Ko te Methyl cellulose te whakapotonga o te konutai carboxymethyl cellulose. Ka whakamahia te nuinga ki te kai, ki te hanga, ki te rongoa, ki te karaima, ki te pākahiko, ki te maina, ki te whakakikorua, ki te hanga pepa, ki te horoi, ki te toothpaste matū o ia ra, ki te tuhi pueru me te tae, ki te keri hinu, me etahi atu i roto i te mara. Ko te mahi matua ko te mahi hei kaitao, hei pupuri wai, hei here, hei whakahinuhinu, hei kaiwhakarewa, hei whakaemulsifier, hei kawe hua koiora, papa matrix, me etahi atu. Me pehea te whakarite i te methyl cellulose i te wa e whakamahia ana?
1. Ko te Methylcellulose ano he paura maroke ma, kaore e taea te whakamahi tika i te ahumahi. Me rewa i roto i te wai i te tuatahi kia hanga he kapia puataata i mua i te konatunatua ki te kumete katahi ka whakamahia mo etahi maimoatanga atanga, penei i te whakapiri tira.
2. He aha te ōwehenga o te methyl cellulose? Paura: Me tukatuka te wai i te wa e rite ana ki te tauwehenga o te 1: 150-200, katahi ka whakakorikorihia, me te taapiri i te paura maroke PMC i te wa e whakaoho ana, ka taea te whakamahi i muri i te 1 haora te whakamahi.
3. Mēnā ka whakamahia te methyl cellulose mo te maimoatanga atanga raima, me whai te ōwehenga kāpia → kāpia: ciment = 1:2.
4. Mēnā ka whakamahia te methyl cellulose hei kumete ciment hei ātete ki te pakaru, me whai te ōwehenga kāpia → kāpia: ciment: onepu = 1:3:6.
Me aro tatou ki etahi raruraru ina whakamahi i te methyl cellulose:
1. I mua i te whakamahi okawa i te methyl cellulose, me titiro tuatahi koe ki nga tohu me nga tauira. Ko nga tauira rereke e whakamahi ana i nga tikanga rereke: ina te pH>10 ranei <5, he iti te pokey o te kāpia. Ko te mahinga te tino pumau ina pH=7, a ka tere te piki o te pokey ina kei raro iho te mahana i te 20°C; ka eke te pāmahana ki runga ake i te 80°C, ka denatured te colloid i muri i te whakamahana roa, engari ka tino heke te pokey.
2. Ka taea te whakarite i te methyl cellulose ki te wai matao, ki te wai wera ranei kia rite ki te tauwehenga kua whakaritea. I te wa e whakarite ana, me tapiri he wai i te wa e whakaoho ana. Kia mahara ki te taapiri i te wai katoa me te paura maroke PMC i te wa kotahi. He mea tika kia horoia te paparanga turanga e tika ana kia herea i mua, me etahi o nga paru, nga hinu hinu, me nga papaa wewete me mahi i te waa.
