Ka taea e hypromellose te whakakapi i te hydroxyethyl cellulose ki te peita kohatu tuuturu

 

Ko nga hua cellulose ka ahu mai i te miro tuuturu, te penupenu rakau ranei ma te whakaetere.Ko nga momo momo cellulose e whakamahi ana i nga momo etherifying agents.Ko te Hypromellose HPMC e whakamahi ana i etahi atu momo o nga kaihoko whakaetere (chloroform me 1,2-epoxypropane) , i te wa e whakamahia ana e te hydroxyethyl cellulose HEC nga matū whakaetere o Oxirane.Ka taea te whakamahi Hydroxyethyl cellulose hei whakakaha i roto i te peita kohatu tuuturu me te peita latex.Na te nui o te whakahiato, te taumaha motuhake, te ua, me taapiri atu he maatete whakakaha ki te whakanui ake i tona pokey, kia tutuki ai nga hiahia o te rehu rehu hangahanga, me te whakapai ake i te pumau o te rokiroki, me te whakatutuki i tetahi kaha.Ki te whakatutuki i te kaha pai, te pai o te wai me te awangawanga o te rangi, he mea tino nui te kowhiringa o nga rauemi mata me te hoahoa waihanga.https://www.longouchem.com/hpmc/

 

I te nuinga o te waa, ka nui ake te nui o te whakaehunga peita kohatu tuuturu.Hei tauira, kei roto pea i te ton o te peita kohatu tuturu te 300 kg o te whakaehunga kiriaku parakore me te 650 kg o te kirikiri kohatu tae maori.Ina he 50% te kiko totoka o te whakaehunga, ko te rōrahi o te whakaehunga 300 kg i muri i te whakamaroke he 150 rita, ko te 650 Kg o te onepu he 228 rita.Ko te tikanga, i tenei wa ko te PVC (te nui o te poaka) o te peita kohatu tuuturu he 60% , no te mea he nui nga matūriki o te kirikiri tae, he rereke te ahua, i raro i te ahua o te tohatoha rahi o te matūriki, i muri i te whakamaroke. te peita kohatu tūturu pea i roto i te CPVC (te kukū rōrahi pigmenta nui) e pā ana ki.Mo te whakakaha, ki te kowhiria te pokey tika o te cellulose, ka taea te hanga he kiriata ahua oti me te kiko kia tutuki ai nga whakaritenga e toru o te peita kohatu mau.Mena he iti te ihirangi o te whakaehunga, e taunaki ana kia whakamahia he nui ake te pokey o te cellulose hei whakakaha (hei tauira 100,000 viscosity) , ina koa i muri i te pikinga o te utu o te cellulose, ka taea te whakaiti i te nui o te cellulose e whakamahia ana, ka taea hoki te mahi. o te peita kohatu tino pai ake.Ko etahi o nga kaihanga peita kohatu tino utu iti kua whakakapia te hydroxyethyl cellulose ki te hypromellose na te utu me etahi atu whakaaro.Ka whakatauritea ki nga momo cellulose e rua, he pai ake te kaha pupuri wai o te hydroxyethyl cellulose, e kore e ngaro te kaha pupuri wai na te reera i te teitei o te pāmahana, a he parenga ki te koriri.Mo te pai o te mahi, e taunaki ana kia whakamahia te 100,000 viscosity hydroxyethyl cellulose hei whakakaha o te peita kohatu tuuturu.https://www.longouchem.com/modcell-hemc-lh80m-for-wall-putty-product/
