Koeke peita HEC

Koeke peitaKo te HEC Hydroxyethyl cellulose he momo polymer kore-katote wai-wairewa, he paura ma, he kowhai ranei, he ngawari ki te rere, he hongi me te reka, ka memeha i roto i te wai makariri me te wera, ka piki ake te reiti rewa ki te pāmahana, i te nuinga o te waa kaore e rewa i roto i te nuinga o te waro. whakarewa. He pai te pumau o te PH me te iti o te huringa pokey i te awhe o te ph2-12. He kaha tote tote HEC me te kaha hygroscopic, a he kaha te pupuri wai hydrophilic. Ko tana otinga wai he mahi mata me nga hua pokey teitei he pseudoplasticity teitei. Ka taea te hanga hei kiriata maramara anhydrous me te kaha o te kaha, kaore i te pokea e te hinu, kaore e pa ki te marama, he kiriata wairewa HEC tonu. Whai muri i te maimoatanga o te mata, ka marara a HEC, karekau e whakakotahi ki te wai, engari ka memeha haere. Ka taea te whakatika i te PH ki te 8-10 ka tere te memeha.

Nga taonga matua

Hydroxyethyl cellulose(HEC)ka taea te rewa i roto i te wai matao me te wai wera, karekau he ahuatanga reera. He whānui te momo whakakapinga, te whakarewatanga me te viscosity. He pai te pumau o te waiariki (i raro iho i te 140°C) me te kore e whakaputa i raro i nga tikanga waikawa. rerenga. Ka taea e te otinga hydroxyethyl cellulose(HEC) te hanga i tetahi kiriata maramara, he ahuatanga kore-katote e kore e pahekoheko ki nga katote, he pai hoki te hototahi.

Hei colloid whakamarumaru, ka taea te whakamahi HEC karaehe peita mo te vinyl acetate emulsion polymerization hei whakapai ake i te pumau o te punaha polymerization i roto i te whānuitanga PH. I roto i te hanga o nga hua kua oti ki te hanga i te poaka, te whakakii me etahi atu taapiri kia marara noa, kia pumau me te whakarato i te paanga matotoru. Ka taea hoki te whakamahi mo te styrene, te kiriaku, te kiriaku me etahi atu polymers iri hei dispersants, ka whakamahia i roto i te peita taherapa ka taea te whakapai ake i te matotoru, te whakapai ake i te mahi whakataurite.

Whakatakotoranga Matū

Hua Koeke 

Tikanga tono mo te hydroxyethyl cellulose HEC i roto i te waipeita

1. Tāpiri tika i te wa e huri ana i te poaka: ko tenei tikanga te mea ngawari, he poto te wa e whakamahia ana. Ko nga waahanga taipitopito e whai ake nei:

(1) Tāpirihia he wai parakore tika ki roto i te VAT o te kaitahuri tapahi teitei (ko te tikanga, ko te ethylene glycol, ko te makuku me te kaihanga kiriata ka taapirihia i tenei wa)

(2) Tīmatahia te kōrori i te tere iti ka āta tāpirihia te hydroxyethyl cellulose

(3) Me whakaoho tonu kia ruku nga matūriki katoa

(4) taapirihia te aukati koriri, te kaiwhakahaere PH, etc

(5) Oho kia rewa katoa te hydroxyethyl cellulose (ka tino whakanuia te pokey o te otinga) i mua i te taapiri i etahi atu waahanga ki roto i te tauira, ka huri ki te huri tae noa ki te peita.

2. kua rite rawa ki te wai mama e tatari ana: ko tenei tikanga he mea tuatahi ki te kukū teitei o te wai o te whaea, katahi ka taapirihia te peita taherapa, ko te painga o tenei tikanga he ngawari ake, ka taea te taapiri tika ki te peita i nga hua kua oti, engari me tika te rokiroki. . He rite nga hikoi me nga tikanga ki nga hikoi (1) - (4) i te Tikanga 1, engari kaore e hiahiatia he kaiwhakaoho tapahi teitei, a, ko etahi kaitahuri e tika ana te kaha ki te pupuri i nga muka hydroxyethyl kia marara noa i roto i te otinga. Me whakaoho tonu kia rewa katoa ki te wairewa matotoru. Kia mahara ko te aukati koriri me whakauru wawe ki te waipiro whaea.

3. Paareti rite phenology: I te mea he whakarewa kino nga whakarewa pararopi mo te hydroxyethyl cellulose, ka taea te whakauru i enei whakarewa pararopi ki te pareti. Ko nga whakarewa pararopi e whakamahia nuitia ana penei i te ethylene glycol, propylene glycol, me nga kaihoko hanga kiriata (pēnei i te hexadecanol, diethylene glycol butyl acetate ranei), he waikore te wai tio, no reira ka whakamahia te wai tio ki te wai pararopi i roto i te pāreti. Ko te gruel - penei i te hydroxyethyl cellulose ka taea te taapiri tika ki te peita. Kua kukū te Hydroxyethyl cellulose ki te ahua pāreti. I muri i te taapiri i te waipara, ka memeha tonu ka whai hua te matotoru. Whai muri i te taapiri, me whakaoho tonu kia rewa katoa te hydroxyethyl cellulose me te rite. Ka mahia he paraharaha ma te whakaranu i nga wahanga e ono o te whakarewa pararopi, te wai hukapapa ranei me tetahi waahanga o te hydroxyethyl cellulose. Whai muri i te 5-30 meneti, ko te karaehe peitaHEChydrolyzes ka kitea kake. I te raumati, he nui rawa te makuku o te wai hei whakamahi mo te pareti.

4 .Ko nga mea e tika ana kia aro ki te whakauru i te waipiro mama hydroxyethyl cellulose:

Pwhakatūpato

1 I mua me muri i te taapiri i te karaehe peitaHEC, me whakaoho tonu kia tino marama, kia marama te otinga.

2. Tatarihia te hydroxyethyl cellulose ki roto i te tank ranu. Kaua e whakaurua ki roto i te tank whakaranu i nga rahinga nui, tika ranei ki roto i te karaehe peita nui, porowhita raneiHEC.

3 te pāmahana wai me te uara pH o te wai e kitea ana te hononga ki te whakakorenga o te karaehe peitaHEChydroxyethyl cellulose, na me aro nui ki a ia.

Kaua e tāpirihia he matū taketake ki te ranunga i mua i te kōeke peitaHECKo te paura hydroxyethyl cellulose kua whakamakuku ki te wai. Ko te whakanui ake i te pH i muri i te ruku ka awhina i te memeha.

5 .I te mea ka taea, te taapiri wawe o te aukati koriri.

6 I te wa e whakamahi ana i te taumata peita teiteiHEC, ko te kukū o te waipiro whaea kia kaua e teitei ake i te 2.5-3% (ma te taumaha), mena he uaua te whakahaere i te waipiro whaea.

Nga mea e pa ana ki te pokey o te peita taherapa

1.Ka nui ake nga mirumiru hau i roto i te peita, ka nui ake te pokey.

2. He rite tonu te nui o te kaiwhakaoho me te wai i roto i te tauira peita?

3 i roto i te kōtuitanga o te taherapa, te toenga whakakōkī ihirangi waikura o te nui.

4. Ko te inenga o etahi atu momo whakapouri i roto i te tauira peita me te tauwehenga inenga me te karaehe peitaHEC.)

5.i roto i te mahi peita, e tika ana te raupapa o nga hikoinga ki te taapiri i te whakamatao.

6.Na te nui o te whakaohooho me te makuku nui i te wa e marara ana.

7.Microbial horo o thickener.
