Me pēhea te whakamahi i te hydroxyethyl cellulose i roto i te peita latex
1. Ka whakamahia te Hydroxyethyl cellulose hei hanga porridge: Nā te mea he uaua te rewa o te hydroxyethyl cellulose ki ngā whakarewa waro, ka taea te whakamahi i ētahi whakarewa waro hei whakarite porridge. He ngoikore hoki te wai hukapapa, nō reira ka whakamahia te wai hukapapa me ngā wai waro hei whakarite porridge. Ka taea te tāpiri tika i te hydroxyethyl cellulose rite ki te porridge ki te peita rapa. Kua rumakina katoatia te Hydroxyethyl cellulose ki roto i te porridge. Ina tāpirihia ki te peita, ka tere te rewa, ā, ka mahi hei whakamātotoru. Whai muri i te tāpiri, me whakaoho tonu kia marara katoa te hydroxyethyl cellulose, kia rewa. Ko te tikanga, ka hangaia te porridge 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, ka waikura te hydroxyethyl cellulose, ā, ka pupuhi. (Hei whakamahara he tino tiketike te haumākū o te wai whānui i te raumati, nō reira kaua e whakamahia hei hanga porridge.)
2. Tāpirihia te hydroxyethyl cellulose tika i te wā e huri ana i te tae: He māmā noa iho tēnei tikanga, ā, he poto noa te wā e pau ana. Ko te tikanga taipitopito e whai ake nei:
(1) Tāpirihia te nui e tika ana o te wai parakore ki roto i te peere nui o te mīhini whakaranu kutikuti teitei (ko te tikanga, ka tāpirihia ngā āwhina hanga kiriata me ngā kaihoko whakamakuku i tēnei wā)
(2) Tīmatahia te whakaoho tonu i te tere iti, ā, tāpirihia mārire, ōrite hoki te hydroxyethyl cellulose
(3) Me whakaoho tonu kia marara noa ngā matūriki katoa, kia mākū hoki
(4) Tāpirihia ngā tāpiringa ārai-haruru hei whakatika 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 puta te peita.
3. Whakaritea te hydroxyethyl cellulose me te wai whaea mō te whakamahinga ā muri ake nei: Ko tēnei tikanga he whakarite i te wai whaea me te kukū teitei ake i te tuatahi, kātahi ka tāpirihia ki te peita rapa. Ko te painga o tēnei tikanga he ngāwari ake, ā, ka taea te tāpiri tika ki te peita kua oti, engari me penapena tika. . He rite ngā mahi me te tikanga ki ngā mahi (1)-(4) i te tikanga 2, ko te rerekētanga kāore e hiahiatia he kaiwhakaoho kutikuti teitei, ā, ko ētahi kaiwhakaoho anake he kaha ki te pupuri i te muka hydroxyethyl kia marara ōrite ki roto i te otinga ka taea. Me whakaoho tonu kia memeha katoa ki roto i te otinga matotoru. Me mōhio me tāpiri wawe te kaihoko harore ki te wai whaea peita.
4 Ngā mea hei aro atu i te wā e whakarite ana i te wai whakapūkara hydroxyethyl cellulose
I te mea he paura tukatuka te hydroxyethyl cellulose, he māmā noa iho te whakahaere me te whakarewa ki te wai, mena ka arohia ēnei mea 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 wairewa.
(2) Me āta tātari ki roto i te tāke whakaranu, kaua hoki e tāpiri tika i te nui o te hydroxyethyl cellulose kua hanga hei puranga, hei pōro rānei ki roto i te tāke whakaranu.
(3) He hononga nui tō te pāmahana wai me te uara pH i roto i te wai ki te memeha o te hydroxyethyl cellulose, nō reira me aro nui atu.
(4) Kaua e tāpirihia ētahi matū kawakore ki te ranunga i mua i te whakamakukutanga o te paura hydroxyethyl cellulose ki te wai. Mā te whakanui ake i te pH i muri i te whakamakuku ka āwhina i te whakarewatanga.
(5) Ki te taea, tāpirihia he rongoā ārai harore i te wā e taea ai.
(6) Ina whakamahia te hydroxyethyl cellulose matotoru-teitei, kaua te kukū o te wai matua e neke ake i te 2.5-3% (mā te taumaha), ki te kore ka uaua te whakahaere i te wai matua.
Ngā āhuatanga e pā ana ki te matotoru o te peita rapa:
(1) Nā te nui rawa o te whakaoho, ka wera rawa te haumākū i te wā e horapa ana.
(2) Te nui o ētahi atu matū whakamātotoru taiao i roto i te hanganga peita me te ōwehenga o te nui ki te hydroxyethyl cellulose.
(3) Mēnā he tika te nui o te matū horoi me te nui o te wai i whakamahia i roto i te tauira peita.
(4) I te wā e hanga ana i te rapa, ko te nui o te waikura pērā i te toenga whakakorikori.
(5) Te waikura o te whakamātotoru e ngā moroiti.
(6) I roto i te tukanga hanga peita, mehemea he tika te raupapa taahiraa o te tāpiri i te whakamātotoru.
7 Ka nui ake ngā mirumiru hau e toe ana i roto i te peita, ka nui ake te matotoru
