Te Hydroxyethyl Cellulose i roto i te peita emulsion

Te tikanga whakamahi o te hydroxyethyl cellulose i roto i te peita latex

1. Te pūhui hauwaioraitirime te phenology rite ki te porridge: nā te mea kāore e ngāwari te rewa o te hydroxyethyl cellulose ki roto i ngā whakarewa waro, ka taea te whakamahi i ētahi whakarewa waro hei hanga i te porridge. He wairewa kino hoki te wai hukapapa, nō reira he maha ngā wā ka whakamahia ki roto i te porridge me ngā wai waro. Ka taea te tāpiri tika i te hydroxyethyl cellulose o te āhua congee ki roto i te peita emulsii. Kua whakakīia te Hydroxyethyl cellulose ki roto i te āhua porridge. Ina tāpirihia ki te peita, ka tere te rewa me te matotoru. Me whakaoho tonu kia marara rawa te hydroxyethyl cellulose me te rewa. Ka hangaia he porridge 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. I muri i te 5-30 meneti pea, ka waikura te hydroxyethyl cellulose ka kitea te pikinga. (E kīia ana he tino tiketike te haumākū o te wai i te raumati hei whakamahi mō te porridge.)

2. Tāpirihia te hydroxyethyl cellulose tika ki te tae huri: he māmā noa iho tēnei tikanga, ā, he poto te wā. Ko ngā tikanga taipitopito e whai ake nei:

(1) Tāpirihia te wai parakore e tika ana ki te VAT o te kaiwhakaoho teitei me tapahi (ko te tikanga, ka tāpirihia ngā tāpiringa hanga kiriata me ngā kaihoko whakamakuku i tēnei wā)

(2) Tīmata ki te whakaoho i te tere puhoi, kaua e mutu, ā, tāpirihia mārire te hydroxyethyl cellulose kia ōrite.

(3) Me whakaoho tonu kia marara noa ngā matūriki katoa, kia mākū hoki

(4) Tāpirihia te aukati harore, ka whakatikatika i te uara PH

(5) Whakaohokia kia memeha rawa te hydroxyethyl cellulose (ka tino piki ake te matotoru o te wairewa), kātahi ka tāpirihia ētahi atu wāhanga ki te tauira, ka huri kia huri hei peita.

3. Te tatari mō te wai whaea hydroxyethyl cellulose: ka tāpirihia he wai whaea ki tēnei tikanga, ā, ka tāpirihia he peita rapa, ko te painga o tēnei tikanga he ngāwari ake, ka taea te tāpiri tika i ngā hua peita kua oti, engari kia tika te rokiroki. He rite ngā mahi me ngā tikanga ki ngā mahi (1) – (4) i roto i te Tikanga 2, engari kāore e hiahiatia he whakaoho tapahi teitei, ā, ko ētahi whakaoho anake he nui te kaha hei pupuri i ngā muka hydroxyethyl kia marara noa i roto i te otinga. Me whakaoho tonu kia memeha rawatia hei otinga matotoru. Kia mahara: me tāpiri wawe tonu te kaihoko ārai-haruru ki roto i te wai whaea peita.

4 Ngā mea hei aro atu ina whakauruhia te waikura whaea hydroxyethyl cellulose

I te mea he paura kirikiri te hydroxyethyl cellulose kua rongoatia, he māmā noa iho te whakahaere me te rewa ki te wai mā te whai i ngā whakatūpato e whai ake nei.

(1) I mua atu, ā, i muri i te tāpiri i te hydroxyethyl cellulose, me whakaoho tonu, kia mārama rawa te otinga.

(2) Me ata tātari te hydroxyethyl cellulose ki roto i te tāke whakaoho. Kaua e tāpirihia i roto i te nui, kaua hoki e tāpiri tika ki roto i te tāke whakaoho.

(3) E mārama ana te hononga o te wairewatanga o te hydroxyethyl cellulose ki te pāmahana wai me te uara pH o te wai, nō reira me aro nui ki tēnei.

(4) Kaua e tāpirihia ētahi matū taketake ki te ranunga i mua i te whakamakukuhia o te paura hydroxyethyl cellulose ki te wai. Mā te whakanui ake i te pH i muri i te whakamakuku ka āwhina i te memeha.

(5) Ki te taea, me tāpiri wawe te aukati harore.

(6) Ina whakamahia te hydroxyethyl cellulose matotoru teitei, 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) Nā te nui rawa o te whakaoho me te nui rawa o te haumākū i te wā e marara ana.

(2) te nui o ētahi atu whakamātotoru taiao i roto i te tauira peita me te ōwehenga o te nui kite hauwaitoiretiri pūtau.)

(3) he ōrite te nui o te whakaoho mata me te wai i roto i te tauira peita.

(4 i roto i te hanganga o te rapa, he toenga o te ihirangi waikura whakakorikori o te tau.

Te horomitanga o te whakamātotoru e te moroiti.

6 i roto i te tukanga hanga peita, he tika te raupapa o ngā mahi hei tāpiri i te whakamātotoru.

Ka nui ake ngā mirumiru hau e toe ana i roto i te peita, ka nui ake te matotoru
