEC karaehe peita mō te whakapūhuitanga emulsion vinyl acetate hei whakapai ake i te pumau o te pūnaha whakapūhuitanga i roto i te whānuitanga PH whānui. I roto i te hanga hua kua oti te hanga i te tae, te whakakī me ētahi atu tāpiringa kia taurite te horapa, kia pumau, kia whakarato hoki i te pānga matotoru. Ka taea hoki te whakamahi mō te styrene, te kiriaku, te kiriaku me ētahi atu pūhui whakatārewatia hei whakamarara, ā, ka whakamahia i roto i te peita rapa ka taea te whakapai ake i te matotoru, te whakapai ake i te mahi whakataurite.

Te tikanga tono o te hydroxyethyl cellulose HEC i roto i te waipeita
1. Tāpirihia tika ina huri ana i te tae: ko tēnei tikanga te mea māmā rawa, ā, he poto te wā e pau ana. Ko ngā mahi taipitopito e whai ake nei:
(1) Tāpirihia te wai parakore e tika ana ki roto i te VAT o te mīhini tapahi teitei (ko te tikanga, ka tāpirihia te ethylene glycol, te kaihoko whakamakuku me te kaihoko hanga kiriata i tēnei wā)
(2) Tīmatahia te whakaoho i te tere puhoi, ā, tāpirihia mārire te hydroxyethyl cellulose
(3) Me whakaoho tonu kia mākū katoa ngā matūriki
(4) tāpirihia he aukati harore, he kaiwhakahaere PH, me ētahi atu
(5) Whakaohokia kia memeha rawa te hydroxyethyl cellulose (ka tino piki ake te matotoru o te wairewa) i mua i te tāpiri i ētahi atu wāhanga ki te tauira, ā, hurihia kia huri hei peita.
2. te whakarite i te wai whaea e tatari ana: ka whakaritea tuatahitia tēnei tikanga ki te wai whaea kukū teitei ake, kātahi ka tāpirihia te peita rapa, ko te painga o tēnei tikanga he ngāwari ake, ka taea te tāpiri tika ki ngā hua peita kua oti, engari me tika te rokiroki. He rite ngā mahi me ngā tikanga ki ngā mahi (1) – (4) i roto i te Tikanga 1, engari kāore e hiahiatia he kaiwhakaoho tapahi teitei, ā, ko ētahi kaiwhakaoho anake he kaha hei pupuri i ngā muka hydroxyethyl kia marara noa i roto i te otinga he rawaka. Me whakaoho tonu kia memeha katoa ki roto i te otinga matotoru. Kia mahara me tāpiri wawe te aukati harore ki te wai whaea.
3. Te āhua o te pāreti: Nā te mea he kino ngā whakarewa waro mō te hydroxyethyl cellulose, ka taea te tāpiri i ēnei whakarewa waro ki te pāreti. Ko ngā whakarewa waro e whakamahia whānuitia ana pērā i te ethylene glycol, te propylene glycol, me ngā kaihanga kiriata (pērā i te hexadecanol, te diethylene glycol butyl acetate rānei), he ngoikore hoki te wai hukapapa, nō reira he maha ngā wā ka whakamahia te wai hukapapa me ngā wai waro i roto i te pāreti. Ka taea te tāpiri tika i te hydroxyethyl cellulose pērā i te paraoa ki te peita. Kua whakakīia te Hydroxyethyl cellulose ki te āhua o te pāreti. Whai muri i te tāpiri i te lacquer, whakarewa tonu, ā, ka whai pānga matotoru. Whai muri i te tāpiri, me whakaoho tonu kia memeha rawa te hydroxyethyl cellulose, kia ōrite hoki. Ka hangaia he pāreti noa mā te whakaranu i ngā wāhanga e ono o te whakarewa waro, te wai hukapapa rānei me te wāhanga kotahi o te hydroxyethyl cellulose. Whai muri i te 5-30 meneti pea, ka kitea te kounga o te peita.HECka waiora, ka kitea te pikinga. I te raumati, he nui rawa te haumākū o te wai, kāore e taea te whakamahi mō te parāoa.
4. Ngā take hei aro atu ina whakauruhia te waikura whaea hydroxyethyl cellulose:
Pngā whakatūpato
1 I mua me muri i te tāpiri i te karaehe peitaHEC, me whakaoho tonu kia tino mārama, kia mārama hoki te wai.
2. Tātarihia mārire te hydroxyethyl cellulose ki roto i te tāke whakaranu. Kaua e tāpirihia ki roto i te tāke whakaranu i roto i te nui, kaua hoki e tāpiri tika ki roto i te peita papatipu, porowhita rānei.HEC.
3. He mārama te hononga o te pāmahana wai me te uara pH o te wai ki te whakarewanga o te taumata peita.HECte hydroxyethyl cellulose, nō reira me aro nui ki tēnei.
Kaua e tāpirihia tētahi matū taketake ki te ranunga i mua i te taumata o te peita.HECKa rumakina te paura hydroxyethyl cellulose ki te wai. Mā te whakanui ake i te pH i muri i te rumakina ka āwhina ki te memeha.
5. Kia taea, me tāpiri wawe te aukati harore.
6 Ina whakamahia te peita matotoru teiteiHEC, kaua te kukū o te wai whaea e neke ake i te 2.5-3% (mā te taumaha), ki te kore ka uaua te whakahaere i te wai whaea.
Ngā āhuatanga e pā ana ki te matotoru o te peita rapa
1. Ka nui ake te matotoru o te peita ina nui ake ngā mirumiru hau e toe ana i roto i te peita.
2. He ōrite te nui o te matū whakahohe me te wai i roto i te tauira peita?
3 i roto i te hanganga o te rapa, he nui te ihirangi waikura whakakorikori toenga.
4. Te horopeta o ētahi atu whakamātotoru taiao i roto i te tauira peita me te ōwehenga horopeta ki te karaehe PeitaHEC.)
5. I roto i te tukanga hanga peita, he tika te raupapa o ngā mahi hei tāpiri i te whakamātotoru.
6. Nā te nui rawa o te whakaoho me te nui o te haumākū i te wā e horapa ana.
7. Te horo o te moroiti o te whakamātotoru.
